Flexion Therapeutics Announces Full Commercial Launch and Nationwide Availability of ZILRETTA™ (triamcinolone acetonide extended-release injectable suspension)

  • Recently approved, non-opioid therapy now available for the management of osteoarthritis knee pain
  • Launch of ZILRETTA commences with full complement of field sales personnel deployed across the U.S.

BURLINGTON, Mass., Nov. 20, 2017 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today announced the full commercial launch of ZILRETTA™ (triamcinolone acetonide extended-release injectable suspension), the company’s new therapy for the management of pain associated with osteoarthritis (OA) of the knee. On October 6, 2017, ZILRETTA was approved by the U.S. Food and Drug Administration, and the product has been available on a limited basis since October 23. Flexion has hired and trained more than 100 field sales representatives, known as Musculoskeletal Business Managers, who are now deployed across the country. 

“We have assembled a remarkable team of Musculoskeletal Business Managers, and last week they concluded their training at the ZILRETTA national launch meeting,” said Michael Clayman, M.D., President and Chief Executive Officer of Flexion. “We have already begun the process of informing and educating physicians about the important role ZILRETTA can play in the management of OA knee pain.  With its extended-release microsphere formulation, we believe ZILRETTA holds the potential to disrupt the current treatment paradigm, and we are thrilled that it is now broadly available for the millions of Americans confronting this relentless disease.”

OA is a progressive and incurable condition and the most common form of arthritis. Its effects may range from intermittent discomfort to the loss of function and severe chronic pain associated with irreversible structural damage. ZILRETTA is the first and only extended-release, intra-articular injection for OA knee pain. It is a non-opioid medicine that employs Flexion's proprietary microsphere technology to provide proven pain relief over 12 weeks.

About Osteoarthritis (OA) of the Knee
OA is the most common joint disease, affecting more than 30 million Americans and accounting 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.
