consent.
11. Has received prior radiotherapy within 4 weeks of signing informed consent.
12. Major surgery within 4 weeks before signing informed consent.
13. History or presence of clinically relevant cardiovascular abnormalities such as
uncontrolled hypertension, congestive heart failure NYHA classification of = 3,
unstable angina or poorly controlled arrhythmia as determined by the investigator.
Myocardial infarction within 6 months prior to signing informed consent.
14. Has known history of pneumonitis requiring steroids, or any evidence of active,
non-infectious pneumonitis, or other known interstitial lung disease
15. Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy
(in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of
immunosuppressive therapy within 7 days prior to the first dose of study drug.
16. 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. Topical or inhaled steroids is not considered as systemic
treatment.
17. 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.
18. Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.
19. Any history of or concomitant condition that, in the opinion of the Investigator,
would compromise the patient's ability to comply with the study or interfere with the
evaluation of the efficacy and safety of the test drug
20. Is pregnant or breastfeeding, or expecting to conceive or father children within the
projected duration of the trial, starting with the pre-screening or screening visit
through 120 days after the last dose of trial treatment.
21. Has received a live vaccine within 30 days prior to the first dose of study drug.
Examples of live vaccines include, but are not limited to, the following: measles,
mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus
Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection
are generally killed virus vaccines and are allowed; however, intranasal influenza
vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.
