A Randomized, Multicenter, Placebo-controlled, Phase 3 Study to Evaluate the Efficacy and Safety of HER2/neu Peptide GLSI-100 (GP2 + GM-CSF) in HER2/neu Positive Subjects with Residual Disease or High-Risk PCR After Both Neoadjuvant and Postoperative Adjuvant Trastuzumab-based Therapy (FLAMINGO-01) (FLAMINGO-01)

This is a prospective, randomized, double-blinded, placebo-controlled, multi-center,
Phase 3 study of GLSI-100 immunotherapy in HLA-A*02 positive and HER2/neu positive
subjects who are at high risk for disease recurrence and have completed both neoadjuvant
and postoperative adjuvant standard of care therapy. Treatment consists of 6 intradermal
injections, Primary Immunization Series (PIS), over the first 6 months of treatment and 5
booster intradermal injections spaced 6 months apart. A third open-label arm will explore
GLSI-100 immunotherapy in non-HLA-A*02 positive and HER2/neu positive subjects.
