About this study

Official title: A Single-Center, Randomized, Double-Blind, Placebo-Controlled, Phase I Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Single and Multiple Dose Escalations of ACT500 (Formerly Known as NM6606) in Chinese Healthy Adult Participants

This is a single-center, randomized, double-blind, placebo-controlled Phase I clinical study, divided into two parts. The first part is a single-dose escalation study (Part1,SAD study phase), and the second part is a multiple-dose escalation study (Part2,MAD study phase). It's aimed to evaluate the safety, tolerability, and pharmacokinetics (PK) of ACT500 in healthy adult participants, and to explore possible metabolites and biomarkers of ACT500.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ACT500 tablets in people with Non-alcoholic Steatohepatitis, run by Xiamen Amoytop Biotech 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 5 inclusion and 26 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 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?

Adverse Event(AE) (time frame: SAD:Day1-8; MAD:Day1-22.). The study lists 11 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 2026.
