Autologous bronchial basal cell transplant to treat COPD

Official title: REGEND001 Autologous Basal Layer Stem Cell Transplantation for Chronic Obstructive Pulmonary Disease (COPD): A Translational Application Study

Run by Ruijin Hospital · NCT06946953 · Data updated 2026-11-12

This trial tests whether a patient’s own bronchial basal cells, expanded in a lab, can be safely infused into their lungs to improve lung function in COPD.

Is this trial a fit for you?

Likely a good fit

Adults with COPD (per GOLD 2021), with post-bronchodilator FEV1/FVC < 70% and DLCO between 20% and 80% predicted.

Probably not a fit

Patients with severe comorbidities, active infection, pregnancy, or past/present malignancy may not benefit or be eligible for this therapy.

What this trial studies

This early-phase study evaluates safety and potential benefit of REGEND001, a therapy using a patient’s own bronchial basal cells. Cells are collected by bronchial brushing, expanded, and reintroduced into the lungs via bronchoscopy. The primary goal is to see if diffusion capacity (DLCO) improves, with secondary measures including lung ventilation and other lung function parameters. The study includes participants with COPD who meet specific lung function criteria and excludes those with certain infections or prior cancers. Conducted at Ruijin Hospital and affiliated sites in Shanghai and Hainan, the trial spans Phase 1 and Phase 2 to explore feasibility and preliminary efficacy.

Why it matters

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

How similar studies have gone: Preclinical data support tissue repair potential, but clinical results for autologous basal cell therapies in COPD are exploratory and limited.
