Patients initiating generic imatinib achieved clinically significant improvements in adherence to TKI therapy relative to branded drug users, presumably due to lower out-of-pocket costs. Given the importance of optimal adherence in CML, considering barriers to adherence (eg, patient-cost sharing and health benefit design) when selecting initial treatment may improve long-term medication adherence. Pharmacoepidemiologic studies should consider how best to account for expected cost-sharing and its impact on adherence and subsequent clinical outcomes.
