BURLINGTON, Mass., Dec. 26, 2019 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today announced that the U.S. Food and Drug Administration (FDA) has approved a supplemental New Drug Application (sNDA) to update the product label for ZILRETTA (triamcinolone acetonide extended-release injectable suspension) for the treatment of osteoarthritis (OA) knee pain.
Key elements of the label update include:
“We are very pleased with the new product label as it achieves our primary goal of removing unclear language pertaining to repeat administration, which we believe was potentially confusing to patients, physicians and payers alike,” said Michael Clayman, M.D., President and Chief Executive Officer of Flexion. “In addition, we are gratified by the inclusion of safety data from our repeat administration trial and the removal of the inappropriate comparator statement. We believe the updated label supports our goal of seeing ZILRETTA become the leading intra-articular therapy for managing OA knee pain.”
Added John Richmond, M.D., Medical Director for Network Development, New England Baptist Hospital, “As both a clinician and a ZILRETTA patient, I have firsthand experience with the significant magnitude and duration of pain relief it can provide to people confronting knee OA. ZILRETTA is an invaluable non-opioid option for managing chronic OA knee pain, and it is encouraging to see a new product label that better informs clinical decision making.”

Flexion's management will host a conference call at 8:00 a.m. on Friday, December 27, 2019 to discuss the approval. The dial-in number for the conference call is (855) 770-0022 for U.S. participants and (908) 982-4677 for international participants, with Conference ID # 5887398.

About ZILRETTA
On October 6, 2017, ZILRETTA was approved by the U.S. FDA as 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. The pivotal Phase 3 trial on which the approval of ZILRETTA was based showed that ZILRETTA significantly reduced knee pain for 12 weeks, with some people experiencing pain relief through Week 16.
About Osteoarthritis (OA) of the Knee
OA, also known as degenerative joint disease, affects more than 30 million adults living in the U.S. 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, approximately five million OA patients receive either an immediate-release corticosteroid or hyaluronic acid intra-articular injection to manage their knee pain.
