Phase II Trial of Combination Immunotherapy With NeuVax and Trastuzumab in High-risk HER2+ Breast Cancer Patients
Summary
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.
