About

The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of LAE103 injection in healthy overweight/obese participants or healthy postmenopausal women. Study will also evaluate the safety, tolerability and preliminary pharmacodynamic effect of multiple dose injections in overweight/obese participants.

In addition, the study will also investigate the safety, tolerability of a single-dose co-administration of LAE102 and LAE103 in healthy overweight/obese participants.

Full description

This is a randomized, double-blind study comprising of a single-dose escalation study in healthy overweight/obese participants (Part A), a single dose study in healthy postmenopausal women (Part B), and a multiple-dose escalation study in healthy overweight/obese participants (Part C), designed to evaluate the safety, tolerability, Pharmacokinetics (PK )and pharmacodynamics (PD) profiles of LAE103 administered alone.

In addition, the study will also investigate the safety, tolerability, and PK/PD profiles of a single-dose co-administration of LAE102 and LAE103 in healthy overweight/obese participants (Part D).

About 104 participants will be enrolled in 13 cohorts with each cohort including 8 participants randomized 6:2 study drug:Placebo.

Enrollment: 104 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: Accepts Healthy Volunteers
