Trial of Neratinib Plus Capecitabine in Subjects With HER2-Negative Metastatic Breast Cancer With Brain Metastases and Abnormally Active HER2 Signaling

Is NCT04965064 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies Capecitabine and Neratinib. for breast cancer.

Phase 2RecruitingUniversity of RochesterNCT04965064Data as of May 2026

Treatment: Capecitabine and Neratinib.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.

Extracted eligibility criteria

Cancer type

Breast Carcinoma

Biomarker criteria

Required: HER2 (ERBB2) wild-type

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.

Required: HER2 (ERBB2) abnormally active signaling

Abnormally active HER2 signaling as determined by the CELsignia test on the tumor tissue.

Disease stage

Metastatic disease required

Performance status

ECOG 0–2(Ambulatory, capable of self-care)

Prior therapy

Must have received: CDK4/6 inhibitor — metastatic

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.

Must have received: endocrine therapy — metastatic

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 the CDK4/6 inhibitor treatment, then the patient will eligible without getting a CDK4/6 inhibitor and endocrine therapy in the metastatic setting.

Cannot have received: capecitabine (capecitabine)

Exception: capecitabine only in the perioperative setting for the primary early-stage breast cancer AND the breast cancer did NOT recur while taking capecitabine or within 180 days of the last dose of capecitabine therapy

Patients who have received capecitabine for the treatment of the current breast cancer in the metastatic setting; Patients who have received capecitabine only in the perioperative setting for the primary early-stage breast cancer AND the breast cancer recurred while taking capecitabine or within 180 days of the last dose of capecitabine therapy.
