[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 250,883, filed on September 30, 2021, the entire contents of which are incorporated herein by reference for all purposes.
[0003] STATEMENT REGARDING RIGHTS TO INVENTS RESULTING FROM FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
[0004] not applicable.
[0005] Appendix to a "Sequence Listing", table or computer program listing submitted on a compact disc
[0006] not applicable. Background Art
[0007] The mitogen-activated protein kinase (MAPK) signaling pathway plays a key role in regulating a variety of cellular activities, including cell proliferation, survival, differentiation, and motility. The MAPK signaling pathway is mediated by receptor tyrosine kinases (RTKs). More than one-third of all malignancies present with dysregulation of the MAPK pathway. The classical MAPK pathway consists of Ras (a family of related proteins expressed in all animal cell lineages and organs), Raf (a family of three serine / threonine-specific protein kinases associated with retroviral oncogenes), MEK (mitogen-activated protein kinase kinase), and ERK (extracellular signal-regulated kinase), which sequentially transmit proliferative signals generated by cell surface receptors to the nucleus via cytoplasmic signal transduction. RTKs and components of the MAPK pathway, such as RAS and RAF, are frequently activated by mutations in human cancers, resulting in constitutive pathway activation. Several RTK and MAPK pathway inhibitors, including epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), and MAPK inhibitors, have been approved for the treatment of solid tumors where activation of these pathways is an oncogenic driver.
[0008] KRAS (Kirsten rat sarcoma 2 viral oncogene homolog) is part of the RAS / MAPK pathway. KRAS is one of the most prevalent oncogenes in a variety of human cancers. Despite compelling evidence that oncogenic KRAS drives tumorigenesis, efforts to target mutant KRAS have stalled for years. Recently, progress has been made in the development of treatments for cancers characterized by KRAS with a G12C mutation, which is present in approximately 15% of lung adenocarcinomas and 0%-8% of other cancers. Results from early clinical trials suggest that many cancer patients in this subgroup could benefit significantly from these new therapies. The first KRAS G12C inhibitor, sotolagasib, has been granted accelerated approval by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with locally advanced or metastatic NSCLC with a KRASG12C mutation, as determined by an FDA-approved test, who have previously received at least one systemic therapy. Another KRAS G12C inhibitor, adagracib, has been granted FDA Breakthrough Therapy designation for the same indication. Other KRAS G12C inhibitors are also under investigation.
[0009] Despite the progress made by RTK inhibitors and MAPK pathway inhibitors, resistance to these pathway inhibitors has been observed in both clinical and nonclinical studies. Such resistance may be driven by activation or upregulation of other components of the pathway. Therefore, monotherapy containing RTK and MAPK pathway inhibitors may not be sufficient to treat tumors that have developed or are likely to develop resistance to approved pathway inhibitors.
[0010] Non-receptor protein-tyrosine phosphatase type 11 (PTPN11, also known as Src homology-2 phosphatase (SHP2)) is a non-receptor protein tyrosine phosphatase encoded by the PTPN11 gene. SHP2 plays a key role in the RTK-mediated MAPK signal transduction pathway. The PTP contains two tandem Src homology-2 (SH2) domains, which serve as the phosphotyrosine binding domain, the catalytic domain, and the C-terminal tail. In the basal state, the protein usually exists in an inactive, self-inhibited conformation, in which the N-terminal SH2 domain blocks the active site. When stimulated by cytokine-mediated signal transduction and growth factor binding of phosphorylated proteins to the SH2 domain, autoinhibition is relieved, making the active site available for dephosphorylation of PTPN11 substrates (MG Mohl, BG Neel, Curr. Opin. Genetics Dev. 2007, 17, 23-30. KS Grossmann, Adv. Cancer Res. 2010, 106, 53-89. WQ Huang et al., Curr. Cancer Drug Targets 2014, 14, 567-588. C. Gordon et al., Cancer Metastasis Rev. 2008, 27, 179-192.).
[0011] Germline and somatic mutations in PTPN11 have been reported in several human diseases, resulting in gain of function of catalytic activity, including Noonan syndrome and Leopard syndrome; and a variety of cancers, such as juvenile myelomonocytic leukemia, neuroblastoma, myelodysplastic syndrome, B-cell acute lymphoblastic leukemia / lymphoma, melanoma, acute myeloid leukemia, and breast, lung and colon cancer (MG Mohl, BG Neel, Curr. Opin. Genetics Dev. 2007, 17, 23-30). Recent studies have shown that single PTPN11 mutations can induce Noonan syndrome, JMML-like myeloproliferative disease and acute leukemia in mice. These mutations disrupt the autoinhibition between the N-SH2 domain and the catalytic site, allowing the substrate to constitutively enter the catalytic site of the enzyme (E. Darian et al., Proteins, 2011, 79, 1573-1588. ZH Yu et al., JBC, 2013, 288, 10472, W Qiu et al., BMC Struct. Biol. 2014, 14, 10).
[0012] PTPN11 is widely expressed in most tissues and plays a regulatory role in various cell signaling events that are essential for a variety of cellular functions including proliferation, differentiation, cell cycle maintenance, epithelial-mesenchymal transition (EMT), mitogenic activation, metabolic control, transcriptional regulation, and cell migration through multiple signaling pathways including the Ras-MAPK, JAK-STAT, or P13K-AKT pathways (Tajan, M. et al., Eur. J. Medical Genetics, 2015, 58, 509-525. Prahallad, A. et al., Cell Reports, 2015, 12, 1978-1985).
[0013] In addition, increasing evidence suggests that PTPN11 / SHP2 is associated with immune escape during tumorigenesis. Therefore, SHP2 inhibitors can stimulate the immune response of cancer patients (Cancer Res. 2015 Feb 1; 75(3): 508-18. T Yokosuka T, J Exp Med. 2012, 209(6), 1201. S Amarnath Sci Transl Med. 2011, 3, 111ra120. T Okazaki, PNAS 2001, 98: 24, 13866-71).
[0014] Substituted pyrimidine-4(3H)-one compounds refer to a class of compounds having inhibitory activity against PTPN11 / SHP2, as disclosed in International Patent Application No. PCT / US2019 / 045903 filed on August 9, 2019, and are represented by the following formula:
[0015]
[0016] or a pharmaceutically acceptable salt, hydrate, solvate, stereoisomer, conformer, tautomer or combination thereof, wherein subscripts a and b, Y1, Y2, R1, R2, R3, R4, R5, R6, R7, R8, R9, R 10 , R 11 and R 13 As provided in PCT / US2019 / 045903, the entire contents of which are incorporated herein for all purposes. In particular, the substituted pyrimidin-4(3H)-one compounds are represented by formula (I):
[0017]
[0018] Or a pharmaceutically acceptable salt, hydrate, solvate, stereoisomer, conformational isomer, tautomer or combination thereof. In certain embodiments, the compound of formula (I) is compound (10b), represented by the following formula:
[0019]
[0020] Its name is 6-((3S,4S)-4-amino-3-methyl-2-oxa-8-oxaspiro[4.5]dec-8-yl)-3-(Ra)-(2,3-dichlorophenyl)-2,5-dimethylpyrimidin-4(3H)-one.
[0021] The compound of formula (I) (particularly the compound of formula (10b)) is a potent, selective, orally active allosteric inhibitor of Src homology-2 phosphatase (SHP2) (also known as protein tyrosine phosphatase non-receptor type 11 (PTPN11)), which is a tyrosine phosphatase that plays a key role in the receptor tyrosine kinase (RTK)-mediated mitogen-activated protein kinase (MAPK) signal transduction pathway (Matozaki, 2009). The key components of the MAPK pathway include small GTPase RAS, serine / threonine-protein kinase RAF, mitogen-activated protein kinase (MEK) and extracellular signal-activated kinase (ERK). In cells, SHP2 binds to phosphorylated tyrosine residues in the intracellular domain of RTK (such as epidermal growth factor receptor (EGFR)), thereby leading to the activation of the downstream MAPK signal transduction pathway.
[0022] Because cancers may be resistant or develop resistance to RTK and MAPK pathway inhibitors, including KRAS G12C inhibitors, there remains a need for effective and safe therapeutic agents for treating cancer, including agents that can be used in combination. Summary of the invention

"Cancer resistant to KRAS G12C inhibitors" and / or "KRAS G12C-positive cancer resistant to KRAS G12C inhibitors" refers to a cancer or tumor that has failed to respond favorably to treatment with a previous KRASG12C inhibitor, or alternatively has recurred or relapsed after a favorable response to a KRAS G12C inhibitor.
[0078] As used herein, "combined therapeutically effective amount" means an amount of the therapeutic agents that, when administered separately (in a time-sequentially staggered manner, particularly in a sequentially specific manner) to a warm-blooded animal, especially a human being, shows an (additive, but preferably synergistic) interaction (combined therapeutic effect). Whether this is the case can be determined by following blood levels, indicating that at least at certain time intervals, both compounds are present in the blood of the person being treated.
[0079] As used herein, "synergistic effect" refers to at least two therapeutic agents: a PTPN11 inhibitor as defined herein; and a KRAS G12C inhibitor as defined herein that has an effect greater than the simple addition of the effects of the various drugs administered alone. The effect can be, for example, slowing the progression of symptoms of a proliferative disease (such as cancer, particularly lung cancer (e.g., non-small cell lung cancer)) or its symptoms. Similarly, a "synergistically effective amount" refers to the amount required to obtain a synergistic effect.
[0080] "A", "an" or "a(n)" when used herein to refer to a group of substituents or "substituents" means at least one. For example, when a compound is substituted with "an" alkyl or aryl group, the compound is substituted with at least one alkyl group and / or at least one aryl group, wherein each alkyl group and / or aryl group is optionally different. In another example, when a compound is substituted with "a" substituent group, the compound is substituted with at least one substituent group, wherein each substituent group is optionally different.

[0216] IV. Composition
[0217] Compositions of compounds of formula (I) or (10b)
[0218] The oral dosage form comprising the compound of formula (I) or (10b) can be any oral dosage form, which comprises one or more pharmaceutically acceptable carriers and / or excipients. Oral preparations include tablets, pills, powders, dragees, capsules, liquids, lozenges, cachets, gels, syrups, slurries, suspensions, etc., which are suitable for patient ingestion.
[0219] For preparing oral dosage forms comprising a compound of formula (I) or (10b), a pharmaceutically acceptable carrier can be a solid or a liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also serve as a diluent, flavoring agent, binder, preservative, tablet disintegrating agent, or encapsulating material. Details of formulation and administration techniques are described in detail in the scientific and patent literature, see, for example, the latest edition of Remington's Pharmaceutical Sciences, Maack Publishing Co, Easton PA ("Remington's").
[0220] In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active ingredient. In tablets, the active ingredient is mixed with the carrier having the necessary binding properties in suitable proportions and prepared in the shape and size desired.
[0221] Powders, capsules and tablets preferably contain from 5% to 70% of the active pharmaceutical ingredient (e.g., a compound of formula (I) or (10b)), or about 10% to about 70% of the active pharmaceutical ingredient. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, low melting wax, cocoa butter, and the like. The term "preparation" is intended to include the formulation of the active compound and an encapsulating material as a carrier, providing a capsule in which the active ingredient is surrounded by a carrier with or without other excipients, thereby combining with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets and lozenges can be used as solid dosage forms suitable for oral administration.
[0222] Suitable solid excipients include, but are not limited to, magnesium carbonate; magnesium stearate; talc; pectin; dextrin; starch; tragacanth; low melting wax; cocoa butter; carbohydrates; sugars, including but not limited to lactose, sucrose, mannitol or sorbitol, starch from corn, wheat, rice, potato or other plants; celluloses, such as methylcellulose, hydroxypropylmethylcellulose or sodium carboxymethylcellulose; and gums, including acacia and tragacanth; and proteins, including but not limited to gelatin and collagen. If desired, disintegrating agents or fluxing agents may be added, such as cross-linked polyvinyl pyrrolidone, agar, alginic acid or its salt, such as sodium alginate.
[0223] The dragee core has a suitable coating, such as a concentrated sugar solution, which may also contain gum arabic, talc, polyvinyl pyrrolidone, carbomer gel, polyethylene glycol and / or titanium dioxide, lacquer solution and a suitable organic solvent or solvent mixture. Dyes or pigments may be added to the tablet or dragee coating for product identification or to characterize the amount (i.e., dosage) of the active compound. The pharmaceutical preparation in dosage form may also be used orally, for example, using push-fit capsules made of gelatin, and soft sealed capsules made of gelatin and coatings such as glycerol or sorbitol. Push-fit capsules may contain active pharmaceutical ingredients mixed with fillers or binders (such as lactose or starch), lubricants (such as talc or magnesium stearate) and optionally selected stabilizers. In soft capsules, the active pharmaceutical ingredient may be dissolved or suspended in a suitable liquid, such as a fatty oil, liquid paraffin or liquid polyethylene glycol, with or without a stabilizer.
[0224] To prepare suppositories, a low melting wax such as a mixture of fatty acid glycerides or cocoa butter is first melted and the active drug ingredient is dispersed uniformly therein by stirring. The molten homogeneous mixture is then poured into conveniently sized molds, allowed to cool, and thereby to solidify.

[0351] Cell line: NCI-H358 cell line was purchased from ATCC. It is a human NSCLC cell line carrying a heterozygous mutation of KRAS G12C. Cells were cultured in RPMI 1640 containing glutamine (ThermoFisher #22400-089) + 10% fetal bovine serum (FBS, Thermo Fisher #10099-141) in a 37°C tissue culture incubator (Thermo Fisher) containing 5% CO2.
[0352] Test animals: Female NOD / SCID mice (Beijing Anikeeper Biotech Co., Ltd) were used in this experiment. The animals were 6 to 8 weeks old at the time of xenograft implantation. The protocol involving the care and use of animals in this study and any amendments or procedures were reviewed and approved by the Institutional Animal Care and Use Committee (IACUC) of Crown Bioscience Ltd. before implementation. During the study, animal care and use were performed in accordance with the regulations of the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC).
[0353] All mice were housed in an AAALAC-accredited animal research facility at the Light Muller Building, Changping Sector of Zhongguancun Scientific Park, No. 21 Huoju Road, Changping District, Beijing, China. All animals were maintained under veterinary supervision and care at an animal facility that oversees a comprehensive and well-executed health surveillance program.
[0354] Mice were housed in polysulfone IVC cages (325 mm × 210 mm × 180 mm) with a maximum of five animals, free access to food and water, and 12-hour light and dark alternation. All animals were fed with irradiated standard rodent diet-rat and mouse growth and breeding feed (Beijing KeaoXieli Feed Co., LTD) freely. Mice were monitored daily and cages were changed every other week.
[0355] B. Experimental Procedure
[0356] Formulation: Formula (10b) was prepared in 0.5% methylcellulose. To prepare a 0.5% methylcellulose solution, methylcellulose powder (400 cP, Sigma #M0262) was added to heated 80°C sterile water. The solution was incubated at 80°C with stirring for 3-4 hours, followed by incubation at 4°C with continuous stirring for 18 hours. After adjusting the final volume with sterile H2O, the solution was stirred for another 30 min at 4°C and then filtered using a 0.45 μM sterile filter. The prepared 0.5% methylcellulose solution was stored at 4°C for future use.
[0357] In order to prepare the administration suspension of formula (10b) in 0.5% methylcellulose, the compound weighed is placed in a glass vial, and 0.5% methylcellulose solution is added to the vial with a syringe. After vortexing for 30 seconds, the vial is ultrasonicated for about 20 minutes at room temperature on a "high" setting in a water bath sonicator (Shanghai Kudos Ultrasonic Instrument Co., LTD, model SK2510HP), until an off-white suspension without visible solids is obtained. The administration suspension prepared is stored at 4 ° C, while stirring continuously and gently. Fresh administration suspension is prepared once a week.
[0358] Compound A was prepared in Labrasol (Gattefosse #3074). To prepare the Compound A dosing solution, the weighed compound was placed in a glass vial, and Labrasol was added to the vial. The mixture was vortexed for 30 seconds and sonicated for about 5 min in a water bath sonicator (Shanghai Kudos Ultrasonic Instrument Co., LTD, model SK2510HP) until a light yellow solution was obtained. The dosing solution was stored at 4 ° C while stirring gently and continuously. Fresh dosing solutions were prepared once a week. Immediately before the administration of Compound A to the animals, the dosing solution was mixed with an equal volume of sterile ddH2O, vortexed, and then incubated at room temperature for 10 min, at which time a uniform solution was formed and used for dosing mice. The diluted dosing solution was used within one hour after adding water.
[0359] In vivo modeling, treatment and data analysis: For xenograft studies with NCI-H358 cells, 5 million cells with 50% Matrigel (BD bioscience #356234) in sterile PBS (Hyclone Laboratories #SH30256.01) were injected subcutaneously into the right flank of female 6-8 week old NOD / SCID mice (Beijing Anikeeper Biotech Co., Ltd). Tumor size was measured with a caliper and the standard formula was used: length x width 2 / 2, where length and width are the long and short diameters of the tumor, respectively.
[0360] When the average tumor volume reaches 250 mm 3 When, based on tumor volume and body weight, mice are randomly grouped into 8 groups. " Distribution of Matching " method / " Stratification " method based on StudyDirector software version 3.1.399.19 (StudyLog) is randomly grouped. Then, as shown below, by oral gavage (PO), mice vehicle, a single compound under one of three dosing levels (100mg / kg QD, 30mg / kg QD and 10mg / kg QD), a single formula (10b) or a combination of two compounds under one of two dosing levels (100mg / kg QD and 50mg / kg QD) are used. Formula (10b) is used in the morning and compound A is used in the afternoon, wherein the morning and afternoon dosing intervals are 6 hours.

[0362] Dosing was started about 2 weeks after subcutaneous implantation of tumor cells. The dosing volume of formula (10b) is 5mL / kg, and the dosing volume of compound A is 6mL / kg, and is adjusted based on the weight of a single mouse measured once every two weeks. Tumor volume was measured twice a week. Body weight and tumor volume were collected using StudyDirector software version 3.1.399.19 (StudyLog). 21 days after administration (all dosing levels, except 10mg / kg formula (10b)) or 29 days (10mg / kg formula (10b)), according to the blood collection method described below, 2 hours after the last dose of compound A (8 hours after the last dose of formula (10b)) plasma samples were collected.
[0363] Data were analyzed using Microsoft Excel and GraphPad Prism 8.0. Day 0 was the day before treatment started. Body weight change and tumor growth inhibition (TGI) were calculated based on the following formulas.
[0364] Weight change% = (BW i -BW0) / BW0*100%
[0365] BW i BW and BW0 are the body weights of individual mice on measurement day 1 and day 0, respectively.
[0366] TGI%=(C i -T i ) / (C i -C0)*100%
[0367] T i and C i are the mean tumor volumes of the treatment group and the vehicle group on the measurement day, respectively; C0 is the mean tumor volume of the vehicle group on day 0.
[0368] Blood collection for pharmacokinetic analysis: Blood from live animals was obtained through the retroorbital sinus for pharmacokinetic (PK) analysis. The mouse was tightly grasped behind the ear and gently rotated to one side so that a disposable sterile capillary was inserted behind the eyeball and gently rotated to destroy the sinus cavity. The blood flowed through the capillary and was directly added to a volume of 100 μL in a K2EDTA tube (Jiangsu KangJianMedical Apparatus Corporation #044022). The blood in the tube was inverted several times to evenly distribute the EDTA. In order to separate plasma, each tube was centrifuged at 8000 rpm for 5 minutes without braking in a desktop centrifuge (Eppendorf, model 5424R). The supernatant (plasma) was carefully transferred to a microcentrifuge tube and placed on dry ice before storage at -80°C.
[0369] LC-MS / MS quantification of Formula (10b) and Compound A in mouse plasma: The concentrations of Formula (10b) and Compound A in mouse plasma were quantified using a validated LC-MS / MS method. For plasma sample analysis, 20 μL of each sample was precipitated with 200 μL of acetonitrile containing glipizide (100 ng / mL) as an internal standard. The suspension was vortexed for 1 min and centrifuged at 4,000 rpm for 10 min, after which 80 μL of the extract was aliquoted for LC-MS / MS analysis. The HPLC-MS / MS was performed on a Shimadzu Nexera UHPLC system in positive mode (ESI +LC-MS / MS analysis was performed on a Sciex 6500TQ-S triple quadrupole mass spectrometer (MS / MS) operated under ). The mass spectrometry source conditions were set as follows: ion spray voltage (5500 V), CAD (8), CUR (35), TEM (450), GS1 (60), GS2 (60), EP (10), CXP (12), CEM (2000); and for formula (10b): DP (40), CE (65), for compound A: DP (40), CE (47), for internal standard: DP (35), CE (20). Formula (10b) and compound A were separated using a Waters X-Bridge BEH C18 column (2.1×50 mm, 1.7 μm) and detected by multiple reaction monitoring transitions (m / z 437.10>186.10 for formula (10b), m / z 561.20>134.20 for compound A, and m / z 446.20>321.10 for internal standard). The injection volume was 2 uL. LC mobile phase A was 0.025% formic acid-water containing 1 mM ammonium acetate, and mobile phase B was 100% methanol containing 5 mM ammonium acetate. The gradient (% B) was 2% (0-0.4 min), 2-65% (0.4-1.7 min), 65-90% (0.7 to 1.3 min), 90% (1.3-1.9 min), 90-2% (1.9 to 1.91 min), 2% (1.91-2.5 min). The flow rate was 0.6 mL / min. The column temperature was 60° C. Under these conditions, the retention time for formula (10b) was 1.42 min, and the retention time for compound A and internal standard was 1.44 min. The method was validated in untreated CD-1 mouse plasma with an analytical range of 3-3,000 nM (for both formula (10b) and compound A).
[0370] C. Results
[0371] Sotolacib (AMG 510) is a KRAS covalent inhibitor that specifically targets the KRAS G12C mutant. It has demonstrated single-agent responses in patients with solid tumors (including NSCLC) carrying the KRAS G12C mutation. In particular, in the CodeBreaK 100 study, the subgroup with NSCLC had a confirmed 32.2% objective response rate (complete or partial response) and 88.1% disease control rate (objective response or stable disease); the median progression-free survival was 6.3 months. Hong et al., N. Engl. J. Med. 2020; 383: 1207-1217. Unbiased functional genomics approaches also identified SHP2 as a weakness under KRASG12C inhibition. KRAS G12C inhibition induces adaptive feedback activation of the MAPK pathway through multiple RTKs, which signal through SHP2. This study was designed to evaluate the effect of the combination of the SHP2 inhibitor formula (10b) and the KRAS G12C inhibitor Compound A in an in vivo human NSCLC tumor model bearing KRAS G12C.
[0372] Combination treatment with formula (10b) and compound A resulted in tumor growth inhibition in a subcutaneous model of NSCLC carrying KRAS G12C: A mouse tumor xenograft model was generated by subcutaneous implantation of NCI-H358 cells carrying KRASG12C, and was used to test the in vivo anti-tumor response of the combination of formula (10b) and compound A. Mice carrying established NCI-H358 subcutaneous tumors were randomly divided into groups and treated with vehicle, compound A alone, formula (10b) alone, or a combination of the two compounds, delivered orally for 21 days. Formula (10b) was administered daily in the morning, and compound A was administered daily in the afternoon, with a 6-hour interval between morning and afternoon dosing. Tumor volume was monitored by caliper once every two weeks, and body weight was recorded. Figures 1A to 1E The data shown in are expressed as mean ± SEM, and for Figure 1B-1E , N = 8 mice / group and for Figure 1A , N=10 mice / group.
[0373] Figure 1A Shown are the mean (+ / -SEM) tumor volumes (mm) of female NOD / SCID mice bearing NCI-H358 tumors following daily oral administration of Formula (10b), Compound A, or a combination of the two test articles from Day 1 to Day 28 at the indicated dose levels. 3 ).
[0374] like Figure 1A , 1BAs shown in Figures 1 and 1D and Tables 1 and 2, treatment with formula (10b) alone inhibited the growth of NCI-H358 tumors in a dose-dependent manner, resulting in 89% and 46% tumor growth inhibition (TGI) at 100 mg / kg QD and 50 mg / kg QD, respectively, on day 21 of the study. Treatment with compound A alone also inhibited NCI-H358 tumor growth in a dose-dependent manner, with tumor regression observed at 100 mg / kg QD, 30 mg / kg QD, and 10 mg / kg QD. Notably, the combination of compound A 10 mg / kg QD and formula (10b) 100 mg / kg QD more potently inhibited tumor growth than single agents, causing tumor regression ( Figure 1A ). It is worth noting that when formula (10b) 100 mg / kg QD is combined with compound A at 30 mg / kg and 100 mg / kg QD ( Figure 1B and Figure 1D ), a significant enhancement of antitumor activity was observed, which may be attributed to the robust single-agent response of Compound A. All dosing conditions were considered well tolerated, as shown by the maintenance of mouse body weight during the study ( Figure 1C and Figure 1E Although random mouse losses were observed in this study, they were not considered treatment-related due to the lack of dose-dependency (Table 3).

[0380] TGI% = (Ci-Ti) / (Ci-C0) * 100%. Ti and Ci are the average tumor volumes of the treatment group and the vehicle group on the measurement day, respectively; C0 represents the average tumor volume of the vehicle group on day 0. For plasma concentrations, data are expressed as mean ± SD. N = 4 mice / group. BQL, below the limit of quantitation (3 nM).
[0381] Pharmacokinetic analysis was performed 2 hours after the last dose of Compound A (8 hours after the last dose of Formula (10b)) (Table 2). 2 hours after the last dose, significant concentrations of Compound A were detected in plasma, with 30 mg / kg producing 2.0 μM and 100 mg / kg producing 8.8 μM. Compound A plasma concentrations were not affected by treatment with Formula (10b). When administered as a single agent (7.5 μM) and in combination with Compound A (5-10 μM), Formula (10b) 100 mg / kg produced similar significant plasma concentrations 8 hours after administration. When administered as a single agent (4.4 μM) and in combination with Compound A (5.5 μM), administration of Formula (10b) 50 mg / kg also produced similar significant plasma concentrations 8 hours after administration. The data indicate that there is no drug-drug interaction between Compound A and Formula (10b) in mice.

[0385] D. Conclusion
[0386] In the NCI-H358 NSCLC xenograft model carrying the KRAS G12C mutation, combined treatment with formula (10b) and compound A robustly inhibited tumor growth. In detail, treatment with compound A 10 mg / kg QD as a single agent caused tumor growth inhibition, and the combination with formula (10b) caused tumor regression. Treatment with higher doses of compound A (30 mg / kg QD or 100 mg / kg QD) as a single agent caused robust tumor regression; the combination with formula (10b) did not significantly further inhibit tumor volume. Treatment with formula (10b) monotherapy at 100 mg / kg QD caused approximate tumor stagnation. All tested treatment conditions were well tolerated in the mouse model.

Sterile deionized water equivalent to 75% v / v of the expected final volume was added under continuous magnetic stirring with a stir bar and stirred at room temperature until completely dissolved. The buffer was then brought to final volume with anhydrous deionized water. A correction factor of 1.025 was applied to the formulation of Formula (10b) to accommodate the purity (97.7%).
[0402] A 10 mg / mL (10.25 mg / mL in the case of a correction factor) working suspension of formula (10b) was prepared and a 100 mg / kg dose was administered to mice by oral gavage at a 10 mL / kg dose volume. To prepare the formula (10b) formulation, the compound was accurately weighed into a glass bottle. The formula (10b) formulation buffer equivalent to 70% v / v of the expected final volume was added to the glass bottle containing the bulk drug and fully mixed for 4 to 9 minutes using a 1 / 4 inch probe until a homogeneous suspension without larger visible aggregates / particles was obtained. The remaining portion of the suspension vehicle was added to the dispersion containing the bulk drug to reach the expected final volume. The suspension was fully mixed for 30 minutes, stored at 4°C for one week, and fully mixed before daily administration and throughout the administration period.
[0403] Sotolacib Formulation: Sotolacib formulation buffer (2% v / v HPMC / 1% v / v Tween 80 in sterile deionized water) was prepared by weighing the required amount of HPMC (Sigma-Aldrich, catalog number H3785) and Tween 80 (Sigma-Aldrich, catalog number P4780) into a glass bottle. Sterile deionized water equivalent to 80% v / v of the expected final volume was added under continuous magnetic stirring with a stir bar and stirred at room temperature until completely dissolved. Then, the buffer was brought to final volume with sterile deionized water.
[0404] 1mg / mL and 10mg / mL of Sotolacib working suspensions were prepared and 10mg / kg and 100mg / kg doses were administered to mice by oral gavage at a 10mL / kg dose volume. To prepare the Sotolacib formulation, the compound was accurately weighed into a glass bottle. The Sotolacib formulation buffer equivalent to the expected final volume of 100% v / v was added to the glass bottle containing the drug substance and mixed thoroughly until a homogeneous suspension without larger visible aggregates / particles was obtained. The suspension was mixed thoroughly and the working suspension was administered as quickly as possible. The suspension was prepared daily and mixed thoroughly before administration and throughout the administration period.
[0405] Tumor and body weight measurements: Tumor volume was measured twice weekly in two dimensions using calipers after randomization, and volume was expressed in mm using the formula 3 Mean: tumor volume = (length x width x width) / 2, wherein length is defined as the longest tumor dimension, and width is defined as the longest tumor dimension perpendicular to the length. Dosing and tumor and body weight measurements were performed in a fume hood. The tumor volume of individual mice in each group (and the average tumor volume (± standard error of the mean (SEM))) were recorded. The tumor growth inhibition (TGI) (indicator of the anti-tumor effect) of each treatment group (T) and control group (C) was calculated using the average tumor volume measurements on day 1 (0) and the indicated measurement day (i), using the formula: TGI (%) = (1-(Ti-T0) / (Ci-C0)) x100. TGI was calculated on the day after the last continuous daily dose (day 29) and reported only when ≤100%. Tumor regression (REG) was also assessed and defined as a tumor with a smaller tumor volume on the indicated study day compared to the first dose on day 1. If TGI>100%, mean tumor regression is reported instead and was calculated by determining the mean percentage of tumor regression on the day following the last consecutive daily dose as indicated compared to the first dose on Day 1.
[0406] Body weight (BW) was also recorded twice a week. Using the body weight on day 1 (0) of the first day of dosing and the body weight on the indicated (i) day after dosing, the following formula was used: BW change (%) = ((BWi / BW0) × 100)-100 to calculate the individual mouse body weight and body weight change expressed as a percentage for each animal. The average body weight change (± SEM) was recorded by group. If >20% of the mice in the group had ≥20% weight loss, or >20% of the mice in the group died spontaneously or had any painful clinical symptoms requiring euthanasia, the treatment was considered to be intolerant.
[0407] Record animal tumor and body weight measurements and use Study Director TM All analyses were performed using GraphPad Prism software (version 9) or calculated from raw data in Microsoft Excel.
[0408] Statistical analysis: Statistical analysis was performed using GraphPad Prism software (version 9). For statistical analysis comparing the vehicle group with all other groups, a two-way repeated measures analysis of variance (ANOVA) was applied within the specified days, followed by a post hoc Tukey multiple comparison test for the mean. For statistical analysis comparing monotherapy and combination groups, a two-way repeated measures ANOVA was performed between the mean of each monotherapy group and the mean of the combination group within the specified days. A p value of less than 0.05 was considered statistically significant.
[0409] Experimental endpoints: Animal health was monitored at least twice a week by behavioral observation and body weight examination. Animals were examined daily for morbidity and mortality following tumor inoculation. During routine monitoring, animals were examined for tumor growth and any effects of treatment on behavior, such as motility, food and water consumption, weight gain / loss, eye / hair roughness, and any other abnormalities.
[0410] The study endpoint was defined as when an animal reached one of the following euthanasia criteria: ≥20% body weight loss relative to day 1 at any time; ≥15% body weight loss relative to day 1 for 72 hours; single tumor volume ≥3000mm 3 , or when the mean tumor volume reaches ≥2000mm 3 All mice in each group were euthanized at 4 dpi. In the NCI-H358 study, animals in all groups were euthanized on day 34 or 35, and in the NCI-H2122 study, animals in all groups were euthanized on day 21 or 22.
[0411] C. Results
[0412] Sotolacib (AMG 510) is a KRAS covalent inhibitor that specifically targets the KRAS G12C mutant. It has demonstrated single-agent responses in patients with solid tumors (including NSCLC) carrying KRAS G12C mutations. In particular, in the CodeBreaK 100 study, the subgroup with NSCLC had a confirmed 32.2% objective response rate (complete or partial response) and 88.1% disease control rate (objective response or stable disease); the median progression-free survival was 6.3 months. Hong et al., N. Engl. J. Med. 2020; 383: 1207-1217. Cell line studies have shown that SHP2 inhibitors increase KRAS-GDP occupancy and enhance the effectiveness of KRAS G12C inhibitors because the current generation of KRASG12C inhibitors only inhibits the GDP-bound form of KRAS G12C. Unbiased functional genomics approaches also identified SHP2 as a weakness under KRAS G12C inhibition. Adding SHP2 inhibitors to therapeutics targeting mutant KRAS G12C can improve effectiveness in several ways. Because mutant KRASG12C maintains a certain degree of cycling between these two states, the GTP-bound form of KRAS G12C can still activate ERK signaling in the presence of sotolacib. SHP2 inhibition reduces the SOS1-dependent GTP load of RAS, which causes elevated RAS-GDP levels and can therefore enhance the effectiveness of sotolacib. In addition, compensatory bypass signaling feedback activation mediated upstream or downstream of the RTK / MAPK pathway has been shown to reduce the effectiveness of KRASG12C inhibitors preclinically and clinically, and SHP2 inhibitors can inhibit this feedback activation.
[0413] SHP2 inhibition may also enhance the antitumor activity of KRAS G12C inhibitors in patients with molecular subtypes with particularly poor outcomes. For example, mutations in the tumor suppressor Kelch-like ECH-associated protein 1 (KEAP 1) are found in approximately 20% of KRAS-mutant SCLCs, and co-mutations of KRAS and KEAP1 are associated with poor prognosis and clinical outcomes.
[0414] Two studies were conducted to determine whether the combination of the SHP2 inhibitor formula (10b) and sotolacib enhanced antitumor activity compared to either agent alone. Studies were conducted using a xenograft model derived from the NSCLC NCI-H358 cell line carrying a KRAS G12C mutation and a xenograft model derived from the NSCLC NCI-H2122 cell line carrying a co-mutation of KRASG12C, KEAP1, and STK11.
[0415] Combination treatment with formula (10b) and sotolacib caused tumor regression in the NCI-H358 subcutaneous xenograft model of NSCLC carrying the KRAS G12C mutation. An in vivo study was conducted to evaluate the effect of the combination of formula (10b) and the KRASG12C inhibitor sotolacib on tumor volume in female NOD / SCID mice carrying the NCI-H358 NSCLC xenograft model derived from a cell line carrying the KRASG12C mutation. Female NOD / SCID mice were subcutaneously implanted with NSCLC NCI-H358 tumor cells. When the tumor reached 60 mm 3 When the average size of the tumor was 100 mg / kg, the mice were randomly divided into treatment groups (n=10 / group) and administered the indicated levels of vehicle, 100 mg / kg formula (10b), 10 mg / kg sotolacib, or a combination of 100 mg / kg formula (10b) and 100 mg / kg sotolacib by oral gavage once a day from day 1 to day 28. The tumor volume of the mice was measured twice a week until day 34, and the results are shown until day 29.
[0416] like Figure 2A As shown in Table 4, the combination of Formula (10b) and Sotolacib showed significantly greater antitumor activity than any of the test subjects as monotherapy. After oral administration of the combination of Formula (10b) (100 mg / kg) and Sotolacib (10 mg / kg) once daily, compared to the two monotherapy groups ( Figure 2A and Table 4), a statistically significant reduction in tumor volume was observed in the combination group, and the average tumor regression on day 29 was significantly increased to 83% (Table 4). The results also showed that both formula (10b) and sotolacib had monotherapy antitumor activity at the tested dose levels. After oral administration of formula (10b) (100 mg / kg) or sotolacib (10 mg / kg) once daily, a statistically significant reduction in tumor volume was observed in both treatment groups compared to the vehicle group ( Figure 2A and Table 4), where the mean tumor regressions on day 29 in the formula (10b) and sotolacib monotherapy groups were 14% and 13%, respectively.

[0419] Abbreviations: ANOVA = analysis of variance; NOD / SCID = non-obese diabetes / severe combined immunodeficiency; n = number; REG = regression; SEM = standard error of the mean.
[0420] Note: Oral dosing was performed daily from day 1 to day 28, and the last tumor measurement was performed on day 34. For statistical analysis, two-way repeated measures ANOVA of group means followed by post hoc Tukey's multiple comparison test was performed from day 5 to day 29 for vehicle group comparison*, and two-way repeated measures ANOVA of monotherapy and combination group means was performed from day 5 to day 29 for combination group comparison**.
[0421] like Figure 2B As shown, in the mouse model, treatment had no effect on body weight and all treatments were well tolerated.
[0422] Combination treatment with formula (10b) and sotolacib caused tumor growth inhibition in the NCI-H2122 subcutaneous xenograft model of NSCLC carrying KRAS G12C, KEAP1 and STK11 co-mutations. In vivo studies were conducted to evaluate the effect of the combination of formula (10b) and the KRASG12C inhibitor sotolacib on tumor volume in BALB / c nude mice in the NCI-H2122 NSCLC xenograft model derived from a cell line carrying KRAS G12C mutations. The model also has several coexisting mutations, including frameshift insertions in KEAP1 (KEAP1A203fs) and frameshift deletions in STK11 (STK11G279fs) that cause loss of function of KEAP1 and STK11. When the tumor reaches 180mm 3 When the average size of the tumor was 100 mg / kg, the mice were randomly divided into treatment groups (n=10 / group) and administered the indicated levels of vehicle, 100 mg / kg Formula (10b), 100 mg / kg Sotolacib, or a combination of 100 mg / kg Formula (10b) and 100 mg / kg Sotolacib by oral gavage once a day from day 1 to day 21. The tumor volume and body weight of the mice were measured twice a week until day 21.
[0423] like Figure 3A As shown in Table 5, the combination of Formula (10b) and Sotolacib showed significantly greater anti-tumor activity than either test substance treatment as a monotherapy. Following oral administration of the combination of Formula (10b) (100 mg / kg) and Sotolacib (100 mg / kg) once daily, a statistically significant reduction in tumor volume ( 0.0447 W / m) was observed in the combination group compared to the two monotherapy groups. Figure 3Aand Table 5), and tumor growth inhibition increased significantly to 96% on day 21 (Table 5). The results also showed that both Formula (10b) and Sotolacib had monotherapy antitumor activity at the tested dose levels. After oral administration of Formula (10b) (100 mg / kg) or Sotolacib (100 mg / kg) once daily, a statistically significant decrease in tumor volume was observed in both treatment groups compared to the vehicle group ( Figure 3A and Table 5), and the tumor growth inhibition on day 21 in the formula (10b) and sotolacib monotherapy groups was 58% and 72%, respectively (Table 5).
[0424] Table 5: Summary of the antitumor activity of formula (10b) and sotolacib as monotherapy and in combination in BALB / c nude mice bearing tumors derived from the NCI-H2122 subcutaneous cell line.
[0425]
[0426] Abbreviations: ANOVA = analysis of variance; BALB = Bagg albino; n = number; SEM = standard error of the mean; TGI = tumor growth inhibition.
[0427] Note: Oral dosing was performed daily from day 1 to day 21, and the last tumor measurement was performed on day 21. For statistical analysis: Two-way repeated measures ANOVA of group means followed by post hoc Tukey's multiple comparison test was performed from day 3 to day 21 for vehicle group comparison*, and two-way repeated measures ANOVA of monotherapy and combination group means was performed from day 3 to day 21 for combination group comparison**.
[0428] like Figure 3B As shown in the mouse model, Sotolacib monotherapy or combination treatment had no effect on body weight, and these treatments were well tolerated. Unexpectedly, several mice in the Formula (10b) monotherapy group had a weight loss of more than 10%, so from day 11 to day 21, the animals in this group were placed on a diet gel ( Figure 3B The reason for this weight loss is unknown and has not been observed in previous studies at this dose level (100 mg / kg). Importantly, Formula (10b) was administered at the same dose level (100 mg / kg) in the combination group of Formula (10b) and Sotolacib, and the combination was well tolerated ( Figure 3B ).
[0429] D. Conclusion
[0430] The results of these two in vivo studies showed that the combination of formula (10b) and sotolacib was well tolerated and showed significant anti-tumor benefit in a mutant KRAS G12C NSCLC NCI-H358 cell line-derived xenograft model and a mutant KRAS G12C and KEAP1A203fs NSCLC NCI-H2122 cell line-derived xenograft model. These in vivo studies support the clinical evaluation of the combination and show that SHP2 inhibition can enhance the response of KRASG12C inhibitors and increase the number of patients who can benefit from the combination of formula (10b) and sotolacib as a potential treatment, these patients have mutant KRASG12C, and with or without co-mutations, such as KEAP1 or STK11.

[0448] A. Due to the coronavirus disease 2019 (COVID-19) pandemic, telephone or video contact visits may be required for safety monitoring, changes in visit schedules, or other appropriate changes in clinical trial conduct. Allowable study days are expected to be specified as best practices; however, adjustments may be made as needed. If necessary, additional changes to the timeline of events will be made and documented in accordance with current FDA guidance (e.g., FDA Guidance for Clinical Trials of Medical Products During the COVID-19 Public Health Emergency).
[0449] B. In each 28-day cycle, the study treatment will be taken orally every 24 hours (± 3 hours). Compound (10b) should be taken before Sotolacib. The day before and on the day of the study visit, the two study treatments should be taken within a 5-minute window unless one of the study treatments is shelved. The study treatment should be taken with about 240mL (8oz) of water after fasting overnight (minimum 8hr), followed by fasting for 2hr after taking the dose. It was opened 1 hour before administration, and water was allowed to be drunk freely. Compound (10b) will be taken QD, combined with Sotolacib QD. Two doses of compound (10b) selected from the dose escalation of Phase 1a will be used for compound (10b) in Phase 1b dose expansion / optimization. The dose can be adjusted based on the SRC decision after reviewing all the data.
[0450] C. Documentation of KRAS G12C mutation confirmed from local or central laboratory testing of tumor or liquid biopsy specimens collected within 2 years prior to screening. Note: KRAS G12C status was determined by a central laboratory, as local laboratory confirmation was not required prior to enrollment.
[0451] D. For Phase 1a: Patients with locally advanced or metastatic solid tumors and KRAS-G12C mutations. For Phase 1b: Patients with locally advanced or metastatic NSCLC and KRAS-G12C mutations who have not been treated with KRAS-G12Ci.
[0452] E. Re-staging scans (CT, MRI, or PET-CT) should be performed at Screening, C3D1 (±7d), and then every 8 weeks (±7d) thereafter until PD. Scans will be performed at the EOT follow-up visit unless performed within 28d of the EOT follow-up visit. Confirmatory scans will also be obtained at least 4 weeks after the initial documented objective response (i.e., PR or CR according to RECIST v1.1). Scans obtained The type was determined by the investigator at their discretion as to whether it was appropriate for the disease. However, the same approach should be used during the duration of the study. All scans will be read locally; in Phase 1b dose expansion / optimization, scans will also be read by blinded independent central review. Patients who discontinue study drug for reasons other than radiological PD will have a radiological assessment during the LTFU period per standard of care imaging, with data reported as they become available until radiological PD is observed (unless consent is withdrawn).
[0453] F. Blood samples will be used to assess relevant tumor markers as needed.

[0467] T. A fresh tumor biopsy should be collected from all patients enrolled in the study, if at all feasible. If a fresh tumor biopsy was not completed during molecular prescreening and is not feasible during screening, an archived tumor biopsy with sufficient tumor for central testing for KRAS mutations, preferably collected within 6 months but no longer than 2 years of enrollment, may be used. Patients may be enrolled even when a tumor biopsy is judged unavailable in consultation with the Medical Monitor in conjunction with the Investigator. Enrollment of patients without tumor biopsy collection will be handled on a case-by-case basis by the Medical Monitor. Please refer to the Laboratory Specimen Manual for details regarding the collection and handling of tumor tissue samples.
[0468] U. If the start of the subsequent cycle is delayed due to the interruption of the simultaneous administration of two study drugs, the weekly assessment should be recorded as an unscheduled visit for the just completed 28-day cycle until the administration of at least one study treatment is resumed. The first day of the next cycle will be the day of restarting the study treatment. If compound (10b) or sotolacib is interrupted for 15 consecutive days, the patient should permanently interrupt both study drugs.

Patients who interrupt treatment because of radioactive PD, and patients who interrupt treatment for reasons other than PD and subsequently have radioactive PD will track survival status and new anticancer therapy information approximately every 3 months (by phone) until EOS. This survival follow-up is also applicable to patients who interrupt study treatment for reasons other than radioactive PD but withdraw consent for further tumor assessment. Survival visits will continue until all patients have interrupted study treatment, died, withdrew consent or lost to follow-up, or until EOS, whichever occurs first. Long-term follow-up will also include collecting disease response and secondary deterioration. If arranged as part of a routine visit, a clinical visit may also replace a long-term visit telephone contact.
[0483] JJ.C1D22 will be a telephone visit during which daily self-administration of study treatment will be reviewed from the patient diary and information on AEs and concomitant medications will be recorded in source documents and transcribed to the CRF.
[0484] KK. Molecular prescreening for KRAS mutations by a CLIA-certified laboratory using appropriate clinically validated and / or FDA-approved tests, if applicable, was performed only if there was no documentation of a KRAS mutation within 2 years prior to screening.

[0509] Any other clinically significant or persistent toxicity of grade ≥ 3 that could be considered a DLT after SRC review.
[0510] Adverse events (AEs)
[0511] An AE is an adverse medical condition or worsening of a pre-existing medical condition in a patient participating in a clinical study, whether or not it is considered to be causally related to the study drug. Therefore, an AE may be any unfavorable and unexpected sign (including abnormal laboratory findings), symptom, or disease (new or worsening). In clinical studies, AEs may include adverse medical conditions that occur at any time, including baseline or washout periods, even when study treatment is not being administered.
[0512] All AEs that occur after the patient receives the first dose of study drug or during participation in the study must be recorded on the appropriate form provided, regardless of whether they are related to the study drug. Evaluate the severity, intensity, and causal relationship of each AE to each study drug or other factors. SAEs should be recorded and reported from the time of informed consent.
[0513] At each visit, patients should be asked in an open-ended manner about their AEs and about the status of any previously reported AEs.
[0514] When possible, the specific disease or condition rather than the individual associated sign or symptom should be identified and recorded on the form by the investigator. If a sign or symptom is observed or reported that is not considered by the investigator to be a component of a specific disease or condition, it should be recorded on the form as a separate AE.
[0515] NOTE: Unexpected worsening or aggravation of the condition / indication under study should be reported as an AE. However, expected day-to-day fluctuations or expected progression of the disease under study (based on the investigator's clinical judgment) are not considered AEs. Disease progression should be recorded on the relevant CRF page. Deaths attributed solely to disease progression should not be reported as SAEs, but all accompanying deaths must be recorded in the CRF.
[0516] Abnormal laboratory results (e.g., clinical chemistry, hematology, and urinalysis), specific studies (e.g., scans, MUGA / ECHO), or other abnormal assessments (e.g., physical examination results, ECG, and vital signs) that are judged by the investigator to be clinically significant, i.e., require further investigation and / or treatment, will be recorded as AEs. Clinically significant abnormal laboratory results, specific studies or other abnormal assessments detected during the study or present at baseline and significantly worsened after exposure to study treatment are reported as AEs. However, clinically significant abnormal laboratory results, specific studies or other abnormal assessments related to the disease being studied should not be reported as AEs unless judged by the investigator to be more severe than expected for the patient's condition or to be present at the start of the study but not to worsen.
[0517] Medical or surgical procedures (e.g., endoscopy, appendectomy) are not AEs; conditions requiring surgery if new or worsened from baseline are AEs. Elective procedures or pre-planned interventions for pre-existing conditions that would not have worsened from the start of the study are also not AEs; pre-existing conditions should be documented as medical history. Hospitalizations for social reasons and / or convenience without adverse medical events are not AEs.
[0518] The investigator is responsible for reviewing all laboratory test results for all patients, including laboratory evaluations performed at outside laboratories, and determining whether they constitute an AE. The investigator will evaluate the outside laboratory test results and determine the clinical significance of any considered AEs. In these cases, the laboratory report should be signed and dated by the investigator.
[0519] Serious Adverse Events (SAEs)
[0520] SAEs are any of the following AEs occurring at any dose regardless of causality:
[0521] Causes death, or death is a consequence of the AE rather than the AE itself, unless the cause of death is unknown, in which case the death should be recorded as an AE.
[0522] Life-threatening
[0523] o Life-threatening means that, in the opinion of the investigator or study sponsor, the patient is at immediate risk of death as a result of the reaction (ie, it does not include reactions that have occurred in a more severe form and are hypothetically likely to cause death).
[0524] · Requires hospitalization of the patient or extension of existing hospitalization.
[0525] o In general, hospitalization refers to the retention (usually involving at least an overnight stay) of a patient in a hospital or emergency room for observation and / or treatment that is not appropriate in a physician's office or outpatient setting.
[0526] o A complication that occurred during hospitalization was an AE. An event was serious if the complication prolonged hospitalization or met any other severity criteria.
[0527] o If an ailment or disease existed prior to the patient's enrollment in the trial, a hospital admission and / or surgical procedure was scheduled during the study period, but was planned before the signing of the ICF, it was not considered an AE, provided that it did not worsen in an unexpected manner during the trial (e.g., surgery was performed earlier than planned).
[0528] · Resulting in permanent or significant disability / incapacity.
[0529] οDisability is defined as a substantial impairment of an individual's ability to carry out normal life functions.
[0530] o The definition is not intended to include relatively minor medically significant experiences that may interfere with or prevent daily functioning but do not constitute a substantial impairment, such as uncomplicated headaches, nausea, vomiting, diarrhea, influenza, and accidental trauma (e.g., a sprained ankle).
[0531] Is a congenital anomaly / birth defect.
[0532] It is a major medical event.
[0533] o A significant medical event is an event that may not result in death, be life-threatening, or require hospitalization, but which may be considered a SAE based on appropriate medical judgment, which may endanger the patient and may require medical or surgical intervention to prevent one of the outcomes listed in the definition for an SAE. Examples of such medical events include allergic bronchospasm requiring intensive treatment in the emergency room or at home, blood dyscrasias or seizures that do not result in hospitalization of the patient, or the development of drug dependence or drug abuse.
[0534] A distinction should be made between the terms “serious” and “severe” as they are not synonymous. The term “severe” is often used to describe the intensity (severity) of a specific event (e.g., mild, moderate, or severe myocardial infarction); however, the event itself may be of relatively minor medical significance (e.g., severe headache). This is different from “serious,” which is based on patient / event outcomes or action criteria generally associated with events that threaten patient life or function. A severe AE does not necessarily need to be considered serious. For example, persistent nausea lasting several hours may be considered severe nausea, but it is not an SAE if the event does not meet the severity criteria. On the other hand, a stroke that results in only mild disability may be considered mild but is defined as an SAE based on the severity criteria described above. Severity (not severity) serves as a guide for defining regulatory reporting obligations.
[0535] Intensity of AE usage
[0536] NCI CTCAE v 5.0 rating available at https: / / ctep.cancer.gov / protocolDevelopment / electronic_applications / docs / CTCAE_v5_Quick_Reference_5x7.pdf, the disclosure of which is incorporated herein by reference in its entirety.
[0537] Administration, Dosing Adjustments, Delays, and Interruptions
[0538] The duration of each treatment cycle will be 28 days, unless an alternative dosing schedule is implemented based on SRC review. In the absence of a reason for interruption of dosing, a new cycle will begin immediately after the completion of the previous cycle. Compound (10b) and sotolacib will be self-administered without interruption, unless 1) there is an AE as described below; 2) the SRC recommends an alternative dosing schedule based on observed safety, tolerability and PK / pharmacodynamic data; or 3) the patient is seen in the outpatient clinic to evaluate AEs, PK sample collection or laboratory evaluation. At such visits, patients will take compound (10b) and sotolacib at the same time in the outpatient clinic as directed by the research staff. For any blood draws performed outside the clinic, patients will take compound (10b) and sotolacib as directed by the research staff and record / provide dosing information. Each dose of compound (10b) should be taken orally once every 24 hours (±3 hours) with approximately 240 mL (8 ounces) of water. Patients should take compound (10b) after fasting overnight (minimum 8 hours), followed by a 2-hour fast after taking the dose. Water is allowed ad libitum except for 1 hour before and after dosing. If a dose is missed, the next dose will be increased without taking into account the missed dose. The patient will take the next regularly scheduled dose at the scheduled time.
[0539] Although sotolacib can be taken with or without food, both study treatments should be taken in the fasting state as described for compound (10b). Compound (10b) should be taken before sotolacib. Both study treatments should be taken within a 5-minute window on the day before and on the day of the study visit.
[0540] If Compound (10b) or Sotolacib was permanently discontinued, the patient had to also discontinue the other study treatment; monotherapy with Compound (10b) or Sotolacib was not permitted in this study.
[0541] Reasons for permanent discontinuation of both study treatments (compound (10b) and sotolacib) included, but were not limited to, the following:
[0542] The patient develops a DLT and is unable to continue with a lower dose of study treatment (as discussed elsewhere in this example);
[0543] Permanent discontinuation of either study treatment for reasons outlined elsewhere for compound (10b) or sotolacib;
[0544] Disease progression as assessed by the investigator according to RECIST v.1.1;
[0545] Risk to patients as judged by the investigator and / or sponsor;
[0546] Severe non-compliance with the regimen as judged by the investigator and / or sponsor;
[0547] The patient is pregnant;
[0548] Patient decision making;
[0549] Initiation of non-study anticancer treatment; and
[0550] Failure to restart treatment within 15 days of dose interruption
[0551] Specific reasons for withdrawal from the study will include the following:
[0552] The patient withdraws consent. The patient is free to withdraw from the study at any time without affecting further treatment;
[0553] Lost to follow-up (defined as no contact after 3 documented telephone attempts followed by 1 attempt via confirmation letter);
[0554] Death due to any cause;
[0555] The sponsor decides to terminate the study: and
[0556] Decision of the researcher.
[0557] For each patient, a maximum of two dose reductions of each oral agent (Compound (10b) or Sotolacib) will be allowed. Dose reductions for each oral agent are discussed in detail elsewhere in this example.
[0558] Compound (10b)
[0559] Dose modification decisions for compound (10b) should be based on the CTCAE grading scale v5.0 and according to Table 8. If a drug-related AE is not specified in the table, the dose may be reduced or maintained or permanently interrupted at the discretion of the investigator for the safety of the patient.
[0560] For each patient, a maximum of two dose reductions of Compound (10b) will be allowed. Dose reduction of Compound (10b) means treatment at the next lower previously tested dose level, as summarized in Table 7. If a dose reduction below the lowest previously tested Compound (10b) dose is required, the dose should be selected after discussion between the Investigator and the Medical Monitor.
[0561] Table 8: Dose adjustment of compound (10b) for drug-related adverse events
[0562]
[0563] a These general guidelines constitute guidance to researchers and may be supplemented by discussions with the medical monitor in specific circumstances.
[0564] Other permitted compounds (10b) Dose adjustments
[0565] Treatment interruptions and dose adjustments of compound (10b) other than those mentioned above may be considered following discussion between the Investigator and the Medical Monitor and appropriate documentation of the justification.
[0566] Any changes should be within the following guidelines:
[0567] Further dose reductions of compound (10b) may be performed to maintain clinically significant drug-related AEs ≤ Grade 1. Dose adjustments of more than 1 dose level at a time may be considered when toxicity has resolved, as judged in the best interest of the patient (e.g., severe myelosuppression, lactic acidosis).
[0568] If a Grade 3 AE believed to be related to Compound (10b) is observed, treatment may be delayed for up to 2 weeks to allow for resolution of toxicity, with retreatment at a reduced dose at the discretion of the investigator. If Grade 3 nausea, vomiting, diarrhea, or clinically significant electrolyte abnormalities occur and resolve within 3 days of optimal therapy, treatment may be resumed without dose reduction. If recurrent Grade 3 nausea, vomiting, diarrhea, or clinically significant electrolyte abnormalities occur for >3 days, treatment may be resumed at a reduced dose after resolution of symptoms.
[0569] • If a patient experiences more than one AE, the Compound (10b) dose decision will be based on the most severe AE.
[0570] Patients who require a dose reduction and subsequently experience a recurrent clinically significant drug-related AE may undergo one additional dose reduction. Patients who continue to experience this event after two dose reductions will be withdrawn from the study. The lower dose will be based first on the SRC-cleared lower dose as part of the dose escalation for this study, and if a lower dose is required, based on the SRC-cleared dose in Study NAV-1001.
[0571] Sotolacib
[0572] According to the LUMAKRAS product package insert (LUMAKRAS package insert 2021, the entire contents of which are incorporated herein by reference), two dose reductions of sotolacib are allowed in the case of adverse reactions (reduced to 480 mg / day; reduced to 240 mg / day). If the patient cannot tolerate the minimum dose of 240 mg / day, the drug should be discontinued.
[0573] Dose modifications for sotolacizumab due to adverse reactions are shown in Table 9.

[0580] Effectiveness Assessment
[0581] A restaging scan (computed tomography [CT], MRI, or positron emission tomography / CT [PET-CT]) will be performed. Confirmatory scans should be obtained at least 4 weeks after the initial documentation of an objective response (i.e., PR or CR according to RECIST v1.1). The type of scan obtained is at the discretion of the investigator as appropriate for the disease. However, the same approach should be used for the duration of the study.
[0582] Patients who discontinue treatment for reasons other than radiological PD will continue to have radiological assessments based on standard of care imaging, with data reported as they become available, or upon initiation of subsequent anticancer therapy, death, or patient withdrawal of consent for radiological assessment, whichever occurs first.
[0583] Tumor response will be assessed using RECIST v1.1 (Eisenhauer Eur J Cancer; 2009; 45(2): 228-247). Tumor response will be assessed locally by the investigator for the study; scans for the Phase 1b portion of the study will also be read by a blinded independent central review (BICR). Progression-free survival will be determined based on the date of the first documented progression or death attributed to any cause.
[0584] Pharmacokinetics (PK) and pharmacodynamics (PD)
[0585] Pharmacokinetics
[0586] Blood samples will be collected from all enrolled patients participating in the study for PK evaluation of compound (10b) and Sotolacib. The time points for blood sample collection for PK of compound (10b.) and Sotolacib are summarized in Table 10. Additional details on sample collection and storage can be found in the laboratory manual.
[0587] Table 10: Compound (10b) and Sotolacib PK sample collection schedule
[0588]
[0589] A. Collection was pre-dose (ie, approximately 24 hr [± 2 hr] after administration of study treatment on the previous day, but prior to study treatment administration on the day of the visit).
[0590] On the day of PK sampling, patients should take study medication as directed by study staff in the clinic. Patients who forget and take their medication at home will be excluded from the PK analysis on that day; blood samples should not be collected from them. Complete dosing information, including the date and time of the actual blood draw and the time of the last study treatment dose before sampling, should be obtained on all sampling days and recorded on the appropriate blood collection CRF. If any of the scheduled sampling times are missed or samples are not drawn according to the schedule, the actual collection date and time will be recorded and the remaining samples will be collected as scheduled as possible.
[0591] Steady-state (C2D1 and beyond) PK samples should be collected after at least 7 consecutive days of each study treatment administration. If a study visit cannot be rescheduled within an acceptable window, PK samples should not be drawn.
[0592] If vomiting occurs within 4 hours of compound (10b) or sotolacib administration on the day of PK blood sampling, the time of vomiting should be recorded (using a 24-hour clock). No other compound (10b) or sotolacib should be administered to replace the vomited substance. The occurrence and frequency of any vomiting during the treatment cycle must be recorded in the AE CRF. PK collections should continue as planned in all cohorts.
[0593] Pharmacodynamics
[0594] Blood and tumor samples will be used to evaluate the pharmacodynamic effects of the combination of compound (10b) and sotolacib and potential mechanisms of anti-tumor response and resistance, including but not limited to the evaluations provided in Table 11. These samples will also be used to develop biomarkers that can be used to predict response or resistance to the combination of compound (10b) and sotolacib.
[0595] If at all feasible, a fresh tumor biopsy should be collected from all patients enrolled in the study. If a fresh tumor biopsy was not completed during molecular prescreening and is not feasible during screening, an archived tumor biopsy that was preferably collected within 6 months but no longer than 2 years of enrollment and has sufficient tumor for central testing of KRAS G12C mutations may be used. Fine needle aspirates or other cytology samples are not acceptable.
[0596] Patients may be enrolled even when a tumor biopsy is not available in the judgment of the Medical Monitor in consultation with the Investigator. Enrollment of patients without tumor biopsy collection will be handled on a case-by-case basis by the Medical Monitor.
[0597] The samples obtained will be used in various biomarker studies, including:
[0598] Gene expression within biopsied tumor tissue and circulating in the blood to identify genes or gene markers whose expression is modulated by compound (10b) and which can serve as pharmacodynamic biomarkers.
[0599] Molecular analysis (e.g., NGS, PCR, etc.) of tumor biopsies and ctDNA (liquid biopsies) to evaluate potential mechanisms of drug resistance.
[0600] pSHP2 and pERK were assessed by immunohistochemistry in tumor tissues as indicators of MAPK pathway flux.
[0601] Tumor microenvironment (TME) analysis in tumor biopsies by IHC or multiplex immunofluorescence as an indicator of tumor immune cell infiltration and activation.
[0602] Table 11: Pharmacodynamic evaluation
[0603]
[0604] A. Samples should be collected after administration of compound (10b) for at least 7 consecutive days.
[0605] BOIN Design
[0606] A BOIN design with a target toxicity rate of φ = 0.25 will be used to find the MTD of the combination of compound (10b) and sotolacib. Figure 6 As shown in , the BOIN design uses the following rules, optimized to minimize the probability of incorrect dose assignment, to guide dose escalation / de-escalation:
[0607] If the observed DLT rate at the current dose is ≤ 0.197, the dose will be escalated to the next higher dose level;
[0608] If it is ≥ 0.298, the dose is decreased to the next lower dose level;
[0609] .Otherwise, remain at current dose.
[0610] For the purpose of overdose control, if Pr(p j >0.25|data)>0.95, then dose j and higher levels will be eliminated from further examination, where p j is the true DLT rate at dose level j, j = 1, …, 3. This posterior probability is based on the β-binomial model y j |p j ~ Binomial (p j ) evaluation, where p j ~ uniform (0, 1), where y j is the number of DLTs experienced by patients at dose level j. The trial was terminated for safety when the lowest dose was eliminated. The probability cutoff of 0.95 was chosen to conform to the convention that when the target DLT rate Φ ≤ 1 / 6, the dose at which 3 / 5 patients experienced DLT was eliminated.
[0611] The steps to implement the BOIN design are described below:
[0612] 1. To assign doses to the next cohort of patients (phase to be completed by the SRC), dose escalation / decrease will be performed according to the rules shown in Table 12 and based on a target toxicity rate of 25%. When using Table 12, please note the following:
[0613] a. "Eliminate" means eliminating current and higher doses from the trial to prevent treatment of any future patients at these doses because of excessive toxicity.
[0614] b. When a dose is eliminated, the dose is automatically reduced to the next lower level. When the lowest dose is eliminated, the trial will be terminated for safety. In this case, no dose should be selected as the MTD.
[0615] c. If none of these actions (ie, ramp up, ramp down, or elimination) are triggered, new patients will be treated at the current dose.
[0616] d. If the current dose is the lowest dose and the rule indicates dose reduction, new patients will be treated at the lowest dose unless the number of DLTs reaches the elimination boundary, at which point the trial will be terminated for safety.
[0617] e. If the current dose is the highest dose and the rule indicates dose escalation, the new patient will be treated at the highest dose.
[0618] f. In the event that operational / practical circumstances result in overenrollment (i.e., >7 DLT-evaluable patients per current cohort size), the next dose level decision will be based on the actual number of DLT-evaluable patients in the cohort.
[0619] 2. Dose escalation will start with 5-7 DLT evaluable patients enrolled in compound (10b) 250 mg plus sototraxib 960 mg (i.e., the lowest dose level). According to Table 12, for illustrative purposes, if a DLT is observed in any of the 6 evaluable patients enrolled, then escalate to the next dose level. If DLT is observed in ≥2 / 6 evaluable patients enrolled, then decrement to a lower dose.
[0620] 3. If escalating to a higher dose level, follow the same approach as in 2.
[0621] 4. The maximum sample size for dose escalation is 21 DLT-evaluable patients and 10 DLT-evaluable patients in any dose level cohort.
[0622] Table 12: Dose escalation decision rules
[0623]
[0624] Abbreviation: DLT = dose-limiting toxicity
[0625] a When none of these actions (ie, escalation, decrementation, or elimination) are triggered, stay at the current dose for treatment of the next cohort of patients. Note that the "number of DLTs" is the number of patients with at least 1 DLT.
[0626] After the trial is completed, the MTD will be selected based on ordinal regression as specified in Liu and Yuan (2015). This calculation is implemented by the "estimate MTD" of the BOIN design desktop program. In particular, the dose whose isotonic estimate of the DLT rate is closest to the target DLT rate is selected as the MTD. If there is a connection, a higher dose level is selected when the isotonic estimate is lower than the target DLT rate, and a lower dose level is selected when the isotonic estimate is higher than or equal to the target DLT rate. The RP1bD for cohort expansion will be selected based on toxicity (i.e., MTD) and other clinical considerations (e.g., PK / pharmacodynamics).
[0627] Table 13 shows the operational characterization of the trial design based on 1000 simulated trials using the BOIN design desktop program (MD Anderson Cancer Center, 2021). The operational characterization shows that the design selects the true MTD with a high probability (if any) and allocates more patients to the dose level with the DLT rate closest to the target 0.3.

[0634] Effectiveness
[0635] Patient Evaluation & Statistics
[0636] Patients with solid tumors will undergo disease assessments at Screening and then every 8 weeks thereafter unless more frequent assessments are warranted clinically or per RECIST v1.1 criteria outlined herein.
[0637] Descriptive statistics will be provided for continuous variables, and frequency tables will be used to summarize categorical variables. Best overall response and proportion of patients experiencing CR, PR, SD, and PD among patients with measurable disease will be shown, along with the corresponding 95% exact CIs.
[0638] Time-to-event variables (eg, DOR, PFS, and OS) will be analyzed by the Kaplan-Meier method. The median, as well as the 25%, 75%, minimum, and maximum, time-to-event values will be estimated, and Kaplan-Meier curves will be plotted.
[0639] Anti-tumor effect - solid tumors
[0640] Tumor response is the primary efficacy endpoint in Phase 1b dose expansion / optimization; Patients will be evaluated with standard criteria (note: all patients must have measurable disease when enrolled in the study, and will therefore be evaluated according to RECIST v1.1 criteria). For the purpose of this study, tumor response should be evaluated every 8 weeks (± 7 days) (i.e., the 1st day of each odd-numbered cycle), thereafter until PD, while the patient is undergoing treatment. Disease assessments for patients interrupted for reasons other than PD are summarized in Section 7.6 of the clinical protocol. In addition to baseline scans, confirmation scans will also be obtained at least 4 weeks after the first recording of objective response (i.e., PR or CR).
[0641] In this study, response and progression will be evaluated using the new international standard RECIST v1.1 proposed by the RECIST committee (Eisenhauer et al., Eur J Cancer; 2009; 45(2): 228-247). Only the change in the largest diameter (a one-dimensional measurement) of the tumor lesion is used in the RECIST criteria.
[0642] Disease parameters
[0643] Measurable disease. Measurable lesions were defined as those that could be accurately measured >10 mm in at least one dimension (the longest diameter [LD] to be recorded) by scanning (CT, MRI, or PET-CT; scan slice thickness should not exceed 5 mm). Millimeters (or decimal fractions of centimeters).
[0644] Lesions cannot be measured. All other lesions (or disease sites), including small lesions (LD <10 mm or pathological lymph nodes ≥10 mm to <15 mm), were considered non-measurable disease. Bone lesions, leptomeningeal disease, ascites, pleural / pericardial effusions, cutaneous / pulmonary lymphangitis, mastitis, abdominal masses (without subsequent CT, MRI, or PET-CT), and cystic lesions were all considered true non-measurable disease.
[0645] Target lesion. All measurable lesions representing all involved organs should be identified as target lesions at baseline, with a maximum of 2 lesions per organ and a total of 5 lesions, and recorded and measured. Target lesions should be selected based on their size (lesions with LD) and suitability for accurate repeated measurements (by imaging counts or clinically). The sum of the LD of all target lesions will be calculated and reported as the baseline sum LD. The baseline sum LD will be used as a reference to characterize the objective tumor response.
[0646] Non-target lesions. All other lesions (disease sites) (including any measurable lesions in excess of and above the 5 target lesions) should be identified as non-target lesions at baseline and should also be recorded. These lesions do not need to be measured, but the presence or absence of each lesion should be noted throughout follow-up.
[0647] Methods used to assess measurable disease
[0648] All measurements should be made using a ruler or calipers and recorded in metric notation. All baseline evaluations should be performed as close to the start of treatment as possible and never more than 4 weeks before the start of treatment.
[0649] Each identified and reported lesion should be characterized using the same assessment method and the same technology at baseline and during follow-up. When both methods have been used to assess the antitumor effect of treatment, imaging-based evaluation is superior to evaluation by clinical examination.
[0650] CT, MRI, or PET-CT scanning should be used to measure selected lesions for response assessment : These techniques should be performed with serial sections ≤5 mm thick. Each identified and reported lesion should be characterized using the same assessment method and the same technique at baseline and during follow-up.
[0651] Tumor markers. Tumor markers alone cannot be used to assess response. If a marker is initially above the upper limit of normal, it must be normalized so that the patient is considered to have a complete clinical response. Specific additional criteria for standardized use of prostate-specific antigen and CA-125 responses to support clinical trials are being developed.
[0652] Cytology, Histology: These counts can be used to differentiate between PR and CR in rare cases (eg, residual lesions in tumor types such as germ cell tumors where residual benign tumor is known to remain).
[0653] When measurable tumor meets the criteria for response or stable disease, cytologic confirmation of the neoplastic origin of any effusion that appears or worsens during treatment is mandatory to distinguish between response or stable disease (effusions can be a side effect of treatment) and PD.
[0654] Reaction criteria
[0655] Evaluation of target lesions
[0656] Complete Response (CR): All target lesions disappeared.
[0657] Partial Response (PR): At least 30% reduction in the sum of LD of all target lesions, using the baseline sum LD as reference.
[0658] Progressive disease (PD): The sum of the target lesion LDs increased by at least 20%, taking as reference the minimum sum LD recorded since the start of treatment or the appearance of one or more new lesions.
[0659] Stable disease (SD): If the disease was neither sufficiently reduced to meet the criteria of PR nor sufficiently increased to meet the criteria of PD, the smallest summed LD from the start of treatment was used as the reference.
[0660] Evaluation of non-target lesions
[0661] Complete Response (CR): All non-target lesions disappeared and tumor marker levels normalized.
[0662] NOTE: If tumor markers are initially above the upper limit of normal, they must be normalized in order for the patient to be considered in complete clinical response.
[0663] Stable disease (SD): Persistence of one or more non-target lesions and / or maintenance of tumor marker levels above normal limits.
[0664] Progressive disease (PD): Appearance of one or more new lesions and / or unequivocal progression of existing non-target lesions.
[0665] Although unequivocal progression of only “non-target” lesions is an exception, in such cases the opinion of the attending physician should prevail and progression status should be confirmed later by the review team (or the principal investigator).
[0666] Best overall response evaluation
[0667] Best overall response is the best response recorded from the start of treatment until disease progression / relapse (for PD, the smallest measurement recorded from the start of treatment is used as reference). The patient's best response assignment will depend on the achievement of measurement and confirmation criteria.
[0668] Table 14: Evaluation of Best Overall Response
[0669]
[0670] Reaction duration
[0671] Duration of overall response: DOR was measured from the time when CR or PR (whichever was recorded first) was met until the first date of objectively documented relapse or PD (for PD, the smallest measurement recorded from the start of treatment was used as reference).
[0672] Duration of overall CR was measured from the time when CR criteria were first met until the first date of objectively documented recurrent disease.
[0673] Duration of disease stability: Stable disease was measured from the start of treatment until progression criteria were met, using the smallest measurement recorded from the start of treatment as the reference.
[0674] Progression-free survival
[0675] Progression-free survival (PFS) will be defined as the treatment start date to the event date, defined as the first documented progression or death from any cause. If the patient does not experience an event, PFS will be censored according to the details described in the SAP. Kaplan-Meier analysis of PFS will be provided.
[0676] Although the foregoing disclosure has been described in some detail by way of illustration and example for the sake of clarity of understanding, it will be appreciated by those skilled in the art that certain changes and modifications may be implemented within the scope of the appended claims. In addition, each reference provided herein is incorporated by reference in its entirety to the same extent as each reference is incorporated by reference individually. If there is a conflict between the present application and the references provided herein, the present application shall prevail.
