Investigation on Safety, Tolerability and Pharmacokinetics of Single and Multiple Doses of a Long-acting GLP-1 Analogue (Semaglutide) in an Oral Formulation in Healthy Male Subjects

A maximum of six single-dose cohorts of oral semaglutide administered according to an ascending dose design. Starting dose 2 mg, max. dose 60 mg. Progression to next dose will be based on safety evaluation. Sequential cohorts.

Oral semaglutide administered as five multiple dose cohorts, where one of the cohorts will test a different dosing condition compared to the others. End doses from 10 mg/day to 60 mg/day. Progression to next dose will be based on safety evaluation. Semi-parallel cohorts.

In each cohort of 10, eight subjects will randomised to active treatment and two to placebo.

In each cohort of 24, 16 subjects will be randomised to active treatment, four to placebo and four to a enhancer-containing placebo (placebo C).
