Study Description

Brief Summary

The idiotype of the immunoglobulin on a given B cell malignancy (Id) can serve as a clonal marker, and a previous pilot study in lymphoma patients has demonstrated that autologous Id protein can be formulated into an immunogenic, tumor specific antigen by conjugation to a carrier protein (KLH) and administration with an emulsion-based adjuvant. The goals of vaccine development in the current study are to develop vaccines: 1) with improved potency and 2) which are more effective at inducing cell-mediated immune responses. The selection of GM-CSF as the immunological "adjuvant" is a direct extension of our laboratory studies in small animal models demonstrating that GM-CSF can enhance the potency of the prototype Id-KLH vaccine by augmenting almost exclusively the cellular arm of the immune response.

The objectives of this study are: 1) to evaluate cellular and humoral immune responses against the unique idiotype of the patient's lymphoma and 2) to evaluate the ability of the Id vaccine to clear the bone marrow of malignant cells detectable by pathologic examination or molecular examination (polymerase chain reaction amplification of the rearranged bcl-2 oncogene).

The goal of this study is to treat previously untreated patients with follicular lymphomas to complete remission or minimal residual disease with ProMACE chemotherapy. Three to six months after completion of chemotherapy, in an effort to reduce the relapse rate (by eradicating microscopic disease resistant to chemotherapy), patients will receive an autologous Id vaccine administered in combination with GM-CSF. Id-KLH (0.5 mg) is administered subcutaneously. GM-CSF is administered subcutaneously locally with the vaccine on the day of vaccination and for the three consecutive days following vaccination as close to the initial vaccination site as possible at one of two doses (patients are randomized to either a high or low dose, 500 or 100 micrograms/m2).

We plan to accrue 42 patients. Twenty-nine patients have been enrolled. Sixteen patients have entered and/or completed the vaccination phase. Patients have demonstrated significant lymphoproliferative responses specific for autologous idiotype of a magnitude which is significantly greater than previously observed.

Stage III or IV lymphoma.

Only previously untreated patients are eligible.

Previous treatment with radiation alone (less than TBI) is permissible.

A single peripheral lymph node of at least 2 cm size accessible for biopsy/harvest.

Karnofsky status greater than or equal to 70 percent.

Life expectancy of greater than 1 year.
