Xynomic Pharmaceuticals Holdings, Inc. has announced that it has filed an application with the U.S. Food and Drug Administration (U.S. FDA) seeking Fast-Track designation for its drug candidate abexinostat as a monotherapy for the treatment of relapsed or refractory follicular lymphoma (r/r FL). Fast-Track designation is designed to aid in the development and expedite the review of drug candidates, which show promise in treating a serious or life-threatening disease, and address an unmet medical need. A drug candidate that receives Fast-Track designation is eligible for more frequent meetings and correspondences with the U.S. FDA and potential accelerated or priority review and more. The U.S. FDA will review the request and attempt to make a decision within 60 days. Xynomic is conducting a Phase 2 trial to test abexinostat as a single agent in patients with r/r FL. Designed as a single arm trial, this trial will enroll approximately 120 patients in the U.S. and Europe who have undergone at least three lines of therapy to test abexinostat as a fourth line monotherapy. The U.S. FDA has already granted Fast-Track designation to abexinostat, in combination with pazopanib, as a first- or second-line treatment of renal cell carcinoma (“RCC”). A global, randomized pivotal Phase 3 trial is underway to test abexinostat combined with pazopanib as a first- or second-line therapy in patients with locally advanced or metastatic RCC.
