About this study

Official title: A Phase 1 Clinical Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single and Multiple Ascending Doses of GS1-144 Tablets

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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GS1-144 in people with Vasomotor Symptoms and Adult Healthy Volunteers, run by Changchun GeneScience Pharmaceutical Co., Ltd. at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1: Number of Participants With Treatment -Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) (time frame: Up to Day 4). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2025.
