limited to, myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus
erythematosus, rheumatoid arthritis, inflammatory bowel disease, antiphospholipid

excluded) are eligible for the study provided all of following conditions are
met:
1. Rash must cover < 10% of body surface area,
2. Disease is well controlled at baseline and requires only low-potency topical
corticosteroids,
3. No occurrence of acute exacerbations of the underlying condition requiring
psoralen plus ultraviolet A radiation, methotrexate, retinoids, biologic
agents, oral calcineurin inhibitors, or high potency or oral corticosteroids
within the previous 12 months,
14. Prior allogeneic bone marrow transplantation or prior solid organ transplantation
15. History of severe allergic, anaphylactic, or other hypersensitivity reactions to

pneumonitis in the radiation field fibrosis is permitted), or evidence of active
pneumonitis requiring a systemic treatment with 28 days before the planned start of
study therapy
