Trial Information

A Phase III Clinical Trial of Immunotherapy With Humanized LL2 IgG (Epratuzumab) in Patients With Low-Grade Follicular, B-Cell Non-Hodgkin's Lymphoma Refractory to Rituxan (Rituximab)


OBJECTIVES:

- Determine the safety of epratuzumab in patients with rituximab-refractory low-grade
follicular B-cell non-Hodgkin's lymphoma.

- Confirm the convenient administration of this drug in this patient population.

- Determine the efficacy of this drug in terms of objective response rate in these
patients.

- Determine the duration of response and time to progression in patients treated with
this drug.

OUTLINE: This is a multicenter study.

Patients receive epratuzumab IV over 15-60 minutes on days 1, 8, 15, and 22.

Patients are followed every 8 weeks for 10 months and then every 3 months for up to 4 years.

PROJECTED ACCRUAL: Approximately 30-100 patients will be accrued for this study.

Inclusion Criteria


DISEASE CHARACTERISTICS:

- Histologically confirmed low-grade follicular B-cell non-Hodgkin's lymphoma

- Small cleaved cell OR

- Mixed cell

- The following are ineligible:

- Primary CNS lymphoma

- HIV lymphoma

- Richter's lymphoma

- Bulky disease (any single mass greater than 10 cm)

- Pleural effusion with positive cytology for lymphoma

- Failed prior standard chemotherapy for non-Hodgkin's lymphoma

- Refractory to at least 1 prior treatment with rituximab

- Disease progression or failure to achieve objective response within 6 months of
beginning rituximab therapy

- At least 1 bidimensionally measurable lesion

- At least 1.5 cm by CT scan NOTE: A new classification scheme for adult
non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or
"aggressive" lymphoma will replace the terminology of "low", "intermediate", or
"high" grade lymphoma. However, this protocol uses the former terminology.
