The approval is primarily based on the results of two phase III studies, VIALE-A and VIALE-C. Results of the VIALE-A study, which were published in the New England Journal of Medicine in August 2020, showed Venclexta plus azacitidine significantly reduced the risk of death by 34% (overall survival; OS) compared to azacitidine alone (median OS=14.7 months vs. 9.6 months; HR=0.66; 95% CI: 0.52-0.85; p<0.001). People treated with Venclexta plus azacitidine had significantly higher rates of complete remission (CR) with 37% (95% CI: 31-43) compared to 18% (95% CI: 12-25) in people treated with azacitidine alone (p<0.001). The Venclexta plus azacitidine combination also led to higher rates of CR and CR with partial haematologic recovery (CR + CRh), with the combination showing a CR + CRh of 65% compared to 23% with azacitidine alone (p<0.001). The most frequent serious adverse reactions (≥5%), reported in 83% of people treated with Venclexta plus azacitidine, were low white blood cell count with fever (30%), pneumonia (22%), blood infection (excluding fungal;19%), and bleeding (6%).For the VIALE-C study, the approval was based on the rate and duration of CR. Twenty-seven percent (95% CI: 20-35) of people treated with Venclexta plus LDAC achieved a CR (median duration of CR (DOCR)=11.1 months) vs. 7.4% (95% CI: 2.4-16) of people treated with LDAC alone (median DOCR=8.3 months). The median OS for people treated with Venclexta plus LDAC was 7.2 months vs. 4.1 months (HR=0.75; 95% CI: 0.52-1.07; p=0.114) for people treated with LDAC alone. These OS results were not statistically significant. The most frequent serious adverse reactions (≥10%), reported in 65% of people treated with Venclexta plus LDAC, were pneumonia (17%), low white blood cell count with fever (16%), and blood infection (excluding fungal;12%).Updated results from additional phase I/II studies of Venclexta in people with newly diagnosed AML were included in the FDA submissions as supporting data.
