A prospective treatment for patients with schizophrenia, who have not responded to other drugs, failed to show statistical superiority in a Phase 3 trial compared with conventional therapy, H. Lundbeck A/S announced on 25 October.
The treatment, Lu AF35700, is a dopamine D1 and D2 antagonist with a high occupancy of the 5-HT2A and 5-HT6 serotonin receptors. The relatively low D2 receptor occupancy compared with the D1 receptor was expected to result in a better side effect profile.
