Bellerophon Provides Clinical Program Update and Reports Second Quarter 2021 Financial Results

​

WARREN, N.J., August 5, 2021 – Bellerophon Therapeutics, Inc. (Nasdaq: BLPH) (“Bellerophon” or the “Company”), a clinical-stage biotherapeutics company focused on developing treatments for cardiopulmonary diseases, today provided a clinical program update and reported financial results for the second quarter ended June 30, 2021.

​

“We continue to progress our INOpulse® inhaled nitric oxide therapy in multiple areas of significant unmet need,” said Fabian Tenenbaum, Chief Executive Officer of Bellerophon. “Our ongoing pivotal Phase 3 REBUILD study for fibrotic interstitial lung disease, or fILD, patients at risk of associated pulmonary hypertension is progressing well and continuing to enroll. In addition, we expect top-line results from our Phase 2 dose escalation study of INOpulse in sarcoidosis, or PH-Sarc, later this year. With $34.3 million in cash and cash equivalents, we believe that we are well-positioned financially to continue executing on our promising late-stage clinical development programs.”

Clinical Program Highlights:

​

fILD

​

The Phase 3 program builds on positive top-line results from the Company’s previously reported Phase 2 studies for INOpulse for the treatment of fILD. Acute treatment with INOpulse showed benefit in multiple cardiopulmonary parameters, including pulmonary vascular resistance, which improved by 21%, and mean pulmonary arterial pressure, which improved by 12%. Chronic treatment with INOpulse at a dose of iNO45 assessed over four months showed an average improvement in MVPA of 20% as compared to placebo. The improvements in MVPA were supported by benefits in overall activity, as well as two patient reported questionnaires, the University of California, San Diego Shortness of Breath Questionnaire and the St. George’s Respiratory Questionnaire.
