Effectiveness of Gilteritinib Beyond Second-Line Therapy in Relapsed/Refractory FLT3 -Mutated Acute Myeloid Leukemia: A Real-World Multicenter Study of 171 Patients.

ABSTRACT: Gilteritinib is a selective FLT3 inhibitor approved for the treatment of relapsed or refractory (R/R) FLT3-mutated acute myeloid leukemia (AML) following ≥ 1 prior line of therapy. However, data on its effectiveness in later-line settings is limited. We conducted a multicenter, retrospective study including 171 adult patients with R/R FLT3-mutated AML who received gilteritinib as third-line or beyond between August 2017 and March 2024 across centers in Italy, Spain, the United Kingdom, and Turkey. The primary endpoint was overall survival (OS). Secondary endpoints included overall response rate (ORR), composite complete remission (cCR), duration of response. Among the 171 patients, 84% carried FLT3-ITD mutations and 26% had received ≥ 3 prior lines of therapy. The cCR rate was 28%, and ORR
