PMA (Premarket Approval)
Premarket Approval Application
Legal Requirement: This regulation is legally binding and must be complied with for US market access. Non-compliance can result in regulatory action, including warning letters, import detentions, and product recalls.
Overview
Scope
Premarket Approval (PMA) is the most stringent type of device marketing application required by FDA. PMA is required for Class III medical devices, which are devices that support or sustain human life, are of substantial importance in preventing impairment of human health, or present a potential unreasonable risk of illness or injury. PMA requires demonstration of safety and effectiveness through valid scientific evidence, typically including clinical data.
Applicability
PMA is required for Class III medical devices. Most Class III devices are those that were on the market before 1976 and were automatically classified as Class III, or new devices for which there is insufficient information to determine that general controls or special controls provide reasonable assurance of safety and effectiveness. Some devices may be down-classified from Class III to Class II through the de novo process.
Why It Matters
PMA approval is required before Class III devices can be legally marketed in the US. The PMA process is rigorous and requires comprehensive scientific evidence of safety and effectiveness. PMA approval provides market exclusivity benefits. Without PMA approval, Class III devices cannot be sold. The PMA process typically takes longer than 510(k) and requires more extensive data, including clinical studies.
Key Concepts
- Safety and effectiveness demonstration
- Valid scientific evidence
- Clinical data requirements
- IDE for clinical studies
- 180-day review timeline (often longer)
- Advisory panel review (may be required)
- Post-approval requirements
- Supplemental PMA for changes
- PMA annual reports
PMA devices help patients with the most serious conditions. The regulatory bar is appropriately high.
PMA is the most rigorous FDA pathway—required for Class III devices. Unlike 510(k), you must prove safety and effectiveness with valid scientific evidence, typically including clinical data. This is a multi-year, multi-million dollar process. Plan accordingly.
🔑 Key Takeaways
- →Start Pre-Sub meetings with FDA early—they help shape your clinical study design.
- →IDE approval is required before enrolling patients in your clinical study.
- →PMA review takes 180+ days minimum. Plan your timeline realistically.
- →Post-approval requirements include annual reports and supplemental PMAs for changes.

PMA Application Requirements
Device Description
Provide comprehensive description of device including design, materials, components, manufacturing processes, and specifications. Include detailed technical documentation, drawings, and diagrams. Describe device operation and key features.
Indications for Use
Clearly define intended use, indications for use, target patient population, and use conditions. Describe clinical benefits and how device addresses medical need. Compare to available alternatives.
Preclinical Studies
Include all non-clinical testing data: electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), laser safety (if applicable), software validation (IEC 62304), usability (IEC 62366), biocompatibility (ISO 10993), animal studies, bench testing, and reliability testing. All testing must be conducted per applicable standards and GLP where required.
Clinical Data
Provide clinical study data demonstrating safety and effectiveness. Clinical studies must be conducted under IDE (Investigational Device Exemption) if device is not cleared/approved. Include study protocols, informed consent forms, IRB approvals, case report forms, statistical analysis, and clinical study reports. Data must demonstrate reasonable assurance of safety and effectiveness.
Manufacturing Information
Provide detailed manufacturing information including: manufacturing processes, quality control procedures, facility information, process validation, and quality system compliance (21 CFR 820). FDA may inspect manufacturing facilities.
Labeling
Include all proposed labeling: device labels, instructions for use, user manual, patient labeling, and any promotional materials. Labeling must be truthful and not misleading. Include all warnings, precautions, contraindications, and adverse effects.
Environmental Impact
Provide environmental assessment per 21 CFR 25, unless device qualifies for categorical exclusion. Most medical devices qualify for exclusion, but certain device types may require environmental assessment.
Financial Disclosure
Disclose financial interests and arrangements with clinical investigators per 21 CFR 54. This includes compensation, proprietary interests, equity interests, and other financial arrangements that could bias study results.
PMA Submission Process
Determine PMA Requirement
Confirm device is Class III and requires PMA. Review FDA device classification. Consider de novo pathway if appropriate. Engage FDA early through Pre-Submission meetings.
Obtain IDE Approval
Submit IDE application for clinical studies. Obtain IRB approval and informed consent. IDE must be approved before enrolling patients. Conduct clinical studies per IDE and ISO 14155 requirements.
Complete Preclinical Testing
Conduct all non-clinical testing: electrical safety (NRTL), EMC (NRTL), laser safety, software validation, usability, biocompatibility, animal studies, bench testing. All testing must be per applicable standards and GLP where required.
Conduct Clinical Studies
Design and conduct clinical studies to demonstrate safety and effectiveness. Studies should be well-controlled with appropriate endpoints. Collect clinical data per study protocol. Analyze data statistically.
Prepare PMA Application
Prepare comprehensive PMA application including: device description, indications for use, preclinical data, clinical data, manufacturing information, labeling, environmental assessment, and financial disclosure.
Submit PMA Application
Submit PMA application through FDA Electronic Submission Gateway (ESG). Ensure all required sections are complete. Include all supporting documentation. Keep submission confirmation and tracking number.
Respond to FDA Questions
Monitor submission status. Respond promptly to FDA requests for additional information. Prepare for advisory panel review if required. FDA may inspect manufacturing facilities and clinical sites.
Post-Approval Compliance
After PMA approval: submit annual reports, report adverse events per 21 CFR 803, submit PMA supplements for changes, maintain quality system compliance, and comply with post-approval study requirements.
Common Challenges & Solutions
IDE approval and clinical study conduct
Submit IDE application early. Work closely with FDA on study design. Ensure IRB approval and informed consent. Conduct studies per protocol and GCP. Monitor studies closely.
Insufficient clinical data
Design studies to provide valid scientific evidence. Include appropriate controls and endpoints. Ensure adequate sample size. Consider FDA guidance on clinical study design for device type.
FDA inspections
Ensure manufacturing facilities comply with 21 CFR 820. Prepare for FDA inspections. Have all documentation readily available. Address inspection findings promptly.
