Abstract

Substance P-saporin (SP-SAP) has covalent bonds between the biological toxin, saporin (SAP), and the endogenous peptide, substance P (SP). SAP targets the toxin to the subset of neurons expressing the NK1 receptor. SP-SAP is currently in a phase I clinical trial and is unique as it is the only targeted toxin for pain to undergo human testing. This chapter reviews the history of SP-SAP and related NK1-receptor targeted toxins, animal data on the safety and efficacy of SP-SAP for the treatment of pain (in light of the results of NK1 receptor antagonists and knockouts/knockdowns of either SP or the NK1 receptor), and mechanisms of action of SP-SAP.
