TENX is trading near its 52-week low of $5.78 (65% below the low).

Summary

Tenax Therapeutics' Phase 3 LEVEL trial of TNX-103 for pulmonary hypertension missed its primary endpoint (six-minute walk distance) and key secondary endpoint (KCCQ symptom score). Shares crashed 85% in premarket trading to $2.07, wiping out most of the company's market cap. The company highlighted a potential benefit in a subgroup with greater disease burden and plans to request an FDA Type C meeting to discuss revisions to the registrational program. This follows the July 31 10-Q showing a $17.8M quarterly loss and $118M in cash, with runway to Q2 2028. The trial failure puts the entire oral levosimendan program at risk and raises questions about the company's ability to continue as a going concern if the FDA path is not viable.

At the time of this announcement, TENX was trading at $2.03 on NASDAQ in the Life Sciences sector, with a market capitalization of approximately $503M. The 52-week trading range was $5.78 to $19.40. This news item was assessed with negative market sentiment and an importance score of 10 out of 10. Source: Dow Jones Newswires.
