BACKGROUND: The risk:benefit ratio of concomitant use of thiopurines with scheduled adalimumab (ADA) maintenance therapy for Crohn's disease is controversial. The aim of this study is to identify the influence of withdrawal of thiopurines in patients in remission with combination therapy in an open-label, randomised, controlled trial (DIAMOND2; UMIN000009596).
METHODS: Patients in corticosteroid-free clinical remission (CFCR) for ≥ 6 months with ADA (40 mg, s.c., every other week) scheduled maintenance combined with thiopurines were randomised into two groups, "continue" (Con) or "discontinue" (Dis) group of thiopurines, whereas all other patients kept receiving scheduled ADA maintenance therapy for 52 weeks. The primary endpoint was the proportion of patients in CFCR at week 52. Secondary endpoints were endoscopic remission (ER), trough levels of ADA in serum, and safety.
RESULTS: Fifty patients were randomised to Con or Dis groups. Characteristics of patients were not significantly different between the groups. CFCR and ER prevalence at week 52 were not significantly different between groups (log rank, P = 0.704, P = 1.000, respectively). Trough levels of ADA were not significantly different between groups (P = 0.515). The proportion of patients with AAA positivity at week 52 was not significantly different (P = 0.437). ER at week 0 was involved in ER and triple remission at week 52. No serious adverse effects were observed in either group.
CONCLUSION: Continuation of thiopurines > 6 months offers no clear benefit over scheduled ADA monotherapy. CFCR, ER, and ADA trough level at week 52 were not significantly different between groups. ER at week 0 may be involved in better long-term clinical outcomes.
