ABSTRACT
BACKGROUND:
This retrospective cohort study used an electronic health record-derived, de-identified, US patient-level database to better understand the real-world treatment experience, in a predominantly community setting (80.3% of patients), of venetoclax+hypomethylating agents (HMAs) in routine clinical care, pre- and post-VIALE-A, to determine whether the post-remission cytopenia management insight from VIALE-A was reflected in real-world clinical practice.METHODS:
Patients with newly diagnosed acute myeloid leukemia (AML; N = 498), who initiated venetoclax+HMA ≤30 days from AML diagnosis from June 1, 2018, to March 31, 2021, were stratified into pre-(n = 330) and post-(n = 168) VIALE-A cohorts.RESULTS:
More patients in the post-(61%) versus pre-(45%) VIALE-A cohort had their first biopsy by 28 ± 14 days post-treatment initiation. Patients underwent bone marrow (BM) assessment earlier in the post- versus pre-VIALE-A cohort, and first identification of response was also earlier (2.5 vs 5.1 months, respectively). More venetoclax schedule modifications post-remission occurred among post-(82.1%) versus pre-(73.8%) VIALE-A responders; the most common reason for modification was treatment toxicities, specifically cytopenia. Treatment survival outcomes were comparable with or without venetoclax schedule modifications.CONCLUSIONS:
Findings suggest that venetoclax schedule modifications can be used to manage cytopenia events without adversely affecting outcomes. Opportunities remain to improve earlier BM assessment to determine venetoclax schedule modifications, providing the best chance for optimal treatment outcomes.
