New Dual-Action drug aims to tackle fatty liver where semaglutide falls short
NCT ID NCT07713992
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This study tests whether switching to a new drug called mazdutide can reduce liver fat more effectively than staying on semaglutide in people with type 2 diabetes and moderate-to-severe fatty liver. Participants who have been on semaglutide for at least 16 weeks are randomly assigned to either switch to mazdutide or continue semaglutide. The main goal is to measure changes in liver fat using MRI and ultrasound.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a dual GLP-1/glucagon receptor agonist called mazdutide
- What this could lead to
- If successful, this could offer a new treatment option for people with type 2 diabetes and fatty liver who do not get enough benefit from semaglutide alone.
- What could go wrong
- This is a relatively small, early-stage trial. The results may not apply to all patients, and mazdutide may cause side effects like nausea or gastrointestinal issues.

Inclusion Criteria: * Aged between 18 and 60 years (inclusive) at the time of informed consent signing. * Diagnosed with type 2 diabetes mellitus. * Received once-weekly semaglutide 1.0 mg treatment for at least 16 consecutive weeks verified by medication records. * Diagnosed with moderate-to-severe fatty liver, defined as hepatic attenuation ≥269 dB/m by transient elastography and hepatic fat fraction \>10% measured by MRI-PDFF. * HbA1c level \<7%. * Body mass index (BMI) ≥24 kg/m². * Glycemic and weight management regimens without adjustments within 3 months prior to screening. * Voluntarily signed written informed consent and agreed to comply with the study protocol. Exclusion Criteria: * History of alcoholic fatty liver, drug-induced fatty liver, viral hepatitis, autoimmune diseases, or acute gallbladder diseases. * Use of medications affecting fatty liver metabolism within 3 months prior to screening, including but not limited to SGLT-2 inhibitors, vitamin E, GLP-1R/GIPR agonists, liver-selective thyroid receptor β agonists, PPAR agonists, and aspirin. * Use of weight-loss drugs or alternative weight-loss therapies within 3 months prior to screening. * Addition to sulfonylureas, glinides, dorzagliatin, or various insulin preparations within 3 months prior to screening. * History of bariatric surgery or planned bariatric surgery during the study (excluding acupuncture, liposuction and abdominal liposuction performed more than 1 year before screening). * Diagnosed with type 1 diabetes or latent autoimmune diabetes in adults. * Personal history of acute or chronic pancreatitis, personal or family history of medullary thyroid carcinoma (MTC), or family history of multiple endocrine neoplasia type 2 (MEN2). * Presence of severe cardiovascular, cerebrovascular, hepatic or renal insufficiency, uncontrolled diabetes, malignancy, cirrhosis or advanced liver fibrosis. * Pregnant or lactating females, those planning pregnancy within half a year, or with recent major surgery or severe infection. * Mental disorders or cognitive disorders that may interfere with study compliance, or any other conditions judged inappropriate for study participation by the investigator. * Contraindications to MRI examination, including implantation of pacemakers, metallic heart valves, magnetic surgical clips, implantable electronic infusion pumps, severe claustrophobia, or inability to tolerate MRI scanning.
