Status: Completed

The objective of this study is to assess the safety and biologic activity of intralesional injection of fluphenazine in adult subjects with psoriasis.

Clinical Details

Official title: Ascending-Dose, Double-Blind, Placebo-Controlled, Study of Intralesional Fluphenazine Hydrochloride for Psoriasis

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: The following primary biologic activity outcome measure will be evaluated at 4 weeks: Improvement in target lesion scoring.

Secondary outcome:

The following secondary biologic activity outcome measure will be evaluated at 4 weeks: Improvement from baseline in the target lesion Visual Analog Scale (VAS) score for pruritus.

Safety Outcome Measures: All adverse events will be recorded and monitored.

Fluphenazine serum levels to be measured at baseline, after 2 hours & after 1 week.

Detailed description: This is a double-blind, placebo-controlled, bilateral, ascending dose study. In vitro, fluphenazine has been shown to suppress growth of proliferating T-lymphocytes. Fluphenazine would be expected to also suppress growth of proliferating T-lymphocytes in psoriatic plaques.
