Comment: Rodatristat (KAR5417) inhibits both isoforms of L-Tryptophan hydroxylase (TPH) [2]. The TPH enzymes are responsible for biosynthesis of 5-HT. TPH1 is expressed by intestinal enterochromaffin cells where most peripheral 5-HT is formed, and THP2 is exclusively expressed in the CNS and generates 5-HT in the brain. Rodatristat acts as a serotonin synthesis inhibitor. As rodatristat cannot cross the blood-brain-barrier its activity is restricted to inhibition of peripherally expressed TPH1 and it should not produce the undesirable psychiatric side-effects that are known to result from any reduction in central 5-HT level.
Inhibition of serotonin synthesis is being actively pursued as a mechanistic approach for application to the treatment of the expansive range of diseases that have been associated with a dysfunctional peripheral serotonin system (carcinoid syndrome, gastro-intestinal diseases, fibrotic diseases, NAFLD, atherothrombotic diseases, pulmonary arterial hypertension and some cancers and immune diseases [1,3]).

Summary of Clinical Use Click here for help
As rodatristat is administered as its prodrug rodatristat ethyl, clinical trials use the research codes of the prodrug (either KAR5585 or RVT-1201). We have curated clinical trial information against both rodatristat and rodatristat ethyl for user benefit. Clinical evauation of rodatristat in patients with pulmonary arterial hypertension (PAH) has advanced to Phase 2.
