Raised Gross Proceeds of Approximately $100 Million in a Private Placement with Leading Institutional Healthcare Investors

Continuing to Enroll Patients in Phase 3 LEVEL Study with 39 Investigative Sites Initiated

In April, Hosted the KOL Event, "LEVEL Setting," Featuring Four Experts in Heart Failure Discussing the Unmet Medical Need in PH-HFpEF and Potential of Levosimendan to Address Disease

CHAPEL HILL, N.C., Aug. 13, 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 financial results for the second quarter of 2024 and provided a corporate update.

"In the second quarter, Tenax has undergone a significant transformation made possible by successful execution across our strategic priorities," said Chris Giordano, President and Chief Executive Officer of Tenax. "Several patients randomized in our Phase 3 LEVEL trial in Q1 and early Q2 have now completed 12 weeks of therapy and all have continued into the open label extension. We secured important U.S. intellectual property, and attained the global development and commercial rights to levosimendan for the treatment of PH-HFpEF."

"We also conducted the KOL Event, "LEVEL Setting", in April, which featured a panel of globally renowned cardiologists who reviewed the significant unmet medical need in PH-HFpEF and the potential of levosimendan to address this debilitating condition. Finally, we raised gross proceeds of approximately $100 million in a private placement financing, providing Tenax the resources to further advance the levosimendan Phase 3 program, with the ultimate goal of bringing to market the first FDA-approved treatment for the millions of patients who suffer from PH-HFpEF."

Recent Corporate and Clinical Highlights

In August 2024, Tenax announced the closing of a private placement financing that resulted in total gross proceeds to the Company of approximately $100 million, before deducting placement agent fees and other estimated offering expenses.
In April 2024, Tenax announced that the United States Patent and Trademark Office (USPTO) granted the Company a patent, U.S. Patent No. 11,969,424, covering the use of TNX-103 (oral levosimendan), TNX-102 (subcutaneous levosimendan), TNX-101 (IV levosimendan), the active metabolites of levosimendan (OR1896 and OR18955) and various combinations of cardiovascular drugs with levosimendan when used to improve exercise performance in patients with pulmonary hypertension from heart failure with preserved ejection fraction (PH-HFpEF). The ‘424 patent expressly provides IP protection for levosimendan at all therapeutic doses.
In April 2024, Tenax hosted "LEVEL Setting" – a scientific roundtable exploring the rationale for TNX-103 (oral levosimendan) in the treatment of PH-HFpEF. Presentations were made by four globally recognized experts in the field who then answered questions from attendees (LINK TO EVENT):
- Understanding the setting of PH-HFpEF – Sanjiv Shah, M.D. (Northwestern University)
- Mechanism of Action of Levosimendan – Daniel Burkhoff, M.D., Ph.D. (Cardiovascular Research Foundation and Columbia University)
- Review of data from the Phase 2 HELP Study – Barry Borlaug, M.D. (Mayo Clinic)
- Current treatment landscape in PH-HFpEF – Javed Butler, M.D., M.P.H., M.B.A. (Baylor Scott & White)

Second Quarter 2024 Financial Results

Tenax reported cash and cash equivalents of $9.4 million as of June 30, 2024, versus $9.8 million as of December 31, 2023. Following the close of the reporting period, the Company raised gross proceeds of approximately $100 million in a private placement financing, which closed on August 8, 2024, with leading institutional healthcare investors.

Research and Development expenses for the second quarter of 2024 were $2.3 million, compared to $0.2 million for the second quarter of 2023. The $2.1 million increase year-over-year is primarily attributable to increased costs for the ongoing Phase 3 LEVEL study.

General and administrative expenses for the second quarter of 2024 were $1.3 million versus $1.0 million for the second quarter of 2023.

Tenax reported a net loss of $3.6 million or $1.83 per share for the second quarter of 2024, compared to a net loss of $1.1 million or $4.00 per share for the second quarter of 2023.

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 marketing authorization in 60 countries outside the United States for use in hospitalized patients with acutely decompensated heart failure. Results of Tenax's 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's 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).
