EXCLUSION CRITERIA:

The subject must be excluded from participating in the trial if the subject:

• Has known malignant central nervous system (CNS) involvement.
• Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
• Has history of (non-infectious) pneumonitis that required steroids, evidence of interstitial lung disease or active, non-infectious pneumonitis.
• Has an active infection requiring intravenous systemic therapy.
• Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
