Summary
Background : Monoclonal antibodies to the pro‐inflammatory cytokine tumour necrosis factor‐α have shown efficacy in treating Crohn's disease, but can be immunogenic. Soluble tumour necrosis factor‐binding proteins are being studied as potential alternative anti‐tumour necrosis factor agents in Crohn's disease.
Aim : To investigate the safety and efficacy of onercept, a recombinant form of the natural human soluble p55 tumour necrosis factor receptor, in the treatment of patients with active Crohn's disease.
Methods : In a pilot study, 12 patients with active Crohn's disease were randomized to receive onercept at either 11.7 or 50 mg three times weekly for 2 weeks. Patients were followed up for 6 months after the end of treatment.
Results : The Crohn's disease activity index decreased rapidly during treatment in both groups. Seven responses (Crohn's disease activity index decrease of 100 points) were observed over the first 6 weeks of the study, including five remissions (Crohn's disease activity index decrease of 150 points). Improvement was sustained for 2–4 months after stopping treatment. Treatment was well tolerated. No patients developed antibodies to onercept.
Conclusions : Neutralizing the activity of tumour necrosis factor‐α with its soluble p55 receptor may be valuable in the treatment of patients with Crohn's disease. Larger placebo‐controlled trials are indicated.
