Comparators and Reference Listed Drugs

Clinical Trials: Avant-Garde Approach

We offer a fully integrated service for Comparator Sourcing

The majority of drug candidates are being studied against the existing standard of care (COMPARATORS). As a result the need for secure and transparent comparator sourcing of reference listed drugs (RLD) and non-investigational medicinal products (NIMPs) on a global scale is paramount.

CSI has unique experience and expertise:

  • In depth understand of Clinical Trials Requirements
  • Regulatory advice and support
  • Experienced in import and export, logistics and distribution
  • Manage the entire supply chain and also offer bespoke solutions
  • Global network of audited suppliers, originators and dedicated wholesalers.
  • Medical Devices
  • Our high technology systems ensure quality and smooth process
  • Tailor-made Bespoke Solutions for every single enquiry.

A Reference Listed Drug (RLD) is an approved drug product to which new generic versions are compared to show that they are bioequivalent. A drug company seeking approval to market a generic equivalent must refer to the Reference Listed Drug in its Abbreviated New Drug Application (ANDA).

CSI can source and supply RLD, as required, (specific batches, expiry) on a global scale.

Innovative Solutions

The thing that makes our comparator sourcing stand out is we consolidate everything into a single service. We can arrange to supply and store drugs, providing labelling, and ensure products arrive on time. We cater for bulk orders and use a reliable distribution network to ensure safety and reliability.


There are several great benefits with our service. Firstly we can reduce the set-up time for trials. As a result this can cut the overall cost and speed up the time to market. The fact we only supply approved drugs with full certification also means we increase the accuracy and integrity of the trials.

One concern many organisers have when they trial a drug is waste. Luckily our service keeps this to a minimum, saving clients even more money.

Another advantage we offer is availability. We have a worldwide network that includes manufacturers and distributors. Therefore we can cater for a wide array of therapeautic areas and dosages. Whatever your needs, we can cater for them.
