Delayed-type hypersensitivity (DTH) is a common reaction caused by various drugs, especially antineoplastic drugs, which may affect patients' quality of life. However, there is currently a lack of standardized methods for evaluating the sensitizing potential of drugs in the preclinical phase. This study aimed to adapt in vitro techniques to predict the sensitizing potential of antineoplastic agents and discovered that inhibition of the VEGFR1 pathway may be a potential trigger of DTH.
Delayed-type hypersensitivity (DTH) is caused by a broad number of drugs used in clinic, and antineoplastic drugs show an elevated proportion of DTH, which potentially affects the quality of life of patients. Despite the serious problem and the negative economic impact deriving from market withdrawal of such drugs and high hospitalization costs, nowadays, there are no standard validated methods in vitro or in vivo to evaluate the sensitizing potential of drugs in the preclinical phase. Enhanced predictions in preclinical safety evaluations are really important, and for that reason, the aim of our work is to adapt in vitro DPRA, ARE-Nrf2 luciferase KeratinoSens (TM), and hCLAT assays for the study of the sensitizing potential of antineoplastic agents grouped by mechanism of action. Our results reveal that the above tests are in vitro techniques able to predict the sensitizing potential of the tested antineoplastics. Moreover, this is the first time that the inhibition of the VEGFR1 pathway has been identified as a potential trigger of DTH.
