Combination of Midostaurin and Gemtuzumab Ozogamicin in First-line Standard Therapy for Acute Myeloid Leukemia (MOSAIC)

Is NCT04385290 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments for acute myeloid leukemia.

Phase 1/2RecruitingTechnische Universität DresdenNCT04385290Data as of May 2026

Treatment: MODULE: conventional chemotherapy (Cytarabine+Daunorubicin) in combination with midostaurin+GO · MAGNOLIA-trial: Midostaurin associated with conventional chemotherapy (AraC+DNR)+GO · MAGNOLIA-trial: conventional chemotherapy (AraC+DNR)+GO · MAGMA-trial:GO associated with conventional chemotherapy (AraC+DNR)+Midostaurin · MAGMA-trial: conventional chemotherapy (AraC+DNR)+MidostaurinThis phase I/II clinical trial evaluates the safety and efficacy of the combined administration of midostaurin and gemtuzumab ozogamicin in the frame of first-line standard chemotherapy in newly diagnosed acute myeloid leukemia (AML) patients displaying a cytogenetic aberration or fusion transcript in the core-binding factor (CBF) genes or FMS-like tyrosine Kinase 3 (FLT3) mutation.
