Patheon, a business unit of DPx Holdings B.V., delivers a combination of unrivaled quality, reliability and compliance, with a reputation for scientific and technical excellence to customers in the pharmaceutical and biopharma sector. A leading global provider, offering a comprehensive set of solutions to help customers of all sizes satisfy complex development and manufacturing needs at any stage of the pharmaceutical development cycle.

The company enables its customers to bring drug candidates from preclinical stages through to clinical trials, the NDA approval process and, if approved, commercial manufacturing. Patheon's development and commercial manufacturing capabilities cover primarily prescription (Rx) products in solid and sterile dosage forms, as well as specialized capabilities in high potency, controlled/sustained release, and sterile manufacturing, including aseptic filling and lyophilization.

Patheon’s key capabilities for biologics include flexible, technology-based process development, clinical and commercial cGMP manufacturing for mammalian cell culture derived biopharmaceuticals and chemical bulk drug substances. Patheon can serve early, late and commercial stage markets providing end-to-end solutions to customers through its four biologics sites in the U.S., Europe and Australia.
