FIELD OF THE INVENTION The present invention relates to a novel administration regime useful in the treatment of diseases or conditions where administration of insulin will be of benefit, as well as to kits for use in the same.

BACKGROUND OF THE INVENTION

Diabetes mellitus (DM) is impaired insulin secretion and variable degrees of peripheral insulin resistance leading to hyperglycemia.

Years of poorly controlled hyperglycemia lead to multiple, primarily vascular complications that affect small vessels (microvascular), large vessels (macrovascular), or both. Indeed, diabetes mellitus is one of the major causes of premature morbidity and mortality.

The mechanisms by which vascular disease develops include glycosylation of serum and tissue proteins with formation of advanced glycation end products; superoxide production; activation of protein kinase C, a signalling molecule that increases vascular permeability and causes endothelial dysfunction; accelerated hexosamine biosynthetic and polyol pathways leading to sorbitol accumulation within tissues; hypertension and dyslipidemia that commonly accompany DM; arterial microthromboses; and proinflammatory and prothrombotic effects of hyperglycemia and hyperinsulinemia that impair vascular autoregulation. Immune dysfunction is another major complication and develops from the direct effects of hyperglycemia on cellular immunity. Effective control of blood/plasma glucose can prevent or delay many of these complications but may not reverse them once established. Hence, achieving good glycemic control in efforts to prevent diabetes complications is the primary goal in the treatment of type 1 and type 2 diabetes. Studies also support the role of glycated haemoglobin (HbA _1c ) reduction in decreasing cardiovascular disease risk (Nathan DM, Cleary PA, Backlund JY, et al. Intensive diabetes treatment and cardiovascular disease in patients with type 1 diabetes. N Engl J Med 2005;353:2643-53; Selvin E, Marinopoulos S, Berkenblit G, et al. Meta-analysis: glycosylated hemoglobin and cardiovascular disease in diabetes mellitus. Ann Intern Med 2004;141 :421-31 ). The general goal of an HbA _1c level of below 7% has been recommended by many diabetes organisations (e.g., the American Diabetes Association (ADA)). In the UKPDS, 50% of patients were taking insulin therapy to maintain HbA _1c levels of below 7% within 6 years of the diagnosis of type 2 diabetes.

There are numerous non-insulin treatment options for diabetes, however, as the disease progresses, the most robust response will usually be with insulin. Indeed, since diabetes is associated with progressive β-cell loss, many patients, especially those with long-standing disease, will eventually need to be transitioned to insulin, since the degree of hyperglycemia (e.g., HbA _1c ≥8.5%) makes it unlikely that another drug will be of sufficient benefit.

Most patients express reluctance to beginning injectable therapy, due to discomfort and inconvenience caused by the high demands for blood glucose testing and insulin injection. Traditionally, the use of insulin to improve glycaemic control was provided by medical specialists. With the increasing number of patients under primary care for whom insulin is indicated, prescribing it in the same setting appears much more convenient for the end users. Often however, insulin is not started in time, due to psychological resistance from both doctors and patients.

A consensus statement from the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) was updated in 2012, and emphasised a patient-centred approach and individualised HbA1 c treatment targets for the management of hyperglycaemia in type 2 diabetes (T2DM). It recommended that insulin could be considered as one of the options for dual combination therapy, if an individualised HbA1 c level target was not reached after metformin therapy. This choice could be based on patient and drug characteristics, with an over-riding goal of improving glycaemic control while minimising side-effects. When three-drug combinations are considered, insulin is likely to be more effective than most other agents (e.g., sulfonylurea, thiazolidinedione, dipeptidyl peptidase 4 inhibitor, glucagon-like peptide-1 receptor agonist), especially when the HbA1 c level is very high (≥9.0%) (Inzucchi SE, Bergenstal RM, Buse JB, et al., Management of hyperglycemia in type 2 diabetes: a patient-centered approach: position statement of the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD). Diabetes Care 2012; 35:1364-79).

The ideal insulin regimen aims to mimic the physiological profile of insulin secretion as closely as possible. There are two major components in the insulin profile: a continuous basal secretion and prandial surge after meals. The basal secretion controls overnight and fasting glucose while the prandial surges control postprandial hyperglycaemia. Based on the time of onset and duration of their actions, injectable formulations can be broadly divided into basal (long-acting analogues [e.g., insulin detemir and insulin glargine] and ultra-long-acting analogues [e.g., insulin degludec]) and intermediate- acting insulin [e.g., isophane insulin] and prandial (rapid-acting analogues [e.g., insulin aspart, insulin glulisine and insulin lispro]). Premixed insulin formulations incorporate both basal and prandial insulin components.

There are various recommended insulin regimes, such as (1 ) multiple injection regimen: rapid-acting insulin before meals with long-acting insulin once or twice daily; (2) premixed analogues or human premixed insulin once or twice daily before meals; (3) intermediate- or long-acting insulin once or twice daily. However, where possible, a long-acting insulin regimen alone or in combination with oral antidiabetic drug(s) (OADs) is usually the optimal initial regimen for subjects with T2DM as this reduces the patient burden and discomfort caused by blood glucose measurement and injection of insulin.

Recent data from the United Kingdom Prospective Diabetes Study suggest the importance of stringent glycaemic control (Holman RR, Paul SK, Bethel MA, Matthews DR, Neil HA. 10-year follow-up of intensive glucose control in type 2 diabetes. N Engl J Med 2008; 359: 1577-1589) and current treatment guidelines call for early insulin treatment in type 2 diabetes patients (Nathan DM, Buse JB, Davidson MB et al. Management of hyperglycemia in type 2 diabetes: a consensus algorithm for the initiation and adjustment of therapy: update regarding thiazolidinediones: a consensus statement from the American Diabetes Association and the European Association for the Study of Diabetes. Diabetes Care 2008; 31 : 173-175). However, optimal initiation and titration methods for the long-acting basal insulins are still being determined. Evidence suggests that many patients often do not have insulin doses titrated sufficiently to achieve target levels of glucose control (remaining on suboptimal doses and failing to reach treatment targets) (UK Prospective Diabetes Study (UKPDS) Group).

What has become increasingly clear is that patient empowerment is essential for motivation to reach treatment targets. Self-titration regimens facilitate empowerment of patients, allowing them to become more involved in their treatment, which can result in improved glycaemic control. Until recently, titration of insulin in type 2 diabetes clinical trials was typically left up to the investigator's discretion with a simple statement of the target ranges for glucose. In type 2 diabetes trials the average glycemic control achieved was usually less than desirable. Since then a number of trials have been conducted and reported utilizing various algorithms under various conditions.

During the last decade various insulin titration algorithms have been applied in several trials initiating long or intermediate acting insulin in type 2 diabetes patients often referred to as Treat-to-target. Several of the trials were designed for other primary purposes than algorithm development and have therefore used one specific algorithm. Interpretation of algorithm merit in those cases is somewhat difficult and has to rely on cross trial comparisons. Various factors in addition to the numbers in the algorithm apparently affect the achieved results.

The algorithms for basal insulin titration and their implementation have evolved steadily further away from complete real time health care provider control over every dose decision. The first step was the acceptance of one algorithm for all patients, which at the time was considered radical by most investigators. The second step became acceptance algorithm enforcement.

Controlled clinical trials such as the Diabetes Control and Complications Trial (The effect of intensive treatment of diabetes on the development and progression of long- term complications in insulin-dependent diabetes mellitus. The Diabetes Control and Complications Trial Research Group. N Engl J Med 1993;329:977-86), the UK Prospective Diabetes Study (UKPDS) (Intensive blood-glucose control with sulphonylureas or insulin compared with conventional treatment and risk of complications in patients with type 2 diabetes (UKPDS 33), UK Prospective Diabetes Study (UKPDS) Group. Lancet 1998;352:837-53), the Veterans Affairs Diabetes Trial (Duckworth W, Abraira C, Moritz T, et al. Glucose control and vascular complications in veterans with type 2 diabetes. N Engl J Med 2009;360:129-39), the Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation trial (ADVANCE Collaborative Group, Patel A, MacMahon S, et al. Intensive blood glucose control and vascular outcomes in patients with type 2 diabetes. N Engl J Med 2008;358:2560-72), and a study on Japanese patients (Ohkubo Y, Kishikawa H, Araki E, et al. Intensive insulin therapy prevents the progression of diabetic microvascular complications in Japanese patients with non- insulin- dependent diabetes mellitus: a randomized prospective6-year study. Diabetes Res Clin Pract 1995;28:103-17) demonstrated that intensive glycaemic control could significantly reduce the risk of microvascular complications.

Common to all basal insulin titration algorithms is that dose changes are based on averages of a varying number of days' morning fasting self-monitored blood or plasma glucose. From this general theme there are many variations. The starting dose has been 10 U, 20 U, or based on the morning fasting plasma glucose (FPG) using the formula of Holman and Turner (Holman RR, Turner RC. A practical guide to basal and prandial insulin therapy. Diabet Med. 1985 January;2(1 ):45-53) which is (FPG (mg/dl) - 50)/10, typically yielding just short of 20 U. Within these options there does not appear to be any difference in achieved glycemic control and hypoglycemia rate.

When a clinic has to titrate the insulin dose for the individual patient, there is often a natural limitation on the possible frequency. Consequently, the clinic has to be able to make substantial dose increments at high average glucose so the patient is not left for too long a time in poor glycemic control. However, the patient can easily titrate often, for which there is a long tradition for those with type 1 diabetes. With more frequent titration there may be a reduced need for large dose steps at high glucose levels and the algorithms can be simplified in terms of number of steps. Earlier titration protocols typically titrated an insulin dose based on the average of a week's worth of several fasting blood/plasma measurements. Later trials are based on dose titrations based on average fasting blood/plasma measurements based of 3 measurements per week.. At the extreme is INSIGHT (Gerstein HC, Yale JF, Harris SB, Issa M, Stewart JA, Dempsey E. A randomized trial of adding insulin glargine vs. avoidance of insulin in people with Type 2 diabetes on either no oral glucose-lowering agents or submaximal doses of metformin and/or sulphonylureas. The Canadian INSIGHT (Implementing New Strategies with Insulin Glargine for Hyperglycaemia Treatment) Study. Diabet Med. 2006 July;23(7):736-42), which has only one step of one unit of insulin titrated every morning by the patient.

Clinic contact initially occurred every other week, but after 4 weeks the clinic contact went to every 4 weeks and after 12 weeks to 6-week intervals. Clinic oversight was thus minimally if at all intensified compared to standard clinical practice. Patients were taught to "start with an initial dose of 10 units, and advised to increase this by 1 unit each day until achieving a FPG (FPG) ≤5.5 mmol/liter (99 mg/dl). " The end insulin dose was 38 U and HbA _1c 7.0%. From an effectiveness point of view, this is an "outstanding" result. Hence, there is a trend toward increasingly high frequency of insulin dose titration in order to improve to primary aim of insulin therapy - glycaemic control.

Diabetes care guidelines and product labelling for current basal insulin analogs recommend regular blood glucose self-measurement (American Diabetes Association.

Available at:

Accessed November 13 2012) in order to help people with diabetes maintain appropriate glycemic control and become more actively involved in their healthcare (Benjamin EM. Self-monitoring of blood glucose: the basics. Clin Diabetes. 2002;20(1 ):45-7; Schnell O, Saarlouis HA, Battelino TB, et al. Consensus statement on self-monitoring of blood glucose in diabetes. Diabetes, Stoffwechsel und Herz. 2009;4:285-9; and American Diabetes Association. Insulin administration. Diabetes Care. 2012;35:S1 ). Insulin dose is also typically determined and titrated up or down as needed according to algorithms based on blood glucose results (American Diabetes Association. Standards of Medical Care in Diabetes - 2014. Diabetes Care. 2014;37 SuppI 1 ). Insulin dose determination is individual for each patient. The dose steps (titration model), the glycemic target as well as the absolute insulin dose are determined in an individualised and tailored manner for each individual generally by a healthcare provider (HCP).

Challenges exist that can prevent the achievement of glycemic targets with insulin, including perceptions on the part of patients and HCPs that insulin therapy can be burdensome or too complex to manage (Peyrot M, Barnett AH, Meneghini LF, Schumm-Draeger PM. Factors associated with injection omission/non-adherence in the Global Attitudes of Patients and Physicians in Insulin Therapy Study. Diabetes Obes Metab. 2012; 14:1081 -7; and Peyrot M, Barnett AH, Meneghini LF, Schumm- Draeger PM. Insulin adherence behaviours and barriers in the multinational Global Attitudes of Patients and Physicians in insulin therapy study. Diabet Med. 2012;29:682-90). Patients who take an active role in the management of their diabetes and titration of their insulin may feel more empowered to take charge of their self-care and have a stronger belief that their actions can influence their disease, thus leading to better treatment outcomes (Norris SL, Lau J, Smith SJ, et al. Self-management education for adults with type 2 diabetes: a meta-analysis on the effect of glycemic control. Diabetes Care. 2002;25:1 159-71 ; Kulzer B, Hermanns N, Reinecker H, Haak T. Effects of self-management training in type 2 diabetes: a randomized, prospective trial. Diabet Med. 2007;24:415-23; Anderson RM, Funnell MM, Butler PM, et al. Patient empowerment: results of a randomized controlled trial. Diabetes Care. 1995; 18:943-9). In determining how self-care can best be facilitated for patients with diabetes, the cost and burden of frequent glucose testing must be considered when designing treatment plans, as these can be significant factors when added to the health, quality of life (QoL), and financial toll of poorly controlled diabetes.

Numerous studies investigating the cost of self-measured blood glucose (SMBG) testing have found that it comprises a substantial portion of diabetes-related expenditures (Liebl A, Breitscheidel L, Nicolay C, Happich M. Direct costs and health- related resource utilisation in the 6 months after insulin initiation in German patients with type 2 diabetes mellitus in 2006: INSTIGATE study. Curr Med Res Opin. 2008;24:2349-58; Yeaw J, Christensen TE, Groleau D, Wolden ML, Lee WC. Self- monitoring blood glucose test strip utilization in Canada. Diabetes. 2012;61 (SuppI 1 ):A35; Yeaw J, Lee WC, Wolden ML, Christensen T, Groleau D. Cost of self- monitoring of blood glucose in Canada among patients on an insulin regimen for diabetes. Diabetes Ther. Epub June 27 2012. doi: 10.1007/s13300-012-0007-6; and Yeaw J, Lee WC, Aagren M, Christensen TJ. Cost of self-monitoring of blood glucose in theUnited States among patients on an insulin regimen for diabetes. J Manag Care Pharm. 2012;18:21 -32). In a retrospective database analysis in the US that included more than 45,000 patients, testing accounted for 27% of diabetes care costs: total combined blood glucose testing and insulin-related costs were $2,850 USD/patient/year, with $772 USD/patient/year attributed to blood glucose testing alone (Yeaw J, Lee WC, Aagren M, Christensen TJ. Cost of self-monitoring of blood glucose in the United States among patients on an insulin regimen for diabetes. J Manag Care Pharm. 2012;18:21 -32). In other countries, testing comprises an even higher percentage of diabetes care costs, e.g., 40% in Canada (Yeaw J, Christensen TE, Groleau D, Wolden ML, Lee WC. Self-monitoring blood glucose test strip utilization in Canada. Diabetes. 2012;61 (Suppl 1 ):A35; Yeaw J, Lee WC, Wolden ML, Christensen T, Groleau D. Cost of self-monitoring of blood glucose in Canada among patients on an insulin regimen for diabetes. Diabetes Ther. Epub June 27 2012. doi: 10.1007/s13300-012-0007-6) and 42% in Germany (Liebl A, Breitscheidel L, Nicolay C, Happich M. Direct costs and health-related resource utilisation in the 6 months after insulin initiation in German patients with type 2 diabetes mellitus in 2006: INSTIGATE study. Curr Med Res Opin. 2008;24:2349-58).

Hence, there is pressure to reduce the frequency of blood glucose measurement in order to improve patient quality of life, improve administration regime adherence (leading to improved patient outcomes) and reduce treatment costs. However, there are conflicting pressures to increase the frequency of blood glucose measurement and insulin administration in order to most effectively achieve glycemic control and thereby reduce diabetes-associated complications. Accordingly, there is an ongoing need to provide improved approaches for long- and ultra-long-acting insulin dosing and administration.

DESCRIPTION OF THE INVENTION It is well established that the risk of microvascular and macrovascular complications is related to glycemia, as measured by HbA _1c (glycosylated hemoglobin) - the levels of which reflect the glycemia levels of the subject of the previous 2-3 months. Obtaining target HbA _1c levels remains a major focus of therapy (see, for example, Stratton, et al., 2000.).

The ADA's "Standards of Medical Care in Diabetes" recommends lowering HbA _1c to <7.0% in most patients to reduce the incidence of microvascular disease. This can be achieved with a mean plasma glucose of -8.3-8.9 mmol/L (-150-160 mg/dL); ideally, fasting and pre-meal glucose should be maintained at <7.2mmol/L (<130 mg/dL) and the postprandial glucose at <10 mmol/L (<180 mg/dL). More stringent HbA1 c targets (e.g., 6.0-6.5%) might be considered in selected patients (with short disease duration, long life expectancy, no significant cardiovascular disease) if this can be achieved without significant hypoglycaemia or other adverse effects of treatment. Conversely, less stringent HbA _1c goals, e.g., 7.5-8.0% or even slightly higher are appropriate for patients with a history of severe hypoglycemia, limited life expectancy, advanced complications, extensive comorbid conditions and those in whom the target is difficult to attain despite intensive self-management education, repeated counselling, and effective doses of multiple glucose-lowering agents, including insulin.

The present inventors have surprisingly found that long-acting insulin can be titrated based on a single fasting blood (or plasma) glucose measurement with similar improvements to HbA _1c levels found with traditional titration methods based on three consecutive fasting blood glucose measurements.

This simplified regime allows a patient-focused titration algorithm that would encourage self-titration, enhancing patient empowerment as well as substantially reducing treatment costs by reducing the frequency of blood glucose measurements required for dose adjustments without reducing therapeutic outcomes.

Accordingly, a first aspect of the present invention provides a long-acting insulin for use in treating a disease or condition where administration of insulin will be of benefit, wherein the administration of the long-acting insulin comprises or consists of the following steps:

(a) optionally providing a fasting blood sample to be tested from an individual in need of treatment;

(b) taking a single fasting blood (or plasma) glucose measurement from an individual in need of treatment; (c) using the single fasting blood (or plasma) glucose measurement to determine the long-acting insulin dose to be administered; and

(d) administering the long-acting insulin to the individual at the dose determined in step (c).

Hence, in the present invention, long-acting insulin dosage is not determined or titrated using an average of (and/or selection from) a plurality of blood glucose/plasma measurements. Rather, long-acting insulin dosage is determined or titrated based on a single blood/plasma glucose measurement.

The term "human insulin" as used herein means the human insulin hormone whose structure and properties are well-known. Human insulin has two polypeptide chains, named the A-chain and the B-chain. The A-chain is a 21 amino acid peptide and the B-chain is a 30 amino acid peptide, the two chains being connected by disulphide bridges: a first bridge between the cysteine in position 7 of the A-chain and the cysteine in position 7 of the B-chain, and a second bridge between the cysteine in position 20 of the A-chain and the cysteine in position 19 of the B-chain. A third bridge is present between the cysteines in position 6 and 1 1 of the A-chain. In the human body, the hormone is synthesized as a single-chain precursor proinsulin (preproinsulin) consisting of a prepeptide of 24 amino acids followed by proinsulin containing 86 amino acids in the configuration: prepeptide-B-Arg Arg-C- Lys Arg-A, in which C is a connecting peptide of 31 amino acids. Arg-Arg and Lys- Arg are cleavage sites for cleavage of the connecting peptide from the A and B chains.

An "insulin" or "naturally occurring insulin" according to the invention is herein to be understood as human insulin or an insulin from another species such as porcine or bovine insulin.

The term "insulin peptide" as used herein means a peptide which is either human insulin or an analog or a derivative thereof with insulin activity.

The term "parent insulin" as used herein is intended to mean an insulin before any modifications have been applied thereto. The term "insulin analogue" as used herein means a modified human insulin wherein one or more amino acid residues of the insulin have been substituted by other amino acid residues and/or wherein one or more amino acid residues have been deleted from the insulin and/or wherein one or more amino acid residues have been added and/or inserted to the insulin.

In one embodiment an insulin analogue comprises less than 10 amino acid modifications (substitutions, deletions, additions (including insertions) and any combination thereof) relative to human insulin, alternatively less than 9, 8, 7, 6, 5, 4, 3, 2 or 1 modification relative to human insulin.

Modifications in the insulin molecule are denoted stating the chain (A or B), the position, and the one or three letter code for the amino acid residue substituting the native amino acid residue.

By "desB30" or "B(1 -29)" is meant a natural insulin B chain or an analogue thereof lacking the B30 amino acid and "A(1-21 )" means the natural insulin A chain. Thus, e.g., A21 Gly,B28Asp,desB30 human insulin is an analogue of human insulin where the amino acid in position 21 in the A chain is substituted with glycine, the amino acid in position 28 in the B chain is substituted with aspartic acid, and the amino acid in position 30 in the B chain is deleted.

Herein terms like "A1 ", "A2" and "A3" etc. indicates the amino acid in position 1 , 2 and 3 etc., respectively, in the A chain of insulin (counted from the N-terminal end). Similarly, terms like B1 , B2 and B3 etc. indicates the amino acid in position 1 , 2 and 3 etc., respectively, in the B chain of insulin (counted from the N-terminal end). Using the one letter codes for amino acids, terms like A21A, A21 G and A21 Q designates that the amino acid in the A21 position is A, G and Q, respectively. Using the three letter codes for amino acids, the corresponding expressions are A21Ala, A21 Gly and A21 Gln, respectively.

Herein the terms "A(0)" or "B(0)" indicate the positions of the amino acids N- terminally to A1 or B1 , respectively. The terms A(-1 ) or B(-1 ) indicate the positions of the first amino acids N-terminally to A(0) or B(0), respectively. Thus A(-2) and B(-2) indicate positions of the amino acids N-terminally to A(-1 ) and B(-1 ), respectively, A(- 3) and B(-3) indicate positions of the amino acids N-terminally to A(-2) and B(-2), respectively, and so forth. The terms A22 or B31 indicate the positions of the amino acids C-terminally to A21 or B30, respectively. The terms A23 or B32 indicate the positions of the first amino acids C-terminally to A22 or B31 , respectively. Thus A24 and B33 indicate positions of the amino acids C-terminally to A23 and B32, respectively, and so forth.

Herein, the term "amino acid residue" is an amino acid from which, formally, a hydroxy group has been removed from a carboxy group and/or from which, formally, a hydrogen atom has been removed from an amino group. Examples of insulin analogues are such wherein Pro in position 28 of the B chain is substituted with Asp, Lys, Leu, Val, or Ala and/or Lys at position B29 is substituted with Pro, Glu or Asp. Furthermore, Asn at position B3 may be substituted with Thr, Lys, Gin, Glu or Asp. The amino acid residue in position A21 may be substituted with Gly. Also one or more amino acids may be added to the C-terminal of the A- chaiand/or B-chain such as , e.g., Lys. The amino acid in position B1 may be substituted with Glu. The amino acid in position B16 may be substituted with Glu or His. Further examples of insulin analogues are the deletion analogues, e.g., analogues where the B30 amino acid in human insulin has been deleted (des(B30) human insulin), insulin analogues wherein the B1 amino acid in human insulin has been deleted (des(B1 ) human insulin), des(B28-B30) human insulin and des(B27) human insulin. Insulin analogues wherein the A-chain and/or the B-chain have an N- terminal extension and insulin analogues wherein the A-chain and/or the B-chain have a C-terminal extension such as with two arginine residues added to the C- terminal of the B-chain are also examples of insulin analogues. Further examples are insulin analogues comprising combinations of the mentioned mutations. Insulin analogues wherein the amino acid in position A14 is Asn, Gin, Glu, Arg, Asp, Gly or His, the amino acid in position B25 is His and which optionally further comprises one or more additional mutations are further examples of insulin analogues. Insulin analogues of human insulin wherein the amino acid residue in position A21 is Gly and wherein the insulin analogue is further extended in the C-terminal with two arginine residues are also examples of insulin analogues.

Preferably, the 'ultra-long acting insulin' also: (c) induces in a subject a maximum deviation from mean insulin concentration (AUCF%) over a 24 hour period of < ± 20, for example, < ± 18, < ± 17, < ± 16, < ± 15, < ± 14, < ± 13, < ± 12, < ± 1 1 , < ± 10, < ± 9, < ± 8, < ± 7, < ± 6, < ± 5, < ± 4, < ± 3, < ± 2, < ± 1 , < ± 0.5, < ± 0.1. In principle, the longer the half-life of the insulin, the more stable and evenly distributed the glucose-lowering effect over a dosing interval (i.e. time interval between injections).

In one embodiment, the long-acting insulin or the ultra-long-acting insulin, preferably the ultra-long acting insulin, provides a stable and evenly distributed glucose- lowering effect over a dosing interval. For example, the long acting or ultra-long acting insulin provides a glucose infusion rate (GIR) over a 24-h dosing interval (tau) quantified by estimating the ratio of AUC for sub-areas under the GIR profiles for all four 6-hour measurement intervals (proportion of GIR AUC: AUCGiR,o-6h,ss/AUC _G iR ,ss; AUCGIR,6-12h,Ss/AUCGIR ,SS; AUCGIR,12-18h,Ss AUCGIR, _T ,SS; AUCGIR,18-24h,Ss/AUCGIR ,Ss) Of about 25:25:25:25 % distribution, preferably ± 8%, for example, ± 4%, ± 3%, ± 2%, ± 1 %, ± 0.5% or ± 0.1 %. In one embodiment GIR distribution is evaluated according to the method described in Heise et al., 2012, Diabetes, Obesity and Metabolism, 14(10):944-50. In one embodiment, the ultra-long-acting insulin provides a fluctuation in GIR across a dosing interval of 24 hours, evaluated by AUCF _G IR _,X (the mean fluctuation in GIR profile), of a AUCF _G IR _,t ≤ 0.35 mg/kg/min for an insulin dose of 0.4U/kg, < 0.50 mg/kg/min for an insulin dose of 0.6U/kg and/or < 0.60 or < 0.50 mg/kg/min for an insulin dose of 0.8U/kg, or of a AUCF _G IR _,t ≤ 0.30 mg/kg/min for an insulin dose of 0.4U/kg, < 0.40 mg/kg/min for an insulin dose of 0.6U/kg and/or < 0.45 mg/kg/min for an insulin dose of 0.8U/kg.

In another embodiment, the long-acting insulin provides a fluctuation in GIR across a dosing interval of 24 hours of a AUCF _G IR _,t ≤ 0.40 or < 0.45 mg/kg/min for an insulin dose of 0.4U/kg, < 0.60 mg/kg/min for an insulin dose of 0.6U/kg and/or < 0.80 mg/kg/min for an insulin dose of 0.8U/kg.

AUCF _G | _Rj estimates how much an individual's GIR profile deviates from his/her mean GIR over 24 hours. Fluctuation in GIR (AUCF _G | _Rj ) can be evaluated by any suitable method known in the art. In one embodiment GIR fluctuation (AUCF _G | _R,T ) is evaluated according to the method described in Heise et al., 2012, Diabetes, Obesity and Metabolism, 14(9):859-64. See also for example, Heise et al., Poster EASD 201 1 (Abstract 1046); or Heise et al., Poster ADA 201 1 entitled "Insulin degludec has a two-fold longer half-life and a more consistent pharmacokinetic profile that insulin glargine" (Abstract 37-LB). These references also provide the GIR fluctuation figures for insulin degludec and for insulin glargine, as reported in Table 1 .

Human insulin has three primary amino groups: the N-terminal group of the A-chain and of the B-chain and the ε-amino group of Lys ^B29 . Several insulin derivatives which are substituted in one or more of these groups are known in the prior art. In addition, long acting insulin compositions are known in the art. One main type of long acting insulin compositions comprises injectable aqueous suspensions of insulin crystals or amorphous insulin. In these compositions, the insulin compounds utilized typically are protamine insulin, zinc insulin or protamine zinc insulin. WO 2005/012347 (Novo Nordisk A/S) discloses acylated insulin derivatives comprising additional negatively charge compared to the acylated insulins disclosed in WO 95/07931 . The pharmaceutical formulation of these acylated insulins are given as 2, 3 or 4 zinc atoms per hexamer insulin. WO 2010/049488 discloses an insulin derivative for the treatment of a condition or disease where administration of insulin will be of benefit, comprising administering, to a patient in need thereof, effective dosages of the insulin derivative, wherein said insulin derivative exhibits a prolonged profile of action and wherein said dosages are administered at intervals longer than 24 hours.

According to the present invention, the basal insulin comprises or consists of long-acting insulin and ultra-long acting insulin.

According to the present invention, the basal insulin is administered in an amount to achieve a beneficial glycaemic control in said subject.

According to the present invention, the beneficial glycaemic control in said subject is determined by at least the levels of HbA _1c (glycosylated haemoglobin) in said subject after administration of said basal insulin.

By use of the basal insulin and its administration according to the present invention it is possible to achieve improvements in the proportion of patients in need thereof reaching HbA _1c targets. Fasting blood glucose measurements are typically converted to fasting plasma glucose measurements using standard formulae (typically by multiplying the fasting blood glucose figure obtained by 1 .1 1 ). Fasting blood or plasma glucose measurements may be taken using any suitable method known in the art. However, preferably, fasting blood/plasma glucose samples are assayed using a hexokinase- UV method. More preferably, fasting blood/plasma glucose is performed using a lancet and a glucose monitor for self measurement of blood glucose (SMBG) glucose by the patient. For more information on SMBG see Benjamin, 2002, 'Self-Monitoring of Blood Glucose: The Basics' Clinical Diabetes; 20(1 ):45-47 which is incorporated by reference herein.

Preferably the sample provided is a fasting blood sample (preferably a capillary blood sample) but equally, the fasting blood sample provided may be a plasma sample. When using blood glucose meters the measurement is preferably performed with capillary blood calibrated to plasma equivalent glucose values i.e. the measurement is performed on blood while the value is reported as plasma.

Preferably the fasting blood/plasma glucose measurement is taken at the same time on each day of measurement (or within ± 5 hours of that time, for example, within ± 4.5 hours, within ± 4 hours, within ± 3.5 hours, within ± 3 hours, within ± 2.5 hours, within ± 2 hours, within ± 1 .5 hours, within ± 1 hour, ± 45 min, ± 30 min, ± 15 min, ± 10 min, ± 5 min or ± 1 min if that time). Preferably, the fasting blood/glucose measurement is taken at least 8 hours after eating (most preferably at least 9, 10, 1 1 or 12 hours after eating). Preferably, the fasting blood/glucose measurement is taken before breakfast.

By the term "individual" is meant a human. Preferably, the individual is an adult individual.

(a) (optionally) providing a fasting blood sample to be tested from an individual in need of treatment;

(b) taking a single fasting blood (or plasma) glucose measurement from an individual in need of treatment; (c) using the single fasting blood (or plasma) glucose measurement to determine a long-acting or ultra-long-acting insulin dose to be administered; and

(a) optionally providing a fasting blood sample to be tested from an individual in need of treatment;

(b) taking a single fasting blood or plasma glucose measurement from said individual in need of treatment; and

References herein to step (d) in respect of the third aspect of the invention do not refer to a literal step in the claimed method, but rather, to an administration step performed subsequent to the method of the third aspect, for which the dosage is determined in step (c).

A fourth aspect of the invention provides a kit for use of a long-acting or ultra-long- acting insulin as of first aspect of the invention, a method of treating a disease or condition as of second aspect of the invention or a method of determining an insulin dose as of third aspect of the invention, comprising or consisting of one or more of the following: A) apparatus for providing a blood sample to be tested from an individual in need of treatment;

E) instructions for performing the use of a long-acting insulin as of first aspect of the invention, a method of treating a disease or condition as of second aspect of the invention or a method of determining an insulin dose as of third aspect of the invention.

The long-acting or ultra-long-acting insulin may be administered (or, in respect of aspect three, be for administration) at various frequencies based on a single blood glucose measurement. In one embodiment of the first, second or third aspects of the invention, in step (d), the long-acting insulin is administered (or to be administered) once, or at least once, every 72 hours, for example, the long-acting insulin may be administered once, or at least once, every 64 hours; once, or at least once, every 56 hours; once, or at least once, every 48 hours; once, or at least once, every 42 hours; once, or at least once, every 40 hours; once, or at least once, every 36 hours; once, or at least once, every 32 hours; once, or at least once, every 30 hours; once, or at least once, every 24 hours; once, or at least once, every 18 hours; once, or at least once, every 16 hours; or the long-acting or ultra-long-acting insulin is administered once, or at least once, every 8 hours. In an alternative or additional embodiment of the first, second or third aspects of the invention, in step (d), the long-acting or ultra-long-acting insulin is administered (or to be administered) once, or at least once, every 8 to 72 hours, for example, once, or at least once, every 64 to 8 hours; once, or at least once, every 56 to 8 hours; once, or at least once, every 48 to 8 hours; once, or at least once, every 40 to 8 hours; once, or at least once, every 36 to 8 hours; once, or at least once, every 32 to 16 hours; once, or at least once, every 28 to 20 hours; once, or at least once, every 26 to 22 hours; once, or at least once, every 24 to 8 hours; once, or at least once, every 20 to 8 hours; or said insulin is administered once, or at least once, every 16 to 8 hours. In an alternative or additional embodiment, in step (d), the long-acting or ultra-long- acting insulin is administered (or to be administered) once, or at least once, every 40 to 8 hours (preferably, once every 40 to 8 hours). In an alternative or additional embodiment, the long-acting or ultra-long-acting insulin is insulin degludec and, in step (d), said insulin is administered (or to be administered) once, or at least once, every 40 to 8 hours (preferably, once every 40 to 8 hours). In an alternative or additional embodiment, in step (d), the long-acting or ultra-long- acting insulin is administered (or to be administered) once, or at least once, every 28 to 20 hours (preferably, once every 28 to 20 hours).

In an alternative or additional embodiment, in step (d), the long-acting or ultra-long- acting insulin is administered (or to be administered) once, or at least once, every 24 hours (preferably, once every 24 hours).

As well as being provided at a range of frequencies, the long-acting or ultra-long- acting insulin may be administered for various time periods based upon a dosage determined from a single blood glucose measurement (the administration period).

Hence, in an alternative or additional embodiment of the first, second or third aspects of the invention, step (d) is performed (or is to be performed) for an administration period of, or at least of, 1 day; for example, of, or at least of, 2 days; of, or at least of, 3 days; of, or at least of, 4 days; of, or at least of, 5 days; of, or at least of, 6 days; of, or at least of, 7 days; of, or at least of, 8 days; of, or at least of, 9 days; of, or at least of, 10 days; of, or at least of, 1 1 days; of, or at least of, 12 days; of, or at least of, 13 days; of, or at least of, 14 days or for an administration period of, or at least of, 15 days.

By 'administration period' we mean the period for which the long-acting or ultra-long- acting insulin is administered in a given dose as determined based on the latest single blood glucose measurement. Hence, the long-acting or ultra-long-acting insulin may be administered at a frequency of (for example) once every 24 hours for an administration period of (for example) 7 days. In this event, said insulin would be administered once per day during 7 days at a given dose, after which a further blood glucose measurement would be taken (i.e., step (b)), a further dose to be administered would be determined (i.e., step (c)), and a further dose of said insulin would be administered to the individual for a particular frequency and for a particular administration period (in this example, once per day, for 7 days) (i.e., step (d)) and so on. In this example, the administration period is a period of 7 days between two consecutive titrations. Accordingly, in an alternative or additional embodiment of the first, second or third aspects of the invention, step (d) is performed for an administration period of between 1 and 15 days, for example, between 1 and 13 days; between 2 and 12 days; between 3 and 1 1 days; between 4 and 10 days; between 5 and 9 days; or for an administration period of between 6 and 8 days. Preferably step (d) is performed for an administration period of, or at least of, 7 days. More preferably, step (d) is performed for an administration period of 7 days. More preferably, step (d) is performed for an administration period of 7 days and the insulin is insulin degludec.

Since diseases or conditions where administration of insulin will be of benefit (such as diabetes mellitus) are generally chronic, it is generally necessary to repeat steps (a) to (d) of the first, second or third aspects of the invention. Hence, in an alternative or additional embodiment of the first, second or third aspects the invention comprises or consists of steps (a) to (d) and the following step(s):

(e) repeating steps (a) to (d).

Preferably, step (a) to (d) are repeated for as long as necessary and generally this will be continuous repetition.

Administration periods may be fixed i.e., may be for the same duration for each repetition of steps (a) to (d). However, fasting blood glucose levels may be stable in individuals having stable consumption and activity levels. In such individuals, less frequent adjustment of long-acting insulin dose may be required once a target fasting blood glucose level has been achieved, further reducing the testing burden on the user in terms of discomfort, inconvenience and cost.

Thus, in an alternative or additional embodiment of the first, second or third aspects of the invention, in step (e), steps (a) to (d) are repeated continuously and:

(i) the administration period of each step (d) is of the same duration or same range of duration in each repetition of steps (a) to (d); or

(ii) the administration period of each step (d) is of the same duration or same range of duration in each repetition of steps (a) to (d) until a target fasting blood glucose level is achieved in the individual in need of treatment, after which, the duration or range of duration of the administration period of step (d) in subsequent repetitions of steps (a) to (d) is increased. Although there may be gaps between repetitions of steps (a) to (d) it is preferred that in step (e), steps (a) to (d) are repeated contiguously (i.e., that each administration period directly follows the preceding administration period).

By 'target fasting blood glucose level' we include any target fasting blood glucose level deemed appropriate for a particular patient. Insulin therapies may be highly individual and hence, target fasting blood glucose levels may vary between individuals and between treatment regimes. However, in one alternative or additional embodiment, the target fasting blood or plasma glucose level is 4 to 5 mmol/L (71 to 90 mg/dL).

In an alternative or additional embodiment of the first, second or third aspects of the invention, in step (e)(ii), once the target blood glucose level is achieved in the individual in need of treatment, step (d) is then performed for an administration period of, or at least of, 2 weeks; for example, for an administration period of, or at least of, 3 weeks. Preferably, step (d) is then performed for an administration period of 2 weeks or 3 weeks.

Before increasing the duration of the administration period, it may be preferable to achieve the target fasting blood glucose level for two or more consecutive repetitions of steps (a) to (d) (to ensure that a fasting blood that is sufficiently stable to justify increasing the administration period has been achieved).

Hence, in an alternative or additional embodiment of the first, second or third aspects of the invention, in step (e)(ii) steps (a) to (d) are repeated continuously until the target blood glucose level is achieved in 1 , or at least 1 , step (b), for example, 2, or at least 2, consecutive repetitions of step (b); 3, or at least 3, consecutive repetitions of step (b); 4, or at least 4, consecutive repetitions of step (b); 5, or at least 5, consecutive repetitions of step (b); 6, or at least 6, consecutive repetitions of step (b); 7, or at least 7, consecutive repetitions of step (b); 8, or at least 8, consecutive repetitions of step (b); 9, or at least 9, consecutive repetitions of step (b); 10, or at least 10, consecutive repetitions of step (b). To determine insulin dose in titration step (c), an individual would add or subtract a number of units of insulin based on the blood glucose measurement. This dose adjustment is individual and follows recommendations tailored for each individual generally by a HCP. It also depends on the glycemic target which is also individual and adjusted by a HCP to each individual's need.

Insulin dose may be determined through a variety of methods, for example, may be calculated based on weight (and/or height), fasting blood glucose and gender (thereafter adjusted empirically according to fast blood glucose and/or HbA _1c level outcome). It is increasingly common to use a titration method wherein, after administering an initial dose standard or empirically-determined dose, further doses are adjusted by pre-determined increments (e.g. titration algorithm), as necessary, based on blood glucose/plasma measurements in order to reach and maintain a target blood glucose/plasma and/or HbA _1c level. Such titration models are however always given as guidance only and individual adjustments are applicable on a case by case basis.

Hence, in an alternative or additional embodiment of the first, second or third aspects of the invention in step (c), the long-acting or ultra-long-acting insulin dose to be administered is determined using titration.

In an alternative or additional embodiment of the first, second or third aspects of the invention, in step (b), the single fasting blood (or plasma) glucose measurement is performed using a self-measurement blood glucose (SMBG) test.

In an alternative or additional embodiment of the first, second or third aspects of the invention, prior to step (a) (where present) and step (b), the initial insulin is administered in a first administration period at a predetermined dose (i.e., a dose not based on blood or plasma glucose levels, but rather, based on a preferred starting point for insulin titration).

In an alternative or additional embodiment of the first, second or third aspects of the invention, prior to step (a) (where present) and step (b), the initial insulin is administered in a first administration period at a dose of 10 U.

As used herein the term "U" refers to a unit of insulin (or an analogue or derivative thereof). The designation "U" with a number following indicates the concentration as measured by the number of units per ml of fluid volume (Joslin's Diabetes Deskbook, 2nd edition, Chapter 9 Using insulin to treat diabetes - general principles, page 268). Further information about the meaning of "U" can be found in a document from the EMA (reference EMEA/CHMP/BWP/124446/2005) entitled "Guideline on potency labelling for insulin analogue containing products with particular reference to the use of "International Units" or "Units"" (see http://www.ema.europa.eu/docs/en_GB/docu ment_library/Scientific_guideline/2009/09/WC500003654.pdf). "IU" refers to an international unit of human insulin as defined according to the WHO Expert Committee on Biological Standardization. IU is a standardized parameter. For commercial insulins, the labels indicate the content of 1 U (unit) of the particular insulin analogue.

In an alternative or additional embodiment of the first, second or third aspects of the invention, in step (b), where the single blood or plasma glucose measurement taken from the individual in need of treatment in step (c) is a plasma glucose measurement of:

< 3.9 mmol/L (<70 mg/dL): the dose administered in step (d) is reduced by 4 U compared to the dose previously administered; 4 to 5 mmol/L (71 to 90 mg/dL): the dose administered in step (d) is unaltered compared to the dose previously administered; and

≥5.1 mmol/L (≥91 mg/dL): the dose administered in step (d) is increased by 4 U compared to the dose previously administered.

In an alternative or additional embodiment of the first, second, third or fourth aspects of the invention the long-acting or ultra-long acting insulin, preferably the ultra-long acting insulin, is any one or more of the compounds disclosed in WO 2005/012347, which are incorporated herein by reference.

Typical isotonic agents are sodium chloride, mannitol, dimethyl sulfone and glycerol and typical preservatives are phenol, m-cresol, methyl p-hydroxybenzoate and benzyl alcohol. Examples of suitable buffers are sodium acetate, glycylglycine, HEPES (4-(2- hydroxyethyl)-1 -piperazineethanesulfonic acid), TRIS (2-amino-2-hydroxymethyl-1 ,3- propandiol), and sodium phosphate. Insulin compositions can be used in the treatment of states which are sensitive to insulin. Thus, they can be used in the treatment of type 1 diabetes mellitus, type 2 diabetes mellitus and hyperglycaemia for example as sometimes seen in seriously injured persons and persons who have undergone major surgery. The optimal dose level for any patient will depend on a variety of factors including the efficacy of the specific insulin, analogue or derivative employed, the age, body weight, physical activity, and diet of the patient, on a possible combination with other drugs, and on the severity of the state to be treated. It is recommended that the dosage regimen be determined for each individual patient by those skilled in the art in a similar way as for known insulin compositions, however taking into consideration the present teachings concerning dosage intervals.

Where expedient, the insulin compositions may be used in combination with other types of insulin, e.g. insulin analogues with a more rapid onset of action. Examples of such insulin analogues are described e.g. in the European patent applications having the publication Nos. EP 214826 (Novo Nordisk A/S), EP 375437 (Novo Nordisk A/S) and EP 383472 (Eli Lilly & Co.).

In one embodiment the composition of the invention is as defined in WO 2007/074133 or WO2008/152106.

The long-acting or ultra-long-acting insulin and the one or more additional drug used in the treatment of diabetes may be administered concurrently in the same formulation. In an alternative or additional embodiment of the first, second, third or fourth aspects of the invention, the one or more additional drug used in the treatment of diabetes is, or includes, liraglutide.

In an alternative or additional embodiment of the first, second, third or fourth aspects of the invention, the insulin is LysB29(Ne-hexadecandioyl-v-Glu) des(B30) human insulin (insulin degludec, Tresiba ^® ) and the insulin is administered, concurrently or consecutively, with liraglutide. In an alternative or additional embodiment of the first, second, third or fourth aspects of the invention, the a disease or condition where administration of insulin will be of benefit is selected from the group consisting of diabetes mellitus, such as type 1 diabetes mellitus or type 2 diabetes mellitus, other conditions characterised by hyperglycaemia (such as pre-diabetes, impaired glucose tolerance, metabolic syndrome, obesity, cachexia, in vivo beta-cell loss/death, excessive appetite and inflammation. The term "diabetes" or "diabetes mellitus" includes type 1 diabetes mellitus, type 2 diabetes mellitus, gestational diabetes (during pregnancy) and other states that cause hyperglycemia. The term is used for a metabolic disorder in which the pancreas produces insufficient amounts of insulin, or in which the cells of the body fail to respond appropriately to insulin thus preventing cells from absorbing glucose. As a result, glucose builds up in the blood.

Type 1 diabetes mellitus, also called insulin-dependent diabetes mellitus (IDDM) and juvenile-onset diabetes, is caused by B-cell destruction, usually leading to absolute insulin deficiency.

Type 2 diabetes mellitus, also known as non-insulin-dependent diabetes mellitus (NIDDM) and adult-onset diabetes, is associated with predominant insulin resistance and thus relative insulin deficiency and/or a predominantly insulin secretory defect with insulin resistance.

Hence, in an alternative or additional embodiment of the first, second, third or fourth aspects of the invention, the disease or condition where administration of insulin will be of benefit is diabetes mellitus. The diabetes mellitus may be type 1 diabetes mellitus. The diabetes mellitus may be type 2 diabetes mellitus.

In an alternative or additional embodiment of the first, second, third or fourth aspects of the invention no long-acting insulin, or substantially no long-acting insulin, is administered to the individual in need of treatment other than that administered in step (c).

In an alternative or additional embodiment of the first, second, third or fourth aspects of the invention no insulin, or substantially no, insulin is administered to the individual in need of treatment other than that administered in step (c).

EXAMPLES EXAMPLE 1 - Insulin degludec once-daily in type 2 diabetes: Simple or Stepwise titration (BEGIN™: ONCE SIMPLE USE)

Abstract Introduction: Insulin degludec (IDeg) is a new basal insulin in development with a flat, ultra-long action profile that may permit dosing using a simplified titration algorithm with less frequent self-measured blood glucose (SMBG) measurements and more simplified titration steps than currently available basal insulins.

Methods: This 26-week, multi-center, open-label, randomized, treat-to-target study compared the efficacy and safety of IDeg administered once daily in combination with metformin in insulin-na ^' i ^' ve subjects with type 2 diabetes using two different patient- driven titration algorithms: a "Simple" algorithm (IDeg _S im _P ie), with dose adjustments based on one pre-breakfast SMBG measurement (N=1 1 1 ) versus a "Step-wise" algorithm (IDeg _S t _ep -wise), , with adjustments based on three consecutive pre-breakfast SMBG values (N=1 1 1 ). IDeg was administered using the FlexTouch ^® insulin pen (Novo Nordisk A/S, Bagsvaerd, Denmark), with once-weekly dose titration in both groups. Results: Glycosylated hemoglobin decreased from baseline to Week 26 in both groups (-1.09%, IDegsimpie! -0.93%, IDeg _S te -wise)- IDeg _S im ie was non-inferior to IDegstep-wise in lowering HbA _1c (estimated treatment difference [IDeg _S impie-IDeg _S tep-wise]: -0.16%-points [-0.39; 0.07] _95% ci). Fasting plasma glucose was reduced (-3.27 mmol/L, IDeg _S impie; -2.68 mmol/L, IDeg _S te _P -wise) with no significant difference between groups. Rates of confirmed hypoglycemia (1 .60, IDeg _S impie; 1 -17, IDeg _S te _P -wise events/patient year of exposure [PYE]) and nocturnal confirmed hypoglycemia (0.21 , I Degsimpie; 0.10, I Degstep-wise events/PYE) were low, with no significant differences between groups. Daily insulin dose after 26 weeks was 0.61 U/kg (IDeg _S im _P ie) and 0.50 U/kg (IDegs _te p-wise)- No significant difference in weight change was seen between groups by Week 26 (+1 .6 kg, IDeg _S impie; +1 -1 kg, IDeg _S te _P -wise), and there were no clinically relevant differences in adverse event profiles.

Conclusion: IDeg was effective and well tolerated using either the Simple or Stepwise titration algorithm. While selection of an algorithm must be based on individual patient characteristics and goals, the ability to attain good glycemic control using a simplified titration algorithm may enable patient empowerment through self-titration, improved convenience, and reduced costs.

Introduction Numerous studies investigating the cost of self-measured blood glucose (SMBG) testing have found that it comprises a substantial portion of diabetes-related expenditures [15-18]. In a retrospective database analysis in the US that included more than 45,000 patients, testing accounted for 27% of diabetes care costs: total combined blood glucose testing and insulin-related costs were $2,850 USD/patient/year, with $772 USD/patient/year attributed to blood glucose testing alone [18]. In other countries, testing comprises an even higher percentage of diabetes care costs, (e.g., 40% in Canada [16, 17] and 42% in Germany [15]).

Insulin degludec (IDeg) is a new basal insulin (currently approved in Europe, Japan, Mexico and several other countries) with a flat, ultra-long action profile that may enable subjects to achieve glycosylated hemoglobin (HbA _1c ) levels closer to glycemic target with fewer hypoglycemic episodes [19-21 ]. It was thus hypothesized that IDeg could be titrated once weekly based on a single pre-breakfast SMBG value, offering a simple, patient-focused titration algorithm that would encourage self-titration, enhancing patient empowerment as well as substantially reducing treatment costs by reducing the frequency of blood glucose measurements required for dose adjustments. In this study, after 26 weeks of treatment, we compared the efficacy and safety of two different self-titration algorithms for IDeg administered once daily (OD) plus metformin, in insulin-na ^' i ^' ve subjects with type 2 diabetes: a "Simple" algorithm, in which 4 unit [U] dose adjustments were made based on a single pre- breakfast SMBG measurement was compared with a "Step-wise" algorithm, in which dose adjustments were made in increments of 2 U (Table 2) based on the lowest of three consecutive pre-breakfast SMBG readings. In both groups, IDeg was adjusted once weekly. The objective of this trial was to provide additional guidance on the use of IDeg in clinical practice by investigating whether good glycemic control could be attained with a more simplified titration schedule, involving fewer SMBG tests, than that previously employed during the IDeg Phase 3a development program.

Methods

The study was conducted according to the Declaration of Helsinki (2008) [22] and ICH Good Clinical Practice (1996) guidelines [23], with prior approval by appropriate ethics committees and patient consent obtained in writing prior to the start of any study-related activities. Eligible participants included insulin-na ^' i ^' ve men or women ≥18 years of age, with type 2 diabetes, HbA _1c 7.0-10.0% (inclusive), and body mass index (BMI) <45.0 kg/m ² , who were treated with≥1000 mg/day metformin alone or in combination with one or two other oral antidiabetic medications (OADs) (including a sulfonylurea [SU] or glinide, dipeptidyl peptidase-4 [DPP-4] inhibitors, a-glucosidase inhibitors or thiazolidinediones [TZDs]), with unchanged dosing for≥12 weeks prior to randomization. Participants were ineligible if they had used a glucagon-like-peptide-1 (GLP-1 ) receptor agonist within 12 weeks prior to randomization; had initiated or significantly changed treatment that could interfere with glucose metabolism; had significant disease other than type 2 diabetes; were pregnant or breastfeeding; or had recurrent severe hypoglycemia/hypoglycemia unawareness. Subjects could be withdrawn from the trial due to withdrawal of consent, not fulfilling inclusion/exclusion criteria (randomized in error), non-compliance, or at the discretion of the investigator due to a safety concern. Subjects who were withdrawn after randomization were not to be replaced. This trial is registered at clinicaltrials.gov: NCT01326026.

Study Design and Treatment This was a multinational (conducted in the US, Spain, Finland, and Germany), Phase 3b, multi-center, two-armed, parallel group, open-label, randomized, treat-to-target study that compared the efficacy and safety of IDeg OD [IDeg 100 U/mL, FlexTouch ^® pen, Novo Nordisk A/S, Bagsvaerd, Denmark], adjusted using two different titration algorithms in combination with metformin. The trial consisted of a 26-week period; total study duration was approximately 28 weeks (including 1 week for screening and a 7-day follow-up period). After discontinuing all OADs other than metformin, subjects were randomized 1 :1 by an interactive voice/web response system (IV/WRS) to

B? IDegsimpi _e or IDeg _S t _ep -wise insulin self-titration algorithms, as defined below. Subjects were instructed to self-titrate in accordance with their respective algorithms and continue with their pre-trial metformin dose. At randomization, Week 4 and Week 12, subjects in both treatment arms received diet and exercise counselling by an HCP. The importance of maintaining a healthy diet and exercise plan was reinforced at each visit.

A Novo Nordisk A/S safety committee blinded to treatment performed on-going safety surveillance, but could request unblinding of the data to be performed by an independent ad hoc group, if needed. Blinded insulin titration surveillance was performed by Novo Nordisk A/S.

IDeg was administered OD at a starting dose of 10 U in both groups. Variation of injection time from day to day was permitted, as long as subjects maintained a minimum of 8 and a maximum of 40 hours between injections. Self-adjustment of IDeg dose was to be performed once weekly in both groups according to the algorithms outlined in Table 2. In the IDeg _S im _P ie arm, dose adjustment was based on a single pre-breakfast SMBG measurement. In the IDeg _S te _P -wise arm, dose adjustment was based on the lowest of 3 consecutive days' pre-breakfast SMBG measure.

Efficacy and Safety Assessments

HbA _1c was analyzed using a Bio-Rad high-performance liquid chromatography method at Visits 1 (screening), 2 (randomization), 14 (Week 12) and 28 (Week 26). Fasting plasma glucose (FPG) blood samples were assayed using a hexokinase-UV method at Visits 2, 14 and 28. At the first visit, subjects were provided with a glucose meter for SMBG measurement and instructions for use; blood glucose was measured with test strips calibrated to plasma glucose to obtain PG-equivalent values presented in this report. Subjects performed SMBG measurements before breakfast weekly after randomization and also performed an 8-point SMBG profile prior to Visits 2, 14 and 28.

Adverse events (AEs) and hypoglycemic episodes were documented throughout the study, with confirmed hypoglycemia defined as episodes of severe hypoglycemia (requiring assistance from another person) and episodes with PG value <3.1 mmol/L (56 mg/dL). Nocturnal confirmed hypoglycemic episodes were those occurring between 00:01 h and 05:59 h (inclusive). Laboratory safety variables, insulin dose

3 and body weight were recorded at pre-specified intervals. Two patient- reported outcome (PRO) questionnaires (Device-Specific questionnaires I and II) were self- completed at Visits 14 and 28 to assess subject satisfaction with the FlexTouch ^® pen as an additional trial endpoint. The PRO questionnaire utilized here to assess patient satisfaction with FlexTouch ^® had previously been used in other trials to assess satisfaction with the FlexPen ^® device (Novo Nordisk A/S, Bagsvaerd, Denmark) [24, 25].

Statistical Methods

With 218 subjects, there was 85% power to demonstrate non-inferiority at 0.4% in evaluation of the per-protocol (PP) analysis set (defined as all subjects without major protocol violations who were exposed to treatment for >12 weeks and who had a valid assessment necessary for deriving the primary endpoint), accounting for an anticipated total of 15% that would not be included in the PP analysis set. Sample size was determined using a f-statistic under the assumption of a one-sided test of size 2.5% and a zero mean treatment difference. Data were reported using a 95% confidence interval (CI) and P-values for 1 -sided testing for non-inferiority at alpha=0.025 for the primary analysis, and 2-sided testing with alpha=0.050 for all other analyses. Statistical analyses of all efficacy and patient-reported outcome endpoints were based on the full analysis set (FAS), defined as all randomized subjects, and followed the intention-to-treat (ITT) principle unless otherwise noted. The robustness of the results for change in HbA _1c was explored by an additional analysis of the PP analysis set. Further, robustness was explored by an additional analysis of the set of all subjects who completed the trial and by using a simple model based on the FAS with only treatment and baseline HbA _1c as covariates. Safety endpoints were summarized based on the safety analysis set (SAS), defined as all subjects who received at least one dose of IDeg, and analyzed based on the FAS.

Change from baseline in HbA _1c after 26 weeks was analyzed using an analysis of variance (ANOVA) method with treatment, region, sex and antidiabetic therapy at screening as fixed factors, and age and baseline HbA _1c as covariates. Non-inferiority was considered confirmed if the upper bound of the two-sided 95% CI for the treatment difference (IDeg _S impie-IDeg _S tep-wise) for the mean change in HbA _1c was <0.4%. Change in FPG and change in body weight were analyzed using an ANOVA model similar to that used for the primary analysis, but with the relevant baseline value as covariate for each measure. Responder endpoints (proportion of subjects who achieved target HbA _1c and proportion who achieved target without hypoglycemia) were analyzed using a logistic regression model with the same factors and covariates as those used for the primary analysis. An 8-point SMBG profile included measurements before and 90 minutes after the start of breakfast, lunch and main evening meal, prior to bedtime, and before breakfast the following day. A mixed effect model including treatment, time, interaction between treatment and time, antidiabetic therapy at screening, sex and region as fixed factors, age as covariate and subject as random effect was fitted to the 8-point SMBG profile data. From this model, mean profile by treatment and relevant treatment differences were estimated and explored. Treatment-emergent AEs, hypoglycaemic episodes, laboratory parameters, physical examination, electrocardiogram (ECG), fundoscopy/fundusphotography, vital signs, PRO (Device-Specific questionnaires I and II) and insulin dose were summarized with descriptive statistics. The numbers of treatment-emergent confirmed and nocturnal confirmed hypoglycaemic episodes were analyzed using a negative binomial regression model with a log-link function and the logarithm of the time period for which a hypoglycaemic episode was considered treatment emergent as offset; the model included treatment, sex, region and antidiabetic treatment at screening as fixed factors and age as covariate.

Results

Demographics and Baseline

Participants were allocated 1 :1 to the IDeg _S im _P ie (N=1 1 1 ) and IDeg _S t _ep -wise (N=1 1 1 ) arms (Table 3). Of 222 randomized participants, 221 (99.5%) received trial drug. Treatment arms were well matched at baseline, with the exception of a slightly higher mean body weight and more female subjects in the IDeg _S im _P ie arm. Subjects in the I Degstep-wise arm had a slightly longer mean duration of diabetes. The majority of participants in both groups were taking two OADs at baseline (61/1 1 1 subjects, 55%); -21 % in each group were taking >2 OADs, and -24% in each group were taking 1 OAD. The most common pre-trial OAD other than metformin was a SU. Most (89.2% [99/1 1 1], I Degsimpie! 88.3% [98/1 1 1 ], I Deg _S te -wise) subjects completed the trial. Four I Degsimpie and three I Deg _S t _ep -wise subjects were withdrawn due to AEs; five IDegsimpie and seven IDeg _S t _ep -wise subjects were withdrawn due to meeting withdrawal

5 criteria; and three subjects in each group were withdrawn due to reasons classified as "other" (Fig. 1 ).

HbA _1c decreased from baseline to Week 26 in both groups; -1 .09% with IDeg _S im _P ie, to 7.0%, and -0.93% with I Deg _S t _ep -wise, to 7.2% (Fig. 2a). IDeg _S im _P ie was non-inferior to IDegstep-wise in lowering HbA _1c , as the upper limit of the 95% CI for the estimated treatment difference (ETD) was <0.4%: ETD (I Deg _S impie-IDeg _S tep-wise) -0.16%-points [-0.39; 0.07] ₉₅ %ci. Analyses to measure robustness of results were consistent with FAS results. Significantly more IDeg _Sim pi _e (56.8% [63/1 1 1 ]) than I Deg _S tep-wi _Se (41 .4% [46/1 1 1 ]) subjects achieved HbA _1c <7.0% at end-of-trial; estimated odds ratio (I Degsimpie/I Degstep-wise): 1 -93 [1 .04; 3.55] ₉ 5%ci (P = 0.0356). There was no significant difference in the proportion of patients achieving HbA _1c <7% without confirmed hypoglycemia (40.6% [43/106] I Deg _Si mpie; 34.6% [36/104] IDeg _S te _P -wise); estimated odds ratio (IDeg _S impie/I Deg _S tep-wise): 1 -26 [0.69; 2.29] ₉₅ %ci-

FPG decreased from baseline to Week 26 by 3.27 mmol/L with I Deg _S impie, to 6.1 mmol/L, and by 2.68 mmol/L with I Degstep-wise, to 6.8 mmol/L (Fig. 2b). No significant difference was seen between groups: ETD (I Deg _S impie"I Deg _S tep-wise): -0.57 mmol/l [-1 .30; 0.17] _95%C |. The most pronounced decline in FPG occurred during the first 12 weeks. No difference between groups in 8-point SMBG profiles was seen at any of the eight measured time points at baseline or at end-of-trial (Fig. 2c).

Rates of confirmed hypoglycemia were low, at 1 .60 and 1 .17 events per patient year of exposure (PYE) with I Deg _S impie and I Deg _S te _P -wise, respectively (Fig. 3a), with no significant difference between groups (P = 0.4273). One severe hypoglycemic episode occurred in the I Deg _S impie arm 5 days after the last treatment with IDeg. Observed rates of nocturnal confirmed hypoglycemia were very low at 0.21 (I Degsimpie) and 0.10 (I Deg _S te _P -wise) events per PYE (Fig. 3b), with no significant difference between groups (P = 0.2047).

The observed daily insulin dose after 26 weeks was 62 U (0.61 U/kg) in the I Degsimpie arm and 48 U (0.50 U/kg) in the I Deg _S te _P -wise arm. Up to Week 4, mean doses were similar, after which the mean dose in the Simple arm was higher. The increase in IDeg dose per week began to level off in the I Deg _S te _P -wise arm at Week 14. Although subjects were permitted to adjust their dose by increments larger than 4 U in the I Degstep-wise arm, the mean weekly incremental increase was <3 U.

o Mean baseline body weight was higher in the IDeg _S im _P ie arm (95.7 kg) than in the IDegs _te p-wise arm (91 .3 kg). Modest increases in weight were observed from baseline to Week 26 in both groups: IDeg _S im _P ie: (+1 -6 kg, to mean weight 97.3 kg at Week 26), IDegstep-wise (+1 -1 kg, to mean weight 92.4 kg at Week 26), with no statistically significant difference in weight change: ETD (IDeg _S impie-IDeg _S tep-wise) 0.46 kg [-0.35; 1.26] _95% ci . There were no clinically relevant differences from baseline to end-of-trial or between treatment arms for vital signs, ECG, fundoscopy, physical examination or laboratory parameters (data not shown). No safety concerns were raised during this trial. Please see Table 4 for an overview of the rates of AEs and serious AEs (SAEs) reported. AEs and SAEs were distributed similarly between groups. Most AEs were of mild or moderate severity and the rates of AEs classified as possibly or probably related to trial product by the investigator were low (10.0% [IDeg _S impie]; 7.2% [IDeg _S te _P -wise])- Injection-site reactions (ISRs) were reported by 2.7% (3 subjects with 3 events) of IDeg _S impie and 4.5% (5 subjects with 16 events) of IDeg _S te _P -wise subjects; one subject reported 9 of the 16 total events in the IDegs _te p- _w i _se arm, and reported "pain" as the ninth ISR. No SAEs were reported in≥5% of subjects and none were considered by the investigator to be related to trial product. One death occurred in this study 154 days after starting trial drug in an IDegs _tep -wise-treated participant, due to liver metastasis (the primary cancer was reported as probable small cell lung carcinoma). The event was considered by the investigator to be unlikely related to treatment. One other SAE neoplasm event (astrocytoma [IDeg _S im _P ie]), and three events adjudicated as major adverse cardiovascular events (coronary artery stenosis [IDeg _S im _P ie], acute myocardial infarction [IDeg _S impie] and coronary artery occlusion [IDeg _S te _P -wise]) occurred, all of which were considered by the investigator to be unlikely related to treatment. No IDeg-related medication errors were reported.

In the Device-Specific questionnaires, more than 90% of subjects at Week 12 and Week 26 indicated the highest levels of satisfaction (response category 1 or 2) with the FlexTouch ^® device. At 26 weeks, 98% of subjects reported no problems using FlexTouch ^® and 100% of subjects indicated that they would recommend the pen. Please refer to Table 5 for additional details on the results of the questionnaires (Table 5 contains a subset of the total questions surveyed in this trial).

Discussion Both the Simple and Step-wise titration algorithms were effective, well-tolerated methods of achieving glycemic targets with IDeg, thereby demonstrating that titration based on either a single weekly SMBG measurement with the Simple algorithm, or three measurements with the Step-wise algorithm, provide suitable options for patients with type 2 diabetes. Titration using the Simple algorithm was shown to be non-inferior to titration using the Step-wise algorithm in terms of improving HbA _1c and both methods resulted in a similar FPG reduction. End-of-trial HbA _1c and change from baseline in HbA _1c in both treatment arms were similar to values seen with IDeg in similar previous Phase 3a (BEGIN™) trials in people with type 2 diabetes. These previous trials all demonstrated similar efficacy between IDeg and insulin glargine as demonstrated by non-inferiority in terms of change in HbA _1c , were 26 or 52 weeks in duration, enrolled insulin-na ^' i ^' ve subjects (except for the BEGIN™ Basal-Bolus T2 study in which insulin aspart was dosed with meals [26]) and employed a titration algorithm similar to the Step-wise algorithm, but with weekly titration based on the mean of 3 consecutive days' pre-breakfast SMBG measurements [26-29].

IDeg dose was increased more quickly in the IDeg Simple arm, whereas insulin dose escalation was reduced earlier in the IDeg _S t _ep -wise arm, reflecting a point of differentiation between the algorithms: as pre-breakfast SMBG values approached target, the Step-wise algorithm permitted a smaller dose increase of 2 U versus the recommended 4 U increase in the IDeg _S im _P ie arm. Insulin dose was higher at end-of- trial in the IDeg _S im _P ie arm than in the IDeg _S te _P -wise arm, which may account for the nonsignificant differences seen between groups in FPG and hypoglycemia. FPG values were numerically lower over longer periods of time in the IDeg Simple arm; this may have influenced the observed rates of hypoglycemia, as these rates represented the entire treatment period . The small and non-significant difference in FPG between the IDeg _S im _P ie and IDeg _S t _ep -wise arms likely also contributed to the difference between groups in achieving the HbA _1c target of <7%. It is important to note that there was no significant difference between groups in the achievement of the HbA _1c target without confirmed hypoglycemia.

The Simple algorithm offers an easy and patient-friendly way to titrate IDeg; additionally, the capacity to adjust IDeg doses with a 4 U increase or decrease, based on a single weekly SMBG value, may substantially reduce the financial and time burden and inconvenience of titration measurements. Incidence rates of hypoglycemic episodes were very low, with no significant difference between the Simple and Step-wise arms. As shown in Fig. 3a and Fig. 3b, respectively, end-of- trial confirmed and nocturnal confirmed hypoglycemia rates seen here were comparable to or lower than rates with IDeg administered OD in the BEGIN™ trials in people with type 2 diabetes; rates that, in turn, were lower than or similar to those seen with comparator insulin glargine in other studies of the insulin degludec development program. [26-29]

Subjects in both treatment arms adhered closely to their respective algorithms. The ability and willingness of patients to adhere to a given treatment regimen is an important component in the success of insulin therapy. Surveys of physicians and patients have identified "too busy" and "complicated regimen" as prominent reasons why patients miss or omit insulin injections; 17% of patients report difficulty in adjusting insulin doses, and 60% of patients feel that their insulin regimens can be restrictive [10-1 1 ]. There is evidence to support the premise that if patients are more comfortable with, and accepting of, their dosing regimen, they may be more willing to continue treatment in the long-term [12-14]. Furthermore, patient empowerment may be enhanced by a titration algorithm that facilitates self-adjustment of basal insulin and better adherence to treatment regimens, potentially leading to improved health outcomes. In the Predictable Results and Experience in Diabetes through Intensification and Control to Target: An International Variability Evaluation (PREDICTIVE™) 303 study with insulin detemir, a simplified self-adjusted dosing algorithm in which patients tested SMBG daily and adjusted their dose every 3 days based on the mean of the previous 3 days' values was shown to significantly lower HbA _1c versus standard-of-care, physician-driven adjustments over a period of 6 months [4], thus, providing further evidence that a simple self-titration method can help subjects achieve glycemic targets. Additionally, patient acceptance of the insulin delivery device used to administer doses is a factor that appears to influence adherence and persistence with a given treatment regimen [30-33]. It has been reported that positive perceptions of convenience also play an important role in the persistence of pen use [34]. In this trial, high levels of satisfaction with the FlexTouch ^® insulin pen device were reported in both treatment arms and all subjects indicated that they would recommend the pen to others. This reflects the experiences of patients in other IDeg trials using the same device, in which the majority of patients reported ease in using the pen and a high degree of satisfaction with FlexTouch ^® [35-39].

Conclusion Achieving good glycemic control in patients with type 2 diabetes is an important way to prevent or limit diabetes complications, and control the costs of intensified healthcare utilization stemming from these complications. SMBG is an integral part of effective diabetes management; however, glucose meters, test strips, lancets, and alcohol wipes are consumable items that comprise on-going expenses, with test strips identified as a major driver of these costs [15-18]. New medications and treatment regimens that permit a reduction in the number of SMBG measurements without compromising clinical outcomes would likely benefit all basal insulin-treated patients who may find current algorithms confusing or cumbersome. These patients may be more likely to adhere to a simpler regimen that ultimately results in improved health outcomes and lower healthcare costs. This trial demonstrates that IDeg, titrated using either the Simple or Step-wise algorithm, leads to good glycemic control and is well tolerated, offering individualized titration regimens that best meet patient needs.

EXAMPLE 2 - Assay (I): Insulin receptor binding

The affinity of the insulin-like compounds for use in the present invention for the human insulin receptor was determined by a SPA assay (Scintillation Proximity Assay) microtiterplate antibody capture assay. SPA-PVT antibody-binding beads, anti-mouse reagent (Amersham Biosciences, Cat No. PRNQ0017) were mixed with 25 ml of binding buffer (100 mM HEPES pH 7.8; 100 mM sodium chloride, 10 mM MgS0 ₄ , 0.025% Tween-20). Reagent mix for a single Packard Optiplate (Packard No. 6005190) is composed of 2.4 μΙ of a 1 :5000 diluted purified recombinant human insulin receptor - exon 1 1 , an amount of a stock solution of A14 Tyr[ ¹²⁵ l]-human insulin corresponding to 5000 cpm per 100 μΙ of reagent mix, 12 μΙ of a 1 :1000 dilution of F12 antibody, 3 ml of SPA-beads and binding buffer to a total of 12 ml. A total of 100 μΙ was then added and a dilution series is made from appropriate samples. To the dilution series was then added 100 μΙ of reagent mix and the samples were incubated for 16 hours while gently shaken. The phases were the then separated by centrifugation for 1 min and the plates counted in a Topcounter. The binding data were fitted using the nonlinear regression algorithm in the GraphPad Prism 2.01 (GraphPad Software, San Diego, CA). EXAMPLE 3 - Assay (II): Potency of the insulin derivatives of the invention relative to human insulin Sprague Dawley male rats weighing 238-383 g on the experimental day were used for the clamp experiment. The rats had free access to feed under controlled ambient conditions and were fasted overnight (from 3 pm) prior to the clamp experiment. Experimental Protocol: The rats were acclimatized in the animal facilities for at least

1 week prior to the surgical procedure. Approximately 1 week prior to the clamp experiment Tygon catheters were inserted under halothane anaesthesia into the jugular vein (for infusion) and the carotid artery (for blood sampling) and exteriorised and fixed on the back of the neck. The rats were given Streptocilin vet. (Boehringer Ingelheim; 0.15 ml/rat, i.m.) post-surgically and placed in an animal care unit (25°C) during the recovery period. In order to obtain analgesia, Anorphin (0.06 mg/rat, s.c.) was administered during anaesthesia and Rimadyl (1.5 mg/kg, s.c.) was administered after full recovery from the anaesthesia (2-3 h) and again once daily for

2 days.

The clamp technique employed was adapted from (1 ). At 7 am on the experimental day overnight fasted (from 3 pm the previous day) rats were weighed and connected to the sampling syringes and infusion system (Harvard 22 Basic pumps, Harvard, and Perfectum Hypodermic glass syringe, Aldrich) and then placed into individual clamp cages where they rested for ca. 45 min before start of experiment. The rats were able to move freely on their usual bedding during the entire experiment and had free access to drinking water. After a 30 min basal period during which plasma glucose levels were measured at 10 min intervals, the insulin derivative to be tested and human insulin (one dose level per rat, n = 6-7 per dose level) were infused (i.v.) at a constant rate for 300 min. Plasma glucose levels were measured at 10 min intervals throughout and infusion of 20% aqueous glucose was adjusted accordingly in order to maintain euglyceamia. Samples of re-suspended erythrocytes were pooled from each rat and returned in about ½ ml volumes via the carotid catheter. On each experimental day, samples of the solutions of the individual insulin derivatives to be tested and the human insulin solution were taken before and at the end of the clamp experiments and the concentrations of the peptides were confirmed by HPLC. Plasma concentrations of rat insulin and C-peptide as well as of the insulin derivative to be tested and human insulin were measured at relevant time points before and at the end of the studies. Rats were killed at the end of experiment using a pentobarbital overdose. Test compounds and doses: Insulin-like compounds for use in the present invention to be tested were diluted from a stock solution containing 97 μΜ of the insulin derivative in 5mM phosphate pH 7.7. The final concentration in the solution ready for use was 0.45 μΜ of the insulin derivative, 5 mM of phosphate, 100 mM of sodium chloride, 0.007% of polysorbate 20. The pH was 7.7 and the i.v. infusion rate was 15 and 20 pmol-min ^"1 -kg ^"1 .

A stock solution of human insulin that was used as reference compound was formulated in a similar medium and infused i.v. at 6, 15 or 30 pmol-min ^"1 -kg ^"1 .

Both stock solutions were stored at -20 °C and thawed overnight at 4 °C before use. The solutions were gently turned upside down several times 15 min before they were transferred to the infusion syringes.
