Tenax Announces Publication Titled “Levosimendan Improves Hemodynamics and Exercise Tolerance in PH-HFpEF: Results of the Randomized Placebo-Controlled HELP Trial ”
Tenax Therapeutics, Inc. (Nasdaq: TENX) has released positive results from its Phase 2 HELP Study, evaluating levosimendan for pulmonary hypertension and heart failure with preserved ejection fraction (PH-HFpEF). The study showed an 84% responder rate in the open-label phase, although levosimendan did not significantly reduce exercise-PCWP compared to placebo. Notably, it improved the six-minute walk distance by 29.3 meters compared to placebo (p=0.033). The publication emphasizes the need for further studies on levosimendan, which demonstrates potential as a treatment for this severe condition.
- 84% responder rate in the open-label phase of the HELP Study.
- Significant improvement in 6-minute walk distance by 29.3 meters compared to placebo (p=0.033).
- First drug to show improved hemodynamics in PH-HFpEF patients.
- Did not significantly reduce primary endpoint of exercise-PCWP (-1.4 mmHg, p=0.65).
Tenax Therapeutics, Inc. (Nasdaq: TENX), a specialty pharmaceutical company focused on identifying and developing therapeutics that address cardio-pulmonary diseases with high unmet medical need, today announced the publication of positive data from the company’s Phase 2 HELP Study that evaluated levosimendan in patients with pulmonary hypertension and heart failure with preserved ejection fraction (PH-HFpEF). The new publication is titled Levosimendan Improves Hemodynamics and Exercise Tolerance in PH-HFpEF: Results of the Placebo-Controlled HELP Trial and was published in the Journal of American College of Cardiology: Heart Failure (https://www.jacc.org/doi/pdf/10.1016/j.jchf.2021.01.015).
The HELP (Hemodynamic Evaluation of Levosimendan in PH-HFpEF) Study was designed as a randomized placebo-controlled trial to evaluate the hemodynamic and clinical effects of weekly levosimendan IV infusions in PH-HFpEF patients. This 6-week study design evaluated invasive cardiovascular hemodynamics as well as secondary clinical endpoints including a 6-minute walk test.
Results reported in the publication include an impressive responder rate of
Dr. Daniel Burkhoff, MD PhD, Director of Heart Failure, Hemodynamics and Mechanical Circulatory Support Research at Cardiovascular Research Foundation led the blinded hemodynamic core lab and analysis for the HELP trial and is the first author on the publication. Dr. Burkhoff stated “The cardiovascular hemodynamic effects seen in this trial following levosimendan administration were impressive, especially in the first 24 hours. The reductions in cardiac filling pressures and associations with improved exercise performance are important early markers of clinical benefit and signify meaningful improvements in the wellbeing of PH-HFpEF patients. Levosimendan has the potential to have a major impact on the treatment of PH-HFpEF."
Dr. Stuart Rich, Chief Medical Officer at Tenax Therapeutics and Principal Investigator of the study stated “PH-HFpEF, which is Group 2 Pulmonary Hypertension, is a progressive and fatal disease with no effective medical treatments. Previous attempts to identify an effective treatment from clinical trials using approved pulmonary vasodilators have all failed. This is the first multi-center, randomized, placebo-controlled trial in PH-HFpEF patients to report a statistically significant improvement in 6-minute walk distance. Levosimendan has unique pulmonary vascular and cardiovascular properties which we identified as central to its clinical efficacy. The fact that
About Tenax Therapeutics

About Levosimendan
Levosimendan is a calcium sensitizer and K-ATP Channel activator that works through a unique mechanism of action. It initially was developed for intravenous use in hospitalized patients with acutely decompensated heart failure. It was discovered and developed by Orion Pharma, Orion Corporation of Espoo Finland, and is currently approved in over 60 countries for this indication and not available in the United States. Tenax Therapeutics acquired North American rights to develop and commercialize levosimendan from Phyxius Pharma, Inc.
About Imatinib
Imatinib is an antiproliferative agent developed to target the BCR-ABL tyrosine kinase in patients with chronic myeloid leukemia. The inhibitory effects of imatinib on PDGF receptors and c-KIT suggested that it may be efficacious in PAH. Imatinib reversed experimentally induced pulmonary hypertension and has pulmonary vasodilatory effects in animal models and proapoptotic effects on pulmonary artery smooth muscle cells from patients with idiopathic PAH. In a phase 3 clinical trial imatinib produced significant improvements in exercise capacity, but a high rate of dropouts attributed largely to gastric intolerance prevented regulatory approval.
