简要总结
Overall design: The study will include one intervention based on Mediterranean diet plus structured lifestyle intervention (150 min/week of moderate-intensity or 75 min/week of high-intensity exercise) for a total of 16 weeks. Following a screening period of up to 12 months, eligible participants will be included in a single cohort.
Study details include:
- Study duration will be up to 36 months including the screening period.
- Intervention will be up to 16 weeks.
- Visit frequency will be every 4 weeks for the interventional period and every 12 weeks during follow-up.
详细描述
The UNMASK trial is a multicenter (Spain, Italy and Turkey), prospective, open-label lifestyle intervention based on tailored caloric restriction and monitored exercise. UNMASK aims to prove that the amelioration of MASLD at systemic and hepatic levels will be parallel to the improvement in our selected biomarkers. Given the known challenges with diagnosis and staging of MASH when using histopathological assessments of liver biopsies, the study will evaluate various blood-based non-invasive biomarkers. Non-invasive tests will be performed to asses endpoints. UNMASK includes a single arm in which patients undergo lifestyle changes, chiefly through the prescription of Mediterranean diet and physical exercise.
