In terms of safety, the study revealed a low incidence of posttreatment toxicity in both treatment groups, with no new safety signals identified. The most frequently occurring grade 3 (≥ 2%) adverse events in patients receiving the venetoclax-based combination were neutropenia, thrombocytopenia, infusion-related reaction, anemia, febrile neutropenia, pneumonia, and leukopenia. Rates of secondary malignancy were numerically higher in certain solid organ tumors and melanoma in the venetoclax arm, said Dr. Al-Sawaf, but these differences were not statistically significant. Importantly, the incidence rate was similar between both arms, suggesting that there is no clinical difference in the risk of second malignancies. , In the CLL14 study, patients with previously untreated chronic lymphocytic leukemia (CLL) and coexisting conditions were randomized to 12 cycles of venetoclax-obinutuzumab (Ven-Obi, n = 216) or chlorambucil-obinutuzumab (Clb-Obi, n = 216). Progression-free survival (PFS) was the primary end point., Overall, the CLL13 and CLL14 trials support the use of 1‐year fixed‐duration Ven‐Obi in previously untreated CLL patients. These fixed‐duration regimens offer a more effective and less toxic first‐line therapy for patients with CLL, with sustained long‐term survival and quality of life benefits..
