Phase I/II Clinical Trial of Axatilimab, a CSF1R Monoclonal Antibody, in Combination With Ruxolitinib as Therapy for Patients With Myelofibrosis (MF) and Chronic Myelomonocytic Leukemia (CMML)

Is NCT07128381 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments including Axatilimab (SNDX-6352) and Ruxolitinib for myelofibrosis (mf).

Phase 1/2RecruitingM.D. Anderson Cancer CenterNCT07128381Data as of May 2026

Treatment: Axatilimab (SNDX-6352) · Ruxolitinib* To find the recommended dose of axatilimab given alone and in combination with ruxolitinib in patients with MF and CMML. * To learn if axatilimab given in combination with ruxolitinib can help to control MF and CMML.
