Abstract

BACKGROUND:

Adalimumab is effective in inducing remission in patients with active Crohn's disease who had secondary failure to infliximab therapy.

AIM:

To evaluate the efficacy and safety of adalimumab maintenance therapy in Crohn's disease patients who previously responded to infliximab and then lost response or became intolerant.

METHODS:

Twenty-four patients with Crohn's disease were enrolled in a 52-week open-label trial. The patients received a loading dose of adalimumab 80-mg at week 0, and then 40 mg every other week starting at week 2. The primary efficacy measure was clinical remission defined as Crohn's Disease Activity Index score < 150 at week 52.

RESULTS:

Five patients lost response to adalimumab. None of the patients experienced intolerance to adalimumab. Clinical remission rates were higher at weeks 4 (16/24, 67%) and 52 (14/24, 58%) compared with baseline (8/24, 35%) (P=0.043 at week 52). This was accompanied by a decrease in mean C-reactive protein concentration from 31.8 mg/mL at baseline to 9.7 mg/mL at week 52, and 3/4 (75%) patients achieved steroid-free remission. No serious toxicities occurred in the study.

CONCLUSIONS:

Adalimumab is well tolerated and appears to be effective in maintaining clinical remission in patients with Crohn's disease and lost response or intolerance to infliximab.
