- Scientific TitleEffect of food on the pharmacokinetics of nilotinib in chronic myeloid leukemia: assessment of a tailored dose reduction (NiFo-study)
- ACRONYMNiFo-study
- hypothesisAs food increases nilotinib bioavailability, intake of nilotinib with medium fat Dutch food is expected to increase the bioavailability to an extent that it will allow a reduction of the daily dose by about 30 percent. This both reduces costs substantially and allows for increased adherence to nilotinib simultaneously.
- Healt Condition(s) or Problem(s) studiedChronic Myeloid Leukemia (CML), Nilotinib
- Inclusion criteria- Male or female patients at least 18 years of age; - Chronic Myeloid Leukemia in chronic phase; - Currently treated with nilotinib at 300 mg bid for at least 3 months; - Stable clinical status; - Written informed consent.

- InterventionsNilotinib at a lowered dose of 200 mg bid, administered with a meal for a period of seven days. The half-life of nilotinib is 17 hrs, which suggests that variability in pharmacokinetics, due to variability in the composition of meals, is limited. However, for safety reasons and to get insight into the effect of a high fat meal, patients will be asked to take nilotinib once with a high fat meal, to be planned at day seven (evening intake) of the seven day period of fed intake. A dietician will assist patients to select meals that fit into these guidelines.
- Primary outcomeThe difference in pharmacokinetic parameters AUC, Cmax, and Cmin between fasted and fed administration of nilotinib.
- Secondary outcomeInterpatient variability Intrapatient variability Patient-reported side effects Quality of life
- Timepoints1. Bloodsampling On day 1 and 3 of the four day period of fasted intake and on day 4 and 7 of the seven day period of fed intake: blood sampling at 1, 2, 3, 4, 6, 9 and 12 hrs after nilotinib intake in the morning, and 1, 2, 3 and 4 hrs after nilotinib intake in the evening and before the nilotinib intake of the next morning. On day 1 of the seven day period of fed intake: blood sampling at 1, 2 and 3 hrs after nilotinib intake. 2. Questionnaire At baseline and after the seven day period of fed intake. 3. Patient diary On day 1 and 3 of the four day period of fasted intake and on day 1-7 of the seven day period of fed intake.

- Brief summaryPrimary Objective: To evaluate the effect of real-life food consumption on the pharmacokinetics of nilotinib in CML patients. Exploratory Objective: To evaluate patient reported side effects and quality of life of CML patients using nilotinib at a lowered dose of 200 mg bid, administered with a meal. Study design: Intervention study with a pre-test post-test design, in chronic phase CML patients using nilotinib at a dose of 300 mg bid. The AUC, Cmax and Cmin of nilotinib, administered as recommended on an empty stomach during a period of four days, will be compared with the AUC, Cmax and Cmin of nilotinib 200 mg bid, administered with a meal for a period of seven days. Patient will be instructed about their meals. The study is non-invasive: nilotinib concentrations will be measured by means of the dried blood spot (DBS) sampling method. Patients will be asked to to complete a patient diary collecting data on the exact time of intake of nilotinib, exact time of blood sampling, consumption of food and side effects. Patients will be asked to fill out questions about quality of life. Overall study duration for the individual patient is 2 weeks.
