Bosutinib as effective as nilotinib and dasatinib in frontline treatment of CML-CP

Key clinical point: Bosutinib demonstrated comparable efficacy to nilotinib and dasatinib for first-line treatment of newly diagnosed chronic-phase chronic myeloid leukemia (CML-CP).

Major finding: Besides bosutinib demonstrating better deep molecular responses, MR4 vs. nilotinib (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.38-0.84) and MR4.5 vs. dasatinib (OR, 0.56; 95% CI, 0.35-0.90) at 24 months, other parameters like major molecular response, complete cytogenetic response, and disease progression by 24 months were similar with bosutinib vs. nilotinib and dasatinib.

Study details: Unanchored matching-adjusted indirect treatment comparisons were performed using data from bosutinib (BFORE), nilotinib (ENESTnd), and dasatinib (DASISION) trials.
