Low-dose UVA1 Radiation in Cutaneous Lupus Patients

Study Overview
=================
Brief Summary
-----------------
The investigators are conducting an open-label clinical trial determining the effects of UVA1 phototherapy on cutaneous lupus (CLE) patients. Past research on systemic lupus (SLE) subjects indicates that this treatment is likely to be effective in treating cutaneous lupus with few side effects. The fact that most CLE patients are seen at dermatology clinics also increases the usefulness of this study because there is a large probability that phototherapy treatment will be accessible for many of the patients that stand to benefit from it.

Detailed Description
-----------------
Study subjects will receive low dose (20 J/cm2) UVA1 phototherapy treatment three times per week for 10 weeks. Each treatment will take less than 30 minutes. This period will be followed by an eight-week observation phase to assess longer term effects of the treatment. Patients will be assessed for disease activity, and blood studies and photos will be completed prior to, during, and after phototherapy treatment. Optional skin biopsies of affected and unaffected skin will be performed at the beginning and end of the active treatment phase.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Cutaneous Lupus Disease Area and Severity Index (CLASI) Activity Score | The CLASI activity score represents the amount of skin disease activity in cutaneous lupus patients, as evaluated by a provider. The minimum score is 0 (no disease activity), and the maximum score is 70 (maximum/worst disease activity). The change is measured at the start and end of the UVA1 trial therapy. | 10 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Cutaneous Lupus Disease Area and Severity Index (CLASI) Damage Score | The CLASI damge score represents the amount of skin disease damage in cutaneous lupus patients, as evaluated by a provider. The minimum score is 0 (no disease damage), and the maximum score is 80 (maximum/worst disease damage). The change is measured at the start and end of the UVA1 trial therapy. | 10 weeks |
