What is the purpose of this trial?

This trial explores two approaches for treating fatty liver disease: lifestyle changes alone or lifestyle changes combined with Vertical Sleeve Gastrectomy (VSG). The main goal is to determine which method more effectively reduces liver issues over 12 months. The trial seeks participants with fatty liver disease, possibly accompanied by type 2 diabetes or prediabetes, and a body mass index (BMI) between 35 and 60. Participants must be willing to follow a diet and exercise plan and may also need to undergo surgery. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could shape future treatments for fatty liver disease.

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

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

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown that vertical sleeve gastrectomy (VSG) is generally safe for people with obesity. Research indicates that VSG can significantly improve liver issues like scarring and fat buildup in about 60% of patients. This surgery is also associated with lower risks of major heart problems and death. However, the safety of weight-loss surgery, such as VSG, for people with liver disease remains not fully understood. Most reports focus on the first 30 days after surgery, so researchers continue to study long-term safety. For those considering participation in a trial involving VSG, this data suggests it is generally well-tolerated. It is always best to discuss the risks and benefits with a doctor. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about combining Vertical Sleeve Gastrectomy (VSG) with Lifestyle Modification Counseling for treating fatty liver disease because this approach targets weight loss in two powerful ways. VSG involves surgically reducing stomach size, leading to rapid weight loss without strict calorie limits initially, which is a fresh take compared to standard lifestyle changes alone. Meanwhile, the Lifestyle Modification Counseling offers a structured plan to change eating and exercise habits, modeled after the successful LookAHEAD trial. This dual strategy not only promotes significant weight loss but also aims to improve liver health more effectively than current treatments that rely solely on diet and exercise adjustments.

What evidence suggests that this trial's treatments could be effective for fatty liver disease?

Research has shown that Vertical Sleeve Gastrectomy (VSG), one of the treatments in this trial, can effectively treat fatty liver disease. Studies have found that VSG can reduce liver fat and improve liver health for many individuals. In one study, most patients experienced reduced fat buildup and inflammation in the liver, with 30% also seeing reduced liver scarring. Additionally, previous trials, such as the LookAHEAD study, demonstrated that weight loss through diet and exercise, part of the Lifestyle Modification Counseling arm in this trial, can enhance liver health by decreasing fat and inflammation. Both VSG and lifestyle changes, as separate treatment arms in this trial, have shown promising results for improving fatty liver disease. ^{6 7 8 9 10}

What Are the Treatments Tested in This Trial?

Interventions

• Lifestyle Modification Counseling
• Vertical Sleeve Gastrectomy

Trial Overview The study compares lifestyle modification alone versus vertical sleeve gastrectomy (VSG) combined with lifestyle changes over 12 months to see which better reduces liver damage in NASH patients. It aims to recruit and retain participants for invasive/non-invasive measurements and assess the safety of VSG.

How Is the Trial Designed?

Group I: VSG + LSM Experimental Treatment 2 Interventions

Procedure/Surgery: Vertical Sleeve Gastrectomy will be performed using five laparoscopic ports. The short gastric and epiploic vessels will be taken down With a 40 French Bougie in place, the greater curvature will be excised starting 6 cm proximal to the pylorus. Behavioral: Lifestyle Modification Counseling - The intensive lifestyle intervention will align with methods listed in the LSM arm description. However, participants assigned to the VSG will not have calorie ceilings during the first 6 months of rapid weight loss, and they will receive additional instruction regarding food volume and adequate protein intake.

Group II: LSM Active Control 1 Intervention

Behavioral: Lifestyle Modification Counseling - The intensive lifestyle intervention is modeled after the LookAHEAD trial, with modules modified for participants undergoing surgery, and designed to produce maximum achievable weight loss. Both groups will increase their level of moderate-intensity physical activity (such as walking) to a total of 325 minutes per week. All lifestyle-medical management participants will be given calorie intake targets of 1200, 1500, or 1800 kilocalories per day, depending on body weight, with the goal of producing a weight loss of 1 to 2 pounds per week. There will be 24 weekly counseling meetings during the first 6 months, bi-weekly meetings between months 7 and 9, and monthly meetings between months 10 and 12.

There is a growing need for better care pathways for patients at risk of advanced stages of non-alcoholic fatty liver disease (NAFLD), particularly in distinguishing between progressive fibrotic NAFLD and simple steatosis.

Implementing interdisciplinary care approaches will improve patient identification for necessary surveillance and treatment, while also enhancing understanding of NAFLD's relationship with lifestyle, genetics, and related health conditions.

In a 2-year study of 66 adolescents and young adults undergoing vertical sleeve gastrectomy (VSG), patients experienced significant weight loss of 25.3%, but also a concerning 8.5% decline in total hip bone mineral density (BMD), indicating potential negative effects on bone health.

The study found that VSG led to a decrease in volumetric BMD at the distal radius and tibia, primarily due to loss of trabecular bone, which may increase the risk of skeletal fragility in this population.

The review analyzed seven trials involving 373 participants to assess the effects of weight reduction strategies, including lifestyle changes and the drug orlistat, on non-alcoholic fatty liver disease (NAFLD), but found insufficient data to draw strong conclusions due to high risk of bias.

There is a need for more rigorous randomized clinical trials with low risk of bias to better understand the benefits and harms of weight reduction in NAFLD patients, particularly regarding long-term outcomes like fibrosis and quality of life.
