What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to understand how different types of meals (meal macronutrients) affect blood fat levels, which is important for conditions like heart disease. Researchers are focusing on individuals with varying body fat levels and a kidney problem called nephrotic syndrome. Participants will consume meals with different nutrient balances during two clinic visits, and researchers will test their blood to observe the effects. Individuals with a health condition affecting fat metabolism or healthy volunteers might be suitable candidates. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group.

Do I have to stop taking my current medications for the trial?

The trial does not specify if you need to stop taking your current medications. However, if you are taking medications or supplements that might interfere with the study data, the investigator may ask you to stop.

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

Research has shown that different nutrients, such as fats, carbohydrates, and proteins, can affect blood fat levels. High-fat diets, particularly those rich in saturated fats, can raise cholesterol, a risk factor for heart disease. High-carbohydrate diets can also alter blood fat levels, but in different ways. This study examines how these nutrient differences impact individuals with varying body fat levels and kidney issues, such as nephrotic syndrome.

The trial investigates how the body processes meals with different nutrient levels. Testing involves simple procedures like blood tests and scans to measure body fat and metabolism, which are safe and routine.

The study is in an early phase, focusing on how well participants tolerate these meal variations. The information provided reports no serious side effects. Since these are regular meals with different nutrient focuses, they are likely to be well-tolerated by participants.12345

Why are researchers excited about this trial?

Researchers are excited about exploring meal macronutrients for managing blood fat levels because this approach focuses on dietary components rather than medication. Unlike standard treatments that often involve drugs like statins, which lower cholesterol by targeting enzyme activity in the liver, adjusting macronutrient intake aims to naturally influence blood fat levels through diet. This method could offer a more holistic and sustainable way to manage blood fat, potentially reducing the need for pharmaceuticals and their associated side effects. Additionally, the personalized nature of dietary interventions could cater to individual health needs, making it a promising area of study.

What evidence suggests that this trial's treatments could be effective for managing blood fat levels?

Research has shown that the nutrients in meals can significantly impact blood fat levels. Studies have found that diets with a moderate amount of fat reduce triglycerides (a type of fat in the blood) more effectively than low-fat diets. One study discovered that consuming high-quality nutrients, such as healthy fats and proteins, is linked to a lower risk of high blood fat levels. While low-carbohydrate diets can aid weight loss, they might also raise LDL (bad cholesterol) and total cholesterol levels. These findings suggest that balancing fats and carbohydrates in meals is crucial for managing blood fat levels, especially for individuals with health issues related to fat processing. Participants in this trial will explore how different meal macronutrient compositions affect blood fat levels.16789

Are You a Good Fit for This Trial?

This trial is for adults over 18 with conditions affecting body fat handling, like nephrotic syndrome or diabetes, and healthy individuals. Participants should have normal liver function tests, a BMI of at least 18.5 but less than 25 (or less than 23 for Asian descent), not drink excessively, and not be on interfering meds.

What Are the Treatments Tested in This Trial?

Interventions

  • Meal Macronutrients

Trial Overview

The study examines how high-fat, high-carbohydrate, and optionally high-protein breakfasts affect blood fat levels in participants with varying health statuses related to body fat. It involves overnight clinic stays with multiple blood draws after eating the meals to measure changes in lipid profiles.
