Specific examples include, but are not limited to, active, non-infectious pneumonitis; uncontrolled ventricular arrhythmia; recent (within 90 days) myocardial infarction; uncontrolled major seizure disorder; unstable spinal cord compression; superior vena cava syndrome; or any psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the study (including obtaining informed consent).
19. Patients with known history of non-infectious pneumonitis that required steroids or has current pneumonitis.

* Interleukins
* Live vaccine Note: Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster, yellow fever, rabies, BCG, and typhoid vaccine. mRNA and adenoviral-based COVID-19 vaccines are considered non-live and are not exclusionary. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed as other killed vaccines, if done at least 2 weeks prior the first dose of study drug; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.
