What registration information must I submit if my applicable clinical trial is required to be registered?

The regulations at 42 CFR 11.28 address which registration information requirements apply to which studies.

(81 FR 65121)
As outlined in the table, required registration information is determined by the study initiation date. The initiation date is the date on which the trial is initiated (i.e., the actual Study Start Date as defined in 42 CFR 11.10(b)(16). (81 FR 65120)
