BURLINGTON, Mass., April 29, 2015 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today announced that the U.S. Department of Defense ("DoD") awarded the company a grant1 worth approximately $2 million to conduct a Phase 2 clinical trial investigating FX006 as treatment for osteoarthritis ("OA") pain in active military and medically retired veterans with post-traumatic OA of the knee. FX006 is a steroid, triamcinolone acetonide or TCA, formulated for sustained-release, delivered by intra-articular ("IA" or "in the joint") injection for patients with OA pain of the knee. Flexion announced in February that dosing had begun in a Phase 3 clinical trial of FX006 as a treatment for pain associated with OA of the knee.
"We are pleased that the U.S. DoD has awarded Flexion a grant to study FX006 in military personnel and veterans who have experienced trauma to the knee and are looking for potentially better options to manage pain related to their knee OA," said Michael Clayman, M.D., Flexion Therapeutics' President and Chief Executive Officer. "We are honored to be working toward meeting the medical needs of our U.S. soldiers and to have the agency's support to further investigate our lead drug candidate in this capacity."
The DoD-funded trial is a single-center, double-blind, randomized, parallel group, proof-of-concept study, which plans to enroll a total of 124 male and female active and former service members between the ages of 20 and 45 years. The primary objective of this study will be to assess the analgesic effect of a single IA injection of 40 mg of FX006 relative to commercially available immediate-release TCA in active military and medically retired patients with moderately symptomatic post-traumatic OA of the knee. The primary endpoint is the average change from baseline in the weekly mean of the average daily (24-hour) pain intensity scores over weeks 5 to 10. The study is also designed to assess the effect of FX006 on function, responder status, global impressions of change, stiffness and consumption of analgesic medications and to assess the safety and tolerability of a single IA injection of 40 mg FX006 relative to commercially available immediate-release TCA.
FX006 is a first-in-class injectable, sustained-release, IA steroid treatment for patients with moderate to severe OA pain. FX006 was specifically designed to address the limitations of current IA therapies by providing long-lasting, local analgesia while avoiding systemic side effects. To date, over 440 patients have been treated with FX006. In a completed Phase 2b dose-ranging clinical trial, FX006 has demonstrated clinically meaningful and significantly better pain relief compared to the current injectable standard of care, TCA. In two Phase 2a synovial fluid pharmacokinetic studies, a single IA injection of FX006 demonstrated therapeutic concentrations of drug in joint fluid for at least 12 weeks. FX006 is currently being studied in pivotal Phase 2b and Phase 3 clinical trials, which are designed to provide the required data for FX006 to be submitted for regulatory approval by the U.S. Food and Drug Administration.
