If approved by the FDA, GSK's candidate vaccine would allow for completion of the rotavirus vaccination series by four months of age and could be integrated into the current vaccine schedule at the two and four month immunization visits. Severe rotavirus diarrhea and dehydration can occur as young as three months of age. Of children under five years of age in the U.S. hospitalized with rotavirus, approximately one in five are younger than six months of age. Rotavirus infects virtually every child in the US by age five and is the leading cause of severe gastroenteritis in infants and young children worldwide.
"We are delighted that Rotarix® has received a favorable recommendation by the Advisory Committee," said Una S. Ryan, Ph.D., President and Chief Executive Officer of AVANT Immunotherapeutics. "The FDA review marks a significant milestone towards the global commercialization of Rotarix®, which has already been approved for commercial use in over 100 countries worldwide, including the European Union."
About Rotarix®
Rotarix® is an oral, two-dose, live attenuated vaccine against rotavirus disease in infants. AVANT licensed the technology for Rotarix® to GSK in 1997 for worldwide commercialization. The vaccine was originally developed at Cincinnati Children's Hospital Medical Center. Rotarix® is the first human rotavirus vaccine derived from a human virus strain available in the market. The vaccine was developed to prevent rotavirus gastroenteritis by mimicking the protective effects of natural human rotavirus infection. Naturally occurring human rotavirus infection provides significant protection against subsequent moderate to severe rotavirus gastroenteritis regardless of the infecting serotype(s). Five Phase 3 clinical trials were conducted worldwide to assess the safety and efficacy of GSK's Rotarix® vaccine in support of U.S. licensure. The BLA for the GSK rotavirus candidate vaccine is based on one of the largest clinical development plans undertaken by a vaccine manufacturer and includes data from nearly 75,000 infants. The clinical trials conducted in support of U.S. licensure demonstrated efficacy against rotavirus gastroenteritis of any severity due to the five most common currently circulating rotavirus types. The most common solicited adverse reactions in clinical trials were fussiness/irritability, cough/runny nose, fever, loss of appetite, and vomiting.
