An off-the-shelf preparation of natural killer (NK) cells conjugated to a monoclonal antibody targeting human epidermal growth factor receptor 2 (EGFR2; HER2; ErbB2), with potential antineoplastic activity. Upon administration of anti-HER2 antibody conjugated natural killer cells ACE1702, the antibody moiety targets and binds to HER2 on tumor cells, which may lead to cell lysis of HER2-expressing tumor cells by the NK cells. HER2, a tyrosine kinase receptor, is overexpressed by many cancer cell types.
