It covers the FDA review process, timelines, and performance goals for De Novo requests.
Recommended Actions
- Ensure user fee payment and valid eCopy/eSTAR submission before filing
- Follow the acceptance review checklist to ensure submission completeness
- Implement quality system to ensure compliance with:
- Clinical investigation requirements
- Non-clinical study requirements
- Labeling requirements
- Plan for interactive review process to efficiently resolve deficiencies
- Track review timelines and respond promptly to FDA requests:
- 15 days for acceptance review
- 180 days maximum to respond to additional information requests
- 150 FDA days target for final decision
- Maintain documentation of compliance with all applicable regulations
- Consider requesting discussion with FDA if decision not reached within 180 FDA days
- Ensure facilities are prepared for potential FDA inspections
- Monitor submission status and maintain active communication with FDA throughout review process
Key Considerations
Clinical testing
- Clinical investigations involving human subjects must comply with IRB regulations (21 CFR part 56), informed consent regulations (21 CFR part 50), and GCP (21 CFR 812.28(a))
- Clinical studies must be completed per protocol and adequately address any deficiencies identified
Non-clinical testing
- Nonclinical studies subject to 21 CFR part 58 must be conducted in compliance with these regulations
- Any non-compliance must be justified and the practices used must support study validity
Labeling
- Device labeling must comply with requirements in 21 CFR parts 801 or 809 as applicable
Safety
- General controls or general and special controls must provide reasonable assurance of safety and effectiveness
- Facility inspections must support that controls provide reasonable assurance of safety and effectiveness
Other considerations
- Submissions require user fee payment and valid eCopy/eSTAR
- 15-day acceptance review timeline
- 150 FDA days review goal with performance targets increasing from 70% to potentially 90% by FY2027
- Interactive review process available for resolving deficiencies
- Withdrawal occurs if no response within 180 days of additional information request
