BURLINGTON, Mass., Dec. 07, 2017 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) announced today the enrollment of the first patient in a clinical trial to evaluate the pharmacokinetics (PK) and safety of concurrent injections of ZILRETTA (triamcinolone acetonide extended-release injectable suspension) in patients with bilateral osteoarthritis (OA) of the knee. The randomized, open-label, Phase 2 study is expected to enroll approximately 24 patients.
The safety and tolerability of a single injection of ZILRETTA has been established through multiple Phase 2 and Phase 3 clinical trials focused on administration in one knee. ZILRETTA received approval from the U.S. Food and Drug Administration on October 6, 2017 for the management of OA knee pain and the company initiated the full commercial launch on November 20, 2017.
We know there are many patients who suffer from bilateral knee OA pain, yet physicians are often reluctant to administer an immediate-release steroid into both knees concurrently due to concerns about systemic exposure, said Michael Clayman, M.D., President and Chief Executive Officer of Flexion. The data from this study are expected to provide insight into ZILRETTAs potential to further demonstrate lower plasma concentrations from two injections compared with traditional immediate-release steroids.
The study will compare plasma PK profiles after concurrent injections of ZILRETTA versus immediate-release triamcinolone acetonide in crystalline suspension (TAcs). Patients will be randomized and treated with bilateral injections of either ZILRETTA (total dose of 64 mg) or TAcs (total dose of 80 mg). Each patient will be evaluated for six weeks following injection. Flexion expects to report top-line results of the study in the first half of 2018.

About 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 ageof physician-diagnosed knee OAhas 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.
