Active clinical trials for "Rotavirus Infections"

Rotavirus (RV) is the most important cause of acute gastroenteritis (GE) requiring the hospitalization of infants and young children in developed and developing countries and can be a frequent cause of death in children less than 5 years of age (estimated nearly 500,000 annual deaths worldwide). GlaxoSmithKline (GSK) Biologicals has developed a vaccine against human rotavirus gastroenteritis. A new formulation of the vaccine, with an alternative buffer, was developed. This study will be conducted to evaluate the new formulation compared to the existing formulation of the HRV vaccine.

The aim of this study is to evaluate the reactogenicity, safety and immunogenicity of GSK Biologicals' human rotavirus (HRV) vaccine given concomitantly with routine vaccines including OPV in HIV positive infants. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

The purpose of this study is to assess immunogenicity and safety of Rotarix TM when administered in healthy Taiwanese infants (aged 6 to 12 weeks at the time of first vaccination) who received Hepatitis B immunoglobulin after birth.

To assess the efficacy, immune response and safety of the oral live attenuated HRV vaccine (Rotarix) in healthy infants approximately 2 months of age and previously uninfected with human rotavirus

The aim of this this study is to confirm absence of immune interference between HRV vaccine and routine infant vaccinations currently in use in the USA.

The purpose of this study is to assess the immunogenicity in terms of antibody response and the safety/reactogenicity in terms of solicited and unsolicited symptoms and serious adverse events following primary vaccination of Taiwanese infants with pneumococcal conjugate vaccine GSK 1024850A co-administered with a diphtheria, tetanus, acellular pertussis (DTPa)-combined vaccine and rotavirus vaccine in children during the first 6 months of life.

It has been observed that in children who get a severe rotavirus infection, subsequent infections cause either no symptoms or generally only mild or moderate diarrhea. This evidence is the basis for developing a vaccine since it suggests that the first infection immunizes the child against disease upon re-infection. It was found that neonatal avirulent strains 116E and I321 induce protective immunity and offer clinical protection for at least one year. Both these strains are well characterized and the safety studies have been done in animal models. These candidate vaccine strains have been evaluated for safety and immunogenicity in adults and children (2 to 12 years of age) by a randomized double blind placebo controlled trial in Cincinnati, USA. In India, the diversity of rotavirus strains is greater and there is greater prevalence of malnutrition and co-infection with other enteric pathogens. These vaccines have therefore, also been tested in India.

This study was designed to evaluate the safety of the investigational rotavirus vaccine and the efficacy to prevent rotavirus gastroenteritis.

The main objective of this study is to provide immunogenicity data for GSK Biologicals' HRV vaccine when co-administered with OPV or when given alone (HRV vaccine dose given 15 days after the OPV dose).
