MorphoSys announced positive topline results from the Phase 3 MANIFEST-2 study evaluating pelabresib in combination with ruxolitinib compared to placebo plus ruxolitinib in JAK inhibitor-naïve adult patients with myelofibrosis.
The trial met its primary endpoint, as the combination therapy demonstrated a statistically significant and clinically meaningful improvement in the proportion of patients achieving at least a 35% reduction of spleen volume at week 24.
