Study of Pomalidomide in Anal Cancer Precursors

Pomalidomide is an oral immunomodulatory derivative of thalidomide. Thalidomide and its derivatives are small molecules with broad effects on immune activation, including T-cell activation and responsiveness. Pomalidomide augments T cell responsiveness and proliferation by several mechanisms, many mediated by transcriptional regulation downstream of its primary target, cereblon. Effects include increased production of IL-2 and interferon-γ (IFN-γ), enhanced CD4+ and CD8+ T cell co-stimulation.
