Using cryobiopsy to diagnose progressive pulmonary fibrosis

Official title: Application of Transbronchial Cryobiopsy in the Diagnosis of Progressive Pulmonary Fibrosis:a Multicenter Prospective Study

Run by China-Japan Friendship Hospital · NCT06251687 · Data updated 2026-11-12

This study is testing a new lung biopsy method called cryobiopsy to see if it can diagnose progressive pulmonary fibrosis better and safer than the traditional method.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with progressive pulmonary fibrosis and specific lung function criteria.

Probably not a fit

Patients with severe coagulopathy or those who do not meet the inclusion criteria will not benefit from this study.

What this trial studies

This clinical study aims to evaluate the diagnostic effectiveness and safety of transbronchial cryobiopsy (TBLC) in patients with progressive pulmonary fibrosis (PPF). Participants will be randomly assigned to receive either TBLC or traditional transbronchial lung biopsy (TBLB) to compare outcomes. The study will also assess the prognosis, health economics, and potential changes in therapeutic strategies for patients diagnosed with PPF using TBLC. The findings could provide valuable insights into the best diagnostic approaches for this condition.

Why it matters

Potential benefit: If successful, this study could improve diagnostic accuracy and treatment strategies for patients with progressive pulmonary fibrosis.

How similar studies have gone: While there is ongoing research in the field of pulmonary fibrosis diagnostics, the specific application of transbronchial cryobiopsy in this context is relatively novel.
