Good news from FDA! On 25 July 2016, FDA announced that CROs and consultants are no longer required to register separate ESG accounts for each client. You are now only required to have one ESG account for submissions for all clients.
This policy change is the latest of several recent improvements to the ESG, and the most welcome for many of us. Prior to this announcement, FDA required a CRO or consultant to create and use separate ESG accounts for each client. Most people considered this practice a tedious burden,without a clear benefit for industry or FDA.
You can find more information on the announcement at the ESG website.
