A Research Study Looking at the Safety of Multiple Doses of ZP8396 and How it Works in the Body of Healthy Participants

A Randomized, Multiple Ascending Dose Trial Assessing Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of ZP8396 Administered to Healthy Subjects

The trial is a single-centre, randomised and double-blind within cohorts, placebo-controlled, sequential multiple ascending dose trial in normal weight and overweight but otherwise healthy subjects randomised to subcutaneous administration of ZP8396 or placebo

The research study will investigate the safety and tolerability of ZP8396 in healthy study participants. In addition, the study will investigate how ZP8396 works in the body (pharmacokinetics and pharmacodynamics).

The trial is divided in two parts:

Part 1: 20 Participants will receive 6 once-weekly doses as an injection under the skin (subcutaneous, s.c.). Participants will have 14 visits with the study team. 6 of these visits consists of overnight stays of different duration (2-4 nights) at the study site. For each participant, the study will last up to 116 days.

Part 2: 48 Participants will receive 16 once-weekly doses as an injection under the skin (subcutaneous, s.c.) in a dose up-titration dose scheme. Participants will have 23 or 24 visits with the study team. 13 of these visits consists of overnight stays of different duration (2-4 nights) at the study site. For each participant, the study will last up to 198 days.
