Combination Products – Definition & Overview
What is a Combination Product?
As defined by the FDA, a combination product is a therapeutic or diagnostic product that combines drugs, medical devices, and/or biological products. A combination product will combine at least two of these product categories and sometimes combines all three. Some of the most common types include traditional drug device combination products, like a syringe prefilled with a drug, and co-packaged or kitted products, like a first-aid kit containing bandages and pain-relieving drugs.
Types of Combination Products
The Code of Federal Regulations (CFR) classifies combination products as three main types: single-entity, co-packaged, and cross-labeled. A single-entity combination product is comprised of two or more components (drug and device, device and biologic, biologic and drug, or all three) that are combined or mixed to produce a single entity. Examples of single-entity combination products include:
- Prefilled drug delivery devices and systems, such as a prefilled syringe, injector pen, insulin pump or metered dose inhaler
- Prefilled biologic delivery devices and systems, such as a vaccine in a prefilled syringe or nasal spray
- Medical device coated with or otherwise combined with a drug or biologic, such as a transdermal patch or antimicrobial wound dressing
- Drug/biologic combination, such as an antibody combined with a therapeutic drug
A co-packaged combination product consists of two or more components that are packaged together as a unit or in a single package. These combination product types are sometimes also called convenience kits. Some common examples of co-packaging are:
- Drug or vaccine vial packaged with a syringe
- Liquid medication with dose-dispenser
- Surgical tray containing surgical instruments and anesthetic drugs
A cross-labeled combination product is a device, drug, or biological product packaged separately that according to its investigational plan or proposed labeling is intended to be used only with an approved individually specified device, drug, or biological product where both components are required to achieve the intended use, indication or effect. Put simply, these products are sold separately but labeled for use together. A few examples of cross-labeling include:
- Photosensitizing drug and activating laser or light source
- Light-activated biological products not co-packaged but labeled for use with a specific light source device
The Future of Combination Products
The combination product market continues to grow as pharmaceutical, medtech, biotech and life science companies continue to innovate. Combination devices and combination drug products can provide more targeted treatment, enable better drug delivery, and improve the efficacy of both the medical device and the drug. The market for drug device combination products in particular has seen tremendous growth. According to data shared in 2018 by Research and Markets, the global market is expected to surpass $177 billion by 2024.
Patients can benefit immensely from these products that simplify drug delivery. For example, drug delivery devices that allow for easier self-dosing, like a single-use prefilled syringe containing one dose of medication, can help to reduce patient dosing errors and increase compliance. Injection systems and pulmonary inhalers currently dominate the drug delivery combination product market.
Because combination products involve components normally regulated under different types of regulatory authorities, they have unique regulatory challenges. The FDA established the Office of Combination Products (OCP) in 2002 to meet increased regulatory demands for combination products and take a holistic approach to evaluating the safety and efficacy of these products. As this technology continues to evolve, and the market grows, regulatory pathways and policies must continue to evolve as well.
