NatrOVA Photoallergy Study - NatrOVA Creme Rinse in Healthy Volunteers

Completed · Phase 1

Conditions studied: Head Lice

In brief

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.
