A PMA is the application for approval of a class III device. The FDA
reviews it without a comparison device: it asks whether valid scientific
evidence provides reasonable assurance that the device is safe and effective
for its intended use (21 CFR 860.7). The outcome is an approval order with
conditions that bind manufacturing, labeling and advertising (21 CFR 814.80).
Between receipt and decision there are fixed stations. The FDA files the
application for review, may refer it to an advisory panel that meets in
public (21 CFR 814.44(b)), and answers with approval, an approvable letter,
a not approvable letter or denial. If the applicant does not respond in
writing to a request for an amendment or to one of these letters within 180
days, the PMA is considered withdrawn (814.44(g)).
How the application reaches the FDA is the applicant's choice.
| Traditional PMA | Modular PMA |
|---|
| What is submitted | the complete application under 21 CFR 814.20 at once | modules following a shell agreed in advance, the last one with clinical data, labeling and SSED |
| When the FDA reviews | from receipt of the complete application | each module on its own, FDA goal: a response within 90 days |
| When the 180 days start | on filing | on filing after the final module, typically the date that module is received |
| When it fits | when all data are available at the same time | when the clinical investigation is at an early stage and the design is fixed |
Inspections accompany the PMA in two places: in manufacturing, whose
compliance with Part 820 the FDA can make a condition of approval, and in the
records pertinent to the PMA (if applicable) it can verify at the same time
(21 CFR 814.44(e)(1)(iii)); the
modular PMA keeps the bioresearch monitoring information in a separate module.
