E.3 | Principal inclusion criteria |
1) Men and women ≥18 years who have given written Informed Consent, 2) Patients with proven UC (according to ECCO consensus definition [28]: UC is a chronic continuous mucosal inflammation of the colon without granulomas on biopsy, affecting the rectum and variable extent of the colon in continuity, which is characterized by a relapsing and remitting course. The diagnoses should be established by a combination of medical history, clinical evalution, and typical endoscopic and histologic findings: a) Medical history and clinical features: loose stools [>6 weeks], episodes of bloody stools and stool urgency, episodes of relapse and periods of remission or an unremitting, continuous course over months; exclusion of infectious colitis [microbiological testing, including Clostridium difficile toxin A and B, Campylobacter spp., E. coli 0157:H7; depending on the medical history fresh, warm stool samples should be tested for amoebae or other parasites], exclusion of drug-induced forms of colitis, b) Endoscopic features, including a colonoscopy with intubation of the terminal ileum: inflammation of the rectum, continuous inflammation to more proximal parts, usually clear demarcation between inflamed and normal areas. Signs of inflammation are vascular congestion or reduction of visible vascular patterns, as well as mucosal friability [after contact with the endoscope]. Moreover, a coarse granular appearance, mucosal erosions or ulcerations may occur, c) Histologic features from multiple mucosal biopsies: absence of granulomas, architectural features [crypt branching, crypt distortion, crypt atrophy or surface irregularity], epithelial cell abnormalities [mucin depletion, Paneth cell metaplasia] and inflammatory signs [increased lamina propria cellularity, basal plasmacytosis, basal lymphoid aggregates, lamina propria eosinophils], Patients may be included into the study if clinician, endoscopist [may be identical with clinician] and pathologist state that the found features are compatible with the diagnosis of UC), 3) Patients naïve to any form of controlled release PC treatment, 4) Active disease course for the last 6 weeks or longer with bloody diarrhea (anamnestic mean number of bloody stool per day ≥4), 5) SCCAI ≥5 and SCCAI subscore for “blood in stool” ≥2 at Baseline Visit (V2), (SCCAI and subscore for blood are calculated as the rounded mean over the last 7 days), 6) Patients with an inadequate response to a treatment with ≥3g of mesalazine per day, over a period of 4 weeks or a documented intolerance to mesalazine, 7) Other drugs for the treatment of UC are allowed, under the following circumstances: - Systemic acting oral steroids are allowed if taken for ≥8 weeks prior to start of the study with a stable dose for ≥4 weeks prior to start of the study, - Immunosuppressive therapy with azathioprine (2-2.5 mg/kg) or 6- mercaptopurine (1-1.5 mg/kg) is allowed, if taken for ≥3 months prior to start of the study, 8) Ability of the patient to understand character and individual consequences of the clinical study, 9) Special requirements for women of childbearing potential: - Negative pregnancy test at V1 and V2, - Use of one highly effective method of contraception for the entire duration of the study, defined as those which result in a low failure rate (i.e. less than 1% per year) when used constantly and correctly such as hormonal contraception, intrauterine contraceptive device or combination of two barrier methods (e.g. condom or diaphragm plus spermicidal cream), - Efficacy of hormonal contraception has to be ensured by following the manufacturers’ recommendations outlined in the respective package insert, especially for cases of diarrhea and vomiting, 10) Drugs applied for the treatment of UC have to be on a stable dosage for at least 4 weeks. Patients cannot be included into the study if the treatment of UC was discontinued within the last 4 weeks prior to the study. |
|
E.4 | Principal exclusion criteria |
1) Toxic megacolon or fulminant colitis, 2) No current treatment for UC with either highdose 5-ASA (at least 3g/d) or oral steroids or immunosuppressants or combinations 3) Concomitant therapy as following: a) Therapy with cyclosporine, tacrolimus, methotrexate, or tumor necrosis- (TNF)-alpha-antagonists within 3 months prior to study entry, b) Current treatment with opiates or loperamide, c) Current antibiotic treatment, 4) Rectal applications of aminosalicylates, budesonide, or other steroids within 4 weeks prior to study entry, 5) Oral application of topically acting steroids, e.g. budesonide, within 4 weeks prior to study start, 6) Treatment with other IMP within 3 months prior to study entry, 7) Condition after complete or partial resection of the colon, 8) Infectious colitis, including cytomegalovirus or Clostridium difficile induced colitis, 9) Crohn’s disease, 10) Colitis due to other reasons than UC like known diverticulitis, radiation colitis, ischemic colitis, microscopic colitis, or indeterminate colitis, 11) Malabsorption syndromes, chronic pancreatitis, 12) Celiac disease, 13) Acute bleeding hemorrhoids, 14) Other inflammatory or bleeding disorders of the gastrointestinal tract, or diseases that may cause diarrhea or gastrointestinal bleeding, 15) Pregnant or nursing women, 16) Known drug, alcohol, or medication abuse during the last 2 years prior to start of the study, 17) Any other uncontrolled systemic diseases (e.g. cardiac, renal, pulmonary, or hepatic) or severe chronic diseases (e.g. malignant tumor, HIV infection, high-grade intraepithelial neoplasia), 18) Ulcerative proctitis with a disease extent <10 cm, 19) Participation in another clinical trial within the last 30 days, simultaneous participation in another clinical trial, or previous participation in this trial. |
