Breaking Pharma Stock News: Tenax Therapeutics (Nasdaq: $TENX) Reports Positive Results from Phase 2 Trial of Levosimendan in Patients with Pulmonary Hypertension and Heart Failure with Preserved Ejection Fraction (PH-HFpEF)
- Demonstrated a significant reduction in right atrial and pulmonary capillary wedge pressures
- Demonstrated a significant improvement with 6-minute walk distance
- No significant safety issues.
June 2, 2020 (Investorideas.com Newswire) 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 announced positive Phase 2 results for levosimendan for the treatment of patients with pulmonary hypertension and heart failure with preserved ejection fraction (PH-HFpEF). In this 37 patient study, the primary efficacy analysis, pulmonary capillary wedge pressure (PCWP) during exercise did not demonstrate a statistically significant reduction from baseline. Levosimendan did demonstrate a statistically significant reduction in PCWP compared to baseline (p=<0.0017) and placebo (p=<0.0475)when the measurements at rest, with legs up and on exercise were combined. Levosimendan also demonstrated a statistically significant improvement in 6-minute walk distance (6MWD) as compared to placebo (p=0.0329).
Dr. Stuart Rich, Professor of Medicine at the Bluhm Cardiovascular Institute at Northwestern University commented "Levosimendan is the first drug to ever show a favorable mechanism of action with biventricular effects in patients with PH-HFpEF. The consistency of the hemodynamic data and improvement in 6-minute walk demonstrates that levosimendan has great promise as a treatment for PH-HFpEF which has a serious unmet need. The favorable safety profile, especially the absence of any proarrhythmic effects, supports the further development with a phase 3 trial."
Hemodynamic measurements were made at rest (supine), after leg raise on a supine bicycle (a test of rapid increase in ventricular filling) and during exercise (25 watts for 3 minutes or until the patient tired). Levosimendan demonstrated a statistically significant reduction in PCWP compared to baseline (p=<0.0017) and placebo (p=<0.0475) when the measurements at rest, with legs up and on exercise were combined. While there was no significant change in PCWP during exercise, patients receiving levosimendan had reductions from baseline at Week 6 in PCWP, pulmonary artery pressure (PAP), and right atrial pressure (RAP) that were significant when patients were "at rest" and/or with their "legs raised" (p<0.05).
Clinical Results (6 Minute Walk Distance)
The clinical efficacy was confirmed by a statistically significant improvement in 6-minute walk distance of 29 meters. (p=0.0329). The 6-minute walk distance was a secondary endpoint in the trial and is a validated and accepted endpoint used in many pulmonary hypertension registration trials. Levosimendan was given in once-weekly home infusions for 6 weeks.
The incidence of AEs or SAEs between the control and treated groups were similar. In addition, there were no arrhythmias observed, atrial or ventricular, when comparing baseline electrocardiographic monitoring with 72-hour monitoring after 5 weeks of treatment. The company plans to present the full study results at future medical meetings and will submit a full manuscript of the trial results to a peer-reviewed journal.
"The positive outcome of this Phase 2 trial represents a major milestone for Tenax and our development of levosimendan for the treatment of patients suffering from this debilitating illness," stated Anthony DiTonno, Chief Executive Officer of Tenax. "It is particularly exciting to report these positive results that support our confidence that levosimendan's unique pharmacologic profile and mechanism of action may be ideally suited to treat PH-HFpEF. We believe these results support a Phase 3 trial that will translate into the first approved therapy to treat these patients."

About Phase 2 HELP Trial
The HELP Trial - Hemodynamic Evaluation of Levosimendan in PH-HFpEF is a multi-center, double-blind, placebo-controlled Phase 2 clinical trial designed to evaluate levosimendan in 36 patients with pulmonary hypertension and heart failure with preserved ejection fraction (PH-HFpEF). 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. The primary endpoint of the HELP Trial is based on change in PCWP vs baseline compared to placebo.
