Pediatric Development Plan for IC51 (JE-PIV):

  • Appropriateness of the clinical studies suggested to support the pediatric licensure apart from the issues mentioned in the 7/25/08 email.
  • Appropriateness of age group stratification proposed by Intercell in a fax to FDA dated July 25, 2008.

Follow-up information requested in an e-mail on August 14, 2008 from Paul Wilson by Richard Daemer:

To follow up in the next few days, please provide us with a brief written summary of the information you have gathered to date regarding the feasibility of these studies in particular pediatric subpopulations. Please include the name of the organization and individual contacted and a brief summary of the advice/guidance given. We prefer that you wait until you have had a chance to make these inquiries at the U.S. State Department, the Centers for Disease Control, and perhaps at the corresponding organizations in some European countries.

This information will be helpful in formulating a reasonable and effective pediatric plan that meets the requirements of the Pediatric Research Equity Act (PREA). Please let us know if you have any further comments or information leading up to the Pediatric Review Committee meeting on August 27, 2008.

Also regarding the PVP please provide the justification for the sample size of 10,000 subjects. In general we would like to see at least a 20,000 subject post-marketing general safety study. If the vaccine is to be used in elderly individuals please provide safety data for this age group. The post marketing study may need to be tiered to include a certain number of individuals who are 70-79 and 80 or older.
