Official title
A Phase IV Study Of The Impact Of Vorinostat On Cellular Signaling And Cytokine Production In Cutaneous T-Cell Lymphoma Patients With Pruritus
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Mycosis Fungoides (MF) is a rare malignancy in the United States. It is the most common form of cutaneous T-cell lymphoma (CTCL). Sézary syndrome (SS) is the most severe and leukemic form of CTCL. Pruritus, or itch, is defined as an unpleasant sensation that elicits the desire to scratch. Severe itch is a manifestation of all forms of MF, especially those with patch/plaque and folliculotropic variants, as well as in Sezary patients. While severe itch causes great suffering for patients, the pathogenesis of itch in MF and Sezary syndrome is complex and not well understood. It is thought that various chemical mediators are produced by the malignant cells to cause itch. Vorinostat, an FDA approved therapy for the treatment of MF, has also been reported to relieve pruritis. The goal of the study is to evaluate how vorinostat affects different chemicals in the skin that have been known to cause itch. This is a single center, non-randomized study designed to obtain and test blood and skin tissue samples take at various time-points over 6 months in patients who are prescribed vorinostat per standard of care treatment. Samples from pruritic and non-pruritic skin and blood of MF and Sezary patients will be evaluated for the presence of chemicals thought to be important in the cause of itch in these diseases. This evaluation will include immunohistochemistry, RT-PCR, and ELISA assays. The results from this study may help define how vorinostat decreases itch in patients with MF and Sezary Syndrome.
