Brief Summary

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

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.

Conditions

Psoriasis

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: TRIPLE

Study Groups

Placebo

The sterile placebo: Bacteriostatic Sodium Chloride for Injection.

Group Type: PLACEBO_COMPARATOR

Placebo

Intervention Type: DRUG

Intralesional injection of placebo

Fluphenazine

This will be an ascending dose study with the first cohort of 5 subjects dosed at 100 µg/mL, followed by cohorts at 500 and 2500 µg/mL. Dosing will be on Days 0, 7 and 14 and will consist of 5, or 10, 100 µL injections into the psoriatic lesion. The number of injections will depend on the lesion size. As this is a vehicle controlled study, subjects will receive intralesional injections of both drug and placebo, each into a separate target plaque, in a randomized fashion.
