DISEASES

FIELD OF THE INVENTION

[0001] The present invention relates to improved methods for the use of the compound of the invention in the treatment of inflammatory diseases, and/or diseases associated with hypersecretion of IFNa and/or interferons (“interferonopathies”, especially type I interferonopathies), IL- 12 and/or IL-23, by avoiding, contraindicating or discontinuing concomitant use or co-administration of one or more compounds that are cytochrome P450 (CYP) inhibitors and/or P-gp inhibitors, particularly CYP3A4 inhibitors and/or P-gp inhibitors, and more particularly strong CYP3A4 inhibitors and/or strong P-gp inhibitors.

BACKGROUND OF THE INVENTION

[0002] Janus kinases (JAKs) are cytoplasmic tyrosine kinases that transduce cytokine signaling from membrane receptors to STAT transcription factors. Four JAK family members are described, JAK1, JAK2, JAK3 and TYK2. Upon binding of the cytokine to its receptor, JAK family members auto- and/or transphosphorylate each other, followed by phosphorylation of STATs that then migrate to the nucleus to modulate transcription. JAK-STAT intracellular signal transduction serves the interferons, most interleukins, as well as a variety of cytokines and endocrine factors such as EPO, TPO, GH, OSM, LIF, CNTF, GM-CSF and PRL (Vainchenker, Dusa, and Constantine scu 2008).

[0003] The combination of genetic models and small molecule JAK inhibitor research revealed the therapeutic potential of JAK inhibitors (JAKinibs) (Babon et al. 2014). The last decade has seen the development of JAK inhibitors with various degrees of selectivity profdes versus the JAK family members. In particular, whereas targeting multiple JAK may not be detrimental (Brockman, Giovannetti, and Peters 2011), developing selective JAK inhibitors would be very desirable to develop treatment course tailored to the needs of the patient despite the challenge it represents (Fabian et al. 2005). For example, whereas JAK2 inhibition has proven useful in the treatment of polycythemia and myelofibrosis, undesirable effect associated with JAK2 inhibition were observed (O’Shea and Plenge 2012) thus rendering compounds with JAK2 inhibition components unsuitable for the treatment of non-JAK2 mediated diseases.

[0004] Using TYK2 knock out mice, it has been shown that IL-6, IL-10, IL-11, IL-12, IL-13, IL-19, IL- 20, IL-22, IL-23, IL-27, IL-28, IL-29, IL-31, IL-35 and/or type 1 interferons signaling are dependent on TYK2 (Schwartz et al. 2016). However, it has recently been shown that whereas JAK1 is a key driver in IFNa, IL-6, IL- 10 and IL-22 signaling, TYK2 is involved in type I interferons (including IFNa, INF[3), IL- 23 and IL- 12 signaling (Gillooly, Zhang, and Yang 2016). Since the activity of IL- 12 and IL-23 is particularly increased in patients with auto-immune diseases such as psoriasis and/or inflammatory bowel disorders, selective TYK2 inhibition may be particularly advantageous in the treatment of these diseases while avoiding JAK2 dependent erythropoietin (EPO) and thrombopoietin (TPO) signaling (Neubauer et al. 1998). [0005] Furthermore, TYK2 has been reported as a target for multiple autoimmune disorders, providing protection against inflammatory diseases as well as type 2 diabetes with a limited impact on the immune system (Dendrou et al. 2016).

[0006] Compound 1 is a small molecule inhibitor of JAK, a family of tyrosine kinases, more particularly TYK2, and is currently under investigation as a drug for the treatment of inflammatory diseases and/or diseases associated with hypersecretion of IFNa and/or interferons (“interferonopathies”, especially type I interferonopathies), IL- 12 and/or IL-23. The identification and synthesis of Compound 1 have previously been described in WO2019/076716.

[0007] There is an ongoing unmet medical need for the development of new and improved therapies in the treatment of inflammatory diseases and/or diseases associated with hypersecretion of IFNa and/or interferons (“interferonopathies”, especially type I interferonopathies), IL-12 and/or IL-23, in particular diseases such as systemic lupus erythematosus, cutaneous lupus erythematosus, lupus nephritis, dermatomyositis, polymyositis, Sjogren’s syndrome, psoriasis, rheumatoid arthritis, psoriatic arthritis, multiple sclerosis, trisomy 21, ulcerative colitis and/or Crohn’s disease.

[0008] Cytochrome P450 (CYP) enzymes are essential for the metabolism of many medicines and endogenous compounds (Danielson 2002). The cytochrome P450 3 A family is the most abundant subfamily of the CYP isoforms in the liver. There are at least three isoforms: 3A4, 3A5 and 3A7 in adults, of which 3A4 is considered the most important of all CYP enzymes in the liver (Ince et al. 2013).

[0009] CYP enzymes can be inhibited or induced by drugs, which may result in clinically significant drugdrug interactions that may cause unanticipated adverse reactions or therapeutic failures (Lynch and Price 2007). It is therefore crucial to understand which combinations of drugs should be contraindicated or their co-administration avoided.

[0010] Various cytochrome P450 3A4 (CYP3A4) inhibitors are known (https://www.fda.gov/drugs/drug- interactions-labeling/drug-development-and-drug-interactions -table-substrates-inhibitors-and-inducers) and Itraconazole, given its strong CYP3A inhibition, has emerged as probe to evaluate clinical drug-drug interaction (DDI) studies (Liu et al. 2016).

[0011] In a study by (Hu et al. 2020) it has been shown that 64% from the FDA-approved small molecule drugs (2005-2016) is metabolized by CYP3A4, so therefore it is important to mitigate the CYP3 Ad- mediated victim -drug -drug interactions risk, if warranted by the desired clinical profile of the drug.

[0012] Exposure of a drug may be influenced by the co-administration of a CYP3A4 inhibitor (Teo, Ho, and Chan 2015), leading to under or overdosing of said drug; therefore it is essential to ensure stable dose and exposure to avoid undesirable side effects or toxicity.

[0013] P-glycoprotein (P-gp), also referred to as "Multidrug Resistance Protein (MDR1)" and by its gene name "ABCB1", is a member of a class of transport molecules called "ATP Binding Cassette" transporters or "ABC" transporters, which are located in the cell membrane of various tissues of the human body, such as intestines, kidney, liver and at the blood-brain barrier. P-glycoprotein plays an important role transporting drug substances outside the cell (efflux) influencing their elimination from the body. Along with the CYP enzymes, P-glycoprotein is an important mediator of drug -drug interactions. The pharmacokinetics of a drug may be altered when co-administered with compounds which inhibit or induce P-glycoprotein (Konig, Muller, and Fromm 2013). It is therefore crucial to understand which combinations of drugs should be contraindicated or their co-administration avoided.

[0014] The FDA has recognized and listed various drugs as potential P-gp inhibitors (https://www.fda.gov/drugs/drug-interactions-labeling/drug-d evelopment-and-drug-interactions-table- substrates-inhibitors-and-inducers).

[0015] In addition, the co-administration of a substance acting as P-gp inhibitor, which can also act as CYP inhibitor, may result in a reduced therapeutic effect due to a doble effect. On one side, a P-gp inhibition-mediated, enhanced the intracellular accumulation of the parent drug; and on another side, a CYP inhibition-mediated, may cause excessive drug accumulation of the parent drug and increased its toxicity, resulting in the need to reduce the dose of the therapeutic agent. Therefore, it is crucial to understand which combinations of drugs should be contraindicated or their co-administration avoided (Wandel et al. 1999).

[0057] A combined CYP3A4/P-gp inhibitor is a substance that upon administration to a subject decreases CYP3A4 and P-gp mediated activity. In a specific embodiment, the CYP3A4/P-gp inhibitor is Itraconazole. [0058] When ranges are referred to herein, for example but without limitation, Ci-s alkyl, the citation of a range should be considered a representation of each member of said range.

[0059] The present disclosure includes all isotopic forms of the compound of the invention provided herein, whether in a form (i) wherein all atoms of a given atomic number have a mass number (or mixture of mass numbers) which predominates in nature (referred to herein as the “natural isotopic form”) or (ii) wherein one or more atoms are replaced by atoms having the same atomic number, but a mass number different from the mass number of atoms which predominates in nature (referred to herein as an “unnatural variant isotopic form”). It is understood that an atom may naturally exists as a mixture of mass numbers. The term “unnatural variant isotopic form” also includes embodiments in which the proportion of an atom of given atomic number having a mass number found less commonly in nature (referred to herein as an “uncommon isotope”) has been increased relative to that which is naturally occurring e.g. to the level of >20%, >50%, >75%, >90%, >95% or> 99% by number of the atoms of that atomic number (the latter embodiment referred to as an "isotopically enriched variant form"). The term “unnatural variant isotopic form” also includes embodiments in which the proportion of an uncommon isotope has been reduced relative to that which is naturally occurring. Isotopic forms may include radioactive forms (i.e. they incorporate radioisotopes) and non-radioactive forms. Radioactive forms will typically be isotopically enriched variant forms.

[0060] An unnatural variant isotopic form of a compound may thus contain one or more artificial or uncommon isotopes such as deuterium ( ² H or D), carbon-11 ( ⁿ C), carbon-13 ( ¹³ C), carbon-14 ( ¹⁴ C), nitrogen- 13 ( ¹³ N), nitrogen- 15 ( ¹⁵ N), oxygen- 15 ( ¹⁵ O), oxygen- 17 ( ¹⁷ O), oxygen- 18 ( ¹⁸ O), phosphorus-32 ( ³² P), sulphur-35 ( ³⁵ S), chlorine-36 ( ³⁶ C1), chlorine-37 ( ³⁷ C1), fluorine-18 ( ¹⁸ F) iodine-123 ( ¹²³ I), iodine-125 ( ¹²⁵ I) in one or more atoms or may contain an increased proportion of said isotopes as compared with the proportion that predominates in nature in one or more atoms.

[0061] Unnatural variant isotopic forms comprising radioisotopes may, for example, be used for drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e. ³ H, and carbon-14, i.e. ¹⁴ C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Unnatural variant isotopic forms which incorporate deuterium i.e. ² H or D may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Further, unnatural variant isotopic forms may be prepared which incorporate positron emitting isotopes, such as ⁿ C, ¹⁸ F, ¹⁵ 0 and ¹³ N, and would be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy.

[0062] It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed ‘isomers’. Isomers that differ in the arrangement of their atoms in space are termed ‘stereoisomers’.

[0063] ‘ Tautomers’ refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of 7i electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci- and nitro- forms of phenylnitromethane that are likewise formed by treatment with acid or base. Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest.

[0065] The methods for the preparation of Compound 1 have been described in WO2019/076716 (the Compound of the Invention is referred to as “compound 38” in WO2019/076716) and a summary is provided below.

General synthetic methods

[0066] The compounds of the invention can be prepared from readily available starting materials using the following general methods and procedures. It will be appreciated that where typical or preferred process conditions (i.e. reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions can also be used unless otherwise stated. Optimum reaction conditions may vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures.

[0067] Additionally, as will be apparent to those skilled in the art, conventional protecting groups may be necessary to prevent certain functional groups from undergoing undesired reactions. The choice of a suitable protecting group for a particular functional group as well as suitable conditions for protection and deprotection are well known in the art (“Greene’s Protective Groups in Organic Synthesis, 4th Edition | Wiley” 2006)

[0068] The following methods are presented with details as to the preparation of a compound of the invention as defined hereinabove and the comparative examples. A compound of the invention may be prepared from known or commercially available starting materials and reagents by one skilled in the art of organic synthesis. [0069] All reagents were of commercial grade and were used as received without further purification, unless otherwise stated. Commercially available anhydrous solvents were used for reactions conducted under inert atmosphere. Reagent grade solvents were used in all other cases, unless otherwise specified. Column chromatography is performed on silica gel 60 (35-70 pm). Thin layer chromatography is carried out using pre-coated silica gel F-254 plates (thickness 0.25 mm). ^J H NMR spectra were recorded on a Bruker Advance 300 NMR spectrometer (300 MHz). Chemical shifts (5) for ¹ H NMR spectra are reported in parts per million (ppm) relative to tetramethylsilane (5 0.00) or the appropriate residual solvent peak, i.e. CHCI , (5 7.27), as internal reference. Multiplicities are given as singlet (s), doublet (d), triplet (t), quartet (q), quintuplet (quin), multiplet (m) and broad (br). Electrospray MS spectra were obtained on a Waters platform LC/MS spectrometer or with Waters Acquity H-Class UPLC coupled to a Waters Mass detector 3100 spectrometer. Columns used: Waters Acquity UPLC BEH C18 1.7 pm, 2.1 mm ID x 50 mm L, Waters Acquity UPLC BEH C18 1.7 pm, 2.1 mm ID x 30 mm L, or Waters Xterra MS 5 pm C18, 100 x 4.6 mm. The methods are using either MeCN/H2O gradients (H2O contains either 0.1% TFA or 0.1% NH3) or MeOH /H2O gradients (H2O contains 0.05% TFA). Microwave heating is performed with a Biotage Initiator.

PHARMACEUTICAL COMPOSITIONS

[oni] When employed as a pharmaceutical, the compound of the invention is typically administered in the form of a pharmaceutical composition. Such compositions can be prepared in a manner well known in the pharmaceutical art and comprise at least one active compound of the invention according to Formula I. Generally, the compound of the invention is administered in a pharmaceutically effective amount. The amount of compound of the invention actually administered will typically be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound of the invention administered, the age, weight, and response of the individual patient, the severity of the patient’s symptoms, and the like.

[0112] The pharmaceutical compositions of this invention can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intra-articular, intravenous, intramuscular, and intranasal. Depending on the intended route of delivery, the compound of the invention is preferably formulated as either injectable or oral compositions or as salves, as lotions or as patches all for transdermal administration. [0113] The compositions for oral administration can take the form of bulk liquid solutions or suspensions, or bulk powders. More commonly, however, the compositions are presented in unit dosage forms to facilitate accurate dosing. The term ‘unit dosage forms’ refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient, vehicle or carrier. Typical unit dosage forms include prefdled, premeasured ampules or syringes of the liquid compositions or pills, tablets, capsules or the like in the case of solid compositions. In such compositions, the compound of the invention according to Formula I is usually a minor component (from about 0.1 to about 50% by weight or preferably from about 1 to about 40% by weight) with the remainder being various vehicles or carriers and processing aids helpful for forming the desired dosing form.

[0114] Liquid forms suitable for oral administration may include a suitable aqueous or non-aqueous vehicle with buffers, suspending and dispensing agents, colorants, flavors and the like. Solid forms may include, for example, any of the following ingredients, or compound of the inventions of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, citric acid, Primogel, or com starch; a lubricant such as magnesium stearate; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint or orange flavoring.

[0115] Injectable compositions are typically based upon injectable sterile saline or phosphate-buffered saline, or other injectable carriers known in the art. As before, the active compound of the invention according to Formula I in such compositions is typically a minor component, often being from about 0.05 to 10% by weight with the remainder being the injectable carrier and the like.

[0116] Transdermal compositions are typically formulated as a topical ointment or cream containing the active ingredient(s), generally in an amount ranging from about 0.01 to about 20% by weight, preferably from about 0.1 to about 20% by weight, preferably from about 0.1 to about 10% by weight, and more preferably from about 0.5 to about 15% by weight. When formulated as an ointment, the active ingredients will typically be combined with either a paraffinic or a water-miscible ointment base. Alternatively, the active ingredients may be formulated in a cream with, for example an oil-in-water cream base. Such transdermal formulations are well-known in the art and generally include additional ingredients to enhance the dermal penetration of stability of the active ingredients or the formulation. All such known transdermal formulations and ingredients are included within the scope of this invention.

[0117] The compound of the invention can also be administered by a transdermal device. Accordingly, transdermal administration can be accomplished using a patch either of the reservoir or porous membrane type, or of a solid matrix variety.

[0118] The above-described components for orally administrable, injectable or topically administrable compositions are merely representative. Other materials as well as processing techniques and the like are set forth in Part 8 of Remington’s Pharmaceutical Sciences, 17 ^th edition, 1985, Mack Publishing Company, Easton, Pennsylvania, which is incorporated herein by reference.

[0119] The compound of the invention can also be administered in sustained release forms or from sustained release drug delivery systems. A description of representative sustained release materials can be found in Remington’s Pharmaceutical Sciences.

BIOLOGICAL EXAMPLES

Table I. List of abbreviations as used herein above and below:

[0127] The methods for the preparation of the compound of the invention and certain biological examples have been described in WO2019/076716.

[0128] Herewith are provided additional biological examples and data investigating compound 1 as a cytochrome P450 (CYP) and P-gp substrate.

Example 3. In vitro stability study of Compound 1 in human liver microsomes

3.1. Study objective

[0129] The objective of this in vitro study was to determine the stability of Compound 1 in human liver microsomes (HLM) and in human recombinant cytochrome P450 (CYP) enzymes. Following identification of CYP3A4 as the only CYP metabolising enzyme, the kinetic parameters Km (concentration of substrate at which half maximal rate of reaction is reached) and Vmax (maximum rate of reaction) parameters were determined using recombinant enzymes.

3.2. Materials and methods

[0130] Compound 1 was incubated at 3 concentrations (0.1, 0.5 and 1 pM) at 37 °C with HLM (with NADPH) at 0.5 and 2 mg/mL for up to 45 minutes to determine whether sufficient metabolism was observed to warrant further investigation in the presence of specific chemical inhibitors.

[0131] Compoundl (0.1 pM) was also incubated with human recombinant CYP enzymes (1A2, 2B6, 2C8, 2C9, 2C19, 2D6 and 3A4) and NADPH at 37 °C for up to 45 min to identify potential enzymes involved in the metabolism of Compound 1 and to determine conditions for further enzyme kinetics investigations.

[0132] Subsequently, Compound 1 was incubated with human CYP3A4 recombinant enzyme at 11 substrate concentrations (0.08 - 200 pM) in triplicate at 37 °C with NADPH in order to determine the depletion rate constant at each concentration and thus calculate the Km and Vmax values.

[0133] The stability of Compound 1 was assessed by the quantification of the concentration of Compound 1 in the samples using LC-MS/MS analytical method. 5.5. Results of the study

[0134] Compound 1 showed low metabolism in HLM resulting in an intrinsic clearance up to 8.72 pL/min/mg protein.

[0135] No measurable metabolism of Compound 1 was observed following incubation with recombinant CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19 and CYP2D6. Metabolism of Compound 1 was observed following incubation with CYP3A4.

[0136] In the presence of CYP3A4 recombinant enzymes using the substrate depletion approach, the Km for Compound 1 was 4.19±0.414 pM and the calculated Vmax was 1.78 pmol/min/pmol P450 (577 pmol/min/mg microsomal protein).

[0137] In conclusion, Compound 1 is an in vitro substrate of the human CYP3A4 isoform.

Example 4. In vitro stability study of Compound 1 as P-gp substrate

4.1. Study objective

[0138] The objective of these in vitro studies was to inform whether Compound 1 was a potential substrate of the human ABC (efflux) transporter MDR1 (P-gp) and then to determine the kinetic parameters Km and Vmax parameters of Compound 1 with human MDR1 transporter.

4.2. Materials and methods

[0139] Compound 1 was incubated at 3 concentrations (0.625, 2.00 and 6.25 pM; triplicates) in bidirectional permeability assay (monolayer substrate assay) with Madin-Darby canine kidney multidrug resistance 1 (MDCKII-MDR1) transfected cells for 0, 60 and 120 minutes to determine whether there was active transport (direction apical to basolateral [A-B] and basolateral to apical [B-A]). As an active transport was identified, Compound 1 (2 pM; triplicates) was incubated for 120 minutes with MDCKII-MDR1 cells in the presence of a strong MDR1 inhibitor (10 pM valspodar) to confirm the specificity of the MDR1 transporter.

[0140] Subsequently, Compound 1 was incubated with MDCKII-MDR1 cells at 8 concentrations (0.50 - 6.0 pM) in triplicate for 15, 30, 60 and 120 minutes in order to determine the Km and Vmax values to test the unidirectional permeability B-A.

[0141] Bidirectional transport of Compound 1 was determined by quantification of Compound 1 in the samples using a LC-MS/MS analytical method.

4.3. Results of the study

[0142] Compound 1 showed higher permeability in the B-A direction than in the A-B direction, indicating that there was active transport of this compound in the MDCKII-MDR1 cells. Considering the best recovery values (>60%) of Compound 1 at 6.25 pM, the observed net efflux ratio (net ER) was 34.6 after 60 minutes incubation. In the follow-up assay, the net ER decreased from 37.1 to 0.5 in the presence of valspodar, confirming the contribution of MDR1 to the transport of Compound 1 across MDCKII-MDR1 monolayers. [0143] In the unidirectional permeability B-A, the net ER was consistent with the previous results. The kinetic parameters Km was 15.06 pM and Vmax was 8.79 pmol/min.

[0144] In conclusion, Compound 1 is an in vitro substrate of the human MDR1 ABC efflux transporters.

Neutrophil, lymphocyte, and platelet counts must be above the lower limit of normal range. Total bilirubin, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) must be within normal ranges. Other clinical laboratory safety test results must be within the normal ranges or test results that are outside the normal ranges need to be considered not clinically significant in the opinion of the investigator.

• Subject must be able and willing to comply with restrictions on prior medication: all medication (including OTC and/or prescription medication, dietary supplements, nutraceuticals, vitamins and/or herbal supplements [e.g. St John’s wort], oral hormonal contraceptives for WOCBP, and hormonal replacement therapy for postmenopausal subjects) except occasional paracetamol (maximum dose 2 g/day and a maximum of 10 g/2 weeks) should be discontinued at least 2 weeks or 5 half-lives of the drug, whichever is longer, prior to the first dose of Compound 1 administration and throughout the study.

• Negative screen for drugs (amphetamines, barbiturates, benzodiazepines, cannabis, cocaine, opiates, methadone, tricyclic antidepressants) and alcohol.

• Able and willing to comply with the CSP requirements and signing the ICF as approved by the IEC/IRB, prior to any screening evaluations.

• Female subjects should be of non-childbearing potential, defined as permanently surgically sterile (bilateral oophorectomy, i.e. surgical removal of ovaries, bilateral salpingectomy or hysterectomy, i.e. surgical removal of uterus), or with no menses for 12 or more months without an alternative medical cause AND a follicle-stimulating hormone (FSH) level in the postmenopausal range. For surgical sterilization, documented confirmation will be requested.

Female Subjects In line with the HMA’s Clinical Trial Facilitation Group recommendation, female subjects are considered of non-childbearing potential if they meet one of the following criteria: No menses for 12 or more months without an alternative medical cause. A high FSH level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. However in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. Permanently surgically sterile (bilateral oophorectomy, i.e. surgical removal of ovaries, bilateral salpingectomy or hysterectomy, i.e. surgical removal of uterus). All other female subjects are considered to be WOCBP and must use one of the following highly effective methods of birth control prior to the first dose of Compound 1, during the clinical study and for at least 35 days after the last dose of Compound 1:

■ Intrauterine device (non-hormonal).

■ Bilateral tubal occlusion.

■ Sexual abstinence defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the subject. A female subject is not allowed to use any of the following contraception methods in this study:

■ Combined (estrogen and progesterone containing) (oral, intravaginal, transdermal) hormonal contraception associated with inhibition of ovulation.

■ Progesterone-only hormonal (oral, injectable, implantable) contraception associated with inhibition of ovulation.

■ Intrauterine hormone-re leasing system.

■ Periodic abstinence (e.g. calendar, symptothermal, post-ovulation methods), declaration of abstinence for the duration of a clinical study, withdrawal, spermicides only, and lactational amenorrhea method. Hormonal contraceptives are not allowed due to the potential interference with the drug-drug interaction evaluation. In case a WOCBP has a vasectomized partner, provided that partner is the sole sexual partner of the WOCBP clinical study participant and that the vasectomized partner has received medical assessment of the surgical success, then she is not required to use an additional form of contraception. Within these limits, the specific forms of contraception employed are left to the discretion of the subject, the investigator, and/or the subject’s physician. The safety of Compound 1 during breastfeeding is unknown. Nursing women are not allowed to take part in this clinical study. Male Subjects o Non-vasectomized male subjects with female partners of childbearing potential must be willing to use a condom from the time of the first dose of IP, during the clinical study, and until FU, in addition to having their female partner use one of the following forms of contraception:

■ Intrauterine device.

■ Intrauterine hormone-re leasing system.

■ Combined (estrogen and progesterone containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal).

■ Progesterone-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable). o Sexual abstinence defined as refraining from heterosexual intercourse is considered a highly effective contraceptive measure only if it is the preferred and usual lifestyle of the subject. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study. o Periodic abstinence (e.g. calendar, symptothermal, post-ovulation methods), declaration of abstinence for the duration of a clinical study, withdrawal, spermicides only, and lactational amenorrhea method are not acceptable methods of contraception. o In a case where the female partner of a male subject has undergone documented surgical sterilization that was performed more than 1 year before screening, the subject is not required to use an additional form of contraception. o Vasectomized male subjects with female partners of childbearing potential are not required to use an additional form of contraception providing that surgical sterilization has been successful (documented azoospermia by semen analysis). o No sperm donation is allowed from first dose of Compound 1 during the clinical study until FU.
