Clinical Trial 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.

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 38 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 and 60 mg dose levels. Each cohort will have 2 participants receiving placebo.
