P374 Safety and drug survival of methotrexate versus tioguanine after failure of conventional thiopurines in patients with Crohn’s disease

Background Both methotrexate (MTX) and tioguanine (TG) can be considered as viable treatment options before initiating biological therapy following failure of conventional thiopurines for Crohn’s disease. It is unclear how safety and effectiveness compare for both therapies. This study aimed to compare tolerability and drug survival of MTX and TG therapy after failure of conventional thiopurines in patients with Crohn′s disease. Methods We...
