BURLINGTON, Mass., April 13, 2021 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today announced preliminary ZILRETTA (triamcinolone acetonide extended-release injectable suspension) net sales of approximately $24.6 million for the quarter ended March 31, 2021.

“Overall, we were pleased with our commercial performance in the first quarter. ZILRETTA net sales were broadly in line with our expectations, in spite of facing some unexpected delays in intra-articular procedures associated with the rollout of the COVID-19 vaccines and the extended power outages that affected Texas and other key markets in February,” said Michael Clayman, M.D., President and Chief Executive Officer of Flexion Therapeutics. “While the impacts of the COVID-19 pandemic continue to affect patient flows, barring any unforeseen resurgence or outbreaks of more virulent strains, we anticipate 2021 ZILRETTA net sales in the range of $120 to $130 million, reflecting year-over-year growth of approximately 40 to 50 percent. The opportunity ahead of us is tremendous, and we remain tireless in our commitment to make ZILRETTA a leading intra-articular treatment for the millions of patients confronting osteoarthritis knee pain.”

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 OA 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, is the most common form of arthritis affecting more than 32.5 million adults living in the United States. In 2017, approximately 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 a corticosteroid (immediate-release or extended-release) or hyaluronic acid intra-articular injection to manage their knee pain.
