A 4-Day Study to Evaluate the Photoxicity of Diacerein 1% Topical Ointment in Healthy Volunteers
A 4 Day, Randomized Study to Evaluate the Potential of CCP-020 (Diacerein 1%) Topical Ointment to Induce a Phototoxicity Skin Reaction in Healthy Subjects, Using a Controlled Photopatch Test
Study Overview
Detailed Description
This was a single-center, randomized, within-subject comparison of diacerein 1% ointment and vehicle ointment applied to 2 sites on opposite sides of the the infrascapular area of the back under occlusive patch conditions for approximately 24 (±2) hours. Product was applied according to the randomization scheme in an amount of 0.2 mL, once during the study.
Patches were removed and 1 of the skin sites for each product was irradiated and 1 remained non-irradiated. The irradiated and non-irradiated sites were compared with each other and with an untreated irradiated control site.

Experimental: Single Cohort (Healthy Volunteers)
Single cohort received diacerein 1% ointment
|
Diacerein 1% ointment and vehicle ointment were applied on Day 1 at two randomly assigned skin sites on each side of the lower thoracic area of the back according to a randomization scheme.
One side of the back was irradiated on Day 2, including an untreated irradiated control site, and the other side was to remain non-irradiated.

---|---|---|
Observed Phototoxicity
Time Frame: Days 3 and 4 (24 and 48 hours post site irradiation procedure)
|
The mean of the total irritation scores 24 and 48 hours post the site irradiation procedure.
( i.e.
Day 3 and 4) Total Irritation Score is a visual score summing the degree of erythema and edema.
Minimum score= 0; Maximum score = 5; higher score = worse outcome.
