Detailed Description
-----------------
Objectives: The study objective is to demonstrate that the UVADEX® Sterile Solution formulation of methoxsalen used in conjunction with the UVAR XTS Photopheresis System can have a clinical effect on the skin manifestations of CTCL (mycosis fungoides) in early stage disease. Methodology: Single-arm, open-label treatment using UVAR XTS Photopheresis System. Treatment consists of two photopheresis treatments on successive days every 4 weeks for six months. Those patients completing the first 6-month period may be continued on photopheresis for a 6-month follow-up period. Patients who do not respond to photopheresis therapy after 6 months may have concurrent therapy with low dose bexarotene and interferon added as outlined in the protocol. Number of Patients (Planned and Analyzed): The study plan is for a minimum of 50 patients Diagnosis and Main Criteria for Inclusion: Male or female patients with CTCL diagnosis of stage IA, IB or IIA with measurable skin lesions (patches or plaques) and a minor blood abnormality. Patients must be refractory to at least one treatment for early stage CTCL such as PUVA, Electron beam, oral steroids, high potency topical steroid, topical nitrogen mustard, methotrexate, interferon, or bexarotene. Test Product, Dose and Mode of Administration, Batch or Lot Number: UVADEX liquid methoxsalen 20mcg/mL in conjunction with the UVAR XTS Photopheresis System. UVADEX is injected into the photoactivation bag during photopheresis therapy in accordance with the approved drug package insert and UVAR XTS operator's manual. UVADEX dose is less than 200mcg per treatment. Duration of Treatment: The study will consist of 2 treatment periods, a 6-month initial period and a 6-month follow-up period where photopheresis therapy may continue. Criteria for Evaluation: Efficacy: The primary endpoint will be the overall response based on skin-weighted assessment. Secondary endpoints will also include time to response, duration of response, and a Quality of Life  assessment. The size and number of lymph nodes and flow cytometry analyses will also be considered. Experienced skin observers will perform skin scores on each patient at enrollment. Skin scores will be recorded as the percentage of the patient's body involved with patch or plaque lesions. A successful response to therapy will be patients who have a greater than 50% improvement in skin involvement (PR) or complete skin improvement (CR) without worsening in nodes, blood or visceral organs. Patients with 25%-50% improvement will be considered as minor response (MR), + or - 25% will be SD, and PD will be defined as 25% worsening from baseline. Safety: Safety is assessed by the incidence and intensity of adverse events, whether clinical or based on laboratory results. Statistical Methods: The primary endpoint will be the proportion of patients who have CR and PR of their skin lesions.

Eligibility Criteria
-----------------
Inclusion Criteria: Patients are to be greater than 40 kg body weight. Patients must have adequate veins to provide intravenous access. Women who are not pregnant, lactating, or of childbearing potential. Lack of childbearing potential was defined as: Being post-menopausal Being surgically sterile Practicing contraception Patients with childbearing potential had to have a negative serum human chorionic gonadotropin (HCG) upon entrance into the study. Patients must be willing to adhere to the protocol, and sign an Informed Patient Consent Form prior to entry into the study. Patients must not be on any other investigational device/drug treatment. Patients with the diagnosis of mycosis fungoides (MF) including a skin biopsy consistent with MF (atypical epidermotrophic or folliculocentric T-cells). Appropriate staging as IA, IB or IIA : T1 or T2 (patches or plaques) with measurable lesions. IA patients must show evidence of a minor blood abnormality by morphology or laboratory assessment. For IIA patients - clinically significant nodes (1.5 cm) must have lymph node biopsy showing dermatopathic nodes or no involvement. Patients must be willing and able to discontinue concomitant medications for MF. Patients currently taking the following drugs must discontinue medication prior to enrollment in the trial: Psoralens and ultraviolet A (PUVA) or ultraviolet B (UVB) therapy - 4 weeks Topical nitrogen mustard or other topical chemotherapy - 4 weeks Bexarotene capsules or other systemic biologic agent - 3 weeks washout High dose topical steroids, topical retinoids or immunotherapy - 2 week washout with 1% topical hydrocortisone Oral steroids above 10 mg - 30 day washout, unless patient has Addison's disease or adrenal insufficiency Patients must be refractory to at least one of the standard therapies used to treat Stage IA, IB or IIA CTCL such as oral steroids, high-dose topical steroids, mechlorethamine (HN2), bexarotene, PUVA therapy, electron beam radiation, biological response or oral methotrexate. Patients must abstain from therapeutic sunbathing, tanning beds, etc. for the duration of the study. Exclusion Criteria: Patients who have MF (T3 cutaneous tumors or T4 exfoliative erythroderma) Stage IIB - IVB, ie. no pathological node or visceral involvement. Patients who are unable to tolerate extracorporeal volume loss (e.g., severe cardiac disease or severe anemia or weight < 40 kg). Patients with recent (within three months) deterioration of renal function who have a serum creatinine level greater than 3.0 mg/dL. Patients with lipemic plasma > 500 ng/dL or uncontrolled diabetes. Patients with a history of liver damage (2.5 x normal ALT, AST) or porphyria. Patients with positive tests for HIV antibody, hepatitis C virus (HCV) antibody or hepatitis B surface antigen. Patients on oral prednisone therapy or full body or high potency topical steroids. Women who are pregnant or nursing a child. Patients with severe emotional, behavioral or psychiatric problems that, in the opinion of the investigator, would result in poor compliance with the treatment regimen. Patients who exhibit idiosyncratic or hypersensitivity reactions to 8-methoxypsoralen compounds, heparin, or citrate. Patients with previous exposure to photopheresis therapy. Patients who use tanning beds or are receiving phototherapy.
