About

The purpose of this study is to evaluate safety, tolerability and efficacy of BZ371B in intubated patients with severe Acute Respiratory Distress Syndrome.

Full description

Acute respiratory distress syndrome (ARDS) is a severe medical condition that is triggered by an alveolar capillary membrane damage resulted from several causes. Among these causes, respiratory viral infections such as SARS-CoV-2 can be responsible for the development of the disease. ARDS presents a high mortality rate, which may range from 33-52%. The main difficulty for the treatment of this disease is dealing with hypoxia.

Nitric Oxide inhalation therapy has proven to increase oxygenation and Ventilation/Perfusion by it's vasodilation property. However, there are several limitations for it's use, such as the need of a specialized equipment, systemic side effects, etc. The use of others vasodilation medications are not indicated due to their systemic systemic exposure and non-selective vasodilation.

BZ371B is a small peptide that acts as a NO synthase (NOS) enhancer, inducing local NO production, and is capable to present local vasodilation effect increasing blood flow regulation, by a new and innovative mechanism of action.
