Take Off Pounds After Stroke Trial (TOPS)

Phase 2

Completed

• Conditions: Hemiparesis; Obesity; Overweight; Stroke
• Interventions: Behavioral: Dietary Counseling; Behavioral: Partial meal replacement program

• Registration Number: NCT03815214
• Lead Sponsor: Beth Israel Deaconess Medical Center

Brief Summary

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

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.

Arm && Interventions

Group	Intervention	Description
Enhanced Standard Care	Dietary Counseling	The control group will receive instruction on a healthy diet as defined by the United States Department of Agriculture.
Diet Intervention	Partial meal replacement program	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.

Primary Outcome Measures
