Expanded Access Study of Iodine-131 Anti-B1 Antibody for Relapsed/Refractory Low-Grade and Transformed Low-Grade Non-Hodgkin's Lymphoma

Inclusion Criteria


- Patients must have a histologically confirmed diagnosis of low-grade NHL or
transformed low-grade NHL according to International Working Formulation for Clinical
Usage. (The following low-grade histologies are to be included: small lymphocytic;
follicular, small cleaved; and follicular, mixed small-cleaved and large cell [<50%
large cell component]). Tumor must be positive for CD20 antigen.

- Patients must have been treated with at least one chemotherapy regimen and have
relapsed or progressed, or failed to achieve an objective response (CR or PR) on
their last chemotherapy regimen.

- Patients must have a Karnofsky performance status of at least 60% and an anticipated
survival of at least 3 months.

- Patients must have an absolute granulocyte count greater than or equal to 1,500/mm3,
a platelet count greater than or equal to 100,000/mm3, and not require sustained
support of hematopoietic cytokines or transfusion of blood products.

- Patients must have adequate renal function (defined as serum creatinine <1.5 times
upper limit of normal), hepatic function (defined as total bilirubin <1.5 times upper
limit of normal), and hepatic transaminases (defined as AST <5 times upper limit of


- Patients with a mean of >25% of the intratrabecular marrow space involved with
lymphoma on bilateral iliac crest bone marrow biopsy. Patients with a <10% lymphoma
involvement on unilateral biopsy do not require bilateral biopsy.

- Patients who have received cytotoxic chemotherapy, radiation therapy, immunotherapy,
or cytokine treatment within 4 weeks prior to study entry (6 weeks for nitrosourea
compounds) or who exhibit persistent clinical evidence of toxicity. Patients who
have received systemic steroids within 1 week of study entry are excluded, except
patients on maintenance steroid therapy for a non-cancerous disease.

- Patients who have undergone treatment with either stem cell or bone marrow

- Patients with active obstructive hydronephrosis.

- Patients with evidence of active infection requiring IV antibiotics at the time of
study entry.

- Patients with New York Heart Association class III or IV heart disease or other
serious illness that would preclude evaluation.

- Patients with known HIV infection.

- Patients who are pregnant or nursing. Males and females must agree to use a
contraceptive method from enrollment to 6 months after receiving Iodine-131 Anti-B1

- Patients with prior malignancy other than lymphoma, except for adequately-treated
skin cancer (basal cell or squamous cell carcinoma), in situ cervical cancer, or
other cancer for which the patient has been disease-free for 5 years. Patients who
have been disease-free of another cancer for greater than 5 years must be carefully
assessed at the time of study entry to rule out recurrent disease.

- Patients with progressive disease within 1 year of irradiation arising in a field
that has been previously irradiated with more than 3500 cGy.

- Patients who previously received radioimmunotherapy.

- Patients who are receiving either approved or non-approved (through another protocol)
anti-cancer drugs or biologics.

- Patients with known brain or leptomeningeal metastases.

- Patients who are HAMA positive.
