Subject:                RE: Comment from Dr. Lev Sirota regarding the bioassay statistical review

Jack and Carmel,

    Dr. Lev Sirota completed his statistical review of the bioassays and there is one comment (see below) regarding any potential future validation assays.

  • In the Pneumococcal Enzyme-linked Immunosorbent Assays (PnELISAs) sub-section of section 5.3.1.4 “Analytical and Bioanalytical Methods” you used a criterion for linearity of R>(b)(4). This criterion appears to be too liberal. All presented linear regression data in this part of study demonstrate a coefficient of correlation of 0.99 and above. CBER recommends that you make criterion more stringent for future validations of the method. Please comment.

If you have any questions, please contact Julie or myself.

Thank you,

Mike
