| Scientific title | A randomised Phase II trial of Imatinib (IM) versus Hydroxychloroquine (HCQ) and IM for patients with Chronic Myeloid Leukaemia (CML) in Cytogenetic Response (CyR) with residual disease detectable by quantitative polymer chain reaction (Q-PCR) |
| Study acronym | CHOICES - Chloroquine and imatinib combination to eliminate stem cells |
| Study objectives | 1. To provide preliminary evidence that hydroxychloroquine (HCQ) given in combination with imatinib is more effective than imatinib alone in terms of BCR/ABL levels in chronic myeloid leukaemia (CML) patients who are in moderate cytogenetic response (MCyR) with residual BCR/ABL+ cells after at least one year of imatinib treatment. 2. To determine the safety and tolerability of HCQ given in combination with imatinib in these patients. |
| Ethics approval(s) | West of Scotland REC 1, 01/12/2009, REC ref: 09/S0703/112 |
| Health condition(s) or problem(s) studied | Chronic myeloid leukaemia |
| Intervention | Imatinib alone arm: Patients will continue to receive the once-daily dose of imatinib (oral) that they were receiving prior to entry in the trial. This is the control arm of the study. Imatinib + HCQ arm: Patients will continue to receive the once-daily dose of imatinib (oral) that they were receiving prior to entry in the trial. In addition they will receive HCQ (oral), 400 mg twice-daily. This is the interventional treatment under study. Total duration of interventions: 12 months Total duration of follow-up: to be confirmed as of 24/08/2009 |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Phase II |
| Drug / device / biological / vaccine name(s) | Chloroquine, imatinib |
| Primary outcome measure | Proportion of treatment "successes" defined as patients who have ≥0.5 log reductions in their 12 month PCR level from baseline. Patients who withdraw before the 12 month assessment or who have an increase in their IM dose prior to the assessment will be classified as treatment "failures". All analyses will be conducted on an intention to treat basis. |
| Secondary outcome measures | 1. The proportion of treatment "successes" at 24 months. Again patients who withdraw or increase their IM dose prior to 24 months will be classified as treatment "failures". 2. Molecular response at 12 and 24 months (classified as Complete, Major and No response). Patients who withdraw or increase their IM dose prior to the assessment will be classified as non-responders. 3. The proportion of patients with progression at 12 and 24 months. Patients who withdraw or increase their IM dose prior to the assessment will be classified as progressing. All analyses will be conducted on an intention to treat basis. The comparisons between the study arms of "success", molecular response rates and progression rates will use Fisher's exact test. Adverse events will also be recorded throughout the trial. |

Concomitant use of any other anti-cancer therapy or radiation therapy 6. Female patients who are pregnant or breast feeding or patients of reproductive potential not willing to use a double method of contraception including a barrier method (i.e. condom) during the study and 3 months after the end of treatment 7.
