Here’s the Adaptive Trial Process.


Adaptive Clinical Trial Design
Allow the pre-specification of flexible components to the major aspects of a trial, like the treatment arms, the allocation to the different treatment arms, the patient population, and the sample size.
Trial Implementation
Our services include interim and final analyses for primary and key secondary efficacy endpoints, providing expert guidance on best practices for adaptive design implementation, and interacting with Data Safety Monitoring Boards (DSMB) for adaptive and platform trials.
Clinical Trial Software
Software solutions that help Biostatisticians rapidly design, compare, and simulate both fixed and adaptive trial designs through powerful, versatile and fast simulation tools.
Platform Trials
Innovative clinical trials that evaluate multiple treatments simultaneously and intended to continue beyond the evaluation of any one treatment, while maximizing statistical and clinical efficiency.
