Abstract

Complement activation-related pseudoallergy (CARPA) is an acute adverse immune reaction caused by many nanomedicines. There is a regulatory need for a sensitive and standardizable in vivo predictive assay. While domestic pigs are a sensitive animal model, miniature pigs are favored in toxicological studies yet their utility as a CARPA model has not yet been explored. Herein, we used liposomal doxorubicin and amphotericin B (Doxil/Caelyx and AmBisome), Cremophor EL and zymosan as CARPA triggers to induce reactions in miniature and domestic pigs, and compared the hemodynamic, hematological, biochemical, and skin alterations. The changes observed after administration of the test agents were very similar in both pig strains, suggesting that miniature pigs are a sensitive, reproducible, and, hence, validatable animal model for CARPA regulatory testing.
