What this study is testing

What is Ivonescimab?

Ivonescimab is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for metastatic colorectal cancer.

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 goal of this clinical research study is to learn if ivonescimab can help to control previously treated, metastatic colorectal cancer.
