Tilapertin (INN), also known as AMG-747,^[1] is a investigational drug which was being evaluated as an antipsychotic.^[2]

Mechanism of action

Tilapertin appears to act via the blocking of the type 1 glycine transporter,^[3] making it a glycine re-uptake inhibitor.

History

Two studies have been made in order to determine the safety of tilapertin and its potential as an add-on to anti-psychotic therapy in people with schizophrenia. These studies were later halted due to a case of Stevens–Johnson syndrome in one of the participants.^[3]
