Symptomatic interstitial lung disease or active infection/non-infectious pneumonia; 4. Patients have risk factors for intestinal perforation: active diverticulitis, intra-abdominal abscess, gastrointestinal (GI) obstruction, abdominal cancer or other known risk factors for intestinal perforation; 5.
