AbbVie Announces New Data on Chronic Lymphocytic Leukemia
AbbVie announced new Phase 3 data on a fixed-duration venetoclax-based combination at the European Hematology Association, or EHA, 2026 Congress taking place June 11-14 in Stockholm, Sweden. Final results from the Phase 3 CLL14 trial in previously untreated chronic lymphocytic leukemia, which was conducted in collaboration with the German CLL Study Group, will be featured in an oral presentation. A final analysis of the Phase 3 CLL14 trial, conducted in close collaboration with the German CLL Study Group, comparing venetoclax plus obinutuzumab to chlorambucil plus obinutuzumab in previously untreated patients with CLL and coexisting medical conditions, found that venetoclax plus obinutuzumab significantly improved progression-free survival compared to chlorambucil plus obinutuzumab, providing a limited-duration treatment option for unfit patients with previously untreated CLL. The nine-year analysis demonstrated the long-term off-treatment efficacy and safety of the venetoclax plus obinutuzumab fixed-duration combination, with the median time to next treatment of 7.6 years. After a median follow-up of 9.2 years, treatment with venetoclax plus obinutuzumab resulted in superior PFS compared to the obinutuzumab plus chlorambucil group, with median PFS of 6.4 years versus 3.2 years, respectively. The most frequently occurring Grade 3 adverse events, or AEs, in patients receiving the venetoclax-based combination were neutropenia, thrombocytopenia, infusion-related reaction, anemia, febrile neutropenia, pneumonia and leukopenia.
