Primary outcomePrimary: Evaluation of Systemic Absorption Through Measurement of Serum Sirolimus Trough Levels — 15; 15; 15; 14 participants
Summary
A study to evaluate safety and efficacy of topical sirolimus to treat plantar keratoderma in adults with PC. Subjects may receive either placebo or treatment with at least 1 foot receiving topical sirolimus at some time. For certain phases of the study treatment assignment to the right and left foot will be randomized in a double blind fashion. Blood levels will test systemic absorption of sirolimus. Other safety and efficacy measures will be taken through the 39-week study duration. Funding Source - FDA OOPD
