Details and patient eligibility

About

To study the efficacy and safety of combination of Ro-Peg-interferon-α2b (RoPegIFN) with Bosutinib (BOS) in comparison to BOS monotherapy, as frontline therapy for newly diagnosed chronic myeloid leukemia patients, and to estimate efficacy of the addition of RoPegIFN to BOS in terms of deep molecular response with the aim of increasing the proportion of patients who may achieve treatment free remission.
