Phase I trials have been completed in healthy Japanese and Caucasian volunteers.[1][2]

Potential common adverse effects include thermohypoesthesia, chills, feeling cold, and feeling hot.[2]


When administered orally once a day, mavatrep reached steady-state in healthy volunteers in approximately 14 days.[2] It has a relatively long half life between 68–101 hours in Japanese subjects and between 82–130 hours in Caucasian subjects.[2]

Mavatrep is largely eliminated nonrenally. Mavatrep appears to be metabolized into two primary metabolites which are also eliminated nonrenally.[2]
