Tenax Therapeutics Announces Closing of $100 Million Private Placement and Plans to Accelerate the Oral Levosimendan Phase 3 Program

• Funding supports advancement of oral levosimendan (TNX-103) Phase 3 development program, including completion of the ongoing LEVEL Study for the treatment of Pulmonary Hypertension Due to Heart Failure with Preserved Ejection Fraction (PH-HFpEF)

• Proceeds also will fund the initiation of a second Phase 3 study planned for 2025, shortening timeline to NDA submission; the protocol for this study will be submitted to FDA for comment

CHAPEL HILL, N.C., Aug. 12, 2024 (GLOBE NEWSWIRE) -- Tenax Therapeutics, Inc. (“Tenax”) (NASDAQ: TENX), a Phase 3, development-stage pharmaceutical company focused on developing and commercializing products that address cardiovascular and pulmonary diseases with high unmet medical need, announced the closing of a private placement by certain institutional and accredited healthcare investors, raising gross proceeds of approximately $100 million.

The oversubscribed private placement was led by new investor BVF Partners LP, with participation from other new investors, including Venrock Healthcare Capital Partners, Vivo Capital, Janus Henderson Investors, a large investment management firm, Vestal Point Capital, Velan Capital, ADAR1 Capital Management, LLC, Stonepine Capital Management, and Sphera Biotech.

“This transformational financing is a significant commitment by top-tier biotech investors who believe in levosimendan’s potential to impact the lives of patients suffering from PH-HFpEF,” said Chris Giordano, President and Chief Executive Officer of Tenax Therapeutics. “The proceeds position us to accelerate our ongoing Phase 3 development program and shorten the time to NDA submission. We are now funded through completion of the ongoing Phase 3 LEVEL study, including its open label extension. This funding should also enable us to initiate all sites and advance enrollment in a second, global Phase 3 study. The Tenax team looks forward to completing the Phase 3 studies of oral levosimendan in treatment of PH-HFpEF patients, the only therapy shown to produce favorable hemodynamic changes and improve exercise tolerance in these patients.”

The LEVEL study is designed to demonstrate the impact of daily oral levosimendan administration on exercise ability, as measured by the six-minute walk distance (6MWD) test, over a 12-week period. PH-HFpEF is a devastating disease that severely impacts patients’ daily activity levels, and for which no therapies have been approved by the U.S. Food and Drug Administration.

“Participants in the HELP study showed an approximate 10% improvement of 29 meters in their six-minute walk distance over a six-week period, making levosimendan the first drug to show exercise improvement in any patients with HFpEF, with or without PH. In a subsequent open-label study, patients showed further improvement in exercise capacity when transitioned from weekly IV to oral daily therapy,” said Stuart Rich, MD, Chief Medical Officer of Tenax Therapeutics. Several other clinical assessments also demonstrated benefit following the transition to oral therapy, currently being tested in the Phase 3 LEVEL study.

About Levosimendan (TNX-101, TNX-102, TNX-103)

Levosimendan is a unique, potassium ATP channel activator and calcium sensitizer that affects the heart and vascular system through multiple mechanisms of action. Initially discovered and developed by Orion Corporation in Finland, intravenous levosimendan has been granted market authorization in 60 countries outside the United States for use in hospitalized patients with acutely decompensated heart failure. Results of Tenax Therapeutics’ Phase 2 HELP study of levosimendan in patients with pulmonary hypertension (PH) with heart failure with preserved ejection fraction (HFpEF) demonstrated that IV levosimendan produces potent dilation of the central and pulmonary venous circulations which translates into an improvement in exercise capacity, a discovery that is the basis of LEVEL, the Phase 3 investigation of Tenax Therapeutics’ potential groundbreaking therapy. To date, no other drug therapy has improved exercise tolerance in patients with PH associated with HFpEF, “a growing epidemic with high morbidity and mortality and no treatment. The clear unmet need and lethal nature of PH-HFpEF must be met with novel solutions at all levels of therapeutic development” (AHA Scientific Advisory, “A Call to Action,” 2022).
