About this study

Glucagon Like Peptide 1 Receptor Agonist (GLP1-RA) therapies have been introduced as antidiabetic drugs. In addition, GLP1-RA therapies reduce body weight, in patients with and without diabetes, without inducing hypoglycemia. Moreover, GLP1-RA reduce albuminuria in patients with type 2 diabetes, and liraglutide and semaglutide have been shown to improve various risk markers of CKD progression in non-diabetic obese individuals. It is therefore likely that these agents delay progression of kidney function decline in high risk obese/overweight, non-diabetic individuals.

The main objective of the study is to assess the albuminuria lowering effects of semaglutide 2.4 mg s.c. once weekly (Semaglutide 3 mg/ml) compared to placebo in obese/overweight non-diabetic individuals with elevated albuminuria. This will be tested in a 24-week randomized placebo controlled double-blind two arm parallel clinical trial with a 4 week wash-out period after 24 weeks double blind treatment to assess off drug effects.

Treatment and study plan

semaglutide

Drug

Patients will be treated for 24 weeks with semaglutide 3.0 mlg/ml s.c. once weekly. The starting dose of semaglutide will be 0.24 mg per week subcutaneous injection with increasing doses at 4, 8, 12, and 16 weeks to 0.5, 1,0, 1.7 and 2.4 mg.

Placebo

Drug

Patients will receive a matching placebo sc. once weekly during the treatment period of 24 weeks.
