Condition/Disease

Psoriasis or nail psoriasis

Objectives

P000888 ointment is developed by pharmaceutical company GALDERMA R&D based on a new extraction from commercial indigo naturalis, which is called “Qingdai” and extracted from the leaves and stems of plants such as; Baphicacanthus cusia. Indigo naturalis has been used for decades in Asia as traditional Chinese medicine to treat various inflammatory diseases including psoriasis as systemic therapy in Chinese patients. NP000888 has been developed by Galderma R&D in an ointment formulation with 270 μg/g for the treatment of plaque and nail psoriasis.. So far NP000888 has been clinically evaluated in a single Phase 1 study conducted in 54 healthy subjects aimed to assess the photo allergenic potential using patch tests methodology (up to 100 µL of the product applied) and no photoallergic reaction was observed in the conditions of this study. The patch test is used to see if a skin reaction caused by contact with a specific chemical or substance. The objective of this study is first to confirm the efficacy and safety of NP000888 in plaque and nail psoriasis. A secondary objective is also to measure in 20 patients if the alkaloids (mainly Indirubin) may be detected in blood after application on skin (optional pharmacokinetic profile) and in which quantity in patient treated with NP000888 ointment.
