About this study
This clinical trial aims to evaluate the safety and efficacy of REGEND001, an autologous basal layer stem cell transplantation therapy, in patients with chronic structural lung disease (bronchiectasis). The treatment involves harvesting bronchial basal layer stem cells from the patient, expanding them ex vivo, and reintroducing them via bronchoscopic infusion to repair damaged lung tissue.

- Bronchiectasis Adult
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
REGEND001 Autologous Basal Layer Stem Cell SuspensionBiological
REGEND001 Autologous Basal Layer Stem Cell Suspension is an innovative cell therapy product designed for chronic structural lung diseases, such as bronchiectasis. This treatment involves harvesting regenerative stem cells (expressing KRT5/P63 markers) from the patient's own bronchial basal layer via fiberoptic bronchoscopy. After isolation, purification, and ex vivo expansion, the cells are administered as a suspension through bronchoscopic infusion into damaged lung segments.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in DLCO from baseline.
The diffusing capacity of the lungs for carbon monoxide (DLCO) is a measurement of the gas transfer capacity of lung.
Measured: Baseline, 4 weeks post treatment, 24 weeks post treatment
Secondary outcomes (4)
Change in FEV1 from baseline
The forced expiratory volume in 1s (FEV1) is a measurement of the airflow capacity.
Measured: Baseline, 4 weeks post treatment, 24 weeks post treatment
Incidence of adverse events and serious adverse events.
Measured: Through study completion, an average of 6 months
Change in HRCT lung imaging scores
HRCT, high-resolution computed tomography.
Measured: Baseline, 4 weeks post treatment, 24 weeks post treatment
Quality of life (QoL) assessment via validated questionnaires
Score range: 0 to 100. Higher scores indicate a worse outcome.
Measured: Baseline, 4 weeks post treatment, 24 weeks post treatment

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing REGEND001 Autologous Basal Layer Stem Cell Suspension in people with Bronchiectasis Adult, run by Ruijin Hospital at 2 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 28 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in DLCO from baseline. (time frame: Baseline, 4 weeks post treatment, 24 weeks post treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jul 2026.
