Conditions

Outcome Measures

Primary Outcomes (1)

  • Observed Photoallergy (Photosensitization): Number of Skin Sites by Maximum Total Irritation Score

    The determination of photosensitization reactions was summarized by frequency counts of the total dermal irritation score during the Challenge Phase. Total Irritation Score is a visual score summing the degree of erythema and edema. Minimum score=0, maximum score=5; higher score=worse outcome

    Skin sites evaluated 24, 48, and 72 hours after patch removal and irradiation challenge

Study Arms (1)

Single Cohort (Healthy Volunteers)

OTHER

Diacerein 1% topical ointment Intra-subject photoallergy (photosensitization) test

Drug: Diacerein 1% ointment

Interventions

During the 3-week Induction Phase, diacerein 1% ointment and vehicle ointment were applied under fully occlusive patch conditions to two randomly assigned skin sites on the infrascapular region of the back twice each week for approximately 24 hours (±4 hours). After patch removal, one application site and an untreated control site was irradiated, and all sites were evaluated 24 hours, 48 hours, and 72 hours later. Following a rest period, during the Challenge Phase, the study products were applied to two naive sites once for approximately 24 hours (±4 hours). After patch removal, one application site and an untreated control site was irradiated, and all sites were evaluated 24 hours, 48 hours, and 72 hours later. A Re-Challenge was to be performed if a response observed during the Challenge Phase indicated photosensitization.
