Trial overview

Official title: A pharmacy based open study to evaluate whether pack size affects compliance for subjects diagnosed with diabetes type II who are established on metformin treatment
Trial description: MTF116086 is an open-label, randomised, parallel-design study in subjects with type II diabetes. The study is site-based, with local pharmacies serving as the sites and pharmacists as principal investigators for the sites. All subjects will enter an initial 8-week observational phase during which purchase behaviour and compliance with usual metformin use will be observed and recorded. At the end of the observational phase, subjects will be randomised to one of the two arms (metformin small pack vs. metformin large pack) for a 20-week interventional phase. The medication in the interventional phase is provided to the subjects free of charge. HbA1c will be collected for all subjects during Week 0, Week 8, and Week 28. Subjects will be asked questions about their tablet compliance, their satisfaction with the pack size they received and reasons for missing doses throughout the interventional phase by the pharmacist. The pharmacy visit on Week 28 will be end of the study.
