Clinical Services International - Intelligent Comparator Sourcing

Clinical Services International (CSI) is a leading provider of sourcing and management of quality certified commercially available medicines (comparators, concomitant medication) for clinical trials. Headquartered in London and with operations in UK, Germany and 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.

The gold standard for clinical trial supply

We are the Gold Standard for clinical trial supply. We boost trial success rates, by ensuring the right comparator medicines and devices are ready for trial participants, at the right time, everywhere they're needed - even for the most complex adaptive trials. This accelerates drug development and improves the lives of patients worldwide.

We use our science-led approach, operational expertise and global experience to effectively, ethically and efficiently specify, source and supply comparators and devices.

De-risking clinical trials

CSI de-risks clinical trials. With the experience to support our partners, we advance trial success. We safeguard quality, compliance, and transparency across the entire supply chain.

For pharmaceutical and biotech clients, CSI optimises and de-risks the entire supply chain by ensuring the right products are in the right place at the right time. We serve pharmaceutical companies with growing trial pipelines, facilitating optimal trial performance.

For CROs, CSI is able to take over management of the entire comparator sourcing supply chain on their behalf, leaving them free to concentrate on their specialist skill: finding patients and delivering successful trials.

For CMOs/Packaging clients, CSI takes on the burden of the very toughest sourcing challenges - high cost products that require considerable work to source to those on shortages often at short notice. 'Mission Impossible' in the world of comparator medicines.

Mission Impossible Delivered

Finding the unfindable. Every trial is unique, and complex. Our agile approach means we're able to deliver the complex and the urgent. From supplying Comparators to thousands of patients, to finding solutions for urgent immuno-oncology drugs in short supply, no task is beyond our capability.

A science led approach to managing complexity and avoiding disruption. With several decades of combined experience in drug development, we can provide fully integrated one-stop solutions. We assist clients with comparator identity, strategic guidance around protocol, and provide cross market regulatory advice. We act as a control tower to optimise drug supply.

We forecast and manage supply chains to ensure product quality, safety and security standards are adhered to at every stage of the trial. And do all this to the most stringent budgets and timelines.

Operational Excellence

We're setting the new standard for ethical comparator sourcing. And by doing so we safeguard clinical trials everywhere, ensuring they have their best chance of success in improving patient outcomes.

CSI offers secure and transparent sourcing of products for a broad range of trials, across all therapeutic indications.
We maintain stringent operating procedures to guarantee quality in everything we do. Our trusted network of suppliers is fully audited. We are fully compliant with the Falsified Medicines Directive and can prove the authenticity of each product we source.

Our Regulatory and Quality Assurance experts have longstanding relationships with the FDA, MHRA and EMA .

In the complex world of global clinical trials, CSI safeguards the progress of medicine.
