Bellerophon Therapeutics Announces Enrollment Exceeds 100 Patients in Phase III INOvation-1 Study Evaluating INOpulse for Treatment of Pulmonary Arterial Hypertension

WARREN, N.J., Jan. 29, 2018 (GLOBE NEWSWIRE) -- Bellerophon Therapeutics (Nasdaq:BLPH), a clinical-stage biotherapeutics company, today announced that enrollment in its Phase 3 INOvation-1 study evaluating INOpulse® in patients with pulmonary arterial hypertension (PAH) now exceeds 100 patients, representing more than half of the anticipated enrollment.  As previously agreed with the U.S.Food and Drug Administration (FDA), an interim analysis of this trial will be performed by the Data Monitoring Committee when half of the subjects complete the 16-week blinded treatment phase.  The interim analysis will determine if the study should be stopped early for efficacy or futility, continued as planned, or if the trial size should be increased.  The Company anticipates the readout of the interim analysis in mid-2018, and the availability of top-line data from the full study toward the end of 2018.

“I am excited to be participating in the INOvation-1 study, and pleased to see strong momentum in recruitment,” said Dr. Marion Delcroix, Professor of Medicine and of Respiratory Physiology at the KU Leuven in Belgium, an investigator and member of the PAH Steering Committee.  “PAH remains an underserved disease with poor quality of life and no cure.  INOpulse’s unique mechanism of action delivers a precise dose of pulsatile nitric oxide, a potent and well validated vasodilator, and has the potential to become an important new therapy in the management of PAH patients.”

“We are pleased with the progress achieved to date in this Phase 3 study,” said Fabian Tenenbaum, President and Chief Executive Officer of Bellerophon.  “We believe this speaks to the desire for PAH patients to seek more effective and tolerable treatment alternatives, as well as the enthusiasm and dedication of our investigators and clinical development team.  We look forward to the interim analysis in mid-2018, and the continued advancement of our INOvation-1 trial over the remainder of the year.”

The INOpulse PAH Phase 3 program consists of two studies, the INOvation-1 study, and a confirmatory randomized withdrawal study with approximately 40 patients who will cross over from the INOvation-1 study. 

  • The INOvation-1 study is evaluating the safety and efficacy of the INOpulse delivery system for the treatment of patients with PAH on long-term oxygen treatment (LTOT).  The INOpulse delivery system utilizes a proprietary technology to deliver pulsatile inhaled nitric oxide (iNO), allowing for use in a portable chronic setting.  The primary endpoint of the study is Six Minute Walk Distance (6MWD), with Time to Clinical Worsening as a secondary endpoint.
  • The INOvation-1 trial includes an interim analysis after approximately half the patients have completed the 16-week blinded phase on either iNO at a dose of 75 mcg/kg IBW/hr (iNO75) or placebo.  The interim analysis will be conducted by the independent Data Monitoring Committee, which will provide the Company with one of four predetermined decisions, including allowing the trial to be stopped early if efficacy has been demonstrated, continuing the trial to the planned size, increasing the trial size to reach a threshold of conditional powering, or halting the trial for futility.

As agreed with the FDA, the INOvation-1 and withdrawal studies can serve as the two adequate and well-controlled studies required to support a New Drug Application filing for INOpulse in PAH subjects on LTOT.

About Pulmonary Arterial Hypertension
Pulmonary arterial hypertension is one form of a broader condition known as pulmonary hypertension, which means high blood pressure in the lungs.  PAH occurs when the very small arteries throughout the lungs narrow in diameter, which increases the resistance to blood flow through the lungs. Over time, the increased blood pressure can damage the heart.  A number of diseases and conditions can cause PAH, and symptoms are similar to the symptoms often seen in more common diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and heart failure.

About Bellerophon
Bellerophon Therapeutics is a clinical-stage biotherapeutics company focused on developing innovative therapies at the intersection of drugs and devices that address significant unmet medical needs in the treatment of cardiopulmonary diseases. The Company is currently developing three product candidates under its INOpulse program, a proprietary pulsatile nitric oxide delivery system. The first is for the treatment of PAH, for which the Company has commenced Phase 3 clinical trials. The second is for the treatment of pulmonary hypertension associated with chronic obstructive pulmonary disease (PH-COPD) and the third candidate is for the treatment of pulmonary hypertension associated with Interstitial Lung Disease (PH-ILD), both of which are in Phase 2 development.  For more information, please visit
