NatrOVA Photoallergy Study - NatrOVA Creme Rinse in Healthy Volunteers - Full Text View

Sponsored by:	ParaPro Pharmacuticals
Information provided by:	ParaPro Pharmacuticals
ClinicalTrials.gov Identifier:	NCT00605956

Purpose

Photoallergic reactions are assumed to be due to a delayed cell-mediated hypersensitivity response that requires the presence of ultraviolet irradiation.

The predictive procedure is, therefore, based on modification of the Repeated Insult Patch Test (Kaidbey, 1991). Duplicate sets of patches of test articles are used with exposure of only one set to UV radiation and subsequent evaluation of both sets for skin reactions in order to compare irradiated versus non-irradiated test sites.
