Combination Products

Combination products are therapeutic and diagnostic products that combine drugs, devices, and/or biological products and can include combinations of the following types: drug-device, biologic-device, drug-biologic and drug-device-biologic. They can be physically or chemically combined, packaged together as a kit, or be separate, cross-labeled products. Examples of combination products include: prefilled syringes, antimicrobial-coated catheters, co-packaged products that are required to be delivered sequentially for therapeutic effect, biologic or synthetic surgical patches that are pre-packaged into delivery devices, and drug-eluting stents.

Combination product manufacturers face numerous challenges getting new products to market, including developing appropriate preclinical and clinical plans to evaluate safety and effectiveness, preparing compelling regulatory submissions, and developing comprehensive post-marketing strategies. From a business standpoint, it is important that clients understand the market and reimbursement strategies for their products under development. Given their multidisciplinary nature, combination products become more challenging with regard to regulatory compliance, product development, intellectual property, and failure analysis.

Exponent provides the highest quality engineering, regulatory, safety assessment, epidemiological, and health economics services to assist our clients with matters related to combination products. We specialize in providing rapid, focused, market-sensitive solutions to complex topics.

Combination Drug Product Development Assistance

We assist with combination drug product development and CMC issues during pre-clinical, clinical, and post-marketing development phases, including primary container selection and development, container closure development and testing, drug delivery system (DDS) selection and development, toxicology, pharmacology, formulation development, and improvement; compatibility of the DDS with the targeted formulations, primary container and DDS manufacturing and process scale-up; development of DDS sections of combination product clinical trials, instrument development/validation and data analysis for DDS systems during clinical trials, DDS therapy modeling, stability of drug delivery combination products, product performance optimization and improvement, and product safety and reliability.

Antimicrobial Devices

Device-related infections are a serious complication associated with many types of implantable devices, including catheters and stents. Antimicrobial applications may be an effective approach for inhibiting microbial adhesion to and colonization of devices. Exponent staff have extensive experience in the development and evaluation of antimicrobial-device combinations, including coatings and bio-responsive polymers.

Regulatory Agency Assistance

Exponent has successful experience with the regulatory agency interactions and communication with healthcare professionals for new single entity, as well as fixed-dose combination product submissions.
