Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 6 months or older undergoing allogeneic HSCT and referred for pulmonary function testing at Hadassah Ein Kerem Institute of Pulmonary Medicine.

Probably not a fit

Patients unable to perform FOT or who do not develop BOS or small airway disease may not experience a direct benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective study at Hadassah Medical Organization will compare Forced Oscillation Technique measurements with standard lung function tests in patients aged 6 months and older undergoing allogeneic HSCT. Participants will undergo FOT alongside spirometry, static lung volumes, and DLCO, with data collected on clinical and transplant characteristics and imaging. They will be followed for up to three years to evaluate FOT’s utility in diagnosis, monitoring, and treatment response for BOS and small airway disease after HSCT.

Why it matters

Potential benefit: If successful, FOT could provide a less invasive or more sensitive method to detect BOS early and monitor disease progression or treatment response.

How similar studies have gone: Prior studies in BOS and post-transplant lung disease suggest that complementary tests like FOT may add value, but this approach is exploratory in this setting.
