Brief 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

Experimental: Split-body 1% sirolimus cream (TD201 1%)
This is a split-body design. Subjects will self-administer 1% topical sirolimus cream or placebo cream (no drug, vehicle control) on the plantar surface of each foot. At least one foot will be treated with topical sirolimus at some time during the study. Application will be one time daily for a total of 26 weeks. There will be an additional follow-up visit 3 months after the last application of study drug. The total duration of the study is 39 weeks.

Primary Outcome Measures :
- Evaluation of Systemic Absorption Through Measurement of Serum Sirolimus Trough Levels [ Time Frame: Two weeks and every 1-2 months for 24 weeks or within 2 weeks after the last dose of study drug ]The primary outcome measure for this Phase 1b safety study is evaluation of system absorption through measurement of serum sirolimus trough levels. The limit of detection of the assay was 2.0 ng/mL.
Secondary Outcome Measures :
- Weekly Assessments Recorded in the PC Quality of Life Index [ Time Frame: Weekly for 39 weeks ]Patient-reported weekly assessment in the PC Quality of Life Index
- Daily Assessments Recording in the PC Measurement Diary [ Time Frame: Weekly for 39 weeks ]
Other Outcome Measures:
- Investigator Assessment of Local Tolerability [ Time Frame: Prior to application of study drug and within 15-45 minutes after application of study drug at each visit for 39 weeks ]Investigator assessment of local tolerability at the application sites on the plantar surfaces will be evaluated by the Investigator according to a 4-point scale (0, 1, 2, or 3; none to severe) with regard to: erythema, pruritis, stinging/burning, and crusting/erosion
- Standardized Photographs [ Time Frame: Each study visit over 39 weeks ]An expert in the disease who is blinded to the study treatment will read the photographs of the callus area taken at each study visit. The reader will assess changes to the calluses based on criteria such as blisters, cracks, small/large size, and red or bloody spots on the callus. Change in calluses will be reported for both the right and left foot.
