NEOBREADS: Neoadjuvant Breast Diet Study
Stopped early · Phase 1
Conditions studied: Breast Cancer
In brief
This is a feasibility trial of a 6-month extreme carbohydrate restricted diet (20 grams total carbs/day) via counseling with dietitian plus aromatase inhibitor therapy. Visits will occur at screening, mid-study, and pre-surgery. Anthropomorphic measurements, and patient reported outcomes (PROs) will be taken at all three visits. Patients will speak with a dietitian at their monthly standard of care visits, and will receive weekly calls for the first 4 weeks of the intervention. All subjects will receive surgery after approximately 6 months of intervention. Total duration of the study is expected to be 2 years, though each patient's participation will be approximately 6 months.
