Abstract
Latuda® is a novel antipsychotic drug for schizophrenia and bipolar depression. A bioequivalence trial was performed to investigate the bioequivalence of Latuda® and its generic drug lurasidone. Two independent trials were carried out, each involving 28 subjects. In the fasting trial, subjects were randomly assigned to two groups (1:1 ratio), receiving either 40 mg of generic lurasidone or Latuda®. After a 7-day washout period, subjects entered the second period with a crossover administration of 40 mg of generic lurasidone or Latuda®. The postprandial study design was similar to that of the fasting study. In the fasting study, the pharmacokinetic (PK) parameter values of generic lurasidone and Latuda® were as follows: the Cmax was 28.84 ± 19.34 ng/ml and 28.22 ± 21.19 ng/ml, respectively; the AUC0-t was 121.39 ± 58.47 h*ng/ml and 118.35 ± 52.24 h*ng/ml, respectively; and the AUC0-∞ was 129.63 ± 63.26 h*ng/ml and 126.59 ± 57.99 h*ng/ml, respectively. The primary pharmacokinetic parameter, Cmax, was assessed for equivalence using reference-scaled average bioequivalence (RSABE), while other parameters (AUC0-t, AUC0-∞) were evaluated using average bioequivalence (ABE). The results indicate that both Cmax and AUC meet the equivalence criteria. In the postprandial study, the PK values of generic lurasidone and Latuda® were as follows: the Cmax was 74.89 ± 32.06 ng/ml and 83.51 ± 33.52 ng/ml, respectively; the AUC0-t was 274.77 ± 103.05 h*ng/ml and 289.26 ± 95.25 h*ng/ml, respectively; and the AUC0-∞ was 302.44 ± 121.60 h*ng/ml and 316.32 ± 109.04 h*ng/ml, respectively. The primary pharmacokinetic parameters (Cmax, AUC0-t, AUC0-∞) were assessed for equivalence using ABE, and both met the equivalence criteria. In the study, lurasidone and Latuda® both exhibited acceptable safety and tolerability. The results displayed that lurasidone and Latuda® were bioequivalent and safe in healthy Chinese participants. Clinical Trial Registry: This trial is registered at chinadrugtrials.org.cn (no.: CTR20191717, date: 2019.08.29).

Abstract
Exposure to stressful experiences accounts for almost half of the risk for mental disorders. Hence, stress-induced alterations represent a key target for pharmacological interventions aimed at restoring brain function in affected individuals. We have previously demonstrated that lurasidone, a multi-receptor antipsychotic drug approved for the treatment of schizophrenia and bipolar depression, can normalize the functional and molecular impairments induced by stress exposure, representing a valuable tool for the treatment of stress-induced mental illnesses. However, the mechanisms that may contribute to the therapeutic effects of lurasidone are still poorly understood. Here, we performed a transcriptomic analysis on the prefrontal cortex (PFC) of adult male rats exposed to the chronic mild stress (CMS) paradigm and we investigated the impact of chronic lurasidone treatment on such changes. We found that CMS exposure leads to an anhedonic phenotype associated with a down-regulation of different pathways associated to neuronal guidance and synaptic plasticity within the PFC. Interestingly, a significant part of these alterations (around 25%) were counteracted by lurasidone treatment. In summary, we provided new insights on the transcriptional changes relevant for the therapeutic intervention with lurasidone, which may ultimately promote resilience.

A Novel Method for Deriving Adverse Event Prevalence in Randomized Controlled Trials: Potential for Improved Understanding of Benefit-Risk Ratio and Application to Drug Labels.

Abstract
INTRODUCTION Adverse event (AE) data in randomized controlled trials (RCTs) allow quantification of a drug's safety risk relative to placebo and comparison across medications. The standard US label for Food and Drug Administration-approved drugs typically lists AEs by MedDRA Preferred Term that occur at ≥ 2% in drug and with greater incidence than in placebo. We suggest that the drug label can be more informative for both patients and physicians if it includes, in addition to AE incidence (percent of subjects who reported the AE out of the total subjects in treatment), the absolute prevalence (percent of subject-days spent with an AE out of the total subject-days spent in treatment) and expected duration (days required for AE incidence to be reduced by half). We also propose a new method to analyze AEs in RCTs using drug-placebo difference in AE prevalence to improve safety signal detection. METHODS AE data from six RCTs in schizophrenia were analyzed (five RCTs of the dopamine D2 receptor-based antipsychotic lurasidone and one RCT of the novel trace amine-associated receptor 1 [TAAR1] agonist ulotaront). We determined incidence, absolute prevalence, and expected duration of AEs for lurasidone and ulotaront vs respective placebo. We also calculated areas under the curve of drug-placebo difference in AE prevalence and mean percent contribution of each AE to this difference. RESULTS A number of AEs with the same incidence had different absolute prevalence and expected duration. When accounting for these two parameters, AEs that did not appear in the 2% incidence tables of the drug label turned out to contribute substantially to drug tolerability. The percent contribution of a drug-related AE to the overall side effect burden increased the drug-placebo difference in AE prevalence, whereas the percent contribution of a placebo-related AE decreased such difference, revealing a continuum of risk between drug and placebo. AE prevalence curves for drug were generally greater than those for placebo. Ulotaront exhibited a small drug-placebo difference in AE prevalence curves due to a relatively low incidence and short duration of AEs in the ulotaront treatment arm as well as the emergence of disease-related AEs in the placebo arm. CONCLUSION Reporting AE absolute prevalence and expected duration for each RCT and incorporating them in the drug label is possible, is clinically relevant, and allows standardized comparison of medications. Our new metric, the drug-placebo difference in AE prevalence, facilitates signal detection in RCTs. We piloted this metric in RCTs of several neuropsychiatric indications and drugs, offering a new way to compare AE burden and tolerability among treatments using existing clinical trial information.

Abstract
The aim of this study was to investigate the impacts of 24 variants of recombinant human CYP3A4 and drug interactions on the metabolism of lurasidone. In vitro, enzymatic reaction incubation system of CYP3A4 was established to determine the kinetic parameters of lurasidone catalyzed by 24 CYP3A4 variants. Then, we constructed rat liver microsomes (RLM) and human liver microsomes (HLM) incubation system to screen potential anti-tumor drugs that could interact with lurasidone and studied its inhibitory mechanism. In vivo, Sprague-Dawley (SD) rats were applied to study the interaction between lurasidone and olmutinib. The concentrations of the analytes were detected by ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). As the results, we found that compared with the wild-type CYP3A4, the relative intrinsic clearances vary from 355.77 % in CYP3A4.15 to 14.11 % in CYP3A4.12. A series of drugs were screened based on the incubation system, and compared to without olmutinib, the amount of ID-14283 (the metabolite of lurasidone) in RLM and HLM were reduced to 7.22 % and 7.59 %, and its IC50 were 18.83 ± 1.06 μM and 16.15 ± 0.81 μM, respectively. At the same time, it exerted inhibitory effects both through a mixed mechanism. When co-administration of lurasidone with olmutinib in rats, the AUC(0-t) and AUC(0-∞) of lurasidone were significantly increased by 73.52 % and 69.68 %, respectively, while CLz/F was observably decreased by 43.83 %. In conclusion, CYP3A4 genetic polymorphism and olmutinib can remarkably affect the metabolism of lurasidone.

Abstract
BACKGROUND Schizophrenia is a psychiatric disorder characterized by chronic or recurrent symptoms. Lurasidone was licensed in China in 2019 for the treatment of adult schizophrenia in adults with a maximum dose of 80 mg/d. However, post-market surveillance (PMS) with an adequate sample size is required for further validation of the drug’s safety profile and effectiveness.
AIM To conduct PMS in real-world clinical settings and evaluate the safety and effectiveness of lurasidone in the Chinese population.
METHODS A prospective, multicenter, open-label, 12-wk surveillance was conducted in mainland China. All patients with schizophrenia from 10 sites who had begun medication with lurasidone between September 2019 and August 2022 were eligible for enrollment. Safety assessments included adverse events (AEs), adverse drug reactions (ADRs), extrapyramidal symptoms (EPS), akathisia, use of EPS drugs, weight gain, and laboratory values as metabolic parameters and the QTc interval. The effectiveness was assessed using the brief psychiatric rating scale (BPRS) from baseline to the end of treatment.
RESULTS A total of 965 patients were enrolled in the full analysis set and 894 in the safety set in this interim analysis. The average daily dose was 61.7 ± 19.08 mg (mean ± SD) during the treatment. AEs and ADRs were experienced by 101 patients (11.3%) and 78 patients (8.7%), respectively, which were mostly mild. EPS occurred in 25 individuals with a 2.8% incidence, including akathisia in 20 individuals (2.2%). Moreover, 59 patients received drugs for treating EPS during the treatment, with an incidence of 6.6% which dropped to 5.4% at the end of the treatment. The average weight change was 0.20 ± 2.36 kg (P = 0.01687) with 0.8% of patients showing a weight gain of ≥ 7% at week 12 compared with that at the baseline. The mean values of metabolic parameters and the QTc interval at baseline and week 12 were within normal ranges. The mean changes in total BPRS scores were -8.9 ± 9.76 (n = 959), -13.5 ± 12.29 (n = 959), and -16.8 ± 13.97 (n = 959) after 2/4, 6/8, and 12 wk, respectively (P < 0.001 for each visit compared with the baseline) using the last-observation-carried-forward method.
CONCLUSION The interim analysis of the PMS of adult patients with schizophrenia demonstrate the safety and effectiveness of lurasidone in the Chinese population. No new safety or efficacy concerns were identified.

Abstract
Lurasidone is a second-generation antipsychotic drug used to treat schizophrenia, mania, and bipolar disorder. The drug is an antagonist of the 5-HT2A and D2 receptors. No effect of lurasidone on the voltage-gated K+ (Kv) channels has yet been identified. Here, we show that lurasidone inhibits the vascular Kv channels of rabbit coronary arterial smooth muscle cells in a dose-dependent manner with an IC50 of 1.88 ± 0.21 μM and a Hill coefficient of 0.98 ± 0.09. Although lurasidone (3 μM) did not affect the activation kinetics, the drug negatively shifted the inactivation curve, suggesting that the drug interacted with the voltage sensors of Kv channels. Application of 1 or 2 Hz train steps in the presence of lurasidone significantly increased Kv current inhibition. The recovery time after channel inactivation increased in the presence of lurasidone. These results suggest that the inhibitory action of lurasidone is use (state)-dependent. Pretreatment with a Kv 1.5 subtype inhibitor effectively reduced the inhibitory effect of lurasidone. However, the inhibitory effect on Kv channels did not markedly change after pretreatment with a Kv 2.1 or a Kv7 subtype inhibitor. In summary, lurasidone inhibits vascular Kv channels (primarily the Kv1.5 subtype) in a concentration- and use (state)-dependent manner by shifting the steady-state inactivation curve.

Abstract
Somnolence is a common adverse effect of antipsychotic drugs used to treat psychotic disorders. It causes problems in many areas of life, such as gainful employment, driving, childcare, and social interactions. Somnolence is a major problem for a relatively new antipsychotic drug, lurasidone, whose dose-effect relationship remains unclear. Based on data from a bioequivalence study of two 40 mg lurasidone hydrochloride tablets, we designed two case-control studies to explore the correlation between somnolence and exposure to lurasidone and determine the factors associated with lurasidone-induced somnolence. In the first case-control study, lurasidone was administered to healthy volunteers; 30 experienced somnolence (as pre-defined) but 29 did not. Moreover, plasma concentration at 1 h was significantly associated with somnolence (OR = 1.124; p = 0.001). In the second case-control study, 48 volunteers administered lurasidone were classified into somnolence and no-somnolence groups based on different time-related criteria. We observed a positive association between plasma concentration at 0.75 h and somnolence (OR = 1.024; p = 0.002). Receiver operating characteristic analysis revealed that a plasma lurasidone concentration >21.65 ng/mL 1 h after administration strongly predicted somnolence. Our findings in healthy volunteers need to be further validated in patients in clinical settings to determine the optimal dose and duration of lurasidone administration.

To date, tachycardia and orthostatic hypotension have been reported as one of the negative cardiovascular complications of antipsychotics. The aim of this study was to report a case of sinus bradycardia caused by the addition of lurasidone. The patient, a 46-year-old bipolar disorder female, was admitted to the Affiliated Brain Hospital of Guangzhou Medical University with 28 years of alternating euphoric and dysphoria. On the basis of lithium carbonate 1,200 mg/day and sodium valproate 1,500 mg/day, the patient was given lurasidone 80 mg/day. After 5 days of medication, her heart rate (HR) became 48 beats per minute (beats/min). As a result, lurasidone treatment was held. On 5th day after discontinuing lurasidone, the HR reached 80 beats/min. This case report notifies that although the cardiovascular effects of lurasidone are not significant, it is also important to monitor HR status after the first administration of lurasidone.

Abstract
BACKGROUND The efficacy and safety of lurasidone monotherapy in patients with bipolar I depression with or without rapid cycling has not been previously investigated. METHODS We performed subgroup analysis (rapid cycling/non-rapid cycling) of pooled data from two 6-week, randomized, double-blind, placebo-controlled trials of lurasidone monotherapy (20-60 mg/day or 80-120 mg/day). Analyses included mean change from baseline to week 6 in Montgomery-Åsberg Depression Rating Scale (MADRS) total score. Safety assessments included the number of treatment-emergent adverse events (TEAEs) and laboratory assessments. RESULTS Of 1024 patients randomized, 85 were rapid cycling. Mean change in MADRS total score in patients with non-rapid cycling and rapid cycling, respectively, was -14.8 (effect size = 0.47) and - 12.8 (effect size = 0.04) in the lurasidone 20-60 mg/day group, -14.3 (effect size = 0.41) and - 13.0 (effect size = 0.02) in the lurasidone 80-120 mg/day group and -10.6 and -13.3 in the placebo group. The most common TEAE in each subgroup was akathisia in both lurasidone groups. Treatment-emergent mania was reported only in a small number of rapid cycling and non-rapid cycling patients. LIMITATIONS This was a post-hoc analysis of a short-term study that excluded patients with ≥8 cycles in the past year. CONCLUSIONS In patients with non-rapid cycling bipolar depression, lurasidone monotherapy significantly improved depressive symptoms relative to placebo at both the 20-60 mg/day and 80-120 mg/day doses. In patients with rapid cycling, both doses of lurasidone displayed depressive symptom score reduction from baseline, but significant improvement was not observed likely due to high levels of improvement on placebo and small sample size.

Abstract
Latuda® is an oral tablet approved by the US Food and Drug Administration (FDA) for the treatment of schizophrenia. However, the clinical efficacy of Latuda® is compromised by patient noncompliance due to frequent daily administration, especially for patients experiencing severe schizophrenia, whose medication is often needed for several months to years. Hence, developing a long-acting injectable formulation of lurasidone is urgently needed. Herein, a poorly water-soluble lurasidone pamoate (LP) salt was synthesized via the facile ion pair-based salt formation technology. The solubility of LP was decreased by 233 folds compared with that of lurasidone hydrochloride (LH). Furthermore, suspensions of LH and LP with three different particle sizes, including 400 nm small-sized nanocrystals (SNCs), 4 μm medium-sized microcrystals (MMCs), and 15 μm large-sized microcrystals (LMCs) were prepared and characterized by powder X-ray diffraction (PXRD) and differential scanning calorimetry (DSC). The in vitro release results showed that particle sizes had great effects on the sustained release of LH, where large-sized particles exhibited superior sustained release than the smaller ones. Besides, LP suspensions exhibited better sustained release than LH suspensions at the same size scale. Moreover, the pharmacokinetics showed that LP LMCs produced an extended in vivo intramuscularly injectable profile for up to 45 days, which was 10 days longer than that of the LH LMCs. Our findings demonstrated that particle size had appreciable impacts on drug sustained release and provided valuable knowledge for the rational design of optimized micronized suspensions for long-acting injectables.

Abstract
BACKGROUND Tardive sensory syndrome (TSS) is a subtype of tardive syndrome (TS), and its etiology is still uncertain. Lurasidone is an atypical antipsychotic that has high affinity for dopamine D2- and serotonergic 5HT2A- and 5-HT7-receptors.
CASE SUMMARY A 52-year-old woman, previously diagnosed with schizophrenia, and with no history of movement disorders and no sensory paresthesia, had taken lurasidone, initiate dose 40 mg daily then up titration to 120 mg daily, since March 2021, and developed mandibular sensory (pain) paresthesia after 3 mo of administration. After switching from lurasidone to quetiapine, she reported obvious impr-ovement in her mandibular pain.
CONCLUSION It is noteworthy that TSS is a rare subtype of TS, and lurasidone, an atypical antipsychotic, usually has a lower risk of causing TS. In light of the temporal relationship, it is therefore concluded that use of lurasidone might have caused TSS in this patient. We reported this rare case as a reminder that clinicians should adopt a cautious approach when prescribing atypical antipsychotics, so as to prevent TS.

Abstract
RATIONALE While meta-analyses of clinical trials found that lurasidone and partial dopamine agonists (brexpiprazole and aripiprazole) were the antipsychotics less likely to cause QTc prolongation, and sertindole, amisulpride, and ziprasidone were the most frequently associated with this adverse drug reaction; no real-world studies have investigated this risk between the different antipsychotics. OBJECTIVES AND METHODS Using data recorded from 1967 to 2019 in VigiBase®, the World Health Organization's Global Individual Case Safety Reports database, we performed disproportionality analysis to investigate the risk of reporting QT prolongation between 20 antipsychotics. RESULTS Sertindole had the highest risk of reporting QT prolongation, followed by ziprasidone and amisulpride. Lurasidone was associated with the lowest risk. First-generation antipsychotics were associated with a greater QT prolongation reporting risk (ROR, 1.21; 95%CI, 1.10-1.33) than second-generation antipsychotics. A positive correlation was found between the risk of reporting QT prolongation and affinity for hERG channel (R2 = 0.14, slope = Pearson coefficient = 0.41, p value = 0.1945). CONCLUSIONS This large study in a real-world setting suggests that sertindole and ziprasidone were the antipsychotics drugs associated with the highest risk of QT prolongation reporting. Our results suggest that lurasidone is less associated with QT interval prolongation reports. Our study also suggests that antipsychotics with the higher hERG affinity are more associated with to QT prolongations reports.

Abstract
BACKGROUND AND RATIONALE Treatment persistence combines clinician and patient judgment of efficacy, tolerability and safety into a comprehensive measure of effectiveness and is defined as the act of continuing a treatment over time. Studies have reported poor treatment persistence to antipsychotic medications in patients with schizophrenia. This study evaluated treatment persistence to lurasidone (LUR) in patients with schizophrenia in a real-world Italian setting. METHODS This was a retrospective observational study of patients with schizophrenia who started treatment with LUR ≥ 6 months before inclusion. Following informed consent, data were collected starting from the index date (start of LUR treatment) at all visits occurring as per clinical practice. The primary endpoint was treatment persistence during the first 6 months, defined as the time between index date and all-cause discontinuation. Patients treated with LUR > 180 days were considered persistent. As secondary endpoint, treatment persistence was evaluated for a period of ≥ 18 months. RESULTS Forty-five patients were enrolled and 41 (91.11%) completed the study. Forty-one patients (91.11%) were included in the eligible population as they initiated LUR treatment ≥ 6 months before data collection. Patients were 43.0 ± 15.89 years old and 61% were female. Twenty-two patients (53.66%) started LUR treatment in a hospital setting and 19 (46.34%) in an outpatient setting. Based on Clinical Global Impression-Severity scale (CGI-S) at LUR initiation, 12 patients (29.27%) were severely ill, 17.07% markedly ill, 19.51% moderately ill, 2.44% mildly ill and 4.88% borderline mentally ill. Thirty-two patients (78.05%) were treatment persistent for ≥ 180 days. Among the 19 patients observed for ≥ 18 months, 11 (57.89%) were persistent for ≥ 18 months. Among the 22 study patients observed for < 18 months, 12 (54.54%) were persistent. An improvement in schizophrenia severity according to CGI-S was observed at inclusion (following LUR therapy) compared to the index date. Six patients (14.63%) experienced at least one adverse drug reaction: akathisia (7.32%), extrapyramidal disorder (4.88%), hyperprolactinemia (2.44%), restlessness (2.44%), and galactorrhea (2.44%). None were serious. CONCLUSIONS Persistence to LUR in patients with schizophrenia was relatively high: 78% and 58% of patients were still on LUR after 6 and 18 months of treatment, respectively. This may reflect LUR's relatively favorable balance between efficacy and tolerability, as well as favorable patient satisfaction and acceptance.

Abstract
BACKGROUND Schizophrenia is a serious mental health condition characterised by distortions in thought processes, perception, mood, sense of self, and behaviour. Lurasidone, a second-generation atypical antipsychotic, represents an additional treatment option alongside existing antipsychotics for adolescents and adults with schizophrenia. An economic model was developed to evaluate the incremental costs of lurasidone as a first-line treatment option compared to existing antipsychotics. METHODS A Markov model was developed to estimate the cost impact of lurasidone as a first-line treatment option for both adolescents and adults. The sequence-based model incorporated the following health states: stable (no relapse or discontinuation), discontinuation (due to adverse events or other reasons), and relapse. Data used to determine the movement of patients between health states were obtained from network meta-analyses (NMAs). The time horizon ranged from three to five years (depending on the patient population) and a six-weekly cycle length was used. Unit costs and resource use were reflective of the UK NHS and Personal Social Services and consisted of the following categories: outpatient, adverse events, primary and residential care. Extensive deterministic sensitivity analysis was undertaken to assess the level of uncertainty associated with the base case results. RESULTS Lurasidone is demonstrated to be cost-saving as a first-line treatment within the adolescent and adult populations when compared to second-line and third-line respectively. Lurasidone is more expensive in terms of treatment costs, resource use (in the stable health state) and the treatment of adverse events. However, these costs are outweighed by the savings associated with the relapse health state. Lurasidone remains cost-saving when inputs are varied in sensitivity analysis and scenario analysis. CONCLUSIONS Lurasidone is a cost-saving first-line treatment for schizophrenia for both adolescents and adults.

Abstract
Chronic stress represents a major contributor for the development of mental illness. This study aimed to investigate how animals exposed to chronic mild stress (CMS) responded to an acute stress (AS), as a vulnerability's challenge, and to establish the potential effects of the antipsychotic drug lurasidone on such mechanisms. Adult male Wistar rats were exposed or not (controls) to a CMS paradigm for 7 weeks. Starting from the end of week 2, animals were randomized to receive vehicle or lurasidone for 5 weeks. Sucrose intake was used to measure anhedonia. At the end, half of the animals were exposed to an acute stress before sacrifice. Exposure to CMS produced a significant reduction in sucrose consumption, whereas lurasidone progressively normalized such alteration. We found that exposure to AS produced an upregulation of Brain derived neurotrophic factor (Bdnf) in the prefrontal cortex of controls animals. This response was impaired in CMS rats and restored by lurasidone treatment. While in control animals, AS-induced increase of Bdnf mRNA levels was specific for Parvalbumin cells, CMS rats treated with lurasidone show a significant upregulation of Bdnf in pyramidal cells. Furthermore, when investigating the activation of different brain regions, CMS rats showed an impairment in the global response to the acute stressor, that was largely restored by lurasidone treatment. Our results suggest that lurasidone treatment in CMS rats may regulate specific circuits and mechanisms, which will ultimately contribute to boost resilience under stressful challenges.

Abstract
A part of atypical antipsychotics exert mood-stabilising effects via modulation of various monoamine receptors and intracellular signalling. Recent pharmacodynamic studies suggested that tripartite-synaptic transmission can be involved in pathophysiology of mood-disorders, schizophrenia, their associated cognitive impairments, and several adverse-reactions to atypical antipsychotics. Therefore, to explore mechanisms underlying antidepressive mood-stabilising and antipsychotic effects of lurasidone, we determined concentration-dependent effects of acute and subchronic lurasidone administrations on astroglial L-glutamate release, and expression of connexin43, ERK, AKT, adenosine monophosphate activated protein kinase (AMPK), 5-HT1A (5-HT1AR) and 5-HT7 (5-HT7R) receptors in cultured astrocytes using ultra-high-pressure liquid-chromatography with mass-spectrometry and capillary-immunoblotting systems. Therapeutically-relevant lurasidone concentration suppressed astroglial L-glutamate release through activated connexin43-containing hemichannel by decreasing connexin43 expression in plasma-membrane. Subchronic lurasidone administration downregulated 5-HT1AR and 5-HT7R in astroglial plasma-membrane concentration-dependently. Subchronic lurasidone administration attenuated ERK and AMPK signallings concentration-dependently without affecting AKT signalling. These results suggest that effects of subchronic lurasidone administration on astroglial L-glutamate release, 5-HT receptor, and intracellular signalling are similar to vortioxetine and different from mood-stabilising atypical antipsychotics, clozapine. Therefore, inhibitory effects of subchronic lurasidone administration on astroglial L-glutamate release through activated connexin43-containing hemichannel probably contribute to pathophysiology of antidepressive mood-stabilising effects of lurasidone. Furthermore, inhibitory effects of subchronic lurasidone administration on ERK and AMPK activities (without affecting AKT activity) induced by downregulation of 5-HT7R could result in clinical advantages of lurasidone, lower risk of weight gain.

Abstract
BACKGROUND There is a relative lack of long-term, prospective data evaluating the safety and effectiveness of treatment in early-onset adolescent patients with schizophrenia who are treatment-naïve. The aim of this post-hoc analysis was to examine the long-term safety and effectiveness of lurasidone in adolescents with schizophrenia who were antipsychotic treatment-naïve (TN; at the time of enrolment in the initial study) compared to adolescents treated previously (TP) with an antipsychotic. METHODS Patients aged 13-17 who completed 6 weeks of double-blind (DB), placebo-controlled treatment with lurasidone were enrolled in a 2-year, open-label (OL), flexible-dose (20-80 mg/day) lurasidone study. RESULTS The long-term analysis sample consisted of 50 TN and 221 TP patients, of whom 40% and 43%, respectively, discontinued prematurely. The three most common adverse events for TN and TP patients, respectively, were headache (26.0%, 23.5%); schizophrenia (14.0%, 12.2%), dizziness (16.0%, 4.1%), and nausea (16.0%, 11.8%). At endpoint, mean increase in weight was similar to expected weight gain based on growth charts for both TN (+4.5 kg vs. + 5.7 kg) and TP (+4.6 kg vs. + 6.6 kg) patients. Minimal changes were observed for each group in metabolic parameters and prolactin. Mean improvement was consistently greater in the TN vs. TP group (-19.2 vs. -15.9; effect size of 0.33) for between-group change in PANSS total score at Week 104. CONCLUSIONS In both TN and TP adolescents with schizophrenia, long-term treatment with lurasidone was associated with minimal effects on body weight, lipids, glycemic indices, and prolactin, with generally small differences noted in rates of reported AEs. Continued improvement in symptoms of schizophrenia was evident for both the TN and TP groups. These data indicate that lurasidone is a safe and efficacious treatment option for treatment-naïve youth with schizophrenia, who are generally most sensitive to antipsychotic adverse effects.

Abstract
RATIONALE We conducted a meta-analysis of double-blind, randomized placebo-controlled trials of lurasidone (LUR) to examine the difference in the risk ratios (RRs) for adverse events (AEs) between depressive disorders (bipolar depression and major depressive disorders) and schizophrenia. OBJECTIVES Three trials for depressive disorders (n = 1,239) were used for flexible-dose LUR 20-60 (LUR20-60) and/or 80-120 (LUR80-120) mg/day. Nine schizophrenia trials (n = 2,684) were used for fixed-dose LUR. The RRs of LUR20-60 and LUR80-120 for depressive disorders were compared with those of LUR 40 (LUR40) and LUR 80 (LUR80) mg/day for schizophrenia, respectively, to match LUR dose. RESULTS LUR20-60 caused a higher incidence of akathisia (RR = 2.28; p = 0.003) and weight gain (RR = 4.11; p = 0.05) than placebo in patients with depressive disorders, and LUR40 caused a higher incidence of akathisia (RR = 2.39; p = 0.0001), extrapyramidal symptoms (RR = 1.88; p = 0.02), anticholinergic drug use (RR = 1.58; p = 0.005), somnolence (RR = 2.19; p = 0.002), and dizziness (RR = 2.06; p = 0.05) than placebo in patients with schizophrenia. However, no significant differences in the RRs for all outcomes were found between depressive disorders and schizophrenia. LUR80-120 caused a higher incidence of akathisia (RR = 3.90; p < 0.0001), extrapyramidal symptoms (RR = 2.26; p = 0.04), anticholinergic use (RR = 4.70; p < 0.0001), and nausea (RR = 2.15; p = 0.001) than placebo in patients with depressive disorders. LUR80 caused a higher incidence of akathisia (RR = 2.99; p < 0.0001), extrapyramidal symptoms (RR = 2.55; p = 0.01), anticholinergic use (RR = 1.86; p = 0.01), somnolence (RR = 2.46; p = 0.001), and nausea (RR = 1.64; p = 0.04) than placebo in patients with schizophrenia. Depressive disorders had a higher RR for anticholinergic use than schizophrenia (p = 0.04). CONCLUSIONS The incidence of AEs did not differ between schizophrenia and depressive disorders.

Abstract
BACKGROUND Psychotropic drugs can cause neurological effects when overdosed. This study reports a case of psychotropic drugs overdose presenting with serotonin toxicity and encephalopathy. CASE PRESENTATION A 20-year-old female with major depression presented with agitation 3 h after an overdose on multiple medications. Her current medications were vortioxetine, lamotrigine, lurasidone, and bupropion (extended-release). Vital signs showed hyperthermia and tachycardia. Neurological examination was remarkable for mydriasis and hyperreflexia with inducible ankle clonus. The electrocardiography showed sinus tachycardia with QTc 480 ms. Twelve hours later, she became obtunded and developed subcortical myoclonus. The electroencephalogram demonstrated a diffuse encephalopathy pattern without epileptic activities. She was diagnosed with serotonin syndrome based on Hunter Serotonin Toxicity Criteria. Myoclonus and abnormal vital signs resolved within hours after cyproheptadine administration, but she remained unconscious for 3.5 days. Urine drug screening was positive for benzodiazepines and metabolites, lamotrigine, escitalopram, and hydroxybupropion. This suggested she had overdosed on escitalopram which had been previously prescribed. Unfortunately, vortioxetine and lurasidone could not be detected by our current facilities. CONCLUSION This case exhibited serotonin syndrome and encephalopathy from overdose of multiple psychotropic agents. Her prolonged depressed consciousness could be explained by the half-life of the drugs and possible drug interactions.

Abstract
Lurasidone is an important antipsychotic drug indicated for the treatment of schizophrenia and bipolar disorder, with an oral bioavailability of 9-19% owing to its poor aqueous solubility. Additionally, lurasidone exhibits a 2-fold positive food effect, such that patients must administer their medication with a meal, leading to significant non-compliance. The aim of this research was to evaluate the in vitro and in vivo performance of lurasidone when engineered as nanostructured systems. Specifically, a nanosuspension, nano-emulsion and silica-lipid hybrid (SLH) microparticles were formulated and the influence of composition and nanostructure on the mechanism of solubilisation was compared. Formulations were shown to enhance fasted state solubilisation levels in vitro by up to 5.9-fold, compared to pure drug. Fed- and fasted-state solubilisation profiles revealed that in contrast to the nanosuspension and nano-emulsion, lurasidone SLH mitigated the positive pharmaceutical effect of lurasidone. In vivo pharmacokinetic evaluations revealed that the nanosuspension, nano-emulsion and SLH enhanced the bioavailability of lurasidone by 3-fold, 2.4-fold and 8.8-fold, respectively, compared to pure drug after oral administration. For lurasidone, the combination of lipid-based nanostructure and porous silica nanostructure (SLH) led to optimal fasted state bioavailability which can ultimately result in enhanced treatment efficacy, easier dosing regimens and improved patient outcomes.

Abstract
Lurasidone is a novel azapirone derivative, and atypical antipsychotic agent with a high binding affinity for dopaminergic (D2), serotoninergic (5-HT2A), and 5-HT7 receptors (antagonist), a moderate affinity for 5-HT1A receptors (partial agonist), and no appreciable affinity for histaminergic (H1) and muscarinic (M1) receptors. It was recently included by the European Medication Agency among the in-label pharmacological treatments for children and adolescents affected by early onset schizophrenia. As a dopamine and serotonin antagonist, lurasidone acts on a variety of receptors and showed its efficacy both as an antipsychotic and an activating compound. Administered with food or within 30 minutes from a meal, it presents sufficient bioavailability and does not interact ith most of the other drugs during metabolism. With little effects on hormones and weight gain, potential procognitive profile due to its 5-HT7 antagonism, and reduced extrapyramidal side effects, lurasidone could be a good choice in terms of both effectiveness and tolerability, particularly for patients headed towards a long-term treatment. This article aims to summarize the available scientific evidence from the literature on the use of lurasidone in children and adolescents and to provide recommendations for clinical management and future research.

Abstract
Background The current study evaluated the long-term (52 week) safety and impact on symptom measures of lurasidone (with or without lithium or valproate) for the treatment of bipolar I disorder in Japanese patients. Methods Bipolar patients for this open-label flexibly dosed lurasidone (20–120 mg/day) study were recruited from those with a recent/current depressive episode who completed an initial 6 week, double-blind, placebo-controlled, lurasidone study (depressed group), and those with a recent/current manic, hypomanic, or mixed episode (non-depressed group) who agreed to enroll directly into the long-term study. Measures of adverse events and safety included treatment-emergent adverse events, vital signs, body weight, ECG, laboratory tests, and measures of suicidality and extrapyramidal symptoms. Symptom measures included Montgomery Åsberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS). Results The most common adverse events associated with lurasidone were akathisia (30.7%), nasopharyngitis (26.6%), nausea (12.1%), and somnolence (12.1%). Minimal changes in lipids and measures of glycemic control occurred. Mean change in body weight was + 1.0 kg in the non-depressed group and − 0.8 kg in the depressed group. MADRS total scores declined by a mean (SD) of 2.0 (14.7) points from long-term baseline to endpoint in the depressed group who had received placebo in the prior 6 week trial. The depressed group that had received lurasidone during the prior 6 week study maintained their depressive symptom improvements. For the non-depressed group, YMRS total scores decreased over time. Limitations No control group was included, treatment was open-label, and 49.7% of patients completed the 52 week study. Conclusions Long-term treatment with lurasidone 20–120 mg/day for Japanese patients with bipolar disorder maintained improvements in depressive symptoms for depressed patients who were treated in a prior 6 week trial and led to improvements in manic symptoms among a newly recruited subgroup of patients with a recent/current manic, hypomanic, or mixed episode. Few changes in weight or metabolic parameters were evident. Clinical trial registration: JapicCTI-132319, clinicaltrials.gov—NCT01986114.

Abstract
Non-invasive nose-to-brain delivery presents a competitive strategy for effective drug targeting. This strategy can potentially evade the blood-brain barrier (BBB) depending on the pathway the drug and/or drug/micelle composite travels, thereby allowing direct drug delivery to the brain. This delivery strategy was employed for lurasidone, a clinically USFDA-approved neurotherapeutic molecule in bipolar disorders and schizophrenia treatments. The aim of this study was to develop mixed polymeric micelles of lurasidone HCl (LH) for targeted brain delivery via intranasal route. Lurasidone HCl-loaded mixed micelles (LHMM) were prepared by solvent evaporation method and optimized by 32 factorial design to quantify the effects of excipients on micelle size and entrapment efficiency. Fourier transform infrared spectroscopy helped in scrutinizing drug-excipient interactions whereas transmission electron microscopy images showed particle size and shape. Further, LHMM and LHMM hydrogel were evaluated for in vitro diffusion, histopathology, ex vivo permeation, in vivo pharmacokinetics and stability studies. Optimized LHMM exhibited 175 nm particle size and 97.8% entrapment efficiency with improved in vitro drug diffusion (81%). LHMM hydrogel showed 79% ex vivo drug permeation without any significant signs of nasociliary toxicity to sheep nasal mucosa. Single dose in vivo pharmacokinetic studies showed improved therapeutic concentration of drug in the brain post intranasal administration with 9.5 ± 0.21 μg/mL Cmax and T1/2 of 19.1 ± 0.08 h as compared to pure drug. LHMM, when administered by intranasal route, demonstrated significant increase in the drug targeting efficiency as well as potential (%DTE and %DTP) of drug as compared to pure lurasidone. Thus, nanosized mixed micelles were useful in effective brain delivery of lurasidone HCl via intranasal route. Graphical abstract.

Abstract
BACKGROUND Lurasidone has demonstrated efficacy for short-term treatment of bipolar depression in a diverse ethnic population including Japanese. This study evaluated the long-term safety and effectiveness of open-label lurasidone treatment in these patients. METHODS Patients for this 28-week extension study were recruited from those who completed a 6-week double-blind study of lurasidone, 20-60 mg/day, lurasidone 80-120 mg/day, and placebo. In the extension study, lurasidone was flexibly dosed (20 to 120 mg/day). Safety was evaluated in terms of change from extension-phase baseline to endpoint including adverse events, vital signs, body weight, ECG, laboratory tests, and measures of suicidality and extrapyramidal symptoms. Effectiveness was determined by Montgomery Åsberg Depression Rating Scale (MADRS) and other measures. RESULTS 303 of 413 (73.3%) subjects completed the extension study. Discontinuation due to a treatment-emergent adverse event occurred for 11.4% of those who received placebo, and 8.9% of those who received lurasidone, in the prior 6-week trial. The most common treatment-emergent adverse event was akathisia. Minimal changes were evident on body weight and metabolic parameters. Long-term treatment with lurasidone further reduced mean MADRS total scores from long-term baseline to week 28 (or endpoint) for both those who had received prior placebo (-11.3), and those who had receive prior lurasidone (-8.9), in the 6-week double-blind trial. LIMITATIONS There was no placebo control and treatment was not double-blind. CONCLUSIONS Long-term treatment with lurasidone (20-120 mg/day) was well-tolerated with no new safety concerns and associated with continued improvement in depressive symptoms in this international sample of patients with bipolar depression.

Abstract
BACKGROUND This study examined usefulness and efficiency of Lurasidone in appraisal with the placebo as for the treatment of Bipolar Disorders. METHODS Seven treatment centers in Pakistan were selected for the purpose of starting a six week-long control trial (randomized and double-blind placebo). 76 subjects, already diagnosed with Bipolar I or II based on DSM 5 diagnosis, were selected after randomization. Patients were allocated in one of the two groups. Primary efficacy of the drug was measured using Young Mania Rating Scale. Positive response of the drug was defined as 50% reduction in symptoms from the baseline/13 point less than the baseline score on Young Mania Rating Scale. Efficacy and safety of the drug was assessed using variety of markers such as administering extra-pyramidal symptoms rating scale, adverse side effects reported, electrocardiograms, body weight, vital signs changes, and laboratory investigations. RESULTS Patients treated with Lurasidone showed enhanced improvement in their overall health and symptoms manifestation in comparison to patients who were given placebo. Lurasidone treated patients showed a better response to the drug (66%), in comparison with the placebo treated patients (42%). LIMITATIONS Study was conducted on small scale due to complexity. CONCLUSION Patients treated with Lurasidone showed reduction in bipolar symptoms and tolerate the drug well.

Abstract
Antipsychotics are often used in combination with other psychotropic drugs to treat a variety of psychiatric disorders, as well as in combination with other drugs taken by patients with co-morbidities. When these drugs are combined, the potential for drug-drug interaction increases, leading to side-effects, in addition to the predicted increase in effectiveness. The present study aimed at examining the effects of the three atypical neuroleptics asenapine, lurasidone and iloperidone on cytochrome P450 (CYP) expression in the human liver. The study was carried out on cryopreserved human hepatocytes. The hepatotoxicity of the tested drugs was assessed after exposure to the neuroleptics (LDH cytotoxicity assay). CYP activities were measured in the incubation medium using the CYP-specific reactions: caffeine 3-N-demethylation (CYP1A1/2), diclofenac 4'-hydroxylation (CYP2C9), perazine N-demethylation (CYP2C19) and testosterone 6β-hydroxylation (CYP3A4). Parallel, CYP mRNA levels were measured in neuroleptic-treated hepatocytes. Asenapine significantly decreased the mRNA level and activity of CYP1A2, while iloperidone potently diminished the mRNA level and activity of CYP3A4 in the cultures of human hepatocytes. Lurasidone did not affect the expression and activity of any of the investigated human CYP enzymes. The presented findings may have clinical implications for the prediction of potential drug-drug interactions involving the asenapine-induced inhibition of metabolism of CYP1A2 substrates (e.g. caffeine, theophylline, melatonin, tricyclic antidepressants, phenacetin, propranolol) and iloperidone-induced inhibition of CYP3A4 substrates (e.g. antidepressants, benzodiazepines, atorvastatin, macrolide antibiotics, calcium channel antagonists).

Abstract
OBJECTIVE Patients with schizophrenia are at higher risk of cardiovascular morbidity and mortality than healthy individuals. This study was conducted to compare the effect of lurasidone and olanzapine on cardiometabolic parameters in unmedicated patients with schizophrenia. METHODS The present study was a randomized open-label, parallel design, active-controlled clinical trial. After recruitment and randomization of 101 patients, a baseline assessment was done by PANSS, SOFAS, lipid profile, fasting blood glucose, HbA1c, serum insulin and serum hs-CRP. HOMA-IR, atherogenic index, coronary risk index and cardiovascular risk indices were calculated as derived parameters. Patients received either lurasidone 80 mg or olanzapine 10 mg as monotherapy and followed up after 6 weeks. RESULTS There was a significant increase in fasting blood glucose (p < 0.001), HbA1c (p < 0.001) and serum insulin (p < 0.001) after 6 weeks of therapy in both the treatment groups but the difference between the groups was not significant (FBS, p = 0.209; HbA1c, p = 0.209; serum insulin, p = 0.720). Olanzapine showed worsening of lipid profile (p < 0.001) while the same improved with lurasidone (p < 0.001) and the difference between the groups was found to be significant (p < 0.001). Serum HDL level decreased in both the treatment groups (olanzapine, p < 0.001; lurasidone, p < 0.001) but the difference between the groups was not significant (p = 0.333). There was an increase in hs-CRP levels in both the treatment groups (olanzapine, p < 0.001; lurasidone, p < 0.001) with no significant difference between them (p = 0.467). Atherogenic index, coronary risk index and cardiovascular risk index increased significantly in the olanzapine group as compared with the lurasidone group (p < 0.001). CONCLUSION Lurasidone showed a favourable effect on lipid profile and cardiovascular risk indices over olanzapine. However, long-term studies are needed to establish and generalize the findings.

Abstract
Introduction A post hoc analysis of a double-blind (DB) active control trial and an open-label extension (OLE) study was conducted to evaluate the long-term effects of lurasidone in patients with schizophrenia. Methods In the DB trial, patients were randomised to receive lurasidone or risperidone for 12 months. In OLE, all patients received lurasidone for an additional 6 months. Treatment-emergent adverse events (TEAEs) were evaluated. Efficacy assessments included relapse rate (DB trial only), and Positive and Negative Syndrome Scale, Clinical Global Impression–Severity scale, and Montgomery–Åsberg Depression Rating Scale. Results In the DB trial, patients with schizophrenia were randomised to lurasidone (n = 399) and risperidone (n = 190), of whom 129 and 84 continued into OLE, respectively. During the DB trial, incidence of TEAEs was similar for lurasidone (84.1%) and risperidone (84.2%). Lurasidone was associated with minimal changes in metabolic variables and prolactin levels, whereas risperidone was associated with clinically significant increases in prolactin and fasting glucose levels. The proportion of patients with metabolic syndrome was significantly lower in patients treated with lurasidone versus risperidone at the end of the DB trial (25.5% vs 40.4%; p = 0.0177). During OLE, patients switching from risperidone to lurasidone experienced a reduction in weight and prolactin levels; those continuing treatment with lurasidone experienced minimal changes in metabolic variables and prolactin. At the end of OLE, the proportion of patients with metabolic syndrome was no longer significantly different between groups (23.5% vs 31.5%; p = not significant). Efficacy outcomes were generally similar between groups during the DB trial, and were maintained during OLE. Conclusion Lurasidone was generally well tolerated and effective in clinically stable schizophrenia patients over the long term. Lurasidone was also generally well tolerated and maintained effectiveness over 6 months in patients switching from risperidone. Patients switching from risperidone experienced improvements in metabolic parameters and prolactin levels. These findings confirm lurasidone’s long-term effectiveness and favourable metabolic profile in patients with schizophrenia. Trial Registration ClinicalTrials.gov identifier NCT00641745.

Abstract
BACKGROUND Patients with a diagnosis of schizophrenia are at an increased risk for developing metabolic syndrome, which is associated with greater cardiovascular morbidity and mortality. Treatment with some commonly used antipsychotic medications may increase the risk of developing metabolic syndrome. The aim of the study was to evaluate the safety of lurasidone in patients who continued lurasidone or switched from risperidone to lurasidone. A secondary aim was assessment of the effect of long-term lurasidone on the Positive and Negative Syndrome Scale (PANSS). METHODS The treatment sample in the current study consisted of clinically stable patients with schizophrenia (N = 223) who had completed a 12-month, double-blind study of lurasidone vs. risperidone. In the current extension study, all patients received 6 months of open-label treatment with lurasidone, either continuing lurasidone assigned during the preceding double-blind trial, or switching from double-blind risperidone to lurasidone. Safety and tolerability parameters included body weight, prolactin, and metabolic laboratory tests. RESULTS Six months of OL treatment with lurasidone was generally well-tolerated, with a low incidence of parkinsonism (4.5%) and akathisia (3.1%). Overall, few adverse events were rated as severe (4.9%), and discontinuation due to an adverse event was low in the lurasidone continuation vs. risperidone switch groups (3.7% vs. 6.9%). In the lurasidone continuation versus risperidone switch groups, change from OL baseline to 6-month endpoint (observed case) was observed in mean body weight (- 0.6 vs. -2.6 kg), median total cholesterol (- 4.0 vs. + 4.5 mg/dL), triglycerides (- 4.5 vs. -5.5 mg/dL), glucose (0.0 vs. -3.0 mg/dL) and prolactin (males, + 0.15 vs. -11.2 ng/mL; females, + 1.3 vs. -30.8 ng/mL). Improvement in PANSS total score was maintained, from OL baseline to endpoint in the continuation vs. switch groups (+ 1.0 vs. -1.0; OC). CONCLUSIONS In this 6-month extension study, lurasidone treatment was generally well-tolerated and associated with minimal effects on weight, metabolic parameters, and prolactin levels. Patients who switched from risperidone to lurasidone experienced reductions in weight, metabolic parameters and prolactin levels commensurate with increases in these safety parameters experienced during the previous 12 months of treatment with risperidone.

Abstract
Background The present study aimed at examining the inhibitory effect of two atypical neuroleptics iloperidone and lurasidone on the main human cytochrome P450 (CYP) enzymes in pooled human liver microsomes and cDNA-expressed CYP enzymes (supersomes). Methods The activity of these enzymes was determined by the following CYP-specific reactions: caffeine 3-N-demethylation/CYP1A2, diclofenac 4′-hydroxylation/CYP2C9, perazine N-demethylation/CYP2C19, bufuralol 1′-hydroxylation/CYP2D6 and testosterone 6β-hydroxylation/CYP3A4, respectively, using HPLC. Results Iloperidone inhibited the activity of CYP3A4 via a noncompetitive mechanism (Ki = 0.38 and 0.3 µM in liver microsomes and supersomes, respectively) and CYP2D6 via a competitive mechanism (Ki = 2.9 and 10 µM in microsomes and supersomes). Moreover, iloperidone attenuated the activity of CYP1A2 (Ki = 45 and 31 µM in microsomes and supersomes) and CYP2C19 via a mixed mechanism (Ki = 6.5 and 32 µM in microsomes and supersomes) but did not affect CYP2C9. Lurasidone moderately inhibited CYP1A2 (Ki = 12.6 and 15.5 µM in microsomes and supersomes), CYP2C9 (Ki = 18 and 3.5 µM in microsomes and supersomes) and CYP2C19 via a mixed mechanism (Ki = 18 and 18.4 µM in microsomes and supersomes), and CYP3A4 via a competitive mechanism (Ki = 29.4 and 9.1 µM in microsomes and supersomes). Moreover, lurasidone competitively, though weakly diminished the CYP2D6 activity (Ki = 37.5 and 85 µM in microsomes and supersomes). Conclusion The examined neuroleptics showed inhibitory effects on different CYP enzymes. The obtained results indicate that metabolic/pharmacokinetic interactions with iloperidone (involving mainly CYP3A4 and CYP2D6) and possibly with lurasidone (involving CYP1A2, CYP2C9 or CYP2C19) may occur during combined therapy.

Abstract
Lurasidone was approved by the United States Food and Drug Administration (FDA) for the treatment of schizophrenia, as well as for the treatment of bipolar depression. However, emerging reports have indicated various adverse drug reactions with the use of lurasidone. Thus, in this article, we have analyzed the risk profile of lurasidone in the established therapeutic indication. A total of 419 studies were published from October 2010-July 2019 regarding lurasidone. After the inclusion and exclusion criteria, 17 studies were selected for the analysis of risk. The adverse drug reactions (ADRs) of these studies were categorized as per the innovator summary of product characteristics (SmPC). Finally, the unlisted ADRs were analyzed by using the Naranjo probability algorithm. Telogen effluvium, thrombocytopenia, restless leg syndrome and hypersexuality were found with the use of lurasidone and fall under the unlisted category. The causality assessment has shown a probable correlation of lurasidone with hypersexuality, restless leg syndrome, thrombocytopenia and possible relation with telogen effluvium. In conclusion, lurasidone is a novel and efficacious pharmacological treatment for bipolar depression and schizophrenia. However, more data regarding the safety of this drug in a large population is needed.

Abstract
This network meta-analysis assessed the efficacy and tolerability of lurasidone versus other oral atypical antipsychotic monotherapies in adolescent schizophrenia. A systematic literature review identified 13 randomized controlled trials of antipsychotics in adolescents with schizophrenia-spectrum disorders. A Bayesian network meta-analysis compared lurasidone to aripiprazole, asenapine, clozapine, olanzapine, paliperidone extended-release (ER), quetiapine, risperidone, and ziprasidone. Outcomes included Positive and Negative Syndrome Scale (PANSS), Clinical Global Impressions-Severity (CGI-S), weight gain, all-cause discontinuation, extrapyramidal symptoms (EPS), and akathisia. Results were reported as median differences for continuous outcomes and odds ratios (ORs) for binary outcomes, along with 95% credible intervals (95% CrI). Lurasidone was significantly more efficacious than placebo on the PANSS (- 7.95, 95% CrI - 11.76 to - 4.16) and CGI-S (- 0.44, 95% CrI - 0.67 to - 0.22) scores. Lurasidone was associated with similar weight gain to placebo and statistically significantly less weight gain versus olanzapine (- 3.62 kg, 95% CrI - 4.84 kg to - 2.41 kg), quetiapine (- 2.13 kg, 95% CrI - 3.20 kg to - 1.08 kg), risperidone (- 1.16 kg, 95% CrI - 2.14 kg to - 0.17 kg), asenapine (- 0.98 kg, 95% CrI - 1.71 kg to - 0.24 kg), and paliperidone ER (- 0.85 kg, 95% CrI - 1.57 kg to - 0.14 kg). The odds of all-cause discontinuation were significantly lower for lurasidone than aripiprazole (OR = 0.28, 95% CrI 0.10-0.76) and paliperidone ER (OR = 0.25, 95% CrI 0.08-0.81) and comparable to other antipsychotics. Rates of EPS and akathisia were similar for lurasidone and other atypical antipsychotics. In this network meta-analysis of atypical antipsychotics in adolescent schizophrenia, lurasidone was associated with similar efficacy, less weight gain, and lower risk of all-cause discontinuation compared to other oral atypical antipsychotics.

Abstract
Lurasidone is an atypical mood-stabilizing antipsychotic agent with unique receptor-binding profile, including 5-HT7 receptor (5-HT7R) antagonism. Effects of 5-HT7R antagonism on transmitter systems of schizophrenia and mood disorders, however, have not been well clarified. Thus, this study examined the mechanisms underlying the clinical effects of lurasidone by measuring mesocortical serotonergic transmission. Following systemic and local administrations of lurasidone, MK801 and 5-HT receptor modulators, we determined releases of 5-HT in dorsal raphe nucleus (DRN), mediodorsal thalamic nucleus (MDTN) and medial prefrontal cortex (mPFC) and γ-aminobutyric acid (GABA) in DRN using multiprobe microdialysis with ultra-high-performance liquid chromatography (UHPLC). Serotonergic and GABAergic neurons in the DRN are predominantly regulated by inhibitory 5-HT1A receptor (5-HT1AR) and excitatory 5-HT7R, respectively. Lurasidone acutely generates GABAergic disinhibition by 5-HT7R antagonism, but concomitant its 5-HT1AR agonism prevents serotonergic hyperactivation induced by 5-HT7R inhibition. During treatments with 5-HT1AR antagonist in DRN, lurasidone dose-dependently increased 5-HT release in the DRN, MDTN and mPFC. Contrary, lurasidone chronically enhanced serotonergic transmission and GABAergic disinhibition in the DRN by desensitizing both 5-HT1AR and 5-HT7R. These effects of lurasidone acutely prevented MK801-evoked 5-HT release by GABAergic disinhibition via N-methyl-D-aspartate (NMDA)/glutamate receptor (NMDA-R)-mediated inhibition of 5-HT1AR function, but enhanced MK801-induced 5-HT release by desensitizing 5-HT1AR and 5-HT7R. These results indicate that acutely lurasidone fails to affect 5-HT release, but chronically enhances serotonergic transmission by desensitizing both 5-HT1AR and 5-HT7R. These unique properties of lurasidone ameliorate the dysfunctions of NMDA-R and augment antidepressive effects.

Abstract
Second generation antipsychotics (SGAs) are effective options in the treatment of schizophrenia and mood disorders, each with characteristic efficacy and safety features. In order to optimize the balance between efficacy and side effects, it is of upmost importance to match compound specificity against patient clinical profile. As the number of SGAs increased, this review can assist physicians in the prescription of three novel SGAs already on the market, namely lurasidone, brexpiprazole, cariprazine, and lumateperone, which is in the approval phase for schizophrenia treatment at the FDA. Besides schizophrenia, EMA and/or FDA approved lurasidone for bipolar depression, brexpiprazole as augmentation in major depressive disorder and cariprazine for the acute treatment of manic or mixed episodes associated with bipolar I disorder. These new antipsychotics were developed with the aim of improving efficacy on negative and depressive symptoms and reducing metabolic and cardiovascular side effects compared to prior SGAs, while keeping the risk of extrapyramidal symptoms low. They succeeded quite well in containing these side effects, despite weight gain during acute treatment remains a possible concern for brexpiprazole, while cariprazine and lurasidone show higher risk of akathisia compared to placebo and other SGAs such as olanzapine. The available studies support the expected benefits on negative symptoms, cognitive dysfunction and depressive symptoms, while the overall effect on acute psychotic symptoms may be similar to other SGAs such as quetiapine, aripiprazole and ziprasidone. The discussed new antipsychotics represent useful therapeutic options but their efficacy and side effect profiles should be considered to personalize prescription.

Abstract
Introduction Lurasidone is an atypical antipsychotic that was approved in Europe in 2014 for the treatment of schizophrenia in adults aged ≥ 18 years. Clinical experience with lurasidone in Europe is currently limited, and there is therefore a need to provide practical guidance on using lurasidone for the treatment of adults with schizophrenia. Methods A panel of European psychiatrists with extensive experience of prescribing lurasidone was convened to provide recommendations on using lurasidone to treat adults with schizophrenia. Results Extensive evidence from clinical trials and the panel’s clinical experience suggest that lurasidone is as effective as other atypical agents, with the possible exception of clozapine. Lurasidone is associated with a lower propensity for metabolic side effects (in particular, weight gain) and hyperprolactinaemia than most other atypical antipsychotics and has a relatively benign neurocognitive side effect profile. Patients switching to lurasidone from another antipsychotic may experience weight reduction and/or improvements in the ability to focus/concentrate. Most side effects with lurasidone (such as somnolence) are transitory, easily managed and/or ameliorated by dose adjustment. Akathisia and extrapyramidal symptoms may occur in a minority of patients, but these can be managed effectively with dose adjustment, adjunctive therapy and/or psychosocial intervention.

Abstract
Neurotrophic factors like Brain-Derived Neurotrophic Factor (BDNF), Neurotrophin 3 (NT3) and Nerve Growth Factor (NGF), play a role in neuroplasticity and neurogenesis contributing to the pathogenesis of schizophrenia. The objective of the present study was to investigate and compare the effect of olanzapine and lurasidone on the change in serum neurotrophins in patients with schizophrenia. The present study was a randomized, open-label, active-controlled, parallel design clinical trial. After randomization baseline evaluations of serum BDNF, NGF, NT3, Positive and Negative Syndrome Scale (PANSS) scoring, Social and Occupational Functioning Assessment Scale (SOFAS) scoring of 101 unmedicated schizophrenia patients were done. Patients were reassessed after 6 weeks of monotherapy with olanzapine or lurasidone. Serum BDNF increased after treatment with both the drug groups but rise with olanzapine was found to be significantly higher (916.22; 95 %CI: 866.07 to 966.37; p < 0.001) in comparison to lurasidone. Increase in levels NGF and NT3 was also observed but there was no significant difference between the groups (NGF: 2.32; CI: 3.54 to -3.53; p = 0.57 and NT3: 0.99; CI: 2.11 to 0.14; p = 0.086). The difference in improvement in PANSS and SOFASS with both the drugs was not statistically significant. Both the drugs alleviate the symptoms of schizophrenia but olanzapine was better tolerated. Our findings suggest that increase in serum BDNF with olanzapine monotherapy is significantly higher than that with lurasidone but there is no significant difference in change in serum NGF and NT3. TRIAL REGISTRATION: ClinicalTrials.gov identifier: (NCT03304457).

Abstract
OBJECTIVES To assess the efficacy and tolerability of lurasidone versus other atypical antipsychotic monotherapy agents in patients with bipolar depression, using a Bayesian network meta-analysis. METHODS Fourteen randomised clinical trials (6221 patients) of lurasidone, quetiapine (extended release and immediate release), aripiprazole, olanzapine, and ziprasidone for bipolar depression were included. Efficacy assessments included change in the Montgomery-Åsberg Depression Rating Scale (MADRS), rates of response (≥50% improvement in MADRS) and remission (MADRS ≤12 at study endpoint), and change in the Clinical Global Impressions-Bipolar Disorder-Severity (CGI-BP-S) scale. Tolerability outcomes included weight, somnolence, extrapyramidal symptoms (EPS), and all-cause discontinuation. Changes from baseline or odds ratios (OR) with 95% credible intervals (CrI) were evaluated. RESULTS Improvement in the MADRS associated with lurasidone treatment was significantly greater than placebo (-4.70, 95%CrI: -7.20, -2.21), aripiprazole (-3.62, 95%CrI: -7.04, -0.20), and ziprasidone (-3.38, 95%CrI: -6.68, -0.11), but not olanzapine (-0.15, 95%CrI: -3.12, 2.74) or quetiapine (0.10, 95%CrI: -2.68, 2.84). Results for improvement in the CGI-BP-S, and for response and remission were similar. Lurasidone was associated with less weight gain than olanzapine (-2.54 kg, 95%CrI: -3.42, -1.67) and quetiapine (-0.83kg, 95%CrI: -1.59, -0.08); and with lower rates of somnolence than quetiapine (OR: 0.33, 95%CrI: 0.11, 0.82) and ziprasidone (OR: 0.34, 95%CrI: 0.09, 0.93). No significant differences among atypical antipsychotic agents were observed in rates of discontinuation or in rates of EPS. CONCLUSIONS In this network meta-analysis, lurasidone was found to be more efficacious than aripiprazole and ziprasidone, and was associated with less weight gain than quetiapine and olanzapine and less somnolence than quetiapine and ziprasidone.

Abstract
RATIONALE The effect of atypical antipsychotic drugs (AAPDs), e.g., lurasidone, to improve cognitive impairment associated with schizophrenia (CIAS), has been suggested to be due, in part, to enhancing release of dopamine (DA), acetylcholine (ACh), and glutamate (Glu) in cortex and hippocampus. RESULTS The present study found acute lurasidone reversed the cognitive deficit in novel object recognition (NOR) in subchronic (sc) phencyclidine (PCP)-treated mice, an animal model for CIAS. This effect of lurasidone was blocked by pretreatment with the 5-HT1AR antagonist, WAY-100635, or the 5-HT7R agonist, AS 19. Lurasidone significantly increased medial prefrontal cortex (mPFC) ACh, DA, and Glu efflux, all of which were blocked by WAY-100635, with similar effects in the dorsal striatum (dSTR), except for the absence of an effect on Glu increase. AS 19 inhibited Glu, but not DA efflux, in the dSTR. The selective 5-HT7R antagonist, SB-26970, increased mPFC DA, 5-HT, Glu, and, importantly, also GABA efflux and striatal DA, NE, 5-HT, and Glu efflux, indicating tonic inhibition of the release of these neurotransmitters by 5-HT7R stimulation. These results provide new evidence that GABA release in the mPFC is tonically inhibited by 5-HT7R stimulation and suggest that a selective 5-HT7R antagonist might be clinically useful to enhance cortical GABAergic release. All SB-269970 effects were blocked by AS 19 or WAY-100635, suggesting 5-HT1AR agonism is necessary for the release of these neurotransmitters by SB-269970. Lurasidone increased ACh, DA, and NE but not Glu efflux in mPFC and dSTR DA and Glu efflux in 5-HT7 KO mice. CONCLUSION We conclude that lurasidone-induced Glu efflux in mPFC requires 5-HT7R antagonism while its effects on cortical ACh and DA efflux are mainly due to 5-HT1AR stimulation.

Abstract
Prior studies suggest that the inflammatory biomarker c-reactive protein (CRP) holds promise for predicting antidepressant response in patients with major depressive disorder. The objective of this study was to evaluate whether CRP might similarly predict antidepressant responses to lurasidone in patients with bipolar I depression. Serum CRP concentration was measured prior to, and following, 6 weeks of treatment in 485 outpatients with bipolar I depression. Patients were randomized to receive monotherapy with lurasidone 20-60 mg/day (N = 161), lurasidone 80-120 mg/day (N = 162) or placebo (N = 162). CRP was assessed using the wide-range CRP assay (wr-CRP). The primary efficacy endpoint was change from baseline to week 6 in Montgomery-Åsberg Depression Rating Scale (MADRS) score. Mixed models and statistical interaction tests were applied to investigate the moderating effects of pre-treatment wr-CRP on clinical endpoints. CRP was evaluated as a log-transformed continuous variable and by clinically-relevant cut-points. Increasing pre-treatment wr-CRP level predicted a larger overall antidepressant response to lurasidone, as well as an increased response for a number of individual depressive symptoms. These moderating effects of pre-treatment wr-CRP remained significant after adjustment for potential confounds (e.g. baseline BMI and weight change). Treatment with lurasidone did not affect serum concentrations of CRP compared to placebo during the study. Elevated CRP level prior to treatment was associated with an enhanced clinical response to lurasidone in patients with bipolar I depression. If confirmed in future studies, CRP may represent a clinically useful diagnostic and predictive biomarker supporting a precision medicine approach to the treatment of bipolar depression.

Abstract
A genome-wide association study (GWAS) of response of schizophrenia patients to the atypical antipsychotic drug, lurasidone, based on two double-blind registration trials, identified SNPs from four classes of genes as predictors of efficacy, but none were genome wide significant (GWS). After inclusion of data from a third lurasidone trial, meta-analysis identified a GWS marker and other findings consistent with our first study. The primary end-point was change in Total Positive and Negative Syndrome Scale (PANSS) between baseline and last observation carried forward. rs4736253, a genetic locus near KCNK9, encoding the K2P9.1 potassium channel, with a role in cognition and neurodevelopment, was the top marker in patients of European ancestry (EUR) (n = 264), reaching GWS (p = 4.78 × 10-8). rs10180106 (p = 4.92 × 10-7), located at an intron region of CTNNA2, a SCZ risk gene important for dendritic spine stabilization, was one of other best response markers for EUR patients. SNPs at STXBP5L (rs511841, p = 2.63 × 10-7) were the top markers for patients of African ancestry (n = 158). The association between PTPRD, NRG1, and MAGI1 previously reported to be related to response to lurasidone in the first two trials, showed a trend of significant association in the third trial. None of these genetic loci showed significant associations with clinical response in the corresponding placebo groups (n = 107 for EUR; n = 58 for AFR). This meta-analysis yielded the first GWAS-based GWS biomarker for lurasidone response and additional support for the conclusion that genes related to synaptic biology and/or risk for SCZ are the strongest predictors of response to lurasidone in schizophrenia patients.

Abstract
Depression is the predominant pole of disability in bipolar disorder and compared with mania/hypomania, has less systematic research guiding the development of treatment especially in its acute phase (acute bipolar depression). The deficiency in the management of the acute bipolar depression largely reflects the natural divergence of opinion resulting from significant knowledge gaps. At present, there are only 3 approved drug treatments for acute bipolar depression: olanzapine/fluoxetine combination, quetiapine (immediate or extended release), and lurasidone (monotherapy or adjunctive to lithium or valproate). Nonapproved agents and nonpharmacologic treatment such as lamotrigine, antidepressants, modafinil, pramipexole, ketamine, and electroconvulsive therapy are often prescribed to treat acute bipolar depression. This article discusses the challenges of diagnosing bipolar depression, and reviews above treatment options for acute bipolar depression.

Abstract
BACKGROUND Lurasidone, an azapirone derivative, is a novel second generation antipsychotic with potent binding affinity for dopamine D2, serotonin 5-HT2A, 5-HT7, 5-HT1A, and noradrenaline alpha2C receptors. This updated meta-analysis of randomized controlled trials (RCTs) examined the short-term efficacy and tolerability of lurasidone in the treatment of acute schizophrenia. METHODS Double-blinded RCTs reporting on the short-term effects of lurasidone were included. Standardized mean difference (SMD) with their 95% confidence interval (CI), and number needed to harm (NNH) were computed. RESULTS The meta-analysis had 8 RCTs with 16 active arms that included 2373 patients with acute schizophrenia who were randomized to either lurasidone (20-160 mg/day; n = 1570) or placebo (n = 803) groups. Lurasidone was superior to placebo with regard to change in total psychopathology [SMD: -0.34, (95%CI: -0.48, -0.20), P<0.00001], positive symptoms [SMD: -0.47, (95%CI: -0.57, -0.36), P<0.00001], negative symptoms [SMD:-0.34, (95%CI: -0.45, -0.22), P<0.00001], and general psychopathology [SMD: -0.36, (95%CI: -0.48, -0.24), P<0.00001]. Results were consistent for total psychopathology in 11 out of the 13 subgroups. Lurasidone resulted in higher weight gain [SMD: 0.15, (95% CI: 0.06, 0.24), P = 0.001] and BMI [SMD: 0.17, (95%CI: 0.07, 0.28), P = 0.002] than placebo, but the differences were not clinically significant. Lurasidone group had less frequent inefficacy (NNH = 14) and discontinuation due to any reason (NNH = 17), but was associated with more frequent vomiting, akathisia, dystonia, parkinsonism, somnolence, dizziness, sedation, nausea, and weight gain of ≥7% of the initial weight (NNH = 11-50). CONCLUSION This meta-analysis of 8 short-term studies supported the efficacy and safety of lurasidone in the acute phase of schizophrenia, particularly at the higher dose range of 80 mg/day.

Abstract
BACKGROUND Pregnenolone sulfate (PregS), an endogenous neurosteroid, which negatively and positively modulates gamma amino butyric acid subunit A (GABAA) and N-methyl D-aspartate (NMDA) receptors (R) respectively, among other potential neuroplastic changes on synaptic processes, has shown some beneficial effects on treating cognitive impairment associated with schizophrenia (CIAS) and negative symptoms. Lurasidone (Lur), an atypical antipsychotic drug (AAPD), and tandospirone (Tan), a 5-HT1A R partial agonist, have also been reported to improve cognitive or negative symptoms, or both, in some schizophrenia patients. METHODS We tested whether PregS, by itself, and in combination with Lur or Tan could rescue persistent deficits produced by subchronic treatment with the NMDAR antagonist, phencyclidine (PCP)-in episodic memory, executive functioning, and social behavior, using novel object recognition (NOR), operant reversal learning (ORL), and social interaction (SI) tasks, in male C57BL/6 J mice. RESULTS PregS (10, but not 3 mg/kg) significantly rescued subchronic PCP-induced NOR and SI deficits. Co-administration of sub-effective doses (SEDs) of PregS (3 mg/kg) + Lur (0.1 mg/kg) or Tan (0.03 mg/kg) rescued scPCP-induced NOR and SI deficits. Further, PregS (30, but not 10 mg/kg) rescued PCP-induced ORL deficit, as did the combination of SED PregS (10 mg/kg) +SED Lur (1 mg/kg) or Tan (1 mg/kg). CONCLUSION PregS was effective alone and as adjunctive treatment for treating two types of cognitive impairments and negative symptoms in this schizophrenia model. Further study of the mechanisms by which PregS alone and in combination with AAPDs and 5-HT1A R partial agonists, rescues the deficits in cognition and SI in this preclinical model is indicated.

Abstract
Biomarkers which predict response to atypical antipsychotic drugs (AAPDs) increases their benefit/risk ratio. We sought to identify common variants in genes which predict response to lurasidone, an AAPD, by associating genome-wide association study (GWAS) data and changes (Δ) in Positive And Negative Syndrome Scale (PANSS) scores from two 6-week randomized, placebo-controlled trials of lurasidone in schizophrenia (SCZ) patients. We also included SCZ risk SNPs identified by the Psychiatric Genomics Consortium using a polygenic risk analysis. The top genomic loci, with uncorrected p<10-4, include: 1) synaptic adhesion (PTPRD, LRRC4C, NRXN1, ILIRAPL1, SLITRK1) and scaffolding (MAGI1, MAGI2, NBEA) genes, both essential for synaptic function; 2) other synaptic plasticity-related genes (NRG1/3 and KALRN); 3) the neuron-specific RNA splicing regulator, RBFOX1; and 4) ion channel genes, e.g. KCNA10, KCNAB1, KCNK9 and CACNA2D3). Some genes predicted response for patients with both European and African Ancestries. We replicated some SNPs reported to predict response to other atypical APDs in other GWAS. Although none of the biomarkers reached genome-wide significance, many of the genes and associated pathways have previously been linked to SCZ. Two polygenic modeling approaches, GCTA-GREML and PLINK-Polygenic Risk Score, demonstrated that some risk genes related to neurodevelopment, synaptic biology, immune response, and histones, also contributed to prediction of response. The top hits predicting response to lurasidone did not predict improvement with placebo. This is the first evidence from clinical trials that SCZ risk SNPs are related to clinical response to an AAPD. These results need to be replicated in an independent sample.

Abstract
BACKGROUND Severe and persistent mental illnesses, such as schizophrenia and bipolar disorder, are associated with increased risk of obesity compared to the general population. While the association of lurasidone and lower risk of weight gain has been established in short and longer-term clinical trial settings, information about lurasidone's association with weight gain in usual clinical care is limited. This analysis of usual clinical care evaluated weight changes associated with lurasidone treatment in patients with schizophrenia or bipolar disorder. METHODS A retrospective, longitudinal analysis was conducted using de-identified electronic health records from the Humedica database for patients who initiated lurasidone monotherapy between February 2011 and November 2013. Weight data were analyzed using longitudinal mixed-effects models to estimate the impact of lurasidone on patient weight trajectories over time. Patients' weight data (kg) were tracked for 12-months prior to and up to 12-months following lurasidone initiation. Stratified analyses were conducted based on prior use of second-generation antipsychotics with medium/high risk (clozapine, olanzapine, quetiapine, or risperidone) versus low risk (aripiprazole, ziprasidone, first-generation antipsychotics, or no prior antipsychotics) for weight gain. RESULTS Among the 439 included patients, the mean age was 42.2 years, and 69.7% were female. The average duration of lurasidone treatment across all patients was 55.2 days and follow-up duration after the index date was 225.1 days. The estimated impact of lurasidone on weight was - 0.77 kg at the end of the 1-year follow-up. Patients who had received a prior second-generation antipsychotic with medium/high risk for weight gain were estimated to lose an average of 1.68 kg at the end of the 1-year follow-up. CONCLUSIONS Lurasidone was associated with a reduction in weight at 1 year following its initiation in patients with schizophrenia or bipolar disorder. Stratified analyses indicated that weight reduction was more pronounced among patients who had received second-generation antipsychotics associated with a higher risk of weight gain prior to lurasidone treatment. These findings are consistent with the results of prior short- and long-term prospective studies and suggest that lurasidone is associated with low risk for weight gain in patients with schizophrenia or bipolar disorder.

Abstract
Lurasidone (DS-RAn) has demonstrated efficacy in the acute treatment of bipolar depression, both as monotherapy, and as combination therapy with lithium or valproate. To evaluate the recurrence prevention efficacy of lurasidone for the maintenance treatment of bipolar I disorder, patients received up to 20 weeks of open-label lurasidone (20-80mg/d) combined with lithium or valproate during an initial stabilization phase. A total of 496 patients met stabilization criteria and were randomized to 28 weeks of double-blind treatment with lurasidone (20-80mg/d) or placebo, in combination with lithium or valproate. Based on a Cox proportional hazard model, treatment with lurasidone reduced the probability of recurrence of any mood episode by 29% (primary endpoint), however, the reduction did not achieve statistical significance. Probability of recurrence on lurasidone was significantly lower in patients with an index episode of depression (HR, 0.57; P=0.039), in patients with any index episode who were not rapid-cycling (HR, 0.69; P=0.046), and when recurrence was based on MADRS, YMRS, or CGI-BP-S severity criteria (HR, 0.53; P=0.025; sensitivity analysis). Long-term treatment with lurasidone combined with lithium or valproate was found to be safe and well-tolerated, with minimal effects on weight or metabolic parameters.

Abstract
BACKGROUND Several studies have found that depressed, post-menopausal females may respond differently to antidepressants compared to pre-menopausal females. The atypical antipsychotic lurasidone, whose mechanism of action differs from SSRIs and other standard antidepressants, was shown in a 6-week randomized, flexible-dose, placebo-controlled study (n=209), to be effective in treating major depressive disorder (MDD) with mixed features (subthreshold hypomanic symptoms). This post-hoc analysis assessed the efficacy of lurasidone in this study by menopausal status. METHODS The main outcome measure for this post-hoc analysis was change in MADRS score from baseline to week 6 endpoint for two lurasidone-treated subgroups: presumptive pre-menopausal (<52years) and presumptive post-menopausal (≥52years) patients, compared to placebo treatment, using a mixed-model for repeated-measures analysis, and calculation of the effect size for each subgroup. Additional efficacy assessments included the CGI-S, HAM-A and YMRS. An exploratory analysis was also conducted removing presumptive peri-menopausal women (ages 45-51years) to allow for clearer definition of pre- and post-menopausal status. RESULTS A total of 56 lurasidone-treated and 47 placebo-treated pre-menopausal females, and 17 lurasidone-treated and 25 placebo-treated post-menopausal females were available from the larger study for comparison on key outcome measures. The pre- and post-menopausal subgroups had similar demographic and clinical characteristics at study baseline (other than age), including number of past major depressive episodes as well as depressive and manic symptom severity. Mean daily lurasidone dose was similar for each subgroup during the study. Both the primary and exploratory analyses showed that both lurasidone-treated post-menopausal and pre-menopausal females responded significantly compared to placebo (p=0.016 or less) on the MADRS, and that post-menopausal patients had a numerically larger response (effect size=0.96) than pre-menopausal patients (effect size=0.64). All other secondary outcome measures for lurasidone compared with placebo treatment were significant (p=0.045 or less) for both subgroups. CONCLUSIONS In this post-hoc analysis, lurasidone was found to be effective in treating post-menopausal MDD patients with mixed features (subthreshold hypomanic symptoms).

Abstract
Daytime sleepiness is a commonly reported adverse effect associated with psychotropic agents that may impair cognitive performance and functioning. The objective of this post-hoc analysis was to evaluate the long-term effects of lurasidone and quetiapine XR on daytime sleepiness and neurocognitive performance during a 6-month, double-blind continuation study, in subjects who completed an initial 6-week, randomized, placebo-controlled trial comparing these agents. Daytime sleepiness, cognitive performance, and health-related quality of life were assessed with the Epworth Sleepiness Scale (ESS), CogState computerized battery, and the Quality of Well-Being (QWB-SA) Scale, respectively. Treatment with flexible-dose lurasidone 40–160 mg/d, administered once daily in the evening, was associated with significantly reduced daytime sleepiness compared with flexibly dosed quetiapine XR 200–800 mg/d (p = 0.03, effect size = 0.36) at week 32 (month 6 of the continuation study endpoint). Incidence of markedly high sleepiness (ESS > 10) was significantly higher in the quetiapine XR (200–800 mg/d) group compared with the lurasidone (40–160 mg/day) group at both months 3 and 6 visits (p < 0.05). Lurasidone (40–160 mg/d) significantly improved neurocognitive performance compared to quetiapine XR (200–800 mg/d) before (effect size = 0.49) and after adjustment (effect size = 0.45) for sleepiness effect (p = 0.008 and 0.010, respectively). Increased daytime sleepiness was significantly associated with reduced neurocognitive performance (p = 0.019) and quality of well-being (p = 0.05). Our findings suggest that clinicians should actively monitor patients for the presence of daytime sleepiness due in part to its potential impact on neurocognitive performance and well-being.

Abstract
OBJECTIVE This post hoc analysis evaluated the effect of lurasidone on agitation in acutely ill patients with schizophrenia. METHOD Patient-level data were pooled from five 6-week, randomized, double-blind, placebo-controlled studies of fixed-dose, once-daily, oral lurasidone (40, 80, 120, or 160 mg/d). Agitation was assessed with the Positive and Negative Syndrome Scale-Excited Component (PANSS-EC) score, utilizing a mixed model for repeated measurement analysis. RESULTS In patients with higher levels of agitation at baseline (PANSS-EC score≥14; n=773), lurasidone was associated with significantly greater improvement in least-squares (LS) mean PANSS-EC scores versus placebo at Day 3/4 (-1.6 vs -1.0; p<0.05), Day 7 (-2.3 vs -1.6; p<0.05), and at Week 6 endpoint (-5.5 vs -3.8; p<0.001; effect size=0.43). In patients with lower agitation at baseline (PANSS-EC score<14; n=754), LS mean PANSS-EC score change was significantly greater for lurasidone compared with placebo at Day 7 (-0.8 vs -0.1; p<0. 01) through Week 6 endpoint (-1.9 vs -0.9; p<0.001; effect size=0.31). Higher doses of lurasidone were notably more effective than lower doses in patients with more severe agitation at study baseline. CONCLUSION In this pooled analysis of 5 short-term studies, lurasidone provided early and sustained reduction in agitation, assessed using the PANSS-EC score, in patients with an acute exacerbation of schizophrenia. Higher doses of lurasidone were particularly effective in patients with more severe agitation at study baseline. Overall, these results suggest that lurasidone may be a useful treatment option for patients exhibiting agitation associated with acute psychotic symptoms of schizophrenia.

Abstract
BACKGROUND Bipolar disorder is a chronic illness with a 2-year recurrence rate of approximately 50% among individuals receiving treatment in the community. The aim of this 18-month, open-label, continuation study was to evaluate the long-term safety and effectiveness of lurasidone in patients who initially presented with a major depressive episode associated with bipolar disorder, and who had completed at least 6 months of initial treatment with lurasidone. METHODS Patients with bipolar I depression were enrolled in one of three 6-week, double-blind, placebo-controlled trials (monotherapy with lurasidone, 1 study; adjunctive therapy with lurasidone; and lithium or valproate, 2 studies). Study completers were eligible for a 6-month, open-label extension study of lurasidone utilizing flexible daily doses of 20-120 mg; extension completers were then eligible for an additional 18 months of continuation treatment with flexible, once-daily doses of lurasidone in the range of 20-80 mg. Concomitant therapy with mood stabilizers was permitted throughout the open-label extension and continuation studies. RESULTS A total of 1199 patients entered, and 941 (78.5%) completed initial, double-blind, acute treatment, of whom 817/941 (86.8%) entered, and 559 (68.4%) completed the 6-month extension study; 122/559 patients (21.8%) entered the 18-month continuation study, of whom 19.7% of discontinued, including 6.6% due to adverse events and 1.6% due to insufficient efficacy. The mean dose of lurasidone during the 18-month continuation study was 61.8 mg/day, and the modal dose was 60 mg/day. Mean change in weight, from acute baseline to 18-month continuation endpoint was +0.8 kg (completers, n = 55); median changes in cholesterol and triglycerides were -3.0 mg/dL and +26.0 mg/dL, respectively. Based on a Kaplan-Meier analysis, the probability of relapse during 18 months of continuation treatment with lurasidone was estimated to be 18.3% in the monotherapy group and 29.1% in the adjunctive therapy group. Improvement in global illness severity was also maintained during 18 months of continuation therapy (CGI-S at continuation baseline, 2.1; 18-month completers, 1.7; LOCF-endpoint, 1.9). CONCLUSIONS Up to 2 years of treatment with lurasidone was safe and well tolerated in this bipolar disorder population presenting with an index episode of depression. Improvement in depressive symptoms was maintained in the majority of patients treated with lurasidone, with relatively low rates of relapse, and with minimal effects on weight and metabolic parameters.
