Description:

COMBINATION THERAPY WITH VILDAGLIPTIN AND METFORMIN

Introduction

The invention relates to a DPP-IV inhibitor (preferably vildagliptin or a pharmaceutically acceptable salt thereof), and metformin or a pharmaceutically acceptable salt thereof, for use in treating type 2 diabetes. The invention also relates to the use of a DPP-IV inhibitor (preferably vildagliptin or a pharmaceutically acceptable salt thereof), and metformin or a pharmaceutically acceptable salt thereof, in the manufacture of a medicament for treating type 2 diabetes. The invention also relates to a method of treating type 2 diabetes using a DPP-IV inhibitor (preferably vildagliptin or a pharmaceutically acceptable salt thereof), and metformin or a pharmaceutically acceptable salt thereof.

Background

Diabetes mellitus is a chronic metabolic disorder characterized by the presence of hyperglycaemia (raised blood glucose concentrations). It may be divided into four general subclasses, including i) type 1 or insulin-dependent diabetes mellitus (IDDM) (caused by b- cell destruction and characterized by absolute insulin deficiency), ii) type 2 or non-insulin- dependent diabetes mellitus (NIDDM) (characterized by impaired insulin action and impaired insulin secretion), iii) other specific types of diabetes (associated with various identifiable clinical conditions or syndromes such as genetic defects of beta-cell function e.g. maturity- onset diabetes of the young types 1 - 3 and point mutations in mitochondrial DNA), and iv) gestational diabetes mellitus.

The prevalence of type 2 diabetes is high and is growing at an alarming rate. The global burden of diabetes mellitus is expected to reach 300 million by the year 2025, with more than 90% of these individuals having type 2 diabetes.

The predominant pathophysiological defects leading to hyperglycaemia in type 2 diabetes are impaired insulin action (insulin resistance) and impaired insulin secretion (beta-cell dysfunction). Treating hyperglycaemia is therapeutically important in diabetes mellitus in order to prevent symptoms caused by the raised blood glucose concentrations, such as polyuria (excessive urination) and polydipsia (excessive thirst), and to reduce the risk of diabetic complications. The chronic hyperglycaemia of diabetes mellitus is associated with significant, often devastating long-term complications in the eyes, kidneys, nerves and blood vessels. In a large study of pharmacotherapy in type 2 diabetes, “The United Kingdom Prospective Diabetes Study” (UKPDS), demonstrated that lowering blood glucose concentrations with pharmacotherapy in type 2 diabetes reduces the risk of complications [Lancet 352:837-853, 1998]. The study showed that there was no lower threshold for the benefits of glucose lowering and that any additional glucose lowering would further reduce the risk of development of diabetic complications. The UKPDS also demonstrated that an inexorable decline in beta-cell function occurs with time in type 2 diabetes [Diabetes 44:1249-1258,

1995]. This leads, in the majority of patients, to worsening of glycaemic control with time, requiring addition of more and more therapies as the disease progresses.

Guidelines for the management of hyperglycaemia in type 2 diabetes recommend metformin as first-line pharmacological therapy with sequential intensification and second-line therapy only when glycaemic control (glycated haemoglobin A1c [HbA _1c] £ 53 mmol/mol or £ 7.0%) is not achieved. One such second-line therapy involves administering a combination of metformin and the DPP-IV inhibitor vildagliptin. However, with clinical inertia, treatment intensification is often delayed, resulting in loss of glycaemic control and exposure to avoidable hyperglycaemia. The UKPDS established that early treatment to lower glycaemia using metformin monotherapy was associated with reduction in myocardial infarction, diabetes-related deaths, and all-cause mortality, and a legacy of continued benefit after 10 years. Achieving early glycaemic control within the first 12 months of diagnosis is desirable, as this improves long-term glycaemic durability and reduces the risk of associated complications.

There is a desire in the art for new therapies which are able to treat type 2 diabetes. In particular, there is a desire to provide new therapies which are able to provide greater and more durable long-term benefits compared with the current standard-of-care initial metformin monotherapy for patients with newly diagnosed type 2 diabetes.

Summary of the Invention

The present invention arose as a result of a 5-year efficacy and safety study which compared an early combination therapy of metformin and vildagliptin, with the current standard-of-care (which initially administers metformin monotherapy, with the combination of metformin and vildagliptin being introduced only when the metformin monotherapy fails). The inventors have demonstrated for the first time that early intervention with a combination therapy of metformin and vildagliptin provides greater and more durable long-term benefits compared with the current standard-of-care in patients with type 2 diabetes. The invention provides long-term clinical benefits more frequently and without tolerability issues. In addition, the inventors found that the early intervention with the combination therapy was unexpectedly associated with a reduced risk of cardiovascular events.

Definitions

As used herein, the term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge, et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference.

As used herein, the term “glycaemic control” refers to a state in patients with type 2 diabetes mellitus where the patient’s HbA _1c level is below a certain threshold, which is typically 53 mmol/mol (7%). If a patient’s HbA _1c level is at or above the threshold for a certain amount of time, for example if two measurements taken 13 weeks apart both show an HbA _1c level at or above the threshold, the glycaemic control has been lost.

As used herein, the term “monotherapy” is a therapy which uses a single drug to treat a disease or condition. A type 2 diabetes mellitus patient who is treated with a monotherapy will receive only a single antidiabetic drug. The term “metformin monotherapy” refers to a monotherapy which comprises the administration of metformin or a pharmaceutically acceptable salt thereof, to the patient as a sole antidiabetic drug. Typically, the metformin is administered as metformin hydrochloride in metformin monotherapy. As used herein, the term “subsequent” in the context of “metformin monotherapy followed by subsequent co-administration of a DPP-IV inhibitor (preferably vildagliptin or a pharmaceutically acceptable salt thereof) and metformin or a pharmaceutically acceptable salt thereof” is differentiated from the initial administration of a combination of DPP-IV inhibitor (preferably vildagliptin or a pharmaceutically acceptable salt thereof) and metformin or a pharmaceutically acceptable salt thereof according to the invention. In particular, “subsequent” in this context means that metformin monotherapy has already been administered for a relatively long period of time, e.g. several days, months or years, prior to commencement of the second-line therapy, but has been discontinued prior to commencement of the second-line therapy due, for example, to loss of glycaemic control.

As used herein, the term “patient” includes, but is not limited to mammals. Preferably, the patient is a human patient.

As used herein, the term “treating” and its variants (e.g. “treat”, “treatment” etc.) is understood as the management and care of a patient for the purpose of combatting the disease, condition or disorder.

As used herein, the term “prevent” and its variants (e.g. “preventing”) refers to the ability of a drug, or a combination of drugs, to stave off the occurrence of a clinically undesirable disease, disorder, symptom, or condition for a clinically significant period of time. For example, the combination of drugs herein may prevent loss of glycaemic control by staving off the loss of glycaemic control for a period of 5 years or more.

As used herein, “HbA _1c” refers to glycated haemoglobin, i.e. to haemoglobin which is covalently linked to a sugar (e.g. glucose) molecule. Elevated levels of HbA _1cin the bloodstream are indicative of diabetes mellitus. Methods of detecting and measuring levels of HbA _1c are known to the skilled person. Typically, these methods involve taking a blood sample from a patient and determining the HbA _1c level in the sample. This may be done using, for example the Quo-Test® HbA _1c Analyzer (available from EKF Diagnostics), the Quo-Lab® HbA _1c Analyzer (also available from EKF Diagnostics), or the Afinion™ HbA _1c (available from Abbott). As used herein, the term “adverse event” refers to any unfavourable and unintended sign, symptom, or disease associated with the use of the medicinal product, whether or not considered related to the medicinal product.

As used herein, the term “cardiovascular event” is an event which may cause damage to the heart and/or circulatory system. The term “cardiovascular event” encompasses, but is not limited to a “macrovascular event”. Macrovascular events include, but are not limited to, cardiovascular death, non-fatal myocardial infarction or stroke, and hospital admission for heart failure.

As used herein, “hypoglycaemia” is when blood glucose levels fall below the normal range. For example, a patient having hypoglycaemia may have a blood glucose level of less than 4 mmol/L (72 mg/dL).

As used herein, the term “dose” refers to the amount of a drug substance which is administered to a patient. A dose may be given to the patient in a single administration, or a dose may be given in multiple separate administrations.

As used herein, the term “co-administration” and its variants (e.g. “co-administer”, “co administered” etc.) is a reference to the administration of more than one drug to treat a disease or condition in a patient. The term “co-administration” includes, but is not limited to, administration of two or more drugs simultaneously in a single dosage form (e.g. a fixed-dose combination tablet), administration of two or more drugs simultaneously in separate dosage forms, and administration of two or more drugs sequentially in separate dosage forms. When two or more drugs are co-administered sequentially, they are administered separately with a time interval between each administration. This time interval is less than one day, for example less than 12 hours, less than one hour or typically less than several minutes (in particular less than one minute).

The invention will now be described with reference to the following example. For the avoidance of doubt, this example does not limit the scope of the invention, which is defined in the appended claims. Example 1 - the VERIFY studv protocol and results

“Vildagliptin Efficacy in combination with metfoRmln For earlY treatment of type 2 diabetes” (VERIFY) was a randomised, double-blind, parallel-group study of newly diagnosed patients with type 2 diabetes conducted in 254 centres across 34 countries. The study consisted of a 2-week screening visit, a 3-week metformin-alone run-in period, and a 5-year treatment period, which was further split into study periods 1 , 2, and 3. During the 5-year treatment period, treatment was initially intensified when loss of glycaemia occurred and thereafter when clinically indicated, at the discretion of study investigators (see Fig. 1).

In the trials, metformin was administered as metformin hydrochloride and vildagliptin was administered as vildagliptin free-base.

The study is registered with clinicaltrials.gov, NCT01528254.

Key Inclusion and Exclusion Criteria

The trial enrolled individuals aged 18-70 years with type 2 diabetes, diagnosed within 2 years as per local diagnostic criteria, with centrally confirmed HbA _1cof 48 - 58 mmol/mol (6.5 - 7.5 %) and body-mass index (BMI) of 22 - 40 kg/m ². Only patients who received appropriate lifestyle modification advice before enrolment, including diet counselling and exercise training were included in the study. Individuals were excluded if they were receiving glucose-lowering treatment (except metformin £ 2000 mg daily within 1 month prior to first screening visit) within 3 months prior to screening, or for more than 3 consecutive months or a combined total of more than 3 months in the past 2 years. Individuals were also excluded if they were using any weight-loss medications within 3 months prior to screening, had chronic liver disease or ongoing congestive heart failure (New York Heart Association Functional Classification 111— IV), or were pregnant or nursing.

Randomisation and Masking

Patients were randomly assigned in a 1 :1 ratio either to the early combination treatment group or to the initial metformin monotherapy group, with the help of an interactive response technology system (Cenduit Interactive Response Technology, version 1 .48.1 ; Nottingham, UK) and simple randomisation without stratification. Patients, investigators, clinical staff performing the assessments, and data analysts were masked to treatment allocation. For the study period 1 , patients in the monotherapy group received a placebo in addition to the existing stable dose of metformin. Patients in study periods 2 and 3 were masked for the use of combination therapy. The use of insulin in study period 3 was open label (Fig. 1).

Procedures

After the 2-week screening visit, all eligible participants entered a run-in period of metformin up-titration (targeting 1500 mg per day or maximum tolerated dose). At the end of the run-in period, participants who were able to tolerate at least 1000 mg per day of metformin entered study period 1 and were randomly assigned to receive either the early combination treatment with metformin (stable daily dose of 1000 mg, 1500 mg, or 2000 mg) and vildagliptin 50 mg twice daily, or standard-of-care initial metformin monotherapy (stable daily dose of 1000 mg, 1500 mg, or 2000 mg) and placebo twice daily (Fig. 1) All doses of metformin (500 mg tablet form) and vildagliptin (50 mg tablet form) were administered orally twice daily, as single tablets. Dose adjustment of metformin in both treatment groups was permitted during the first 4 weeks in the trial, to allow adjustment to a dose of 2000 mg per day or the maximum tolerable dose of at least 1000 mg per day post-randomisation. No adjustment was allowed afterwards. HbA _1c was measured every 3 months. If the initial treatment did not maintain HbA _1c below 53 mmol/mol (7.0%) confirmed at two consecutive scheduled visits which were 13 weeks apart, patients in the metformin monotherapy group received vildagliptin 50 mg twice daily in place of the placebo and entered study period 2, during which all patients received the combination therapy. Patients in both groups received vildagliptin in a medication pack designed differently from the vildagliptin or placebo packs used in period 1 . At study period 3, rescue therapy with insulin was added to the metformin and vildagliptin combination therapy, to maintain glycaemic control in patients as per local diabetes treatment guidelines and as per investigator discretion. Patients discontinued study treatment if an alternative glucose-lowering medication was considered by the treating physician. Study procedures were completed every 13 weeks when participants visited the study site. Safety assessments were completed at every study visit and included collection of all adverse events and serious adverse events. Outcomes

The primary efficacy endpoint was the time from randomisation to initial treatment failure, defined as HbA _1c measurement of at least 53 mmol/mol (7.0%) at two consecutive scheduled visits, 13 weeks apart from randomisation through period 1 (the earliest possible failure time is 6 months). The secondary endpoints can be summarised as: progression of HbA _1c after the start of period 2 to the end of period 2 assessed by rate of loss in glycaemic control over time, both by threshold (second treatment failure) and slope of glycaemia; progression of fasting plasma glucose over time assessed by estimated annualised slope; change in HbA _1c based on baseline characteristics; and safety and tolerability. The specific secondary endpoints were rate of loss of glycaemic control during period 1 ; rate of loss of HbA _1c over time during period 2; rate of loss in glycaemic control in fasting plasma glucose (FPG) during period 1 ; rate of loss in glycaemic control in FPG during period 2; rate of loss of beta cell function from baseline to end of study; rate of change of insulin sensitivity from baseline to end of study; adverse events, serious adverse events and death. Exploratory endpoints included analysis of cardiovascular outcomes as assessed by time to first adjudicated macrovascular event, including cardiovascular death, non-fatal myocardial infarction or stroke, or hospital admission for heart failure.

Statistical Analysis

The statistical analysis plan with one primary efficacy endpoint was finalised prior to unlocking treatment codes for analysis. A specific order of analysis was redefined for the analysis approach in the updated statistical analysis plan in order to avoid methodological duplication and potential dilution of alpha spending. The planned sample size of 1000 patients per treatment approach was expected to provide an approximate 75% power to detect a risk reduction of 25% in time to initial treatment failure with the combination treatment approach, compared with monotherapy. The full analysis set included patients who received at least one randomised study medication and had at least one post-randomisation efficacy parameter assessed. The safety analysis set included all patients who received at least one dose of randomised study medication. Comparability of the two treatment approaches was assessed by demographic and baseline characteristics. The primary efficacy endpoint of time to initial treatment failure was measured in the full analysis set with a Cox proportional hazards regression model that included treatment approach and geographical region as factors and baseline HbA _1c as a covariate. The time to second treatment failure during period 2 was measured in the full analysis set using the same Cox regression model. Kaplan-Meier estimates for cumulative probability of initial and second treatment failure over time were assessed. In simple terms, in each treatment strategy arm, the first treatment failure is defined as two consecutive values of HbA _1c of at least 53 mmol/mol (7.0%) and the second treatment failure as two further consecutive values of HbA _1c of at least 53 mmol/mol (7.0%). All patients contributed to the Kaplan-Meier comparator in each group. The monotherapy comparator group comprised patients with one treatment failure (in period 1) who were receiving the vildagliptin combination in period 2, as well as those on metformin monotherapy without treatment failure in period 1. Subgroup analyses for time to initial treatment failure were done using similar Cox regression analyses and treatment-by-subgroup interaction was assessed. Mean HbA _1c values and change from baseline by treatment approach and visit were evaluated. The proportion of patients with HbA _1c below 53 mmol/mol (7.0%), 48 mmol/mol (6.5%), and 42 mmol/mol (6.0%) were assessed over time during the study. Loss of glycaemic control, assessed by the annualised slope of HbA _1c over time from week 26 to the end of period 1 , was measured with a linear mixed effect model that included treatment approach and region as factors, baseline HbA _1c and time of HbA _1c measurement (in years) as covariates, and interaction of treatment approach by time. An unstructured covariance method was used. Cls and p values for secondary endpoints and subgroup effects have not been adjusted for multiplicity. Briefly, for the primary efficacy variable, patients who prematurely discontinued during period 1 were included as no event at the time of discontinuation (i.e., censored for time values at the time of discontinuation). Equally, patients remaining under glycaemic threshold or with no confirmed value above it at the next scheduled visit, were included as no event and only censored for time during the last study visit. When assessing the primary endpoint, available HbA _1c values were used without imputation for missing values. For the analysis of second treatment failure, patients remaining in period 1 contributed to the percentage of patients without treatment failure, and for those with treatment failure in period 1 but not in period 2, time from randomisation to the end of period 2 was calculated as no event (censored for time). Significance in the analyses was established on the basis of a two-sided 0.05 significance level (equivalent to a one-sided 0.025 significance level). Adverse events were summarised as number and percentage of patients having any adverse event by treatment group and in each primary system organ class. Hypoglycaemic events, microvascular and macrovascular complications were assessed separately. Time to first adjudicated macrovascular events were assessed using the Cox regression model and all suspected macrovascular events were subject to adjudication. The incidence of neoplasms were compared using the X ² test. The statistics program used for analyses was SAS (version 9.4; Cary, NC, USA).

Results

Of the 4524 participants screened, 2001 eligible participants were randomly assigned to either the early combination treatment group (n=998) or the initial metformin monotherapy group (n=1003; Fig. 2). Of the 2001 eligible patients, 1710 were aged between 18 and 64, and 291 patients were aged 65 and over. The most common reasons for study exclusion were HbA _1c outside the protocol-defined range and metformin intolerance prior to up-titration. A total of 1598 (79.9%) patients completed the 5-year study; 811 (81 .3%) in the early combination therapy group and 787 (78.5%) in the monotherapy group (Fig. 2). The median follow-up time was 59.8 months (IQR 59.4 - 60.0) for patients in the early combination treatment group and 59.8 months (IQR 59 3-60 0) for patients in the monotherapy group. 17 patients in the combination treatment group and 24 in the monotherapy groups were lost to follow-up. This is summarised in Table 1 below:

Table 1 - Participant Flow Table. Overall study

Baseline demographic and clinical characteristics were similar between treatment groups. Mean age of the patients at randomisation was 54.1 (SD 9.5) years in the combination treatment group and 54.6 (9.2) years in the monotherapy group, and mean BMI was 31.2 (SD 4.8) kg/m ² in the combination treatment group and 31 .0 (4.7) kg/m ² in the monotherapy group. Mean HbA _1c at randomisation was 50.0 (SD 4.4) mmol/mol in the combination treatment group and 50.0 (5.5) mmol/mol in the monotherapy group (table 1). 937 (93.9%) of 998 patients in the combination treatment group and 937 (93.4%) of 1003 patients in the monotherapy group had concomitant medications equally administered during the study for management of prevalent concomitant conditions. A similar proportion of patients in both treatment groups (405 [40.6%] in the combination treatment group and 412 [41 .1%] in the monotherapy group) received metformin less than 4 weeks prior to study entry. A few female patients (one in the combination treatment group and three in the monotherapy group) received short-term insulin because of gestational diabetes prior to having been diagnosed with type 2 diabetes. This is summarised in Table 2 below.

The incidence of initial treatment failure during period 1 was 429 (43.6%) patients in the combination treatment group and 614 (62.1%) patients in the monotherapy group. The median observed time to treatment failure in the monotherapy group was 36.1 (IQR 15.3 - not reached [NR]) months, while the median time to treatment failure time for those receiving early combination therapy could only be estimated to be beyond the study duration at 61 .9 (29.9 - NR) months. A significant reduction in the relative risk (RR) for time to initial treatment failure was observed in the early combination treatment group compared with the monotherapy group over the 5-year study duration (hazard ratio [HR] 0.51 [95% Cl 0.45 - 0.58]; p<0.0001 ; Fig. 3 (top)). The RR for time to second treatment failure during period 2 was also significantly reduced in the combination treatment group compared with monotherapy group (HR [95% Cl]: 0.74 [0.63, 0.86], p<0.0001 ) (Fig. 3 (bottom)). There was also a consistently lower HbA _1c observed over time with the combination treatment group compared with the monotherapy throughout the study duration, with a greater proportion of patients in the early combination treatment group with HbA _1c below 53 mmol/mol (7.0%), 48 mmol/mol (6.5%), and 42 mmol/mol (6.0%). Subgroup analyses for time to initial treatment failure revealed a consistently significant benefit of early combination treatment over monotherapy for the primary outcome (Fig. 4). This benefit was shown for predefined subgroups of HbA _1c, BMI, age, gender, smoking status, race, geographical regions, and estimated glomerular filtration rate (eGFR) categories, with no evidence of heterogeneity. Results and statistical analysis associated with the primary efficacy endpoint (time to initial treatment failure) are given below in Tables 3 and 4.

Glycaemic control also deteriorated more rapidly in the monotherapy group than in the early combination treatment group. The difference in adjusted mean rate of change in HbA _1c per year (coefficient of failure) was -0.02 (SD 0.01; 95% Cl -0.05 to 0.00; two-sided p=0.085) at the end of period 1. Over the 5-year study, mild reduction in body weight from baseline was reported in patients treated with early combination therapy as well as metformin monotherapy.

During the trial, all potential cardiovascular events were subject to adjudication. Over the 5- year study duration, a numerical reduction in the risk of time to first adjudicated macrovascular event was seen with the early combination treatment approach compared with initial monotherapy (HR 0.71 [95% Cl 0.42-1.19]; two-sided p=0.19). Adjudicated first macrovascular events occurred in 24 (2.4%) of patients in the combination treatment group and in 33 (3.3%) of patients in the monotherapy group. The absolute cumulative number of recurrent events by treatment approach was low (30 in the combination treatment group vs 44 in the monotherapy group). The overall safety and tolerability profile was similar between treatment approaches, with no unexpected safety findings reported. The incidence of adverse events and serious adverse events, excluding the cardiovascular events described above but including those considered to be related to the study drug, were similar between the treatment groups (833 (83.5%) had adverse events and 166 (16.6%) had serious adverse events in the combination treatment group, 833 (83.2%) had adverse events and 183 (18.3%) had serious adverse events in the monotherapy group. The incidence of hypoglycaemic events was low, all of them were grade 1 and similar between groups (13 [1 .3%] in the combination treatment group, 9 [0.9%] in the monotherapy group). The incidence of events related to pancreatitis (4 [0.4%] in the combination treatment group, 3 [0.3%] in the monotherapy group) and pancreatic carcinoma (3 [0.3%] in the combination treatment group, 2 [0.2%] in the monotherapy group) was also low in both groups. The incidence of neoplasms was low and not significantly different between treatment groups (62 [6.2%] in the combination treatment group vs 54 [5.4%] in the monotherapy group; p=0.43). No bullous pemphigoids were reported. Elevated liver function tests were also rare and balanced between groups. Overall, the 4% annualised rate of discontinuation was low compared with the anticipated rate of 11%, and similar between the groups (4.1% in the combination treatment group, 5.3% in the monotherapy group). 22 deaths were reported during this study (13 in the combination treatment group, 9 in the monotherapy group), none of which were considered related to the study drugs (Fig. 2). The safety results of the VERIFY trial are given in the following tables.

Discussion

The VERIFY study has shown that early combination treatment with metformin and vildagliptin improves glycaemic durability in patients with type 2 diabetes compared with standard-of-care initial metformin monotherapy followed by sequential combination with vildagliptin. Early combination treatment significantly reduced the probability of initial treatment failure, the time to second treatment failure, and the time to treatment failure compared with monotherapy throughout the 5-year study duration. Secondary glycaemic parameters (loss of glycaemic control) support the durability of the combination approach. The longer time to second treatment failure in the combination treatment group showed that the observations were not simply the result of comparing a therapy of two drugs with a therapy of one, since all patients entering period 2 received the combination therapy. Finally, the early combination treatment was safe and well tolerated.

VERIFY is the first study to examine long-term clinical benefits of an early combination treatment strategy and provides a step forward with respect to previous approaches. What was considered as intensive therapy in UKPDS is the comparator treatment strategy in VERIFY, reflecting enhanced understanding of the pathophysiological mechanisms underlying the progressive nature of type 2 diabetes and the expanded therapeutic armamentarium.

The early combination treatment was well tolerated, with no signal for adverse events of special interest, in line with previous evidence from vildagliptin studies. As part of safety surveillance, cardiovascular events were monitored and adjudicated. Surprisingly, an imbalance favouring the early combination treatment was observed. Such an observation, obtained in a low-risk population, is unexpected because it is at odds with the neutral cardiovascular effect reported in cardiovascular outcomes trials of patients with long-standing type 2 diabetes and much greater cardiovascular risk. It is noteworthy that no other anti diabetic medication has demonstrated any benefit in preventing primary cardiovascular events to date.

In conclusion, the strategy of an early combination treatment approach with vildagliptin plus metformin in patients with newly diagnosed type 2 diabetes significantly and consistently improves long-term glycaemic durability compared with metformin monotherapy. The results indicate that long-term clinical benefits can be achieved more frequently and without tolerability issues with early combination treatment compared with standard-of-care metformin monotherapy.
