Trial Information

Phase II Study of FavId (Tumor-Specific Idiotype-KLH) and Soluble GM-CSF Immunotherapy in Patients With Stable or Progressive Grade 1 and 2 Follicular B-Cell Lymphomas

The purpose of this study was to assess the ability of active immunotherapy to induce tumor
regressions in relapsed low-grade lymphoma. B-cell malignancies express a unique antigen,
the immunoglobulin idiotype (Id), on their surface. Each B-cell harbors a unique genetic
sequence used in the production of immunoglobulin idiotype. B-cell lymphomas arise from the
clonal expansion of a single B-cell and all tumor cells express that unique Id protein. No
normal B-cells possess that Id on their cell surface. Hence, Id protein should serve as an
ideal target for individualized active immune therapy of NHL. Many of the antigens expressed
by tumors (including Id) are only weak immunogens. To augment the immune response against
Id, the Id protein must be chemically coupled to a strongly immunogenic protein. Keyhole
limpet hemocyanin (KLH) is a commonly used protein carrier capable of augmenting the body's
immune reaction against Id protein. While initial studies reported a predominately humoral
(antibody) response, cellular immunity (T-cells) also plays a critical role in anti-tumor
immunity. GM-CSF is a hematopoietic growth factor that stimulates T-cell proliferation.

Inclusion Criteria

Inclusion Criteria

- Histologically confirmed grade 1 or 2 follicular B-cell lymphoma (WHO classification)

- Patients that have responded with at least stable disease to their most recent chemo-
or anti-CD20 antibody (Rituxan®, Zevalin, Bexxar) therapy for a minimum of 90 days
and who currently have relapsed or who continue to have stable disease.

- Tumor accessible for biopsy or previously existing biopsy material

- At least 1 additional bidimensional lesion measuring at least 2 cm in each dimension

- Performance status (ECOG) of 0, 1 or 2

- Absolute Granulocyte count ? 1,000/mm3

Exclusion Criteria

- Patients who have had more than 3 prior chemotherapy or anti-CD20 regimens

- Prior fludarabine

- Prior tumor-specific idiotype immunotherapy

- Patients whose disease has progressed within the first 90 days of their last
chemotherapy or anti-CD20 treatment

- Prior splenectomy

- Surgery, cancer radiotherapy, steroid therapy, immunotherapy or chemotherapy within
90 days prior to first scheduled vaccination

- Serious non-malignant disease (e.g., psychiatric disorders, congestive heart failure,
or active uncontrolled bacterial, viral, or fungal infections), or other conditions
which, in the opinion of the investigator would compromise protocol objectives

carcinomas) unless in remission for > 2 years
