Tenax Therapeutics Reports First Quarter 2021 Results and Provides Business Update

“Having completed the merger with PHPrecisionMed Inc., we now have product 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.

“We have begun the open label transition study using the oral formulation of Levosimendan, which was recently acquired from our agreement with Orion. The purpose of this study is to determine the dose we will take into Phase 3 trials in 2022. Study participants who enrolled in our open label Phase 2 HELP trial are being brought back into their clinics and converted to the oral dosage form. We believe oral delivery will be more convenient for patients and provide more consistent blood levels of Levosimendan compared to weekly IV administration.

“With respect to the imatinib program, we are in the final stages of formulation development. As a reminder, this new formulation is expected to address the 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. The new formulation will be tested in a Phase 1 study, which we anticipate completing in the second half of this year.”

Recent Highlights

• On April 9, 2021, Tenax 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).
• On January 19, 2021, Tenax announced the acquisition of PHPrecisionMed Inc. (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.

Financial Results

• Research and development expenses for the first quarter of 2021 were $22.4 million, compared to $1.3 million for the first quarter of 2020. The increase in research and development expense in the current period is due primarily to the recognition of approximately $21.8 million of in-process research and development (IPR&D) expense attributed to the acquisition of PHPM in January 2021.

• General and administrative expenses for the first quarter of 2021 were $1.4 million, compared to $1.3 million for the first quarter of 2020.

• Net loss for the first quarter of 2021 was $23.7 million, or $1.64 per share, compared to a net loss of $2.7 million, or $0.38 per share, for the first quarter of 2020.

• Cash, cash equivalents and marketable securities totaled $4.0 million as of March 31, 2021, compared with $6.7 million as of December 31, 2020.

• Management expects that current cash, cash equivalents and marketable securities will be sufficient to fund current operations through the third quarter of 2021.

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.
