To evaluate the efficacy and safety of ustekinumab in the treatment of chronic antibiotic refractory and relapsing pouchitis.
This study is a Belgian prospective open label multicenter study to evaluate the efficacy and safety of ustekinumab in the treatment of relapsing or chronic antibiotic refractory pouchitis during a 48-week treatment period. Twenty subjects with a RPC and IPAA for UC who have developed relapsing or chronic antibiotic refractory pouchitis will be enrolled.
All patients will receive intravenously (IV) ustekinumab ~6mg/kg at baseline and subcutaneously (SC) ustekinumab 90mg every 8 weeks thereafter until Week 48. All subjects will receive concomitant antibiotic treatment with ciprofloxacin or metronidazole from baseline through Week 4. Intravenous induction doses will be 260mg for patients <55kg, 390mg for patients between 55 and 85kg, and 520mg for patients with a body weight >85 kg.
Clinical and biochemical evaluation will be planned every 8 weeks. Efficacy will be assessed at Week 16 and Week 48 using mPDAI and PDAI scores, therefor a pouchoscopy with biopsy sampling will be performed. Patients who do not achieve partial response (reduction of mPDAI score by 2 points from baseline) at Week 16 will be discontinued.
