NOTE: Inhaled, intranasal, intra-articular, or topical steroids are permitted. Adrenal replacement steroid doses \> 10 mg daily prednisone equivalent are permitted in the absence of active autoimmune disease. Transient short-term use of systemic corticosteroids for allergic conditions (eg, contrast allergy) is also allowed.
• •* Malabsorption syndrome.
• •* Serious non-healing wound/ulcer/bone fracture. NOTE: Non-healing wounds or ulcers are permitted if due to tumor- associated skin lesions.
