Bellerophon Receives Orphan Drug Designation

Bellerophon Therapeutics, Inc. recently announced the US FDA has granted Orphan Drug Designation to nitric oxide for the treatment of Idiopathic Pulmonary Fibrosis (IPF).

IPF is a progressive, irreversible and fatal interstitial lung disease characterized by thickening and scarring of the air sacs in the lungs affecting approximately 100,000 people in the US and reducing their life expectancy to between two and five years from diagnosis. IPF patients suffer from severe functional impairment that limits their ability to perform basic daily tasks, resulting in a significant deterioration in their quality of life. Pulsed nitric oxide, delivered via Bellerophon’s patented INOpulse device and delivery algorithm, is the first therapy with the potential to improve a patient’s physical activity levels, cardiac output and oxygen saturation by treating both the ventilation perfusion mismatch driven by the fibrosis, as well as pulmonary hypertension, a common comorbidity in the IPF patient population.

Bellerophon is currently conducting a Phase 2/3 (iNO-PF) study of nitric oxide and its proprietary INOpulse system to treat patients with IPF, as well as other pulmonary fibrotic diseases.

“The receipt of orphan drug designation represents a significant milestone for our INOpulse clinical development program,” said Fabian Tenenbaum, Chief Executive Officer of Bellerophon. “We are encouraged by the Cohort 1 results of our iNO-PF study, which demonstrated that treatment with INOpulse provided clinically and statistically significant improvement in activity levels. We recently completed enrollment in Cohort 2, which is assessing a higher dose, as well as longer treatment duration, and expect to report top-line results before the end of the year. Moreover, we have FDA agreement on our pivotal Phase 3 Cohort, which we anticipate initiating in the first quarter of 2020. IPF is a debilitating life threatening disease and we believe that INOpulse is well-positioned to potentially become a first-in class therapy for this serious unmet medical need.”

The mission of the FDA’s Office of Orphan Products Development (OOPD) is to advance the evaluation and development of products that demonstrate promise for the diagnosis and/or treatment of rare diseases or conditions that affect fewer than 200,000 people in the US. In fulfilling that task, the OOPD evaluates scientific and clinical data submissions from sponsors to identify and designate products as promising for rare diseases and to further advance scientific development of such promising medical products. Orphan drug designation provides the sponsor access to various development incentives, including tax credits for qualified clinical trial expenditures and waivers for certain FDA user fees. Orphan Drug Designation also provides up to seven years of marketing exclusivity if regulatory approval is received.

Bellerophon Therapeutics is a clinical-stage biotherapeutics company focused on developing innovative therapies that address significant unmet medical needs in the treatment of cardiopulmonary diseases. The Company is currently developing multiple product candidates under its INOpulse program, a proprietary pulsatile nitric oxide delivery system.  For more information, visit
