Hormone Receptor-Positive Breast Cancer study: Tirzepatide
Official title Tirzepatide for Weight Loss Intervention in Early-Stage Hormone Receptor Positive/HER2 Negative Breast Cancer
ClinicalTrials.gov ID: NCT06518837
What this study is testing
What is Tirzepatide?
an investigational once‑weekly injectable medicine being studied for weight loss in patients with early‑stage hormone receptor‑positive, HER2‑negative breast cancer. is designed to activate both GIP and GLP‑1 receptors, which can help regulate appetite and metabolism.
Also referred to as LY3298176, Mounjaro, Zepbound.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see if tirzepatide can cause at least a 5% drop in body weight and be safe while patients receive standard breast cancer treatment. It will also look at longer‑term cancer outcomes and changes in body composition.
- Who it's for
- Adults with early‑stage hormone‑receptor‑positive, HER2‑negative breast cancer who are currently on adjuvant therapy.
- What's involved
- Participants will receive tirzepatide injections and attend regular clinic visits for weight checks, safety labs, and other routine tests. Blood samples may be taken to study metabolic markers and tumor DNA.
- Time commitment
- The trial runs for about three years with monthly dosing visits and periodic follow‑up appointments.
- Phase 2: a mid-size study of how well it works
