Summary

The study will be a multi-center, prospective, randomized, single-blinded, placebo-controlled Phase II trial of Herceptin + NeuVax(TM) vaccine (E75 peptide/granulocyte macrophage-colony stimulating factor) (GM-CSF) versus Herceptin + GM-CSF alone. The target study population is node-positive (NP) (or node-negative \[NN\] if negative for both ER and PR) breast cancer patients with HER2 1+ and 2+ expressing tumors who are disease-free after standard of care therapy. Disease-free subjects after standard of care multi-modality therapy will be screened and HLA-typed. E75 is a CD8-eliciting peptide vaccine that was restricted to HLA-A2+ or HLA-A3+ patients (approximately two-thirds of the US population), and has been extended to HLA-A24+ and HLA-A26+ as well.

Conditions

Interventions

DRUG

Herceptin

Herceptin will be administered to patients every three weeks as monotherapy for one year, to be given upon completion of standard of care chemotherapy/radiotherapy. The first Herceptin infusion will be given no sooner than three weeks and no later than 12 weeks after completion of chemotherapy/radiotherapy. Herceptin will be dosed at the recommended initial loading dose of 8 mg/kg and at recommended maintenance doses of 6 mg/kg q3wk.

DRUG

NeuVax vaccine

At the time of vaccine administration, a frozen solution of E75 acetate (1.5mg/ml) is thawed and 1000mcg E75 peptide mixed thoroughly with 250mcg GM-CSF. This constitutes the NeuVax vaccine. For patients randomized to the Herceptin + NeuVax vaccine arm, they will commence Herceptin monotherapy and then will begin the NeuVax vaccine series immediately after completion of the third Herceptin infusion. The vaccine series consists of NeuVax vaccine administered intradermally every three weeks for six total vaccinations, 30-120 minutes after completion of Herceptin infusion.

DRUG

GM-CSF

For patients randomized to the Herceptin + GM-CSF only arm, they will commence Herceptin monotherapy and then will begin the GM-CSF inoculation series immediately after completion of the third Herceptin infusion. The GM-CSF inoculation series consists of 250mcg GM-CSF administered intradermally every three weeks for six total vaccinations, 30-120 minutes after completion of Herceptin infusion.
