Obesity Clinical Trial
Official title:
SMARTer Weight Loss Management
The SMARTer trial will be a three-arm, randomized controlled non-inferiority trial that compares the optimized, adaptive SMARTer intervention, fixed DPP, and usual care assessment-only (Control). The trial will address whether a scalable, stepped-care intervention can stand up to gold-standard DPP by achieving comparable weight loss at a lower cost. Alongside evaluation of clinical non-inferiority, a comprehensive economic evaluation will inform relative affordability. Cost information is important to inform treatment policy and change standard of care, but is sorely lacking for behavioral interventions. The SMARTer intervention reduces costs by initially offering minimal intervention to all and stepping up to offer more costly treatment components only to non-responders who fail to attain the target weight loss. A rigorous economic evaluation planned and designed alongside the SMARTer trial will provide an accurate, robust head-to-head comparison of costs, cost-effectiveness, and projected lifetime health care costs between the three arms.
The proposed study seeks to test the hypothesis that SMARTer is non-inferior to DPP in its effect on 6-month weight loss. During the 24-week active intervention phase, participants will be randomized to one of three first-line treatments: 1) the adaptive SMARTer intervention, 2) fixed DPP, or 3) usual care assessment-only (control). Participants will be assessed at 3-month, 6-month, 9-month, and 12-month timepoints to evaluate overall weight loss, and to explore whether SMARTer is cost-effective compared to DPP or standard care. ;
