BURLINGTON, Mass., Dec. 18, 2017 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) announced today that it has enrolled the first patient in a clinical trial to evaluate the pharmacokinetics and safety of ZILRETTATM (triamcinolone acetonide extended-release injectable suspension) in patients with osteoarthritis (OA) of the shoulder or hip. Known as the "SHIP" study, the randomized, open-label, Phase 2 trial is expected to recruit approximately 48 patients in total, including 24 patients with OA of the shoulder and 24 patients with OA of the hip.
"While ZILRETTA has been approved for use in the knee, this is the first trial to investigate ZILRETTA in other large joints," said Michael Clayman, M.D., President and Chief Executive Officer of Flexion. "We are looking forward to the readout from this study, and the findings will inform our discussions with the U.S. Food and Drug Administration regarding a pathway for potential label expansion of ZILRETTA."
The SHIP study will compare ZILRETTA's pharmacokinetic profile to immediate-release triamcinolone acetonide in crystalline suspension (TAcs) and will also assess the safety and general tolerability of ZILRETTA in OA of the shoulder and OA of the hip. Patients will be randomized and treated with a single intra-articular injection of either ZILRETTA (32 mg) or TAcs (40 mg). Each patient will be evaluated for 12 weeks following injection. Flexion expects to report top-line results of the study in the second half of 2018.

ZILRETTA is the first and only extended-release, intra-articular therapy for patients confronting osteoarthritis-related knee pain. ZILRETTA employs proprietary microsphere technology combining triamcinolone acetonide — a commonly administered, short-acting corticosteroid — with a poly lactic-co-glycolic acid (PLGA) matrix to provide extended pain relief over 12 weeks. ZILRETTA received approval from the U.S. Food and Drug Administration on October 6, 2017 and the company initiated the full commercial launch on November 20, 2017.
About Osteoarthritis (OA) of the Knee
OA, also known as degenerative joint disease, affects more than 30 million Americans and accounts for more than $185 billion in annual expenditures. In 2016, more than 15 million Americans were diagnosed with OA of the knee and the average age of physician-diagnosed knee OA has fallen by 16 years, from 72 in the 1990s to 56 in the 2010s. The prevalence of OA is expected to continue to increase as a result of aging, obesity and sports injuries. Each year, more than 15 million Americans are treated for OA-related knee pain, and approximately five million OA patients receive either an immediate-release corticosteroid or hyaluronic acid intra-articular injection to manage their knee pain.
