ACT Biotech files SPA with FDA for telatinib combination Phase 3 trial for stomach cancer

ACT Biotech, Inc., a biopharmaceutical company focused on the development of highly targeted, oral therapeutics for the treatment of cancer, announced today that it has filed a Special Protocol Assessment (SPA) with the U.S. Food and Drug Administration (FDA) related to a randomized Phase 3 trial of telatinib in combination with chemotherapy for the first-line treatment of patients with advanced stomach cancer. The FDA's SPA program is in place to allow the FDA to review and comment on clinical trial protocols, the data from which will form the primary basis of an efficacy claim for drug registration.

Telatinib is the most selective and highly potent next generation antiangiogenic drug currently in clinical trials and the only antiangiogenic in development for front-line treatment of stomach cancer in combination with chemotherapy. The telatinib Phase 3 multi-center, double-blind, randomized trial will compare telatinib in combination with a standard regimen of chemotherapy versus chemotherapy alone in advanced stomach cancer patients. 

"The patient benefit observed from telatinib treatment in our recently completed Phase 2 trial in the same patient population with the same chemotherapy regimen compelled us to advance rapidly into a registration program," said Ali Fattaey, Ph.D., chief operating and scientific officer, ACT Biotech. "Rapid objective tumor responses in two thirds of patients, strong evidence of antiangiogenic activity, an increase in survival over historical controls, and excellent safety in combination with chemotherapy all suggest that telatinib could become an important option for patients with this deadly disease."

If the Phase 3 trial analysis agreed upon in the SPA is positive, the data would then provide the basis for the filing of a U.S. New Drug Application (NDA) for marketing approval of telatinib for the treatment of metastatic stomach cancer. ACT has also received feedback on the Phase 3 trial design from the European Medicines Agency (EMA) and will pursue a global development program.

Previously, a broad Phase 1 program established not only the safety and potent activity of single agent telatinib, but also demonstrated that telatinib can be combined with taxane, platinum, fluoropyrimidine and topoisomerase chemotherapies at full dose, with no required pauses in treatment. To date, 300 patients have been treated with telatinib as monotherapy or in combination with chemotherapy. The ability to combine with chemotherapy at full, uninterrupted dose has been difficult to achieve with first generation molecules, and telatinib may be well positioned for broad applicability in major solid tumor markets.
