Bellerophon Completes Enrollment in Cohort 2 of Ongoing Phase 2/3 Study of INOpulse® for Treatment of Pulmonary Hypertension Associated with Interstitial Lung Disease

Initiation of Pivotal Cohort 3 Anticipated in Q1 2020

WARREN, N.J., Aug. 01, 2019 (GLOBE NEWSWIRE) -- Bellerophon Therapeutics, Inc. (BLPH) (“Bellerophon” or the “Company”), a clinical-stage biotherapeutics company, today announced that it has completed enrollment for Cohort 2 of its ongoing Phase 2/3 randomized, double-blind, placebo-controlled clinical study (iNO-PF) of INOpulse® for the treatment of Pulmonary Hypertension associated with Interstitial Lung Disease (PH-ILD).

“We have been extremely pleased with the rate of enrollment in Cohort 2, and are thankful for the continued support and enthusiasm from our sites. We look forward to study completion by year-end 2019,” said Fabian Tenenbaum, Chief Executive Officer of Bellerophon. “Top-line data from Cohort 1 showed that INOpulse demonstrated clinically and statistically significant improvement in moderate to vigorous physical activity, or MVPA, as well as other physical activity parameters measured by continuous activity monitoring. Subsequently, the U.S. Food and Drug Administration agreed with Bellerophon’s proposal that MVPA serve as the primary endpoint and that iNO-PF be amended from a Phase 2b study to a Phase 2/3 trial, providing a seamless transition into Cohort 3, which will serve as the pivotal Phase 3 trial. The results from Cohorts 1 and 2 will be used to determine the optimal dose between iNO30 and iNO45 to progress into Cohort 3, which we expect to initiate in the first quarter of 2020. PH-ILD is a debilitating and life threatening disease where patients suffer severe functional impairment that limit their capacity to perform even the most basic daily tasks. The capability of INOpulse to improve MVPA would directly benefit a patient’s ability to function and provides the potential for the first approved therapy in this unmet medical need.”

Cohort 2 of iNO-PF includes 44 subjects randomized 2:1 to either iNO45 (45 mcg/kg IBW/hr) or placebo. Subjects will complete 16 weeks of blinded treatment on iNO45 vs placebo, and then continue onto open-label treatment.

In January 2019, Bellerophon reported top-line data from Cohort 1 of iNO-PF, which included 41 subjects randomized 1:1 to either iNO30 (30 mcg/kg IBW/hr) or placebo for 8 weeks of blinded treatment. Cohort 1 showed clinically meaningful improvements in multiple activity parameters, as well as oxygen saturation:

  • MVPA (walking, stairs, yardwork, etc.) improved by 34% (8% increase on iNO vs. 26% decrease on placebo; p=0.04)
    • 23% of subjects on iNO had a clinically significant improvement in MVPA, compared to 0% of subjects on placebo (placebo corrected difference of 23%)
    • 39% of subjects on iNO had a clinically significant decline in MVPA, compared to 71% of subjects on placebo (placebo corrected difference of 32%)
  • Overall activity improved by 12% (stable on iNO vs. 12% decrease on placebo; p=0.05)
  • Calorie expenditure improved by 12% (6% decrease on iNO vs. 18% decrease on placebo p=0.05)
  • Oxygen saturation improved by 20% (9% improvement on iNO vs. 11% deterioration on placebo)

Cohort 3 of iNO-PF is the pivotal Phase 3 study for approval, with MVPA as the primary endpoint. The study is expected to include approximately 300 subjects randomized 1:1 to active or placebo for 16 weeks of blinded treatment.
