Lenalidomide in Treating Patients With Relapsed Mycosis Fungoides/Sezary Syndrome

Lymphoma Clinical Trial

Official title: Phase II Trial of CC-5013 (Lenalidomide, Revlimid®) in Patients With Cutaneous T-Cell Lymphoma

Status Completed

Clinical Trial Summary

RATIONALE: Lenalidomide may stop the growth of mycosis fungoides/Sezary syndrome by blocking blood flow to the cancer. PURPOSE: This phase II trial is studying how well lenalidomide works in treating patients with relapsed mycosis fungoides/Sezary syndrome.

Clinical Trial Description

OBJECTIVES: Primary - Determine the response rate and duration of response in patients with relapsed mycosis fungoides/Sézary syndrome treated with lenalidomide. - Determine the progression-free survival of patients treated with this drug. Secondary - Determine the toxicity of this drug in these patients. - Correlate the antiangiogenetic and costimulatory effects of this drug with clinical activity in skin biopsies from these patients. - Assess the specific immune effector cell recruitment and augmentation of antitumor response in these patients. (Northwestern University only) OUTLINE: This is a multicenter study. Patients receive oral lenalidomide once daily on days 1-21. Treatment repeats every 28 days for 2 courses. Patients with progressive disease are removed from study. Patients achieving complete response receive 2 additional courses of treatment beyond complete response. Patients achieving partial response or stable disease may continue to receive lenalidomide as above for up to 2 years. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients undergo tissue biopsies at baseline and on day 1 of course 2. Tissue specimens are analyzed for vessel density, presence of adhesion molecules, and immunophenotyping of dermal infiltrate.* NOTE: *At Northwestern University only, blood and tissue samples from 5-10 patients are collected. Peripheral blood samples are analyzed for immune cell repertoire (CD4+, CD8+ T cells, NK cells, NKT cells, CD4+, CD25+ T-regulatory cells, monocytes, and dendritic cell subsets), cell surface molecules, and for TH1/TH2-associated cytokines, such as interleukin (IL)-2, IL-4, IL-10, IL-12, interferon gamma, and tumor necrosis factor alpha, by flow cytometry at baseline, day 15 of course 1, and at the end of course 1. Immunological activation is assessed by analyzing surface expression of CD45RO and CTLA-4 on CD4+ and CD8+ T cells in blood and skin samples. Skin specimens are stored for future research studies on predictive markers of lenalidomide activity. After completion of study treatment, patients are followed every 3 months for 1 year. PROJECTED ACCRUAL: A total of 35 patients will be accrued for this study. ;
