About

The goal of this clinical trial is to learn which dose of study drug IBIO-600 has the right balance of safety, tolerability and impact on body composition in overweight and obese adult participants.

Full description

The study is a single ascending dose study, with participants monitored for 9 months after administration.

This clinical trial will seek to address the following:

• Which dose of the study drug is most effective.
• How safe the study drug is and how well participants tolerate it.
• How much of the study drug can be found in blood (pharmacokinetics).
• How the study drug affects the body (pharmacodynamics).
• How the body's immune system responds to the study drug (immunogenicity).
• How the body's composition and physical function may change over the course of the study.
