简要总结

This trial is a single-center, randomized, double-blind, placebo-controlled, single ascending dose (SAD) Phase I clinical trial conducted in healthy Chinese adults to evaluate the safety, tolerability and PK profiles of a single subcutaneous administration of ACC085 injection in healthy Chinese adults.

This is a single ascending dose study planned to enroll participants into 5 dose groups [94.4 mg (periumbilical abdomen), 314.8 mg (periumbilical abdomen), 944.4 mg (periumbilical abdomen), 944.4 mg (lateral thigh), and a pending dose of X mg (periumbilical abdomen), which will be determined based on clinical progress]. Except for Dose Group 3, which plans to enroll 15 participants with a 4:1 ratio of participants receiving investigational product to placebo, all other dose groups will enroll 8 participants each with a 3:1 ratio of participants receiving investigational product to placebo. After all participants in Dose Group 1 complete the 4-week safety and tolerability assessment, if the dose-escalation stopping criteria have not been met, ACC085 will be escalated sequentially to Dose Groups 2-5 (314.8-944.4 mg and pending Dose Group X mg) with reference to the Fibonacci method and PK findings. Participant follow-up will continue until 48 weeks after dosing.
