Tonix Pharmaceuticals Gets FDA Nod to Advance Fibromyalgia Treatment

Shares in biopharmaceutical company, Tonix Pharmaceuticals (Nasdaq: TNXP), climbed on Thursday morning after the company announced that it had successfully completed a positive pre-NDA Chemistry, Manufacturing, and Controls (CMC) meeting with the FDA. Based on formal written feedback, Tonix believes it is aligned with the FDA on key topics, including proposed drug substance and drug product commercial specifications, shelf life assignment, manufacturing and commercial drug packaging.

Tonix remains on track to submit its NDA for Tonmya™, centrally acting, non-opioid, non-addictive, bedtime medication for the management of fibromyalgia to the FDA in the second half of 2024.

Commenting on the news, Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals, said “We remain encouraged and excited about the prospect of bringing the first new treatment to market for fibromyalgia patients in over a decade, and this encouraging meeting with the FDA is an important milestone as we head into the final stages of completion of the NDA package.

“During the pre-NDA CMC meeting, the FDA affirmed alignment with Tonix on CMC content and commercial strategy for Tonmya, and we are very appreciative of the FDA’s guidance as we prepare for our NDA submission. We are currently actively preparing a dual manufacturing launch strategy with global contract development and manufacturing organization (CDMO) Almac Pharma Services and another CDMO.”

Fibromyalgia is a chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system. It affects an estimated 6 million to 12 million adults in the US.
