Brief summary: The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of LAE102 injection in healthy and overweight/obese participants, and also evaluate the preliminary pharmacodynamic effect of multiple dose injections in overweight/obese participants.

Detailed description: Part A is a randomized, double-blinded, placebo-controlled, single ascending dose by Intravenous (IV) administration in 40 Healthy participants;

Part B is a randomized, double-blinded, placebo-controlled, single ascending dose by subcutaneous (SC) administration in 24 Healthy participants;

Part C is a randomized, double-blind, placebo-controlled, multiple dose ascending and expanding by subcutaneous (SC) administration in 60 overweight/obese participants.
