ClinicalTrials.gov ID: NCT07229417
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 endocrine refractory.
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
- To learn if ivonescimab can help to control endocrine-refractory HR+ HER2- and/or TN mILC.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
