The Ying and Yang – CRLs vs IRs ECDs and Approvals
Complete Response Letters (CRLs) (remember those letters where FDA was going to respond all at once with Division level review and you were not going to get any more discipline specific letters?) are a harbinger of “approval issues that are too great to resolve through other means”. Yes, that’s right, expect a CRL if issues are complex or too vexing to permit approval.
