• Status: Terminated
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

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.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

• Treatments: Alemtuzumab; Rituximab

Criteria

Inclusion Criteria:

• 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

• Measurable disease (lesions that can be accurately measured in 2 dimensions by CT scan with a greatest transverse diameter of >/= to 2cm or palpable lesions with both diameters of 2cm or more)

• 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.

Exclusion Criteria:

• Prior combination therapy with rituximab and CAMPATH; prior therapy with either agent alone is permitted

• A history of a T-cell lymphoma

• Known AIDS-related HIV-positive lymphoma

• For the Phase II portion of the study (once MTD has been determined), bulky disease, ie, any single mass >10cm or circulating malignant cells of 25,000/uL or more

• Prior autologous bone marrow or stem cell transplant within 6 months of study entry

• Prior allogeneic bone marrow transplant or organ transplant

• Prior radiotherapy to the only site of measurable disease

• Medical condition requiring chronic use of oral, high-dose corticosteroids

• 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

• Any significant concurrent disease or illness that would, in the opinion of the investigator, compromise patient safety or compliance, or interfere with the interpretation of study results

• Active hepatitis or a history of prior viral hepatitis B or C, or positive hepatitis B serologies without prior immunization
