Products

One product, two sets of rules

Why Combination Products Are Different

Two Sets of Rules, One Product, No Room for Guesswork.

A drug-device or biologic-device combination sits astride two entire regulatory frameworks at once, and one early decision governs everything downstream: the primary mode of action determines which FDA center leads your review, which application you file, and which quality system you build. Get the classification or jurisdiction wrong and you rework years of development. We help sponsors settle the determination early, engage the Office of Combination Products with a defensible position, and build a program that satisfies drug, biologic, and device expectations without doing everything twice.

Where drug meets device

Autoinjectors, prefilled syringes, and inhalers, where two rulebooks apply to one product.

One Determination Sets the Program in Motion

Primary Mode of Action Decides Who Leads.

The primary mode of action assigns your lead center, and the lead center sets your application, your quality expectations, and your review culture. You do not have to guess it: a pre-RFD gets FDA on record before you build around the answer.

The one question that routes everything
What is the product's primary mode of action?
Drug
CDER
Files an NDA that carries the full device constituent story.
Biologic
CBER
Files a BLA that carries the full device constituent story.
Device
CDRH
Files a PMA or 510(k) that carries the drug or biologic constituent.
Drug-device combination product whose primary mode of action decides the lead FDA center
One product, two constituents

The drug and the device ship as one, but the primary mode of action decides who leads the review.

Two Constituents, Two Burdens of Proof

Whichever Leads, the Other Still Has to Prove Itself.

A combination product is one thing to a patient and two things to a regulator. Even when the drug provides the primary mode of action, the device constituent carries a burden the drug program cannot discharge for it.

One program, two disciplines

The chemistry and the mechanism, each held to its own standard and reconciled into a single filing.

Constituent One

The Drug or Biologic

Governed by drug or biologic cGMP.

The active, its CMC, its stability, and its container-closure, held to the standard of the medicinal product it is. Usually where the science that justifies the product lives.

Constituent Two

The Device

Governed by design controls and the Quality System Regulation.

Use-related risk analysis, human factors validation, and design verification. Even as “delivery,” it has to prove it is safe and usable in real hands, or the whole submission waits on it.

21 CFR Part 4

Two Quality Systems, or One Built the Smart Way.

Part 4 lets a combination product comply two ways. The choice shapes cost, inspection exposure, and how much you build twice, and it is far easier to make deliberately at the start than to unwind at scale.

Part 4, decided early

The quality architecture is far cheaper to design once than to reconcile after scale-up.

Option A

Run Both Systems in Full

Operate drug cGMP and the device Quality System Regulation completely and independently. Conceptually simple and easy to explain to an inspector, but duplicative in effort, records, and oversight.

Best when the two constituents are made in separate facilities under separate teams.
Option B

Build One Streamlined System

Base the quality system on one framework and layer in the specified provisions of the other, so a single system satisfies both. Less duplication, but it demands deliberate design and a team fluent in both worlds.

Best when one integrated operation produces the finished combination product.

Where Combination Programs Stall

The Missteps That Cost Years.

Every one of these is a decision, not an accident, and each is far cheaper to get right at the start than to discover at review.

Assuming the primary mode of action
You build the wrong quality system and file to the wrong center, then rework years of development to match the answer FDA actually gives.
Treating the device as packaging
The device constituent skips design controls and human factors, and the submission stalls on usability the drug data cannot rescue.
Leaving human factors to the end
A validation study that fails late forces a redesign after the drug program is already locked, resetting the timeline.
Two disconnected quality systems
Duplicated effort, conflicting records, and an inspection that finds every seam between them.
The Article 117 surprise
A CE-marked combination discovers, months from EU launch, that it needs a notified body opinion on the device part.
The diligence gap
An acquired product carries an undocumented PMOA rationale or a thin human factors file that surfaces mid-deal, at the worst moment.

Each stall is a decision, not an accident

The device constituent, the quality architecture, the Article 117 opinion — all cheaper to get right at the start than at review.

Beyond the Filing

Global, Post-Market, and When It Changes Hands.

The combination does not stop being two things after approval. Three fronts stay live for the life of the product.

Global

Europe Sees It Differently

Outside the US the same product can be regulated as a medicinal product with a device part, and EU MDR Article 117 requires a notified body opinion on the device constituent. We build the global plan around that split.

Post-Market

Two Reporting Regimes

The combination product safety reporting rule pulls together drug adverse-event reporting and device malfunction obligations, on combined timelines. We build the single system that satisfies both without gaps.

Diligence

Read Before You Buy

Legacy combinations often carry undocumented PMOA rationales, thin human factors files, or a quality system built for only one constituent. We read it cover to cover before it becomes your finding.

Who You Work With

People Who Have Filed on Both Sides of the Line.

A combination product punishes specialists who only know one half. Your leads are senior regulatory and quality practitioners who have carried drug, biologic, and device programs, settled jurisdiction with the Office of Combination Products, and built the Part 4 systems that pass inspection.

Both Frameworks

Drug, biologic, and device experience in one team, so nothing falls into the gap between them.

Jurisdiction-Fluent

We settle PMOA and center assignment early, with a pre-RFD or RFD strategy that gets FDA on record.

Part 4 by Design

A quality architecture chosen deliberately for your operation, not stitched together after scale-up.

US and EU

One plan that anticipates Article 117 and the ex-US route, so the global launch does not fragment.

The Work a Combination Product Draws On.

A combination touches drug, device, and global programs at once. These are the services it reaches for most.
