A Phase 2 Single-blinded Randomized Study of Algorithm-based Personalized Nutrition Intervention Compared to Standard Diet Intervention in Patients Treated With Endocrine Therapy for Early Stage, Hormone Receptor Positive Breast Cancer
The Breast Cancer Personalized Nutrition (BREACPNT) study will evaluate the effect of a microbiome based personalized diet intervention on control of weight gain, glycemic response, disease outcome and various biomarkers in hormone receptor early breast cancer patients receiving adjuvant endocrine treatment.
• Patients diagnosed with stage 1-3 breast cancer, who underwent surgery, have finished their neo/adjuvant chemotherapy and radiotherapy if these were indicated and are treated with adjuvant endocrine therapy (either Tamoxifen or Aromatase inhibitor +/- GNRH agonists).
• Patients are at least 60 days after finishing their last non-endocrine oncology treatment (i.e. definitive surgery, radiation or chemotherapy - whichever is last), have received at least 30 days of endocrine therapy ( tamoxifen or aromatase inhibitor) but no more than 24 months.
• Patients treated with neoadjuvant endocrine therapy are eligible provided they had undergone surgery, are least 60 days post their last non endocrine therapy (definitive surgery or radiation and chemotherapy, if these were indicated), are continuing their endocrine therapy but did not receive more than 24 months post-surgery.
