E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the efficacy of subcutaneous certolizumab pegol 400 mg in patients suffering from Crohn's disease at week 0, 2, 4 and 8. efficacy will be assessed using the CDEIS (Crohn's Disease Endoscopic Index of Severity) score at week 10 compared to baseline. |
|
E.2.2 | Secondary objectives of the trial |
To assess the efficacy of subcutaneous certolizumab pegol 400 mg in patients suffering from Crohn's disease evaluated as the proportion of patients achieving mucosal healing (defined as complete absence of mucosal ulcerations) at week 10.
To assess the clinical efficacy of subcutaneous certolizumab pegol 400 mg in patients suffering form Crohn's disease evaluated as improvement from the baseline in the mean histological Crohn's disease score (9) (combines active inflammatory changes: infiltration of mononuclear cells, polymorphonuclear cells, presence of erosions and/or ulcers, and chronic architectural changes) at week 10.
To assess the clinical efficacy of subcutaneous certolizumab pegol 400 mg in patients suffering from Crohn's disease evaluated as proportion of patients achieving clinical response (defined as a decrease of at least 100 points on CDAI score) at week 10. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Patients suffering from active Crohn's disease with CDAI NLT 220 and < 450 (scored over the 7 days prior to the first study treatment dose) and at least two segments with endoscopic ulcerative lesions with CDEIS NLT 8 at the baseline. - Adult men and women NLT 18 years of age. - Patients able to understand the information provided to them and give written informed consent. - Patients able to understand and complete self-administered questionnaires. - Female patients either postmenopausal for at one year, surgically incapable of childbearing, or effectively practising an acceptable method of contraception (oral or parenteral hormonal contraceptives; intrauterine device; barrier or spermicide). Abstinence is not an acceptable method. Patients must agree to continue to use adequate contraception during the study and for 12 weeks after the last dose of certolizumab pegol. - Patient having a social security system. - Concomitant medication; (6-ASA or antibiotics (stable for 4 weeks prior to screening), corticosteroids equivalent to or less than 30mg prednisolone per day (stable dose for 2 weeks), azathioprine and 6-mercaptopurine or methotrexate (stabel dose for 8 weeks) are allowed at baseline and during the study. |
|
E.4 | Principal exclusion criteria |
Crohn's disease related: - Symptomatic obstructive intestinal strictures. - Bowel resection within 4 weeks of starting the study medication. - Proctocolectomy or total colectomy. - Fistula present at screening. - Current total parental nutrition. - Short bowel syndrome. - Positive stool laboratory results for enteric pathogens. - Antibiotic treatment for non-Crohn's related infections within 3 weeks prior to screening.
Medical History Exclusion: - Ulcerative colitis - lactating and/or pregnay female patients. - Female patients of childbearing age who are NOT practicing (in the Investigator's opinion) effective birth control. All female patients must test negative on a serum pregnancy test before study entry and negative on urine testing immediately before every certolizumab pegol afministration. - A history of chronic infection, recent serious or life-threatening infection (within 6 months, including herpes zoster), or any current sign or symptom that may indicate an infection (e.g. fever, cough). - A history of tuberculosis or positive chest X-ray for tuberculosis or positive (defined as positive induration more than or equal to) PPD skin test. Patient with a positive PPD skin test associated with previous vaccination where there is no clinical or radiographic suspicion of TB may be enrolled at the discretion of the Investigator. Consideration should be givn to the fact that a positive PPD skin test with prior vaccination does not include latent TB. - Patients at a high risk of infection (e.g. leg ulcers, indwelling urinary catheter and persistent or recurrent chest infections). - Patients with known concurrent viral hepatitis or known positivity to HBe-Ag, HBV DNA, HBV DNA polymerase, HCV RNA, anti HCV antibodies. - Receipt of any vaccination (live or attenuated) within 8 weeks prior to Baseline (Influenza and Pneumococcal vaccines are allowed). - Concurrent malignancy or a history of malignancy (other than carcinoma of the cervix or basal cell carcinoma successfully treated more than five years prior to screening. Current or recent history of severe, progressive, and/or uncontrolled renal, hepatic, haematological, gastointestinal, endocrine, pulmonary, cardiac, neurological, or celebral disease. Known human immunodeficiency virus (HIV) infection. - New York Heart Association (NYHA) class III-IV congestive heart failure requiring medical treatment. - A histiry of an adverse reaction to polyethylene glycol (PEG) or a protein medicinal product. - Any other condition, which in the Investigator's judgement would make the patient unsuitable for inclusion in the study. - History of drug or alcohol abuse in the prior year. - Any modifications in the concomittant treatments (dose and/or frequency), other that those described above will be considered as non authorized concomittant medication.
Previous clinical trials and previous biological therapy exclusion: - Previous treatment with a biological therapy for CD that resulted in a severe hypersensivity reaction, an anaphylactic reaction or lack or response. - Treatment with infliximab / adalimumab within 12 weeks prior to Visit 2 - Previous treatment with natalizumab - Previous treatment with certolizumab pegol - Other biological therapy throughout the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy variable is the mean change from the baseline of CDEIS score at week 10. [The mean of primary efficacy endpoint, the change at week 10 from baseline in the CDEIS score, will be presented witha 95% confidence interval. It will be assumed that the endpoint is normally distributed for the purposes of the confidence interval calculation. The distribution of the endpoint will be plotted as a histogram and if it is found that the data do not appear to be normal then alternate methods will be used. These could include transforming the original data or a non-parametric 95% confidence interval around the median. Further some prognostic factors will also be investigated]. |
