Autologous Bronchial Basal Cells Transplantation for Treatment of CRD Including COPD, BE and PF

Study Purpose

Chronic respiratory diseases including chronic obstructive pulmonary disease (COPD), bronchiectasis (BE) or pulmonary fibrosis (PF) are usually not curable with damaged pulmonary structure and function. Bronchial basal cells are proved to regenerate bronchus and alveoli to repair the pulmonary injuries. In this study, we intend to perform an open, single-armed phase I clinical trial by transplantation of autologous bronchial basal cells on patients suffered from COPD, BE or PF. During the treatment, autologous bronchial basal cells, which were isolated from fiberoptic bronchoscopy and expanded in vitro, will be injected directly into lesions by fiberoptic bronchoscopy after careful characterization. In the following 6 months, the safety and efficacy of the treatment will be monitored by measuring the key clinical indicators.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years - 75 Years
Gender All

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
