Obesity and metabolic abnormalities accelerate decompensation in compensated cirrhosis, driven by clinically significant portal hypertension (CSPH, HVPG≥10 mmHg). Lifestyle-induced weight loss can lower portal pressure, but pharmacological options are limited. Mazdutide, a dual GLP-1/glucagon receptor agonist, has proven weight-loss and glycaemic benefits, yet its safety and efficacy in cirrhosis with portal hypertension are unknown. This investigator-initiated, single-arm, open-label, exploratory trial evaluates whether mazdutide can safely reduce portal pressure in overweight patients with compensated cirrhosis and CSPH.
The main questions it aims to answer are:
Does 16-week mazdutide treatment reduce HVPG (percentage change from baseline)? What adverse events occur, and is the drug tolerated?
Participants will:
Receive mazdutide SC injection once weekly for 16 weeks, titrated from 2 mg to 4 mg to 6 mg (if tolerated), with dose adjustment for intolerance.
Undergo HVPG at baseline and week 16 (primary endpoint). Have FibroScan® (liver/spleen stiffness, CAP) at baseline and weeks 4, 8, 12, 16.
Provide blood samples for liver, renal, glucose, lipid, and coagulation tests at each visit.
Undergo body composition, handgrip strength, and nutritional assessments to monitor muscle mass.
Attend clinic visits every 4 weeks during treatment and one follow-up visit 4 weeks post-treatment.
Key eligibility: Adults 18-75 with compensated cirrhosis (viral, MASLD, or alcohol-related), HVPG≥10 mmHg, BMI≥28 or ≥26 with comorbidities, stable weight, and stable carvedilol/propranolol if used. Exclude prior decompensation, HCC, CTP≥B8, eGFR\<60, mazdutide contraindications, active infection, uncontrolled hepatitis, portal vein thrombosis, etc.
Endpoints: Primary - % change in HVPG. Secondary - HVPG response (≥10% decrease or \<10 mmHg), decompensation events, treatment discontinuation due to AEs. Exploratory - changes in stiffness, liver fat, metabolic parameters, body composition, nutrition.
Safety: AEs (CTCAE v5.0), labs, vitals, with special monitoring for GI symptoms, dehydration, renal function, hepatic encephalopathy, muscle loss, pancreatitis, and gallbladder events.
Sample size and analysis: 50 patients. Primary endpoint analysed by paired t-test or Wilcoxon (α=0.05, two-sided) in FAS and PPS. Secondary endpoints mainly descriptive; key secondary tested for support. Subgroup analyses planned if feasible.
Study duration: 20 weeks (2-week screening, 16-week treatment, 4-week follow-up). Conducted at Second Affiliated Hospital of Chongqing Medical University, China. Ethics approved, informed consent required. This study will provide first evidence on mazdutide for portal hypertension in overweight cirrhosis.

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
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.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Drug: Mazdutide injection
Mazdutide injection is a sterile, clear to almost colorless liquid formulated for subcutaneous administration. It is supplied in three fixed-dose strengths for this study: 2 mg/0.5 mL, 4 mg/0.5 mL, and 6 mg/0.5 mL. Participants assigned to this arm receive once-weekly subcutaneous injections over a 16-week active treatment period. The regimen begins with a forced dose-titration phase: 2 mg weekly for the first 4 weeks, followed by 4 mg weekly for the next 4 weeks, and then 6 mg weekly for the final 8 weeks, provided the preceding dose is tolerated. In cases of treatment-emergent adverse events (CTCAE grade ≥2 or intolerable grade 1), the investigator may temporarily withhold the dose, step down to the next lower dose level (6 mg→4 mg→2 mg), or permanently discontinue the drug. After symptom resolution, gradual re-escalation (2 mg→4 mg→6 mg) may be attempted at the investigator's discretion.
Percentage Change in Hepatic Venous Pressure Gradient (HVPG) from Baseline
Percentage change in HVPG (measured in mmHg) from baseline to week 16. HVPG is calculated as the difference between wedged hepatic venous pressure (WHVP) and free hepatic venous pressure (FHVP), measured via hepatic vein catheterization under fasting conditions. A negative percentage change indicates a reduction in portal pressure. HVPG measurements will be performed in triplicate through the same hepatic vein, preferably in the morning, at baseline (screening period) and at week 16 (end-of-treatment visit, Day 112). All measurements follow a standardized procedure by experienced operators (≥25 HVPG measurements annually).
Time frame: Baseline (screening, Day -14 to -1) to Week 16 (End of Treatment, Day 112 ± 3 days)
Proportion of Participants Achieving HVPG Response
Proportion of participants with a reduction in HVPG of ≥10% from baseline, or a reduction to an absolute value of \<10 mmHg at week 16. HVPG is measured via hepatic vein catheterization in triplicate under fasting conditions.
Time frame: Baseline to Week 16 (End of Treatment, Day 112 ± 3 days)
Incidence of Hepatic Decompensation Events
Number of participants experiencing any first or recurrent decompensation event during the treatment period, including: overt ascites (requiring paracentesis or diuretic escalation), overt hepatic encephalopathy (West Haven grade ≥2), or gastroesophageal variceal bleeding (confirmed by endoscopy or imaging).
Time frame: Baseline up to Week 16 (End of Treatment)
Treatment Discontinuation Due to Adverse Events
Number of participants who permanently discontinue study drug due to any adverse event (AE) during the 16-week treatment period, regardless of causality. Reasons for discontinuation will be summarized by system organ class and preferred term.
