Drug: Placebo
Registration Number
NCT06204250
Lead Sponsor
Changchun GeneScience Pharmaceutical Co., Ltd.
Brief Summary

The primary purpose of this study is to assess the safety and tolerability of single ascending doses of GS1-144 in healthy participants in Part 1 and to assess the safety and tolerability of multiple ascending doses of GS1-144 in healthy postmenopausal female participants in Part 2.

Detailed Description

This study will be divided into two sequential parts: Part 1 single ascending dose (SAD), and Part 2 multiple ascending dose (MAD) with the overall design.

Part 1 will enroll a total of approximately 46 healthy participants in five cohorts at 5 milligram (mg), 15 mg, 30 mg, 60 mg and 90 mg dose levels. Each cohort will have 2 participants receiving placebo. There is no restriction on the male-to female ratio.

Part 2 will be conducted after confirming the safety and tolerability of the -\>30mg dose in Part 1 and will enroll a total of approximately 30 healthy postmenopausal female participants and provisionally consists of three cohorts at 15 mg, 30 mg 60 mg and 120mg dose levels. Each cohort will have 2 participants receiving placebo.
