(Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation (BTD) for bezuclastinib in combination with sunitinib for patients with Gastrointestinal Stromal Tumors (GIST) who have received prior treatment with imatinib. “We are excited to announce this Breakthrough Therapy Designation which recognizes the potential for the bezuclastinib combination to substantially improve upon the currently available treatment options for patients with imatinib-resistant GIST,” said Andrew Robbins, Cogent’s President and Chief Executive Officer. “We look forward to the continued collaboration with the FDA as we work to bring the first new treatment option in over twenty years to this patient population.” This Breakthrough Therapy Designation is based on results from the PEAK trial which demonstrated a substantial and highly statistically significant clinical benefit on the primary endpoint of progression free survival (PFS), reducing risk of disease progression or death compared to the current standard of care by 50% (hazard ratio of 0.50, 95% CI: 0.39 – 0.65). mPFS, as assessed by blinded independent central review, was 16.5 months for the bezuclastinib combination vs. 9.2 months for sunitinib monotherapy. The combination was well tolerated, and no new safety risks were observed when compared to the known safety profile of sunitinib. Breakthrough Therapy Designation is intended to expedite the review of medicines that treat a serious or life-threatening condition and have shown clinical evidence indicating the potential for substantial improvement over available therapies. Earlier this month, the FDA agreed to accept Cogent’s NDA under the FDA’s Real-Time Oncology Review (RTOR) program which allows an applicant to pre-submit components of its NDA to allow the FDA to review clinical trial data before the complete filing is submitted and aims to provide a more efficient review process to ensure safe and effective treatments are available to ...
