Randomisation services

Sealed Envelope™ is dedicated to providing 24 hour, 365 day a year randomisation services for clinical trials using both internet and telephone based systems.

Our internet randomisation services allows investigators to randomise patients from anywhere in the world through the convenience of their web browser. We offer a basic free randomisation service intended for small unblinded non-commercial trials. We also offer a comprehensive service that is fully customised to each trial. Key features are:

internet

Our telephone randomisation service uses automated response technology (sometimes called IVR or IVRS) to allow investigators to randomise patients using their telephone keypad. Key features are:

telephone conversation

Whichever system you choose, you'll benefit from our high standards of service and attention to detail. Peer reviewers will be assured that randomisation was carried out centrally and randomisation data held independently from other patient records at the data-collection centre. See more information on the problems of using real envelopes to appreciate the advantages of centralised randomisation.
