Motavizumab (proposed INN, trade name Numax) is a humanized monoclonal antibody. It is being investigated by MedImmune (today a subsidiary of AstraZeneca) for the prevention of respiratory syncytial virus infection in high-risk infants. [1] As of September 2009, it is undergoing Phase II and III clinical trials. [2]

In June 2010, the FDA Antiviral Drugs Advisory Committee declined to endorse MedImmune's request for licensure of Motavizumab in a 14 to 3 decision. The members of that panel cited several reasons for the decision, and many were concerned that "we're not looking at a product that has evidence of superiority in terms of efficacy" when compared to the already available monoclonal antibody Palivizumab. [3]

In December 2010, AstraZeneca in a stock market statement stated that it would be writing down $445m (£286m) after discontinuing a key development programme for Motavizumab. The company stated that it would no longer develop Motavizumab for the prevention of respiratory syncytial virus (RSV), and as a result was withdrawing its licence application to the US Food and Drug Administration. It added that it would continue to develop Motavizumab for other treatments of RSV. [4]

Passive antibody therapy, also called serum therapy, is a subtype of passive immunotherapy that administers antibodies to target and kill pathogens or cancer cells. It is designed to draw support from foreign antibodies that are donated from a person, extracted from animals, or made in the laboratory to elicit an immune response instead of relying on the innate immune system to fight disease. It has a long history from the 18th century for treating infectious diseases and is now a common cancer treatment. The mechanism of actions include: antagonistic and agonistic reaction, complement-dependent cytotoxicity (CDC), and antibody-dependent cellular cytotoxicity (ADCC).

Clesrovimab (MK-1654) is a fully human monoclonal antibody designed to prevent respiratory syncytial virus (RSV) infections. Developed by Merck, it is in a phase III trial as of 2023. It works differently than nirsevimab.
