Patent ID: 8738397

Claim:
A method of randomizing subjects in a multi-arm clinical trial, the method comprising: receiving, by a computing system, a subject identifier, a trial identifier, and a value associated with a state of a subject in at least one randomization factor from an electronic data capture system that assigns the subject identifier to enroll the subject into the multi-arm clinical trial, the trial identifier associated with the multi-arm clinical trial into which the subject is enrolled, the subject identifier indicating the subject enrolled by the electronic data capture system in the multi-arm clinical trial; selecting at runtime, by the computing system, from a database that stores a plurality of randomization design algorithms associated with respective trial identifiers for a plurality of multi-arm clinical trials, a randomization design algorithm previously configured for the multi-arm clinical trial using the trial identifier received from the electronic data capture system; and executing, by the computing system, the randomization design algorithm using the value associated with the state of the subject in the at least one randomization factor that randomizes the subject to an arm of the multi-arm clinical trial, the randomization design algorithm assigning the subject identifier to an arm identifier that indicates the arm of the multi-arm clinical trial to which the subject has been randomized in accordance with the randomization design algorithm for the multi-arm clinical trial.
