About this study

Official title: A Phase I Clinical Study of GS3-007a Dry Suspensions in Healthy Chinese Adults: Randomized, Double-Blind, Placebo-Controlled, Single- and Multiple-Dose, Dose-Escalation, and Food Effect Study

This study consists of two parts: the first part is a single-dose escalating(SAD) and food effect (FE)study, and the second part is a multiple-dose (14-day) escalating(MAD) study. Both phases are designed as randomized, double-blind, dose-escalation, placebo-controlled clinical studies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GS3-007a for SuspensionDrug

    GS3-007a dry suspension for oral use. Each sachet contains 50 mg of GS3-007a. The dry suspension is reconstituted with water before administration. Dosing is based on body weight, as specified in the arm descriptions. The product should be stored protected from light, in a sealed container, at or below 25°C.

  • Placebo GS3-007a for SuspensionDrug

    Placebo dry suspension matching GS3-007a in appearance, odor, and packaging. It contains all excipients except the active ingredient, with added bitter agent. It is reconstituted with water before administration. Dosing is based on body weight, as specified in the arm descriptions. Storage conditions are the same as for the active drug.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GS3-007a for Suspension in people with Healthy Adults, run by Changchun GeneScience Pharmaceutical Co., Ltd. at 1 site in China.

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 4 inclusion and 12 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 5 Nov 2026. 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 China. 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. Some participants in this study may receive a placebo. 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?

Number of Participants With Treatment Emergent Adverse Events (TEAEs) (time frame: up to 6 days (SAD+FE phase), up to 21 days (MAD)). 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 5 Nov 2026.
