Catalent is your strategic partner for biologic drug development success. We create smart, tailored solutions with our novel SMARTag™ antibody–drug conjugation (ADC) technology, our market-leading GPEx® cell line expression system, expanded biomanufacturing capabilities, and integrated development services to help you get better products to market faster.

New SMARTag ADC Technology for Development of Optimized Antibody–Drug Conjugates — Superior Technology for Treatments in Development: Catalent has entered into an exclusive license and comarketing agreement with Redwood Bioscience to offer customers SMARTag advanced site-specific conjugation technology and linker–toxin combinations to develop optimized antibody–drug conjugates. SMARTag technology is a proprietary approach to help develop improved antibody–drug conjugates. It allows for very precise conjugation and optimal release of the therapeutic agent, providing advantages over existing technologies with precise site-specific drug placement and enhanced potency and stability. It provides better safety, efficacy, and regulatory compliance with increased scalability and manufacturability.

Biomanufacturing Center of Excellence

GPEx (Gene Product Expression) Technology

Progressing Your Pipeline Faster: Catalent’s proprietary GPEx technology enables genetic engineering of highly stable, high-yielding mammalian cell lines with unmatched speed and efficiency. Our proven technology has been expressed in more than 400 cell lines, and our clients have products in clinical trials in both the United States and Europe, with manufacturing occurring at either our Madison, WI site or the client’s site. GPEx technology is distinguished by several important benefits.

Efficiency: GPEx technology uses a vector technology that ensures stable transduction of targeted cells, approaching 100% efficiency — eliminating the need for selectable markers and saving time and cost.

Versatility: Almost any cDNA can be packaged into the GPEx® technology retrovector.

Speed: The process results in high-expressing clonal mammalian lines within five months or less

Flexibility: GPEx® technology can deliver non-cGMP protein, clones, or cGMP protein.
