Association between cumulative exposure periods of flupentixol or any antipsychotics and risk of lung cancer. COMMUNICATIONS MEDICINE 2023; 3:126.

Abstract
BACKGROUND Preclinical evidence suggests that certain antipsychotic medications may inhibit the development of lung cancer. This study aims to investigate the association between incident lung cancer and different cumulative exposure periods of flupentixol or any antipsychotics. METHODS Using electronic health records from the Hospital Authority in Hong Kong, this nested case-control study included case participants aged 18 years or older with newly diagnosed lung cancer after initiating antipsychotics between January 1, 2003, and August 31, 2022. Each case was matched to up to ten controls of the same sex and age, who were also antipsychotic users. Multivariable conditional logistic regression models were conducted to quantify the association between lung cancer and different cumulative exposure times of flupentixol (0-365 days [ref]; 366-1825 days; 1826+ days) and any antipsychotics (1-365 days [ref]; 366-1825 days; 1826+ days), separately. RESULTS Here we show that among 6435 cases and 64,348 matched controls, 64.06% are males, and 52.98% are aged 65-84 years. Compared to patients with less than 365 days of exposure, those with 366-1825 days of exposure to flupentixol (OR = 0.65 [95% CI, 0.47-0.91]) and any antipsychotics (0.42 [0.38-0.45]) have a lower risk of lung cancer. A decreased risk is observed in patients who have 1826+ days of cumulative use of any antipsychotics (0.54 [0.47-0.60]). CONCLUSIONS A reduced risk of lung cancer is observed in patients with more than one year of exposure to flupentixol or any antipsychotics. Further research on the association between lung cancer and other antipsychotic agents is warranted.

Abstract
A meta-analysis of the results of 45 factor analyses (n = 22,812) of the Positive and Negative Syndrome Scale (PANSS) was conducted. Meta-analyses of the PANSS was conducted using both a co-occurrence similarity matrix and reproduced correlations. Both methods produced similar results. Five factors (Positive Symptoms, Negative Symptoms, Disorganization, Affect and Resistance) emerged clearly across both analyses. The factors and the items defining them were Positive Symptoms (P1 Delusions, G9 Unusual thought content, P3 Hallucinatory behavior, P6 Suspiciousness and persecution, P5 Grandiosity), Negative Symptoms (N2 Emotional withdrawal, N1 Blunted affect, N4 Passive apathetic social withdrawal, N6 Lack of spontaneity, N3 Poor rapport, G7 Motor retardation, G16 Active social avoidance), Disorganization often termed Cognitive (P2 Conceptual disorganization, G11 Poor attention, N5 Difficulty in abstract thinking, G13 Disturbance of volition, N7 Stereotyped thinking, G5 Mannerisms/posturing, G15 Preoccupation, G10 Disorientation), Affect often termed Depression-Anxiety (G2 Anxiety, G6 Depression, G3 Guilt feelings, G4 Tension, G1 Somatic concern) and a small fifth factor that might be characterized as Resistance or Excitement/Activity (P7 Hostility, G14 Poor impulse control, P4 Excitement, G8 Uncooperativeness). Items G1, G4, G10, P5, G5, G15 may not be core items for the PANSS factors and G12 lack of judgment is not a core item. Results of the PANSS meta-analyses were relatively similar to those for meta-analysis of both the BPRS and BPRS-E all of which contain the original 18 BPRS items. The PANSS is distinguished by a much larger number of items to clearly define and measure Negative Symptoms as well as a sufficient number of items to much more clearly identify a Disorganization factor than the BPRS or BPRS-E.

Abstract
Cognitive impairment represents a core feature of schizophrenia. Uncertainty about demonstrable benefits of available antipsychotics on cognition remains an important clinical question relevant to patients' quality of life. The aim of our multi-center, randomized, double-blind "Neuroleptic Strategy Study" (NeSSy) was to compare the effectiveness of selected antipsychotics, conventionally classified as second- (SGAs) (haloperidol, flupentixol) and first generation antipsychotics (FGAs) (aripiprazole, olanzapine, quetiapine), on quality of life in schizophrenia. The effects on cognitive deficits represented a secondary outcome. We used an innovative double randomization for assignment of treatment group, and followed the patients with a neurocognitive test-battery upon six and 24 weeks of treatment. Psychopathology and quality of life were assessed using CGI, PANSS and SF-36. Assessment of cognitive performance was conducted in 114 of the 136 randomized patients. The SGA group (N = 62) showed beneficial effects of small to moderate effect size on cognition during the initial six weeks of treatment (executive functions, verbal fluency) and at 24 weeks (executive functions, working memory). In contrast, the FGA group (N = 52) showed moderately improved executive function, but a decline in verbal fluency at six weeks, with significant declines of moderate to large effect size in executive function, verbal learning and memory, and verbal fluency at 24 weeks. Our study indicates that SGAs present an advantage over FGAs regarding cognitive function during a medium-term treatment for schizophrenia. The results further emphasize a distinction between progression to detrimental effects of FGAs with prolonged treatment in contrast to more persistent cognitive benefits with SGA treatment.

Antipsychotic drugs for patients with schizophrenia and predominant or prominent negative symptoms: a systematic review and meta-analysis. Eur Arch Psychiatry Clin Neurosci 2018; 268:625-639.

Abstract
BACKGROUND Negative symptoms are the core of schizophrenia, but whether antipsychotics are efficacious for their treatment is unclear. Moreover, there is debate whether patients in relevant trials should have predominant negative symptoms or whether prominent negative symptoms are also acceptable. METHODS We systematically reviewed randomised, blinded antipsychotic drug trials in patients with schizophrenia and either predominant or prominent negative symptoms (last search Dec 12, 2017). Separate pairwise meta-analyses were conducted in these two populations. The primary outcome was negative symptoms. Depressive, symptoms, positive symptoms, and extrapyramidal side-effects were analysed as causes of secondary negative symptoms. FINDINGS We included 21 randomized-controlled trials with 3451 participants which revealed the following significant differences in the primary outcome: in patients with predominant negative symptoms amisulpride was superior to placebo (N = 4; n = 590, SMD 0.47, CI 0.23, 0.71), olanzapine was superior to haloperidol in a small trial (n = 35) and cariprazine outperformed risperidone (N = 1, n = 456, SMD - 0.29, CI - 0.48, - 0.11). In patients with prominent negative symptoms, olanzapine and quetiapine were superior to risperidone in single trials. Overall, studies in prominent negative symptoms were potentially more confounded by improvements of secondary negative symptoms. INTERPRETATION Amisulpride is the only antipsychotic that outperformed placebo in the treatment of predominant negative symptoms, but there was a parallel reduction of depression. Cariprazine was better than risperidone in a large trial that was well-controlled for secondary negative symptoms, but the trial was sponsored by its manufacturer. Future trials should apply scientifically developed definitions such as the deficit syndrome and the persistent negative symptoms concept.

Abstract
BACKGROUND Treatment during first-episode psychosis (FEP) or early schizophrenia may affect the rates of relapse and remission, as well as cognitive functioning, over time. Prolonged duration of psychosis is associated with a poor prognosis, but the effects of treatment in patients with FEP or early schizophrenia on the long-term outcomes are not well defined. OBJECTIVE To understand the long-term effects of treatment with antipsychotic agents on remission, relapse, and cognition in patients with FEP or early schizophrenia. METHODS Using PubMed and Scopus databases, a systematic review was undertaken of articles published between January 1, 2000, and May 20, 2015, that reported randomized and nonrandomized prospective clinical trials on the long-term effects of oral or long-acting injectable antipsychotics on measures of relapse, remission, or cognition in patients with FEP or early schizophrenia. For comparative purposes, trials reporting the effects of later intervention with antipsychotics in patients with longer disease history were also evaluated. Titles, abstracts, and full-text articles were independently screened for eligibility by all the authors based on the predefined criteria. RESULTS Nineteen studies met inclusion criteria: 13 reported long-term outcomes of relapse, remission, or cognition following antipsychotic treatment in patients with FEP and six reported on patients with a longer disease history. Antipsychotic treatment in patients with FEP produced high rates of remission in the year following treatment initiation, and untreated FEP reduced the odds of later achieving remission. Maintenance therapy was more effective than treatment discontinuation or intermittent/guided discontinuation in preventing relapse. Initiating antipsychotic treatment in patients with FEP also produced sustained cognitive improvement for up to 2 years. Antipsychotic therapy also reduced the risk or rate of relapse in patients with a longer disease history, with outcomes in one study favoring a long-acting injectable formulation over an oral antipsychotic. CONCLUSION Treatment of patients with FEP is associated with benefits in the long-term outcomes of remission, relapse, and cognition. More long-term studies of treatment in patients with FEP are needed to confirm these findings.

Abstract
In the last 25 years, the Positive and Negative Syndrome Scale (PANSS) has been largely used to assess schizophrenia symptom intensity, but little information is available on how this scale was generally applied when evaluating the efficacy of schizophrenia therapies in randomized clinical trials. In the attempt to address this topic, a systematic PubMed Search was carried out using the keywords "PANSS" and "Randomized Clinical Trials". The analysis of retrieved articles highlighted that PANSS has constituted a suitable psychometric instrument to investigate the efficacy of pharmacological and non-pharmacological therapies. However, the information potentially provided by this scale was only partially reported in research articles, when characterizing the symptomatic features of patients at baseline. Furthermore, a consensus is needed to identify methodological strategies that may properly adapt PANSS-subscale structure with the symptomatic profiles of individuals enrolled in randomized controlled trials. The possibility that PANSS interview procedures and enrollment eligibility criteria may influence the symptomatic composition of patients involved in these studies is also discussed.

Abstract
Painful legs and moving toes syndrome is rare. It is predominantly diagnosed in middle-aged adults following a history of spinal cord surgery or trauma. The syndrome consists of abnormal repetitive movements, most commonly in the lower extremities, accompanied by pain in the affected limb. Pain usually precedes the movements. We report a case in a young patient that we believe was induced by the intake of a low-potency neuroleptic, which was prescribed to him for anxiety. The patient was treated with carbamazepine with mild relief of pain and later on with botulinum injection, which significantly reduced the movements and mildly improved the pain. After stopping the treatment, the beneficial effect lasted for about 3 months after which his condition gradually returned to its initial state.

Abstract
BACKGROUND Long-acting depot injections of drugs such as flupenthixol decanoate are extensively used as a means of long-term maintenance treatment for schizophrenia. OBJECTIVES To evaluate the effects of flupenthixol decanoate in comparison with placebo, oral antipsychotics and other depot neuroleptic preparations for people with schizophrenia and other severe mental illnesses, in terms of clinical, social and economic outcomes. SEARCH METHODS We identified relevant trials by searching the Cochrane Schizophrenia Group Trials Register in March 2009 and then for this update version, a search was run in April 2013. The register is based on regular searches of CINAHL, EMBASE, MEDLINE and PsycINFO. References of all identified studies were inspected for further trials. We contacted relevant pharmaceutical companies, drug approval agencies and authors of trials for additional information. SELECTION CRITERIA All randomised controlled trials that focused on people with schizophrenia or other similar psychotic disorders where flupenthixol decanoate had been compared with placebo or other antipsychotic drugs were included. All clinically relevant outcomes were sought. DATA COLLECTION AND ANALYSIS Review authors independently selected studies, assessed trial quality and extracted data. For dichotomous data we estimated risk ratios (RR) with 95% confidence intervals (CI) using a fixed-effect model. Analysis was by intention-to-treat. We summated normal continuous data using mean difference (MD), and 95% CIs using a fixed-effect model. We presented scale data only for those tools that had attained prespecified levels of quality. Using Grading of Recommendations Assessment, Development and Evaluation (GRADE) we created 'Summary of findings tables and assessed risk of bias for included studies. MAIN RESULTS The review currently includes 15 randomised controlled trials with 626 participants. No trials compared flupenthixol decanoate with placebo.One small study compared flupenthixol decanoate with an oral antipsychotic (penfluridol). Only two outcomes were reported with this single study, and it demonstrated no clear differences between the two preparations as regards leaving the study early (n = 60, 1 RCT, RR 3.00, CI 0.33 to 27.23,very low quality evidence) and requiring anticholinergic medication (1 RCT, n = 60, RR 1.19, CI 0.77 to 1.83, very low quality evidence).Ten studies in total compared flupenthixol decanoate with other depot preparations, though not all studies reported on all outcomes of interest. There were no significant differences between depots for outcomes such as relapse at medium term (n = 221, 5 RCTs, RR 1.30, CI 0.87 to 1.93, low quality evidence), and no clinical improvement at short term (n = 36, 1 RCT, RR 0.67, CI 0.36 to 1.23, low quality evidence). There was no difference in numbers of participants leaving the study early at short/medium term (n = 161, 4 RCTs, RR 1.23, CI 0.76 to 1.99, low quality evidence) nor with numbers of people requiring anticholinergic medication at short/medium term (n = 102, 3 RCTs, RR 1.38, CI 0.75 to 2.25, low quality evidence).Three studies in total compared high doses (100 to 200 mg) of flupenthixol decanoate with the standard doses (˜40mg) per injection. Two trials found relapse at medium term (n = 18, 1 RCT, RR 1.00, CI 0.27 to 3.69, low quality evidence) to be similar between the groups. However people receiving a high dose had slightly more favourable medium term mental state results on the Brief Psychiatric Rating Scale (BPRS) (n = 18, 1 RCT, MD -10.44, CI -18.70 to -2.18, low quality evidence). There was also no significant difference in the use of anticholinergic medications to deal with side effects at short term (2 RCTs n = 47, RR 1.12, CI 0.83 to 1.52 very low quality evidence). One trial comparing a very low dose of flupenthixol decanoate (˜6 mg) with a low dose (˜9 mg) per injection reported no difference in relapse rates (n = 59, 1 RCT, RR 0.34, CI 0.10 to 1.15, low quality evidence). AUTHORS' CONCLUSIONS In the current state of evidence, there is nothing to choose between flupenthixol decanoate and other depot antipsychotics. From the data reported in clinical trials, it would be understandable to offer standard dose rather than the high dose depot flupenthixol as there is no difference in relapse. However, data reported are of low or very low quality and this review highlights the need for large, well-designed and reported randomised clinical trials to address the effects of flupenthixol decanoate.

Abstract
Introduction Antipsychotics (AP) induce weight gain. However, reviews and meta-analyses generally are restricted to second generation antipsychotics (SGA) and do not stratify for duration of AP use. It is hypothesised that patients gain more weight if duration of AP use is longer. Method A meta-analysis was conducted of clinical trials of AP that reported weight change. Outcome measures were body weight change, change in BMI and clinically relevant weight change (7% weight gain or loss). Duration of AP-use was stratified as follows: ≤6 weeks, 6–16 weeks, 16–38 weeks and >38 weeks. Forest plots stratified by AP as well as by duration of use were generated and results were summarised in figures. Results 307 articles met inclusion criteria. The majority were AP switch studies. Almost all AP showed a degree of weight gain after prolonged use, except for amisulpride, aripiprazole and ziprasidone, for which prolonged exposure resulted in negligible weight change. The level of weight gain per AP varied from discrete to severe. Contrary to expectations, switch of AP did not result in weight loss for amisulpride, aripiprazole or ziprasidone. In AP-naive patients, weight gain was much more pronounced for all AP. Conclusion Given prolonged exposure, virtually all AP are associated with weight gain. The rational of switching AP to achieve weight reduction may be overrated. In AP-naive patients, weight gain is more pronounced.

Flupentixol use and adverse reactions in comparison with other common first- and second-generation antipsychotics: data from the AMSP study. Eur Arch Psychiatry Clin Neurosci 2014; 264:131-41. [PMID: 23835526 DOI: 10.1007/s00406-013-0419-y] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2012] [Accepted: 06/25/2013] [Indexed: 02/06/2023]
Abstract
This study compares the first-generation antipsychotic (FGA) flupentixol to haloperidol and common second-generation antipsychotics (SGAs) as to drug utilization and severe adverse drug reactions (ADRs) in clinical treatment of schizophrenia inpatients using data from the drug safety program Arzneimittelsicherheit in der Psychiatrie (AMSP). AMSP drug utilization and reported ADR data were analyzed. Type and frequency of severe ADRs attributed to flupentixol were compared with haloperidol, clozapine, olanzapine, quetiapine, risperidone and amisulpride in a total of 56,861 schizophrenia inpatients exposed to these drugs. In spite of increasing prescription of SGAs, flupentixol was consistently used in schizophrenic inpatients (about 5 %) over time. Reporting rates of severe ADR ranged from 0.38 to 1.20 % for the individual antipsychotics (drugs imputed alone); flupentixol ranked lowest. The type of ADR differed considerably; as to severe EPMS, flupentixol (0.27 %), such as risperidone (0.28 %), held an intermediate position between haloperidol/amisulpride (0.55/0.52 %) and olanzapine/quetiapine (<0.1 %). The study is a heuristic approach, not a confirmatory test. Flupentixol has a stable place in the treatment of schizophrenia in spite of the introduction of different SGAs. Comparative ADR profiles suggest an intermediate position between FGAs and SGAs for flupentixol in clinical practice.

Cost-effectiveness of long-acting injectable risperidone versus flupentixol decanoate in the treatment of schizophrenia: a Markov model parameterized using administrative data. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2014; 15:133-142.

Abstract
We use longitudinal patient-level data from a German sickness fund with 7.26 million insured in a Markov-simulation model to assess the cost-effectiveness of long-acting injectable risperidone (LAI-RIS) compared with long-acting injectable flupentixol (LAI-FLX) in the long-term management of schizophrenia. We simulate treatment costs from the payer's perspective, hospitalization, the probability to be prescribed co-medication, and treatment discontinuation over a 2-year time horizon. Model inputs were derived from 935 patients hospitalized with schizophrenia between 2005 and 2008 who received either LAI-RIS or LAI-FLX for at least 1 month. After 2 years, 89.4% (95.8%) of patients who were initiated on LAI-RIS (LAI-FLX) discontinued the initial regimen. The number of days spent in hospital per month and patient was slightly lower with LAI-RIS (1.08 vs. 1.28 days, p<0.001). The proportion of patients receiving side-effect co-medication was lower with LAI-RIS (8.3 vs. 15.0% per month, p<0.001). Mean total costs of treatment per patient and month were 1,015 € under LAI-RIS and 395 € under LAI-FLX, resulting in an ICER of 3,088 € (95% CI [-913 €; 3,551 €]) for an avoided hospital day per patient and month in the base case scenario with a 15.1% probability of LAI-FLX being the dominant treatment strategy. Cost differences were mainly attributable to the higher drug costs of LAI-RIS. The effectiveness of LAI-RIS in preventing hospital days appears to be similar to LAI-FLX, with a slight superiority in side-effect and switching rates. This comes at the cost of substantially higher treatment expenses. From a decision-maker's point of view, the use of health insurance data as a source of input for decision models appears to be a reasonable alternative to models driven by clinical data only.

Abstract
BACKGROUND Flupenthixol, first made available in the UK in 1965, has been used as a treatment for schizophrenia for decades. OBJECTIVES To evaluate the absolute clinical effects of flupenthixol for schizophrenia in comparison with placebo. SEARCH METHODS We searched the Cochrane Schizophrenia Group Trials Register (August 2011), inspected references of all included or excluded studies for further trials, and contacted authors of trials for additional information. SELECTION CRITERIA All randomised controlled trials (RCTs) that compared flupenthixol with placebo for adults with schizophrenia or related disorders by any means of diagnosis. Primary outcomes of interest were clinically important change in global state, mental state and behaviour, and adverse effects. DATA COLLECTION AND ANALYSIS We extracted data from the one included study, discussed any disagreement, documented decisions and contacted the authors of the included study for further information. We analysed binary outcomes using a standard estimation of the risk ratio (RR) and its 95% confidence intervals (CI). For homogenous data we used a fixed-effect model. For rare events we analysed dichotomous data using Peto Odds ratio (OR), again with 95% CIs. MAIN RESULTS We could include only one small (n = 45) study of moderate quality. When the active α-flupenthixol was compared with the inactive placebo or β-flupenthixol groups combined, fewer people in the active treatment group needed additional antipsychotic medication by around four weeks for deterioration in their general state (n = 45, OR 0.19 CI 0.05 to 0.71). There was no clear difference in social functioning at one year (n = 45, RR 1.33 CI 0.91 to 1.96). We found no clear data on mental state and behaviour, adverse effects, service use, satisfaction with treatment or costs. AUTHORS' CONCLUSIONS We were surprised that this well-established drug had so few data from trials investigating its absolute effects. We think this is unlikely to be rectified some 50 years after its launch and know that this would not happen today. However, even though data are very limited, flupenthixol may well be worthy of careful investigation - partly to ensure that this inexpensive active drug is not forgotten.

Abstract
Antipsychotic drugs have various neuropharmacological properties as a result of their structural diversity. Despite their therapeutic benefits, most of the prescribed atypical antipsychotics can induce severe side effects, including weight gain, type II diabetes mellitus, and cardiovascular diseases. Among the developed atypical antipsychotic agents, tetracyclic dibenzodiazepine and thienobenzodiazepine compounds, particularly clozapine and olanzapine, are associated with the greatest weight gain and metabolic disturbances. However, the unique chemical structure of these compounds causes the low risk of side effects reported for typical antipsychotics (e.g. extrapyramidal symptoms and tardive dyskinesia). This report reviews the recent discovery of the potential role of the chemical structure of antipsychotics in their therapeutic properties and metabolic disturbances. By developing structure-activity relationship studies for atypical antipsychotics, we will improve our understanding of the structural modifications of these chemical classes that lead to reduced weight gain, which will be an invaluable step toward the discovery of the next generation of atypical antipsychotics. In this review, we suggest that a novel dibenzodiazepine or thienobenzodiazepine antipsychotic drug with lower affinity for H(1) receptors may significantly advance schizophrenia therapy.

Abstract
BACKGROUND The development of algorithms and guidelines in medicine is widespread. There are six major guidelines used and/or influencing the treatment of schizophrenia in the United States. The impact of these guidelines on clinical practice is difficult to evaluate. Many studies to date show poor adherence to schizophrenia guideline recommendations. OBJECTIVE The purpose of this article is to discuss the rationale for use of guidelines/algorithms in medicine, the importance of schizophrenia guidelines, barriers to using guidelines, and to review key aspects of schizophrenia guidelines most commonly used in the United States. RESULTS Schizophrenia guidelines/algorithms differ somewhat in scope, focus, goals, and recommendations. Each guideline/algorithm has its utility in clinical practice.

Abstract
Schizophrenia is one of the most expensive illnesses. Antipsychotics are an essential component of the acute and preventative treatment of this illness, and long-term treatment is necessary to decrease the risk of psychotic relapse. The efficacy and tolerability of flupentixol was evaluated in a post-marketing surveillance study (PMS) in schizophrenic patients receiving long-term treatment in routine clinical practice. Psychiatrists in office practice treated patients for approximately 10 weeks, with a subsequent follow-up period of up to 18 months. We here report on the follow-up period in 128 patients. The benefit for schizophrenic patients increased with the treatment duration of flupentixol as documented by the Clinical Global Impression (CGI). Subjective quality of life improved during the first study period, and this remained stable in the follow-up period. No increase in body weight was observed during the study. The relapse rate was much lower than in other studies. Anticholinergic medication was necessary for 22.7% of the patients at any time. More than 70% of the psychiatrists involved evaluated the treatment as very good or good. The results of this study suggest that flupentixol is a potent and safe antipsychotic for the long-term treatment of schizophrenia in routine clinical practice.

Paliperidone extended-release for schizophrenia: effects on symptoms and functioning in acutely ill patients with negative symptoms. Schizophr Res 2009; 113:56-64. [PMID: 19560322 DOI: 10.1016/j.schres.2009.05.021] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2008] [Revised: 05/21/2009] [Accepted: 05/22/2009] [Indexed: 11/21/2022]
Abstract
BACKGROUND Most patients with schizophrenia exhibit negative symptoms, even during acute episodes. These difficult-to-treat symptoms are often associated with poor functioning and outcomes. METHODS A post-hoc analysis of pooled data from three 6-week double-blind studies included patients in an acute episode of schizophrenia who received paliperidone extended-release (ER) (3, 6, 9, or 12 mg) or placebo. Based on criteria developed by the authors, patients were stratified by the presence or absence of predominant negative symptoms at baseline (>or=40% of the maximum negative factor score and <40% of the maximum positive factor score on the Positive and Negative Syndrome Scale [PANSS]). RESULTS Although these studies were not designed to examine patients with predominant negative symptoms, the criteria identified 23% of acutely ill patients (270/1193). The mean (SD) baseline PANSS negative symptoms factor score, 27.4 (3.3), was 49% of the maximum; the positive symptoms factor score, 23.7 (2.8), was 33% of the maximum. Completion rates with paliperidone ER (n=195) and placebo (n=75) were 64.6% and 44.0%, respectively. Greater improvements occurred with paliperidone ER vs placebo on PANSS (total, negative and other factors), Clinical Global Impressions-Severity and Personal and Social Performance scores at endpoint (all P values <0.05). Adverse events reported in >or=10% of patients were (paliperidone ER vs placebo): headache (14.4% vs 6.7%), insomnia (13.8% vs 21.3%) and sinus tachycardia (10.3% vs 1.3%). Paliperidone ER treatment was associated with a similar response profile in patients without predominant negative symptoms (paliperidone ER, n=647; placebo, n=276). CONCLUSIONS Schizophrenia patients with predominant negative symptoms were identified in a population of acutely ill patients. Findings of this post-hoc analysis suggest that acutely ill patients with or without predominant negative symptoms respond similarly to treatment with paliperidone ER. No unexpected tolerability findings were observed.
