Who We Serve: Technology

Combination Products

A prefilled syringe, a drug-coated device or an autoinjector has to satisfy more than one quality framework at once. Most gaps sit at the interface between the constituent parts, where the drug team and the device team each assume the other owns the record. We help combination product makers find those seams.

Typical Regulatory Exposure

FDA assigns a combination product to a lead center based on its primary mode of action, the single mode that provides the most important therapeutic action of the product. That assignment shapes the premarket pathway and which part of FDA leads the review, but it does not remove the requirements that apply to each constituent part.

21 CFR Part 4 sets the current good manufacturing practice requirements for combination products, describing how drug and device requirements apply when constituent parts are combined. Firms need to show, in procedures and in records, how they meet the requirements that apply to each constituent part, including design and development and risk management for the device side.

Postmarket obligations also cross frameworks. Complaint handling, adverse event reporting and change management can carry requirements from both the drug and device sides, depending on how the product is regulated and who holds the application. Mapping those obligations explicitly before an inspection costs far less than reconstructing them during one.

Where Audits Find Gaps

  1. 01

    No Map of Which Requirements Apply

    The quality manual does not say which drug and device requirements govern which constituent part, so procedures cover one framework well and the other by accident.

  2. 02

    Device Constituent Without Design Controls

    The delivery device was sourced or adapted from a supplier, and the design file treats it as a purchased component rather than a design with its own inputs, verification and risk analysis.

  3. 03

    Interface Testing Nobody Owns

    Drug-device compatibility, dose accuracy and container closure testing belong to neither team's procedures, so they were run once and never revisited after later changes.

  4. 04

    Use-Related Risk Underestimated

    Patients or caregivers administer the product, but human factors work was scoped like a drug label review rather than a device usability program.

  5. 05

    Reporting Paths Split by Team

    Drug safety and device complaint handling run separately, with no defined process for deciding which reporting requirements a given event triggers.

Questions

How is the lead center decided?

By the product's primary mode of action, the mode that provides its most important therapeutic action. Where that is unclear, firms can ask FDA's Office of Combination Products for a formal or informal determination.

Do we need two complete quality systems?

Not necessarily. 21 CFR Part 4 describes how drug and device requirements apply together, and the right structure depends on your product and your existing quality system. What matters is that each applicable requirement is clearly covered and backed by records.

We buy the device constituent from a supplier. Who owns the design records?

You remain responsible for the combination product, so you need enough design and risk information to show the device constituent meets its requirements in your product. Quality agreements and supplier controls are where that access is defined.
