study to evaluate safety and efficacy of dapagliflozin in patients with type 2 diabetes mellitus aged 10-24 years

Conditions: Type 2 Diabetes

Summary: a trial of patients aged 10-24 years with type 2 diabetes mellitus to evaluate the comparative efficacy and safety between dapagliflozin and placebo.

a 24 week, multicenter, randomized, double-blind, parallel group, phase 3 trial with a 28 week long term safety extension period evaluating the safety and efficacy of dapagliflozin 10 mg in t2dm patients aged 10-24 years
