Current report

In June 2024, we presented additional data from SUMMIT Part 1 at the 2024 European Hematology Association (“EHA”) Congress. As of the cutoff date, December 18, 2023, patients in Part 1 treated at the recommended dose of 100 mg bezuclastinib demonstrated >90% reductions across all markers of mast cell burden. Additional data also show meaningful reduction in symptom severity and objective measures of disease, including a substantial reduction in mast cell reactions (>50%) and patients’ most severe symptoms as measured by MS2D2, clinically meaningful reduction in all individual MS2D2 TSS symptoms and across domains, as well as additional symptoms including dizziness, diarrhea severity, and brain fog, and clinically meaningful improvement in skin symptoms as well as objective reduction in skin lesions. Consistent with results previously reported, as of the December 18, 2023 cutoff date, the RP2D demonstrates a favorable safety and tolerability profile. There were no bleeding or cognitive impairment adverse events reported and no SAEs reported.

Current report

In June 2024, we presented updated positive clinical data from the lead-in portion of PEAK Part 1 at the 2024 American Society of Clinical Oncology (“ASCO”) meeting. As of the cutoff date, April 1, 2024, the 42 patients in Part 1 have been on study for a median of 15.3 months. The median progression-free survival (“mPFS”) during treatment with bezuclastinib and sunitinib was 10.2 months in all of these heavily pre-treated GIST patients. In a subset of second-line GIST patients with only prior imatinib, which most closely resembles patients currently enrolling in the Phase 3 registration-enabling PEAK study, the data demonstrate a mPFS of 19.4 months. In addition, the objective response rate (“ORR”) in all patients treated with bezuclastinib and sunitinib was 27.5% and in the subset of second-line patients the ORR was 33.3%, per investigator assessment. Combination treatment resulted in a disease control rate of 80% in all patients and 100% in second-line patients with prior imatinib only. As of the data cutoff, the combination of bezuclastinib and sunitinib does not appear to add to the severity of adverse events known to be associated with sunitinib monotherapy and is well-tolerated. The majority of treatment-emergent adverse events (“TEAEs”) were low-grade and reversible and discontinuations due to TEAEs remain limited.

Current report

In May 2024, we also announced the initiation of a new advanced Phase 2 clinical trial of bezuclastinib plus sunitinib in later line GIST patients that is being sponsored by the Sarcoma Alliance for Research through Collaboration and in collaboration with The Life Raft Group and Dana-Farber Cancer Institute. The open label, single arm Phase 2 trial is designed to evaluate the mPFS as well as the safety and tolerability of bezuclastinib plus sunitinib in 40 patients with GIST who have previously progressed on sunitinib. This trial is focused on later line patients that are not eligible for PEAK and have limited treatment options.

Current report

General and administrative expenses for the six months ended June 30, 2024 were $19.8 million, compared to $15.4 million for the six months ended June 30, 2023. The increase in general and administrative expenses was primarily due to higher personnel costs driven by an increase in headcount, including stock-based compensation expense which increased by $3.7 million for the six months ended June 30, 2024 compared to the six months ended June 30, 2023.

Current report

Interest income for the six months ended June 30, 2024 was $9.5 million, compared to $5.0 million for the six months ended June 30, 2023. The increase is due to higher average invested balances in cash equivalents and marketable securities.

Current report

On June 10, 2024, following the approval by our stockholders of an increase to the authorized shares of common stock at our 2024 annual meeting, each share of Series B Preferred Stock automatically converted into 1,000 shares of common stock, subject to certain beneficial ownership limitations. Pursuant to the terms of the Series B Certificate of Designation, on June 10, 2024, 13,712 shares of Series B Preferred Stock automatically converted to 13,712,000 shares of common stock, and 6,868 shares of Series B Preferred Stock remain outstanding as of June 30, 2024.

Previous report

Initial safety and pharmacokinetic data from the lead-in portion of the PEAK study was presented at the 2022 Connective Tissue Oncology Society (“CTOS”) annual meeting in November 2022. In June 2023, we presented additional positive lead-in data from PEAK at the 2023 annual American Society of Clinical Oncology (“ASCO”). As of the cutoff date of March 29, 2023, the combination of bezuclastinib and sunitinib was generally well-tolerated with an encouraging safety profile. Data were immature to estimate median progression free survival. The data demonstrated 55% Disease Control Rate (“DCR”) in heavily pre-treated GIST patients, including 100% DCR and 17% overall response rate in efficacy evaluable 2nd-line GIST patients. In November 2023, we presented updated clinical data from the lead-in portion of the PEAK trial at the CTOS annual meeting. Safety and tolerability data have remained consistent with the data previously presented at ASCO. Updated clinical activity from a subset of 2nd-line GIST patients demonstrates a 33% confirmed overall response rate (“ORR”) with ongoing median duration of therapy greater than 14 months. Together with clinical data previously reported, four of ten evaluable 2nd-line GIST patients treated with the combination have reached confirmed partial response status.

Previous wording

We are a biotechnology company focused on developing precision therapies for genetically defined diseases. Our approach is to design rational precision therapies that treat the underlying cause of disease and improve the lives of patients. Our most advanced program is bezuclastinib, also known as CGT9486, a highly selective tyrosine kinase inhibitor designed to potently inhibit the KIT D816V mutation as well as other mutations in KIT exon 17. In the vast majority of cases, KIT D816V is responsible for driving Systemic Mastocytosis (“SM”), a serious and rare disease caused by unchecked proliferation of mast cells. Exon 17 mutations are also found in patients with advanced gastrointestinal stromal tumors (“GIST”), a type of cancer with strong dependence on oncogenic KIT signaling. Bezuclastinib is a highly selective and potent KIT inhibitor with the potential to provide a new treatment option for these patient populations. We are developing bezuclastinib in patients living with Advanced Systemic Mastocytosis (“AdvSM”), Non-Advanced Systemic Mastocytosis (“Non-AdvSM”) and GIST. In addition to bezuclastinib, the Cogent Research Team is developing a portfolio of novel targeted therapies to help patients fighting serious, genetically driven diseases initially targeting mutations in FGFR2, ErbB2 and PI3Kα.

SUMMIT is our randomized, global, multicenter, double-blind, placebo-controlled, multi-part Phase 2 clinical trial for patients with Non-AdvSM. The study is designed to explore the safety and efficacy of bezuclastinib in patients with moderate to severe Non-AdvSM, which includes Indolent Systemic Mastocytosis (“ISM”), Smoldering Systemic Mastocytosis (“SSM”) and Bone Marrow Mastocytosis. SUMMIT Part 1 completed enrollment in the third quarter of 2023, including over enrollment at 54 patients across Part 1a and Part 1b. SUMMIT Part 2 is a registration-directed study that is currently enrolling and expected to include 159 patients. We are on-track to complete enrollment in the second quarter of 2025, with top-line results expected by the end of 2025.

From the data collected in Part 1 of SUMMIT and in accordance with FDA guidelines, we are developing a novel patient reported outcomes measure (“PROM”) called Mastocytosis Symptom Severity Daily Diary (“MS2D2”). Based on literature review, patient and physician interviews, and data from SUMMIT Part 1 we believe our MS2D2 is a reliable, valid and fit-for-purpose PROM. The MS2D2 Total Symptom Score (“TSS”) is comprised of 11 items, and scored on a 0-110 scale. Pending alignment with the FDA regarding MS2D2 scoring, a comparison of week 24 mean absolute change from baseline in MS2D2 TSS between bezuclastinib and placebo will serve as the measurement of the primary endpoint of the SUMMIT Part 2 study.

Previous wording

In December 2023, at the 2023 ASH meeting, we reported positive clinical data from Part 1 of the APEX trial. As of the data cutoff date of September 25, 2023, 32 patients had been treated in Part 1 at one of four dose levels (50 mg BID, 100 mg BID, 200 mg BID or 400 mg QD). Patients were enrolled with the following sub-types: seven patients with ASM, 23 patients with SM-AHN, and two patients with MCL. As of the cut-off date of September 25, 2023, 32 patients enrolled were evaluated for signs of clinical activity and 27 patients were evaluable for response per the modified IWG-MRT-ECNM criteria. An objective response rate ("ORR") of 52% (including complete remission (“CR”), CR with partial hematologic remission (“CRh”), partial remission (“PR”)) was achieved, including a 56% ORR for TKI-treatment-naïve patients. An ORR of 75% was achieved by pure pathological response (“PPR”) criteria, including an ORR of 86% for TKI-treatment-naïve patients. All patients receiving the 100mg BID achieved PR or better and remain on trial with 3 patients at ≥ 30 cycles of treatment. The 150mg QD dose selected for APEX Part 2 is expected to deliver patient exposures consistent with Part 1. An additional APEX cohort was also initiated in the third quarter of 2023 and is designed to allow concomitant administration of bezuclastinib with azacitadine in patients with SM with an associated hematologic neoplasm.

In April 2023, we reported preclinical data at the American Association for Cancer Research (“AACR”) 2023 Annual Meeting providing the first published evidence of CGT4859 a reversible, selective FGFR2 inhibitor with coverage of activating and emerging resistance mutations that spares inhibition of FGFR1. Preclinical data demonstrate a profile that delivers equipotent coverage across both key gatekeeper and molecular brake mutations (V564X, N549X) in FGFR2, while avoiding any evidence of FGFR1-linked hyperphosphatemia at efficacious plasma concentrations. In October 2023, we presented updated preclinical data at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics. Preclinical data demonstrate a profile that exhibits low namomolar potency on WT FGFR2 and FGFR2 mutations and is selective against the kinome, as well as a panel of channels and receptors. Exploratory pharmacokinetics studies conducted across species showed CGT4859 to be a low-clearance compound with high oral bioavailability. Further, in a mutant-driven mouse model, CGT4859 demonstrated dose-responsive tumor growth inhibition with complete regressions at 5 mg/kg PO, and was well-tolerated. In addition, as a reversible inhibitor, the Cogent program retains enzymatic potency against potential cysteine 491 mutations. We have selected our FGFR2 clinical candidate, CGT4859. IND-enabling studies are on-going, and we expect to initiate a clinical trial by the end of 2024.

Our research team is also advancing a novel, ErbB2 mutant program, which is focused on actionable and underserved mutations in a variety of solid tumor indications. In April 2023, we reported preclinical data at AACR describing a series of novel compounds which potently inhibit several key ErbB2 mutations, including YVMA insertions, while sparing inhibition of EGFR. An exemplar compound from these series demonstrates advantages versus tucatinib, an approved benchmark compound, on tumor growth inhibition in a peripheral ErbB2 L755S driven mutant model, as well as in an ErbB2 driven intracranial model. Recent program advances with a novel chemotype have further improved ErbB2 mutational potency and selectivity and improved human whole blood stability to nearly 24 hours, suggesting a favorable profile for optimal clinical efficacy. Updated data was presented in November 2023 at the San Antonio Breast Cancer Symposium (“SABCS”) and at AACR in April 2024. The updated data presented shows that CGT4255 demonstrated low nM potency against ErbB2 wild-type and oncogenic ErbB2 mutations with 100-fold selectivity over wild-type-EGFR. In addition to impressive selectivity across a broad range of kinases, receptors and ion channels, CGT4255 has exceptional half-life in human whole blood and liver cytosol fractions. Dose ascending PK data in mice showed low clearance and high oral bioavailability at all doses, with best-in-class 80% brain penetrance at 100 mg/kg. Maximum inhibition of pErbB2 was observed at a 30 mg/kg PO dose in both NIH/3T3 ErbB2-YVMA and ErbB2-L755S tumor models, with complete regressions at 100 mg/kg PO BID in the NIH3T3 ErbB2-L755S TGI model and was well tolerated. These advances continue to highlight a favorable profile for optimal clinical efficacy. We selected our ErbB2 clinical candidate and expect to initiate IND-enabling studies in mid-2024.
