Joint submission of data by multiple registrants

E. Joint submission, opt-out

Under what circumstances can a registrant submit partially or fully separate data from other members of the joint submission?

Registrants must always submit their information within the framework of a joint submission. However, registrants can submit some information separately, if: 

  • it would be disproportionately costly for them to submit some information jointly, or
  • submitting the information jointly would lead to the disclosure of commercially sensitive information that would likely cause substantial commercial detriment, or
  • they disagree with the lead registrant on the selection of information.

Registrants who fall under any of the above circumstances can submit some or all data on their own: these are respectively called partial and full opt-out. Technical implementation of the opt-out is described in Q&A 396.
