Abstract

Introduction: The prognosis of patients with refractory or relapsed AML (R/R-AML) is very limited. To (re)achieve complete remission, there has recently been increasing evidence that the combination of venetoclax (VEN) with chemotherapy is associated with improved outcomes.

Patients and methods: Our retrospective, single-center study of 53 R/R-AML patients with a median follow-up time of 11.0 months compared standard salvage chemotherapy (FLAG-Ida or HAM in n = 35 patients) with a combination of venetoclax (VEN) and FLAG-Ida (FLAVIDA in n = 18 patients) concerning safety and efficacy.

Results: Regarding the primary endpoints, there was a statistically significant increased event free survival (EFS) in the FLAVIDA group compared to patients with standard chemotherapy based on the univariate log-rank-test and in the multivariate Cox regression analysis (HR 0.22 [95% CI 0.05, 0.97]). There were no differences between the two groups in terms of patients developing febrile neutropenia CTCAE III° and IV° or a delay in hematological recovery. In addition, a clear trend towards an improved overall response rate (78% vs. 51%) was demonstrated in the FLAVIDA group.

Conclusions: The FLAVIDA regimen represents a promising treatment alternative for R/R AML patients with a high response rate and significantly improved EFS compared to standard chemotherapy.

Keywords: FLAVIDA; acute myelocytic leukemia (AML) leukemia; refractory; relapsed; venetoclax.

Figures

FIGURE 1
Kaplan–Meier curves of 6‐month event free survival (EFS) for n = 18 R/R AML patients receiving FLAVIDA (blue curve) compared to n = 35 receiving standard chemotherapy (red curve). EFS is the time from the start of treatment for R/R‐AML until refractory disease, relapse, or death, whichever occurred first. The EFS distributions differ significantly between the FLAVIDA and the standard chemotherapy group (p = 0.04, two‐sided log‐rank test).

Kaplan–Meier curves of 6‐month overall survival (OS) for n = 18 R/R AML patients receiving FLAVIDA (blue curve) compared to n = 35 with standard chemotherapy (red curve). OS is the time from the start of treatment for R/R‐AML to death. The OS differences in the distributions are not statistically significant (p = 0.27, two‐sided log‐rank test).
