Controlled Substances

Polymer Drug Conjugates

Over the last 10 years, JMPS has developed substantial expertise and proficiency in polymer drug conjugate chemistry. Our team of accomplished scientists effectively plan and execute the development and scale-up processes for linking small molecule payloads to polymers in support of PDCs, ADCs, and other drug delivery applications.

You can trust Johnson Matthey as your CMO/CRO partner for development and production services throughout the lifecycle of your PDC.
