Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 5, 2026 ## Definition Premarket Approval (PMA) is the FDA process of scientific and regulatory review to evaluate the safety and effectiveness of Class III medical devices. PMA is the most stringent type of device marketing application required by the FDA. ## What this means in practice PMA submissions must include valid scientific evidence, typically from adequate and well-controlled clinical investigations, that the device is [safe](/terms/safe-note) and effective for its [intended use](/terms/intended-use). They also undergo a [Pre-Approval Inspection](/terms/pai) (PAI) of the manufacturing facility. Post-approval, PMA devices remain subject to conditions of approval, post-approval studies, and annual reports. ## Examples - An implantable cardiac defibrillator approved via original PMA supported by a pivotal randomized trial. - A new indication for an existing PMA device pursued through a PMA Supplement rather than a new original PMA. ## Use cases 1 scenario 1 ### Novel implantable neurostimulator Clinical & RA team An implantable device for treatment-resistant depression has no predicate. The sponsor runs an [IDE](/terms/ide)\-authorized [pivotal trial](/terms/pivotal-trial), then submits a PMA with full clinical, manufacturing, and [biocompatibility](/terms/biocompatibility) data, plus a cybersecurity plan for the patient programmer. Outcome After a panel meeting and inspection, FDA grants PMA approval with post-approval study commitments. Common pitfalls - • Assuming a 510(k) pathway will work for novel high-risk devices. Class III devices default to PMA unless reclassified. - • Underestimating the manufacturing inspection component (PAI); GMP nonconformities can delay approval regardless of clinical data quality. - • Building a clinical program without an early FDA Pre-Submission (Q-Sub) meeting to align on endpoints, control, and statistical plan. - • Confusing PMA approval with 510(k) clearance in labeling and marketing materials. ## Frequently asked questions What is the difference between 510(k) and PMA? 510(k) results in clearance based on [substantial equivalence](/terms/substantial-equivalence) to a [predicate device](/terms/predicate-device) and is used for most Class II devices. PMA results in approval based on independent evidence of safety and effectiveness (usually clinical trials) and is required for Class III devices without a suitable predicate. How long does PMA review take? What is a PMA Supplement? Are clinical trials always required for PMA? ## Cross-references ### Governed by Regulations or standards this term must comply with. - [ Quality System Regulation(QSR / 21 CFR 820) ](/terms/qsr) ### Uses Concepts or artefacts this term builds on. - [ Investigational Device Exemption(IDE) ](/terms/ide) - [ Pre-Approval Inspection(PAI) ](/terms/pai) ### Often confused with Distinct concept frequently mistaken for this one. - [ 510(k) Premarket Notification(510(k)) PMA is approval; 510(k) is clearance. ](/terms/510k) ### See also Closely related context worth reading. - [ Class III Device ](/terms/class-iii) ## Related terms Grouped by theme ### Editor's picks · Hand-selected related concepts [ Regulatory 510(k) Premarket Notification(510(k)) FDA submission demonstrating a device is substantially equivalent to a legally marketed predicate. ](/terms/510k)[ Regulatory Substantial Equivalence(SE) The legal standard a 510(k) device must meet versus a predicate. ](/terms/substantial-equivalence)[ Regulatory Class III Device FDA's highest-risk device class, generally requiring PMA. ](/terms/class-iii)[ Clinical & Trials Investigational Device Exemption(IDE) FDA authorization to use an investigational device in a clinical study. ](/terms/ide) ### De Novo & Breakthrough Pathways · From this learning path [ Regulatory De Novo Classification Request(De Novo) Pathway to classify novel low- to moderate-risk devices that lack a predicate.
