CAMBRIDGE, Mass. and BOULDER, Colo., March 15, 2022 (GLOBE NEWSWIRE) -- Cogent Biosciences, Inc. (Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, today announced financial results for the fourth quarter and year ended December 31, 2021.

“In 2021, Cogent achieved substantial progress toward our goal of establishing bezuclastinib as a best-in-class KIT mutant inhibitor for systemic mastocytosis and gastrointestinal stromal tumor (GIST) patients,” said Andrew Robbins, President and CEO of Cogent Biosciences. “All three late-stage bezuclastinib clinical trials are actively enrolling patients, and we look forward to presenting initial clinical data from APEX in the first half of 2022. In addition, we are excited about the progress the Cogent Research Team has made to date and look forward to sharing further details on bezuclastinib, as well as our growing portfolio, at our upcoming R&D Investor Event.”

Key Clinical, Research and Corporate Highlights

• Cogent’s highly potent and selective KIT mutant inhibitor, bezuclastinib, is now under investigation in three late-stage clinical trials:
  • APEX: on track for initial clinical data readout in the first half of 2022
    Cogent is currently enrolling APEX, a global, multicenter, Phase 2 clinical trial of bezuclastinib in patients with Advanced Systemic Mastocytosis (AdvSM) and expects to report initial clinical data at a scientific conference during the first half of 2022, including levels of serum tryptase, a validated biomarker of mast cell activity. Learn more about the APEX trial at cogentclinicaltrials.com/APEX.
  • SUMMIT: initiated in patients with Nonadvanced Systemic Mastocytosis (NonAdvSM)
    Cogent is currently enrolling SUMMIT, a randomized, double-blind, placebo-controlled, global, multicenter, Phase 2 clinical trial. The study is designed to explore the safety and efficacy of bezuclastinib in patients with moderate to severe Indolent Systemic Mastocytosis (ISM) or Smoldering Systemic Mastocytosis (SSM). Learn more about the SUMMIT trial at cogentclinicaltrials.com/SUMMIT.
  • PEAK: initiated in patients with Gastrointestinal Stromal Tumors (GIST)
    During the fourth quarter of 2021, Cogent initiated and now is currently enrolling PEAK, a randomized, open-label, global, Phase 3 clinical trial. The PEAK study is designed to explore the efficacy of bezuclastinib in combination with sunitinib compared to sunitinib alone in patients with locally advanced, unresectable or metastatic GIST who have received prior treatment with imatinib. Learn more about the PEAK trial at cogentclinicaltrials.com/PEAK.

• Preclinical data presented during the third quarter of 2021 highlights bezuclastinib as a potent KIT inhibitor with minimal CNS penetration and which avoids PDGFR inhibition:
  • Cogent presented preclinical data providing further evidence of bezuclastinib as a differentiated, potent, and selective KIT mutant inhibitor with minimal brain penetration while avoiding inhibition of PDGFR isoforms. These data were presented in a virtual poster at the 2021 AACR-NCI-EORTC Virtual International Conference on Molecular Targets and Cancer Therapeutics.

• Cogent Research Team created to generate robust pipeline of potential best-in-class small molecules
  • Cogent Research Team: In 2021, we founded a highly-experienced Boulder-based discovery and research team focused on pioneering best-in-class, small molecule therapeutics to expand Cogent's pipeline. John Robinson, PhD, leads the Cogent Research Team, which has grown to over 35 employees and will move into its newly-built, state-of-the-art research facility in Boulder this spring.

• R&D Investor Event: Cogent will host an R&D Investor Event at which the Cogent Research Team will share additional nonclinical data demonstrating bezuclastinib’s potential as a best-in-class KIT mutant inhibitor, outline its strategy and focus to create best-in-class small molecules, and present early data from its growing pipeline of novel, small molecule targeted therapy programs including FGFR2. The R&D Investor Event will be a live webcast on Friday, April 8, 2022 beginning at 4:05 p.m. ET. On the day of the webcast, the American Association for Cancer Research (AACR) poster presentations will be made available through the AACR conference website at 1:00 p.m. ET. Additional details about the R&D Investor Event will be shared in the coming weeks.
  

• Successfully bolstered Cogent balance sheet utilizing our At-The-Market (ATM) Program: In Q4 2021, pursuant to Cogent’s ATM program, we completed the sale of common shares to certain institutional investors for net proceeds of approximately $38 million with offering prices ranging between $9.25 and $10.30 per share.

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 to bezuclastinib, the Cogent Research Team is developing a portfolio of novel targeted therapies to help patients fighting serious, genetically driven diseases. Cogent Biosciences is based in Cambridge, MA and Boulder, CO. Visit our website for more information at www.cogentbio.com. Follow Cogent Biosciences on social media: Twitter and LinkedIn.
