WALTHAM, Mass. and BOULDER, Colo., Oct. 24, 2025 (GLOBE NEWSWIRE) -- Cogent Biosciences, Inc. (Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, today announced updated preclinical data from the company’s potent and selective pan KRAS(ON) inhibitor in a poster presentation at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics taking place in Boston, MA, October 22-26, 2025.

“We are excited today to share updated data from our pan KRAS(ON) program which demonstrates a potential best-in-class profile for our lead molecule,” said Andrew Robbins, Cogent’s President and Chief Executive Officer. “We look forward to advancing this program with the goal of filing an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) in 2026.”

Title: Identification of CGT1263, a Potent KRAS Inhibitor with Selectivity for Mutant KRAS over HRAS and NRAS
Session Date and Time: Poster Session B, Friday, October 24, 2025 – 12:30 p.m. – 4:00 p.m. ET
Poster Number: B024
Abstract Number: B024

Mutations in KRAS are among the most prevalent mutations found in cancer, occurring most often in colorectal cancer, non-small cell lung cancer and pancreatic cancer. The poster presented today describes Cogent’s internally developed KRAS(ON/OFF) inhibitor CGT1263, showing clear selectivity over HRAS and NRAS, with picomolar (pM) activity across a broad panel of KRAS mutant cell lines. In addition, the poster also characterizes CGT1815 (the prodrug of CGT1263), which is designed to optimize human pharmacokinetic performance, supported by pharmacokinetics data from both CGT1815 and CGT1263 across multiple species. Finally, the poster highlights that CGT1815 demonstrates superior efficacy in KRAS G12D and KRAS G12V tumor growth inhibition studies when compared to RMC-6236.

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. The company also has an ongoing Phase 1 study of its novel internally discovered FGFR2/3 inhibitor. 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, PI3Kα and KRAS. Cogent Biosciences is based in Waltham, MA and Boulder, CO. Visit our website for more information at www.cogentbio.com .
