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...

Several atypical antipsychotic drugs (APDs) have high affinity for the dopamine (DA) D4 receptor, but the relevance to the efficacy for the treatment of cognitive impairment associated with schizophrenia (CIAS) is poorly understood. The aim of this study was to investigate the effects of D4 receptor stimulation or blockade on novel object recognition (NOR) in normal rats and on the sub-chronic phencyclidine (PCP)-induced novel object recognition deficit. The effect of the D4 agonist, PD168077, and the D4 antagonist, L-745,870, were studied alone, and in combination with clozapine and lurasidone...

REVIEW
Robin Murray, Christoph U Correll, Gavin P Reynolds, David Taylor
Available evidence suggests that second-generation atypical antipsychotics are broadly similar to first-generation agents in terms of their efficacy, but may have a more favourable tolerability profile, primarily by being less likely to cause extrapyramidal symptoms. However, atypical antipsychotics are variably associated with disturbances in the cardiometabolic arena, including increased body weight and the development of metabolic syndrome, which may reflect differences in their receptor binding profiles...

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...

BACKGROUND: Cognitive impairment is present in euthymic patients with bipolar disorder and correlates with impairments in everyday functioning. We aimed to examine the efficacy of lurasidone adjunctive therapy compared with treatment as usual (TAU) in improving cognition. METHODS: For this randomised, open-label, pilot study, we recruited patients aged 19-65 years with euthymic bipolar I disorder from the Mood Disorder Centre in UBC Hospital (Vancouver, Canada)...

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)...

OBJECTIVE: To compare adherence with lurasidone to other oral atypical antipsychotics among Medicaid and commercially insured patients with schizophrenia. RESEARCH DESIGN AND METHODS: Administrative claims of patients with schizophrenia treated with atypical antipsychotics (lurasidone, aripiprazole, olanzapine, quetiapine, risperidone, or ziprasidone) from October 2010 to September 2011 were identified from MarketScan Commercial and Medicaid Databases, and were classified by the first (index) antipsychotic...

Lurasidone hydrochloride (LH), the hydrochloride form of lurasidone with a charge-assisted bond N(+)H, is an atypical antipsychotropic agent for the treatment of schizophrenia. As a BCS class II drug, LH has a low oral bioavailability mainly due to its poor water solubility and low dissolution. In order to improve its solubility, amorphization of LH was performed and characterized. Unexpectedly, the dissolution rate of amorphous LH was much lower than that of crystalline LH. In addition, the amorphous LH powders quickly aggregated when contacting the dissolution media (water, 37°C), and formed a sticky gel adhering on the paddle...

Irreversible monoamine oxidase inhibitor (MAOI) antidepressants have significant efficacy in treatment-resistant unipolar depression, but in some instances patients may not achieve remission. Among the adjunctive and augmentation strategies, certain second-generation antipsychotics (SGAs) have approval for inadequate responders to antidepressant therapy, including aripiprazole, brexpiprazole, and quetiapine, with lurasidone and the olanzapine/fluoxetine combination indicated for bipolar depression. Clinicians may eschew SGA options in part due to the limited literature on SGA-MAOI combinations, with only one published case involving aripiprazole, and none for olanzapine, lurasidone, or brexpiprazole...

A Luoni, J Richetto, L Longo, M A Riva
Prenatal maternal infection represents a risk factor for the development of psychopathologic conditions later in life. Clinical evidence is also supported by animal models in which the vulnerability to develop a schizophrenic-like phenotype likely originates from inflammatory processes as early as in the womb. Prenatal immune challenge, for example, induces a variety of long-term behavioral alterations in mice, such as deficits in recognition and spatial working memory, perseverative behaviors and social impairments, which are relevant to different symptom clusters of schizophrenia...

OBJECTIVE: When planning a clinical study, evidence on the treatment effect is often available from previous studies. However, this evidence is mostly ignored for the analysis of the new study. This is unfortunate, since using it could lead to a smaller study without compromising power. We describe a design that addresses this issue. METHODS: We use a Bayesian meta-analytic model to incorporate the available evidence in the analysis of the new study. The shrinkage estimate for the new study integrates the evidence from the other studies...

REVIEW
Danish Mahmood
Histamine H3 receptors are present as autoreceptors on histaminergic neurons and as heteroreceptors on nonhistaminergic neurones. They control the release and synthesis of histamine and several other key neurotransmitters in the brain. H3 antagonism may be a novel approach to develop a new class of antipsychotic medications given the gathering evidence reporting therapeutic efficacy in several central nervous system disorders. Several medications such as cariprazine, lurasidone, LY214002, bexarotene, rasagiline, raloxifene, BL-1020 and ITI-070 are being developed to treat the negative symptoms and cognitive impairments of schizophrenia...
