Abstract
This study aimed to investigate the effects of lumateperone as a combination therapy with sertraline in major depressive disorder (MDD). The 8-week, double-blind, placebo-controlled trial was registered with the Iranian Registry of Clinical Trials (registration date: 2022-03-01, registration number: IRCT20090117001556N141). Patients with MDD were randomized to receive either sertraline (100 mg/day) combined with lumateperone (42 mg/day) or sertraline (100 mg/day) with placebo. The Hamilton Depression Rating Scale (HDRS) was used to assess treatment efficacy. Fifty-eight patients with MDD were analyzed (age: 36.91 ± 9.81 and male: 69.0%). The two groups were comparable across baseline sociodemographic and clinical characteristics except for marital status. There was a significant time × treatment interaction on HDRS (P = 0.027), suggesting greater improvement in depressive symptoms following the lumateperone adjuvant therapy. Compared with the placebo group, a significantly larger proportion of individuals receiving lumateperone experienced an HDRS reduction rate greater than or equal to 50% at weeks 4 (90.0 vs. 60.7%, P = 0.014) and 8 (100 vs. 82.1, P = 0.021). However, the remission rate was not different. No serious adverse events were reported. This study suggests that lumateperone can be considered an effective and safe adjuvant treatment for MDD. Future larger clinical trials with extended follow-up periods are needed to confirm its efficacy for clinical use.

Abstract
Lumateperone is a novel antipsychotic recently approved for the treatment of schizophrenia. Its unique pharmacological profile includes modulation of serotonergic, dopaminergic, and glutamatergic neurotransmission, differentiating it from other second-generation antipsychotics. This paper explores the pharmacological features and clinical potential of lumateperone across neuropsychiatric conditions. A review of current literature, including pharmacokinetic and pharmacodynamic studies, was conducted. It focused on lumateperone's mechanism of action and receptor-binding profile, and clinical trials assessing its efficacy and safety in schizophrenia and other psychiatric disorders. Lumateperone demonstrates high affinity for 5-HT2A receptors, moderate affinity for D2 receptors, and low affinity for H1 and 5-HT2C receptors. It acts as a presynaptic D2 agonist and a postsynaptic antagonist, contributing to a favorable side-effect profile with reduced extrapyramidal symptoms. Clinical trials suggest that lumateperone is effective in reducing both positive and negative symptoms of schizophrenia, with minimal metabolic and cardiovascular risks. It is also being explored as an adjunctive therapy for major depressive disorder and bipolar depression. Lumateperone presents a promising therapeutic option for schizophrenia with a novel mechanism of action and a favorable safety profile. Its potential application in other psychiatric conditions warrants further investigation, particularly in treatment-resistant populations.

PET clinical study of novel antipsychotic LB-102 demonstrates unexpectedly prolonged dopamine receptor target engagement. Neuropsychopharmacology 2024; 50:372-377. [PMID: 39414986 PMCID: PMC11632090 DOI: 10.1038/s41386-024-01951-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 07/15/2024] [Accepted: 07/26/2024] [Indexed: 10/18/2024]
Abstract
Regulation of dopamine activity has important clinical consequences, most notably in schizophrenia. LB-102, N-methyl amisulpride, is a novel dopamine D2/3/5-HT7 inhibitor being developed as a treatment for schizophrenia and other psychiatric disorders. The characteristic that is common to all current antipsychotics is their engagement of D2 dopamine receptors. The goal of this study was to measure the dopamine receptor occupancy of orally administered LB-102 at three different doses (50, 75, and 100 mg as single doses and 50 and 100 mg as multiple doses) and at different timepoints in healthy volunteers using positron emission tomography (PET) with 11C raclopride as a radiotracer. Results of this study (NCT04588129) showed that steady-state once daily oral dosing of 50 mg LB-102 afforded striatal dopamine occupancy (RO) in the desired 60-80% range consistently over the course of 24 h. Contrary to the often observed relationship between RO vs plasma concentrations, maximum dopamine RO significantly lagged maximum plasma concentration and showed little variability under steady state conditions. A similar phenomenon has recently been reported with a non-racemic version of amisulpride [1]. LB-102 was generally safe and well-tolerated at all doses. Results of this study were used to inform dosing in a subsequent Phase 2 clinical study in schizophrenia patients.

Abstract
BACKGROUND For psychotic disorders (i.e. schizophrenia), pharmacotherapy plays a key role in controlling acute and long-term symptoms. To find the optimal individual dose and dosage strategy, specialised tools are used. Three tools have been proven useful to personalise drug treatments: therapeutic drug monitoring (TDM) of drug levels, pharmacogenetic testing (PG), and molecular neuroimaging. METHODS In these Guidelines, we provide an in-depth review of pharmacokinetics, pharmacodynamics, and pharmacogenetics for 45 antipsychotics. Over 30 international experts in psychiatry selected studies that have measured drug concentrations in the blood (TDM), gene polymorphisms of enzymes involved in drug metabolism, or receptor/transporter occupancies in the brain (positron emission tomography (PET)). RESULTS Study results strongly support the use of TDM and the cytochrome P450 (CYP) genotyping and/or phenotyping to guide drug therapies. Evidence-based target ranges are available for titrating drug doses that are often supported by PET findings. CONCLUSION All three tools discussed in these Guidelines are essential for drug treatment. TDM goes well beyond typical indications such as unclear compliance and polypharmacy. Despite its enormous potential to optimise treatment effects, minimise side effects and ultimately reduce the global burden of diseases, personalised drug treatment has not yet become the standard of care in psychiatry.

Abstract
Schizophrenia is a devastating chronic mental health illness which includes a complex set of symptoms like hallucination, illusion and delusion, and to manage, lifelong antipsychotic medications are needed. Schizophrenia affects 1% of the population worldwide, and to date, two different classes of antipsychotics, i.e., typical and atypical antipsychotics, are available in the market, and there is an urgent need for promising antipsychotic drugs. In this review, we focus on recently approved antipsychotics and then focus on different antipsychotic drugs under clinical trials. In this review, we first focus on lumateperone in detail, which was approved in December 2019 by the Food and Drug Administration (FDA) and simultaneously modulates serotonin, glutamate and dopamine neurotransmitters and is used at doses of 10.5-, 21- and 42 mg, which show mild adverse effects like constipation, sedation, somnolence and fatigue. This review also focuses on a few more emerging antipsychotics like brexpiprazole, brilaroxazine, roluperidone, F17464, pimavanserin (ACP-103), xanomeline, BI 409306, BI 425809 and MK-8189 which are under different phase of clinical trials and might get approved soon. Brexpiprazole and brilaroxazine act on dopamine receptors, whereas xanomeline, pimavanserin and roluperidone do not act on D2 receptors and manage the symptoms. All the antipsychotic drugs covered did not show any other severe adverse effects except gastrointestinal issues and cardiometabolic risk factors. However, still rigorous clinical trials and modifications are needed to manage adverse effects, and we can expect a few antipsychotics to be on the market soon.

Effect of antipsychotics and mood stabilisers on metabolism in bipolar disorder: a network meta-analysis of randomised-controlled trials. EClinicalMedicine 2024; 71:102581. [PMID: 38618207 PMCID: PMC11015341 DOI: 10.1016/j.eclinm.2024.102581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 03/17/2024] [Accepted: 03/19/2024] [Indexed: 04/16/2024] Open
Abstract
Background Antipsychotics and mood stabilisers are gathering attention for the disturbance of metabolism. This network meta-analysis aims to evaluate and rank the metabolic effects of the commonly used antipsychotics and mood stabilisers in treating bipolar disorder (BD). Methods Registries including PubMed, Embase, Cochrane Library, Web of Science, Ovid, and Google Scholar were searched before February 15th, 2024, for randomised controlled trials (RCTs) applying antipsychotics or mood stabilisers for BD treatment. The observed outcomes were twelve metabolic indicators. The data were extracted by two reviewers independently, and confirmed by another four reviewers and a corresponding author. The above six reviewers all participated in data analyses. Data extraction was based on PRISMA guidelines, and quality assessment was conducted according to the Cochrane Handbook. Use a random effects model for data pooling. The PROSPERO registration number is CRD42023466669. Findings Together, 5421 records were identified, and 41 publications with 11,678 complete-trial participants were confirmed eligible. After eliminating possible sensitivity, risperidone ranked 1st in elevating fasting serum glucose (SUCRA = 90.7%) and serum insulin (SUCRA = 96.6%). Lurasidone was most likely to elevate HbA1c (SUCRA = 82.1%). Olanzapine ranked 1st in elevating serum TC (SUCRA = 93.3%), TG (SUCRA = 89.6%), and LDL (SUCRA = 94.7%). Lamotrigine ranked 1st in reducing HDL (SUCRA = 82.6%). Amisulpride ranked 1st in elevating body weight (SUCRA = 100.0%). For subgroup analyses, quetiapine is more likely to affect indicators of glucose metabolism among male adult patients with bipolar mania, while long-term lurasidone tended to affect glucose metabolism among female patients with bipolar depression. Among patients under 18, divalproex tended to affect glucose metabolism, with lithium affecting lipid metabolism. In addition, most observed antipsychotics performed higher response and remission rates than placebo, and displayed a similar dropout rate with placebo, while no between-group significance of rate was observed among mood stabilisers. Interpretation Our findings suggest that overall, antipsychotics are effective in treating BD, while they are also more likely to disturb metabolism than mood stabilisers. Attention should be paid to individual applicability in clinical practice. The results put forward evidence-based information and clinical inspiration for drug compatibility and further research of the BD mechanism.

Abstract
The treatment of bipolar depression is one of the most challenging needs in contemporary psychiatry. Currently, only quetiapine, olanzapine-fluoxetine combination, lurasidone, cariprazine, and recently lumateperone have been FDA-approved to treat this condition. The neurobiology of bipolar depression and the possible mechanistic targets of bipolar antidepressant therapy remain elusive. The current study investigated whether the pharmacodynamic properties of lumateperone fit into a previously developed model which was the first to be derived based on the strict combination of clinical and preclinical data. The authors performed a systematic review of the literature to identify the pharmacodynamic properties of lumateperone. The original model suggests that a constellation of effects on different receptors is necessary, but refinements, including the present study, suggest that the inhibition of the serotonin reuptake at the first level, the 5HT-2A blockade at the second level, and the norepinephrine alpha-1 receptors blockade at a third level in combination with D1 blockade contribute to the antidepressant effect in acute bipolar depression. The D2 blockade acts as a protective mechanism and reduces the risk of switching to mania/hypomania.

Longo G, Cicolini A, Orsolini L, Volpe U. The Novel Antipsychotic Lumateperone (Iti-007) in the Treatment of Schizophrenia: A Systematic Review. Brain Sci 2023; 13:1641. [PMID: 38137089 PMCID: PMC10741391 DOI: 10.3390/brainsci13121641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/18/2023] [Accepted: 11/24/2023] [Indexed: 12/24/2023] Open
Abstract
Lumateperone (also known as ITI-007 or ITI-722) represents a novel second-generation medication characterized by a favorable safety and tolerability profile. This is attributed to its notable selectivity for D2 receptors within specific regions of the brain. The U.S. Food and Drug Administration (FDA) granted approval for the treatment of schizophrenia in adults in December 2019. Additionally, it gained approval for addressing depressive episodes associated with bipolar I and II disorders in adults, either as a standalone therapy or in conjunction with lithium or valproate, in December 2021. The objective of this investigation is to systematically review the existing literature to assess the safety, tolerability, and efficacy of lumateperone in the treatment of schizophrenia. Lumateperone has demonstrated effectiveness in addressing positive, negative, and cognitive symptoms associated with schizophrenia. The evaluation of safety indicators in the reviewed studies indicates that lumateperone is deemed to be a well-tolerated and safe antipsychotic. Additional research is warranted to explore lumateperone's efficacy in managing major depressive disorders, behavioral issues in Alzheimer's disease and dementia, sleep maintenance insomnia, bipolar disorders, and personality disorders.

Abstract
This drug review provides a comprehensive analysis of a novel antipsychotic called lumateperone, marketed as Caplyta. Lumateperone gained FDA approval in 2019 for treating schizophrenia and later, in 2021, for treating bipolar depression. The review begins by delving into lumateperone's mechanism of action, which involves the partial agonism of the dopamine D2 receptor as well as its unique effects on the dopamine transporter, N-methyl-D-aspartate (NMDA) receptor, and serotonin transporter. Additionally, the study examines lumateperone's distinctive pharmacokinetics. Moreover, this review assesses lumateperone's metabolic profile and highlights its favorable outcomes regarding mean body weight, BMI, and waist circumference, surpassing those of other second-generation antipsychotic medications. The study explicitly emphasizes the efficacy and safety of lumateperone in treating schizophrenia and bipolar depression associated with bipolar I and II disorders. An extensive investigation of multiple clinical trials provides compelling evidence of lumateperone's advantages over existing antipsychotic medications. The review also acknowledges the limitations of lumateperone compared to other antipsychotics. In conclusion, this drug review underscores the importance of further research to uncover the additional limitations of lumateperone while acknowledging its promising benefits and potential for advancing treatment options.

Abstract
LB-102 is an N-methylated analogue of amisulpride under development to treat schizophrenia. LB-102 was evaluated in a Phase 1, double-blind, placebo-controlled, clinical study to evaluate safety and pharmacokinetics. This was a first-in-human study examining single and multiple doses of LB-102 administered orally in 64 healthy volunteers. Dosing in the single ascending dose (SAD) portion of the study was initially planned to be 50, 100, 200, and 400 mg, with doses in the multiple ascending dose (MAD) portion to be determined based on observations in the SAD portion. As a result of two cases of EPS (acute dystonia) at 200 mg in the MAD portion of the study, dosing of that arm was discontinued and doses for the remaining cohort were decreased to 150 mg/day. Dose escalation was guided by safety and plasma concentrations of LB-102 compared to a translational model. LB-102 was generally safe and well-tolerated, and clinical lab values were unremarkable at all doses, save for prolactin which was transiently elevated in the majority of subjects treated with LB-102; there were no clinical observations associated with the increases in prolactin elevation. There was evidence of transient QT interval prolongation at the 200 mg dose, none of which resulted in clinical observation or triggered stopping criteria. There were four instances of EPS (acute dystonia), typically associated with dopamine receptor occupancy in excess of 80%, one at 100 mg QD, one at 75 mg BID, and two at 100 mg BID. A phase 2 clinical study of LB-102 in schizophrenia patients with PANSS as primary endpoint is being planned.

Abstract
Lumateperone is a novel drug approved for the treatment of schizophrenia in adults and depressive episodes associated with bipolar depression in adults, as monotherapy and as adjunctive therapy with lithium or valproate treatment in the United States. Lumateperone simultaneously modulates key neurotransmitters, such as serotonin, dopamine, and glutamate, implicated in serious mental illness. In patients with schizophrenia, lumateperone was shown to improve positive symptoms along with negative and depressive symptoms, while also enhancing prosocial behavior. Moreover, in patients with bipolar I or II disorder, lumateperone improved depressive symptoms as well. To further understand the mechanisms related to lumateperone's clinical response, the aim of this study was to investigate the effect of lumateperone on dopaminergic- and glutamatergic signaling in the rat medial prefrontal cortex (mPFC). We used the conditioned avoidance response (CAR) test to determine the antipsychotic-like effect of lumateperone, electrophysiology in vitro to study lumateperone's effects on NMDA- and AMPA-induced currents in the mPFC, and the neurochemical techniques microdialysis and amperometry to measure dopamine- and glutamate release in the rat mPFC. Our results demonstrate that lumateperone; i) significantly suppressed CAR in rats, indicating an antipsychotic-like effect, ii) facilitated NMDA and AMPA receptor-mediated currents in the mPFC, in a dopamine D1-dependent manner, and iii) significantly increased dopamine and glutamate release in the rat mPFC. To the extent that these findings can be translated to humans, the ability of lumateperone to activate these pathways may contribute to its demonstrated effectiveness in safely improving symptoms related to neuropsychiatric disorder including mood alterations.

Abstract
PURPOSE Recent studies have shown that standard compartmental models using plasma input or the cerebellum reference tissue input are generally not reliable for quantifying tau burden in dynamic 18F-flortaucipir PET studies of Alzheimer disease. So far, the optimal reference region for estimating 18F-flortaucipir delivery and specific tau binding has yet to be determined. The objective of the study is to improve 18F-flortaucipir brain tau PET quantification using a spatially constrained kinetic model with dual reference tissues. METHODS Participants were classified as either cognitively normal (CN) or cognitively impaired (CI) based on clinical assessment. T1-weighted structural MRI and 105-min dynamic 18F-flortaucipir PET scans were acquired for each participant. Using both a simplified reference tissue model (SRTM2) and Logan plot with either cerebellum gray matter or centrum semiovale (CS) white matter as the reference tissue, we estimated distribution volume ratios (DVRs) and the relative transport rate constant R1 for region of interest-based (ROI) and voxelwise-based analyses. Conventional linear regression (LR) and LR with spatially constrained (LRSC) parametric imaging algorithms were then evaluated. Noise-induced bias in the parametric images was compared to estimates from ROI time activity curve-based kinetic modeling. We finally evaluated standardized uptake value ratios at early phase (SUVREP, 0.7-2.9 min) and late phase (SUVRLP, 80-105 min) to approximate R1 and DVR, respectively. RESULTS The percent coefficients of variation of R1 and DVR estimates from SRTM2 with spatially constrained modeling were comparable to those from the Logan plot and SUVRs. The SRTM2 using CS reference tissue with LRSC reduced noise-induced underestimation in the LR generated DVR images to negligible levels (< 1%). Inconsistent overestimation of DVR in the SUVRLP only occurred using the cerebellum reference tissue-based measurements. The CS reference tissue-based DVR and SUVRLP, and cerebellum-based SUVREP and R1 provided higher Cohen's effect size d to detect increased tau deposition and reduced relative tracer transport rate in CI individuals. CONCLUSION Using a spatially constrained kinetic model with dual reference tissues significantly improved quantification of relative perfusion and tau binding. Cerebellum and CS are the suggested reference tissues to estimate R1 and DVR, respectively, for dynamic 18F-flortaucipir PET studies. Cerebellum-based SUVREP and CS-based SUVRLP may be used to simplify 18F-flortaucipir PET study.

Abstract
Schizophrenia is a devastating mental disorder resulting in marked morbidity and mortality despite the optimal use of all currently available interventions. For this reason, the release of lumateperone (CaptylaR), also known as ITI-007, an orally administered, atypical antipsychotic provided a welcome novel tool for clinicians to utilize precision medicine to tailor an optimal treatment plan to the specific needs of each person with schizophrenia. To generate a foundation for clinicians to assess the risks and benefits of lumateperone in relation to other interventions for schizophrenia, we conducted a search of items for 'ITI-007' and 'lumateperone' on PubMed, ScienceDirect, Web of Science, Google Scholar, and www.clinicaltrials.gov. We present a critical evaluation of the limited information about lumateperone for schizophrenia, its use approved by the US Food and Drug Administration. Lumateperone merits consideration for patients with treatment-resistant schizophrenia and for patients with schizophrenia who are vulnerable to developing metabolic dysfunction and movement disorders. On the other hand, lumateperone should not be used for (a) women who are pregnant or breastfeeding, children, adolescents, and elderly patients with dementia-related psychosis, (b) patients who are at risk for cerebrovascular diseases, (c) patients who use inducers and moderate or strong inhibitors of the cytochrome P450-3A4 (CYP3A4) isozyme, and (d) patients who use alcohol and other sedating agents. Clinical trials from multiple centers without financial conflicts of interest to market lumateperone are needed to directly compare and contrast lumateperone and other antipsychotic agents to generate trustworthy evidence to be assessed objectively by clinicians treating patients with schizophrenia. Future investigations will provide the foundations to identify the evidence for comprehensive evaluations of the role of lumateperone in the treatment of people with schizophrenia and other conditions.

Abstract
BACKGROUND Lumateperone is a mechanistically novel agent FDA-approved for the treatment of schizophrenia. Efficacy and favorable tolerability of lumateperone were demonstrated in 2 short-term placebo-controlled studies in patients with schizophrenia. This open-label study investigated the short-term safety/tolerability of lumateperone in outpatients with stable schizophrenia switched from previous antipsychotic treatment. METHODS Adult outpatients with stable schizophrenia were switched from previous antipsychotics to lumateperone 42 mg once daily for six weeks, then patients were switched back to previous or another approved antipsychotic for 2 weeks. The primary objective assessed adverse events (AE), vital signs, laboratory tests, and extrapyramidal symptoms (EPS). Schizophrenia symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS). RESULTS Among 301 patients switched to lumateperone (study completion=71.2%), treatment-emergent AEs (TEAEs) occurred in 137 patients (45.5%), with 92 (30.6%) experiencing a drug-related TEAE. The most common drug-related TEAEs were somnolence (6.6%), headache (5.3%), and dry mouth (5.3%). Most TEAEs were mild or moderate in severity. EPS-related TEAEs were rare (1.0%). There were significant decreases from previous antipsychotics baseline in total cholesterol (P<.01), low-density lipoprotein cholesterol (P<.05), body weight (P<.01), and prolactin (P<.01); most of these parameters worsened within 2 weeks of resuming other antipsychotic treatment. PANSS Total scores remained stable relative to previous antipsychotics baseline during lumateperone treatment. CONCLUSIONS In outpatients with stable schizophrenia, lumateperone was well tolerated with low risk of cardiometabolic and EPS adverse effects and stably maintained or improved schizophrenia symptoms. These data further support the safety, tolerability, and effectiveness of lumateperone in patients with schizophrenia.

Abstract
Lumateperone (Caplyta®) is a novel, orally available agent developed by Intra-Cellular Therapies (under a license from Bristol-Myers Squibb) for the treatment of schizophrenia and other neuropsychiatric and neurological disorders. Lumateperone is a first-in-class selective and simultaneous modulator of serotonin, dopamine and glutamate. In December 2019, lumateperone received its first global approval in the USA for the treatment of schizophrenia in adults. The drug is also under clinical development for bipolar depression, behavioural disorders associated with dementia and Alzheimer's disease, sleep maintenance insomnia and major depressive disorders. This article summarizes the milestones in the development of lumateperone leading to this first approval for the treatment of schizophrenia.

Abstract
Introduction Schizophrenia is a severe psychotic disorder that is diagnosed by the presence of hallucinations or delusions along with disorganized speech, disorganized thought, or negative symptoms that are present for at least six months. Roughly 1 in 10,000 people a year are diagnosed with this psychiatric disorder. It is a chronic disorder requiring a lifetime of treatment of which antipsychotics have been the mainstay of this treatment. First-generation antipsychotics have dystonia, parkinsonism, and development of Tardive Dyskinesia as major side effects, and they are also nonspecific in terms of their actions. Second Generation antipsychotics target more specific dopamine and sometimes serotonin receptors with less dystonic side effects; however, there are additional concerns for the development of metabolic syndrome. This review aims to look at new medication on the market, lumateperone, for the treatment of Schizophrenia. Recent studies In one four week study with 60mg and 120mg of Lumateperone compared, 4mg of Risperdal, and a placebo found that Lumateperone significantly decreased the total Positive and Negative Syndrome Scale (PANSS) from baseline. Safety analysis of this study also found that Lumateperone was not associated with EPS or significant weight gain. Another study found that 42mg of Lumateperone significantly decreased PANSS score over placebo and 28mg of Lumateperone with associated TEAEs of somnolence, sedation, fatigue, and constipation. In an open-label safety, patients were switched from their current antipsychotic to Lumateperone and then switched back to their previous treatment after six weeks. PATIENTS were found to have statistically significant improvements in metabolic parameters, weight, and endocrine parameters, which were all lost when they were switched back to their previous treatment and their schizophrenic symptoms at pre-trial levels or improved them while on Lumateperone. In a continuation of the previous study over 12 months, 4 TEAEs occurred in 5% or more of the participants: diarrhea, dry mouth, weight decrease, and headache. Prolactin, metabolic labs, BMI, and weight all decreased as compared to the standard of care. Pooled studies revealed EPS related TEAEs were less frequent in patients receiving 42 mg lumateperone over Risperdal. Another pooled study looked at the safety profile; they found patients treated with lumateperone, two TEAEs occurred at twice the placebo rate and at a rate of 5% or more: dry mouth (5% vs. 2.2%) and sedation (24.1% vs. 10.0%) though TEAE discontinuation rates were lower than with Risperdal. Summary Taken together, data from these trials suggest that lumateperone can effectively treat positive symptoms, negative symptoms, and cognitive dysfunction in schizophrenia. Lumateperone entrance to the market introduces an innovative way to treat schizophrenia featuring both a novel mechanism of action and a markedly reduced side effect profile. Further research is needed to determine the efficacy of Lumateperone in treating bipolar disorder in addition to schizophrenia.

Abstract
Amino acids (AAs) are among a handful of paramount classes of compounds innately involved in the origin and evolution of all known life-forms. Along with basic scientific explorations, the major goal of medicinal chemistry research in the area of tailor-made AAs is the development of more selective and potent pharmaceuticals. The growing acceptance of peptides and peptidomimetics as drugs clearly indicates that AA-based molecules become the most successful structural motif in the modern drug design. In fact, among 24 small-molecule drugs approved by FDA in 2019, 13 of them contain a residue of AA or di-amines or amino-alcohols, which are commonly considered to be derived from the parent AAs. In the present review article, we profile 13 new tailor-made AA-derived pharmaceuticals introduced to the market in 2019. Where it is possible, we will discuss the development form drug-candidates, total synthesis, with emphasis on the core-AA, therapeutic area, and the mode of biological activity.

CNS & NEUROLOGICAL DISORDERS DRUG TARGETS 2020; 19:243-247. [PMID: 32479249 DOI: 10.2174/1871527319666200601145653] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/28/2019] [Revised: 04/04/2020] [Accepted: 04/12/2020] [Indexed: 02/07/2023]
Abstract
Lumateperone (ITI-007) is a tosylate salt with binding affinities to receptors implicated in the therapeutic actions of antipsychotic medications, including the serotonin 5HT2A receptors, dopamine D2 and D1 receptors and the serotonin transporter. It has a unique mechanism of action because it simultaneously modulates serotonin, dopamine, and glutamate neurotransmission, implicated in serious mental illness. It can be considered a multi-target-directed ligand and a multifunctional modulator of serotoninergic system with possible precognitive, antipsychotic, antidepressant and anxiolytic properties. Lumateperone has been investigated as a novel agent for the treatment of schizophrenia, but it represents a new potential option for other psychiatric and neurological diseases, such as behavioural symptoms of dementia or Alzheimer's disease, sleep disturbances, bipolar depression. Besides, it has demonstrated a favourable safety profile without significant extrapyramidal side effects, hyperprolactinemia or changes in cardiometabolic or endocrine factors versus placebo. Additional studies are warranted to confirm and examine the benefit of lumateperone and possible therapeutic targets. This paper is a comprehensive and thorough summary of the most important findings and potential future role of this particular compound in personalized treatments.

Abstract
Along with cognitive decline, 90% of patients with dementia experience behavioral and psychological symptoms of dementia, such as psychosis, aggression, agitation, and depression. Atypical antipsychotics are commonly prescribed off-label to manage certain symptoms, despite warnings from the regulatory agencies regarding the increased risk of mortality associated with their use in elderly patients. Moreover, these compounds display a limited clinical efficacy, mostly owing to the fact that they were developed to treat schizophrenia, a disease characterized by neurobiological deficits. Thus, to improve clinical efficacy, it has been suggested that patients with dementia should be treated with exclusively designed and developed drugs that interact with pharmacologically relevant targets. Within this context, numerous studies have suggested druggable targets that might achieve therapeutically acceptable pharmacological profiles. Based on this, several different drug candidates have been proposed that are being investigated in clinical trials for behavioral and psychological symptoms of dementia. We highlight the recent advances toward the development of therapeutic agents for dementia-related psychosis and agitation/aggression and discuss the relationship between the relevant biological targets and their etiology. In addition, we review the compounds that are in the early stage of development (discovery or preclinical phase) and those that are currently being investigated in clinical trials for dementia-related psychosis and agitation/aggression. We also discuss the mechanism of action of these compounds and their pharmacological utility in patients with dementia.

Abstract
Introduction: Schizophrenia, a devastating disorder with onset in adolescence or young adulthood, afflicts 1% of the population leading to severe social, educational, and occupational impairments. Lumateperone is a first-in-class investigational drug under development for the treatment of multiple neuropsychiatric and neurodegenerative disorders including schizophrenia. Its unique receptor affinity profile together with synergistic modulation of serotonergic, glutamatergic, and dopaminergic pathways imparts efficacy over a broad-spectrum of symptoms associated with schizophrenia.Areas covered: This narrative drug evaluation includes a review of lumateperone tosylate (lumateperone, ITI-007, ITI-722, Intra-Cellular Therapies, Inc.) for patients with schizophrenia. This review describes the receptor affinity profile, pharmacodynamics, pharmacokinetics, distribution, metabolism, and clinical trials that address how lumateperone could potentially emerge as an important therapeutic option for schizophrenia patients.Expert opinion: The unique pharmacological properties of lumateperone may provide the key to dramatically ameliorate the symptoms of schizophrenia as indicated by some clinical trials. Future clinical trials may be enhanced by the administration of more comprehensive long-term behavioral measures and utilization of molecular imaging to confirm the target engagement of the many possible sites of action. The results of ongoing and future studies will provide the evidence to determine if lumateperone will revolutionize the therapy of schizophrenia.

Dopamine D 2 receptor occupancy of lumateperone (ITI-007): a Positron Emission Tomography Study in patients with schizophrenia. Neuropsychopharmacology 2019; 44:598-605. [PMID: 30449883 PMCID: PMC6333832 DOI: 10.1038/s41386-018-0251-1] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 10/05/2018] [Accepted: 10/19/2018] [Indexed: 12/20/2022]
Abstract
Dopamine D2 receptor occupancy (D2RO) is a key feature of all currently approved antipsychotic medications. However, antipsychotic efficacy associated with high D2RO is often limited by side effects such as motor disturbances and hyperprolactinemia. Lumateperone (ITI-007) is a first-in-class selective and simultaneous modulator of serotonin, dopamine and glutamate in development for the treatment of schizophrenia and other disorders. The primary objective of the present study was to determine D2RO at plasma steady state of 60 mg ITI-007, a dose that previously demonstrated antipsychotic efficacy in a controlled trial, administered orally open-label once daily in the morning for two weeks in patients with schizophrenia (N = 10) and after at least a two-week washout period from standard of care antipsychotics. D2RO was determined using positron emission tomography with 11C-raclopride as the radiotracer. Mean peak dorsal striatal D2RO was 39% at 60 mg ITI-007 occurring 1 h post-dose. Lumateperone was well-tolerated with a favorable safety profile in this study. There were no clinically significant changes in vital signs, ECGs, or clinical chemistry laboratory values, including prolactin levels. There were no adverse event reports of akathisia or other extrapyramidal motor side effects; mean scores on motor function scales indicated no motor disturbances with lumateperone treatment. This level of occupancy is lower than most other antipsychotic drugs at their efficacious doses and likely contributes to the favorable safety and tolerability profile of lumateperone with reduced risk for movement disorders and hyperprolactinemia. If approved, lumateperone may provide a new and safe treatment option for individuals living with schizophrenia.

Abstract
Although the GABAergic benzodiazepines (BZDs) and Z-drugs (zolpidem, zopiclone, and zaleplon) are FDA-approved for insomnia disorders with a strong evidence base, they have many side effects, including cognitive impairment, tolerance, rebound insomnia upon discontinuation, car accidents/falls, abuse, and dependence liability. Consequently, the clinical use of off-label drugs and novel drugs that do not target the GABAergic system is increasing. The purpose of this review is to analyze the neurobiological and clinical evidence of pharmacological treatments of insomnia, excluding the BZDs and Z-drugs. We analyzed the melatonergic agonist drugs, agomelatine, prolonged-release melatonin, ramelteon, and tasimelteon; the dual orexin receptor antagonist suvorexant; the modulators of the α2δ subunit of voltage-sensitive calcium channels, gabapentin and pregabalin; the H1 antagonist, low-dose doxepin; and the histamine and serotonin receptor antagonists, amitriptyline, mirtazapine, trazodone, olanzapine, and quetiapine. The pharmacology and mechanism of action of these treatments and the evidence-base for the use of these drugs in clinical practice is outlined along with novel pipelines. There is evidence to recommend suvorexant and low-dose doxepin for sleep maintenance insomnia; there is also sufficient evidence to recommend ramelteon for sleep onset insomnia. Although there is limited evidence for the use of the quetiapine, trazodone, mirtazapine, amitriptyline, pregabalin, gabapentin, agomelatine, and olanzapine as treatments for insomnia disorder, these drugs may improve sleep while successfully treating comorbid disorders, with a different side effect profile than the BZDs and Z-drugs. The unique mechanism of action of each drug allows for a more personalized and targeted medical management of insomnia.

Abstract
INTRODUCTION Schizophrenia is a debilitating illness with a chronic impact on social function and daily living. Although various antipsychotics are available, there are still many challenges and unmet needs. Thus, many compounds with diverse mechanisms have been investigated, but all approved antipsychotics still require interactions with dopamine D2 receptors. Areas covered: We searched for investigational drugs using the key words 'dopamine' and 'schizophrenia' in American and European clinical trial registers (clinicaltrials.gov; clinicaltrialsregister.eu). Published articles were searched in PubMed, Embase, Medline, PsycINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Web of Science and the Cochrane Central Register of Controlled Trials Library. Expert opinion: The prospect of developing a dopamine antagonist is hopeful. Brexpiprazole and cariprazine, which were agents listed as 'investigational dopamine antagonists,' just received FDA approval. Novel agents such as BL 1020, ITI-007, and JNJ-37822681 have solid published data available, and agents such as L-THP, Lu AF35700, S33138, and SB-773812 are under vigorous investigation. However, the expected benefits of the newly developed antagonists may not be great because they offer little enhanced efficacy for negative symptoms, cognition and functional outcomes.

Abstract
BACKGROUND An urgent need exists for new treatments of schizophrenia that are effective against a broad range of symptoms and free of limiting safety issues. ITI-007 is a new molecular entity with a pharmacologic profile that combines dose-related monoamine modulation with phosphorylation of intracellular signaling proteins. METHODS A phase II randomized, double-blind, placebo-controlled, and active-controlled trial was conducted at eight sites in the United States with randomization of 335 acutely psychotic adults with schizophrenia. ITI-007 (60 mg and 120 mg), placebo, and risperidone, included for assay sensitivity, were evaluated as monotherapy for 4 weeks. The primary outcome measure was the Positive and Negative Syndrome Scale total score, with secondary analyses conducted on symptom subscales. RESULTS ITI-007 60 mg (p = .017, effect size = .4) and risperidone (p = .013, effect size = .4) demonstrated antipsychotic efficacy superiority over placebo on the primary end point. The results of secondary analyses reflected improvements in negative and depressive symptoms by ITI-007 60 mg. ITI-007 120 mg did not separate from placebo. However, both doses of ITI-007 were well tolerated in this patient population, as evidenced by low discontinuation and adverse event rates, and were associated with a benign metabolic profile as evidenced by significantly lower levels of prolactin, fasting glucose, total cholesterol, and triglycerides than risperidone. CONCLUSIONS The mechanistically novel investigational drug ITI-007 was effective for the treatment of schizophrenia and comparable with placebo on safety measures in this trial. Secondary analyses indicated that ITI-007 improved negative and depression symptoms and might have expanded therapeutic efficacy in comparison with current antipsychotic drugs.

Abstract
ITI-007 is an investigational drug being developed for schizophrenia and other neuropsychiatric/neurodegenerative diseases. ITI-007 has a unique pharmacological profile, combining potent 5-HT2a receptor antagonism with cell-type-specific dopamine and glutamate receptor modulation, plus serotonin reuptake inhibition. At dopamine-D2 receptors, ITI-007 acts as a post-synaptic antagonist and pre-synaptic partial agonist. Additionally, ITI-007 stimulates phosphorylation of glutamatergic NMDA-NR2B receptors, downstream of dopamine-D1 receptor intracellular signaling. Based on a large, placebo and risperidone controlled, Phase-II trial, ITI-007 60 mg was shown to be effective in reducing symptoms in patients with acutely exacerbated schizophrenia. The antipsychotic efficacy of ITI-007 60 mg in this patient population was confirmed in a recently completed Phase III study. ITI-007 was associated with minimal safety risk compared to risperidone (Phase II study) or placebo (both studies) for neuromotor disturbances, prolactin changes, weight gain and metabolic abnormalities. A second 6-week, placebo and risperidone-controlled Phase-III trial in acutely exacerbated schizophrenia is ongoing.

Abstract
Schizophrenia is a chronic and debilitating neuropsychiatric disorder affecting approximately 1% of the world's population. This disease is associated with considerable morbidity placing a major financial burden on society. Antipsychotics have been the mainstay of the pharmacological treatment of schizophrenia for decades. The traditional typical and atypical antipsychotics demonstrate clinical efficacy in treating positive symptoms, such as hallucinations and delusions, while are largely ineffective and may worsen negative symptoms, such as blunted affect and social withdrawal, as well as cognitive function. The inability to treat these latter symptoms may contribute to social function impairment associated with schizophrenia. The dysfunction of multiple neurotransmitter systems in schizophrenia suggests that drugs selectively targeting one neurotransmission pathway are unlikely to meet all the therapeutic needs of this heterogeneous disorder. Often, however, the unintentional engagement of multiple pharmacological targets or even the excessive engagement of intended pharmacological targets can lead to undesired consequences and poor tolerability. In this article, we will review marketed typical and atypical antipsychotics and new therapeutic agents targeting dopamine receptors and other neurotransmitters for the treatment of schizophrenia. Representative typical and atypical antipsychotic drugs and new investigational drug candidates will be systematically reviewed and compared by reviewing structure-activity relationships, pharmacokinetic properties, drug metabolism and safety, pharmacological properties, preclinical data in animal models, clinical outcomes and associated side effects.
