A Multicenter Study of 074-6751 Lotion in Subjects With Moderate Plaque Psoriasis

A Multicenter Study of 074-6751 Lotion in Subjects With Moderate Plaque Psoriasis

The primary objective of this study is to determine the efficacy and safety of 074-6751 Lotion applied twice daily for four weeks (28 days) in clinical subjects with moderate plaque psoriasis.

Skin diseases that cause swelling like psoriasis can be improved by using products applied to cover the skin, keeping the skin moist. Keeping the skin moist will ease the local signs and symptoms, such as skin redness, scaling, and itching in patients with plaque psoriasis. Researchers are testing 074-6751 Lotion in clinical subjects with moderate plaque psoriasis to see if it can act as a protective barrier for the skin so the skin remains moist and heals over time.

074-6751 Lotion is an investigational device. Eligible clinical subjects will be enrolled in the study and apply 074-6751 Lotion twice daily to all psoriasis plaques in the assigned Treatment Area for 28 days. Efficacy will be assessed in the Treatment Area by Investigator's Global Association (IGA) score, clinical signs of psoriasis, pruritus, and percent BSA affected. Safety will be assessed by adverse events (AEs).
