Trial in Progress: A Phase 3, Randomized, Double-Blind, Active-Control Study of Pelabresib (DAK539) Plus Ruxolitinib vs Placebo Plus Ruxolitinib in JAK Inhibitor-Naïve Adult Patients With Myelofibrosis (MANIFEST-3) (SOHO 2026) - Sep 1, 2026 - Abstract #MPN-555; Location: LEVEL 3, HALL B3; P3 | "MANIFEST-3 will build on the positive findings of MANIFEST-2 (NCT04603495) by evaluating efficacy and safety of PELA+RUX vs PBO+RUX in the broad population, including patients with higher symptom burden. This population may benefit more from PELA+RUX than RUX alone, aiming to address disease biology and achieve deeper, more durable spleen responses. AE: adverse event, ePROs: electronic patient-reported outcomes, MFSAF: Myelofibrosis Symptom Assessment Form, NF-κB: nuclear factor kappa-light-chain-enhancer of activated B cells, OS: overall survival, PFS: progression-free survival, QoL: quality of life."
