Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Take Off Pounds after Stroke (TOPS) trial is a Prospective Randomized Open-Label Blinded Endpoint (PROBE) study that will test a 12-week high protein, calorie restricted, partial meal replacement program, compared to enhanced standard care, for efficacy in achieving clinically significant weight loss without impairment of physical function patients with elevated body mass index (BMI) following a recent ischemic stroke.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The TOPS trial is designed as a PROBE study to test the feasibility, safety, and efficacy of a 12-week high protein, calorie restricted, partial meal replacement program, compared to enhanced standard care, in achieving clinically significant weight loss without impairment of physical function when initiated within 90 days following ischemic stroke in patients with BMI 27-to-49.9 kg/m2.

Participants will be randomized in a 1-1 ratio to the partial meal replacement program (diet intervention) or enhanced standard care (control) with randomization stratified by recruitment center (BIDMC, Yale) and baseline diet consistency status (Modified Consistency Diet vs Regular Consistency Diet). Baseline diet consistency status was selected as a stratification factor because it is expected that patients with difficulty swallowing (dysphagia) after stroke that results in need for modifications to food/liquids will have a different weight loss trajectory than patients who are able to safely consume a regular diet. The follow-up duration will be 12 weeks for all subjects.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Diet Intervention

The diet intervention is a partial meal replacement program using the commercially available OPTAVIA® Optimal Weight 4\&2\&1 Plan™. In the OPTAVIA program, subjects are asked to eat 6 times each day, once every 2 to 3 hours.

Group Type EXPERIMENTAL

Partial meal replacement program

Intervention Type BEHAVIORAL

Four meals consist of meal replacements made by OPTAVIA, such as shakes, soups, bars, biscuits, hot drinks, and puddings. Meal replacements will be provided to subjects without charge. For two other daily meals, subjects or their caregivers will be taught how to prepare meals consisting of 5-7 ounces (cooked) of a low-fat protein, 3 servings of non-starchy vegetables, and up to 2 servings of healthy fats.

Enhanced Standard Care

The control group will receive instruction on a healthy diet as defined by the United States Department of Agriculture.

Group Type PLACEBO_COMPARATOR

Dietary Counseling

Intervention Type BEHAVIORAL

Participants will receive one 45-minute counseling session on a healthy diet
