Application of Transbronchial Cryobiopsy in the Diagnosis of Progressive Pulmonary Fibrosis

Study Purpose

The goal of this clinical study is to learn about the diagnostic effectiveness, safety, and influencing factors of transbronchial cryobiopsy(TBLC)in progressive pulmonary fibrosis. The main question it aims to answer are: • Determine the prognosis, health economics, and therapeutic strategy changes of patients with TBLC retrograde malleable pulmonary fibrosis. Participants will be randomly divided into two groups, and received TBLB or TBLC.

Recruitment Criteria

Accepts Healthy Volunteers

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

No
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.

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.

NCT06251687
Phase

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.
