A Master Protocol of Multiple Agents in Adults With Metabolic Dysfunction-Associated Steatotic Liver Disease (SYNERGY-Outcomes)
A Master Protocol for a Randomized, Controlled, Clinical Trial of Multiple Pharmacologic Agents in Adult Participants With Metabolic Dysfunction-Associated Steatotic Liver Disease Who Are at Increased Risk of Developing Major Adverse Liver Outcomes
In brief
The main purpose of the SYNERGY-OUTCOMES study is to find out whether retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in people with high-risk metabolic dysfunction-associated steatotic liver disease (MASLD). The study will enroll adults who have MASLD…

How this study is set up
The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

Trial stature
Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.
A strong methodological design for a phase 3 study, judged from its ClinicalTrials.gov record.

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.
How this score is built
- Investigator standing0/100
No investigator recorded in the registry for this trial
These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.
Summary
The main purpose of the SYNERGY-OUTCOMES study is to find out whether retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in people with high-risk metabolic dysfunction-associated steatotic liver disease (MASLD). The study will enroll adults who have MASLD based on non-invasive tests (NITs), which indicate they are more likely to develop MALO. Participants will be randomly assigned within a Master Protocol to receive either retatrutide (N1T-MC-RT01), tirzepatide (N1T-MC-TZ01) or placebo. The trial plans to enroll about 4,500 adults and will run for approximately 224 weeks. Participants may have up to approximately 25 to 30 clinic visits throughout the study to monitor their health, complete study procedures, and assess liver function and disease progression. Once the study is complete, eligible participants may participate in an optional 2-year extension study, in which all participants will receive either retatrutide or tirzepatide, even if they received placebo in the main study.
