STATIC TRIAL: The STopping Aminosalicylate Therapy in Inactive Crohn’s Disease A Randomized, Open-label, Non-inferiority Trial (STATIC)


PI: Dr. Vipul Jairath, University of Western Ontario



Dr. Gordon Moran – UK
Prof. Silvio Danese – Italy
Prof. A. Dorofeyev – Ukraine



The primary objective is to determine whether withdrawal of aminosalicylates is non-inferior to continuation of aminosalicylates in Crohn’s disease (CD) subjects in remission with regard to a primary endpoint of any CD-related complication (composite of either a CD-related or CD treatment-related surgery, hospitalization, or other complication) within 24 months after enrollment.


Study Design

STATIC is a pragmatic, open-label, non-inferiority trial, in which CD patients in remission will be randomized to either continue aminosalicylate therapy or withdraw treatment.
