Flexion Therapeutics Announces Issuance Of U.S. Composition Of Matter Patent For Lead Candidate FX006
BURLINGTON, Mass., Sept. 9, 2014 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today announced that the U.S. Patent and Trademark Office has issued a composition of matter patent (No. 8828440), entitled "Corticosteroids for the Treatment of Joint Pain," which provides coverage for FX006, the company's lead clinical product candidate. FX006 is a novel, non-opioid, sustained-release, intra-articular (IA) formulation of triamcinolone acetonide (TCA). The patent describes and claims an injectable formulation comprised of controlled or sustained-release microparticles that contain TCA in a poly(lactic-co-glycolic) acid co-polymer (PLGA) matrix.
"The issuance of this patent marks an important milestone for Flexion as it directly protects our lead product, FX006, for a prolonged period of time and provides a critical foundation for its eventual commercialization," said Michael Clayman, M.D., President and CEO. "Based on the available clinical data to date, we are enthusiastic about the prospect of FX006 playing an important role in the treatment of patients with osteoarthritis (OA) of the knee. This patent, together with last week's announcement on the planned start of our pivotal Phase 3 clinical trial for FX006 a year ahead of schedule, brings us closer to realizing the potential of this novel therapy."
FX006 is designed to provide prolonged pain relief for the treatment of OA of the knee, while potentially avoiding untoward systemic effects associated with immediate-release steroids. Last year Flexion announced the results of a Phase 2b OA dose-ranging trial that demonstrated that FX006 provided superior pain relief compared to the standard of care IA immediate-release steroid. Flexion also recently announced positive topline clinical trial results from a Phase 2a synovial fluid pharmacokinetic (PK) trial of FX006, which demonstrated, for the first time, that a single IA injection of FX006 can provide therapeutic concentrations of FX006 in joint fluid for at least 12 weeks. A pivotal Phase 2b confirmatory clinical trial for FX006 is currently enrolling patients and topline data are expected in the first half of 2015. Based on a recent meeting with the U.S. Food and Drug Administration (FDA) to review the clinical development program for FX006, Flexion earlier this month announced plans to accelerate the initiation of a pivotal Phase 3 clinical trial for FX006 to late 2014 and expects to complete the trial by the second half of 2015. The Phase 3 trial will be an international, multi-center, randomized, blinded, single-dose study in 462 patients with OA of the knee. It will have three separate arms that include a 40 mg dose of FX006, placebo, and a 40 mg dose of TCA. The primary objective of the trial will be to provide the second pivotal efficacy dataset against placebo for an NDA submission. In addition, the trial will provide a key comparative dataset against the current standard of care, immediate-release TCA, and could potentially support a commercial advantage in the launch of the drug.
