Assessment
Primary outcomes The incidence, type, and severity of adverse events will be compared between patients treated with alogliptin and patients not treated with any dipeptidyl peptidase-4 (DPP-4) inhibitor at the time of registration (between-group comparison) and among subgroups defined by patient baseline characteristics and by concomitant medications (between- subgroup comparison). All adverse events will be included in the safety evaluation, and major safety endpoints will include hypoglycemia, pancreatitis, skin disorder, infections, and cancer.
Key secondary outcomes Efficacy variables will be compared between patients treated with alogliptin and patients not treated with any DPP-4 inhibitor at the time of registration (between-group comparison) and among subgroups defined by patient baseline characteristics and by concomitant medications (between-subgroup comparison). The efficacy variables will include the changes from baseline (= time of registration) in the levels of hemoglobin A1c (HbA1c), fasting blood glucose, fasting insulin, and urinary albumin and the new onset and progression of microangiopathy.
