Vofopitant (previously known as GR205171), a tetrazole-derivative, was developed as a neurokinin1 receptor antagonist. Vofopitant was studied in clinical trials phase II for the treatment of primary insomnia and posttraumatic stress disorder. However, these studies were discontinued due to lack of effectiveness. In addition, vofopitant participated in phase I for patients with bipolar disorder. However, this study was terminated because of the slow recruitment; trial unlikely to reach completion.
