Inveresk Clinical Research

Inveresk was a prominent global contract research organization (CRO) that provided a full suite of drug development services to the pharmaceutical and biotechnology industries. The company specialized in preclinical safety assessments and clinical trial management across all phases of development, from Phase I through Phase IV. Originally established in Scotland in 1969, Inveresk grew into a major international player, significantly increasing its clinical capabilities through the acquisition of ClinTrials Research in 2001. In 2004, the company was acquired by Charles River Laboratories in a deal valued at approximately $1.5 billion, integrating its clinical and preclinical expertise into Charles River's broader portfolio. Following the acquisition, the clinical research division was eventually divested to Kendle International in 2006.
