A Two-Part First-In-Human Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of GUB014295

A Two-Part First-in-Human Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single and Multiple Ascending Subcutaneous Doses of GUB014295 in Lean to Overweight or Obese But Otherwise Healthy Men and Women

This is a two-part, single centre, double-blind (within cohorts), randomised, placebo-controlled, single (Part 1) and multiple (Part 2) ascending subcutaneous dose study in lean to overweight or obese but otherwise healthy men (Part 1) and men and non-pregnant, non-lactating women (Part 2). The primary objective is to assess the safety and tolerability. Secondary objectives are to characterize the pharmacokinetics (PK) and to investigate pharmacodynamic effects.

Study Overview

• Status: Completed
• Conditions: Overweight; Healthy Volunteers
• Intervention / Treatment: Drug: GUB014295-PLACEBO; Drug: GUB014295

Detailed Description

This is a phase 1 clinical trial of a new long-acting amylin analogue GUB014295 in two parts.

Trial design: Part 1 is a double-blind (within cohorts), randomised, placebo-controlled, single ascending dose (SAD) study. It is planned to enrol 4 cohorts of 8 subjects (Regimens A, B, C and D), with 2 additional optional cohorts of 8 subjects (Regimens E and F). Part 2A is a double-blind (within cohorts), randomised, placebo-controlled, multiple ascending dose (MAD) study. It is planned to enrol 2 cohorts of 8 subjects (Regimens G and H). Part 2B is a double-blind (within cohorts), randomised, placebo-controlled, MAD study.

It is planned to enrol 3 cohorts of 12 subjects (Regimens I, J and K). Part 2C is a double-blind (within cohorts), randomised, placebo-controlled, MAD study. It is planned to enrol 2 cohorts of up to 12 subjects (Regimens L and M).

The primary objective is to assess the safety and tolerability of a new long-acting amylin-analogue GUB014295. Secondary objectives are to characterize the pharmacokinetics (PK) of the long-acting amylin-analogue GUB014295 and to investigate if the long-acting amylin-analogue GUB014295 has possible pharmacodynamic effects measured as weight changes and changes in gastric emptying (paracetamol concentration) and changes in glucose, insulin, C-peptide, and glucagon during a mixed meal test.
