About this study

Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Phase 2a Clinical Study to Evaluate the Efficacy, Safety, and Pharmacokinetic Characteristics of Kylo-0603 Capsule in Study Participants With Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a metabolic stress-related liver injury closely associated with insulin resistance, with a global prevalence of approximately 25%. It may progress to metabolic dysfunction-associated steatohepatitis (MASH), which can lead to cirrhosis, end-stage liver disease, and increased cardiovascular risk, representing a major unmet medical need. Thyroid hormone receptor beta (THRβ) is predominantly expressed in the liver; selective agonism regulates hepatic lipid metabolism, reduces fat accumulation, suppresses hepatic inflammation and fibrosis, and may delay MASH progression. Kylo-0603 is a liver-targeted, highly selective THRβ agonist modified with GalNAc to enrich hepatic exposure and reduce peripheral effects. This multicenter, randomized, double-blind, placebo-controlled Phase 2a study will evaluate the efficacy, safety, and pharmacokinetics of once-daily oral Kylo-0603 capsules in approximately 120 participants with MASLD and overweight or obesity. Participants will be randomized 1:1:1:1 to Kylo-0603 8 mg, 12 mg, 16 mg, or placebo for 12 weeks. The primary endpoint is the percentage change from baseline in liver fat content assessed by MRI-PDFF at Week 12.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Kylo 0603 Capsule 8mg, Kylo 0603 Capsule 12mg and Kylo 0603 Capsule 16mg in people with Metabolic Dysfunction-Associated Steatoic Liver Disease, run by Shanghai Chia Tai Tianqing Pharmaceutical Technology Development 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 9 inclusion and 22 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: opening soon, as of the sponsor's last update on 16 Oct 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Lai Wei, Doctor (13601281862, weilai@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The percentage change from baseline in liver fat content (time frame: After 12 weeks of treatment.). 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 16 Oct 2026.
