On Friday afternoon, Marcus pulled the regulatory binder from the shelf to confirm everything was in order before Monday's planned enrollment visit. He worked through his pre-enrollment checklist methodically: IRB approval letter with current approval dates, signed investigator agreement, delegation log with all required signatures, training documentation for each team member.

Then he reached the section labeled "Regulatory Authority Documentation."

The IND number was listed on the protocol: IND 154832. But as Marcus flipped through the divider tabs, he found only a copy of the sponsor's original IND submission cover letter from eight months earlier. There was no FDA acknowledgment. No documentation that the IND was active. No safe-to-proceed letter.

Marcus felt his stomach drop. He had assumed the sponsor had filed all required documentation. But assumptions do not protect participants. Assumptions do not satisfy inspectors. And assumptions cannot be found in a regulatory binder.

He picked up the phone to call the sponsor's clinical operations manager. It was going to be a long weekend.
