|Bellerophon Therapeutics Announces Positive Data From Interim Analysis of Phase 2 Long-Term Extension Study of INOpulse(R) for Treatment of Pulmonary Arterial Hypertension|
Conference Call/Webcast to Be Held
Interim Data Reinforces Earlier Phase 2 Data and Indicates Sustainability of Benefits for PAH Patients
FDA Issues a Special Protocol Assessment (SPA) for Phase 3 PAH Program
Data From Interim Analysis
Following 16 weeks of blinded therapy in Part 1 of the trial, in Part 2 of the trial 65 patients were randomized to receive INOpulse doses of either 25 or 75 mcg/kg ideal body weight per hour (iNO 25 or iNO 75). The interim analysis was performed after patients had completed between 8 and 12 months of INOpulse treatment, and data from the interim analysis was compared to baseline measurements taken at the beginning of Part 1 of the trial. All patients in the trial were on at least one approved PAH therapy, and several were on two or three PAH therapies.
The interim analysis showed the following:
A total of 14 LTOT patients in the iNO 75 dose treatment arm underwent right heart catheterizations, which showed a mean improvement in pulmonary vascular resistance (PVR) -- the primary endpoint in Part 1 of the Phase 2 trial -- of 87.3 dynes.sec.cm-5. LTOT patients randomized from placebo to iNO 75 in Part 2 did particularly well.
Moreover, LTOT patients in the iNO 75 dose treatment arm also showed an overall improvement in WHO Functional Classification.
The Company also reported that LTOT patients in the iNO 25 dose treatment arm who remained on therapy for 8-12 months in the long-term extension study showed an improvement in 6MWD and PVR though less significant than LTOT patients in iNO 75 dose treatment arm. Patients who were not on LTOT in both treatment arms had mixed results over the same period.
Phase 3 Development Program
The key elements of the planned U.S. and EU Phase 3 development program are:
The Phase 3 trials will utilize the second-generation INOpulse Mark 2 device, which is considerably smaller and lighter (approximately 2.5 lbs.) than the original INOpulse device used in the Phase 2 study (approximately 7.5 lbs.). In addition to the significant reduction in size and weight, the INOpulse Mark 2 device also has an improved user interface and better breath detection technology, made possible by the Company's proprietary tri-lumen cannula.

About Pulmonary Arterial Hypertension
Pulmonary Arterial Hypertension (PAH) is a rare, chronic and currently incurable disease that causes the walls of the arteries of the lungs to tighten and stiffen. Estimates suggest that there are about 15,000 patients diagnosed with PAH in
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 and cardiac diseases. The Company is currently developing two product candidates under its INOpulse® program, a proprietary pulsatile nitric oxide delivery device. The first is for the treatment of pulmonary arterial hypertension (PAH), for which the Company intends to commence Phase 3 clinical trials in 2015, and the other for the treatment of pulmonary hypertension associated with chronic obstructive pulmonary disease (PH-COPD), which is in Phase 2 development. The Company's plans also call for the completion of further work on the use of INOpulse to treat Pulmonary Hypertension associated with COPD and Idiopathic Pulmonary Fibrosis during 2016. Additionally, management is reviewing alternative paths forward for its Bioabsorbable Cardiac Matrix program. For more information, please visit www.bellerophon.com.
