Access Consortium New Active Substance (NAS) work-sharing initiative

Last updated

Access Consortium logo

The New Active Substance Work-Sharing Initiative (NASWSI) is an innovative work sharing procedure for the coordinated assessment of new chemical entity or new biological entity applications, or new indication applications that are submitted to two or more Access agencies.

By participating in this initiative, Access agencies are able to co-ordinate regulatory review procedures, and increase each agency’s capacity to ensure consumers have timely access to high quality, safe and effective therapeutic products.

For more information about work-sharing and its benefits for sponsors, see Australia-Canada-Singapore-Switzerland-United Kingdom (Access) Consortium.
