Cogent Biosciences Announces Planned 2023 Milestones for Bezuclastinib and Emerging Portfolio of Selective and Potent Targeted Cancer Therapeutics

  • Demonstrate significant progress toward leadership in Systemic Mastocytosis (SM), including mid-year Part 1 results from Phase 2 APEX trial in AdvSM patients and initial clinical data in 2H23 from Phase 2 SUMMIT trial in NonAdvSM patients
  • Rapidly progress bezuclastinib in 2nd-line Gastrointestinal Stromal Tumors (GIST), with planned clinical update from lead-in portion of Phase 3 PEAK trial in 1H23, and expansion to >100 global clinical sites this year
  • Select clinical candidates from ongoing FGFR2-mutant selective and ErbB2-mutant selective programs and disclose two additional novel targeted cancer therapeutic programs this year
  • Company to present at J.P. Morgan 41st annual healthcare conference on Thursday, January 12 at 7:30 a.m. PT / 10:30 a.m. ET

WALTHAM, Mass. and BOULDER, Colo., Jan. 09, 2023 (GLOBE NEWSWIRE) — Cogent Biosciences, Inc. (Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, today highlighted the company’s key 2023 milestones ahead of its presentation at J.P. Morgan’s 41st annual healthcare conference this week.

“We made tremendous progress in 2022 demonstrating bezuclastinib’s differentiated clinical profile in Systemic Mastocytosis while advancing an improved formulation of bezuclastinib through clinical studies that enabled the start of our global Phase 3 GIST trial,” said Andrew Robbins, President and CEO of Cogent Biosciences. “In 2023, we look forward to continuing the rapid development of bezuclastinib toward leadership positions in both Systemic Mastocytosis and GIST, while we enhance our impressive, growing portfolio of targeted cancer therapeutics. By the end of 2023, we expect to have a portfolio of five distinct programs which will position us as a leader in precision medicine.”

In 2023, the Company plans to achieve the following milestones:

Bezuclastinib – Systemic Mastocytosis (SM)

  • Phase 2 APEX trial – announce results from planned Part 1 analysis including approximately 25-30 AdvSM patients in mid-2023, enabling dose selection for Part 2 trial expansion.
  • Phase 2 SUMMIT trial – present initial clinical data in patients with NonAdvSM in the second half of 2023. Clinical results will include safety/tolerability, pharmacokinetics and measures of clinical activity.
  • Initiate clinical investigation of bezuclastinib in SM patients with associated hematologic neoplasms (SM-AHN), allowing for concomitant use of AHN-directed therapies.

Bezuclastinib – Gastrointestinal Stromal Tumors (GIST)

  • Present updated clinical results from refractory GIST patients in the lead-in cohort of the Phase 3 PEAK trial of the pan-KIT mutant regimen, bezuclastinib plus sunitinib, during the first half of 2023.
  • Enrollment in the Phase 3 PEAK trial for 2nd-line GIST patients remains on track, with expansion to over 100 global clinical sites expected before the end of this year.

Preclinical Pipeline

  • Select FGFR2-mutant selective clinical candidate and initiate IND-enabling GLP toxicology studies in the first half of 2023. This program is designed as a potential best-in-class, reversible, FGFR1-sparing, potent pan-FGFR2 mutant inhibitor that includes coverage of both key gatekeeper and molecular brake mutations (V564I, N549K).
  • Select ErbB2-mutant selective clinical candidate in the second half of 2023. This program is designed as an EGFR-sparing, CNS-penetrant ErbB2 inhibitor that includes coverage of key mutations (YVMA, S310F, V842I, L755S) inadequately addressed by currently approved therapies.
  • Present initial preclinical data on two additional novel target programs with best-in-class potential out of the Cogent Research Team’s labs during 2023.

JPM Presentation Details

Morgan 41st Annual Healthcare Conference in San Francisco on Thursday, January 12, 2023, beginning at 7:30 a.m. PT (10:30 p.m. ET).

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 (SM), 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 initially targeting FGFR2 and ErbB2. Cogent Biosciences is based in Waltham, MA and Boulder, CO. Visit our website for more information at www.cogentbio.com. Follow Cogent Biosciences on social media: Twitter and LinkedIn. Information that may be important to investors will be routinely posted on our website and Twitter.
