Safety and tolerability of the treatment of youth-onset type 2 diabetes: the TODAY experience.

ABSTRACT: Data related to the safety and tolerability of treatments for pediatric type 2 diabetes are limited. The TODAY clinical trial assessed severe adverse events (SAEs) and targeted nonsevere adverse events (AEs) before and after treatment failure, which was the primary outcome (PO).Obese 10- to 17-year-olds (N = 699) with type 2 diabetes for <2 years and hemoglobin A1c (A1C) ? 8% on metformin monotherapy were randomized to one of three treatments: metformin, metformin plus rosiglitazone (M + R), or metformin plus lifestyle program (M + L). Participants were followed for 2-6.5 years.Gastrointestinal (GI) disturbance was the most common AE (41%) and was lower in the M + R group (P = 0.018). Other common AEs included anemia (20% before PO, 14% after PO), abnormal liver transaminases (16, 15%), excessive weight gain (7, 9%), and psychological events (10, 18%); the AEs were similar across treatments. Permanent medication reductions/discontinuations occurred most often because of abnormal liver transaminases and were lowest in the M + R group (P = 0.005). Treatment-emergent SAEs were uncommon and similar across treatments. Most (98%) were unrelated or unlikely related to the study intervention. There were no deaths and only 18 targeted SAEs (diabetic ketoacidosis, n = 12; severe hypoglycemia, n = 5; lactic acidosis, n = 1). There were 62 pregnancies occurring in 45 participants, and 6 infants had congenital anomalies.The TODAY study represents extensive experience managing type 2 diabetes in youth and found that the three treatment approaches were generally safe and well tolerated. Adding rosiglitazone to metformin may reduce GI side effects and hepatotoxicity.
