Ampligen w/Vaccine Therapy for Stage II-IV HER2-Positive Breast Cancer (7425)
Phase I-II Study of HER2 Vaccination with poly(I) poly(C12U) (Ampligen®) as an Adjuvant in Optimally Treated Breast Cancer Patients
Status Conditions Phase Study ID
Closed Breast Cancer Phase I/II 7425/133

This randomized phase I/II trial studies the side effects and best dose of Ampligen when given together with vaccine therapy and sargramostim (GM-CSF) to see how well it works in treating patients with stage II-IV human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Vaccines made from synthetic HER2/neu peptides may help the body build an effective immune response to kill tumor cells.
