• •a) Subjects with known or suspected CNS metastases or with the CNS as the only site of active disease are excluded with the following exceptions: i. Subjects with controlled brain metastases will be allowed to enroll. Controlled brain metastases are defined as those with no radiographic progression for at least 4 weeks after radiation and/or surgical treatment at the time of consent. Subjects must have been off of steroids for at least 2 weeks prior to informed consent, and have no new or progressive neurological signs and symptoms.
• •2. Medical History and Concurrent Diseases
• •1. Subjects with an active, known or suspected autoimmune disease. Subjects with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.
• •2. Prior malignancy active within the previous 3 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, or carcinoma in situ of the prostate, cervix, or breast.
• •3. A known or underlying medical condition that, in the opinion of the Investigator or Sponsor, could make the administration of study drug hazardous to the subject or could adversely affect the ability of the subject to comply with or tolerate study
• •4. Requirement for daily supplemental oxygen
• •5. The patient has a history of pneumonitis, organ transplant, human immunodeficiency virus positive, active hepatitis B or hepatitis C
• •6. Any of the following medications or procedures:
• •i. Within 2 weeks prior to time of treatment initiation: I. Systemic or topical corticosteroids at immunosuppressive doses (\> 10 mg/day of prednisone or equivalent). Inhaled or topical steroids, and adrenal replacement steroid doses \> 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease.
• •II. Palliative radiation or gamma knife radiosurgery ii. Within 4 weeks prior to time of treatment initiation: I. Any anticancer drug II. Any vaccine or adjuvant III. Allergen hyposensitization therapy IV. Growth factors V. Major surgery, or the subject has not recovered from surgery at the time of treatment initiation
• •g) The subject has not recovered to grade 0-1 from adverse events due to prior chemotherapy, radioactive or biological cancer therapy
• •h) History of life-threatening or severe immune related adverse events on treatment with another immunotherapy and is considered to be at risk of not recovering
• •i) The subject is expected to require any other form of systemic antineoplastic therapy while receiving the treatment
• •j) Any condition that will interfere with patient compliance or safety (including but not limited to psychiatric or substance abuse disorders)

• •l) Significant medical disorder according to investigator; e.g. severe asthma or chronic obstructive lung disease, dysregulated heart disease or dysregulated diabetes mellitus
• •m) Concurrent treatment with other experimental drugs
• •n) Severe allergy or anaphylactic reactions earlier in life
