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]
