Selected regulatory and scientific topics for candidate rotavirus vaccine development.
Various aspects of the development of rotavirus vaccine candidates are discussed. As is true with other vaccines, comprehensive testing must be done to detect the possible presence of adventitious agents in the vaccine and seed preparations. Consideration must also be given to other biologic materials that come in contact with the vaccine preparation during production to prevent the introduction of contaminants. The clinical testing of rotavirus vaccines from early safety and immunogenicity studies through final efficacy studies is also discussed. Issues surrounding coadministration of investigational rotavirus vaccines with US-licensed vaccines are ideally addressed before initiation of efficacy trials. Other subjects discussed are identification of correlates of protection, multivalent vaccines, foreign efficacy trials, safety data, and statistical considerations. Sponsors of investigational vaccines are urged to contact the Food and Drug Administration for guidance during the development process, especially before the investigational new drug application and pivotal efficacy trial stages.
