Brief Summary:
The purpose of this study is to determine if cobitolimod (former called Kappaproct®) is effective in the treatment of chronic active ulcerative colitis patients not responding to available therapy.
Detailed Description:
The study is a placebo-controlled, double-blind, randomised study to assess the efficacy and safety of cobitolimod as an add-on to current practice in treatment refractory ulcerative colitis patients. The study population will be chronic active ulcerative colitis patients who are no longer responding adequately to standard therapies and who are potential candidates for colectomy. Cobitolimod/placebo will be add-on treatment allowing all included patients to be on concomitant medication, as well as mandatory steroids at inclusion, throughout the study.
Cobitolimod (DIMS0150) is a modified single strand DNA-based synthetic oligodeoxyribonucleotide of 19 bases in length. The drug functions as an immunomodulatory agent by targeting the Toll-like receptor 9 (TLR9) present in immune cells (i.e., B-cells and pDCs) residing in high abundance on mucosal surfaces, such as colonic and nasal mucosa. The mucosa of the colon and rectum of patients with ulcerative colitis contains active immune cells, which produce damage to the tissue. The activation of these cells by cobitolimod results in the systemic release of specific cytokines (e.g., IL-10 and type I interferons) and chemokines which are believed to be important factors for the clinical effect cobitolimod of cobitolimod. 131 eligible patients was randomly assigned in a 2:1 allocation to receive two single rectal doses of cobitolimod at 30 mg each, or placebo, at week 0 and 4.
The primary endpoint is the induction of clinical remission at week 12 and patients will be continuously followed for efficacy and safety until 12 months after the first dose. Secondary endpoints include the induction of symptomatic remission (number of stools and blood in stools), induction of registration remission (clinical and endoscopic remission) and rate of colectomy.
