Obesity-related Mechanisms and Mortality in Breast Cancer Survivors

This objective of this randomized controlled trial is to conduct a 2x2 test of a lifestyle
intervention and metformin (a drug used to treat diabetes) to investigate how these
treatments, alone or in combination, affect biomarkers associated with breast cancer
survival. The Reach for Health Study will enroll 340 overweight/obese, postmenopausal breast
cancer survivors. After completing the screening process and baseline measures, participants
will be randomized in equal numbers to: (1) placebo, (2) metformin, (3) lifestyle
intervention and placebo, or (4) lifestyle intervention and metformin. The interventions
will last for 6 months. Concentrations of circulating biomarkers will be assessed at
baseline and 6 months.
