Flexion Therapeutics Inc Stock: price and insider trades · United States

Flexion Therapeutics Inc. was a U.S.-based biopharmaceutical company focused on musculoskeletal pain, especially osteoarthritis, and it was listed in the U.S. on a major exchange market (NASDAQ/NYSE context). Headquartered in Burlington, Massachusetts, United States, the company built its strategy around local therapies designed to deliver medication directly to the site of pain, with the goal of improving efficacy while reducing systemic exposure. That positioning gave Flexion a clear identity in the non-opioid pain-management segment, where innovation in drug delivery could matter as much as the active ingredient itself.

Flexion’s core commercial asset was ZILRETTA, an extended-release injectable suspension of triamcinolone acetonide for osteoarthritis knee pain. ZILRETTA received FDA approval in 2017 and became the company’s flagship product. Its differentiation came from proprietary microsphere technology intended to provide longer-lasting relief than conventional steroid injections. In investor and company communications, Flexion also discussed a broader research pipeline for musculoskeletal conditions and additional local therapies, but in practice the company remained largely a single-product story before the corporate transaction that ended its independence.
