Trial of Neratinib Plus Capecitabine in Subjects With HER2-Negative Metastatic Breast Cancer With Brain Metastases and Abnormally Active HER2 Signaling
Trial Parameters
Brief Summary
The purpose of this research is to look at the safety and effectiveness of a HER2-targeted therapy neratinib when given with capecitabine, a chemotherapy, for breast cancer patients with brain metastases whose tumors were HER2-negative by standard tests but showed abnormal HER2 activity based on the CELsignia results.
Eligibility Criteria
Inclusion Criteria: * Subjects must meet all of the following criteria to be enrolled: * Male/Female * At least 18 years of age * Histologically confirmed HER2 negative breast cancer determined from the most recent tumor sample (primary or metastatic), as per the current American Society of Clinical Oncology and College of American Pathologists HER2 testing guidelines. * For ER positive breast cancer patients: prior treatment with a CDK4/6 inhibitor and endocrine therapy in required in the metastatic settings. If a patient has received a CDK4/6 inhibitor plus endocrine therapy in the adjuvant settings and the cancer recurred while on the CDK4/6 inhibitor or within 12 months of the end of CDK4/6 inhibitor treatment, then the patient will eligible without getting a CDK4/6 inhibitor and endocrine therapy in the metastatic setting. * For triple negative breast cancer patients: no specific prior anti-cancer treatment is required. * Have radiological evidence of one or more brain metastases.
