Clinical Trial Summary

The purpose of this study is to determine whether a non-hematopoietic erythropoietin analogue, ARA 290, exerts beneficial effects on blood glucose levels and insulin secretion in persons with prediabetes (impaired glucose tolerance, IGT, or impaired fasting glucose, IFG), or drug-naive type 2 diabetes.

The study will also evaluate effects of ARA 290 on insulin sensitivity and serum levels of inflammatory agents, e.g. cytokines. In addition, safety will be monitored by following parameters related to hematology, kidney and liver function and lipid levels.

Description:

Aims of the study:

The primary purpose of this double blind study is to determine in individuals with pre-diabetes (IGT, impaired glucose tolerance; or IFG, impaired fasting glucose) and drug-naïve type 2 diabetes whether ARA 290 reduces disease activity by improving oral glucose tolerance, and insulin secretion, and thereby improves long-term glucose control.

Secondary objectives are to evaluate the effects of ARA 290 on insulin sensitivity; serum levels of inflammatory agents, e.g. cytokine levels; serum levels of gluco-regulatory hormones, such as glucagon-like peptide-1 (GLP-1), glucagon; and safety by registering reported adverse events, and by monitoring clinical chemistry parameters related to hematology, kidney function, liver function and lipid levels.

Study Design:

This is a single-center, randomized, double-blind, placebo-controlled clinical trial to evaluate the effects of ARA 290 on glucose homeostasis in persons with pre-diabetes or early, dietary treated type 2 diabetes. The trial has two parallel arms with 12 subjects in each group, and with a 4-week-intervention period. At screening, a baseline investigation will include a physical examination and the following tests: oral glucose tolerance test (OGTT), and glycosylated hemoglobin (HbA1c).

The investigational medicinal product (ARA 290, 4.0 mg) or placebo will be self-administered by a once daily injection s.c. for 28 days. Participating subjects meeting inclusion criteria, and not fulfilling any exclusion criterion on screening, will be randomized double-blind within one week following screening 1:1 to either treatment with ARA 290 or with placebo. Before the first treatment, serum for determination of cytokines, adipokines, and hormones will be collected. Participants will be investigated further with OGTT, HbA1c and clinical assessment after 2 weeks and at study end, after 4 weeks. They should also perform a self-monitoring blood glucose (SMBG) curve once weekly during the treatment period, e.g., altogether 6 blood glucose tests during one day. Four weeks after the last dose, patients will return for HbA1c and fasting blood glucose levels.

The primary endpoint of the study is to test whether there is a significant difference between persons receiving ARA 290 vs. persons receiving placebo in: glucose tolerance, evaluated by OGTT at baseline, and after 2 and 4 weeks. . The secondary endpoints of the study include effects of ARA 290 on: insulin sensitivity, evaluated by HOMA-IR (homeostasis model assessment of insulin resistance); insulin secretion, examined both by measuring the early insulin response (at 15 and 30 min) in OGTT, and using the HOMA-beta (homeostasis model assessment of beta cell function); and long-term glucose control, determined as glycosylated hemoglobin, HbA1c; assessment of serum levels of inflammatory agents, e.g. cytokine levels; serum levels of gluco-regulatory hormones, such as glucagon-like peptide-1 (GLP-1), and glucagon; and safety by registering reported adverse events, and by monitoring clinical chemistry parameters related to hematology, kidney function, liver function and lipid levels.

Patients:

24 patients will be enrolled in one single center; 12 patients will be administered ARA 290 active ingredient product as daily doses for 28 days, and 12 patients will be administered a placebo as daily doses for 28 days. Individuals with IGT (impaired glucose tolerance), IFG (impaired fasting glucose) or drug-naïve type 2 diabetes will be included in the study. The population will consist of individuals of either gender, males aged 40-75 years; women aged 50-75 years and menopausal.
