Lung cell therapy shows promise in IPF trial
NCT ID NCT06081621
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new cell therapy called REGEND001 for people with idiopathic pulmonary fibrosis (IPF), a serious lung disease. The therapy uses special lung cells to try to repair damaged tissue. In this phase 2 trial, 23 participants received either the cell therapy or a placebo to see if it could improve lung function over 24 weeks.
