Condition chronic myeloid leukemia
Treatment nilotinib
Phase phase 2
Targets BCR-ABL, KIT, PDGF

Start date December 2012
End date January 2019
Trial size 163 participants
Trial identifier NCT01698905, CAMN107A2408

Summary

A clinical research study to find out if it is safe to stop the drug nilotinib (Tasigna) in chronic myeloid leukemia (CML) patients. Patients who started treatment with imatinib (Gleevec) when they were first diagnosed with CML, then switched to nilotinib (Tasigna) for at least 2 years with the combined time on imatinib (Gleevec) and nilotinib (Tasigna) for at least 3 years and have very small amount of leukemia cells remaining after the nilotinib (Tasigna) treatment will qualify for the study.

Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
Arm
(Experimental)
70 patients who maintain MR4.5 during the one year nilotinib consolidation phase will stop treatment when they enter the treatment-free remission (TFR) phase
nilotinib
Nilotinib will be labeled as AMN107 and supplied as 150 mg and/or 200 mg hard gelatin capsule. Nilotinib will not be dosed by weight or body surface area. Nilotinib will be administered orally at 300 mg twice daily (BID) or 400 mg BID, at approximately 12 hour intervals, and must not be taken with food. The capsules should be swallowed whole with water. No food should be consumed for at least 2 hours before the dose is taken and no additional food should be consumed for at least one hour after the dose is taken. Patients who were previously treated with 400 mg BID, and required subsequent permanent dose reduction to 400 mg QD will be allowed to enter this study on the same dose, 400 mg once daily.

Patients must have the following electrolyte values ≥ LLN (lower limit of normal) limits or corrected to within normal limits with supplements prior to the first dose of study medication: - Potassium - Magnesium - Total calcium (corrected for serum albumin) 9. Patients must have normal marrow function as defined below: - Absolute Neutrophil Count (ANC) ≥ 1.5 x 109/L - Platelets ≥ 100 x 109/L - Hemoglobin ≥ 9.0 g/dL 10.

Acceptable forms of highly effective contraception methods include: a. Total abstinence (when this is in line with the preferred and usual lifestyle of the patient.
