Roche announces full FDA approval for Venclexta combinations for acute myeloid leukaemia - Seite 2
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.
“The results of the VIALE-A study reinforce the clinically meaningful benefit of Venclexta plus azacitidine for people newly diagnosed with AML,” said Courtney DiNardo, M.D., Associate Professor of the Department of Leukemia, Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center. “Based on the results of this study, this treatment regimen represents a significant advance for older AML patients, including higher response rates, greater transfusion independence, longer durations of remission, and ultimately significantly improved overall survival compared to azacitidine alone.”
This is the second time that Venclexta has been reviewed under the FDA’s new Real-Time Oncology Review (RTOR) and Assessment Aid pilot programmes. The RTOR pilot programme explores a more efficient review process to ensure safe and effective treatments are available to patients as early as possible. The approval was also granted under the FDA’s recently established Project Orbis, which provides a framework for concurrent submission and review of oncology medicines among multiple regulatory agencies worldwide. Simultaneous applications were submitted to regulators in the US, Australia, Canada, Brazil and Switzerland under Project Orbis. Additionally, the FDA has granted five Breakthrough Therapy Designations for Venclexta, two of which are for people with previously untreated AML ineligible for intensive chemotherapy.
