Pre-submission strategy
Given the 180-day timeline and high cost of a PMA, pre-submission interaction with FDA is critical:
- Early Q-submission — discuss overall PMA strategy, clinical study design, endpoints
- IDE application — must be approved before beginning pivotal clinical trial
- Pre-PMA meeting — review draft PMA structure and anticipated content
- Pre-approval inspection (PAI) — FDA inspects manufacturing facility before approval
Post-approval conditions
FDA approval of a PMA typically includes conditions of approval:
- Post-approval studies (PAS)
- MDR reporting
- Annual reporting
- Device tracking (for certain implants)
- Patient labelling
Failure to comply with conditions of approval may result in withdrawal of approval.
