NCT05327608

Brief Summary

This phase II trial studies whether time restricted eating (TRE) works to improve outcomes in patients with stage I-III breast cancer receiving chemotherapy before surgery (neoadjuvant) with a body mass index (BMI) 25-40. TRE 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. TRE may improve outcomes in patients with breast cancer.

Outcome Measures

Primary Outcomes (1)

  • Proportion of patients who can adhere to time restricted eating (TRE) >= 70% of days

    The proportion of patients that adhere to TRE will be estimated with the corresponding exact binomial 90% confidence interval.

    While undergoing neoadjuvant chemotherapy

Secondary Outcomes (7)

  • Pathologic complete response (pCR) rate

    Up to 4 months

  • Percent of patients who maintain or have a reduced body mass index and waist circumference

    Up to 4 months

  • Percent of patients who develop grade 3 or 4 toxicities

    Up to 4 months

  • Social determinants of health

    Up to 4 months

  • pCR rate among Non-Hispanic White patients

    Up to 4 months

  • +2 more secondary outcomes

Study Arms (1)

Treatment (TRE)

EXPERIMENTAL

Patients undergo TRE involving 16 hours of fasting and 8 hours of eating for 4 months while undergoing standard of care neoadjuvant chemotherapy. Patients also undergo blood sample collection on study.

  • Patients must have clinical stage I-III (utilizing tumor, node, metastasis \[TNM\] criterion) at diagnosis
  • Clinical T size must be \>= 1.5 cm if there is no radiographic or clinical evidence of axillary lymph node involvement. Any size tumor is allowed if axillary lymph nodes appear to be involved
  • Patient must be willing and able (have no contraindication) to receive recommended standard neoadjuvant therapy consisting of at least 16 weeks of planned neoadjuvant chemotherapy
  • Patients must have organ and marrow function adequate for initiating neoadjuvant chemotherapy as determined by their treating physician

  • Patient must have a personal email address, an internet-capable device, and the ability/ willingness to read and reply to email every day for the duration of the study

You may not qualify if:

  • Clinical T4 and/or N3 disease, including inflammatory breast cancer
  • Any prior treatment for the current breast cancer diagnosis, including surgery, chemotherapy, radiation, or experimental therapy
  • Women must not be pregnant or breast-feeding due to the potential harm to an unborn fetus and possible risk for adverse events in nursing infants with the treatment regimens being used. Patients must also not expect to conceive from the time of registration, while on study treatment, and until at least 6 months after the last study intervention
  • Patients with type 1 diabetes, or type 2 diabetes treated with insulin
  • Patients with a history of eating disorder
  • Patients who work on a rotating shift schedule
  • Patients must not have impaired decision-making capacity
  • Patients who are not English speaking as study staff is only able to provide the study intervention measurement tool
