Incyte Corporation announced new clinical data from two Phase 1 studies evaluating INCA033989, a first-in-class mutant calreticulin (mutCALR)-targeted monoclonal antibody, in patients with myelofibrosis. The studies assessed INCA033989 as a monotherapy in patients with CALR-mutated myelofibrosis who are resistant, intolerant, or ineligible for JAK inhibitor treatment, and in combination with ruxolitinib in patients with a suboptimal response to ruxolitinib monotherapy. The data, which were presented at the 2025 American Society of Hematology $(ASH)$ Annual Meeting in Orlando, showed improvements in symptom scores and reductions in mutCALR-positive cells. Incyte indicated plans to initiate a registrational program for INCA033989 in myelofibrosis in 2026.
