Phase II Trial of Combination Immunotherapy With Nelipepimut-S + GM-CSF (NeuVax™) and Trastuzumab in High-risk HER2+ Breast Cancer Patients (HER3+)
This will be a multi-center, prospective, randomized, single-blinded, placebo-controlled phase II trial of trastuzumab + nelipepimut-S/GM-CSF versus trastuzumab + GM-CSF alone. Our target study population is high-risk HER2-positive breast cancer patients. High-risk HER2-positive breast cancer patients are defined as: Those with HER2-positive breast cancer, regardless of hormone receptor status, who receive neoadjuvant therapy with an approved regimen that includes trastuzumab and at least four cycles (12 weeks) of taxane-containing chemotherapy, and fail to achieve a pCR. Those with HER2-positive breast cancer, regardless of hormone receptor status, who undergo surgery as a first intervention and are found to have ≥ 4 positive lymph nodes. Those with HER2-positive, hormone receptor negative breast cancer who undergo surgery as a first intervention and are found to have 1-3 positive lymph nodes. Disease-free subjects after standard of care multi-modality therapy will be screened and HLA-typed.

Primary outcomes
- Invasive Disease-free Survival (DFS) — Initiation of trastuzumab monotherapy through the end of the patient's fifth year of participation in the study.
Compare invasive DFS between the two treatment groups from time of initiation of trastuzumab maintenance therapy (trasuzumab monotherapy) to time of invasive local, regional or distant recurrence, new primary, or death due to any cause. Disease state will be determined by the patients' own physicians at the individual study sites during their routine follow-up screening. This will occur for all enrolled patients, regardless of randomization, approximately every three months for the first 24 months after completion of primary therapies and every six months thereafter with clinical exam, and laboratory and radiographic surveillance. The primary outcome measure of the trial is invasive DFS.
