Abstract

Background: Since there are few treatment options for young people with type 2 diabetes, we aimed to assess the efficacy and safety of dapagliflozin as add-on therapy in children, adolescents, and young adults with type 2 diabetes receiving metformin, insulin, or both.

Methods: This multicentre, placebo-controlled, double-blind, randomised phase 3 study was undertaken at 30 centres in five countries (Hungary, Israel, Mexico, Russia, and the USA). Participants aged 10-24 years with type 2 diabetes and HbA1c concentration of 6·5-11% (48-97 mmol/mol) were randomly assigned 1:1 to oral dapagliflozin 10 mg or placebo during a 24 week double-blind period, which was then followed by a 28 week open-label safety extension in which all participants received dapagliflozin. Participants and study personnel were masked and participants were randomly assigned treatment (placebo or study drug) using an interactive web and voice response system. The primary outcome was between-group differences in change in HbA1c concentration from baseline to 24 weeks (intention-to-treat analysis). A prespecified sensitivity analysis of the primary outcome was also assessed in the per-protocol population, which included only protocol-compliant participants. This trial is registered with ClinicalTrials.gov, NCT02725593.

Findings: Between June 22, 2016, and March 15, 2019, 72 participants (19 [26%] of whom were aged 18-24 years) were randomly assigned (39 to dapagliflozin and 33 to placebo). Mean age was…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 13 participants or records.
