On-track to present additional data from Phase 2 APEX trial by the end of 2022

Initial data from Phase 2 SUMMIT trial & lead-in data from Phase 3 PEAK trial planned for 1H23

Ended 2Q 2022 with $325.6 million, including $172.6 million in gross proceeds from June 2022 public offering, sufficient to fund operations into 2025

CAMBRIDGE, Mass. and BOULDER, Colo., Aug. 09, 2022 (GLOBE NEWSWIRE) -- Cogent Biosciences, Inc. (Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, today reported financial results for the second quarter ended June 30, 2022.

“In the second quarter we achieved a number of important milestones as we continued to advance bezuclastinib and grow the research and development pipeline,” said Andrew Robbins, President and CEO of Cogent Biosciences. “Most notably, we reported positive initial clinical data from our APEX trial that strengthened our belief in bezuclastinib’s potential to provide meaningful clinical activity for systemic mastocytosis patients, without the tolerability challenges seen with other available treatment options. We remain on track to provide another clinical update from this trial by the end of 2022. We are equally excited about the opportunity with bezuclastinib in non-advanced systemic mastocytosis and gastrointestinal stromal tumor (GIST) patients and expect to provide clinical data updates on these programs during the first half of 2023. Based on the positive APEX data, we were able to secure additional financing at the end of the quarter, and we are confident this will support our go forward strategy into 2025.”
