TDM-based Infliximab Treatment for Active Perianal Fistulizing Crohn's Disease

Crohn Disease Clinical Trial

Official title: Efficacy of Infliximab Treatment Based on TDM (Therapeutic Drug Monitoring) in Adult Patients With Active Perianal Fistulizing Crohn's Disease

Status Recruiting

Clinical Trial Summary

This study will compare the efficacy and safety of TDM (therapeutic drug monitoring)-based infliximab (CT-P13, RemsimaTM) intravenous therapy compared with the standard infliximab (RemsimaTM) intravenous therapy for patients with active perianal fistulzing Crohn's disease.

Clinical Trial Description

The TDM-based group: At week 0,2, and 6, infliximab (RemsimaTM) is intravenously administered at a dose of 5 mg/kg. From week 14 to 46 (at week 14, 22, 30, 38, and 46), infliximab dose can be increased to 10 mg/kg, targeting trough level (TL) of infliximab 10 mcg/mL or over (If TL is 10 mcg/mL or over under treatment with 5 mg/kg infliximab, 5 mg/kg of infliximab is continued. If TL is lower than 10 mcg/mL, infliximab dose is increased to 10 mg/kg). Once infliximab dose was increased to 10 mg/kg, the next doses are fixed to 10 mg/kg. The standard group: Infliximab (RemsimaTM) is intravenously administered at a dose of 5 mg/kg at week 0, 2, 6, 14, 22, 30, 38, and 46. Therapeutic dose monitoring (TDM, checking trough levels of infliximab) is performed at week 14, 22, 30, 38, and 46, but TDM results are not reflected in determining doses of infliximab. The co-primary endpoints of the study will be 1) Clinical remission (both week 50 and week 54), 2) Changes of MAGNIFI-CD (Magnetic Resonance Novel Index for Fistula Imaging in Crohn's Disease) score compared with the baseline score (week 54) ;
