Phototoxicity is defined as a toxic response is elicited by topically or systemically administered photoreactive chemicals after the exposure of the body to environmental light. Several classes of photoreactive chemicals could cause phototoxic reactions when activated by light at otherwise non-toxic doses. Phototoxicity can be categorized as photoirritation, photoallergy, and photogenotoxicity. The purpose of this test is to measure the phototoxicity of a chemical. The main event in any phototoxic reaction is the absorption of photons of a wavelength that induces the excitation of the chromophore. Excitation energy is often transferred to oxygen molecules, followed by the generation of ROS (reactive Oxygen Species). Measurements are performed using a spectrometer. The determination of the ROS generation from irradiated chemicals with simulated sunlight is indicative of phototoxic potential.

Skin phototoxicity (photoirritation) is defined as an acute toxic response elicited by topically or systemically administered photoreactive chemicals after the exposure of the skin to environmental light. The in vitro reconstructed human epidermis phototoxicity test (RhE PT) is used to identify the phototoxic potential of a test chemical after topical application in reconstructed human epidermis (RhE) tissues in the presence and absence of simulated sunlight.

This book provides latest findings in organotypic models in drug development and provides the scientific resonance needed in an emerging field of research in disciplines, such as molecular medicine, physiology, and pathophysiology. Today the research on human-based test systems has gained major interest and funding in the EU and the US has increased over the last years. Moreover, so-called 3R (reduce, replace, refine animal experiments) centres have been established worldwide.

The present Key Event based Test Guideline addresses the human health hazard endpoint skin sensitisation, following exposure to a test chemical. Skin sensitisation refers to an allergic response following skin contact with the tested chemical, as defined by the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS). This Test Guideline is proposed to address the Molecular Initiating Event leading to skin sensitisation, namely protein reactivity, by quantifying the reactivity of test chemicals towards model synthetic peptides or amino acid derivatives containing either lysine or cysteine. This Test Guideline provides three in chemico test methods addressing the same Key Event on the Adverse Outcome Pathway for Skin Sensitisation: (i) the Direct Peptide Reactivity Assay – DPRA, (ii) the Amino Acid Derivative Reactivity Assay – ADRA and (iii) the kinetic Direct Peptide Reactivity Assay – kDPRA. The DPRA and ADRA are used for supporting the discrimination between skin sensitisers and non-sensitisers in accordance with the UN GHS. In contrast, the kDPRA allows discrimination of UN GHS subcategory 1A skin sensitisers from those not categorised as subcategory 1A, i.e. subcategory 1B or no category but does not allow to distinguish sensitisers from non-sensitisers.
