Vorinostat (SAHA) and Lenalidomide After Autologous Transplant for Patients With Multiple Myeloma
Vorinostat (SAHA) and Lenalidomide After Autologous Transplant for Patients With Multiple Myeloma
RATIONALE: Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lenalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Giving vorinostat together with lenalidomide may kill more cancer cells.
PURPOSE: This phase I trial is studying the side effects and best dose of vorinostat when given together with lenalidomide after autologous stem cell transplant in treating patients with multiple myeloma.
OBJECTIVES:
Primary
Secondary
OUTLINE: This is a dose-escalation study of vorinostat.
Patients receive oral vorinostat alone once daily on days 1-21 in course 1. For the second and subsequent courses, patients receive oral vorinostat in combination with oral lenalidomide once daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Patients undergo blood sample collection periodically for correlative laboratory studies. Studies include functional immune assays (T-cell and natural killer cell activity and regulatory T-cell recovery) by fluorescence activated cell sorting (FACS) or ELISPOT; analysis of inflammatory markers (cytokines and catecholamines); and analysis of global H3 and H4 acetylation by immunohistochemistry.
Quality of life is assessed periodically using the Brief Pain Inventory (Short Form), The Center for Epidemiologic Studies Depression Scale (CES-D-10), a 9-item Brief Fatigue Inventory, and the FACT-G questionnaires.
After completion of study treatment, patients are followed for at least 30 days.
