Phase 3 Data Regarding Anti-RSV Antibody To Be Presented at Pediatric Academic Societies (PAS) Annu...(requiring outpatient medical management ...),Health

The overall incidence and severity of adverse events (AEs) were similar between the motavizumab and the placebo groups in these Native American infants. The mortality rates were not statistically different between groups (0.4 percent in the placebo arm, n=2 and 0.3 percent in the motavizumab arm, n=3) and were not considered to be related to the study drug. As was suggested in the pivotal Phase 3 trial conducted in high-risk, preterm infants, rates of skin reactions were more common following Motavizumab than placebo (by an approximately 2 percent increase in frequency). Motavizumab was otherwise well tolerated.

About RSV

Each year, up to 125,000 infants in the U.S. are hospitalized with severe RSV infections, the leading cause of lower respiratory tract infections in infants in the United States. RSV is the most common respiratory infection in infancy or childhood. Approximately one-half of all infants are infected with RSV during the first year of life, and nearly all children have been infected at least once by the time they reach their second birthday. Children born prematurely as well as those with chronic lung disease (CLD) or congenital heart disease (CHD) are at highest risk for severe disease and hospitalization due to RSV. The virus may also cause severe illness in other high-risk groups such as the elderly, those with underlying respiratory or cardiac disease, and those with compromised immune systems (e.g., bone marrow transplant patients). Otherwise healthy infants in some Native American populations have demonstrated rates of RSV hospitalization that are similar to those among children with underlying medical conditions in the general U.S. population.

About Motavizumab

Motavizumab is an investigational humanized MAb being evaluated for its potential to prevent serious lower respiratory tract disease caused by RSV in pediatric patients at high risk of RSV
