Bellerophon Therapeuetics (NASDAQ:BLPH) has announced it and the US Food and Drug Administration (FDA) have agreed on a regulatory approval pathway for INOpulse for patients with hypertension related to interstitial lung disease.
As quoted in the press release:
In January 2019, the Company reported positive results from Cohort 1 of its ongoing Phase 2b randomized, double-blind, placebo-controlled clinical study (iNO-PF) of INOpulse for the treatment of PH-ILD. Subjects on active treatment demonstrated a statistically significant improvement of 34% in moderate to vigorous physical activity (MVPA) as compared to subjects on placebo, as well as improvements in overall activity, oxygen saturation and additional functional measures. Based on these data and INOpulse’s safety profile, the FDA agreed with Bellerophon on the use of MVPA as the primary endpoint in the pivotal Phase 3 study, as measured by a medical wearable continuous activity monitor (actigraphy). In addition, the Agency agreed with the Company’s proposal that the Phase 2b study be amended to a Phase 2/3 trial. This agreement allows a seamless transition into Cohort 3 of iNO-PF, which will serve as the pivotal Phase 3 trial.
“Reaching this critical agreement with the FDA for INOpulse in PH-ILD represents a significant milestone for Bellerophon as it confirms the validity of MVPA as a clinically meaningful endpoint, enables us to build upon the robust data generated to date from iNO-PF and substantially shortens the regulatory pathway for our therapy in a disease with a serious unmet need,” said Fabian Tenenbaum, Chief Executive Officer of Bellerophon. “We appreciate the FDA’s support and their agreement on both the primary endpoint and the seamless pivotal Phase 2/3 design, creating the opportunity for INOpulse to become the first approved therapy in PH-ILD. We expect to complete Cohort 2 and initiate the pivotal Phase 3 trial in the second half of this year.”
“Compared to surrogate endpoints, such as six-minute walk distance or patient reported outcomes, change in MVPA provides a direct and continuous measure of physical activity in PH-ILD patients, who have limited ability to perform even the most basic daily tasks,” said Steven D. Nathan, M.D., F.C.C.P., Medical Director of the Advanced Lung Disease and Lung Transplant Program at Inova Fairfax Hospital and Chair of Bellerophon’s Steering Committee. “INOpulse is a selective vasodilator that can improve both cardiopulmonary circulation and oxygenation, increasing the ability to perform physical activities. The improvements in MVPA seen to date in iNO-PF support INOpulse’s potential to address this unmet medical need. I am excited by the acceleration of this program into Phase 3 and look forward to the further evaluation of this promising therapy in the clinic.”
