Summary

This study tests a new oral drug called alvelestat (MPH966) in adults who have lung damage (bronchiolitis obliterans syndrome) after a stem cell transplant. The drug aims to block an enzyme that may cause lung injury. The trial has two parts: first to find the safest and most effective dose, then to see if that dose improves lung function over up to 12 months. Only 14 participants are enrolled, so results are very early.

What this could lead to

If it works, this could point toward a treatment to slow or improve lung damage in people with bronchiolitis obliterans syndrome after a stem cell transplant.

What could go wrong

This is an early, small trial with only 14 participants, so results may not apply to everyone. The drug may not improve lung function or could cause side effects.
