RESUMEN

Although antipsychotics' mechanisms of action have been thoroughly investigated, they have not been fully elucidated at the network level. We tested the hypothesis that acute pre-treatment with ketamine (KET) and administration of asenapine (ASE) would modulate the functional connectivity of brain areas relevant to the pathophysiology of schizophrenia, based on transcript levels of Homer1a, an immediate early gene encoding a key molecule of the dendritic spine. Sprague-Dawley rats (n = 20) were assigned to KET (30 mg/kg) or vehicle (VEH). Each pre-treatment group (n = 10) was randomly split into two arms, receiving ASE (0.3 mg/kg), or VEH. Homer1a mRNA levels were evaluated by in situ hybridization in 33 regions of interest (ROIs). We computed all possible pairwise Pearson correlations and generated a network for each treatment group. Acute KET challenge was associated with negative correlations between the medial portion of cingulate cortex/indusium griseum and other ROIs, not detectable in other treatment groups. KET/ASE group showed significantly higher inter-correlations between medial cingulate cortex/indusium griseum and lateral putamen, the upper lip of the primary somatosensory cortex, septal area nuclei, and claustrum, in comparison to the KET/VEH network. ASE exposure was associated with changes in subcortical-cortical connectivity and an increase in centrality measures of the cingulate cortex and lateral septal nuclei. In conclusion, ASE was found to finely regulate brain connectivity by modelling the synaptic architecture and restoring a functional pattern of interregional co-activation.

RESUMEN

BACKGROUND: Major depressive disorder (MDD) is the leading cause of disability worldwide. Response to pharmacologic treatment is generally evaluated by traditional clinician- and patient-reported rating scales. Assessing therapeutic efficacy using the Goal Attainment Scale offers a complementary measure that focuses on recovery-oriented outcomes that patients consider valuable and vital to their well-being. This study aimed to examine outcomes using the Goal Attainment Scale adapted for depression (GAS-D). METHODS: A phase 4, single-arm, open-label, multicenter study enrolled patients with MDD who were switching antidepressant medication. Patients received vortioxetine 10-20 mg over 12 weeks. Three specific, measurable, attainable, relevant, and time-bound goals were collaboratively set by patients with their clinicians. One goal was determined by the patient's self-defined objectives; 2 were related to predefined domain categories. Prespecified domains included psychological, motivational, emotional, physical/functional, and cognitive categories. The primary endpoint was the proportion of patients who achieved a GAS-D score ≥ 50 at week 12. Secondary and exploratory endpoints included changes from baseline in several clinical and patient-reported measures of depression and cognitive function. Safety and tolerability were also assessed. RESULTS: At week 12, of the 122 adults participating in the study, 57.8% achieved a GAS-D score ≥ 50. Depression severity, cognitive function, cognitive performance, well-being, employment, and quality of life also significantly improved. Treatment response and remission rates were 65 and 40%, respectively. Vortioxetine was well tolerated, with adverse events consistent with product labeling. CONCLUSIONS: A majority of patients with MDD switching to vortioxetine achieved their treatment goals, including improvement in specific functional outcomes relating to physical and emotional goals, as assessed by the GAS-D and standard patient- and clinician-reported measures. When assayed for convergent validity in a separate analysis, changes in goal scores on the GAS-D were statistically significantly correlated with multiple commonly used clinical measures of depression assessed in this study. The GAS-D approach provides a new patient-centric paradigm for the collaborative development and assessment of progress toward meaningful treatment goals, contributing to a comprehensive evaluation of treatment outcomes in patients with MDD. Longer studies against a control intervention are justified. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02972632 . Registered 21 November 2016.

RESUMEN

BACKGROUND: Antipsychotic agents modulate key molecules of the postsynaptic density (PSD), including the Homer1a gene, implicated in dendritic spine architecture. How the antipsychotic receptor profile, dose, and duration of administration may influence synaptic plasticity and the Homer1a pattern of expression is yet to be determined. METHODS: In situ hybridization for Homer1a was performed on rat tissue sections from cortical and striatal regions of interest (ROI) after acute or chronic administration of three antipsychotics with divergent receptor profile: Haloperidol, asenapine, and olanzapine. Univariate and multivariate analyses of the effects of topography, treatment, dose, and duration of antipsychotic administration were performed. RESULTS: All acute treatment regimens were found to induce a consistently higher expression of Homer1a compared to chronic ones. Haloperidol increased Homer1a expression compared to olanzapine in striatum at the acute time-point. A dose effect was also observed for acute administration of haloperidol. CONCLUSIONS: Biological effects of antipsychotics on Homer1a varied strongly depending on the combination of their receptor profile, dose, duration of administration, and throughout the different brain regions. These molecular data may have translational valence and may reflect behavioral sensitization/tolerance phenomena observed with prolonged antipsychotics.

RESUMEN

OBJECTIVE: To compare the tolerability and efficacy of different antipsychotic cross-titration schedules, using data from a brexpiprazole study (Equator; NCT01668797). METHODS: Patients with schizophrenia were cross-titrated from other antipsychotics to brexpiprazole monotherapy in a 1-4 week open-label conversion phase, then entered a single-blind brexpiprazole treatment phase. Patients were stratified into four "conversion groups," according to the amount of time spent in the conversion phase. Discontinuation rates, treatment-emergent adverse events (TEAEs), and efficacy (Positive and Negative Syndrome Scale [PANSS]) were compared between conversion groups. RESULTS: Of the 404 patients treated with brexpiprazole, the majority (72.0%) spent 22-33 days in the conversion phase. Discontinuation rates due to lack of efficacy or adverse events were low in all conversion groups. Of the 292 patients who successfully switched and completed 8 weeks of brexpiprazole treatment, most were converted to brexpiprazole over 22-33 days (80.1%), and fewer were converted over 1-7 days (2.4%), 8-14 days (6.5%), or 15-21 days (11.0%). The incidence of TEAEs over 8 weeks was lower among those converted over 22-33 days (44.4%) than in other conversion groups (62.5-84.2%), although low patient numbers with shorter conversion times limit the generalizability of this finding. Each conversion group showed comparable improvement in PANSS total score from baseline. CONCLUSION: The majority of patients were cross-titrated to brexpiprazole over a period of 22-33 days, by investigators' choice. Additional data on shorter conversions may help clinicians to choose a switching paradigm that best meets their patients' needs.

RESUMEN

Background: Two open-label, randomized, parallel-arm studies compared pharmacokinetics, safety, and tolerability of aripiprazole once-monthly 400 mg following deltoid vs gluteal injection in patients with schizophrenia. Methods: In the single-dose study, 1 injection of aripiprazole once-monthly 400 mg in the deltoid (n=17) or gluteal (n=18) muscle (NCT01646827) was administered. In the multiple-dose study, the first aripiprazole once-monthly 400 mg injection was administered in either the deltoid (n=71) or gluteal (n=67) muscle followed by 4 once-monthly deltoid injections (NCT01909466). Results: After single-dose administration, aripiprazole exposure (area under the concentration-time curve) was similar between deltoid and gluteal administrations, whereas median time to maximum plasma concentration was shorter (7.1 [deltoid] vs 24.1 days [gluteal]) and maximum concentration was 31% higher after deltoid administration. In the multiple-dose study, median time to maximum plasma concentration for deltoid administration was shorter (3.95 vs 7.1 days), whereas aripiprazole mean trough concentrations, maximum concentration, and area under the concentration-time curve were comparable between deltoid and gluteal muscles (historical data comparison). Multiple-dose pharmacokinetic results for the major metabolite, dehydro-aripiprazole, followed a similar pattern to that of the parent drug for both deltoid and gluteal injection sites. Safety and tolerability profiles were similar after gluteal or deltoid injections. Based on observed data, minimum aripiprazole concentrations achieved by aripiprazole once-monthly 400 mg are comparable with those of oral aripiprazole 15 to 20 mg/d. Conclusions: The deltoid muscle is a safe alternative injection site for aripiprazole once-monthly 400 mg in patients with schizophrenia.

RESUMEN

Background: QUALIFY was a 28-week, randomized, open-label, head-to-head trial that assessed improvements across multiple measures in stable patients with schizophrenia with aripiprazole once-monthly 400 mg vs paliperidone palmitate. Methods: Secondary effectiveness assessments included physician-rated readiness for work using the Work Readiness Questionnaire, the Clinical Global Impression-Severity and Clinical Global Impression-Improvement scales, and quality of life with the rater-blinded Heinrichs-Carpenter Quality of Life Scale. Patients assessed their treatment satisfaction and quality of life with Subjective Well-Being under Neuroleptic Treatment-short version and Tolerability and Quality of Life questionnaires. Results: Odds of being ready for work at week 28 were significantly higher with aripiprazole once-monthly 400 mg vs paliperidone palmitate (adjusted odds ratio, 2.67; 95% CI, 1.39-5.14; P=.003). Aripiprazole once-monthly 400 mg produced numerically or significantly greater improvements from baseline vs paliperidone palmitate in all Quality of Life Scale items. With aripiprazole once-monthly 400 mg vs paliperidone palmitate at week 28, there were significantly more Clinical Global Impression-Severity and Clinical Global Impression-Improvement responders (adjusted odds ratio, 2.26; P=.010, and 2.51; P=.0032) and significantly better Clinical Global Impression-Improvement scores (least squares mean treatment difference, -0.326; 95% CI, -0.60 to -0.05; P=.020). Numerically larger improvements with aripiprazole once-monthly 400 mg vs paliperidone palmitate were observed for patient-rated scales Subjective Well-Being under Neuroleptic Treatment-short version and Tolerability and Quality of Life. Partial correlations were strongest among clinician-rated and among patient-rated scales but poorest between clinician and patient-rated scales. Conclusions: Consistently greater improvements were observed with aripiprazole once-monthly 400 mg vs paliperidone palmitate across all measures. Partial correlations between scales demonstrate the multidimensionality of various measures of improvement. More patients on aripiprazole once-monthly 400 mg were deemed ready to work by the study end.

RESUMEN

BACKGROUND: Long-acting injectable antipsychotics are treatment options for acute and long-term treatment of patients with schizophrenia. In a previously published 12-week randomized, double-blind, placebo-controlled clinical trial of patients with schizophrenia experiencing an acute psychotic episode, aripiprazole once-monthly 400 mg (AOM 400) produced significantly greater improvement than placebo on the primary endpoint, Positive and Negative Syndrome Scale (PANSS) total score at week 10. METHODS: To examine the efficacy of AOM 400 across a broader representation of schizophrenia symptoms, including agitation, a post hoc analysis of this trial was carried out to assess the change in PANSS Marder factor domains (positive symptoms, negative symptoms, disorganized thought, uncontrolled hostility/excitement, and anxiety/depression) and the PANSS excited component (equivalent to Marder factor domain uncontrolled hostility/excitement plus the tension item) by comparing differences in change from baseline between AOM 400 and placebo using a mixed model for repeated measures. RESULTS: The differences between treatment and placebo for all factors were statistically significant, with improvements seen as early as week 1 or 2, and maintained through week 12. Thus, AOM 400, supplemented with oral aripiprazole in the first 2 weeks, showed significantly greater efficacy versus placebo in acutely ill patients with schizophrenia in all 5 Marder illness domains, as well as in agitation as conceptualized by the PANSS excited component score. CONCLUSIONS: These findings indicate that AOM 400 is efficacious across the spectrum of schizophrenia symptoms in acutely ill patients, with implications for both short-term and, by extension, long-term patient outcomes.

RESUMEN

OBJECTIVE: To assess the effects of aripiprazole once-monthly 400 mg (AOM 400) on clinical symptoms and global improvement in schizophrenia after switching from an oral antipsychotic. METHODS: In a multicenter, open-label, mirror-image, naturalistic study in patients with schizophrenia (>1 year, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision [DSM-IV-TR] criteria), changes in efficacy measures were assessed during prospective treatment (6 months) with AOM 400 after switching from standard-of-care oral antipsychotics. During prospective treatment, patients were cross-titrated to oral aripiprazole monotherapy (1-4) weeks followed by open-label AOM 400 (24 weeks). Mean change from baseline of the open-label AOM 400 phase in Positive and Negative Syndrome Scale (PANSS) scores (total, positive and negative subscales) and Clinical Global Impression-Severity (CGI-S) scores; mean CGI-Improvement (CGI-I) score; and proportion of responders (≥30% decrease from baseline in PANSS total score or CGI-I score of 1 [very much improved] or 2 [much improved]) were assessed. RESULTS: PANSS and CGI-S scores improved from baseline (P<0.0001) and CGI-I demonstrated improvement at all time points. By the end of the study, 49.0% of patients were PANSS or CGI-I responders. CONCLUSIONS: In a community setting, patients with schizophrenia who were stabilized at baseline and switched to AOM 400 from oral antipsychotics showed clear improvements in clinical symptoms.

RESUMEN

BACKGROUND: Database analyses have indicated that medical treatment for schizophrenia varies among racial groups. This study assessed antipsychotic use and healthcare utilization across races in Medicaid-insured patients with schizophrenia. METHODS: A Medicaid database of inpatient/outpatient medical claims and outpatient prescription claims for more than 28 million enrollees in 11 geographically diverse states was analyzed. The primary outcome, racial differences in antipsychotic use in 2012, was examined in 5 multivariable logistic regression models: (1) any antipsychotic, (2) first-generation (FG) long-acting injectables (LAIs), (3) FG oral antipsychotics, (4) second-generation (SG) LAIs, and (5) SG oral antipsychotics. RESULTS: Odds ratios and adjusted predicted probabilities were comparable for any antipsychotic use between black and white patients. Black patients were less likely to receive SG oral antipsychotics (P < .001) and more likely to receive SG or FG LAIs (P = .001 and P < .001, respectively) and FG oral antipsychotics (P = .003) vs white patients. Further, black patients had a higher mean number of emergency room visits (P < .001) and a lower mean number of hospitalizations (P < .05) vs white patients; the mean number of physician visits was comparable. CONCLUSIONS: Disparities in antipsychotic use and healthcare utilization across races in patients with schizophrenia warrant further investigation and elimination of these disparities should be a national goal.

RESUMEN

BACKGROUND: Long-acting injectable formulations of antipsychotics are treatment alternatives to oral agents. AIMS: To assess the efficacy of aripiprazole once-monthly compared with oral aripiprazole for maintenance treatment of schizophrenia. METHOD: A 38-week, double-blind, active-controlled, non-inferiority study; randomisation (2:2:1) to aripiprazole once-monthly 400 mg, oral aripiprazole (10-30 mg/day) or aripiprazole once-monthly 50 mg (a dose below the therapeutic threshold for assay sensitivity). ( TRIAL REGISTRATION: clinicaltrials.gov, NCT00706654.) RESULTS: A total of 1118 patients were screened, and 662 responders to oral aripiprazole were randomised. Kaplan-Meier estimated impending relapse rates at week 26 were 7.12% for aripiprazole once-monthly 400 mg and 7.76% for oral aripiprazole. This difference (-0.64%, 95% CI -5.26 to 3.99) excluded the predefined non-inferiority margin of 11.5%. Treatments were superior to aripiprazole once-monthly 50 mg (21.80%, P < or = 0.001). CONCLUSIONS: Aripiprazole once-monthly 400 mg was non-inferior to oral aripiprazole, and the reduction in Kaplan-Meier estimated impending relapse rate at week 26 was statistically significant v. aripiprazole once-monthly 50 mg.

RESUMEN

BACKGROUND: Enhanced patient-provider engagement can improve patient health outcomes in chronic conditions, including major depressive disorder (MDD). OBJECTIVE: We evaluated the impact of a digitally enabled care mobile app, Pathway, designed to improve MDD patient-provider engagement. Patients used a mobile interface to assess treatment progress and share this information with primary care providers (PCPs). METHODS: In this 52-week, real-world effectiveness and feasibility study conducted in primary care clinics, 40 patients with MDD who were recently prescribed antidepressant monotherapy were randomized to use a mobile app with usual care (20/40, 50%) or usual care alone (20/40, 50%). Patients in the app arm engaged with the app daily for 18 weeks; a report was generated at 6-week intervals and shared with the PCPs to facilitate shared treatment decision-making discussions. The patients discontinued the app at week 18 and were followed through year 1. Coprimary outcome measures, assessed via research visits, included change from baseline in the 13-item Patient Activation Measure (PAM-13) and 7-item Patient-Provider Engagement Scale scores at week 18. Additional outcome measures included depression severity (9-item Patient Health Questionnaire [PHQ-9]) and cognitive symptoms (5-item Perceived Deficits Questionnaire-Depression). RESULTS: All 37 patients (app arm: n=18, 49%; usual care arm: n=19, 51%) who completed the 18-week follow-up period (n=31, 84% female, mean age 36, SD 11.3 years) had moderate to moderately severe depression. Improvements in PAM-13 and PHQ-9 scores were observed in both arms. Increases in PAM-13 scores from baseline to 18 weeks were numerically greater in the app arm than in the usual care arm (mean 10.5, SD 13.2 vs mean 8.8, SD 9.4; P=.65). At 52 weeks, differences in PAM-13 scores from baseline demonstrated significantly greater improvements in the app arm than in the usual care arm (mean 20.2, SD 17.7 vs mean 1.6, SD 14.2; P=.04). Compared with baseline, PHQ-9 scores decreased in both the app arm and the usual care arm at 18 weeks (mean 7.8, SD 7.2 vs mean 7.0, SD 6.5; P=.73) and 52 weeks (mean 9.5, SD 4.0 vs mean 4.7, SD 6.0; P=.07). Improvements in 7-item Patient-Provider Engagement Scale and WHO-5 scores were observed in both arms at 18 weeks and were sustained through 52 weeks in the app arm. Improvements in WHO-5 scores at 52 weeks were significantly greater in the app arm than in the usual care arm (41.5 vs 20.0; P=.02). CONCLUSIONS: Patients with MDD will engage with a mobile app designed to track treatment and disease progression. PCPs will use the data generated as part of their assessment to inform clinical care. The study results suggest that an app-enabled clinical care pathway may enhance patient activation and benefit MDD management.

RESUMEN

Impulsivity in schizophrenia is a risk factor for suicide, drug abuse, and other risk-taking behaviors. This exploratory, multicenter, randomized, double-blind, functional magnetic resonance imaging (fMRI) study assessed the effects of brexpiprazole on brain regions that control impulsive behavior. Thirty-eight outpatients with stable schizophrenia and impulsivity symptoms were randomized to 6 weeks of brexpiprazole 2 or 4 mg/day. The prespecified outcome measure was blood oxygen-level dependent (BOLD) activation in the right ventrolateral prefrontal cortex (VLPFC) during performance of tasks associated with inhibition/control of impulsivity: the go/no-go task and stop-signal task. Secondary objectives evaluated the efficacy, safety and tolerability of brexpiprazole. Over 6 weeks, patients receiving brexpiprazole had no statistically significant change in right VLPFC BOLD activation during the go/no-go task, but showed a significant decrease in right VLPFC BOLD activation during the stop-signal task. Brexpiprazole was also associated with significantly improved stop-signal reaction time (SSRT). No worsening of psychiatric symptoms, functioning, or impulsivity occurred in these patients. No unexpected safety or tolerability concerns were identified. In conclusion, brexpiprazole treatment among patients with schizophrenia and impulsivity was associated with decreased right VLPFC activation and decreased SSRT, supportive of a benefit of brexpiprazole on inhibition-related brain activation and behavior.

RESUMEN

INTRODUCTION: Isolated sphenoid sinus inflammatory diseases (ISSIDs) are responsible for about 75% of isolated sphenoid sinus opacifications. Computer tomography (CT) and magnetic resonance imaging (MRI) should be used in a complementary manner for the assessment of ISSIDs. This evaluation sheds some light on the extent of disease and intracranial and intra-orbital involvement. MATERIALS AND METHODS: The current study aimed to evaluate the medication histories of 14 patients who underwent endoscopic sinus surgery (ESS) for ISSIDs within 2015-2018. This assessment was carried out to analyze the presenting symptoms, diagnostic work-up, additional therapies, and complications. Moreover, it can help us compare our data with pertinent literature. RESULTS: As evidenced by the obtained results, ISSID lesions included bacterial sphenoiditis (42.9%), fungus ball (21.4%), invasive fungal sphenoiditis (14.3%), mucocele (14.3%), and retention cysts (7.1%). In addition, headache was found to be the major complaint, followed by nasal symptoms. Diplopia, and signs and symptoms of the involvement of other cranial nerves were less frequent. All patients underwent endoscopic transnasal sphenoidectomy. The overall survival rate was reported as 92.9% (13/14), and all patients with cranial nerve palsies demonstrated complete clinical remission. CONCLUSION: Both the review of related literature and our clinical cases were indicative of the dangerous consequences of ISSIDs. Their varied and unspecific presentation and the limited reliability of nasal endoscopy required the cooperation of ENT (ear, nose, and throat) team with other specialists to make an accurate diagnosis and decide on the most appropriate therapeutic choices. If the signs of intracranial complications were detected, surgery should be promptly performed to maximize the chances of recovery.

RESUMEN

The need for patient-centered care has become a focal point of healthcare improvement initiatives. Shared decision making-in which patients and clinicians communicate about various treatment options and goals and patient input is considered when making treatment decisions-has been associated with improved health and quality of life. A method of treatment evaluation allowing incorporation of patient-specific goals and perspectives is of increasing interest to healthcare providers, payers, and patients. An approach that allows incorporation of shared goal setting is possible via use of an instrument called the Goal Attainment Scale (GAS). This scale provides the structure for measuring progress toward treatment goals set through patient-clinician collaboration. The goal attainment approach has been used as a primary outcomes measure in numerous studies but not in major depressive disorder (MDD). As MDD is a complex, multidimensional disorder affecting each patient differently, the use of GAS methodology is a relevant framework for setting personalized meaningful treatment goals. Initial research into the feasibility of using the GAS in MDD (GAS-D) to measure patient-centric outcomes that may be neglected when more traditional scales are used has been encouraging. The objective of this Commentary is to provide background and rationale for implementation of the GAS-D in clinical practice.Funding Takeda Pharmaceutical Company, Ltd., and Lundbeck LLC.

RESUMEN

Isolated sphenoid sinus diseases are generally asymptomatic and relatively uncommon with the potential for serious complications. Patients with this condition should be monitored closely and treated aggressively and either diagnostic or therapeutic intent is often indicated. In the management of a complex, life-threatening condition that involves many different fields of expertise, the otolaryngologist plays a key role in orchestrating different specialists and gaining direct access to the affected area, thus taking the first and essential step towards diagnosis and therapy. Because of the superiority of computed tomography in defining the bony margins and the superior soft tissue resolution of magnetic resonance imaging, these two techniques should be used in a complementary manner in the evaluation of isolated sphenoid sinus disease in addition to mapping the lesion better and identifying intracranial and intraorbital extent. We report an unusual case of isolated rhinosinusitis of the sphenoid sinus involving the cavernous sinus, pterygoid fossae and masticatory space in an immunocompetent patient.

RESUMEN

Background/Objectives: Major depressive disorder (MDD) is a highly prevalent disorder, frequently diagnosed and treated in a primary care setting; however, little information is available about the treatment decision-making process between MDD patients and their providers. A shared decision-making and goal attainment approach to establishing and tracking progress toward treatment goals that are meaningful to individual patients is explored in this survey study. In addition, information about patient perspectives on setting treatment goals, medication selection/switching, and engaging patients with their health care professionals was also collected and evaluated. Methods: A 50-question online survey was administered to members of the PatientsLikeMe community who indicated an MDD diagnosis and a switch in antidepressant medications within the past 2 years. Follow-up interviews were also conducted with a small subset of these participants. Results: Of the 200 participants who completed the survey, 42% reported currently having goals for MDD treatment. These goals were typically in the areas of physical health (62.7%), cognitive functioning (60.2%), and social aspects of life (57.8%). A majority of survey participants (61%) believed the goal attainment approach would be helpful to set and evaluate treatment goals. Conclusions: The data provide important insights into patient perspectives on the development of formal treatment plans and goals for MDD. In addition, the data also support the use of a patient-centric approach to shared decision-making by using a goal attainment scale to establish and track progress toward treatment goals that are meaningful to MDD patients in real-world clinical practice. The results of this study can be used to inform best practices in patient-clinician communication when developing an MDD treatment plan and goals.

RESUMEN

OBJECTIVE: To evaluate long-term safety and effectiveness of continued treatment with aripiprazole once-monthly 400mg (AOM 400) in patients with schizophrenia. METHODS: Patients who completed the QUALIFY study (NCT01795547) in the AOM 400 arm were eligible for 6 additional once-monthly injections of AOM 400 during an open-label, 24-week extension (NCT01959035). Safety data were collected at each visit. Effectiveness measures included change from baseline in health-related qualify of life and functioning on the Heinrichs-Carpenter Quality of Life scale (QLS) and Clinical Global Impression - Severity (CGI-S) scale. RESULTS: Of the 88 patients enrolled, 77 (88%) completed the extension study. Most common treatment-emergent adverse events (incidence ≥2%) were weight increased (6/88, 7%), toothache (3/88, 3%) and headache (3/88, 3%). Effectiveness was maintained during the extension study, with small but continued improvements from baseline: the least squares mean (LSM) change (95% CI) from baseline to week 24 was 2.32 (-1.21 to 5.85) for the QLS total score and -0.10 (-0.26 to 0.06) for the CGI-S score. The aggregated LSM change (95% CI) from baseline of the lead-in study to week 24 of the extension study was 11.54 (7.45 to 15.64) for the QLS total score and -0.98 (-1.18 to -0.79) for the CGI-S score. CONCLUSIONS: AOM 400 was well tolerated in patients continuing AOM treatment during the extension phase of the QUALIFY study. Robust and clinically meaningful improvements in health-related quality of life and functioning were maintained, further supporting the long-term clinical benefits of AOM 400 for the treatment of patients with schizophrenia.

RESUMEN

OBJECTIVE: Long-acting injectable (LAI) antipsychotics improve treatment outcomes in patients with schizophrenia but are often reserved for only the most severely affected or nonadherent. Studies show cultural/racial differences in prescribing. This pilot study examined prescriber-patient interactions and cultural/racial differences in perceptions of LAIs among patients. METHODS: A linguist analyzed 120 prescriber-patient conversations representing selected patient cultural/racial subgroups (European American, African American, Latino American; n=40 each) to identify similarities and differences in conceptualization and attitudes toward LAIs. RESULTS: Of 35 LAI-naive patients offered LAIs, 9% (3/35) responded favorably, 46% (16/35) were neutral/passive, and 46% (16/35) had concerns or viewed LAIs as unfavorable. Among LAI-naive patients, favorable or neutral/passive responses were reported for 50% (7/14) of European Americans, 63% (10/16) of African Americans, and 40% (2/5) of Latino Americans. The majority of LAI-naive patients (57% [20/35]) accepted LAI prescriptions, including 53% (17/32) of those who initially were neutral/passive or refused treatment (European American, 42% [5/12]; African American, 53% [8/15]; Latino American, 80% [4/5]). Fifty-seven percent (68/120) of patients expressed treatment goals. Goals of positive/negative symptom control were associated with positive attitudes toward LAIs while patients with goals focused on control of anxiety and insomnia tended to have negative attitudes toward LAIs. Latino-American patients who expressed treatment goals seemed more focused on discomfort control (67% [12/18]); goals of European Americans and African Americans were more equally distributed. CONCLUSIONS: Equal numbers of LAI-naive patients had unfavorable/concerned or neutral/passive attitudes toward treatment; relatively few patients responded favorably. The limited sample size precludes cultural/racial-specific conclusions.
