A randomised Phase II trial of Imatinib (IM) versus Hydroxychloroquine (HCQ) and Imatinib (IM) for patients with Chronic Myeloid Leukaemia (CML) in Cytogenetic Response (CyR) with residual disease detectable by quantitative polymerase chain reaction (Q-PC

To provide preliminary evidence that HCQ given in combination with imatinib is more effective than imatinib alone in terms of BCR/ABL levels in CML patients who are in major cytogenetic response with residual BCR/ABL+ cells after at least one year of imatinib treatment. To determine the safety and tolerability of HCQ given in combination with imatinib in these patients.
