What is the purpose of this trial?

This trial tests a new treatment called LY3437943 (Retatrutide) to understand its behavior in the body, particularly its absorption into the bloodstream and duration of presence. Researchers compare results among individuals with varying liver function, from healthy to severely impaired. The trial also assesses the treatment's safety and tolerability. Ideal participants may have liver function issues but should not be expecting an organ transplant soon or require frequent medical procedures for their condition. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive it.

Do I need to stop my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators.

Is there any evidence suggesting that LY3437943 is likely to be safe for humans?

Research has shown that LY3437943, also known as retatrutide, is generally well-tolerated. In earlier studies, this treatment did not consistently affect liver function or other fat levels in the blood, suggesting it is safe for the liver. Specifically, one study found that 9 out of 10 patients with non-alcoholic fatty liver disease (NAFLD) had their liver fat levels return to normal after 48 weeks of treatment.

While these results are promising, LY3437943 remains in the early stages of testing for liver safety, so more information is needed to fully understand its safety. However, current evidence suggests it is a safe option for those considering joining a clinical trial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for liver function issues, which often focus on managing symptoms or slowing disease progression, LY3437943 offers a novel approach by potentially improving liver function directly. Researchers are excited about this treatment because it is administered subcutaneously, which could enhance patient compliance compared to oral or intravenous options. Additionally, LY3437943 is being studied for its effectiveness across different levels of hepatic impairment, from mild to severe, which could make it a versatile option for a broad range of patients. This unique feature sets it apart from traditional therapies that may not cater to varying degrees of liver function impairment.

What evidence suggests that LY3437943 might be an effective treatment for liver function?

Research has shown that LY3437943 may benefit liver health. Studies have found that it can reduce liver fat and enhance liver function. Specifically, it has reduced liver triglycerides (a type of fat) and lowered levels of alanine aminotransferase, an enzyme indicating liver health. These changes suggest that LY3437943 could aid individuals with liver issues. Early results also indicate it can assist with weight loss, which benefits liver conditions. Participants in this trial will receive LY3437943, with different arms assessing its effects on individuals with varying degrees of hepatic impairment. ^{1 2 3 4 6}

LY3437943 administered SC.

Group II: LY3437943 (Normal Hepatic Function) Experimental Treatment 1 Intervention

LY3437943 administered subcutaneously (SC).

Group III: LY3437943 (Moderate Hepatic Impairment) Experimental Treatment 1 Intervention

LY3437943 administered SC.

Group IV: LY3437943 (Mild Hepatic Impairment) Experimental Treatment 1 Intervention
