The purpose of this study is to determine if combining a daily at-home regimen using an LCD Solution with a 3 times weekly outpatient narrowband UVB phototherapy regimen could be a safe, effective, rapid, and, convenient treatment for plaque psoriasis.
Use of coal tar with narrowband (NB) ultraviolet B (UVB) light (the Goeckermen regimen) is an effective treatment for plaque psoriasis that has become impractical in outpatient care mainly due to the inconvenience and aesthetic concerns of coal tar. This study aims to evaluate the safety, efficacy, and convenience of adding a novel liquor carbonis distillate (LCD) (coal tar) solution to standard NB\_UVB phototherapy in adults with chronic plaque psoriasis. Patients will apply LCD solution to half the body, twice daily at home and receive outpatient full-body NB-UVB light therapy 3 times a week for up to 12 weeks. A blinded investigator will grade psoriasis severity of body halves and bilateral target lesions and monitor adverse reactions. Patients will rate their psoriasis symptoms and LCD solution aesthetics. Incorporating an at-home regimen with a novel LCD solution into outpatient NB-UVB light therapy is safe, convenient, and effective and can improve psoriasis more quickly than NB-UVB light therapy alone.

The Difference in Bilateral Static Physician's Global Assessment (sPGA) Scores, and Erythema, Scaling, and Induration (ESI) Scores of Bilateral Target Lesion Scores Across Visits for Each Condition and Between Conditions.
Twelve (12) participants were followed over a 12-week treatment period. Treatment was administered bilaterally as they applied LCD solution to one half of their body while receiving full-body NB-UVB light therapy. The difference in their sPGA, and ESI scores of bilateral target lesions were measured across all visits. PGA scores are calculated using a 6-point scale from 0 (clear) to 5 (very severe). Erythema, induration and scaling scores use a 5-point scale from 0 (none) to 4 (very severe).
Time frame: 12 weeks of treatment
The Difference in Number and Severity of Treatment-related Adverse Reactions Between Conditions.
Number of subjects who experienced and adverse reaction due to UVB + LCD, versus number of subjects who experienced an adverse reaction due to UVB therapy alone.
Time frame: 12 weeks of treatment
