BRIEF: Savara presents new data from the Phase 3 IMPALA-2 Clinical Trial of Molgramostim Inhalation Solution (Molgramostim) in patients with Autoimmune Pulmonary Alveolar Proteinosis (aPAP) at the European Respiratory Society (ERS) Congress 2025
Poster Summary:
DLco% (a measure of pulmonary gas transfer) was chosen as the primary endpoint in the IMPALA-2 Phase 3 clinical trial because it is a standardized measure of pulmonary gas transfer widely used in clinical practice
Previous research has shown that changes in DLco% correlate with changes in aPAP disease severity (i.e., surfactant accumulation/burden) and may predict the need for whole-lung lavage
Post-hoc correlation analyses of IMPALA-2 data were conducted to evaluate the relationship between DLco% and measures of HRQoL, patient functionality, and surfactant burden in patients with aPAP
Significant negative correlations were observed between DLco% and measures of respiratory HRQoL (SGRQ Total and Activity scores; higher scores indicate worse quality of life), as well as DLco% and surfactant accumulation (ground-glass opacity scores; lower scores indicate less surfactant) at Week 24. Significant positive correlations were observed between DLco% and patient functionality (exercise capacity expressed as peak METs; higher scores indicate improved exercise capacity) at Weeks 24 and 48
Results further support the clinical relevance of changes in DLco% in aPAP; changes in DLco% are associated with changes in clinical outcomes and the extent of pulmonary pathology, making it a clinically meaningful measure in this rare lung disease
