PATIENTS Point 1: the most recent (successful) trials moved towards centralized review of diagnostic criteria Point 2: there is a risk of narrowing too much the population of patients enrolled in trials Point 3: some recent “deviations” have been explored and can inform future trials ©2015 Pulmonary Fibrosis Foundation.

END POINTS Point 1: change in FVC over 1 year has been the basis for recent approvals: challenging in the presence of a comparator arm Point 2: enrichment strategies (particularly in the context of target therapies) might be helpful Point 3: patient-reported outcomes remain an ideal end-point, but a challenging research area ©2015 Pulmonary Fibrosis Foundation.
