- Fertile men agree to practice effective contraception during the study;

- Patients agree to comply with the study requirements and agree to come to the clinic for required study visits;

- Patients agree to follow medication restrictions during the study;

Exclusion Criteria:

- Expression of unusual BCR-ABL transcripts (other than e13a2 or e14a2);

- Pregnant or lactating women;

- Current use of digitalis;

- Current use of drugs which could influence bioavailability of inecalcitol (such as magnesium-containing antacids, bile-resin binders);

- Patients with a chronic condition which is not well controlled that, according to the investigator, would interfere with the completion of the study;

Intervention

Drug:
Inecalcitol
Prospective open label, non-comparative, multicentre exploratory study. Divided in 2 parts Part1: Inecalcitol treatment will be added to imatinib for 12 months. Part 2: Follow-up after discontinuation of inecalcitol. Imatinib will be maintained for 2 years and then will be stopped for those still in MR4.5. These patients will then be followed for 2 additional years after discontinuation of imatinib.
