Clinical Trial Summary

This study examines the effect of Goeckerman therapy (a combination of phototherapy and topical crude coal tar), crude coal tar alone, and phototherapy alone on the immunologic and genetic environment within psoriatic skin lesions.

Description:

This is a three-arm, open-label study to examine the effect of Goeckerman therapy. Goeckerman therapy is known for its high efficacy and favorable safety profile in the treatment of psoriasis. It consists of a combination of phototherapy and topical crude coal tar). This study will examine how Goeckerman therapy, crude coal tar alone, and phototherapy alone affect the mmunologic and genetic environment within psoriatic skin lesions. Fifteen subjects with moderate to severe psoriasis will be enrolled. Biopsy samples will be collected and undergo molecular profiling to further elucidate the mechanism of action by which Goeckerman treatment improves psoriatic skin lesions.

Intervention

Other:
• Goeckerman Therapy
The Goeckerman regimen consists of exposure to narrowband ultraviolet B (NB-UVB) light phototherapy and application of crude coal tar to the skin 5 days per week. The treatment will occur the UCSF outpatient skin treatment center for approximately 4-5 hours, 5 days a week for 6 weeks (total of 30 sessions). The treatment is consistent with the standard of care Goeckerman treatment protocol at UCSF.

Drug:
• Crude Coal Tar Only
A topical medication consisting of crude coal tar will be applied to the psoriatic skin under plastic wrap occlusion for approximately up to 4-5 hours, 5 days a week for 6 weeks (total of 30 sessions), at the outpatient skin treatment center at UCSF.

Device:
• Phototherapy Only
Light treatment with narrowband ultraviolet B (NB-UVB) phototherapy three days per week for 12 weeks at the UCSF Phototherapy Center per the standard UCSF phototherapy protocol, in which starting dose is based on the subject's Fitzpatrick skin type and gradually increased as tolerated. Each phototherapy treatment will last approximately from under 1 minute to less than 15 minutes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of differentially expressed immune cell populations	Perform quantitative analysis of the immunologic and genetic changes in immune cell populations after treatment with traditional Goeckerman (NBUVB + coal tar), coal tar only, and NB-UVB only, at weeks 2, 4, and 12 compared to baseline week 0. The immunologic profiles will be compared between subjects receiving the traditional Goeckerman therapy (NB-UVB + coal tar), coal tar only, and NB-UVB therapy only.	12 weeks
Secondary	Number of differentially expressed genes and pathways	Quantify the number of differentially expressed genes in each cell population by RNA-sequencing at weeks 0, 2, 4, 12 after receiving traditional Goeckerman therapy (NB-UVB + coal tar), coal tar only, and NB-UVB therapy only.	12 weeks
