What are FDA regulations for medical device refulatory affairs?
Medical Device Regulatory Affairs : The U.S. Food and Drug Administration (FDA) is a government-certified agency under the department of health and human services. The FDA has the responsibility of ensuring all the medical devices worldwide are safe and effective for public usage. FDA guidance documents do not establish either practices that are binding on FDA or requirements of law. Therefore, they cannot have the force and effect of law. Rather, guidance represents an agency’s good-faith effort to reflect how it proposes to exercise a particular grant of statutory authority in a particular activity. An agency may depart from its guidance when it determines first principles or other requirements dictate a departure. Guidance, though guidance does reflect the agency’s considered judgement on a topic and can be helpful indications of the current thinking of the agency.
Role of FDA in Medical Devices regulatory Affairs
FDA is the oldest all-inclusive consumer protection government body that was created in 1976 under the legislation of Medical Device Amendments to the Federal Food, Drug, and Cosmetic Act (FD&C Act). The roles of FDA in medical regulatory devices are:
- User Fee Programs
- Promote and protect health
- Covers foods, drugs, biologics, cosmetics, animal and veterinary medicine, as well as tobacco.
- CDRH regulates medical devices as well as radiation-emitting products.
FDA guidelines for Medical device regulatory affairs
The FDA, which has guidelines and regulations in the comprehensive matter, makes sure that those medical devices are safe and effective and also in compliance with the law in the United States. Some of the essential FDA guidelines of relevance to the activities of medical device regulatory affairs are as follows:
Medical devices have been classified into three classes:
I, II, and III on the risk involved and the extent of control that the Medical Devices Regulatory system needs to exercise.
| class | risk | control | Submission | Example |
| I | Low risk | General | typically exempt from premarket notification. | bandages, examination gloves |
| II | Moderate risk | General and special | usually requires a 510(k) premarket notification to demonstrate substantial equivalence to a legally marketed device. | infusion pumps, surgical drapes |
| III | High risk | General and PMA | this typically involves premarket approval, which would be severely tested and include several clinical trials . | pacemakers, implants |
2. Premarket Submissions
- 510(k) Premarket Notification: The most common procedure that Class II devices followed in a procedure was when the manufacturers were required to demonstrate that the device was substantially equivalent to a legally marketed device.
- Premarket Approval (PMA): This would affect most Class III devices. It would be much more extensive, and the intent is to have a clinical need in order to demonstrate that the device is safe and effective.
- De Novo Classification: For low- to moderate-risk devices that lack a similar device available in the marketplace that would provide a pathway for new, class III-like devices without a predicate.
- Humanitarian Device Exemption (HDE): Devices for rare conditions meant for diagnosis or treatment allow enabling approval with less burdensome data requirements.
3. Quality System Regulation (QSR)/ Good Manufacturing Practice
21 CFR Part 820 indicates the quality system requirements for the manufacturers and includes:
- Design controls for designing and developing the products.
- Documentation controls to maintain the compliance-related records.
- Production and process control for the delivery of consistently manufactured products.
- CAPA processes follow corrective and preventive actions
- QSR Maintenance shall ensure that the intended regulatory requirements of the devices are in place for the duration of their life cycle.
4. Labeling and Advertising Compliance
- The devices shall be labelled with appropriate information on them, but clear and FDA-compliant.
- Claims shall be substantiated by data; all claims can’t be misleading or unsubstantiated.
- The majority of medical devices, aside from other labelling rules, need to have UDI labelling that also enables standardisation of identification within the medical devices for improved tracking and patient safety.
5. Post-Market Surveillance and Reporting
MDR: Manufacturers shall notify of adverse events, malfunctions, or situations that may lead to death or a serious injury.
PAS: Some Class III are in post-approval studies, where the long-term safety and effectiveness are monitored.
Correction and Recall: Any correction for safety or removal of any device should report to the FDA.
Tracking Requirements: Some devices will have tracking so that in case of a recall, they can be located immediately and notified.
6. Clinical studies and Investigational Device Exemption (IDE)
- For those devices that contain clinical studies, an IDE permits a device to be used in a clinical study to generate information regarding safety and effectiveness.
- Clinical studies shall be performed according to the purpose of 21 CFR Part 812 and Good Clinical Practices (GCP).
- The FDA requires IRB approval for any clinical study protocol and ensures that the proposal is submitted by the subjects who are conducting the study and that the investigator is qualified.
7. Electronic Signatures (21 CFR Part 11)
- This rule provides guidelines that give rise to principles for electronic records and signatures.
- Electronic systems employed for ensuring compliance, a production process, and record-keeping systems shall be secure with an inherent element of integrity and traceable.
8. Risk Management and Cybersecurity
- The FDA explains the need for risk management as design through the full life cycle of devices (for example, the ISO 14971 standard).
- Manufacturers of digital and connected devices are required to satisfy security requirements so that unauthorised access cannot allow penetration into the functionality of the device or patient data.
9. International Harmonization
- Standards Used: The FDA has followed almost all international standards (for example, for QMS, ISO 13485) as part of the joint initiative to have greater worldwide harmonisation.
- Medical Device Single Audit Program (MDSAP): It supports a single audit that meets the requirements of the U.S., Canada, Brazil, Japan, and Australia, minimising the compliance burden of the multinational firms.
10. Guidance Documents and Resources
- Guidance documents and resources rank as one of the most common types of publications by the FDA regarding specific topics of regulatory interest or new emerging areas like AI in medical devices.
- These papers would educate the manufacturers to learn more specific and timely information regarding requirements and expectations of the FDA.
To achieve any goals in the United States, navigating requirements related to meeting compliance and accessing the market will be key in doing so with the FDA. From classification to quality systems, then post-market surveillance, all work together to provide safety and effectiveness for the device by focusing on public health.
