What happened?
On August 10, 2026, Tenax issued a press release reporting topline results from its Phase 3 LEVEL clinical trial. The press release stated that TNX-103 "did not meet its primary endpoint of improvement in the 6-minute walk distance versus placebo, or the key secondary endpoint of improvement in Kansas City Cardiomyopathy Questionnaire total symptom score."

What is the Tenax Therapeutics, Inc. lawsuit about?
The Tenax Therapeutics, Inc. securities lawsuit alleges that, between November 13, 2023 and August 7, 2026, defendants made materially false and/or misleading statements and failed to disclose material adverse facts about Tenax Therapeutics, Inc.'s business, operations, and prospects. Specifically, the complaint alleges defendants failed to disclose that: (1) TNX-103 was less effective than Defendants had led investors to believe; (2) accordingly, TNX-103's overall clinical, regulatory, and commercial prospects were overstated; and (3) as a result, defendants' positive statements about Tenax Therapeutics, Inc.'s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.
"The lawsuit against Tenax Therapeutics, Inc. alleges that, among other things, the Company failed to tell investors that TNX-103 was less effective than Defendants had led investors to believe. Tenax Therapeutics, Inc. investors who bought during the class period may be able to pursue their losses, and the December 28, 2026 deadline is where that process begins," said Howard G.
