Dermal Atrophy
Conditions
Brief summary
This trial examines the impact of a topical formulation of rapamycin on dermal thickness and senescence.
Detailed description
Aging of the skin is the most prominent feature of the aging process, being caused by multiple factors such as intrinsic aging process and UV light exposure. Dermal atrophy, also called skin atrophy or atrophy, is a disorder manifesting thinning or depression of skin due to reduction of underlying tissue. Dermal atrophy is a major clinical problem in the elderly population. Loss of dermal integrity leads to increased fragility of the skin and precludes the use of intravenous lines in many cases. Skin tears are a significant concern in elderly individuals directly related to dermal atrophy. Impairment in wound healing is an important clinical sequelae of reduced dermal integrity leading to an increase in the number of the infections and complications following injury. Seborrheic keratosis, which comprise focal areas of epidermal thickening, can occur, possibly representing a response to damage. It has been estimated that 100% of individuals over 50 years of age harbor at least one of these lesion. There is not treatment for dermal atrophy and seborrheic keritoses require excision if they become large enough to cause discomfort or distress. Therefore, there is a need to develop novel compositions and methods for treating or preventing certain age-related dermal conditions. Rapamycin is an FDA approved drug that has been in clinical use for over 15 years. Systemic application of rapamycin has been a central part of immuno suppressive therapy for transplant patients in combination with other immuno suppressants. The safety record for systemic use of rapamycin is excellent and few side effects are associated with extended use.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dermal thickness | 6-8 months | dermal thickness as assessed by direct measurement |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Gene expression | 6-8 months | immunohistochemistry and gene expression analysis |
| Seborrheic Keratosis | 6-8 months | clinical severity will be assess using a 1-5 rating scale of severity. Lesions will be evaluated for their progression over the treatment period relative to the known course of growth for Seborrheic Keratoses. |
