Recombinant Flt3 Ligand, Poly-ICLC, and Radiation Therapy in Treating Patients with Untreated, Relapsed, or Refractory Low Grade B-Cell Lymphoma
Your Search Criteria
This phase I / II trial studies how well recombinant Flt3 ligand, poly-ICLC, and radiation therapy work in treating patients low grade B-cell lymphoma that has not been treated, has come back (relapsed), or does not respond to treatment (refractory). Recombinant Flt3 ligand vaccine may help the body make more immune cells called dendritic cells. The poly-ICLC vaccine stimulates the immune system by activating the dendritic cells. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving recombinant Flt3 ligand, poly-ICLC, and radiation therapy may work better at treating low grade B-cell lymphoma.
- Biopsy-confirmed low-grade B-cell lymphoma; specifically, follicular grade 1, 2, or 3A, marginal zone or small lymphocytic lymphoma, of any initial stage; patients in cohort A must be relapsed/refractory after at least one prior systemic therapy and patients in cohort B must have had no prior systemic therapy
- Patients must have at least one site of disease that is accessible for intratumoral injection percutaneously (e.g. inguinal, axillary, cervical, or subcutaneous)
- Tumor specimens must be available for immunological studies, either from a previous biopsy or a new biopsy obtained before the initiation day 1 of the study
- Patients must have measurable disease other than the injection site or biopsy site, i.e. greater than 1.5 cm bi-dimensionally on standard computed tomography imaging

- Pregnant or lactating
- Any other medical history, including laboratory abnormalities, deemed by the investigator to be likely to interfere with their participation in the study, or to interfere with the interpretation of the results

Trial Objectives and Outline
I. To determine local and systemic anti-tumor effects of intratumoral injection of recombinant Flt3 ligand (rhuFlt3L/CDX-301) and poly-ICLC combined with local radiation in patients with low-grade B-cell lymphoma.
I. To determine the feasibility and safety of this treatment regimen.
I. To evaluate humoral and cellular immune responses to the combined treatment regimen.
Patients receive recombinant Flt3 ligand intratumorally on days 1-5 and 8-11, and undergo radiation therapy on days 1 and 2. Beginning day 12, patients receive poly-ICLC intratumorally for up to 8 injections on weeks 2-8 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 4 weeks, every 3-6 months for 12 months, and then every 6-12 months thereafter.
