About

The primary purpose of the study is to evaluate the efficacy and safety of APHD-012 (distal jejunal-release dextrose [Aphaia technology, AT]) in participants with pre-diabetes (pathological Oral Glucose Tolerance Test (OGTT)).

Full description

The goal of this Phase II, Randomized, Placebo-Controlled Crossover Proof-of-Concept Study is to evaluate the efficacy of APHD-012 in patients with pre-diabetes (pathological Oral Glucose Tolerance Test (OGTT)). The main questions it aims to answer are:

1. Are there changes in baseline in Area Under the Curve from Time 0 to 2 Hours (AUC0-2) values of Oral Glucose Tolerance Test (OGTT)?
2. Are there changes in biomarkers (e.g. fasting plasma glucose, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR))?

Participants will receive study medication or placebo once daily for 6 weeks, followed by washout period of 4 weeks, and subsequent crossover to the other treatment arm for 6 weeks.

Enrollment: 31 patients

• Prior or current treatment with drugs aimed to treat abnormal glucose homeostasis including oral antidiabetics, incretin analogues and/or insulin.

• History of uncontrolled illness (e.g. depression, psychosis) or behaviour that at the discretion of the investigator might confound the study results or pose additional risk in administering the study procedures.
