Our low cost simple service is quick and easy to set up yourself online. By upgrading to our Simple + service you get access to additional customisation features (see below). We recommend our comprehensive service for Clinical Trials of Investigational Medicinal Products (CTIMPs) because it provides a full audit log and role based user accounts.
Why not try the service out by creating a test trial first? This will allow you to become familiar with the way the system works before setting it up for use in your real trial.
Patients are randomised to one of two treatment groups ('A' or 'B') and the result recorded. Randomisation is blocked (using random permuted blocks) to ensure that the groups are balanced periodically.

You can increase the randomisation limit to suit your sample size by buying more randomisations at any time. See pricing.
