As of 15 Aug 2019, 211 pts were randomized (n = 143, VEN; n = 68, PBO); median age: 76 yr in both arms (range: 36–93); secondary AML: 38% (88% post-MDS/CMML); prior hypomethylating agent: 20%. With a median follow-up of 17.5 mo (range: 0.1–23.5), median OS was 8.4 mo vs 4.1 mo in the VEN+LDAC and PBO+LDAC arms (HR 0.70; 95% CI 0.50–0.99; P= .04), representing a 30% reduction in the risk of death. Complete remission (CR)/CRi and CR/CRh (CR with partial hematologic recovery) rates were both 48% for the VEN+LDAC arm, and 13% and 15%, respectively, for PBO+LDAC. RBC/platelets TI rates were 43%/49% vs 19%/32% for VEN+LDAC and PBO+LDAC. Median EFS was 4.9 mo vs 2.1 mo in the VEN+LDAC and PBO+LDAC arms (HR 0.61; 95% CI 0.44–0.84; P= .003). Grade ≥3 adverse events (AEs [ > 30%]; VEN+LDAC/PBO+LDAC) included neutropenia (49%/18%), thrombocytopenia (45%/38%), and febrile neutropenia (32%/29%); serious AEs ( > 10%) were febrile neutropenia (17%/18%) and pneumonia (14%/10%); tumor lysis syndrome occurred in 5.6%/0%.


VEN+LDAC demonstrates a clinically meaningful improvement in OS compared with PBO+LDAC, with a tolerable and manageable safety profile. These data support VEN+LDAC as a frontline treatment option for older pts with AML, as well as those considered unfit for intensive chemotherapy.


Venetoclax + LDAC improved survival (mOS 8.4 vs 4.1 mos), after early and sustained remissions (mDOR 17 vs 8 mos).
