Tenax Therapeutics Reports Fiscal Year 2020 Results and Provides Business Update

“Now that the merger with PH Precision Medicine is complete, we have clinical development programs in group one and group two Pulmonary Hypertension patients,” stated Anthony DiTonno, Chief Executive Officer of Tenax, “which represent more than 70% of the overall market.”

“Having acquired the oral formulation rights of Levosimendan from our agreement with Orion, we have set up an open label transition study to determine the dose we will take into Phase 3 trials in 2022. The Phase 2 HELP trial still has patients in the open label phase of the trial. We will be bringing those patients back to their clinics and converting them to the oral dosage form. We believe an oral dosage form will be more convenient to patients and provide more consistent blood levels of drug as opposed to weekly IV administration.”

“With respect to the imatinib program, we continue to make good progress on developing a formulation that will address previous GI-related side effects associated with its oral administration. We remain highly enthusiastic that imatinib, when formulated correctly, will show substantial clinical benefit in the pulmonary arterial hypertension (PAH) patient population, with the potential to be the first disease-modifying therapy for this indication. As we finalize our plans, we will provide additional updates.”

Recent Highlights

• On March 2, 2021, Tenax announced the appointment of four new members to its board of directors: June Almenoff, MD, PhD, Michael Davidson, MD, Declan Doogan, MD, and Stuart Rich, MD. Together, these highly accomplished professionals will provide the Board with significant scientific and commercial perspectives that will prove invaluable as we execute on our long-term corporate strategy. Over the next several months, Tenax expects to advance its two leading pipeline assets into late-stage clinical testing, so the expansion of its board to include such expertise from both the medical community and the pharmaceutical industry could not come at a better time for the company and its shareholders.
• On January 19, 2021, Tenax announced the acquisition of PH Precision Med (PHPM), a privately-held clinical stage biotech company focused on developing imatinib for the treatment of pulmonary arterial hypertension (PAH). The FDA has granted Orphan Drug Designation for imatinib for the treatment of PAH, an indication with a high unmet medical need. The acquisition of PHPM immediately expands Tenax’s pipeline to include a second de-risked Phase 3 ready candidate with the potential to be the first disease modifying treatment of PAH.
• On January 15, 2021, Tenax appointed Stuart Rich, MD, co-founder of PHPM, Chief Medical Officer of Tenax Therapeutics. Dr. Rich currently serves as Professor of Medicine at Northwestern University Feinberg School of Medicine, and Director of the Pulmonary Vascular Disease Program at the Bluhm Cardiovascular Institute. He previously served as FDA Cardio-Renal Advisory Committee Member. His many years of experience as an FDA advisory committee member provides Tenax with an extraordinary knowledge of pulmonary hypertension disease mechanisms and modern regulatory strategies. With his appointment, Tenax is well positioned to maximize the clinical potential of imatinib and advance the clinical development of levosimendan for PH-HFpEF, which together have the potential to address significant unmet needs and large market opportunities.

About Levosimendan

Levosimendan is a calcium sensitizer that works through a unique triple 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.
