Dear Mike,

Please see draft comments below.  Please use these comments in preparation for our discussion scheduled for February 11th at 2 PM.  Thank you!

DRAFT COMMENT

Extractables and Leachables (E/L):
Background:
The primary container system for storage of the H5N1 antigen ----(b)(4)------------) is       --------(b)(4)---------------------- (approved for use in FluLaval seasonal influenza vaccines), the      --------(b)(4)--------------------------------------------. 
The final report containing the extractables and leachables data summarized in the submission for the ----(b)(4)------------------was provided in Amendment 26, February, 1, 2013.

            Regarding study ---------(b)(4)------------------ Extractables Analysis, ----(b)(4)------- was identified as the major extractable, and low amounts of --------------------------------------------------------------(b)(4)-------------------------------- were identified, within -----(b)(4)-----------------------------------------.  These extractable levels increased in water from ------(b)(4)-------- when stored at                    ------(b)(4)------. 

            The final report for a Controlled Extractables Study to compare the ------------------(b)(4)------------------------------ was also provided.

In this study, ---(b)(4)------ was detected in every sample extract and was the most abundant compound in each (b)(4) extract.  Its concentration was higher (3-5 fold) in the ----(b)(4)- extracts from ---(b)(4)------ compared to ---(b)(4)--.  Also the degradation product of          -------------------------------------------(b)(4)------------------------------------------------------------------- extract from the ---(b)(4)------- when compared to ---(b)(4)----.  In the ----(b)(4)------- analysis for the water solutions, ------------------(b)(4)--------------------------------- were detected in the ---------(b)(4)--.

Data on leachables were not provided for ---(b)(4)-----.

Reviewer’s comments:
You propose to store the H5N1 ---(b)(4)-------- for at least -(b)(4)- in these storage (b)(4).  Since the E/L studies for this ---(b)(4)---- are limited (only -----(b)(4)------------ and                    ----------(b)(4)------------------------), these data are insufficient to draw any conclusions about the appropriateness of these ---(b)(4)----- for ---(b)(4)--- for the proposed shelf life.

We have the following comment:
We recommend that the leachables studies be carried out in presence of the ---(b)(4)---------- for the length of the indicated shelf life.  Such studies can be part of the long term stability studies for the H5N1 (b)(4) in the --------(b)(4)----------.  These leachable studies using         ----(b)(4)----- should be compared with (b)(4) stored in the ---(b)(4)------- under similar conditions and storage times.  As an additional control, it is advisable to use newly filled          ------(b)(4)----------- with H5N1 antigen (b)(4) and/or monovalent seasonal influenza vaccine.
