WALTHAM, Mass. and BOULDER, Colo., May 05, 2026 (GLOBE NEWSWIRE) -- Cogent Biosciences, Inc. (Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, today provided a business update and announced financial results for the first quarter ended March 31, 2026.

“2026 is shaping up to be a pivotal year for Cogent,” said Andrew Robbins, Cogent’s President and Chief Executive Officer. “We have two NDAs for bezuclastinib under FDA review and expect to submit a third in the first half of this year. These milestones highlight the breadth of bezuclastinib’s potential across GIST and KIT-driven diseases. With a strong balance sheet, we are focused on completing our commercial build and preparing for multiple potential launches.”

Recent Business Highlights

• Announced details for an oral presentation on May 30 at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting featuring pivotal data from the Phase 3 PEAK trial in patients with Gastrointestinal Stromal Tumors (GIST) who have received prior treatment with imatinib

• Announced submission of the company’s New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for bezuclastinib in patients with GIST who have received prior treatment with imatinib. Based on the positive results from the PEAK trial, the bezuclastinib NDA was submitted under the FDA’s Real-Time Oncology Review (RTOR) program, which is intended to enable a more streamlined review process. Bezuclastinib was also granted Breakthrough Therapy Designation as a treatment for GIST earlier in 2026.
  
  
• Announced the FDA accepted its NDA for bezuclastinib in patients with NonAdvanced Systemic Mastocytosis (NonAdvSM) and assigned a Prescription Drug User Fee Act (PDUFA) target action date of December 30, 2026
  
  
• Presented six posters with bezuclastinib in patients with NonAdvSM at the 2026 AAAAI annual meeting
  
  
• Initiated Phase 1 studies for both CGT4255, a novel, selective, brain-penetrant ErbB2 inhibitor and CGT6297, a novel, selective and potential best-in-class PI3Ka inhibitor
  
  

Upcoming Milestones

Bezuclastinib

• Submit the APEX NDA in the first half of 2026 for bezuclastinib in patients with Advanced Systemic Mastocytosis (AdvSM)

First Quarter 2026 Financial Results

Cash and Cash Equivalents: As of March 31, 2026, cash, cash equivalents and marketable securities were $866.4 million, which includes net proceeds of $45.7 million from shares recently sold under the Company’s at-the-market (ATM) stock offering as well as non-recurring payments totaling $18.0 million related to annual performance-based bonus compensation and a milestone payment to Plexxikon. Based on our current plans, we expect our existing cash, cash equivalents and marketable securities will be sufficient to fund our operating expenses and capital expenditure requirements into 2028, including the commercialization of bezuclastinib in SM and GIST.

R&D Expenses: Research and development expenses were $75.4 million for the first quarter of 2026 compared to $63.0 million for the first quarter of 2025. The increase was driven by increased early-stage, preclinical and discovery programs as we advance our pipeline of programs into Phase 1 clinical trials and IND-enabling studies, and includes one-time costs associated with the wind down of the FGFR clinical program. R&D expenses include non-cash stock compensation expense of $8.9 million for the first quarter of 2026 as compared to $5.3 million for the first quarter of 2025.

G&A Expenses: General and administrative expenses were $28.2 million for the first quarter of 2026 compared to $11.9 million for the first quarter of 2025. The increase was primarily due to the growth of the organization and activities related to the anticipated commercial launch of bezuclastinib. G&A expenses include non-cash stock compensation expense of $8.0 million for the first quarter of 2026 as compared to $4.8 million for the first quarter of 2025.

Net Loss: Net loss was $97.4 million for the first quarter of 2026 compared to a net loss of $72.0 million for the first quarter of 2025.

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.

Cogent Biosciences is a biotechnology company focused on developing precision therapies for genetically defined diseases. The most advanced clinical program, bezuclastinib, is a selective tyrosine kinase inhibitor that is designed to potently inhibit the KIT D816V mutation as well as other mutations in KIT exon 17. KIT D816V is responsible for driving Systemic Mastocytosis, a serious 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. In addition, the Cogent Research Team is developing a portfolio of novel targeted therapies to help patients fighting serious, genetically driven diseases targeting mutations in ErbB2, PI3Ka, KRAS and JAK2. Cogent Biosciences is based in Waltham, MA and Boulder, CO. Visit our website for more information at www.cogentbio.com.
