Danavorexton (developmental code name TAK-925) is a selective orexin 2 receptor agonist. It is a small-molecule compound and is administered intravenously. The compound was found to dose-dependently produce wakefulness to a similar degree as modafinil in a phase 1 clinical trial. As of March 2021, danavorexton is under development for the treatment of narcolepsy, idiopathic hypersomnia, and sleep apnea. It is related to another orexin receptor agonist, firazorexton (TAK-994), the development of which was discontinued for safety reasons in October 2021.
