Can a new drug shield lungs from COVID-19's worst damage?

NCT ID NCT04472728

First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time

Summary

This trial tests whether an experimental drug called BIO101 can prevent severe breathing problems in hospitalized adults with COVID-19 pneumonia. Participants receive either BIO101 or a placebo for 28 days, and researchers track who develops respiratory failure, needs high-flow oxygen, or dies. The goal is to see if activating a protective pathway in the body can reduce the most dangerous complications of the infection.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
BIO101 (also called Sarconeos), an experimental drug that activates the Mas receptor to protect the lungs from severe damage
What this could lead to
If successful, BIO101 could become a treatment to prevent respiratory failure and reduce the need for mechanical ventilation in hospitalized COVID-19 patients.
What could go wrong
This is an early-to-mid-stage trial with a modest number of participants, so results may not be conclusive. The drug could also cause side effects or fail to show a clear benefit over placebo.
