About the Phase 1/2a Study with ESR-114

The study is designed to evaluate the safety, tolerability, dose-response and pharmacokinetics of two concentrations of ESR-114 topical gel compared with its vehicle (placebo). Over 110 subjects with mild to moderate psoriasis will be randomized into this double-blind, placebo-controlled trial across 10 centers in the United States and Canada.

About ESR-114 Topical Gel

ESR-114 topical gel is a selective, potent inhibitor of RORγt designed to have its pharmacological activity targeted to the skin with minimal systemic absorption. Inhibition of RORγt has been shown to reduce production of the inflammatory cytokine IL-17, which plays a key role in psoriasis and other autoimmune disorders. ESR-114 topical gel is currently being evaluated to determine if it may reduce or treat the clinical manifestations of psoriasis.

About Psoriasis

Psoriasis is a chronic, autoimmune disease that results in raised, red, scaly patches on the skin. It is estimated that 7.5 million Americans and 125 million people worldwide have psoriasis. Between 10-30% of people with psoriasis also develop psoriatic arthritis. Patients are categorized into mild, moderate or severe with the National Psoriasis Foundation. The majority of psoriasis patients are in the mild to moderate category.
