Indirect treatment comparisons of momelotinib vs pacritinib safety and anemia outcomes in patients with myelofibrosis.
To perform an indirect treatment comparison of safety and anemia outcomes between the Janus kinase (JAK) inhibitors momelotinib and pacritinib in patients with myelofibrosis. Treatment-emergent adverse events (AEs) and anemia outcomes were compared in a pooled population of JAK inhibitor - experienced and - naive patients treated with momelotinib (SIMPLIFY-1/SIMPLIFY-2/MOMENTUM) or pacritinib (PERSIST-2/PAC203). Momelotinib had statistically significantly lower odds and risk for all grades of diarrhea, nausea, peripheral edema, and vomiting as well as grade 3/4 and serious AEs vs pacritinib. Momelotinib-treated patients also had greater odds/possibility of hemoglobin improvement of ≥ 1 g/dL and clinical improvement in hemoglobin. Momelotinib provides a more favorable safety profile and a higher chance for hemoglobin improvement vs pacritinib.
