Efficacy of Alicaforsen in Pouchitis Patients Who Have Failed to Respond to at Least One Course of Antibiotics

Phase 3
Completed
Conditions
Pouchitis
Interventions
Drug: Placebo
Registration Number
NCT02525523
Lead Sponsor
Atlantic Pharmaceuticals Ltd
Brief Summary

A Phase III, multi-centre, double-blind randomised controlled trial in subjects with chronic antibiotic refractory pouchitis.

Subjects will undertake a \<2 week screening period to provide baseline data and be assessed for eligibility. At the Baseline visit (Day 1) eligible subjects will be randomised on a 1:1 basis to either a) 240 mg alicaforsen enema or b) matching placebo.

Study drug will be administered once nightly (on going to bed) up to and including week 6. Following the Day 1 Visit, subjects will return to the clinic for safety and efficacy assessments at Week 3, 6, 10, 18 and 26.

Subjects may receive certain permitted medications as per Entry Criteria, which must remain at stable doses throughout the trial. Introduction of any new medication for pouchitis, or a dose change to an existing concomitant medication for pouchitis, other than those detailed in the protocol, will not be permitted.

Clinical symptoms associated with pouchitis will be recorded daily by the patient in a diary card.

Subjects will undergo endoscopic examination of their pouch (during Screening, and at Weeks 6 and 10). Where technically feasible, each endoscopy will provide at least one biopsy sample for histopathology.

In addition to endoscopic, histopathologic and symptomatic assessments, Quality of Life will be assessed.

Bloods for routine assessment, including haematology and biochemistry will be taken. Bloods and stool samples will be collected to evaluate relevant biomarkers.

Primary Outcome Measures
NameTimeMethod
Proportion of Patients With Endoscopic RemissionWeek 10

The group of patients with an improvement in their endoscopic score between screening and week 10 as shown by an reduced modified MAYO score. Remission is defined as absence of friability and ulceration, represented by a score of ≤1.

Proportion of Patients With a Reduction in Relative Stool FrequencyWeek 10

Group of patients with a lowering of stool frequency from baseline to week 10, where the subject's stool frequency is represented by a MAYO subscore of ≤1 at week 10.
