Conditions

Interventions

BIOLOGICAL

HER2 - primed Dendritic cells

Dendritic cell will be administered at ultra-sound guided injections. Participants will receive 8 intratumoral injections. These injections will be administered twice per week per week (given 3 days apart). Participants will receive alternating injections (3 days apart) of HER2-primed followed by HER3-primed DCs. Participants will be treated at the following dose levels: Dose level 1: HER2 - primed Dendritic cells dose 10-20 million Dose level 2: HER2 - primed Dendritic cells dose 30-50 million Dose level 3: HER2 - primed Dendritic cells dose 80-100 million

BIOLOGICAL
