FDA De Novo Classification Services

Medical device manufacturers developing novel devices without predicate alternatives are automatically assigned a Class III designation unless they pursue De Novo classification. MiCOM Labs provides A2LA-accredited testing services under ISO/IEC 17025 that support De Novo submissions with comprehensive test data required for Class I or Class II reclassification.

Understanding the De Novo Classification Pathway

The De Novo pathway provides a risk-based classification process for novel medical devices that lack legally marketed predicates. The FDA evaluates whether general controls alone or general controls combined with special controls provide reasonable assurance of safety and effectiveness.

When De Novo Classification Applies

Manufacturers pursue De Novo classification under two circumstances:

1

Direct Submission

You determine that no legally marketed predicate device exists for substantial equivalence comparison.

2

Post-NSE Determination

The FDA issues a not substantially equivalent decision following 510(k) review because no predicate device exists.

Substantive Review Confirms

The FDA's review goal under MDUFA V targets 150 FDA review days from submission receipt to decision. This timeline excludes hold periods when the agency requests additional information.

  • No predicate device exists for the technology
  • Proposed classification into Class I or Class II proves appropriate
  • General controls or general controls with special controls ensure reasonable assurance of safety and effectiveness
  • Documentation supports all performance claims

De Novo Submission Requirements — Source: FDA 21 CFR 860.220

Requirement Category Documentation Elements
Administrative Information Device intended use, prescription designation, and cover sheet identifying De Novo request
Device Description Technology overview, proposed conditions of use, accessories, and components
Classification Justification Proposed class designation, rationale for general controls, or general controls with special controls
Safety and Effectiveness Data Clinical data (if applicable), non-clinical bench testing, biocompatibility evaluation, software validation
Risk-Benefit Analysis Comparison of probable benefits vs. risks when the device functions as intended

FDA Review Timeline & Pathway Comparison

The De Novo review follows a structured sequence with defined timelines for each phase.

15 calendar days

Acceptance Review

FDA conducts technical screening via eSTAR, validating submission completeness against 21 CFR 860.230 acceptance criteria. Incomplete submissions trigger a deficiency notification; manufacturers have 180 calendar days to submit a replacement.

150 FDA review days

Substantive Review

FDA review goal under MDUFA V from submission receipt to decision, excluding hold periods when the agency requests additional information.

180-day response window

Additional Information Requests

When deficiencies are identified, an Additional Information letter is issued. Manufacturers have 180 calendar days to respond. No extensions apply — the FDA considers requests withdrawn if the deadline passes.

Testing Requirements for De Novo Submissions

FDA acceptance of De Novo submissions requires test data from laboratories holding ISO/IEC 17025 accreditation. Test results must meet documentation and traceability standards recognized globally by regulatory authorities.

Electrical Safety Testing

Medical electrical equipment requires testing in accordance with IEC 60601-1. Laboratory instruments require testing in accordance with IEC 61010. These standards evaluate:

Insulation integrity and protective earth connections

Leakage current limits under normal and fault conditions

Temperature rise on accessible surfaces

Mechanical stability and resistance to stress

Protection against fluid ingress

Electromagnetic Compatibility Testing

IEC 60601-1-2 establishes EMC testing requirements for medical electrical equipment. Testing validates that devices operate reliably in clinical environments without causing harmful interference.

Emissions Testing

Test Type Purpose Standard
Radiated Emissions Prevents interference with nearby medical equipment IEC 60601-1-2, EN 55032, FCC Part 15
Conducted Emissions Eliminates power line interference in healthcare facilities IEC 60601-1-2, EN 55032
Harmonic Current Protects power grid stability IEC 61000-3-2
Voltage Fluctuations Maintains power quality for life-supporting equipment IEC 61000-3-3

Immunity Testing

Test Type Application Standard
Radiated Immunity Ensures function during RF exposure from wireless equipment IEC 61000-4-3, IEC 60601-1-2
Conducted Immunity Validates operation during power line disturbances IEC 61000-4-6
ESD Immunity Prevents system failure from static discharge IEC 61000-4-2
Surge Immunity Protects against transient-induced failures IEC 61000-4-5

Wireless Device Testing

Connected medical devices must pass RF compliance testing under FCC Part 15, Part 18, or Part 27, depending on the wireless technology. These tests verify emissions limits and ensure devices do not cause harmful interference.

MiCOM Labs performs testing up to 220 GHz and provides certification for FCC, ISED, EU RED, UKCA, and Japan MIC requirements.

Frequently Asked Questions

Devices qualify for De Novo when no legally marketed predicate exists, and the device presents low to moderate risk. The manufacturer must demonstrate that general controls or general controls with special controls provide reasonable assurance of safety and effectiveness.

Yes. Since the FDA final rule in October 2021, manufacturers can submit De Novo requests directly when they determine that no predicate device exists. This eliminates the need to obtain a not substantially equivalent determination first.

The FDA's review goal targets 150 FDA review days, excluding hold periods. Total time from testing initiation through final decision typically ranges from six to nine months, depending on device complexity and the completeness of initial documentation.

The device remains in Class III. Manufacturers must either submit a Premarket Approval (PMA) application or collect additional data to address the identified deficiencies and submit a new De Novo request.

MiCOM Labs provides comprehensive testing services for bench performance, electrical safety, EMC, and RF compliance. For clinical studies, we coordinate with qualified clinical research organizations while managing the overall compliance timeline.
