AbstractBackgroundLurasidone is approved for the treatment of bipolar depression both as monotherapy and adjunctive therapy with lithium or valproate (Li/VPA). The aim of these analyses was to evaluate the prevalence of treatment-emergent mania (TEM) and worsening of mania symptom severity in clinical trials of both adult and pediatric patients with bipolar depression treated with lurasidone.MethodIn these post-hoc analyses, TEM and change in manic symptom severity as measured by the Young Mania Rating Scale (YMRS) were evaluated in two double-blind (DB), 6-week studies in adults of lurasidone monotherapy, 20–60 mg/d (n=161) and 80–120 mg/d (n=162) vs. placebo (n=162), and adjunctive therapy of lurasidone 20–120 mg/d + Li/VPA (n=179) vs. placebo + Li/VPA (n=161). Prevalence of TEM was also evaluated in a 6-month, open-label (OL) extension study of adults treated with lurasidone monotherapy (n=316) or adjunctive therapy (n=497). In pediatric patients (ages 10–17) TEM and change in manic symptoms was evaluated in a DB 6-week study of lurasidone monotherapy (n=173) vs. placebo (n=170) and in a 24-month OL extension study. TEM was defined as an adverse event of mania or hypomania and/or having a YMRS score =16 at 2 consecutive post-baseline weekly visits (or the final assessment) in short-term studies or 1 post-baseline monthly visit in long-term studies.ResultsAdult studies: In short-term studies, TEM rates were comparable in patients treated with lurasidone monotherapy 20–60 mg/d (3.7%) and 80–120 mg/d (1.9%) vs. placebo (1.9%). TEM rates were also comparable in patients treated with lurasidone 20–120 mg/d (1.1%) adjunctive to Li/VPA vs. placebo + Li/VPA (1.2%). In the monotherapy study, significant reduction in YMRS score was observed at study endpoint for the 20–60 mg/d group compared to placebo (−1.9 vs. −1.3; p<0.05) with similar improvement relative to placebo in the 80–120 mg/d group. Change for YMRS score was comparable for lurasidone and placebo in the adjunctive study. In long-term studies, 1.3% of adult patients treated with lurasidone monotherapy (n=316) met criteria for mania, and 3.8% of patients on adjunctive lurasidone therapy (n=497) met TEM criteria. Pediatric studies: TEM rates were comparable in patients treated with lurasidone vs. placebo (1.7% vs. 2.3%). LS mean reduction in symptoms of mania from baseline to week 6 was significantly greater for lurasidone vs. placebo on YMRS score (−2.0 vs. −1.1; p<0.05). Pediatric long-term studies: After two years of OL treatment with lurasidone, 5.2% of patients met TEM criteria. Mean change in YMRS total score from DB baseline to Month 24 continued to improve (−2.0).ConclusionsShort-term and long-term treatment with lurasidone demonstrated significant improvement in manic symptoms and was not associated with an increased risk of TEM in either adult or pediatric patient populations compared to rates reported in clinical populations of patients.FundingSunovion Pharmaceuticals Inc.

Abstract:Background:Among patients with depressive disorders, the prevalence of metabolic syndrome (MetS) is estimated to range from 35-40% and has been associated with increased mortality rates. The aim of this post-hoc analysis was to assess the effect of treatment with lurasidone on the prevalence of MetS in patients with bipolar depression.Method:Lurasidone data (dose range, 20-120 mg/d) used in the current analyses consisted of 3 double-blind (DB), placebo-controlled, 6-week studies in adults with bipolar I depression (total N=1,192), consisting of 1 monotherapy, and 2 adjunctive therapy trials with lithium or valproate. Patients who completed the short-term trials continued into a 6-month open-label (OL) extension study, with 6-month (LOCF-endpoint) data available on 274 patients treated with lurasidone monotherapy, and 436 patients treated with lurasidone adjunctive therapy. Also analyzed was a recurrence prevention study in stabilized bipolar patients who completed up to 20 weeks of OL adjunctive treatment with lurasidone, and then were randomized to 28 weeks of DB adjunctive therapy with lurasidone or placebo (N=497). MetS was defined based on NCEP ATP III criteria (2005 revision).Results:In the short-term monotherapy and adjunctive therapy studies, the proportion of patients at baseline meeting NCEP III criteria for MetS were 27.6% and 23.6%, respectively, for lurasidone, and 23.8% and 25.1%, respectively, for placebo; and at week 6 (LOCF) the proportion with MetS was 27.5% and 26.6%, respectively, for lurasidone and 29.9% and 20.2%, respectively, for placebo. The proportion of patients who did not meet MetS criteria at baseline but developed MetS at week 6 (LOCF) was similar for lurasidone vs. placebo in the monotherapy study (9.9% vs. 11.6%); and in the two adjunctive therapy studies (10.3% vs. 8.3%). During the 6-month OL extension study, the proportion of patients treated with lurasidone monotherapy and adjunctive therapy who did not meet MetS criteria at OL baseline but developed MetS at month 6 (LOCF) was 11.7% and 11.9%, respectively. Conversely, the proportion of patients who met MetS criteria at OL baseline, but no longer met criteria at month 6 (LOCF) was 9.5% and 7.7%, respectively. In the 20-week, OL phase of the recurrence prevention study, the proportion of patients treated with adjunctive lurasidone who did not meet MetS criteria at OL baseline but developed MetS at endpoint was 11.5% (LOCF). After up to 28 weeks of DB treatment, the proportion of patients who did not meet MetS criteria at DB baseline but developed MetS at endpoint was 9.0% in the adjunctive lurasidone group, and 10.5% in the adjunctive placebo group (LOCF).Conclusion:This post-hoc analysis found that short- and long-term treatment with lurasidone was associated with a relatively low risk for the development of metabolic syndrome in patients with bipolar I disorder. These findings are consistent with similar analyses in patients with schizophrenia.Funding Acknowledgements:Supported by funding from Sunovion Pharmaceuticals Inc.

AbstractBackgroundBipolar disorder frequently has an early onset, with an estimated 1.8% prevalence of bipolar I disorder in children and adolescents. Childhood onset of bipolar disorder is typically associated with a chronic, severe, and disabling course of illness. Relatively few prospective studies are available that evaluate the long-term efficacy of atypical antipsychotics in achieving and sustaining response or remission in pediatric patients with bipolar depression. Lurasidone has been approved by the FDA as monotherapy for bipolar depression in pediatric patients ages 10–17 years. The aim of the current post-hoc analysis was to evaluate the long-term efficacy of lurasidone in achieving response or remission in children and adolescents with bipolar depression followed over a two-year period.MethodPatients 10–17 years with bipolar I depression who completed a 6-week double-blind (DB) study of lurasidone vs. placebo were eligible to enroll in a two-year, open-label (OL) extension study in which patients were continued on flexibly-dosed lurasidone (20–80 mg/d) or switched from placebo to lurasidone. Efficacy measures included the Children’s Depression Rating Scale, Revised (CDRS-R) and the Clinical Global Impression, Bipolar Depression Severity scale (CGI-BP-S). Functioning was evaluated utilizing the Clinician-rated Children’s Global Assessment Scale (CGAS) score, with a score >70 indicating no clinically meaningful functional impairment. Responder criteria were met if a patient achieved criteria = 50% reduction from DB baseline in the CDRS-R total score: remission criteria were met if a patient achieved a CDRS-R Total Score =28 and a YMRS total score =8 and CGI-BP-S depression score =3, and a patient was considered to have met recovery criteria if they achieved remission with a CGAS score >70. In addition, a more stringent outcome, sustained remission, was also analyzed, which required a patient to meet remission criteria for =24 consecutive weeks.ResultsA total of 306 patients completed the 6-week DB study and entered the extension study; 195 (63.7%) patients completed one year of treatment and 168 (54.9%) patients completed two years of treatment. Responder rates at OL baseline, one year, and two years were: 51.0%, 88.4% and 91.1%, respectively; remission rates were 24.3%, 61.3%, and 75.6%, respectively; and recovery rates were 17.7%, 53.8%, and 73.8%. On a Pearson correlation analysis, there was a strong inverse relationship (r = −0.71) between CDRS-R total score, and global functioning as measured by the CGAS. Sustained remission was achieved by 37.2% of patients at one year and 57% of patients after two years.ConclusionsIn children and adolescents with bipolar depression, up to 2 years of treatment with lurasidone was associated with continued improvement in depressive symptoms, resulting in progressively higher rates of response, remission, recovery, and the more rigorously calculated outcome of sustained remission.FundingSunovion Pharmaceuticals Inc.

Context: The use of creatine as a dietary supplement has become increasingly popular over the past several decades. Despite the popularity of creatine, questions remain with regard to dosing, effects on sports performance, and safety. Evidence Acquisition: PubMed was searched for articles published between 1980 and January 2017 using the terms creatine, creatine supplementation, sports performance, and dietary supplements. An additional Google search was performed to capture National Collegiate Athletic Association–specific creatine usage data and US dietary supplement and creatine sales. Study Design: Clinical review. Level of Evidence: Level 4. Results: Short-term use of creatine is considered safe and without significant adverse effects, although caution should be advised as the number of long-term studies is limited. Suggested dosing is variable, with many different regimens showing benefits. The safety of creatine supplementation has not been studied in children and adolescents. Currently, the scientific literature best supports creatine supplementation for increased performance in short-duration, maximal-intensity resistance training. Conclusion: While creatine appears to be safe and effective for particular settings, whether creatine supplementation leads to improved performance on the field of play remains unknown.

ObjectiveThis phase I study investigated pharmacokinetic (PK) and pharmacodynamic (PD) profiles of natalizumab in pediatric patients with relapsing-remitting MS (RRMS).MethodsPediatric patients with RRMS who were prescribed natalizumab 300 mg IV every 4 weeks were enrolled. Blood samples were collected on days 1, 2, 8, 15, and 22 and at weeks 4, 8, 12, and 16 to estimate PK parameters; PD properties were evaluated by measuring α4-integrin saturation and lymphocyte counts over time. Natalizumab's safety profile was also evaluated.ResultsPK parameters were similar to those reported in adult patients; natalizumab concentrations peaked approximately 1 day after infusion in most of the participants (Cmax 142.9 μg/mL, AUClast 47389.4 hr*μg/mL), followed by a biphasic decline with a rapid distribution phase and a slow elimination phase, with a terminal half-life of 215.1 hours. In terms of PD, both time course and magnitude of α4-integrin saturation and increase in lymphocyte counts were similar to those observed in adults. During the 16-week study follow-up, 3 adverse events attributed to natalizumab were observed; no unexpected safety events occurred.ConclusionsPK profile, α4-integrin saturation, lymphocyte counts, and safety observed in these pediatric patients are comparable to those reported in adults.Classification of evidenceThis study provides Class I evidence that natalizumab PK/PD parameters and safety profile are similar in adults and pediatric patients in the short term. Longer studies, also including a larger number of younger subjects (aged 10–12 years), are required to further inform about long-term PK and PD parameters in pediatric patients with MS.

The effectiveness of using accession mixtures of Stylosanthes spp. to manage anthracnose (Colletotrichum gloeosporioides) in pastures in northern Australia was examined during three consecutive years. Two mixtures containing six accessions were compared with the components grown as pure stands. No significant differences in anthracnose incidence (proportion of infected plants/plot) were indicated between the two mixtures and the mean incidence of their respective components grown in pure swards. Areas under the disease progress curves for the accessions were not significantly different between pure and mixed stands of the cultivars other than Seca and Verano. Resistant cultivar Seca developed more disease in a mixture than in a pure stand, and moderately resistant Verano had less disease in a mixture than in a pure stand. In the short term, no apparent anthracnose control advantage is achieved in highly susceptible accessions of Stylosanthes spp. when they are included in mixtures with less susceptible accessions. Long term studies involving grazing animals are necessary to adequately evaluate control of this disease through the use of mixtures.

AbstractBackgroundEffective treatments for patients with high levels of negative symptoms of schizophrenia are lacking. Brexpiprazole is a serotonin–dopamine activity modulator that is a partial agonist at 5-HT1A and dopamine D2 receptors, and an antagonist at 5-HT2A and noradrenaline alpha1B/2C receptors, all with subnanomolar potency. Long-term treatment with brexpiprazole demonstrated broad efficacy across all five Marder factor groupings, including positive, negative, disorganized thoughts, uncontrolled hostility/excitement, and anxiety/depression. This post-hoc analysis of long-term effects of brexpiprazole in patients with clinically relevant levels of negative symptoms of schizophrenia is based on data from two similarly designed short-term, placebo-controlled studies (Vector; NCT01396421 or Beacon; NCT01393613) for the brexpiprazole-treated patients who continued into an open-label extension study (Zenith; NCT01397786).MethodsIn the short-term studies, patients with acute schizophrenia were randomly assigned to fixed once-daily doses of brexpiprazole 0.25mg (Vector), 1mg (Beacon), 2mg , 4mg or placebo for 6weeks. The long-term study was an open-label, 52-week (amended to 26weeks), safety extension study with flexible-dose (1–4mg/day) brexpiprazole. The post-hoc analyses were performed on brexpiprazole-treated patients from the short-term studies who continued into the long-term study, and who had clinically relevant negative symptoms, defined as PANSS Factor Score for Negative Symptoms (PANSS-FSNS; N1, N2, N3, N4, G7, G16) of ≥24, and score of ≥4 on at least two of three core negative symptom PANSS items at randomization in the parent study. The outcome of the analysis included change from baseline to up to 58weeks in PANSS-FSNS, PANSS Total, and PSP. Safety was also assessed.ResultsA total of 187 patients with clinically relevant levels of negative symptoms in the parent study rolled-over into the open-label extension study and were available for analysis. Eighty-three of these patients remained in the studies for 58weeks. Due to the study amendment, not all patients had the opportunity of complete 52weeks of open-label treatment. Baseline PANSS Total score was 104.4, while baseline PANSS-FSNS was 27.6 and baseline PSP Total score was 41.3. Mean change (SD) from baseline in PANSS-FSNS was –10.9 (5.0), and –44.2 (17.5) for PANSS Total score at Week 58. Change from baseline (SD) to Week 58 for PSP Total score was 24.8 (12.9) with improvement in all domains (socially useful activities, personal and social relationship, self-care, and disturbing and aggressive behaviors). The TEAEs reported ≥5% were schizophrenia (18.9%), insomnia (8.6%), weight increased (5.9%) and akathisia (5.9%).ConclusionThis post-hoc analysis suggests that brexpiprazole has long-term effectiveness on negative symptoms and functioning in patients with schizophrenia and clinically relevant levels of negative symptoms.Funding Acknowledgements: The study was funded by Otsuka Pharmaceutical Development & Commercialization Inc. and H.
