Cogent Biosciences Share Up After Positive Initial Clinical Data From Bezuclastinib Trial
Jun 10, 2022 By MarketDepth
Cogent Biosciences, Inc. (NASDAQ: COGT) is up more than 60% after the Company announced positive initial data from its ongoing Phase 2 APEX clinical trial evaluating the selective KIT D816V inhibitor bezuclastinib in patients with advanced systemic mastocytosis (AdvSM). The data are being presented today in a poster presentation at the 2022 European Hematology Association (EHA) Congress in Vienna, Austria.
“Advanced systemic mastocytosis is a severe, debilitating hematologic disorder and physicians and patients remain in search of more effective and better tolerated treatment options to fight this disease. I am very impressed with the early, encouraging results presented today from the APEX study. If results like these can be shown in a larger set of patients with AdvSM, I believe bezuclastinib has the potential to help us take a big step forward in treating systemic mastocytosis patients.”
Daniel DeAngelo, M.D., Ph.D., Chief of the Division of Leukemia at the Dana-Farber Cancer Institute and APEX clinical trial investigator
APEX is a global, open-label, multi-center, two-part Phase 2 clinical trial in patients with AdvSM evaluating the safety, efficacy, pharmacokinetic, and pharmacodynamic profiles of bezuclastinib. As of the data cutoff date of May 24, 2022, 11 patients had been treated in Part 1 at one of four dose levels (50 mg BID, 100 mg BID, 200 mg BID or 400 mg QD). The median age of patients at study entry was 70 years (ranging from 48-87 years).
“We are very excited to present initial clinical data from the APEX study of bezuclastinib in advanced systemic mastocytosis. These results reinforce the hypothesis that a potent, selective KIT D816V inhibitor with limited CNS penetration has the potential to provide meaningful clinical activity to all systemic mastocytosis patients, without the tolerability challenges seen with other available treatment options. Based on these results, we expect to accelerate our timelines and investment and look forward to providing another APEX clinical update by the end of 2022, and to presenting SUMMIT clinical data in non-advanced systemic mastocytosis (NonAdvSM) patients in the first half of 2023.”
Andrew Robbins, Chief Executive Officer at Cogent Biosciences
