Official title

Tagraxofusp (SL-401) in Patients With Chronic Myelomonocytic Leukemia (CMML)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This multicenter, multi-arm trial evaluated the safety and efficacy of tagraxofusp, a cell division cycle protein 123 homolog-targeted therapy, in participants with either CMML or MF. There were 2 CMML cohorts, 1 enrolled participant with CMML (CMML-1 or CMML-2) who were refractory/resistant or intolerant to hypomethylating agents (HMA), hydroxyurea (HU), or intensive chemotherapy and 1 enrolled treatment-naive participants with CMML (CMML-1 or CMML-2) with molecular features associated with poor prognosis. The MF cohort enrolled participants who were resistant/refractory or intolerant to approved Janus kinase (JAK) therapy (JAK1/JAK2 or JAK2).
