Survivorship Promotion In Reducing IGF-1 Trial

This is a prospective, single-center randomized trial with three arms, and an allocation ratio of 1:1:1. The study design is an efficacy study to evaluate the effect of metformin and coach-directed behavioral weight loss versus self-directed weight loss on insulin-like growth factor (IGF)-1 and IGF-1 to THE IGFBP-III ratio blood levels after 6 and 12 months of intervention. The coach-directed Behavioral Weight Loss arm is a web-based remote delivery and communication system that promotes healthy behavioral changes. The Metformin arm is a pharmaceutical intervention of oral metformin. This is a secondary prevention study for men and women who have survived solid malignant tumors

Treatment and study plan

metformin

Drug

Participants will receive metformin, an oral medication for type 2 diabetes.Participants randomized to the metformin intervention will receive metformin up to 2,000 mg per day.Dosing can be flexible, two or three times per day with meals as tolerated for 12 months.

Coach Directed Behavioral Weight Loss

Behavioral

Behavioral-based telephonic coaching with web-based support to promote healthy lifestyle and weight loss in overweight and obese adults.The goal of this intervention is to achieve at least 5% weight loss in the first six months of the intervention and maintain these improvements through month twelve by meeting dietary and exercise goals
