Spots Global Cancer Trial Database for Intermittent Fasting for the Improvement of Outcomes in Patients With Stage I-III Breast Cancer Receiving Chemotherapy Before Surgery

Study Description

Brief Summary: This trial studies whether intermittent fasting works to improve outcomes in patients with stage I-III breast cancer receiving chemotherapy before surgery (neoadjuvant) with a body mass index \>= 25. Intermittent fasting has been shown to elicit similar metabolic changes as calorie restriction such as reduction in blood glucose levels, improved insulin sensitivity, and reduction of tumor cell growth. Intermittent fasting may improve outcomes in patients with breast cancer.

Detailed Description: PRIMARY OBJECTIVE: I. To evaluate the proportion of patients that can adhere to intermittent fasting (14:10) in patients with HER2 negative and estrogen receptor (ER)/progesterone receptor (PR) \< 10% breast cancer who receive neoadjuvant chemotherapy (NCT) for a new diagnosis of stage I-III breast cancer. SECONDARY OBJECTIVES: I. To evaluate the pathologic complete response (pCR) rate of intermittent fasting (14:10) in patients with HER2 negative and ER/PR \< 10% breast cancer who receive neoadjuvant chemotherapy (NCT) for a new diagnosis of stage I-III breast cancer. II. To evaluate the effect of intermittent fasting in the prevention of weight gain, measured by body mass index (BMI) and waist circumference, in patients who are undergoing neoadjuvant chemotherapy. III. To evaluate the differences in the pCR rate among breast cancer patients within different race/ethnic groups, African American versus (vs.) Non-Hispanic White (AA vs NHW) and based on baseline social determinants of health when undergoing NCT. IV. To evaluate if study intervention acceptability, adherence, and engagement differ by race (AA vs NHW) and based on baseline social determinants of health. V. To evaluate if percent of patients with Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade 3 or 4 toxicities differ by race (AA vs NHW) and based on baseline social determinants of health. EXPLORATORY OBJECTIVES: I. To monitor changes in the following inflammatory markers in patients undergoing neoadjuvant chemotherapy with intermittent fasting: fasting glucose, hemoglobin A1c, insulin, leptin, adiponectin, free fatty acids and lipids. II. To measure changes in markers involved in metabolic and lipogenic signaling pathways, immune modulation, and autophagy in adipocytes, tumor cells, and surrounding immune cells by Reverse-Phase Protein microarrays (RPPA) analysis. OUTLINE: Patients undergo intermittent fasting involving 14 hours of fasting and 10 hours of eating for 4 months while undergoing standard of care neoadjuvant chemotherapy. After completion of study treatment, patients are followed up for 6 months.
