Lumateperone (INN ; brand name Caplyta kəp-LY-tə, developmental codes ITI-007 and ITI-722) is a butyrophenone atypical antipsychotic developed by Intra-Cellular Therapies, licensed from Bristol-Myers Squibb, for the treatment of schizophrenia,[3] and currently in development for bipolar depression and other neurological indications.[4]
The most common side effects include sleepiness and dry mouth.[5]
Medical uses
Schizophrenia
On December 20, 2019, the United States Food and Drug Administration (FDA) approved lumateperone for the treatment of schizophrenia in adults.[5][6][7] Lumateperone is FDA approved for this indication only at the 42 mg dose (60 mg lumateperone tosylate), despite being studied at lower doses (14 and 28 mg) and a higher dose (84 mg).[2]
Clinical Studies
Bipolar depression
Two Phase III lumateperone monotherapy studies were conducted and completed for the treatment of bipolar depression, those being trial Study 401 and Study 404.[8] A third trial, Study 402, aims to test lumateperone in addition to lithium or valproate,[9][10] the data pertaining this trial is due out in 2020.[11][10]
Study 401 was conducted solely in the United States while Study 404 was a global study and included patients from the US.[12][13] Of the entire Study 404 population (381 patients), two-thirds were from Russia and Colombia. At the completion of the two monotherapy Phase III trials only Study 404 met its primary endpoint and one of its secondary endpoints.[14][15] In Study 404, patients received 42 mg lumateperone once daily or placebo for six weeks. Study 404 patients saw an improvement of depressive symptoms compared to placebo as documented by a change in MADRS total score of 4.6.[16]

Mechanism of action
Lumateperone acts as an antagonist of 5-HT2A receptor and antagonizes several dopamine receptor subtypes (D1, D2, and D4). It has moderate serotonin transporter reuptake inhibition. It has additional off-target antagonism at alpha-1 receptors, without appreciable antimuscarinic or antihistaminergic properties.[2]
Pharmacokinetics
After taking the medication by mouth, lumateperone reaches maximum plasma concentrations within 1–2 hours and has a terminal elimination half-life of 18 hours.[2] Lumateperone is a substrate for numerous metabolic enzymes, including various glucuronosyltransferase (UGT) isoforms (UGT1A1, 1A4, and 2B15), aldo-keto reductase (AKR) isoforms (AKR1C1, 1B10, and 1C4), and cytochrome P450 (CYP) enzymes (CYP3A4, 2C8, and 1A2).[2]
Lumateperone does not cause appreciable inhibition of any common CYP450 enzymes. It is not a substrate for p-glycoprotein.[2]
Society and culture
Economics
The failure of Study 401 caused Intra-Cellular's stock price to fall.[17][10] Their stock fell again on July 23, when the US Food and Drug Administration (FDA) canceled a Psychopharmacologic Drugs Advisory Committee meeting.[18][19]
History
Lumateperone was approved for medical use in the United States in December 2019,[5][6][7] and became available in February 2020.[2]
The FDA approved lumateperone based on evidence from three clinical trials (Trial 1/NCT01499563, Trial 2/NCT02282761 and Trial 3/NCT02469155) that enrolled 818 adult participants with schizophrenia.[5] The trials were conducted at 33 sites in the United States.[5] Trials 1 and 2 provided data on the benefits and side effects of lumateperone, and Trial 3 provided data on side effects only.[5]
Three trials provided data for the approval of lumateperone.[5] In each trial, hospitalized participants with schizophrenia were randomly assigned to receive either lumateperone or a comparison treatment (placebo or active comparator) once daily for four weeks (Trials 1 and 2) or six weeks (Trial 3).[5] Neither the participants nor the health care providers knew which treatment was being given until after the trials were completed.[5]
Trials 1 and 2 provided data for the assessment of benefits and side effects through four weeks of therapy.[5] Benefit was assessed by measuring the overall improvement in the symptoms of schizophrenia.[5] Trial 3 provided data for the assessment of side effects only during six weeks of therapy.[5]
