Bronchiolitis obliterans after stem-cell transplant: causes and new treatments

Bronchiolitis Obliterans: Discovery and Therapy

NIH-funded research Dana-Farber Cancer Inst · NIH-11174489

This project tries a new drug called KD025 (a ROCK2 blocker) to help people who develop bronchiolitis obliterans after an allogeneic stem-cell transplant.

What this research studies

You would be offered a clinical treatment with KD025 aimed at the lung problems that happen after an allogeneic transplant. At the same time, researchers will grow human lung organoids and use immunogenomic tests to find which airway cells and antigens are being attacked. Insights from mouse models will guide which patients and doses might work best. The combined lab and clinical work aims to reduce airway fibrosis and improve breathing and survival.

Who could benefit from this research

Good fit: Ideal candidates are people who have bronchiolitis obliterans syndrome after an allogeneic hematopoietic cell (stem-cell) transplant.

Not a fit: People without transplant-related BOS, those with other unrelated lung diseases, or those with very advanced, irreversible lung damage may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this could slow or reverse lung scarring, improve breathing, and raise survival for people with post-transplant BOS.

How similar studies have performed: KD025 has shown promising activity for chronic graft-versus-host disease in prior work, but using it specifically to treat BOS is a new application being tested here.
