Pelabresib Plus Ruxolitinib for JAK Inhibitor-Naïve Patients: Data From MANIFEST and MANIFEST-2

Andrew Kuykendall, MD, and Raajit K. Rampal, MD, PhD, discuss how the combination of the BET inhibitor pelabresib and the JAK inhibitor ruxolitinib led to greater reductions in spleen size and symptoms compared to ruxolitinib alone in JAK inhibitor-naïve patients with intermediate- or high-risk myelofibrosis in the MANIFEST and MANIFEST-2 trials, with an acceptable safety profile, providing evidence that targeting multiple inflammatory pathways could lead to better disease control.
