You likely can't join if

- Subject has received live vaccine within 28 days prior to the first dose of study drug
- The subject has had major surgery per the Investigator within 28 days prior to the first dose of study drug, and the surgical wound is not adequately healed. A diagnostic or research biopsy does not exclude subjects from enrollment. Placement of a vascular access device such as a Port-A-Cath is not considered major surgery.
- Has uncontrolled intercurrent illness including, but not limited to: a. Uncontrolled diabetes b. New York Heart Association (NYHA) Class 3 or 4 congestive heart failure c. Unstable angina, arrhythmia, or myocardial infarction within 6 months prior to screening d. Poorly controlled hypertension, defined as a blood pressure consistently above 160/90 mmHg despite optimal medical management e. Uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage more than once every 28 days. Indwelling drainage catheters (e.g., PleurX®) are allowed f. Active or chronic viral hepatitis B or C infection g. Uncontrolled thyroid disease h. Active infection requiring systemic therapy; subjects receiving ongoing systemic antibiotic, antiviral or antifungal therapy for maintenance should be discussed with the medical monitor prior to screening and enrollment
- History of SJS, Toxic epidermal necrolysis (TEN), or drug reaction with eosinophilia and systemic symptoms (DRESS)
- History of autoimmune disease including but not limited to rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease, non-infectious pneumonitis, interstitial lung disease (ILD), requiring systemic treatment that required systemic steroids or immunosuppressive agents within the last 2 years. Subjects with findings consistent with active autoimmune disease on screening evaluation (computed tomography [CT] showing pneumonitis or ILD, physical examination findings) are not eligible. NOTE: History of vitiligo, autoimmune thyroiditis, or mild psoriasis are allowed.
