ONT-380 Has Stage IV HER2+ Breast Cancer Patient 'Worrying About Normal Stuff Again'

“Promising clinical trial results presented at the American Society for Clinical Oncology (ASCO) Annual Meeting 2015 show activity of the investigational anti-cancer agent ONT-380 against HER2+ breast cancer, in one case specifically against brain metastases and in another case in overall survival of heavily pretreated HER2+ breast cancer patients.

” ‘I am thrilled to have been able to offer this therapy to a patient in her early 40s. She didn’t have any other great treatment options that we would have expected to have any meaningful impact, especially on her brain. Now she’s been on the study over a year. The mets in her body are gone and the brain lesion has shrunk down to a little nubbin. She’s living a normal life, fretting about the family business and how the kids are doing – normal stuff,’ says Virginia Borges, MD, MMSc, director of the Breast Cancer Research Program and Young Women’s Breast Cancer Translational Program at the University of Colorado Cancer Center and one of the study’s authors.

“Both sets of results being presented are from ongoing phase 1b clinical trials of ONT-380, one in combination with the drug TDM-1, and the other in combination with capecitabine and/or trastuzumab. Women on these studies include those whose disease had progressed after at least two previous rounds of therapy (sometimes including previous drugs used to target HER2).”
