- SS is defined as meeting T4 plus B2 criteria; where the biopsy of erythrodermic skin may only reveal suggestive but not diagnostic histopathologic features, the diagnosis may be based on either node biopsy or fulfillment of B2 criteria
- For MF where the histological diagnosis by light microscopic examination is not confirmed, diagnostic criteria that been recommended by the International Society of Cutaneous Lymphomas (ISCL) should be used.

- NOTE: Growth factor is not permitted within 14 days of ANC assessment unless cytopenia is secondary to disease involvement
- With bone marrow involvement: ANC >= 1,000/mm^3 (performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
- NOTE: Growth factor is not permitted within 14 days of ANC assessment unless cytopenia is secondary to disease involvement
- Without bone marrow involvement: Platelets >= 100,000/mm^3 (performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
- NOTE: Platelet transfusions are not permitted within 14 days of platelet assessment unless cytopenia is secondary to disease involvement
- With bone marrow involvement: Platelets >= 75,000/mm3 (performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
- NOTE: Platelet transfusions are not permitted within 14 days of platelet assessment unless cytopenia is secondary to disease involvement
- Total bilirubin =< 1.5 x upper limit of normal (ULN) (unless has Gilbert's disease)(performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
- Aspartate aminotransferase (AST) =< 2.5 x ULN (unless has Gilbert's disease)(performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)

- If not receiving anticoagulants: International normalized ratio (INR) OR prothrombin (PT) =< 1.5 x ULN (performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
- If on anticoagulant therapy: PT must be within therapeutic range of intended use of anticoagulants (performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
- If not receiving anticoagulants: Activated partial thromboplastin time (aPTT) =< 1.5 x ULN (performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
- If on anticoagulant therapy: aPTT must be within therapeutic range of intended use of anticoagulants (performed within 7 days prior to day 1 of protocol therapy unless otherwise stated)
- Hepatitis C virus (HCV)*, active hepatitis B virus (HBV) (surface antigen negative), and syphilis (rapid plasma reagin [RPR])
- If positive, hepatitis C ribonucleic acid (RNA) quantitation must be performed
- Meets other institutional and federal requirements for infectious disease titer requirements
- Note Infectious disease testing to be performed within 28 days prior to day 1 of protocol therapy
- Subjects with MF and a history of staphylococcus colonization are eligible provided they continue to receive stable doses of prophylactic antibiotics
- Women of childbearing potential (WOCBP): negative urine or serum pregnancy test If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
- Agreement by females and males of childbearing potential* to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 3 months after the last dose of protocol therapy
- Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for > 1 year (women only)
