Brief Summary
The aim of this single-center, prospective, randomized, double-blind, placebo-controlled, 2-arm parallel-group interventional study is to investigate the effect of 4-week treatment with AP-325 on C-peptide release as measure of insulin secretion compared to placebo in type 2 diabetes (T2D) patients.
