Pfizer was developing NPBN (PF 217830), an orally administered dopamine D2 and serotonin 5-HT1A partial agonist and 5-HT2A antagonist, for the treatment of schizophrenia. PF-217830 was discontinued from development due to either non-optimal pharmacokinetic properties or insufficient therapeutical efficacy.
