Sterling Pharma Solutions is a global contract development and manufacturing organisation (CDMO), with 50 years’ experience in small molecule API development and manufacturing services. In April 2021 Sterling acquired ADC Bio, a UK based biotechnology company specialising in antibody drug conjugates and bioconjugation. Together, as Sterling Pharma Solutions, the teams have developed an integrated service offering for existing and potential customers, which combines ADC Bio’s expertise with Sterling’s high potency small molecule expertise.

Sterling has four facilities employing more than 800 people: its HQ in Dudley, Northumberland, UK; a dedicated bioconjugation and ADCs facility in Deeside, North Wales, UK; and two sites in the US, in Cary, North Carolina and Germantown, Wisconsin.
