fILD is a severe progressive disease that causes lung tissue scarring characterized by debilitating functional impairment, poor quality of life and limited life expectancy in patients.

REBUILD is a phase III double-blind, placebo-controlled study being conducted to evaluate the safety and efficacy of INOpulse, a pulsed inhaled nitric oxide therapy, at a dose of 45 mcg/kg ideal body weight, in fILD patients versus placebo. The study’s primary endpoint was decided per an FDA consultation and was fixed on observing the change in Moderate to Vigorous Physical Activity (MVPA) in patients.

The REBUILD study was based on the positive data from Bellerophon’s phase II study demonstrating the safety and efficacy of INOpulse in improving the MVPA, multiple quality of life measures and key hemodynamic parameters.

The company previously intended to enroll 300 patients in the study for a 16-week blinded treatment period. However, the company has now decided to reduce the study size. The study’s independent Data Monitoring Committee (DMC) also supported the company’s decision to reduce its study size from 300 to 140 subjects. The decision was made following the evaluation of baseline MVPA characteristics and the safety data of the randomized subjects in the ongoing study.

The study’s primary objective, which is to maintain a power of more than 90% of MVPA based on the effect size observed in the phase II study of the candidate, remains unchanged.
With the reduction in the study size, Bellerophon expects to complete the enrollment in the phase III study by the first quarter of 2023. It also anticipates that the study’s top-line data will be made available by the third quarter of 2023.

Investors must note that apart from being evaluated in fILD, including pulmonary hypertension (“PH”) associated with idiopathic pulmonary fibrosis (“PH-IPF”) and other pulmonary fibrosing diseases, INOpulse is being evaluated for treating PH associated with sarcoidosis (“PH-Sarc”) and PH associated with chronic obstructive pulmonary disease (“PH-COPD”).  

In March 2020, the FDA also granted INOpulse an emergency expanded access (EA) to be a supportive treatment option for COVID-19 patients.
