Group description: Prospective, phase II non-randomized, open label study of single agent everolimus for the treatment of CTCL recurrent or refractory to at least one previous treatment other than topical medication. The purpose will be evaluation of safety and anti-tumor response as evaluated by serial skin examinations and assessment of tumor burden in tissue and blood.

This study will be conducted in 2 stages. During stage 1 we will enroll a maximum of 11 subjects to evaluate response rate and will only continue to stage 2, if we observe two or more responses. During stage 2, we will expand the study to an overall N of 28 patients.

Everolimus will be administered orally as once daily dose of 10 mg continuously from study day 1 until progression of disease or unacceptable toxicity.
