Description

[0001] SUBSTITUTED PYRAZINE-2-CARBOX AMIDES AS HPK1 INHIBITORS FOR THE TREATMENT OF CANCER

[0002] TECHNICAL FIELD

[0003] The technical field relates to certain substituted pyrazine 2-carboxamides of Formula (I), and pharmaceutically acceptable salts thereof, together with compositions containing them and their use in therapy. The compounds of Formula (I) are inhibitors of hematopoietic progenitor kinase 1 (HPK1) and are thereby particularly useful in the treatment or amelioration of abnormal cell proliferative disorders such as cancer.

[0004] BACKGROUND

[0005] In recent years, discovery of immunological check points and their inhibition has unveiled a new avenue for targeting cancer by harnessing the body’s own immune system to fight tumours. While check point therapy has shown great promise in several tumour types, only a fraction of cancer patients respond, novel therapies are needed to reach a broader range of patients.

[0006] T cells are critical in the cancer immunity cycle (Nature, 541 (2017), 321-330; Nature Reviews Immunology, 20, (2020), 651-668); they are the effector cells which recognize and kill tumour cells. In cancer patients, T cells are driven to exhaustion in the tumour microenvironment by chronic exposure to antigen and become non -functional. Additionally, suppressive signals in the tumour such as PGE2, TGFβ, adenosine, etc. hamper the function of these cells. Therapies that enhance T cell function and rescue the function of exhausted T cells therefore result in improved tumour control.

[0007] HPKl (hematopoietic progenitor kinase 1), also known as mitogen activated protein kinase 1 MAP4K1, a Ste20-related serine / threonine kinase that is expressed only in hematopoietic cells acts as a negative regulator of T cell signalling and tumouricidal cytokine production. Following TCR ligation, HPKl phosphorylates its target SLP76 at Ser376 causing SLP76 to associate with 14-3-3 which results in disassociation of the LAT signalosome (J. Cell Biol., 195 (2011), 839-853; Nat. Immunol., 8 (2007), 84-91) and thus restricts T cell activation (J. Exp. Med., 204 (2007), 681-91). Loss of HPKl or inactive kinase (kinase dead) causes enhanced activation of T cells resulting in increased cytokine secretion and proliferation (Nat Immunol., 8. (2007), 84-91; Cell Reports, 25 (2018), 80-94). HPKl can also inhibit T cell signalling in response to immunosuppressive prostaglandin E2 (PGE2) through protein kinase A (PKA) (Blood, 101 (2003), 3687-89; J. Biol. Chem., 282 (2007), 34693-99; Cancer Immunol. Immunother., 59 (2010), 419-29). Recent literature has described the essential function of the kinase domain of HPK1 in driving tumour surveillance, inactivation of the kinase domain of HPK1 prevents tumour progression in murine tumour models. Importantly, studies comparing wildtype and kinase dead mice show that loss of kinase function of HPK1 can rescue T cells from exhaustion in chronic viral infection and PGE2 high tumour models (Nat Immunol., 8. (2007), 84-91; Cell Reports, 25 (2018), 80-94). Apart from its function in T cells, HPK1 is also reported to act as a negative regulator in other immune cells such as B cells, dendritic cells and NK cells which would also contribute to tumour immunity (Elife, 2020, 9). The kinase activity of HPK1 has been implicated as essential for the regulation of T cell function (Cell Reports, 25 (2018), 80-94), supporting the development of small molecule inhibitors of HPK1 for use in cancer immunotherapy to boost T cell function as well as other immune cell types. HPK1 protein contains an N-terminal kinase domain, which is the regulatory domain containing the ATP binding site amino acids 23-46 (EMBO J., 15, 1996, 7013-25). The intermediate domain has proline-rich motifs with binding sites for SH3- containing proteins such as Crkl, Grb2 and HIP-55 which suggests a scaffolding function. The Citron homology domain is at the C-terminal which may act as a regulatory domain in molecular interactions including T cell adhesion. LCK and ZAP70 induce HPK1 Tyr-379 phosphorylation and kinase activation (Oncogene, 20 (2001), 1703-14; Immunity, 12 (2000), 399-408; J. Biol. Chem., 276 (2001), 45207-16. Essential adapters for T cell (SLP76) and B cell (BLNK) signalling have been reported to bind to activated HPK1 aiding in blockade of downstream signalling in both T and B cells (J. Biol. Chem., 276 (2001), 18908-14). Collectively there is strong rationale for targeting HPK1 with small molecule kinase inhibitors for cancer immunotherapy.

[0008] An HPK1 inhibitor can be used alone or in combination with other therapeutic agents for the treatment of cancer. An HPK1 inhibitor could be used in combination with check point blockade PD-(L)1 axis or with CTLA4 in efforts to expand response rates to check point blockade. Primary or secondary resistance to check point blockade may be potential indications for an HPK1 inhibitor. Additional combinations may include radiation, chemotherapy, surgery, tumour targeted agents or other immune targeted agents.

[0009] An HPK1 inhibitor could be used as a therapeutic in multiple cancer indications. A number of small molecule inhibitors of HPK1 have been disclosed in patent applications, for example as summarized in Expert Opinion on Therapeutic Patents, DOI: 10.1080 / 13543776.2021.1924671.

[0570] It shall be noted that any one of these specific compounds may be disclaimed from any of the herein mentioned embodiments.

[0571] In one embodiment there is provided a process for the preparation of compounds of Formula (I) or pharmaceutically acceptable salts of compounds of Formula (I), and the intermediates used in the preparation thereof.

[0572] Another embodiment is a product obtainable by any of the processes or examples disclosed herein.

[0573] MEDICAL AND PHARMACEUTICAL USE

[0574] The compounds of Formula (I) and their pharmaceutically acceptable salts are useful because they possess pharmacological activity as inhibitors of hematopoietic progenitor kinase 1 (HPK1) and are thereby particularly useful in the treatment or amelioration of abnormal cell proliferative disorders such as cancer. The compounds of Formula (I) are inhibitors of HPK1. Thus, the compounds of Formula (I) can be used as a medicament, in particular for disorders, disease or conditions responsive to inhibition of HPK1, and more specifically cancer.

[0575] In a further embodiment there is provided a pharmaceutical formulation comprising a compound of Formula (I), or a pharmaceutically acceptable salt of a compound of Formula (I), for use in the treatment of a condition where inhibition of HPK1 would be beneficial.

[0576] In a further embodiment there is provided a compound of Formula (I), or a pharmaceutically acceptable salt of a compound of Formula (I), for use in therapy, especially in the prevention or treatment of cancer in a mammal, particularly a human.

[0577] In a further embodiment there is provided the use of a compound of Formula (I), or a pharmaceutically acceptable salt of a compound of Formula (I), for the manufacture of a medicament for the treatment of cancer.

[0578] In still a further embodiment, administration of a compound of Formula (I), or a pharmaceutically acceptable salt of a compound of Formula (I) results in a reduction in levels of activity of HPK1 in a mammal, particularly a human.

[0579] For the above-mentioned therapeutic indications, the dosage administered will, of course, vary with the compound employed, the mode of administration and the treatment desired. However, in general, satisfactory results are obtained when the compounds are administered at a dosage of the solid form of between 1 mg and 2000 mg per day.

[0580] The compounds of Formula (I), and pharmaceutically acceptable derivatives thereof, may be used on their own, or in the form of appropriate pharmaceutical compositions in which the compound or derivative is in admixture with a pharmaceutically acceptable adjuvant, diluent or carrier. Thus, another aspect concerns a pharmaceutical composition comprising a novel compound of Formula (I), or a pharmaceutically acceptable salt thereof, in admixture with a pharmaceutically acceptable adjuvant, diluent or carrier. Administration may be by, but is not limited to, enteral (including oral, sublingual or rectal), intranasal, inhalation, intravenous, topical or other parenteral routes. Conventional procedures for the selection and preparation of suitable pharmaceutical formulations are described in, for example, Pharmaceuticals - The Science of Dosage Form Designs , M. E. Aulton, Churchill

[0581] Livingstone, 2nd Ed. 2002. The pharmaceutical composition preferably comprises less than 80% and more preferably less than 50% of a compound of Formula (I), or a pharmaceutically acceptable salt thereof. PHARMACOLOGICAL PROPERTIES

[0582] The compounds of Formula (I) or pharmaceutically acceptable salts thereof are believed to be useful in the prevention or treatment of disorders, disease or conditions responsive to inhibition of HPK1, and more specifically cancer.

[0583] For the avoidance of doubt, as used herein, the term “treatment” includes therapeutic and / or prophylactic treatment.

[0584] When a compound or salt described herein is administered as therapy for treating a disorder, a “therapeutically effective amount” is an amount sufficient to reduce or completely alleviate symptoms or other detrimental effects of the disorder, cure the disorder, reverse, completely stop, or slow the progress of the disorder or reduce the risk of the disorder getting worse.

[0585] The compounds described herein are thus indicated both in the therapeutic and / or prophylactic treatment of these conditions.

[0586] The compounds described herein have the advantage that they may be more efficacious, be less toxic, be more selective, be more potent, produce fewer side effects, be more easily absorbed, and / or have a better pharmacokinetic profile (e.g. higher oral bioavailability and / or lower clearance), than compounds known in the prior art.

[0587] COMBINATION THERAPY

[0588] The compounds of Formula (I), or a pharmaceutically acceptable salt thereof, may also be administered in conjunction with other compounds used for the treatment of the above conditions.

[0589] In another embodiment, there is a combination therapy wherein a compound of Formula (I), or a pharmaceutically acceptable salt thereof, and a second active ingredient are administered concurrently, sequentially or in admixture, for the treatment of one or more of the conditions listed above. Such a combination may be used in combination with one or more further active ingredients.

[0590] A compound of Formula (I), or a pharmaceutically acceptable salt thereof, could be used in combination with check point blockade PD-(L)1 axis or with CTLA4 in efforts to expand response rates to check point blockade. Primary or secondary resistance to check point blockade may be potential indications for a compound of Formula (I), or a pharmaceutically acceptable salt thereof. Additional combinations may include radiation, chemotherapy, surgery, tumour targeted agents or other immune targeted agents.

[0591] When used in a combination therapy, it is contemplated that the compounds of Formula (I) or pharmaceutically acceptable salts thereof and the other active ingredients may be administered in a single composition, completely separate compositions, or a combination thereof. It also is contemplated that the active ingredients may be administered concurrently, simultaneously, sequentially, or separately. The particular composition(s) and dosing frequency(ies) of the combination therapy will depend on a variety of factors, including, for example, the route of administration, the condition being treated, the species of the patient, any potential interactions between the active ingredients when combined into a single composition, any interactions between the active ingredients when they are administered to the animal patient, and various other factors known to physicians (in the context of human patients), veterinarians (in the context of non-human patients), and others skilled in the art.

[0592] PHARMACEUTICAL COMPOSITIONS

[0593] There is provided a method of treatment of a condition where inhibition of HPK1 is required, which method comprises administration of a therapeutically effective amount of a compound of Formula (I) to a person suffering from, or susceptible to, such a condition.

[0594] The compounds of Formula (I) will normally be administered via the oral, topical, parenteral, intravenous, intramuscular, subcutaneous or in other injectable ways, buccal, rectal, vaginal, transdermal and / or nasal route and / or via inhalation, in the form of pharmaceutical preparations comprising the active ingredient or a pharmaceutically acceptable salt thereof, in a pharmaceutically acceptable dosage form. Depending upon the disorder and patient to be treated and the route of administration, the compositions may be administered at varying doses. Conventional procedures for the selection and preparation of suitable pharmaceutical formulations are described in, for example, Pharmaceuticals - The

[0595] Science of Dosage Form Designs , M. E. Aulton, Churchill Livingstone, 2ndEd. 2002.

[0596] Suitable daily doses of the compounds of Formula (I) in therapeutical treatment of humans are about 0.0001-100 mg / kg body weight, preferably 0.01-10 mg / kg body weight.

[0597] Oral formulations are preferred, particularly tablets or capsules which may be formulated by methods known to those skilled in the art to provide doses of the active compound in the range of 0.007 mg to 700 mg. The optimum dosage and frequency of administration will depend on the particular condition being treated and its severity; the species of the patient; the age, sex, size and weight, diet, and general physical condition of the particular patient; brain / body weight ratio; other medication the patient may be taking; the route of administration; the formulation; and various other factors known to physicians and others skilled in the art.

[0598] According to a further aspect there is thus provided a pharmaceutical formulation comprising a compound of Formula (I), or pharmaceutically acceptable derivatives thereof, in admixture with a pharmaceutically acceptable adjuvant, diluent and / or carrier.

[0599] The compounds of Formula (I) may be present in the pharmaceutical formulation in a concentration from 0.1 to 99.5%, such as from 0.5 to 95%, by weight of the total formulation.

[0600] The protection and deprotection of functional groups is described in Protective Groups in Organic Synthesis , 4 th Ed, T.W. Greene and P.G.M. Wuts, Wiley-Interscience (2006) and Protecting Groups , 3rdEd, P.J. Kocienski, Georg Thieme Verlag (2005).

[0601] A further embodiment encompasses pharmaceutically acceptable salts of the compounds of Formula (I).

[0602] A salt of a compound of Formula (I) may be advantageous due to one or more of its chemical or physical properties, such as stability in differing temperatures and humidities, or a desirable solubility in H2O, oil, or other solvent. In some instances, a salt may be used to aid in the isolation or purification of the compound. In some embodiments (particularly where the salt is intended for administration to an animal, e.g. a human, or is a reagent for use in making a compound or salt intended for administration to an animal), the salt is pharmaceutically acceptable.

[0603] The term “pharmaceutically acceptable” is used to characterize a moiety (e.g. a salt, dosage form, or excipient) as being appropriate for use in accordance with sound medical judgment. In general, a pharmaceutically acceptable moiety has one or more benefits that outweigh any deleterious effect that the moiety may have. Deleterious effects may include, for example, excessive toxicity, irritation, allergic response, and other problems and complications. Where the compound is sufficiently basic, pharmaceutically acceptable salts include, but are not limited to, inorganic or organic acid addition salts.

[0604] For reviews on suitable salts, see Berge et al ., . / . Pharm. Sci., 1977, 66, 1-19 or Handbook of Pharmaceutical Salts: Properties, selection and use, P.H. Stahl, P.G. Vermuth, IUPAC, Wiley-VCH, 2002.

[0605] Where an acid co-former is a solid at r.t. and there is no or only partial proton transfer between the compound of Formula (I) and such an acid co-former, a co-crystal of the co- former and compound of Formula (I) may result rather than a salt. All such co-crystal forms of the compound of Formula (I) are encompassed herein.

[0606] It is also to be understood that certain compounds of Formula (I) may exist in solvated form, e.g. hydrates, including solvates of a pharmaceutically acceptable salt of a compound of Formula (I).

[0607] In a further embodiment, certain compounds of Formula (I) may exist as racemates and racemic mixtures, single enantiomers, individual diastereomers and diastereomeric mixtures. Certain compounds of Formula (I) may also contain linkages (e.g. carbon-carbon bonds, carbon-nitrogen bonds such as amide bonds) wherein bond rotation is restricted about that particular linkage, e.g. restriction resulting from the presence of a ring bond or double bond. Stereoisomers may be separated using conventional techniques, e.g. chromatography or fractional crystallization, or the stereoisomers may be made by stereoselective synthesis.

[0608] In a further embodiment, the compounds of Formula (I) encompass any isotopically-labelled (or “radio-labelled”) derivatives of a compound of Formula (I). Such a derivative is a derivative of a compound of Formula (I) wherein one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature. Examples of isotopes that may be incorporated include ¾ (also written as “D” for deuterium).

[0609] In a further embodiment, the compounds of Formula (I) may be administered in the form of a prodrug which is broken down in the human or animal body to give a compound of the Formula (I).

[0610] Various forms of prodrugs are known in the art. For examples of prodrug derivatives, see: Nature Reviews Drug Discovery 2008, 7, 255 and references cited therein.

[0611] Intermediate compounds may also exist in enantiomeric forms and may be used as purified enantiomers, diastereomers, racemates or mixtures. PHARMACOLOGICAL ACTIVITY ASSAY DESCRIPTIONS

[0612] HPK1, GLK, and LCK IC50 assays: Activity of purified N-terminal GST-tagged, recombinant, human HPK1, GLK, and LCK enzymes expressed in insect cells (HPK1: amino acids 1-346, ThermoFisher Scientific, #PV6356, Carlsbad, CA; GLK: amino acids 1-380, ThermoFisher Scientific, #PV6351, Carlsbad, CA; LCK: full length, Abeam, #ab79626, Cambridge, MA) was determined in-vitro using ADP-Glo Max Assay (Promega, #V7002, Madison, WI), a luminescent ADP detection assay, by quantifying the amount of ADP produced in a kinase reaction.

[0613] The luminescent signal generated is proportional to the ADP concentration produced in a kinase assay in the presence and absence of the compound(s) and is correlated with the kinase activity. Two microlitres (mΐ) of enzyme mix consisting of 10 nM HPK1, 30 nM GLK, or 2 nM LCK in lx reaction buffer (50 mM HEPES (pH7.2), 1 mM DL-Dithiothreitol (DTT), 0.005% (vol / vol) Brij35, 20 mM MgC12) was spotted into Greiner 384-well low volume plate with 0.1 pi of compound, which was dosed at 100, 31.25, 12.5, 3.19, 1, 0.32, 0.1, 0.032, 0.01 and 0.003 mM of final test concentrations and preincubated for 30 minutes at room temperature. Enzymatic reactions were initiated with 2 mΐ of peptide substrate / ATP mix (for HPK1: 10 mM LRRKtide (RLGRDKYKTLRQIRQ-amide; Cambridge Research Biochemicals, Billingham, UK), 30 mM ATP; for GLK: 14 mM LRRKtide, 60 mM ATP; for LCK: 100 μMLCKtide (EQEDEDEPEGIY GVLE-amide; Intonation, Boston, MA), 50 mM ATP) in lx reaction buffer and incubated at room temperature for 60 minutes. 4 mΐ ADP-Glo Reagent was added to terminate the reactions and deplete the remaining ATP and incubated at room temperature for 60 minutes. Finally, 8 mΐ ADP-Glo Max Detection Reagent was added to simultaneously convert ADP to ATP and incubated at room temperature for 60 minutes. The newly synthesized ATP is converted to light using a luciferase / luciferin reaction. Luminescence was read by PHERAstar FSX plate reader (BMG LAB TECH, Cary, NC) and the data was captured by PHERAstar FSX MARS data analysis software. IC50 values were processed using GeneData Screener (GeneData AG, Basel, Switzerland).

[0628] Method

[0629] Cryo-preserved human CD3+ T cells are recovered in warm T cell media overnight. Recovered T cells are seeded at 70000 cells per well in a 384-well Black / Clear Round Bottom Ultra-Low Attachment Spheroid Microplate (Corning 3830). Compounds in a assay ready 384-well plate (Greiner 781280) are added to the seeded T cells using a Bravo liquid handler. T cells are then left in a humidified incubator at 37°C for 1 hour. At the end of incubation, the cells are transferred to a 384-well flat bottom plate (Greiner 781090) coated with anti-CD3 antibody (5ug / mL anti-CD3 in PBS, overnight incubation at 4 °C). Anti-CD28 antibody in T cell media is also added to the cells by Bravo liquid handler at 5ug / mL or lug / mL in a donor dependent manner. T cells are then incubated in a humidified incubator at 37°C for 4 hours. Cell culture supernatant is collected using a Bravo liquid handler in a v-bottom 384 well plate (Greiner 781280) after the 4-hour incubation. IL2 is detected using a IL2 MultiCyt® QBeads® kit on an iQue Screener flow cytometer (Sartorius). Briefly, capture beads are diluted by 50x in the supplied capture bead diluent. lOul per well diluted capture beads is added to each well of a v- bottom 384 well plate (Greiner 781280) using a ThermoFisher multichannel pipette. Using a Bravo liquid handler, lOul cell culture supernatant is transferred to the v-bottom plate with diluted capture beads. The plate is then sealed in foil and incubate at room temperature on a plate shaker set to 900rpm for 1 hour. At the end of incubation, 10μL per well of the supplied detection reagent is added to the wells using a ThermoFisher multichannel pipette. The plate is then sealed in foil and incubate again at room temperature on a plate shaker set to 900rpm for 2 hours before detection by iQue Screener. iQue Screener flow cytometer uses pre-configured analysis template supplied with the IL2 MultiCyt® QBeads® kit to detect IL2 in each sample wells.

For acid analysis the column used was Waters Acquity HSS T3, 1.8 micron, 2.1 mm x 30 mm; for base analysis the column used was Waters Acquity BEH Cl 8, 1.7 micron, 2.1 mm x 30mm; or 2) Shimadzu LCMS-2020 with electrospray ionization in positive ion detection mode with 20ADXR pump, SIL-20ACXR autosampler, CTO-20AC column oven, M20A PDA detector and LCMS 2020 MS detector, using one of three conditions: a) Halo C18 column (2.0 micron, 3 mm x30 mm) in combination with a gradient (5-100% B in 1.2 minutes) of water and formic acid (0.1%) (A) and acetonitrile and formic acid (0.1%) (B) at a flow rate of 1.5 mL / min; b) Halo C18 column (2.0 micron, 3 mm x 30 mm) in combination with a gradient (5-100% B in 1.2 minutes) of water and trifluoroacetic acid (0.05%) (A) and acetonitrile and trifluoroacetic acid (0.05%) at a flow rate of 1.5 mL / min; or c) Poroshell HPH C18 column (2.7 micron, 3 mm x 50 mm) in combination with a gradient (10-95% B in 2 minutes) of aqueous 46 mM ammonium carbonate / ammonia buffer at pH 10 (A) and acetonitrile (B) at a flow rate of 1.2 mL / min.

[0679] Photoredox chemistry was carried out using a 34 W Kessil HI 50 blue LED lamp (440 nm) as light source, in a HepatoChem EvoluChem™ PhotoRedOx reaction apparatus. Optical rotation data were taken on a Jasco P-2000 polarimeter, using a 100 mm path length, 0.40 w / v% solutions of compound in DMSO, with the sodium D line (589 nm), at 25 degrees Celsius.

[0680] The X-ray diffraction analysis was performed according to standard methods, which can be found in e.g. Kitaigorodsky, A.I. (1973), Molecular Crystals and Molecules, Academic Press, New York; Bunn, C.W. (1948), Chemical Crystallography, Clarendon Press, London; or Klug, H.P. & Alexander, L.E. (1974), X-ray Diffraction Procedures, John Wiley & Sons, New York. Samples were mounted on single silicon crystal (SSC) wafer mounts and powder X-ray diffraction was recorded with a PANalytical X’Pert PRO (reflection geometry, wavelength of X-rays 1.5418 A nickel-filtered Cu radiation, Voltage 45 kV, filament emission 40 mA). Automatic variable divergence and anti scatter slits were used and the samples were rotated during measurement. Samples were scanned from 2 - 50 °2Theta or 2 - 40 °2Theta using a 0.013° step width and between 44 and 233 seconds count time using a PIXCEL detector (active length 3.35 °2Theta).

[0681] It is known in the art that an X-ray powder diffraction pattern may be obtained which has one or more measurement errors depending on measurement conditions (such as equipment, sample preparation or machine used). In particular, it is generally known that intensities in an X-ray powder diffraction pattern may fluctuate depending on measurement conditions and sample preparation. For example, persons skilled in the art of X-ray powder diffraction will realise that the relative intensities of peaks may vary according to the orientation of the sample under test and on the type and setting of the instrument used. The skilled person will also realise that the position of reflections can be affected by the precise height at which the sample sits in the diffractometer and the zero calibration of the diffractometer. The surface planarity of the sample may also have a small effect. Hence a person skilled in the art will appreciate that the diffraction pattern data presented herein is not to be construed as absolute and any crystalline form that provides a power diffraction pattern substantially identical to those disclosed herein fall within the scope of the present disclosure (for further information see Jenkins, R & Snyder, R.L. ‘Introduction to X-Ray Powder Diffractometry’ John Wiley & Sons, 1996). Generally, a measurement error of a diffraction angle in an X-ray powder diffractogram may be approximately plus or minus 0.1° 2-theta, and such a degree of a measurement error should be taken into account when considering the X-ray powder diffraction data. Furthermore, it should be understood that intensities might fluctuate depending on experimental conditions and sample preparation (e.g. preferred orientation). The following definitions have been used for the relative intensity (%): 81 - 100%, vs (very strong); 41 - 80%, str (strong); 21 - 40%, med (medium); 10 - 20%, w (weak); 1 - 9%, vw (very weak).
