Clinical Trial Summary

This is a randomised, double-blind, four-period crossover euglycaemic clamp trial in subjects with type 2 diabetes.

Each subject will be randomly allocated to one of four treatment sequences. Each sequence will comprise 3 different single doses of BC Combo THDB0207 (Low dose, Medium dose, and High dose) and one single dose of Humalog® Mix25.

Subjects will come to the clinical trial centre in a fasted state in the morning of each dosing day and stay at the clinical trial centre until the 30-hour clamp procedures have been terminated.

Description:

Subjects will attend the study site in the morning in a fasted state and will be connected to an automated glucose clamp device. Prior to dose administration plasma glucose will be stabilised at a target level of 100 mg/dL by means of an intravenous infusion of glucose or insulin. IMP administration will be done by an unblinded person by means of subcutaneous injections in the abdominal wall.

Following each dosing a euglycaemic glucose clamp procedure will be carried out for up to 30 hours.

The pharmacodynamic assessment will be based on the time course of glucose infusion rate (GIR) and plasma glucose.

Plasma insulin concentrations will be measured using a specific validated bioanalytical method differentiating concentrations of insulin glargine, of its main metabolites insulin-glargine-M1 and insulin-glargine-M2, and of insulin lispro. Pharmacokinetic assessments will be based on total insulin concentration (insulin glargine + insulin glargine-M1 + insulin glargine-M2 + insulin lispro), on insulin glargine concentration (insulin glargine + insulin glargine-M1 + insulin glargine-M2), or on insulin lispro concentration.
