Brief Summary
This phase 2 trial is a single-site sequential, multiple assignment, randomized trial (SMART) to test and construct a high-quality adaptive intervention of essential amino acids (EAA) and/or Low Sugar Diet for children with metabolic dysfunction associated steatotic liver disease (MASLD) and increased cardiometabolic risk. The basis for the trial includes high-quality pilot data in both EAA for hepatic steatosis and a low sugar diet for hepatic steatosis. In the trial, children aged 11-17 years old will be eligible to participate if their BMI is greater than or equal to 95th% at baseline and hepatic steatosis is greater than or equal to 8% at baseline by Magnetic Resonance Imaging Proton Density Fat Fraction (MRI-PDFF) because this is the most common age group diagnosed with metabolic-dysfunction associated steatotic liver disease.

Study Arms (2)
Essential Amino Acids Supplementation
ACTIVE COMPARATORThe essential amino acid supplement contains the following formulation: histidine, isoleucine, leucine, lysine, phenylalanine, threonine, and valine. EAA, also called AMS2392 has been shown to decrease hepatic steatosis and lower circulating very-low-density lipoprotein triglyceride (VLDL-TG) concentrations through one or more of the following mechanisms: decreasing de novo lipogenesis; increasing hepatic and systemic fatty acid oxidation; increasing triglyceride secretion from the liver in the form of VLDL-TG; and increasing clearance of circulating VLDL-TG via activation of lipoprotein lipase.
Low Sugar Diet
ACTIVE COMPARATORThe Low Sugar Diet uses the adapted and extended Social Cognitive Theory (SCT) guided low sugar intervention that the Emory team previously developed. The registered dietitian nutritionist (RDN) helps families to identify foods high in sugar and to identify acceptable replacements in order to remove foods and drinks high in free sugar from the home and replacement with low or no free sugar containing similar foods.

- Masking Details
- Due to the nature of the treatment, it is not realistic to blind the treatment to either staff or patients and their caregivers. To mitigate the risk of bias associated with an unblinded study, all study team members will remain blinded to aggregate study results and only select members of the study team responsible for interim monitoring will have access to these data
