Human Anti-Ipilimumab Antibody, clone AbD34428ia is a paratope specific, inhibitory anti-idiotypic antibody that specifically recognizes the monoclonal antibody ipilimumab. It does not recognize free human CTLA-4 (cytotoxic T-lymphocyte antigen-4) or ipilimumab in complex with CTLA-4.

Clone AbD34428ia is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a surrogate positive control or or reference standard in an anti-drug antibody (ADA) assay. This antibody has a monovalent intrinsic affinity of 0.3 nM, and is one of three antibodies with different affinities offered for ADA assays. Antibody HCA327 has affinity 16 nM and HCA329 has affinity 1 nM.

Ipilimumab (Yervoy) is a human IgG1/kappa antibody developed from a transgenic mouse. It has been approved by the FDA for the treatment of metastatic melanoma, renal cell carcinoma, and in combination with nivolumab for the treatment of previously treated microsatellite instability-high/deficient mismatch repair (MSI-H/dMMR) metastatic colorectal cancer. Ipilimumab activates the immune system by targeting CTLA-4, a protein receptor that downregulates the immune system. The action of cytotoxic T lymphocytes (CTLs) to recognize and destroy cancer cells is subject to an inhibitory mechanism that interrupts this destruction. Ipilimumab turns off this inhibitory mechanism and allows CTLs to function.
