Title: Study on Omega-3 Fatty Acids and Ventricular Arrhythmia, a Parallel, Placebo-Controlled, Double Blind Intervention Study
Brief Summary: The objective of the SOFA trial is to investigate whether supplemental intake of n-3 polyunsaturated fatty acids (n-3 PUFA) from fish oil can reduce the recurrence of life-threatening ventricular arrhythmias in patients with an implantable cardioverter defibrillator (ICD).


Options:
A: Inclusion Criteria:

1. Male or female subject, age 17 or older; country-specific age limitations will be followed
2. Diagnosis of Crohn's disease confirmed by radiological studies or endoscopy or surgical pathology within 36 months prior to randomisation
3. In remission for at least 3 months, but no longer than 12 months; remission being defined as meeting both of the two conditions: (1) clinically in remission with a CDAI of less than 150 and (2) off steroids and/or immunosuppressants for at least 3 months, if remission had been induced with such medications

Exclusion Criteria:

1. Intolerance of omega-3 fatty acids or known allergy to fish or fish products
2. Ongoing CD therapy with: 5-ASA compounds, steroids, immune modifiers, systemic antibiotics, tube feeding, defined formula diets or parenteral nutrition
3. In 3 months prior to randomisation received: systemic steroid therapy, azathioprine, 6-mercaptopurine, methotrexate, cyclosporine, probiotic products or preparations containing fish oil
4. In 12 months prior to randomisation received: biologicals e.g. enbrel, infliximab, mycophenolate, tacrolimus, thalidomide, other immune modifiers and/or investigational products
5. Chronic use of narcotics for pain control (opiates for diarrhoea are acceptable)
6. Documented short bowel syndrome, ostomy
7. Need for bowel surgery for CD, bowel obstruction or resection in past 3 months (a subject who had a bowel resection in the past must have had at least one relapse after the surgery)
8. Malignancy and/or clinically significant impairment in cardiac, liver or renal function, CNS, pulmonary, hematological, immunological, vascular and gastrointestinal disease in addition to CD
9. Known alcoholism or drug abuse

* intake of more than 8g of n-3 fatty acids from fish per month as judged by a fish frequency questionnaire
* pregnant women and women of childbearing potential who do not use adequate contraception
* patients known to have a history of recent drug or alcohol abuse
