Autologous Basal Layer Stem Cells for Interstitial Lung Disease

Official title: REGEND001 Autologous Basal Layer Stem Cell Transplantation for Interstitial Lung Disease (ILD): A Translational Application Study

Run by Ruijin Hospital · NCT06998706 · Data updated 2026-11-12

This study tests whether a patient’s own bronchial basal layer stem cells can be safely infused to help people with interstitial lung disease feel better or improve lung function.

Is this trial a fit for you?

Likely a good fit

Adults aged 40–75 with confirmed ILD (including IPF or connective tissue disease–associated ILD) and DLCO between 30% and 80% predicted.

Probably not a fit

Patients with active malignancy, unresolved infections, pregnancy plans, or contraindications to bronchoscopic procedures may not benefit and could be excluded or experience risks without clear gains.

What this trial studies

This first-in-human translational study uses autologous basal layer stem cells (expressing KRT5/P63) harvested from patients, expanded outside the body, and delivered to the lungs via bronchoscopic infusion. The aim is to assess safety and potential efficacy in regenerating damaged lung tissue in ILD. Eligible adults are 40–75 with confirmed ILD and specific lung function criteria, excluding those with active cancer or certain infections. Multiple sites in Shanghai and Hainan will enroll participants under a lead sponsorship from Ruijin Hospital. The approach represents a procedures-based cell therapy with careful patient selection and close monitoring for adverse events and early signals of benefit.

Why it matters

Potential benefit: If successful, patients may experience stabilized or improved lung function and potentially slower disease progression.

How similar studies have gone: Early translational studies in cell-based lung therapies have shown safety signals, but this approach is novel for ILD and requires demonstration of both safety and efficacy signals.
