RATIONALE: Biological therapies, such as CpG 7909, use different ways to stimulate the immune system and stop cancer cells from growing. PURPOSE: This randomized phase I/II trial is studying the side effects of CpG 7909 and to see how well it works in treating patients with cutaneous T-cell lymphoma.

Study summary:

OBJECTIVES: Primary - Determine the safety of CpG 7909, in terms of adverse events, vital signs, and laboratory and clinical findings, in patients with stage IB-IVA cutaneous T-cell lymphoma. - Determine tumor response, as measured by the Composite Assessment of Index Lesion Disease Severity (CA), in patients treated with this drug. - Determine the tolerability of this drug in these patients. - Determine the immunopharmacodynamics of this drug in these patients. Secondary - Determine disease response, based on the Physician Global Assessment of Clinical Condition (PGA), in patients treated with this drug. - Determine duration of response, based on the CA and PGA, in patients treated with this drug. - Determine time to response in patients treated with this drug. - Determine time to progression in patients treated with this drug. OUTLINE: This is a phase I, open-label, multicenter, dose-escalation study followed by a randomized phase II study. - Phase I: Patients receive CpG 7909 subcutaneously (SC) once weekly on weeks 1-24 in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of CpG 7909 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. - Phase II: Patients are randomized to receive 1 of 2 doses of CpG 7909, administered as in phase I. Patients are followed every 4 weeks. PROJECTED ACCRUAL: A total of 3-56 patients (3-36 for phase I and 20 [10 per treatment arm] for phase II) will be accrued for this study.
