Using Dapagliflozin to Treat Chronic Kidney Disease in Young People

DOUBLE PRO-TECT Alport: a Confirmatory, Multicenter, Randomized, Double-blind, Placebo-controlled Clinical Trial to Assess the Effect of Dapagliflozin on the Progression of Chronic Kidney Disease in Adolescents and Young Adult Patients with Alport Syndrome

Phase 3 Interventional University Hospital Goettingen · NCT05944016

This study is testing if the medication dapagliflozin can help young people with Alport syndrome and early chronic kidney disease slow down kidney damage and reduce protein in their urine.

What this trial studies

This clinical trial aims to evaluate the effectiveness of dapagliflozin, a sodium-glucose co-transporter-2 inhibitor, in preventing the progression of chronic kidney disease (CKD) in adolescents and young adults diagnosed with Alport syndrome. The study will compare the effects of dapagliflozin against a placebo in patients with early stages of CKD, focusing on reducing albuminuria and delaying the onset of end-stage kidney failure. By establishing the safety and efficacy of this treatment in a pediatric population, the trial seeks to address a significant unmet medical need in this demographic.

Who should consider this trial

Good fit: Ideal candidates include adolescents aged 10 to 18 years or young adults aged 18 to 40 years with early-stage Alport syndrome and specific levels of albuminuria.

Not a fit: Patients with advanced CKD, requiring dialysis, or those with uncontrolled hypertension may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly delay the progression of kidney disease and improve the quality of life for affected young patients.

How similar studies have performed: Previous studies have shown positive outcomes with SGLT2 inhibitors in adult populations, but this approach in children is novel and untested.
