Tenax Therapeutics Provides Update on Phase 2 Pulmonary Hypertension Clinical Trial

January 13, 2020 GMT

MORRISVILLE, N.C.--(BUSINESS WIRE)--Jan 13, 2020--

Tenax Therapeutics, Inc. (Nasdaq: TENX), a specialty pharmaceutical company focused on identifying, developing and commercializing products that address cardiovascular and pulmonary diseases with high unmet medical need, today provided an update on its on-going clinical trial of levosimendan.

Enrollment Update

Tenax is conducting a multi-center, double-blind, placebo-controlled Phase 2 trial designed to evaluate levosimendan in patients with pulmonary hypertension and heart failure with preserved ejection fraction (PH-HFpEF). The study is also known as the HELP Trial (Hemodynamic Evaluation of Levosimendan in Patients with PH-HFpEF). The Company has activated all 16 sites which it believes will be sufficient to fully enroll the trial. 24 patients, up from 15 at the end of October, are currently enrolled, out of the targeted 36 patients. Given the current pace of patient enrollment, we expect full enrollment in the first quarter of 2020 with top-line data in the first half of 2020.

Initial Response

The trial has a predefined response criterion that patients must meet following a 24-hour open-label infusion of levosimendan before they can be randomized to the 6-week double-blind phase of the trial. The criterion for randomization is a reduction in PCWP during supine exercise of ≥ 4mmHg following the open-label infusion when compared with each patient’s baseline exercise PCWP. 24 of 28 patients, approximately 86%, achieved this predefined responder criterion.

Invasive exercise hemodynamic measurements from 22 enrolled patients showed statistically significant improvements during the open-label lead-in phase when compared to baseline, including an average reduction of 7.6 mmHg PCWP, an average reduction in pulmonary arterial pressure (mPAP) of 4.9mmHg, an average reduction in right atrial pressure (RAP) of 5.2 mmHg, and an average increase in cardiac output (CO) of 0.8 liters/min. All of these open-label lead-in phase hemodynamic improvements achieved statistical significance (P≤0.01, paired t-Test)

Adverse Events

There have been no drug-related serious adverse events, and no patients have withdrawn from the study. All of the patients who have completed the 6-week double-blind phase of the trial have elected to enroll in the open-label extension study.

“We are pleased that enrollment rates have been consistently increasing and initial responses continue to exceed our expectations,” said Tony DiTonno, CEO of Tenax Therapeutics. “We anticipate completing this trial in the months to come and quickly moving forward to the next phase of our development efforts to make levosimendan available to those patients suffering from this debilitating disease.”
