No margin for non-adherence: Probabilistic kaplan-meier modeling of imatinib non-adherence and treatment response in CML (ADAGIO study).

Background: Although adherence to imatinib is critical for attaining treatment responses in chronic myeloid leukemia, there is evidence of varying adherence among patients. Our aim was to model and determine the margin of tolerance, if any, required to ensure treatment responses among patients prescribed imatinib before treatment response is at risk.

Method: We performed post hoc analyses of the ADAGIO study conducted in Belgium on 169 evaluable patients (Blood 2009).

Nonadherence to imatinib treatment in patients with gastrointestinal stromal tumors: the ADAGIO study.

Aim: To determine imatinib nonadherence rates in patients with gastrointestinal tumors (GIST) over 90 days.

Patients And Methods: A prospective 90-day observational, open-label, multicenter study was carried out of 28 evaluable GIST patients on imatinib. Nonadherence behavior was measured using a 4-item patient interview.

Prevalence, determinants, and outcomes of nonadherence to imatinib therapy in patients with chronic myeloid leukemia: the ADAGIO study.

Imatinib mesylate (imatinib) has been shown to be highly efficacious in the treatment of chronic myeloid leukemia (CML). Continuous and adequate dosing is essential for optimal outcomes and with imatinib treatment possibly being lifelong, patient adherence is critical. The ADAGIO (Adherence Assessment with Glivec: Indicators and Outcomes) study aimed to assess prospectively over a 90-day period the prevalence of imatinib nonadherence in patients with CML; to develop a multivariate canonical correlation model of how various determinants may be associated with various measures of nonadherence; and to examine whether treatment response is associated with adherence levels.

Imatinib for the treatment of patients with unresectable or metastatic malignant KIT-positive gastrointestinal stromal tumours: an open-label Belgian trial.

Background: Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumours of the gastrointestinal tract. They are defined immunohistologically as KIT positive tumours. The only effective treatment for malignant GIST was surgery until 2000.
