Clinical trial for Colon Carcinoma
Official title Zanidatamab Before Surgery for the Treatment of HER2 Positive Colon and Rectal Cancer in Patients Planned for Curative Intent Treatment
ClinicalTrials.gov ID: NCT07405476
What this study is testing
What is Zanidatamab?
An investigational intravenous antibody being studied as a potential treatment for HER2-positive colon and rectal cancer before surgery. It is designed to bind to HER2 receptors on tumor cells.
Also referred to as ZW25.
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 giving zanidatamab before surgery helps treat HER2‑positive colon or rectal cancer.
- Who it's for
- It is looking for adults with stage I‑III colon or rectal cancer that tests positive for HER2.
- What's involved
- Participants will receive zanidatamab injections before their surgery and then have the usual surgical and follow‑up care.
- Time commitment
- The study lasts until the surgery and a short follow‑up period afterward, with a few clinic visits for drug administration and monitoring.
- Phase 2: a mid-size study of how well it works
- Time commitment: about 2 years
