Tenax Therapeutics, Inc. Expands Board of Directors

“We are thrilled to welcome June, Michael, Declan and Stuart to our Board of Directors,” said Anthony DiTonno, Chief Executive Officer of Tenax Therapeutics. “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, we expect to advance our two leading pipeline assets into late-stage clinical testing, so the expansion of our board to include such expertise from both the medical community and the pharmaceutical industry could not come at a better time for our company and our shareholders.”

The Tenax pipeline includes two de-risked, Phase 3 ready drug candidates: (1) a reformulation of imatinib for the treatment of pulmonary arterial hypertension (WHO Group 1) with the potential to be the first disease modifying treatment for this indication, and (2) an oral formulation of levosimendan for the treatment of pulmonary hypertension (WHO Group 2), recently in-licensed from Orion. Intravenous Levosimendanwas already approved by the EMA in 2002 for treatment of acute heart failure.

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.
