The management of multiple cohorts is a standard offering of most IRTs. In the common sequential model, when Cohort 1 reaches a pre-designated limit the cohort is closed by the system and subjects can no longer be enrolled into that cohort. Problem: The design of your study is such that the maximum number of subjects in each of your four planned cohorts cannot be fixed at study startup, and more than one cohort can, in certain circumstances, be open simultaneously. How should the IRT be set up to provide this kind of adaptability?
The Veracity Logic Solution:
A typical approach to achieving flexible cohort functionality is to assign the task to the system development team. Programmers and configuration managers would modify code or system configurations during the trial as needed to adjust cohort parameters. Additional costs, time delays, and the need to produce change orders and approval documents for interparty communication, are three notable downsides to this approach.
Veracity Logic's IRT platform supports an alternate strategy. In addition to system controls, we offer a user-friendly, manual approach that puts the power of change directly into the hands of authorized users. Cohort parameters are configurable, no coding changes required. Cohort limits can easily be modified and re-modified with the click of a button. Likewise, cohorts can be manually opened and closed, re-opened and re-closed on demand, all by the users themselves, and in the users' own timeframes.
