Study summary

A phase 3, randomized, double-blind, placebo-controlled study evaluating the safety and tolerability of HSK31679 compared to placebo in patients with metabolic dysfunction-associated steatohepatitis (MASH) .

Read the detailed description

This study has 2 parts.Participants will be assigned to Part 1 based on screening histologic (liver biopsy) criteria or non-invasive test criteria. The purpose of the first part of this study is to find out the effect of HSK31679 on MASH and liver fibrosis. Participants will be assigned to Part 2 based on non-invasive test criteria.The purpose of the second part is to find out how safe HSK31679 is in improving liver function.

Eligibility criteria

Key Inclusion Criteria:

  • 1. Must be willing to participate in the study and provide written .

  • 2.MELD score ≥12 due to hepatic disease。
  • 3.Received medication therapy that may induce MAFLD/MASH for ≥ 2 weeks within 12 months prior to liver biopsy (including historical biopsy).
  • 4.Participants who had not been on stable medication with vitamin E (dose>400 IU/day) or polyunsaturated fatty acids or ursodeoxycholic acid within 6 months prior to liver biopsy (including historical biopsy); or had not been on stable medication with thiazolidinediones (TZD), sodium-glucose cotransporter 2 (SGLT2) inhibitors, or complex oral antidiabetic (OAD) regimens (≥3 OADs) within 3 months prior to liver biopsy (including historical biopsy).
  • 5.Participants who have undergone bariatric surgery (e.g., gastroplasty, Roux-en-Y gastric bypass, etc.) within 5 years prior to screening or plan to receive such surgery during the study.
  • 6. ≥ 8.0%.
  • 7.Chronic liver diseases other than NASH.
  • 8.Active disease. 9.Serum > 250 U/L. 10.Active, serious medical disease with a likely \< 2 years.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

What researchers measure

Primary outcomes

  1. Number of Participants With Resolution of Steatohepatitis Without Worsening of Fibrosis at Week 52.

    Resolution of steatohepatitis is defined as total absence of ballooning (score=0) and absent or mild inflammation (score 0 to 1). Worsening of fibrosis is defined as progression of fibrosis by ≥1 stage.

    Time frame: Week 52

  2. Number of Participants With at Least an Improvement of Fibrosis ≥1 Stage Without Worsening of Steatohepatitis at Week 52.

    Worsening of steatohepatitis is defined as increase in non-alcoholic fatty liver disease (NAFLD) Activity Score (NAS) for ballooning, inflammation, or steatosis.

    Time frame: Week 52

  3. Time to First Occurrence of Disease Progression

    Final analysis of the time to first occurrence of disease progression will be measured by a composite of protocol-specified clinical events

    Time frame: Up to 4.5 years

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2026 (actual). Primary completion is estimated for Jun 2029, 36 months after the start.

Of 34 phase 3 interventional studies under Non-alcoholic Fatty Liver Disease, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 61. This study's planned 36 months is close to that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 23, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
