Clinical Services International

What Clinical Services International does

Clinical Services International (CSI) is a privately held UK-based clinical trial supply company founded in 2016 that specializes in sourcing comparator drugs, biologics, biosimilars, and oncology medicines for pharmaceutical and biotechnology trials. The company operates a global depot network spanning 60 countries across six continents, supported by wholly owned subsidiaries in the United States (Horsham, PA), Germany (Berlin), and China (Shanghai). Its core technical capability is GDP- and GMP-compliant cold chain logistics at 2-8°C, -20°C, and -80°C with validated packaging, GPS tracking, real-time temperature monitoring, and expiry flagging, complemented by MHRA, LAGeSo, EcoVadis Platinum, Cyber Essentials Plus, UN Global Compact, and SAM.gov/BARDA qualifications. CSI maintains a digitalized global Quality Management System through the Simploud eQMS platform and offers four direct-to-patient distribution models for decentralized trials.

CSI generates revenue through three streams: clinical supply product sales (comparator drugs, medical devices, ancillaries), storage and distribution services (cold chain and ambient), and project management services (protocol analysis, supply planning, budgeting, forecasting, shortage and price-fluctuation risk evaluation). Pricing is quote-based and project-specific, often with manufacturer price guarantees for study duration, and the company sells primarily through enterprise field sales with dedicated client relationship managers. Target customers are top-ten pharmaceutical companies, leading biotechs, Contract Research Organisations, and academic institutions, with selective credentials including supply of ruxolitinib across 14 countries for a global Phase 3 oncology trial, Opdivo sourcing for a 500+-patient Phase III oncology study in 4 countries, and a Humira biosimilar engagement delivering 50% cost savings.
