Bellerophon Provides Update on INOpulse® Phase 2b Clinical Program for Treatment of Pulmonary Hypertension Associated with Interstitial Lung Disease
Enrollment of the Planned 40 Subjects Completed, with Top-line Data Expected in January 2019

WARREN, N.J., Oct. 09, 2018 (GLOBE NEWSWIRE) -- Bellerophon Therapeutics, Inc. (Nasdaq: BLPH) (“Bellerophon” or the “Company”), a clinical-stage biotherapeutics company, today provided an update on the Company’s ongoing Phase 2b randomized, double-blind, placebo-controlled clinical study (iNO-PF) evaluating INOpulse® in patients with Pulmonary Hypertension associated with Interstitial Lung Disease (PH-ILD), as well as updated interim results from the Pulmonary Arterial Hypertension (PAH) Phase 3 trial, INOvation-1. 

Bellerophon has completed enrollment of the planned 40 subjects in the iNO-PF trial, with top-line results for this cohort expected in January 2019. These subjects are randomized (1:1) to iNO 30 (30 mcg/kg IBW/hr) vs. placebo, with a one-week run-in period, followed by an eight-week double-blinded treatment period. Following completion of the blinded treatment period, subjects are offered open-label access. The study is evaluating multiple endpoints, including change in six-minute walk distance (6MWD), oxygen saturation, right ventricular function, activity monitoring, patient reported outcomes, as well as several composite endpoints.

In order to support a potential registration package, the Company will expand the iNO-PF study to assess higher doses of iNO and duration of treatment through the addition of two further cohorts. Cohort 2 will include approximately 20 subjects randomized (2:1) to receive either iNO 45 or placebo. Cohort 3 will include approximately 20 subjects randomized (2:1) to receive either iNO 75 or placebo. In addition to evaluating higher doses, cohorts 2 and 3 will increase the blinded treatment period from 8 weeks to 16 weeks. Enrollment in these additional cohorts is expected to begin later this year, with top-line data anticipated in 2019. In addition to the further cohorts, the study is also being modified to allow dose escalation during the open-label period.

“We are pleased with the enthusiasm for our iNO-PF Phase 2b study from investigators and the strong recruitment observed throughout the study. The completion of enrollment in cohort 1 represents an important milestone for our INOpulse clinical development program and we look forward to the availability of these results early next year,” said Fabian Tenenbaum, Chief Executive Officer of Bellerophon. “The expansion of the study to include two additional cohorts will allow us to assess higher doses of iNO with longer duration of treatment. PH-ILD is a significant unmet medical need, with approximately 200,000 patients in the U.S. suffering from this disease that has a mean survival of only two years from diagnosis. There are no approved therapies to treat PH in these patients as the underlying lung disease results in systemic vasodilators causing ventilation-perfusion mismatch and hypoxemia. INOpulse’s unique targeted vasodilation provides the potential for it to be the first approved therapy for patients with PH-ILD.”

Importantly, the interim results from INOvation-1, evaluating INOpulse for the treatment of PAH, verified the INOpulse mechanism of action and support its potential in treating PH-ILD patients. Specifically, following 16 weeks of blinded therapy, subjects on iNO demonstrated clinically meaningful improvement consistent with currently marketed PAH drugs in the following key areas:

  • Pulmonary vascular resistance (PVR) improved by 75 dyne/sec/cm as compared to placebo, which worsened by 111 dyne/sec/cm
  • Cardiac output (CO) improved by 0.5 L/min as compared to placebo, which worsened by 0.2 L/min
  • NT-ProBNP, a peptide biomarker for right ventricular failure, improved by 48 pmol/L compared to placebo, which worsened by 20 pmol/L 
  • Clinically meaningful decline in 6MWD (>15%) was twice as high in the placebo arm as compared to INOpulse
  • 6MWD improved 41 meters (mono PAH therapy) and 25 meters (excluding prostanoids)

“The collective results of INOvation-1 supports the vasodilatory performance of iNO, as well as its clinical benefits in improving hemodynamics, reducing right ventricular failure and preventing decline in 6MWD. In addition, subjects that were not on prostanoids or multiple background therapies showed improvement in 6MWD that is consistent with currently marketed PAH therapies,” continued Mr. Tenenbaum. “These results support the potential benefit that INOpulse can provide for PH-ILD patients, where there are no approved PH therapies and patients are not on any background PAH medications.”
