Inhaled Treatment for Bronchopulmonary Dysplasia
August 7, 2023 updated by: Thomas Michael Raffay, MD, University Hospitals Cleveland Medical Center
Pilot Study of an Inhaled Treatment for Bronchopulmonary Dysplasia
The primary objective of this study is to provide expanded access of S-nitrosylation therapy for the treatment of bronchopulmonary dysplasia
Study Overview
Detailed Description
Open label study with 20 participants, open-label, with block dose escalation of 3 subjects/dose (0.5 mL/kg of 0.25 mM, 0.5 mM, or 1 mM).
A minimum of seven days of surveillance will separate dosing blocks.
An additional 11 subjects will be enrolled at the maximum 1 mM block (5x10-7 moles/kg).
The primary outcomes are safety during 30 minutes of inhalation, and for 4 hours after inhalation, as measured by occurrence of adverse events related to the treatment + time period [during administration and tracked for next 7 days].

- Patients that are ventilated with a device not certified for blending of aerosolized solutions into the ventilator circuit
- Physician of record opposed to enrolling the patient due to perceived safety concerns; or any condition that does not allow the protocol to be followed safely
