5. Study Description

Brief Summary
The ATTEMPT (Adolescent Type 1 diabetes Treatment with SGLT2i for hyperglycEMia & hyPerfilTration Trial) is a multi-center, double-blinded, randomized, placebo-controlled trial to evaluate the effect of treatment with Dapagliflozin when compared to placebo, in combination with adjustable insulin, on measured GFR in adolescents with T1D 12 to <19 years of age over a 16-week treatment period.
Detailed Description
The ATTEMPT (Adolescent Type 1 diabetes Treatment with SGLT2i for hyperglycEMia & hyPerfilTration Trial) is designed to evaluate the impact of Dapagliflozin versus placebo in combination with insulin therapy. This trial will assess detailed renal mechanistic evaluations, with direct measurement of GFR, to understand the important physiologic impacts of SGLT2 inhibition on the early onset manifestations and progression of diabetes complications within this age group. Fundamentally, the ATTEMPT trial will provide essential information in establishing a framework for this young cohort to evaluate key physiologic, mechanistic and metabolic outcomes.
