• Screening laboratory values within 14 days prior to registration must meet the criteria: WBC ≥ 2,000/μL, Neutrophils ≥ 1,500/μL, Platelets ≥ 100 x103/μL, Hemoglobin > 9.0 g/dL, Serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 40 mL/min, AST/ALT ≤ 3 x ULN, total bilirubin ≤ 1.5 x ULN (except patients with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL), INR ≤ 1.5
• ECOG Performance Status 0, 1 or 2
• Expected life expectancy of ≥ 3 months
• Males and females ≥ 18 years old
• Negative serum pregnancy test within 24 hours prior to the start of study drug for women of childbearing potential (WOCBP)
• Women must not be breastfeeding
• WOCBP must agree to follow instructions for method(s) of contraception, as indicated in the ICF, throughout the study and for 23 weeks after the last dose of investigational drug
• Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception, as indicated in the ICF, throughout the study and for a period of 31 weeks after the last dose of investigational drug. In addition, male patients must be willing to refrain from sperm donation during this time
• Azoospermic males are exempt from contraceptive requirements. WOCBP who are permanently not heterosexually active are also exempt from contraceptive requirements, but must still undergo pregnancy testing as previously described.

• Active infection requiring systemic therapy
• Active, known or suspected autoimmune disease (exceptions: patients with controlled Type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders not requiring systemic treatment).
• Interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity
• Any serious or uncontrolled medical disorders thatmay increase the risk associated with study participation or study drug administration, impair the ability of the patient to receive protocol therapy, or interfere with the interpretation of study results in the opinion of the investigator
• Known substance abuse or psychiatric disorders that would preclude cooperation with tany requirements of the trial
• Legal incapacity or limited legal capacity
