Background

Pembrolizumab is a highly selective IgG4-kappa humanized monoclonal antibody against PD-1 receptors. It was generated by grafting the variable sequences of a very high-affinity mouse antihuman PD-1 antibody onto a human IgG4-kappa isotype containing a stabilizing S228P Fc mutation. It contains 32 cysteine residues and the complete folded molecule includes 4 disulfide linkages as interchain bonds and 23 interchain bonds. It was developed by Merck & Co and first approved for the treatment of metastatic malignant melanoma by the FDA on September 4, 2014, becoming the first approved therapy against PD-1. In the time since its initial approval, pembrolizumab has been granted approval in the treatment of a wide variety of cancers.

Indication

Pembrolizumab is indicated for the following conditions:

For all approved adult indications, pembrolizumab may be used for an additional 6 weeks at 400mg weekly.
