πŸ“… Updates on Approaches to Acceptable Intakes of Nitrosamine Drug Substance Related Impurities (NDSRIs) and Bioequivalence Assessment for Reformulated Drug Products(CRCG)

Date and Time:
November 6,
8:30 am – 5:30 pm,

November 7,
8:30 am– 5:30 pm

Co-hosts: FDA and the Center for Research on Complex Generics (CRCG)

In person (at The Universities at Shady Grove; Rockville, MD) and virtual workshop.

The purpose of this workshop is to review the current research and recommendations on methods for confirmatory testing of NDSRI formation, safety testing methods for NDSRIs and recommended acceptable intake limits for NDSRIs based on predicted carcinogenic potency and compound-specific data or read-across analysis. The workshop will also discuss strategies to mitigate the risk of NDSRIs formation. Another key focus of the workshop is to provide an update on FDA policy and guidance in assessing formulation stability, and recommendations for bioequivalence approaches when drug developers are considering reformulation.

Hi @Naiffer_Host ,
Thank you for sharing the registration link.
The event starts @ 6 pm IST and runs late night. Can we get the event recordings if we miss any of the presentations.

Dear @Naiffer_Host

Is there a possibility to get the slides from this event. I am attending a different Conference at the same time and therefore can not join this event, which is a pity.

Thanks for your help

Thank you for the information. I signed up today to attend the event virtually.
