| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| • Assessment of efficacy of QAX576 to induce complete closure for at least 4 weeks of all perianal fistulas in patients suffering from Crohn's
 disease by: clinical observation and cutaneous photodocumentation [
 Time Frame: 52 weeks ] [ Designated as safety issue: No ]
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| • Assessment of safety and tolerability of QAX576 in patients suffering from Crohn's disease as measured by lab assessments, ECG, physical
 exam etc [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]
 Other secondary objectives are listed in the clinical study protocol.

| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| • At least one draining enterocutaneous perianal fistula • Diagnosis of Crohn's disease (CD) must have been established for at
 least 6 months
 • At least one ineffective fistula treatment (but no previously failed anti-
 TNFα (tumour necrosis factor) antibody treatment)
 • Patients should not suffer from any other health problems that may
 jeopardize their participation in the study.
 Additional details and inclusion criteria are available in the clinical study
 protocol.
 |  | 
| E.4 | Principal exclusion criteria | 
| • Current or recent (within 30 days of enrollment, or 5 half-lives of the compound, whichever is longer) use of anti-TNFα antibody treatment
 • Active Crohn's disease
 • Recent or pending abdominal or ano-rectal surgery, particularly
 presence of stricture, or abscess, or retention for which surgery might be indicated
 • Previously failed anti-TNFα antibody treatment
 • Intercurrent bacterial or viral (intestinal) infection (serologically or
 microbiologically confirmed)
 Additional details and exclusion criteria are available in the clinical study
 protocol.
