- Public TitleResponse and Adherence to Nilotinib in Daily Practice
- Scientific TitleResponse and Adherence to Nilotinib in Daily Practice
- hypothesisThe present study aims to get more insight into the efficacy of treatment with nilotinib and the various aspects that govern optimal response, of which adherence is a primary endpoint. We hypothesize that patients who are less adherent have a reduced cytogenetic and molecular response to nilotinib. In addition, patients with lower plasma levels of nilotinib may experience inadequate response levels.
- Healt Condition(s) or Problem(s) studiedChronic myeloid leukemia
- Inclusion criteria- Male or female patients 18 years of age;
- ECOG 0, 1, or 2;
- Patients with CML-CP within 6 months of diagnosis;
- Diagnosis of chronic myelogenous leukemia in chronic phase with cytogenetic confirmation of Philadelphia chromosome of (9;22) translocations;
- Ability to provide written informed consent prior to any study related screening procedures being performed.
- Exclusion criteria- Patients who are considered Ph negative because they do not have a confirmed cytogenetic diagnosis of Philadelphia chromosome of (9,22) translocation;
- Previously documented T315I mutations;
- Treatment with tyrosine kinase inhibitor(s) prior to study entry is not allowed, except in the following situation: in emergent cases where the patient requires disease management while awaiting study start, commercial supplies of Glivec at any dose may be prescribed to the patient but for no longer than 2 weeks in duration;
- Any medical treatment for CML prior to study entry for longer than 2 weeks with the exception of hydroxyurea and/or anagrelide ;
- All other criteria based on the treatment guidelines.

- Brief summaryBackground
The antitumor drug nilotinib has a large inter- and intra individual variability of pharmacokinetics. Adherence to treatment may substantially influence plasma levels and has been recognized as the most important determinant of treatment failure in CML. A better understanding of the various factors contributing to the efficacy of treatment is essential for the development of interventions to optimize the treatment of chronic phase chronic myeloid leukemia (CP-CML) with a protein kinase inhibitor like nilotinib.

In this multicenter prospective observational cohort study 70 newly-diagnosed intermediate and high risk CP-CML patients of 18 years and older starting treatment with nilotinib are followed up for at least 12 months. Response to treatment is evaluated after 3, 6 and 12 months. Adherence is primarily assessed by counting the daily intake of nilotinib capsules by means of a microelectronic monitoring system (MEMS). Before the start of nilotinib treatment and after 3, 6 and 12 months, patients are asked to fill in a comprehensive questionnaire including topics on quality of life, side effects, attitude towards disease and medication, the patients appreciation of information received about the medication, and discontinuation. After 3, 6 and 12 months of treatment, this will be supplemented by blood samples collected by finger prick to measure the trough plasma level of nilotinib.
