Taplitumomab paptox

Taplitumomab paptox (pronunciation: tap-li-tu-mo-mab pap-tox) is a monoclonal antibody designed for the treatment of cancer. It was developed by GlaxoSmithKline and is also known by its developmental code name, GSK2618960.

Etymology

The name Taplitumomab paptox is derived from the International Nonproprietary Naming (INN) system for pharmaceutical substances. The prefix "Tapli-" is used for monoclonal antibodies targeting tumor cells, "-tumomab" indicates that it is a murine (mouse) monoclonal antibody, and "paptox" signifies that it is conjugated with a bacterial toxin.

Mechanism of Action

Taplitumomab paptox is a monoclonal antibody that targets the CD22 antigen, a protein found on the surface of B cells. The "paptox" part of the drug is a bacterial toxin that is conjugated to the antibody. Once the antibody binds to the CD22 antigen, the toxin is internalized by the cell, leading to cell death.

Clinical Trials

Taplitumomab paptox has been studied in clinical trials for the treatment of Non-Hodgkin lymphoma and other B-cell malignancies. However, as of 2021, it has not been approved for use by any regulatory authority.
