Welcome to Clinical Services International
Clinical Services International (CSI) is a world leader in the sourcing and management of quality certified commercially available medicines (comparators, concomitant medication, rescue medication) for clinical trials.
Headquartered in London and with operations in the UK, Germany, and the USA, we provide efficient solutions and serve global trials.
Our longstanding experience in intelligent sourcing and clinical trials enables us to provide custom made solutions to address the most complex requirements.
We accelerate drug development and reduce timelines by providing a fully integrated service.
We are not a pharmaceutical wholesaler:
We are CSI: the science-based clinical trial supply leader.
We are passionate about customer service, quality, innovation, and making rapidly available safe medicines.
