`NDA 20-372/SE1-008,
`(b) (4)010 were linked together for purpose of review. The CMC
`15. Comments: NDA 2l-372/S-008,
`
`
`
`review will be attached to NDA 21—372/512'1-008, which proposes a new efficacy claim, namely the treatment of
`post-operative nausea and vomiting (PONV). The original NDA 21-372 was approved for use in the treatment
`
`
`of chemotherapy-induced nausea and vomiting (CINV). A CMC review is required for this supplement because
`the applicant is also proposing a new package presentation, designed to deliver a smaller dose for the PONV
`
`indication.
`
`
`(b) (4)
`
`
`The following CMC items are identical to those approved in original NDA 21-372:
`
`0 Drug substance manufacturer, method of manufacture, Specifications, and stability
`
`
`Drug product formulation, method of manufacture (including sterilization), and manufacturing facility
`
`
`Drug product specifications (with the exception of the numerical value for fill volume) and test facility
`
`
`Composition of container closure system
`(b) (4)
`
`
`Stability protocol
`
` The following CMC items are different for the new package presentation (21—372/S-008):
`
`-
`Package presentation (cohgirzig closure system size).
`0
`
`
`
`The application was consulted to the microbiology staff for review, and was found acceptable regarding sterility
`assurance (Review noted, no comments — NAI signed by Bryan Riley).
`
` 16. Conclusions and Recommendations: Recommend approval from the standpoint of CMC. Adequate
`
` information was provided regarding the new presentation of the drug product.
