Bellerophon Reports Positive Top-Line Data from Phase 2 Acute Dose Escalation Study of INOpulse® for Treatment of Pulmonary Hypertension Associated with Sarcoidosis

December 17, 2021 GMT

Phase 2 results provide clinically meaningful reduction in pulmonary vascular resistance; Company intends to design multi-dose Phase 2b trial

Treatment was safe and well-tolerated, with no treatment-emergent adverse events observed during the acute hemodynamic dose escalation phase of the study

WARREN, N.J., Dec. 17, 2021 (GLOBE NEWSWIRE) -- Bellerophon Therapeutics, Inc. (Nasdaq: BLPH) (“Bellerophon” or the “Company”), a clinical-stage biotherapeutics company focused on developing treatments for cardiopulmonary diseases, today announced positive top-line data from a recently completed Phase 2 dose escalation study (PULSE-PHPF-002) evaluating the acute hemodynamic benefit of INOpulse® via right heart catheterization for the treatment of pulmonary hypertension associated with sarcoidosis (PH-Sarc).

The Phase 2 trial was designed as a proof of concept study to determine if iNO could demonstrate hemodynamic benefit in PH-Sarc. Key results included:

  • All 8 subjects demonstrated decreases in mean pulmonary arterial pressure (mPAP) and pulmonary vascular resistance (PVR) across the doses of INOpulse utilized in the study.
  • The dose of iNO45 (45 mcg/kg IBW/hr) resulted in a median drop of 20% (-54% to +22%) in PVR, compared to a median baseline PVR of 329 dyne/cm.sec-5; a reduction of 20% or more in PVR is generally considered to be clinically meaningful.
    • Increasing to the highest dose, iNO125 (125 mcg/kg IBW/hr), demonstrated further improvement in PVR, with a median drop of 29% (-43% to -5%), achieving statistical significance from baseline (p=0.02) and from the preceding lower dose of iNO75 (75 mcg/kg IBW/hr) (p=0.02). During the study, 7 out of 8 patients escalated to the highest dose, iNO125.
  • Along with the improvements in PVR, mPAP decreased by a median of 6-10% across the doses of iNO30 to iNO125, compared to a median baseline mPAP of 37.2 mmHg.
  • No treatment-emergent adverse events (TEAEs) or serious adverse events (TESAEs) occurred during the acute hemodynamic dose escalation phase of the study.

“Sarcoidosis associated pulmonary hypertension has a median survival of approximately five years after development of the pulmonary hypertension. I am encouraged by the positive changes observed in multiple hemodynamic parameters in patients with sarcoidosis associated pulmonary hypertension being treated with long-term oxygen therapy and then acutely treated with INOpulse,” said Robert Baughman, M.D., Professor of Medicine at the University of Cincinnati and one of the Principal Investigators for Study PULSE-PHPF-002. “These clinically meaningful improvements in PVR started at the iNO45 dose and were well tolerated with no clinically relevant deterioration in pulmonary capillary wedge pressure or other hemodynamic parameters, even at the higher iNO doses. The results from this cohort of patients support further evaluation of the potential of iNO to treat PH-Sarc patients who are in urgent need of safe and effective therapies.”

“We are pleased with the positive top-line data from this proof-of-concept study,” said Naseem Amin, M.D., Chairman of Bellerophon’s Board of Directors. “Based on these results, Bellerophon is working with its steering committee, which is comprised of multiple pulmonary disease experts, to assess next steps for this program, including the design of a multi-dose Phase 2b study to assess the chronic benefit of iNO in PH-Sarc patients. We look forward to continuing our development program in PH-Sarc, a rare disease with significant morbidity and mortality for which there are no approved treatment options. Bellerophon will continue to provide additional updates on our clinical activities in the coming year, including our ongoing Phase 3 program in fibrotic interstitial lung disease, the REBUILD study.”
