  • Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
  • Adequately treated cervical carcinoma in situ without evidence of disease

Those who are hepatitis B surface antigen (HbsAg) positive or hepatitis B PCR positive will be excluded. Subjects who are hepatitis C antibody positive will need to have a negative PCR result. Those who are hepatitis C PCR positive will be excluded. Subjects with a history of Hepatitis C who received antiviral treatment are eligible as long as PCR is negative
