Using Lexicon's proprietary knock-out mouse technology, company scientists established that serotonin in the brain and neurons is synthesized by TPH2, an enzyme related to but distinct from TPH1, which is responsible for the synthesis of almost all peripheral serotonin. Knock-out studies showed that mice lacking a functional TPH1 gene exhibited normal brain levels of serotonin with no detectable levels in the periphery. Importantly, the TPH1 knockout mice were healthy and exhibited no significant adverse effects.
Top-line Phase 1 clinical results for LX1031 are expected to be presented at the American College of Gastroenterology's Annual Scientific Meeting in Philadelphia in October.
