Comparator medicines for clinical trials
We identify, procure and deliver comparator medicines from licensed sources, fully documented — for sponsors, CROs and clinical supply teams.

In a comparative clinical trial, the comparator medicine matters as much as the investigational product: without it the study cannot start, and any uncertainty about its origin or storage conditions calls the data of the whole trial into question. Our service solves exactly that problem: comparators with verified provenance, complete documentation and delivery under controlled conditions.
The comparator sourcing challenge
Sponsors and contract research organisations (CROs) run into the same obstacles again and again: limited market availability, single-batch requirements for study consistency, minimum shelf life dictated by treatment duration, cold chain products that do not forgive transport errors and — perhaps most importantly — the need to document every link of the supply chain for the trial master file.
The European market offers a real advantage: centrally authorised products with the same composition as everywhere else in the European Union, often available at competitive cost. As an ANMDMR-authorised distributor (Wholesale Distribution Authorisation no. 716D), GDP-certified and with access to a network of licensed EU suppliers, we put that advantage to work for your trials.
What you receive, concretely
For every comparator supplied, you receive the product in the agreed batch, quantity and shelf life, together with the documentation package your file requires: certificate of analysis (CoA) where available, provenance documents evidencing the chain of custody from the licensed source, and the record of temperature conditions during storage and transport. Delivery goes to the central trial depot or, where the protocol requires, to sites — in qualified packaging, with temperature monitoring.

Frequently asked questions
What is a comparator medicine?
An already authorised medicine used in a clinical trial as the benchmark for the investigational product — either as an active reference treatment or as the basis of the control arm. Its quality and provenance directly influence the validity of the trial results.
Why does the source of the comparator matter so much?
Because authorities and auditors require proof that the product came through a licensed distribution chain and was stored correctly at every stage. A comparator without complete provenance documentation can compromise the study data.
Can you secure single batches or a minimum shelf life?
Yes. Single-batch and minimum shelf-life requirements are part of the specifications we confirm before quoting, together with actual market availability.
Do you deliver to central depots or directly to sites?
Both are possible: we deliver to the central trial depot or, where the protocol requires, directly to investigation sites — always under temperature-controlled conditions.
What documentation do we receive on delivery?
The standard package includes provenance documents evidencing the chain of custody, the record of batches and expiry dates, the temperature history of the transport and the certificate of analysis, where available from the manufacturer.
