NCT06072326 | NOT YET RECRUITING | Type 1 Diabetes Mellitus With Diabetic Nephropathy

Ambrisentan Sotagliflozin and Prevention of Renal Injury; a Randomized Evaluation
Sponsor:

University Medical Center Groningen

Brief Summary:

The aim of this study is to test the hypothesis that sotagliflozin (SGLT1/2 inhibitor) and ambrisentan (ERA) combination therapy augments nephroprotection and mitigates fluid retention and ketogenesis in people with T1D through complementary and synergistic mechanisms of actions.

Phase

PHASE2

Detailed Description:

A phase 2, multicenter, randomized, open-label, cross-over trial will be conducted in male or female individuals (N=36) diagnosed with type 1 diabetes at least 6 months prior to informed consent aged between 18 and 65 years, Body Mass Index (BMI) ≥ 21 kg/m2, urinary albumin:creatinine ratio ≥ 50 mg/g and \< 3000 mg/g, eGFR \> 30 and \<90 ml/min/1.73m2 and HbA1c between 6.5 and 10.0%. Patients have to be on stable RAAS inhibition for at least 4 weeks prior to screening. The study will consist of a screening visit, a 4-week run-in phase. After the run-in phase, the participant will be randomized to treatment of ambrisentan, sotagliflozin or their combination in random order. The duration of each treatment period is 4 weeks with study visits scheduled at 2 and 4 weeks in each treatment period. At the end of each treatment period patients proceed to a 4 weeks wash-out phase to study off drug effects. The total duration of the study for each participant after randomization is thus 24 weeks Interventions Ambrisentan 2.5 mg once daily; sotagliflozin 200mg once daily; combination of ambrisentan 2.5mg once daily and sotagliflozin 200mg once daily
