Tirzepatide for Weight Loss Intervention in Early-Stage Hormone Receptor Positive/HER2 Negative Breast Cancer

United States40 participantsStarted 2024-10-30

Plain-language summary

This clinical trial aims to evaluate the effectiveness of tirzepatide in achieving a 5% or more body weight reduction in patients undergoing adjuvant treatment for hormone receptor-positive, HER2-negative (HR+/Her2-) breast cancer. The study will also assess the safety and tolerability of tirzepatide, its feasibility based on discontinuation rates, and completion of treatment. Secondary objectives include evaluating 3-year invasive disease-free survival (IDFS) and distant relapse-free survival (DRFS), changes in BMI and body fat distribution, metabolic markers, and circulating tumor DNA (ctDNA).

Inclusion Criteria: * Consent: Be willing and able to provide written informed consent for the trial. * Age: Male or Female patients aged 18 years or older. * Breast Cancer Diagnosis: Have hormone receptor-positive (HR+), HER2-negative (HER2-) breast cancer previously diagnosed by biopsy. HR status is defined as estrogen receptor (ER) \>10% and/or progesterone receptor (PR) \>10%; HER2 status is defined as immunohistochemistry (IHC) 0 or 1+ or IHC 2+, fluorescence in situ hybridization (FISH) negative. * Stage: Have previously untreated early-stage, clinical or anatomic stage I, II, or III hormone receptor-positive breast cancer. * Definitive Treatment: Have had definitive treatment with curative intent for breast cancer, including surgery, chemotherapy, and radiotherapy as indicated. * Body Mass Index (BMI): Have a BMI of 30 kg/m² or more, or a BMI of 27 kg/m² or more with one weight-related complication (e.g., hypertension, type 2 diabetes, dyslipidemia, obstructive sleep apnea, or cardiovascular disease). * Performance Status: Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2. * Cardiac Function: Have a left ventricular ejection fraction (LVEF) of 50% or greater, or greater than the institution's lower limit of normal (LLN), as assessed by echocardiogram (ECHO) or multigated acquisition (MUGA) scan performed at screening. * Organ Function: Demonstrate adequate organ function in screening labs. * Tumor Specimens: Have archived biopsy or surgica…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
