Attorney Docket No.: HOT-023WOCOMBINATION CBL-BI AND ANTIHISTAMINE FOR CANCER THERAPYCROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit and priority of U.S. Provisional Application No. 63 / 691 ,825 filed September 6, 2024, and U.S. Provisional Application No. 63 / 718, 1 15 filed November 8, 2024, which is hereby incorporated by reference in its entirety for all purposes.FIELD

[0002] The present field involves methods of administering a Casitas B -lineage lymphoma proto-oncogene B inhibitor (CBL-Bi) for treating a cancer in a subject and methods of administering a CBL-Bi in combination with a pre-treatment to counteract the side effects of the CBL-Bi in the subject.BACKGROUND

[0003] Novel cancer immunotherapeutics have been developed in the past decade, showing promise as new candidates for treating cancer. Several therapies, such as immune checkpoint inhibitors, are being investigated across a range of different cancer types. Not all patients respond to or have durable responses to currently available agents. In addition, many cancer treatment options, such as chemotherapies and radiotherapies, lead to severe side effects that make the treatments difficult to withstand for patients. The side effects of these therapeutics further limit the options available for the cancer patients. Thus, there is a need to identify new drug candidates for treating patients with cancers which do not respond to or are not as effective against currently available drugs. Furthermore, there is an unmet need for methods of treating cancer in patients with reduced side effects from the therapies.SUMMARY

[0205] Female C57BL / 6 mice, aged 6-8 weeks, were inoculated subcutaneously into the right flank with Pan02 (pancreatic cancer) cells. Female BALB / c mice of the same age range received subcutaneous injections of H22 (hepatoma), CT-26 (colon carcinoma), and EMT-6 (mammary carcinoma) cells in the flank. Tumor growth was monitored by caliper measurements, and tumor volume was determined using the formula (length x width2) / 2. Upon tumors reaching an average volume of 80-100 mm3, mice were randomly allocated to351PTS / 200114525.1Attorney Docket No.: HOT-023WO treatment and control groups (n=10 per group). Treatment groups received Compound 1 at 60 mpk orally twice daily. Control groups were administered the vehicle solution following the same schedule. Tumor volumes and body weights were recorded biweekly throughout the study. Mice were euthanized if tumor volumes reached 2000 mm3or if signs of distress were noted. At the endpoint, 3-5 tumors from each group were excised and processed to analyze gene expression using NanoString™ mouse PanCancer immune profiling panel. NanoString analysis calculated cell type scores using the arithmetic mean of the log2-transformed normalized expression of all selected marker genes for the cell type, which correlates with the abundance of that cell population.

[0206] FIGs. 1A-1D show the change in cell scores of different cell populations in murine tumor models EMT6 (FIG. 1A; colon cancer model), Pan02 (FIG. IB; pancreatic cancer model), H22 (FIG. 1C; hepatoma model), and CT26 (FIG. ID; colon cancer model) treated with vehicle or Compound 1 at 60 mpk. Increased mast cell numbers were observed in all four cancer tumor models when treated with Compound 1 compared to the vehicle group, indicating that Compound 1 treatment enhances innate immune response.

[0207] FIG. 2 shows the cell score of mast cells in different murine tumor models (EMT6, Pan02, H22, and CT26) treated with vehicle or Compound 1 at 60 mpk twice a day (BID). Increased mast cell numbers were observed in all four cancer tumor models, and the magnitude of the effect is different in the different tumor models. These results indicate that Compound 1 treatment increases mast cell number in tumors.

[0208] FIG. 3A shows the cell score of mast cells present in the tumors of CT26 mouse models administered with vehicle, different doses and frequencies of Compound 1 alone, an anti-PD-1 inhibitor alone, or different frequencies of Compound 1 in combination with the anti-PD-1 inhibitor. FIGs. 3B and 3C show normalized mRNA levels of mast cell markers Cmal (FIG. 3B) and Tpsabl (FIG. 3C) for the same treatment groups evaluated in the data shown in FIG. 3A. Cmal and Tpsabl are genes specifically expressed by mast cells.Increased cell score and increased expression of Cmal and Tpsabl were observed in all tumors from groups treated with Compound 1. Tumors from animals treated only with the anti-PD-1 inhibitor were found to have similar mast cell scores, and Cmal and Tpsabl expression levels as the vehicle groups. These results suggest that Compound 1 but not the anti-PD-1 inhibitor increase the presence of mast cells in the tumor.

[0209] FIG. 4A shows the cell score of mast cells present in the tumors of CT26 mouse models administered with vehicle, Compound 1 alone, an IL- 15 agonist alone, or Compound361PTS / 200114525.1Attorney Docket No.: HOT-023WO1 in combination with the IL- 15 agonist. FIGs. 4B and 4C show normalized mRNA levels of mast cell markers Cmal (FIG. 4B) and Tpsabl (FIG. 4C) for the same treatment groups evaluated in the data shown in FIG. 4A. Increased cell score and increased expression of Cmal and Tpsabl were observed in all tumors from groups treated with Compound 1. Tumors from animals treated only with the IL- 15 agonist were found to have similar mast cell scores, and Cmal and Tpsabl expression levels as the vehicle groups. These results suggest that Compound 1 but not the IL- 15 agonist increase the presence of mast cells in the tumor.

[0210] These results indicate that administration of Compound 1 increases the number of mast cells in tumors, and that this feature is not observed with other cancer immunotherapeutic drugs, such as anti-PD-1 and IL- 15 agonists.Example 2: CBL-B inhibitor increases the presence of mast cells in tumors in a dosedependent manner

[0211] Female BALB / c mice, aged 6-8 weeks, were inoculated subcutaneously into the right flank with CT-26 (colon carcinoma) cells. Tumor growth was monitored by caliper measurements, and tumor volume was determined using the formula (length x width2) / 2. Upon tumors reaching an average volume of 80-100 mm3, mice were randomly allocated to treatment and control groups (n=10 per group). Treatment groups received Compound 2 at 3 mpk, 10 mpk, or 30 mpk orally twice a day (BID), or with Compound 2 at 6 mpk, 20 mpk, or 60 mpk once a day (QD). Control groups were administered the vehicle solution following the same schedule. Tumor volumes and body weights were recorded biweekly throughout the study. Mice were euthanized if tumor volumes reached 2000 mm3or if signs of distress were noted. At the day 18, three tumors from each group were excised and processed to analyze gene expression using NanoString™ mouse PanCancer immune profiling panel. NanoString analysis calculated cell type scores using the arithmetic mean of the log2-transformed normalized expression of all selected marker genes for the cell type, which correlates with the abundance of that cell population.

[0212] FIGs. 5A and SB show normalized mRNA levels of mast cell markers Cmal (FIG. 5A) and Tpsabl (FIG. 5B) in the tumors of CT26 mouse models administered with vehicle, with Compound 2 at 3 mpk, 10 mpk, or 30 mpk twice a day (BID), or with Compound 2at 6 mpk, 20 mpk, or 60 mpk once a day (QD). Increased mast cell recruitment to the tumors (as measured by the expression of both Cmal and Tpsabl) was observed in a dose-dependent371PTS / 200114525.1Attorney Docket No.: HOT-023WO manner in groups administered with Compound 2at 10 mpk, or 30 mpk twice a day (BID), or with Compound 2at 6 mpk, 20 mpk, or 60 mpk once a day (QD). These results indicate that increased doses of Compound 2 increase the amount of mast cells recruited to the tumors.Example 3: CBL-Bi successfully inhibits tumor growth across different dosing schedules

[0213] BALB / C mice were inoculated in the right front flank with CT26 cancer cells. Compound 2 was administered when the tumor reached about 80mm3in volume.

[0214] FIGs. 6A-6C show tumor volume (in mm3) over 13 days in CT26 mouse models administered with Compound 2at 6 mpk (FIG. 6A), 12 mpk (FIG. 6B), or 20 mpk (FIG. 6C) once day (QD), once a week (QW), or twice per week (BIW), or with vehicle. FIG. 7 shows tumor volume (in mm3) after 13 days from treatment in CT26 mouse models administered with Compound 2at 6 mpk, 12 mpk, or 20 mpk once a day (QD), once a week (QW), or twice per week (BIW), or with vehicle. Table 2 shows the mean percent difference of tumor volume between the vehicle group and the different treatment groups.Table 2. Mean percentage of tumor growth inhibition in CT26 tumor mouse models after 13 days of Compound 2 administration

[0215] Tumors from CT26 mouse model treated with Compound 2 at doses of either 6 mpk, 12 mpk, or 20 mpk once a day showed delayed increase in volume compared to the vehicle group. Administration of Compound 2 at doses of either 6 mpk, 12 mpk, or 20 mpk twice per week consistently demonstrated tumor growth inhibition compared to the vehicle group. Comparable tumor growth was observed between the vehicle group and the group administered with weekly doses of Compound 2 at 6 mpk. Interestingly, administration of Compound 2 at any dose once a day showed preferred efficacy in tumor growth inhibition.381PTS / 200114525.1Attorney Docket No.: HOT-023WOThese results indicate that different dosing schedules are efficacious in tumor growth inhibition, with a preference for a daily dosing schedule. A dosing window of less than 2 weeks poses a challenge in observing the effects of intermittent dosing.Example 4: CBL-Bi slows tumor growth when administered as a prophylactic treatment across different dosing schedules

[0216] BALB / C mice were inoculated with EG7 cancer cells. Compound 2 was administered as a pre-treatment 3 days before inoculation with cancer cells.

[0217] FIG. 8 shows tumor volume (in mm3) over 18 days in EG7 mouse models administered with Compound 2 at 20 mpk once a day (QD), 20 mpk twice per week (BIW), or 60 mpk twice per week (BIW) or with vehicle. FIG. 9 shows tumor volume (in mm3) after 18 days from treatment in EG7 mouse models administered with Compound 2 at 20 mpk once a day (QD), 20 mpk twice per week (BIW), or 60 mpk twice per week (BIW) or with vehicle. Tumor growth inhibition was observed through the 18 days, when animals were administered Compound 2 at 20 mpk once day (QD) or twice per week (BIW) or 60 mpk twice per week (BIW) as a prophylactic. Consistent with these observations, the tumor volume of animals treated with Compound 2 was significantly lower compared to the vehicle group. These results indicate that administering Compound 2 prophylactically once per day or twice per week are equally efficacious in inhibiting tumor growth.Example 5: Exemplary Dosing Regimens involving CBL-Bi and pre-treatment medications

[0218] FIGs. 10A and 10B show exemplary dosing regimens for Compound 2 administered twice per week (FIG. 10A) or once per week (FIG. 10B), including exemplary dosing for the pre-treatment medications (anti-nausea medication and steroids) and daily administration of anti-histamines and H2 receptor antagonists.

[0219] Phase 1 is a multipart study in which patients will receive Compound 2 as either monotherapy or in combination with the anti-PD-1 antibody cemiplimab. FIG. 11 is a diagram describing the phase I clinical trial evaluating Compound 2 alone (Part A) and in combination with cemiplimab (Part B) in patients with advanced solid tumors.

[0220] The monotherapy will consist of two parts: (a) dose escalation and (b) dose optimization. In the monotherapy dose escalation, cohorts of patients receive increasing doses of Compound 2. In the monotherapy dose optimization, several cohorts of patients with pre- 391PTS / 200114525.1Attorney Docket No.: HOT-023WO specified tumor types will be evaluated utilizing a dose and schedule of Compound 2 deemed safe in part (a).

[0221] The combination therapy will consist of a dose escalation of Compound 2 given in combination with the standard dose / regimen of cemiplimab. Dosing may commence prior to the completion of the monotherapy part (a) of the study, but the starting dose of Compound 2 in the combination therapy will be at least 2 dose levels lower than the cleared Compound 2 dose in the monotherapy part (a) of the study. The combination therapy dose escalation study will be followed by a combination dose optimization study in which several cohorts of patients with pre-specified tumor types will be evaluated utilizing a dose and schedule of Compound 2 deemed safe in the combination dose escalation study.Example 6: Treatment using Compound 2 demonstrates safety, tolerability, and acceptable pharmacokinetics

[0222] Table 3 shows the demographics of the patients of a phase I clinical trial. Patients were generally older, with a diversity between sexes. Most patients had an ECOG status of 1, a median of almost 4 years since diagnosis and were heavily pretreated with a median of 4 prior lines of therapy, with most having had at least 1 prior experience on anti-PD- 1 and anti- PD-L1 containing regimen. There was also a diversity of tumor types indicative of the significant heterogeneity that are often observed in early clinical trials.Table 3. Overview of Compound 2 monotherapy patient demographics401PTS / 200114525.1Attorney Docket No.: HOT-023WO

[0223] Table 4 shows the safety and tolerability results of Compound 2 monotherapy from phase I clinical trial. Single agent use of Compound 2 demonstrated an acceptable safety profile across the dose range tested. There have been no dose-limiting toxicities and most treatment related adverse events have been Grade 1 or 2. The predominant adverse events have been related to gastrointestinal effects, particularly nausea, vomiting and diarrhea, which occurred on days of dosing and have generally been mitigated or minimized with a prophylactic pre-treatment regimen. These effects show no similarities to colitis associated with other immune-oncology agents but they are believed to be related to local effects on the immune system. Even in the small number of cases of Grade 3 toxicity, there was no discontinuation of Compound 2 treatment. These data demonstrated that Compound 2 could be safely administered to patients despite a wide range of co-morbidities and concomitant treatments.Table 4. Safety and tolerability results of Compound 2 monotherapy from phase I clinical trial411PTS / 200114525.1Attorney Docket No.: HOT-023WO

[0224] FIGs 12A and 12B are graphs showing pharmacokinetics of Compound 2 in subjects administered with 5 mg, 10 mg, 20 mg, 30 mg, and 40 mg by measuring Compound 2 plasma concentration (in ng / mL) over 24 hours after administration on day 1 (FIG. 12A) and day 22 (FIG. 12B) from beginning of treatment. Pharmacokinetic analyses demonstrated a concentration vs. time profile that is typical of an oral drug. Plasma half life was about 3-5 hours with acceptable patient to patient variability. Plasma concentrations of Compound 2, particularly at 20 mg and higher, were clearly above key benchmarks of immune activation that were associated with robust anti-tumor activity in preclinical models. These PK data suggest that systemic exposures were well within a pharmacologically active range, which is further supported by initial target engagement observationsExample 7: Compound 2 increases Notch 1 levels in peripheral T-cells

[0225] Flow cytometry was performed on peripheral T-cells from subjects treated with Compound 2 to measure levels of surface Notch 1 in the cells as an indicator of CBL-B inhibition.

[0226] FIG. 13 is a graph showing percent change in the expression of Notchl relative to CD8 in peripheral T-cells after 4 hours and 24 hours from administration of Compound 2 at 5 mg, 10 mg, 20 mg, 30 mg, and 40 mg.

[0227] Two indicators of dose-related CBL-B inhibition by Compound 2 were observed. First, at the time of near maximal plasma concentrations (4 hours), a significant increase in Notchl expression was observed from 5 mg to 10 mg and then a plateau thereafter. Second, at 24 hours post-dose, when plasma concentrations of Compound 2 were low to below detection, sustained Notchl was observed at 20 mg and higher. The prolonged effect on target engagement, as observed by increased Notchl levels, aligns with the very slow off rate of Compound 2.42IPTS / 200114525.1Attorney Docket No.: HOT-023WOExample 8: Compound 2 activates the immune system

[0228] FIGs. 14A-14C are box-and-whisker graphs showing changes in overall cytokine expression (FIG. 14A) at day 1 of Compound 2 administration, and IFNy secretion at day 1 (FIG. 14B) and day 22 (FIG. 14C) of Compound 2 administration at doses of 5 mg, 10 mg, 20 mg, 30 mg, and 40 mg.

[0229] As shown in FIG. 14A, Compound 2 caused a dose-dependent increase in inflammatory cytokines and chemokines also found increased in subjects with loss-of- function mutations in their CBL-B gene (IL-6, TNF-a, IL-10, CXCL9, and CXCL10; Janssen et al. (2022). J. Clin. Invest, 132(20): el54487.). These data show that Compound 2 can phenocopy what has been reported with CBL-B loss-of-function mutations in humans.

[0230] Changes in systemic levels of IFNy were also assessed (FIGs. 14B and 14C). Both on days 1 and 22, a dose-related increase in IFNy levels were observed, with generally more substantial and sustained levels observed over time with administration of Compound 2 at 30 and 40 mg. Taken together, these data suggest that pharmacologically active exposures to Compound 2 were achieved, as observed by the downstream immune activation in the periphery.Example 9: Compound 2 treatment showed signs of clinical benefit

[0231] Table 5 shows the clinical effects observed in subjects treated with Compound 2 during phase I of clinical trial. Indications of some clinical benefit were observed in 10 out of the 28 subjects administered with Compound 2 monotherapy. The clinical effects were observed in the tumor status of anal and rectal cancer patients, and short-term reductions or mixed responses in subjects with cutaneous squamous cell and melanoma. A very significant decrease in one target lesion was observed in a subject with melanoma, but an appearance of a new lesion was also observed. There were also decreases in well known peripheral markers of disease like CAI 25 or PSA levels in subjects with ovarian and prostate cancer, respectively. These were interesting examples because the benefits to these two patients were only observed following intra-patient dose escalation to higher doses where more consistent evidence of pharmacologic activity were observed. The range of patients with some evidence of benefit included tumor types where immunotherapy is not standard of care, as well as those like non-small cell lung carcinoma (NSCLC), a type of cancer broadly considered to be immunoresponsive.431PTS / 200114525.1Attorney Docket No.: HOT-023WOTable 5. Clinical effects observed in subjects treated with Compound 2 during phase I of clinical trials* Days of stable disease were calculated from the first dosing day as a baseline until cancer progression.** Scan for clinical assessment, not tumor evaluation per protocol

[0232] FIG. 15 is a graph showing the IFNy levels at days 1 and 22 at pre-dosing and 2, 4, and 8 hours after administration of Compound 2 in a subject with non-small cell lung cancer subject. Table 6 shows the tumor response outcomes of the patient based on clinical and radiographic observations and measurements of peripheral biomarkers.Table 6. Summary of tumor response outcomes in subject with non-small cell lung cancer treated with Compound 244IPTS / 200114525.1Attorney Docket No.: HOT-023WO* “SD” refers to “stable disease” and “PD” refers to “progressive disease.”

[0233] Compound 2 administration induced significant increases in IFNy levels, which were sustained over time (FIG. 15). Clinical improvements were observed in the subject throughout the treatment duration. Furthermore, radiographic data showed stable disease up to week 36, as determined by the size of the lesion in the subject. Lastly, a decrease in circulating tumor DNA (ctDNA) was observed during the treatment. Overall, this patient was on study with a monotherapy of Compound 2 for nearly 9 months. These data are illustrative of the phase I monotherapy dose escalation outcomes.Example 10: Compound 2 treatment modulates different immune related pathways

[0234] FIG. 16 depicts a dose dependent modulation of immune related transcriptional pathways in peripheral blood samples following administration of Compound 2. Patient peripheral blood samples were analyzed. Here RNA was extracted from patient samples (at various timepoints during the first cycle of treatment with Compound 2) and tested on a Nanostring Immunology V2 chip for expression analysis. Gene expression was categorized into different pathways. These different pathways were annotated by Nanostring and these pathways were applied to the RNA expression data from patients in the dose escalation cohorts. FIG. 16 shows 6 different pathways identified as being modulated by, and also showing a dose dependent increase to, Compound 2. The 6 different pathways included 1) chemokine signaling, 2) cytokine signaling, 3) host pathogen interaction, 4) innate immune system, 5) lymphocyte tracking, and 6) type II interferon signaling.Example 11: Compound 2 treatment impacts TCR and BCR repertoire metrics from peripheral samples

[0235] TCR and BCR repertoire metrics were developed at iRepertoire (Huntsville, AL) using their 7-chain assay (Hou, X. et al., Complete all-in-one immune repertoire profiling of newborn babies via novel dimer-avoided multiplex PCR (dam-PCR). J Immunol 1 May 2019;451PTS / 200114525.1Attorney Docket No.: HOT-023WO202 (1 -Supplement): 131.28, which is incorporated by reference in its entirety). Samples used for this testing were derived from peripheral blood RNA obtained across 2 time points. This included Cycle 1 Day 1 pre-dose and Cycle 2 Day 1 pre-dose from the same patients. Data shows different TCR and BCR metrics being modulated by 1 cycle of therapy with Compound 2.

[0236] FIGs. 17A-17D depict induced changes in different TCR and BCR repertoire metrics following administration of Compound 2. Specifically, FIG. 17A shows that a decrease in TCR diversity index (beta and alpha) D50 was observed in patients who benefitted from therapy suggesting a focused T-cell response. FIG. 17B shows that patients with clinical benefit showed an increase in naive B-cells undergoing mutations, and the class switch ratio (CSR) indicating an adaptive immune response. FIG. 17C shows Uniform Manifold Approximation and Projection (UMAP) analysis, which separated patients according to clinical benefit / no benefit. FIG. 17D shows key TCR and BRR indexes used in UMAP analysis.Example 12: Impact of Compound 2 treatment measured by tumor microenvironment RNA signature

[0237] FIG. 18 depicts a tumor microenvironment (TME) RNA signature testing to predict clinical benefit. Several patients with clinical benefit were found with tumor signature call near IS (top right corner) or IA (bottom right comer) suggesting those with high immune signature scores tend to benefit from Compound 2 treatment. Alternatively, the other dots shown in FIG. 18 correspond to limited benefit or no benefit.

[0238] A tumor microenvironment (TME) RNA signature was derived according to the previously published articles (Uhlik M, et al., Xerna™ TME Panel is a machine learningbased transcriptomic biomarker designed to predict therapeutic response in multiple cancers. (2023) Front. Oncol. 13:1158345, which is incorporated by reference in its entirety). The signature is made up of 124 genes across two main biological axes including angiogenesis and immune.

[0239] Samples were obtained from patients following administration of Compound 2. The RNA sequencing data was generated and then further analyzed. The data in FIG. 18 shows those patients who benefitted clinically from Compound 2 (“Clinical benefit”) had tumors that fell in the high immune signature quadrants (IS and IA) for the signature calling.461PTS / 200114525.1Attorney Docket No.: HOT-023WOOTHER EMBODIMENTS
