4.Subjects with CRP levels above 5 mg/L at screening or any time between
screening to baseline, including at baseline OR documented endoscopic
evidence of mucosal ulcerations within 4 weeks prior to baseline.

14.Subjects treated with more than 20mg/day of prednisolone (or equivalent) or budesonide > 6mg/day for CD at baseline, or whose corticosteroid dosage regimen is not stable for at least 2 weeks prior to baseline.
15.Subjects treated with 5-ASA who are not on stable dose for at least 2 weeks prior to screening.
16.Subjects treated with antibiotics for CD at screening who are not on a stable dose for at least 2 weeks prior to screening.
17.Subjects treated with 6-MP, AZA or MTX, who have initiated this treatment within 12 weeks prior to screening or who are not on a stable dose for at least 6 weeks prior to screening.
18.Subjects treated with Anti-TNFs within 4 weeks prior to screening.

24.Women who are pregnant or nursing at the time of screening, or who intend to be during the study period.
25.Women of child-bearing potential who do not practice an acceptable method of birth control.
26.A known drug hypersensitivity that would preclude administration of laquinimod, such as hypersensitivity to: mannitol, meglumine or sodium stearyl fumarate.
27.Subjects unable to comply with the planned schedule of study visits and study procedures.
