Erika P. Hamilton, MD, associate director, Breast Cancer and Gynecologic Cancer Research Program, principal investigator, Sarah Cannon Research Institute, on ONT-380 for HER2-positive breast cancer and the treatment's ability to cross the blood-brain barrier. Hamilton says the reason ONT-380's ability to cross that barrier is important is because patients with HER2-positive breast cancer have a predilection to develop brain metastases.
She added that ONT-380 was proven to be effective when combined with capecitabine (Xeloda) and trastuzumab (Herceptin), though sometimes a combination of all three proved most useful. ONT-380 is a HER2-specific inhibitor and showed promising results when tested in patients with HER2-positive breast cancer who had previously received trastuzumab and T-DM1.
