• Clinically significant uncontrolled illness
• Active infection requiring antibiotics
• Research participants who have tested human immunodeficiency virus (HIV) positive, or have active hepatitis B or C infection based on testing performed within 4 weeks of enrollment
• Active viral hepatitis
• Any other condition that would, in the Investigator's judgment, contraindicate the subject's participation in the clinical study due to safety concerns with clinical study procedures

Egyéb

• Documented informed consent of the participant and/or legally authorized representative
  • Assent, when appropriate, will be obtained per institutional guidelines
  • For research participants who do not speak English, a short form consent may be used with a City of Hope (COH) certified interpreter/translator to proceed with screening, while the request for a translated full consent is processed
