Tenax Therapeutics Reports Second Quarter 2021 Results and Provides Business Update

“We are entering an exciting period for Tenax Therapeutics, with continued progress being made for our two lead clinical programs – imatinib for the treatment of pulmonary arterial hypertension and levosimendan for the treatment of pulmonary hypertension associated with left heart failure,” said Christopher T. Giordano, Chief Executive Officer of Tenax Therapeutics.

“Our imatinib program for PAH remains on track, and we are presently completing the final stages of the formulation work. We believe our new, delayed release, oral formulation of imatinib will confer significant therapeutic advantages over the prior oral formulation, including improved GI tolerability and the potential for disease-modifying clinical activity.”

“With respect to levosimendan, our open label transition study using the oral formulation also remains on track. As a reminder, the purpose of this study is to determine the optimal dosage for levosimendan for our planned Phase 3 trial, which is expected to start in 2022. We believe oral delivery of levosimendan will provide more consistent blood levels compared to weekly IV administration, with the added benefit of administrative convenience to the patient. More than 50% of the subjects in this open label extension study have already transitioned from weekly IV infusion to the daily oral formulation.”

Recent Highlights

• On August 16, 2021, Tenax held a KOL webinar on Levosimendan for pulmonary hypertension with heart failure with preserved ejection fraction (PH-HFpEF). The webinar featured a presentation by Key Opinion Leader (KOL) Daniel Burkhoff, M.D., Ph.D. (Cardiovascular Research Foundation) who discussed the current treatment landscape and unmet medical need in treating patients with pulmonary hypertension with heart failure with preserved ejection fraction (PH-HFpEF) and how levosimendan could become an important new treatment option for this patient population.
• On August 12, 2021, Tenax announced the publication of a new article that identifies a novel mechanism of action behind the improved cardiovascular hemodynamics and exercise tolerance that was reported in the recent Phase 2 HELP Study (Burkhoff et al., JACC Heart Failure 2021; 9:360-70). The new publication, “Changes in Stressed Blood Volume with Levosimendan in Pulmonary Hypertension from Heart Failure with Preserved Ejection Fraction: Insights Regarding Mechanism of Action” appears in the Journal of Cardiac Failure. The article is available online as an “Article In Press.” https://www.onlinejcf.com/article/S1071-9164(21)00215-3/fulltext

The unregistered pre-funded warrants have an exercise price of $0.0001 per share of common stock, are immediately exercisable, and may be exercised at any time until exercised in full. The unregistered warrants have an exercise price of $1.97 per share of common stock, are immediately exercisable, and will expire five and one-half years from the date of issuance. The aggregate gross proceeds to the Company of the offering was approximately $10 million

Financial Results

• Research and development expenses for the second quarter of 2021 were $0.7 million, compared to $1.3 million for the second quarter of 2020.
• General and administrative expenses for the second quarter of 2021 were $1.3 million, compared to $0.9 million for the second quarter of 2020.
• Net loss for the second quarter of 2021 was $1.7 million, or $0.10 per share, compared to a net loss of $2.1 million, or $0.23 per share, for the second quarter of 2020.
• Cash, cash equivalents and marketable securities totaled $2.2 million as of June 30, 2021, compared with $6.7 million as of December 31, 2020. Following the close of the second quarter, Tenax raised $10 million in gross proceeds from an equity offering with a single institutional investor. Including the proceeds from this offering, management expects that current cash, cash equivalents and marketable securities, including the net proceeds from the July 2021 offering, will be sufficient to fund current operations through the second quarter of 2022.

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.
