What this research studies

You would join a Phase II, multi-site trial enrolling about 30 people with Stage I–III invasive lobular breast cancer that carries a HER2 (ERBB2) mutation. Participants are randomized to receive either neratinib together with endocrine (hormone) therapy or endocrine therapy alone for an initial 4-week window, followed by a biopsy to check early tumor changes. Treatment continues up to surgery while doctors monitor tumor response, molecular changes, and side effects. The study is unblinded and led from Vanderbilt University Medical Center with other participating sites.

Who could benefit from this research

Good fit: Ideal candidates are people with Stage I–III, hormone receptor–positive invasive lobular breast cancer whose tumor testing shows a HER2 (ERBB2) mutation.

Not a fit: People without a HER2 mutation, those with HER2-amplified disease or non-lobular breast cancers, and patients unable to take neratinib or standard endocrine therapy are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the combination could shrink tumors before surgery and improve response and longer-term outcomes for people with HER2-mutant lobular breast cancer.

How similar studies have performed: Neratinib is FDA-approved in certain HER2-amplified early breast cancers and has shown activity with endocrine therapy in metastatic HER2-mutant breast cancer, but using neratinib before surgery in HER2-mutant lobular cancer is a newer approach.
