CBER requests additional clarification on the following items:

  1. Regarding Studies CSLCT-NHF-05-11, CSLCT-NHF-05-13, and CSLCT-NHF-04-99, you provided local and systemic (fever, chills, and malaise) reactogenicity data in your paper submission and datasets. However, we could not locate in the paper submission or in the datasets the characterization of the degree of intensity, mild, moderate, or severe, for each study subject. Please provide a summary of the proportions of subjects with mild, moderate, or severe reactogenicity events and the characterization of reactogenicity data for each subject as mild, moderate, or severe, or indicate where the data is located in the BLA submission.
  2. Please provide your plans for the submission of your culture confirmation study, your pediatric immune response and safety study, and your immune response and safety study in an at-risk adult population.

Please clarify. In addition, was the year of production, or sequential number of lot for each strain encoded in the lot number?
