- With rapid enrollment in Phase 3 trial, the company expects to report topline data in first quarter of 2016, ahead of schedule
- Topline data from ongoing pivotal Phase 2b clinical trial also expected to be reported earlier than planned
BURLINGTON, Mass., July 29, 2015 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today announced that it has completed enrollment of 486 patients in the Phase 3 clinical trial of its lead compound FX006 approximately three months earlier than anticipated, and the company now plans on reporting topline data from this trial in the first quarter of 2016. This study will complete the requisite clinical package for the New Drug Application (NDA) submission of FX006. The topline clinical data readout from the company's ongoing Phase 2b clinical trial is expected in September 2015, approximately two months ahead of schedule.
FX006 is Flexion's novel, non-opioid, sustained-release, intra-articular (IA) (within the joint) formulation of triamcinolone acetonide (TCA). FX006 is designed to treat patients with moderate to severe osteoarthritis (OA) pain of the knee and is intended to provide substantial and persistent pain relief while avoiding systemic side effects. OA of all joints afflicts more than 27 million adults in the U.S. and 100 million worldwide.
Michael Clayman, M.D., Flexion Therapeutics' President and Chief Executive Officer, said, "We believe the completion of enrollment in this Phase 3 trial positions FX006 ahead of competitive development programs in the U.S. targeting osteoarthritis of the knee, and assuming positive data from both pivotal trials, we will submit an NDA in the second half of 2016 to the FDA for regulatory approval."
Harry E. Rubash, M.D., Chief of the Department of Orthopaedic Surgery at Massachusetts General Hospital commented, "I believe the rapid enrollment in this trial is indicative of the unmet medical need in osteoarthritis therapy. Intra-articular corticosteroids are effective in temporary relief of osteoarthritis symptoms and enhancement of their effect with sustained residence in the joint could constitute a therapeutic advance."
About the Phase 3 Trial of FX006 in OA of the Knee
The randomized, double-blind Phase 3 trial is being conducted at over 40 centers worldwide. The 486 enrolled patients have been randomized to one of three treatment groups (1:1:1) and treated with a single IA injection of normal saline (placebo), 40 mg of FX006 or 40 mg of TCA (the current standard of care). Each patient is being evaluated for efficacy and safety at seven outpatient visits over 24 weeks after receiving an injection. The primary objective of this study is to assess the magnitude and duration of pain relief of FX006 at 12 weeks against placebo. The secondary objectives of this study are to assess the effect of FX006 on the magnitude and duration of pain relief relative to immediate-release TCA and the effect of FX006 on function, responder status, global impressions of change, stiffness and consumption of analgesic medications relative to both controls.
FX006 is a potential 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, approximately 600 patients have been treated with FX006 in clinical trials. 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.
