Is this trial a fit for you?

Likely a good fit

Adult males aged 18–60 with BMI 27.0–39.9 kg/m2 for MAD and 18–55 with BMI 20.0–29.9 kg/m2 for SAD, without significant medical abnormalities.

Probably not a fit

Participants with significant abnormal lab results or recent weight-management treatment may not benefit and could be excluded.

What this trial studies

This early-phase, randomized, double-blind study evaluates single ascending doses and multiple ascending doses of ZP6590 or placebo in healthy adults across weight groups. The trial has two parts: a SAD phase with single injections and a MAD phase with several weeks of dosing, each followed by observation periods. Primary aims are safety, tolerability, plus pharmacokinetics and pharmacodynamics, to determine dose escalation safety and how the drug is absorbed, distributed, metabolized, and eliminated.

Why it matters

Potential benefit: If successful, participants may experience information that supports safe dose ranges for future studies of ZP6590 in obesity.

How similar studies have gone: Previous early-phase studies with GIP-R agonists have gathered safety and PK data in humans, supporting this approach's feasibility but each agent is evaluated separately.
