Bezuclastinib in GIST Presented detailed clinical data from the Phase 3 PEAK trial evaluating bezuclastinib in combination with sunitinib vs. sunitinib monotherapy in patients with imatinib-resistant or intolerant Gastrointestinal Stromal Tumors (GIST) at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting. As of the cutoff date, September 30, 2025, the bezuclastinib combination demonstrated a substantial and highly statistically significant clinical benefit on the primary endpoint of PFS, reducing risk of disease progression or death compared to the current standard of care by 50% (hazard ratio of 0.50, 95% CI: 0.39 – 0.65). mPFS, as assessed by blinded independent central review, was 16.5 months for the bezuclastinib combination vs. 9.2 months for sunitinib monotherapy. Additionally, the bezuclastinib combination demonstrated an unprecedented ORR in imatinib-resistant/intolerant patients, with 46% of patients treated with the bezuclastinib combination achieving an objective response compared to 26% of patients treated with sunitinib. Data for overall survival remains immature. Based on the ongoing patients receiving treatment on the bezuclastinib arm as of March 31, 2026, the mean duration of treatment for the bezuclastinib combination is estimated to be 21.4 months. Announced the initiation of a single-arm, 40 patient extension cohort of the PEAK trial investigating the safety and efficacy of the bezuclastinib combination in first-line GIST patients with KIT exon 9 primary mutations who have received limited or no imatinib treatment. This cohort is designed to prospectively measure ORR and PFS in this patient population, building upon the 25.1 month mPFS reported in a subgroup of 32 patients with detectable exon 9 mutations treated with the bezuclastinib combination in the Phase 3 PEAK trial. Announced FDA acceptance of the New Drug Application (NDA) with priority review for bezuclastinib in combination with sunitinib in patients with GIST who have received prior treatment with imatinib. Bezuclastinib in Systemic Mastocytosis Announced submission of the NDA for bezuclastinib in Advanced Systemic Mastocytosis (AdvSM). Presented detailed data from the pivotal APEX trial at the 2026 European Hematology Association (EHA) Congress. As of the March 31, 2026 data cutoff, 81 AdvSM patients were treated with 150 mg of bezuclastinib, including 57 patients with SM-AHN, 11 patients with ASM and 13 patients with MCL. The primary endpoint of response per mIWG-MRT-ECNM was assessed on 68 evaluable patients and showed 65% ORR (CR+CRh+PR+CI), including 57% of patients who achieved CR, CRh or PR as best response. Announced completion of enrollment in the “avapritinib switch” SUMMIT extension trial with preliminary results expected by end of 2026. Presented preclinical data from the novel JAK2 V617F program at EHA. The poster highlighted CGT1145, a potent inhibitor of the JAK2 V617F mutation with >100x selectivity over JAK2 WT and the JAK1/3 isoforms, along with high oral bioavailability and low clearance across species. CGT1145 has the potential to eradicate JAK2 V617F myeloproliferative neoplasm propagating cells and induce molecular remission with improved hematologic tolerability. Anticipated Upcoming Milestones Potential FDA approval of bezuclastinib in GIST – PDUFA date of November 30, 2026 Potential FDA approval of bezuclastinib in NonAdvSM – PDUFA date of December 30, 2026 Submit Investigational New Drug (IND) applications for CGT1815, Cogent’s novel, selective pan-KRAS(ON) inhibitor, and CGT1145, Cogent’s novel, selective JAK2 V617F inhibitor Complete dose escalation for CGT4255, Cogent’s CNS-penetrant, selective mutant ErbB2 inhibitor Second Quarter 2026 Financial Results Cash Position: As of June 30, 2026, Cogent had cash, cash equivalents and marketable securities of $792.3 million. The company expects its existing cash, cash equivalents and marketable securities, with the $73.6 million gross proceeds from shares sold through the Company’s at-the-market (ATM) facility after the end of the quarter, will be sufficient to fund its operating expenses and capital expenditure requirements into late 2028, including through potential FDA approvals of bezuclastinib for GIST, NonAdvSM and AdvSM and early commercial launch activities. R&D Expenses: Research and development expenses were $70.8 million for the second quarter of 2026 as compared to $62.2 million for the second quarter of 2025. The increase was primarily driven by costs to support the SUMMIT, PEAK and APEX clinical programs, regulatory activities associated with potential approvals of bezuclastinib, continued investment in the company's early-stage research pipeline, and pre-approval manufacturing costs that will be capitalized following anticipated FDA approval. R&D expenses include non-cash stock compensation expense of $8.6 million for the second quarter of 2026 as compared to $5.0 million for the second quarter of 2025. G&A Expenses: General and administrative expenses were $31.8 million for the second quarter of 2026 as compared to $13.4 million for the second quarter of 2025. The increase was primarily driven by continued investments in commercial readiness, including personnel and infrastructure to support the anticipated launch of bezuclastinib, as well as overall organizational growth. G&A expenses include non-cash stock compensation expense of $8.5 million for the second quarter of 2026 as compared to $4.8 million for the second quarter of 2025. Net Loss: Net loss was $96.4 million for the second quarter of 2026 as compared to a net loss of $73.5 million for the same period of 2025. Inducement Grants Under Nasdaq Listing Rule 5635(c)(4) Cogent also announced today that, on August 4, 2026, the Compensation Committee of Cogent’s Board of Directors, made up entirely of independent directors, approved the grants of “inducement” equity awards to 59 new employees under the company’s 2020 Inducement Plan with grant dates of August 4, 2026 and August 10, 2026. The awards were approved in accordance with Listing Rule 5635(c)(4) of the corporate governance rules of the Nasdaq Stock Market. The employees received, in the aggregate, (i) nonqualified options to purchase 226,700 shares of Cogent common stock and (ii) 189,700 restricted stock units (RSUs). Each option has a 10-year term, an exercise price equal to the closing price of Cogent’s common stock on the grant date, and a 4-year vesting schedule with 25% vesting on the 1-year anniversary of the grant date and the remainder vesting in equal monthly installments over the subsequent 36 months, provided such employee remains employed through each such vesting date. The RSUs vest annually in equal installments over 4 years from the grant date, provided such employee remains employed through each such vesting date. About Cogent Biosciences, Inc.
