This meeting was held to discuss the-----------------------(4)(4)------------------------------------------------------------developing and validating new assays for CTAB and polysorbate 80. ----------------------------------------------------------------------------------------------------------------------------------------------------(b)(4)---------------------------------------------------------------------------------------------------------------- validation package to support revised or new CTAB and P80 assays.

 

CBER stressed that the CTAB assay was a safety issue due to concerns with toxicity that has been associated with CTAB. As such, CBER believes it is important to implement a more sensitive CTAB assay as soon as possible. To assist, CBER offered to provide suggested alternative CTAB assays for Novartis’ consideration. In turn, Novartis accepted this offer, committed to working with Dr. Gupta’s lab on the development of these assays, and offered to provide progress reports.

 

Novartis stated that 3 months was not enough time to develop these assays and estimated that 6 months would be needed to develop properly validated assays and submit the reports to CBER.  CBER concurred.

 

Because of CBER concerns with CTAB cytotoxicity, ----------------(b)(4)------------------------------------------------------------------------- validated assays for CTAB and P80.
