3. All other immunotherapies, including PD-(L)1-targeted immunotherapies (e.g.,
atezolizumab, pembrolizumab): 21 days
4. All other systemic therapies: 14 days
5. Radiotherapy: 14 days (excepting palliative radiotherapy to a limited field
[e.g., for a focally painful tumor mass], which may be administered within 14
days provided there are no ongoing related Grade 2 or higher toxicities)
Medical Conditions and Concomitant Medications
3. Systemic treatment with steroids or any other immunosuppressive drug use within 2
weeks of the planned first dose of program intervention, with the following
exceptions:
1. Treatment for well-controlled and asymptomatic adrenal insufficiency is
permitted, but replacement dosing is limited to prednisone = 12 mg daily or the
equivalent.
2. Local steroid therapies (e.g., optic, ophthalmic, intra- articular, or inhaled

3. Premedication for allergy to contrast reagent.
4. Steroids for management of CNS metastases > 2 weeks prior to the planned first
dose of program intervention.
4. Any relevant medical condition, which in the opinion of the treating physician, would
prevent the participant enrolling into the Program due to concerns related to safety,
compliance with procedures, or interpretation of program results.
5. Chronic viral infections as indicated below. NOTE: Testing for hepatitis C virus (HCV)
status prior to enrollment is not necessary unless clinically indicated.
1. Known history of human immunodeficiency virus (HIV) infection.
2. Known HBV infection, unless on stable anti-viral therapy for > 4 weeks prior to
the planned first dose of program intervention and viral load confirmed as
undetectable during Screening.
3. Known HCV infection, unless the participant has received curative treatment and
viral load was confirmed as undetectable during Screening.
Diagnostic Assessments
6. Participant with an out-of-range Screening laboratory values defined as shown below.
NOTE: Hematology evaluations must be performed = 7 days from any blood or blood
product transfusion and = 14 days from any dose of hematologic growth factor.
1. Creatinine clearance (calculated using Cockcroft-Gault formula, or measured) < 30
mL/minute
2. Total bilirubin > 1.5 × ULN, except for patients with Gilbert's syndrome who are
excluded if total bilirubin > 3.0 × ULN or direct bilirubin > 1.5 × ULN
3. Alanine aminotransferase > 5 × ULN
4. Aspartate aminotransferase > 5 × ULN
5. Platelet count < 50 × 109/L
6. Hemoglobin < 8 g/dL
7. Clinically significant cardiac disease or impaired cardiac function, including any of
the following:
1. Congestive heart failure (New York Heart Association Class = 3)
2. Uncontrolled hypertension defined as systolic blood pressure [BP] > 160 mmHg or
diastolic BP > 110 mmHg with the following requirements:
1. If initial measurement is elevated, additional assessments should be taken where
each assessment is the mean value of 3 measurements taken at least 5 minutes
apart.
2. Eligibility is based on the average of at least 2 assessments taken at least 1
hour apart.
3. Acute myocardial infarction or unstable angina pectoris < 6 months prior to the
planned first dose of program intervention
