简要总结
The purpose of this study is to determine the optimal dose of subcutaneous CAMPATH when used in combination with rituximab for patients with relapsing or refractory, low-grade or follicular, CD-20-positive, B-Cell non-Hodgkin's Lymphoma. Safety will be the primary objective of phase I, while the primary objective of phase II will be to determine overall response.
详细描述
This study is being conducted in 2 parts. Phase I will involve dose escalation of subcutaneous CAMPATH (SQ) given 3 times per week in combination with weekly doses of rituximab (375mg/m2) for a maximum of 8 weeks in order to determine the maximum tolerated dose (MTD). In Phase II patients will be treated with SQ CAMPATH at the MTD plus weekly rituximab (375mg/m2)for a maximum of 8 weeks with primary objective of defining Overall Response (OR) to this combination.

入选标准
- •For the Phase I portion of the study, patients must have pathologically confirmed diagnosis of low-grade or follicular, CD20-positive, B-cell, non-Hodgkin's lymphoma that has relapsed or is refractory. For the Phase II portion of the study, patients must have a pathologically confirmed diagnosis of low-grade or follicular, CD20-positive, B-cell, non-Hodgkin's lymphoma (Follicular, predominantly small cleaved or follicular, mixed small cleaved and large cell, International Working Formulation classification B or C or REAL classification follicular center grade 1,2) that has relapsed or is refractory.
- •Previously treated with at least one anti-cancer regimen for NHL

- •Life expectancy of at least 12 weeks
- •WHO performance status or 0 or 1
- •Adequate marrow and organ function (as defined in the protocol)
- •Completed major surgery, radiotherapy, chemotherapy, immunotherapy or biotherapy/targeted therapies at least 4 weeks prior to study entry (6 weeks if treated with a nitrosourea or mitomycin). Patients must have recovered from all prior treatment toxicity to Grade 1 or less, exclusive of alopecia.

- •Use of investigational agents within 30 days of study enrollment
- •Past history of anaphylaxis following exposure to humanized monoclonal antibodies
- •Known, active, infection, including HIV positive
- •Diagnosis of another malignancy within the previous five (5) years, unless the probability of recurrence of the prior malignancy is < 5%. Patients with curatively treated early stage squamous cell carcinoma of the skin, basal cell carcinoma of the skin, cervical intraepithelial neoplasia (CIN), and patients with a history of malignant tumor in the past that have been disease-free for at least 5 years
- •Active central nervous system (CNS) involvement with lymphoma
- •Pregnant or nursing women
