Tenax Therapeutics faces class action lawsuit over overstated drug efficacy and 90% stock drop.

Tenax Therapeutics is facing a class action lawsuit alleging it misled investors about the effectiveness of its drug TNX-103 for pulmonary hypertension. The lawsuit claims the company overstated the drug's clinical and commercial prospects, leading to a nearly 90% drop in its stock price after disappointing Phase 3 trial results were announced in August 2026. Investors who bought Tenax securities between November 2023 and August 2026 can seek to become lead plaintiff in the case by December 28, 2026. The lawsuit is filed under the Securities Exchange Act of 1934 and is being handled by Robbins Geller Rudman & Dowd LLP.
