A retrospective study of proteinuria in dogs receiving toceranib phosphate.

The incidence of proteinuria in humans receiving tyrosine kinase inhibitors has been well-documented. Reports of proteinuria with this class of drugs are limited in veterinary medicine. This retrospective study describes the incidence, severity, and progression of proteinuria in 55 dogs treated with toceranib phosphate, with or without concurrent glucocorticoid or NSAID (non-steroidal anti-inflammatory drug).
