CML: Adherence, persistence, and efficacy of second-line dasatinib and nilotinib

Key clinical point: Patients with chronic myeloid leukemia (CML) resistant or intolerant to imatinib showed superior 2-year adherence with second-line therapy dasatinib vs. nilotinib. Efficacy outcomes between both drugs were similar.

Major finding: Mean adherence calculated over 2 years was superior for dasatinib vs. nilotinib (0.91 vs. 0.82; P = .0043). Persistence for both drugs was 77%. At 2 years, 92% of patients were not in progression for both drugs (P = .02163).

Study details: This retrospective observational study evaluated 117 patients with CML treated with dasatinib (n = 70) or nilotinib (n = 47). Included patients showed resistance/intolerance to first-line treatment with imatinib.
