De Novo classification for devices without a predicate.

When there is no legally marketed predicate, the De Novo pathway creates one. REGARA helps you build the risk-based, special-controls case the FDA needs to grant classification.

What is De Novo?

A pathway for genuinely novel devices.

The De Novo classification request is the FDA route for novel devices of low-to-moderate risk that have no valid predicate and would otherwise default to Class III. A granted De Novo classifies the device into Class I or II and establishes the special controls that future devices of that type can use as a predicate for their own 510(k)s.

Because there is no predicate to compare against, a De Novo lives or dies on its benefit-risk analysis and the special controls proposed to mitigate each identified risk. The documentation burden is closer to a PMA in rigor than a routine 510(k).

REGARA structures the request around the risk framework the FDA applies — drafting the classification rationale, mapping each probable harm to a proposed control, and keeping the evidence for each mitigation traceable.

  • 01
    Benefit-risk drafting

    Draft the classification summary and benefit-risk analysis against current De Novo guidance, with each conclusion anchored to its supporting data.

  • 02
    Special-controls mapping

    Map every identified probable harm to a proposed special control and the evidence that shows it is adequate — the heart of a grantable De Novo.

  • 03
    Precedent research

    Surface granted De Novos and their special controls for comparable device types to calibrate what the FDA has accepted before.

  • 04
    Reviewer simulation

    Anticipate the classification questions a lead reviewer will raise, and close the gaps before submission.

How REGARA helps

Risk, mitigation, and evidence — connected end to end.

Why it matters

Why De Novo is a different kind of submission.

01 · No predicate

You define the type.

A De Novo doesn’t compare to an existing device — it creates a new classification. The reasoning has to stand entirely on its own.

02 · Special controls

Mitigation is the argument.

The FDA grants based on whether your proposed special controls adequately mitigate each risk. REGARA keeps that mapping explicit and evidenced.

03 · Downstream value

You become the predicate.

A granted De Novo becomes the predicate for an entire device category — a strategic asset worth getting right.

  • Q
    What is a De Novo classification request?

    A De Novo request asks the FDA to classify a novel low-to-moderate-risk device into Class I or II when no legally marketed predicate exists. Without it, such a device would automatically fall into Class III and require a PMA.

  • Q
    When should I use De Novo instead of a 510(k)?

    Use De Novo when your device has no valid predicate to establish substantial equivalence but is not high-risk enough to warrant a PMA. If a suitable predicate exists, a 510(k) is usually the faster route.

  • Q
    What are special controls?

    Special controls are the specific requirements — performance standards, labeling, biocompatibility, clinical data, and more — that the FDA determines are necessary to provide reasonable assurance of safety and effectiveness for a device type. They are proposed in the De Novo and reused by later 510(k)s.

  • Q
    How does REGARA help with a De Novo?

    REGARA drafts the classification and benefit-risk narrative against current guidance, maps each probable harm to a proposed special control with traceable evidence, and surfaces comparable granted De Novos so your case reflects what the FDA has accepted.
