History of any of the following toxicities associated with a prior immunotherapy:

Grade >= 3 immune mediated adverse event that was considered related to previous immunotherapy and required immune suppressive therapy. It is acceptable to allow patients with Grade 3 ophthalmologic immune-mediated events that improved to Grade 1 within 2 weeks after topical therapy only, and patients with Grade 3 endocrine immune-mediated events that did not experience symptoms lasting > 6 weeks and are not requiring > 7.5mg prednisone or equivalent per day.
Immune mediated adverse event that was considered related to previous immunotherapy and is still > grade 1 with immune suppressive therapy
• Any active immune-mediated adverse events requiring ongoing immune suppressive therapy (hormone replacement therapy is permitted).
Patients with known active central nervous system (CNS) lesions are excluded (i.e., those with radiographically unstable, symptomatic lesions). However, patients treated with stereotactic therapy or surgery are eligible if they remain without evidence of disease progression in the brain for 14 days.
