Subject: STN 125363 - LRP Comments Item 13 Response
We have received feedback from the reviewers regarding Item 13 of the Lot Release Protocol Comments (sent to GSK on 3/20/2012).
We suggest that the ----(b)(4)----- Testing of TT be removed at the Purified TT stage and be added to the Purified and -----(b)(4)----- TT and the Purified and -------(b)(4)------- TT. We feel that this is important based on the following:
- This is an important safety test that confirms no reversion to active tetanus toxin.
- Purified TT can be stored for ------(b)(4)------ (still working on defining the expiry).
- It has been shown that –b(4)-- purification / -b(4)--------of TT has the potential for reversion to active tetanus toxin.
