From economics to health outcomes: Delving into the significance of reduced insulin prices.

The recent substantial price reductions in insulin therapy by major manufacturers prompt an examination of their impact on South Africa (SA)'s healthcare. While Eli Lilly, Novo Nordisk, and Sanofi cut prices on long-acting basal insulin, among others, significantly, these insulins are not on SA's Essential Medicines List (EML) for primary healthcare. With a high prevalence of diabetes, especially pre-diabetes, in the country, the EML's neglect of newer long-acting insulin treatments hampers effective disease management. Despite efforts by the public and private sectors, insulin therapy initiation is delayed, impacting long-term outcomes. The introduction of smart insulin pens adds a technological dimension, but concerns persist about equitable access. Urging policy-makers to re-evaluate guidelines and decolonise the EML, the article emphasises enhancing patient quality of life and reducing the disease burden.

Long-acting HIV Treatments: Study Design, Logistics, and Access.

New long-acting HIV treatment products have the potential to change the HIV epidemic in the United States and globally. Phase 3 clinical trials of HIV treatments tend to underrepresent populations bearing a disproportionate burden of the HIV epidemic-including women, racial minorities, trans and gender-diverse people, older adults, the unhoused, people who inject drugs, those in rural areas, individuals with mental illness, and other marginalized groups. These populations commonly face significant challenges in adhering to daily HIV treatment regimens. Conducting clinical trials of long-acting treatment targeting specific unmet medical needs of these populations can improve understanding of optimal care approaches, broaden the indication for use of long-acting products, and inform treatment guidelines, all of which can influence reimbursement and access policies. Innovative trial designs and programmatic implementation can improve inclusivity for long-acting therapy. This article summarizes discussions of a multistakeholder workshop on study designs for long-acting HIV treatments.

An injectable, nanostructured implant for the delivery of adenosine triphosphate: towards long-acting formulations of small, hydrophilic drugs.

While long-acting injectable treatments are gaining increasing interest in managing chronic diseases, the available drug delivery systems almost exclusively rely on hydrophobic matrixes, limiting their application to either hydrophobic drugs or large and hydrophilic molecules such as peptides. To address the technological lock for long-acting delivery systems tailored to small, hydrophilic drugs such as anticancer and antiviral nucleoside/nucleotide analogues, we have synthesized and characterized an original approach with a multi-scale structure: (i) a nucleotide (adenosine triphosphate, ATP) is first incorporated in hydrophilic chitosan-Fe(III) nanogels; (ii) these nanogels are then transferred by freeze-drying and resuspension into a water-free, hydrophobic medium containing PLGA and an organic solvent, N-methyl-2-pyrrolidone. We show that this specific association allows an injectable and homogeneous dispersion, able to form in situ implants upon injection in physiological or aqueous environments. This system releases ATP in vitro without any burst effect in a two-step mechanism, first as nanogels acting as an intermediate reservoir over a week, then as free drug over several weeks. In vivo studies confirmed the potential of such nanostructured implants for sustained drug release following subcutaneous injection to mice hock, opening perspectives for sustained and targeted delivery through the lymphatic system.

Importance of the type of pharmacological treatment in patients with severe mental disorder

Introduction The use of long-acting treatments is a common clinical practice in psychiatry. No disease insight and the risk of treatment discontinuation in a significant portion of our patients, increase the demand for psychiatric emergency and hospital admissions. Treatment adherence must be facilitated, taking into account possible side effects and patient´s subjective satisfaction.Objectives-Evaluate the type of long-acting intramuscular treatment in selected patients. -Evaluate the differences in treatment satisfaction between different types of long-acting intramuscular treatments as well as frequency of psychiatric emergency and hospital admissions in the last year.MethodsWe select patients with different severe mental disorders who stay in a Medium Stay Unit, Sociosanitary Community Residence, Supervise house and Residence for the elderly in Albacete (Spain); all of them, with intramuscular neuroleptic treatment (zuclopenthixol dihydrochloride, aripiprazole long acting, palmitate paliperidone monthly, 3-monthly and 6-monthly) at least 1 year.We evaluate their sociodemographic characteristics, the satisfaction questionnaire with the treatment (TSQM-9) and the rate of psychiatric emergencies and admissions after current intramuscular treatment in last year.ResultsWe have selected 57 patients with an average age of 45.86. 78.94% with a diagnosis of schizophrenia, 12.28% with schizoaffective disorder, 5.26% bipolar disorder and 3.5% unspecified psychotic disorder.We can see in the graphics below that the longer duration of the intramuscular treatment, the greater satisfaction in all the items of the TSQM-9 questionnaire. 31% of the patients with zuclopenthixol dihydrochloride treatment, have gone to psychiatric emergencies and 28% of psychiatric admissions in the last year.18% of the patients with aripiprazole long acting, 17% with paliperidone palmitate long acting-monthly and 12% de 3-monthly have gone to psychiatric emergencies and 15%, 12% and 12% needed psychiatric admissions respectively. Patients with palmitate long acting-monthly have not emergencies or psychiatric admissions in the last year.Image:Image 2:Image 3:Conclusions- The longer long acting of the intramuscular treatments, the better patient satisfaction.- With the longer duration treatment (Palmitate paliperidone LD 6 month), we have lower psychiatric emergencies and hospital admissions.Disclosure of InterestNone Declared

Retrospective Assessment of Metabolic Syndrome and Cardiovascular Disease Risk Following Monthly and Three-Month Long-Acting Paliperidone Palmitate Treatment in Schizophrenia

IntroductionPatients with schizophrenia exhibit a higher prevalence of metabolic syndrome and cardiovascular diseases compared to the general population, resulting in increased mortality rates. The extent of this risk may vary based on the specific treatment employed.ObjectivesThis study aims to compare the risk assessments of metabolic syndrome and cardiovascular diseases in schizophrenia patients who transitioned from monthly long-acting paliperidone palmitate (PP1M) treatment to three-month long-acting paliperidone palmitate (PP3M) treatment during both treatment periods.MethodsThe research was conducted at the Psychiatry Clinic and Psychotic Disorders Outpatient Clinic of Selcuk University Faculty of Medicine. Eligible participants included patients under PP3M treatment for a minimum of 6 months and undergoing continuous monitoring in the psychotic disorders outpatient clinic. Sociodemographic and clinical data, scales, laboratory values, and measurements taken both before and during the use of PP3M and PP1M were retrieved from file records, encompassing assessments, analyses, and examinations conducted in accordance with the “Psychotic Disorders - Treatment Monitoring Protocol.” Ethical approval was obtained from the Selcuk University Ethics Committee.Results Among the 31 patients transitioning from PP1M to PP3M treatment, 15 (48.4%) were female. The mean age of the patients was 44.4±14.4 years. No statistically significant differences were observed in the mean values of clinical evaluation and side effect assessment scales, body mass index (BMI), waist-to-hip ratio, systolic blood pressure, glucose levels, cholesterol levels, prolactin levels, and thyroid-stimulating hormone (TSH) measurements between the pre- and post-treatment phases (p>0.05). However, a significant difference was identified in the mean Qrisk3 values, a cardiovascular risk index, in two distinct measurements (10-year risk score: PP1M 3.7±4.2 and PP3M 4.6±4.8, p=0.003).Conclusions Our study, designed to investigate the impact of the monthly and three-month long-acting formulations of the same antipsychotic drug on patients’ clinical status, side effects, and general health parameters, found that PP3M treatment did not significantly differ from PP1M treatment in terms of Qrisk3 values. Despite the lack of statistical significance between the parameters used in Qrisk3 calculation, the observed significant difference in Qrisk3 values is attributed to variations in age. In order to promote the widespread adoption of long-acting treatments in schizophrenia management, clinicians should engage in comprehensive comparative studies assessing both efficacy and side effects.Disclosure of InterestNone Declared

HIV. Long-acting treatment : clinical experience, limits and future perspectives

In this article, we first present the current administration criteria, the risk factors for virological failure, and our practical experience with the first long-acting injectable HIV treatment available in Switzerland (the combination of cabotegravir/rilpivirine). We then discuss the theoretical and practical potential, as illustrated by an innovative study in San Francisco, provided by administering long-acting treatment outside the current criteria. This approach could notably offer antiretroviral treatment to particularly vulnerable populations for whom oral antiretroviral therapy is sometimes challenging. Finally, we touch upon the future drug prospects of long-acting treatments under study for HIV.

Long-acting antipsychotic treatments: focus on women with schizophrenia.

Effective management of schizophrenia (SZ) requires long-term treatment with antipsychotics (APs) to prevent clinical relapse, attain remission and improve patients' personal and social functioning, and quality of life. Although APs remain the cornerstone treatment for patients with SZ, despite their potential benefits, long-acting injectable APs (LAI-APs) remain underused, most notably in women with SZ. The efficacy and tolerability of APs differ significantly between men and women, and some of these differences are more noticeable depending on the patient's age and the stage of the disorder. Although sex differences may influence treatment outcomes in SZ, their pertinence has been insufficiently addressed, especially regarding the use of LAI-APs. Some biological and social experiences, such as pregnancy, lactation, contraception and menopause, are specific to women, but these remain under-researched issues. Implications of this disorder in parenting are also of special pertinence regarding women; therefore, taking sex differences into account when treating SZ patients is now recommended, and improving personalized approaches has been proposed as a priority in the management of psychosis. In this narrative, critical review, we address some aspects specific to sex and their implications for the clinical management of women with SZ, with a special focus on the potential role of LAI-AP treatments.

Implementing long-acting injectable antiretroviral treatments in Senegal: issues, challenges and conditions for introducing them. Qualitative study with healthcare providers and patients

ABSTRACT Long-acting injectable antiretroviral therapy (LAI-ART) can offer people living with HIV (PLWH) a promising alternative to daily oral therapy. This article highlights the issues, challenges and conditions related to introducing LAI-ART into the social lives of PLWH and HIV-care practices in Senegal. Semi-structured interviews were conducted with 42 PLWH in two hospital care units in Dakar and with 13 healthcare providers and 6 peer educators. Interviews were transcribed, thematically coded and analysed using a cross-sectional approach. We found three key issues. First, simplifying living with HIV: PLWH respondents perceive LAI-ART as an opportunity to ease the burden associated with taking tablets. This enthusiasm may however be qualified by an ambivalent relationship with injections and is subject to certain conditions. Second, certain constraints linked to the medicalisation of care are to be anticipated, including the obligation to go to the hospital every two months for injections. These findings foreshadow the new management work for medical follow-up expected to fall on PLWH and caregivers. Third, the challenges of introducing LAI-ART in Senegal are to ensure adequate organisation of care and supply and sustainability of the program. These results clarify how to implement programs to introduce LAI-ART into real life in the West African context.

Real-world effectiveness of long-acting injectable antipsychotic treatments in a nationwide cohort of 12,373 patients with schizophrenia-spectrum disorders

This mirror-image study aimed to evaluate the real-life effectiveness of long-acting injectable antipsychotics (LAI) in schizophrenia. Patients with schizophrenia initiating LAIs January 2015–December 2016 were enrolled from the French National Health Data System (SNDS). Standardized mean differences (SMD > 0.1 deemed clinically significant) were calculated for psychiatric healthcare resource utilization measures assessed one year before (during oral AP treatment) and one year after LAI initiation. LAI effectiveness was analyzed overall and by age group, gender and compliance to oral AP, defined as exposure to an AP for at least 80% of the year before LAI initiation. 12,373 patients were included. LAIs were more frequently initiated in men (58.1%), young (18–34 years, 42.0%) and non-compliant (63.7%) patients. LAI initiation was effective in reducing the number and duration of psychiatric hospitalizations and psychiatric emergency department (ED) admissions in non-compliant patients (SMD = −0.19, −0.26 and −0.12, respectively), but not in compliant patients. First-generation LAIs, paliperidone and aripiprazole LAIs reduced psychiatric hospitalizations (SMD = −0.20, −0.24, −0.21, respectively) and ED admissions (SMD = −0.15, −0.13, −0.15, respectively). No differences in effectiveness were found for age or gender. In compliant patients, only aripiprazole LAI reduced the number of psychiatric hospitalizations (SMD = -0.13). Risperidone and paliperidone LAIs increased hospitalization duration (SMD = 0.15 and 0.18, respectively). The prescription of LAIs (except risperidone) should be recommended in all non-compliant patients, even in women and patients aged 35 or older. The lower frequency of administration of LAIs than of oral APs may improve compliance and hence reduce the risk of relapse. Aripiprazole LAI may represent a treatment of choice for compliant patients that should be further investigated.

81-LB: Novel Microsphere Technology Reducing Injection Site Reaction in the Development of Long-Acting GLP-1 RA Formulation

Microspheres are typically used for long-acting injectable formulation, but often the injection site reactions are reported as side effects. This can reduce patient compliance with medication despite the benefit of reducing the number of administrations. Side effects at the injection site are mostly derived from inflammatory reactions. Therefore, it is necessary to minimize inflammatory reactions for the successful development of long-acting diabetes treatments, including GLP-1 receptor agonists. The purpose of this study is to evaluate the injection site reaction in the placebo, semaglutide and tirzepatide microspheres manufactured using the conventional microsphere technology and to investigate the injection site reaction improvement in the placebo, semaglutide and tirzepatide microspheres manufactured using novel technology by adding anti-inflammatory agent, dexamethasone. Skin samples were collected from the injection site of SD rats on days 3 and 8 after the administration of microspheres with or without dexamethasone. The collected skin was stained with H&E to determine infiltration of inflammatory cells, angiogenesis, and fibrosis and was graded. When microspheres manufactured using the conventional method were subcutaneously administered to rats, infiltration of inflammatory cells and fibrous tissue formation occurred on both days 3 and 8. Higher dexamethasone content in the microsphere showed a tendency for the lesser occurrence of inflammation and greater anti-inflammatory effect in the test group. Surprisingly, improvement in the injection site reaction for microspheres containing dexamethasone was observed even at systemic dexamethasone concentrations much lower than the therapeutic level. In conclusion, this novel microsphere containing a small amount of dexamethasone shows potential for the development of a long-acting GLP-1 microsphere injectable for diabetes treatment with reduced injection site reaction.

Six-month sustained delivery of anti-VEGF from in-situ forming hydrogel in the suprachoroidal space.

Patients with wet age-related macular degeneration (AMD) require intravitreal injections of bevacizumab (Bev) or other drugs, often on a monthly basis, which is a burden on the healthcare system. Here, we developed an in-situ forming hydrogel comprised of Bev and hyaluronic acid (HA) crosslinked with poly(ethylene glycol) diacrylate for slow release of Bev after injection into the suprachoroidal space (SCS) of the eye using a microneedle. Liquid Bev formulations were cleared from SCS within 5days, even when formulated with high viscosity, unless Bev was conjugated to a high molecular-weight HA (2.6MDa), which delayed clearance until 1month. To extend release to 6months, we synthesized in-situ forming Bev-HA hydrogel initially as a low-viscosity mixture suitable for injection and flow in the SCS to cover a large area extending to the posterior pole of the eye where the macula is located in humans. Within 1h after injection, Bev and HA were crosslinked, which retained Bev for slow release as the hydrogel biodegraded. In vivo studies in the rabbit eye reported Bev release for >6months, depending on gel formulation and Bev assay. The in-situ forming Bev-HA hydrogel was well tolerated, as assessed by clinical exam, fundus imaging, histological analysis, and intraocular pressure measurement. We conclude that Bev released from an in-situ forming hydrogel may enable long-acting treatments of AMD and other posterior ocular indications.

Prospects for Long-Acting Treatments for Hepatitis C.

In 2019, more than 4 years after the widespread availability of safe, oral, curative treatments, an estimated 58 million people were living with hepatitis C virus infections (PLWHC). Additional tools may enable those not yet reached to be treated. One such tool could be long-acting parenteral formulations of HCV treatments, which may allow PLWHC to be diagnosed and cured in a single encounter. Although existing highly effective oral medications might be formulated as long-acting parenteral treatments, pharmacological, regulatory, patent, and medical challenges have to be overcome; this requires the concerted efforts of PLWHC, researchers, funding agencies, industry, the World Health Organization, and other stakeholders.

Long-Acting Treatments for Hepatitis B.

There are an estimated 257 million persons living with chronic hepatitis B for whom there are multiple potential applications of long-acting antiviral compounds. Current efforts include both injection and implant approaches to formulating derivates of existing anti-HBV compounds such as tenofovir or entecavir. Substantial progress has already occurred especially as aligned with the development of long-acting tenofovir-based medications with dual activity against human immunodeficiency virus (HIV) and hepatitis B virus (HBV). Nonetheless, substantial challenges will need to be overcome before these agents are available.

Alternative starting regimen with aripiprazole long-acting treatments, a case report

IntroductionAripiprazole long-acting treatments can significantly control symptom, improve adherence and reduce the risk of relapse compared to oral drugs. An alternative start-up guideline has recently been approved in several countries that simplifies its administration.ObjectivesTo present a case report of a patient with schizophrenia treated with alternative starting regimen of aripiprazole long-acting treatment.MethodsPresentation of a clinical case supported by a non-systematic review of literature.ResultsWe present the case of a 22-year-old patient diagnosed with schizophrenia, whose symptoms started after the birth of her son, 2 years ago. She has presented a poor clinical evolution, requiring several admissions to our inpatient service after discontinuation of her medication. The patient has taken different antipsychotics, including olanzapine and paliperidone long-acting treatment, which were suspended due to side effects (weight gain and increased prolactin levels). A switch to oral aripiprazole 20mg was made, which showed good response and tolerance. Given the persistence of irregular intake, it was decided to switch to aripiprazole long-acting treatment, applying an alternative initial regime consisting of two doses of aripiprazole long-acting treatments 400mg and one oral aripiprazole 20mg. The patient has since had no delusions or hallucinations and is living independently at home.ConclusionsThe administration of a simplified initial regime with aripiprazole long-acting treatments could improve therapeutic adherence while maintaining the same effectiveness and similar side effects.DisclosureNo significant relationships.

POSC328 Impact of Treatment Schedule on Adherence and Persistence in Osteoporosis Patients Receiving Long-Acting Therapeutics

The objective of this study was to conduct a systematic literature review (SLR) and meta-analysis on the impact of long-acting therapeutics on medication adherence, specifically to compare adherence to different schedules and between long-acting injectables and oral long-acting treatments.

Psychiatric Disorder and Its Management through Ayurveda: A Review

The prevalence of psychiatric diseases is startling. According to the National Institute of Mental Health, about 25% of adults have one or more diagnosable mental disorders. Psychiatric conditions, for the most part, respond well to treatment. Many Ayurvedic remedies are beneficial in the treatment of psychiatric problems. As a system of medicine, Ayurveda cannot overlook the importance of a patient's psychological state in diagnosing and treating illnesses. Psychic tensions are the core cause of various diseases, according to medical science. Ayurveda has a well-developed area of psychiatry, with scientifically validated methods for treating mental and physical problems related to psychological imbalance. Drugs that are synthesised for human health Synthetic medications for human brain illnesses are costly, long-acting symptomatic treatments that can have substantial and unavoidable adverse effects and low patient adherence. For various individuals' mental problems, such as Alzheimer's disease, Parkinson's disease, depression, epilepsy, schizophrenia, anxiety, and others, herbal and Ayurvedic remedies are favoured over synthetic medications. The Ayurvedic school of medicine has long been utilised to treat a variety of neurological problems. Plant products have numerous advantages, including their accessibility, low frequency of side effects, and cost-effectiveness. The established traditional methods of herbal therapies for various brain illnesses are receiving a lot of attention these days, which gives sufferers hope. Ayurvedic medicines, including either one or the other plant uniqueness or a blend of plant material, have been shown to be particularly effective in treating such diseases. Plant components prescribed for these ailments range from whole plants, roots, stems, bark, leaves, flowers, fruits, and seeds to herbs and perennial trees with a variety of plant components spanning from complete plants to portions of plants, roots, stems, bark, leaves, flowers, fruits, and seeds. It's been tried before to describe Ayurvedic treatment and the problem of synthetic pharmaceutical side effects.

Higher Rates of Persistence and Adherence in Patients with Type 2 Diabetes Initiating Once-Weekly vs Daily Injectable Glucagon-Like Peptide-1 Receptor Agonists in US Clinical Practice (STAY Study).

IntroductionReducing dosing frequency may lower treatment burden and improve persistence and adherence. This retrospective, observational study assessed persistence and adherence in patients with type 2 diabetes (T2D) initiating once-weekly or daily injectable glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in US clinical practice.MethodsThe study used data from adults (≥ 18 years) with T2D who were included in the IBM MarketScan Explorys Claims-EMR Data Set for ≥ 180 days pre-index and ≥ 365 days post-index, were GLP-1 RA and insulin naïve at first claim (index date) for once-weekly or daily injectable GLP-1 RAs (follow-up: index date + 365 days), and were propensity score (PS) matched 1:1 by baseline characteristics. Persistence, defined as the stay time, was assessed using Kaplan–Meier analysis and Cox proportional hazards models. Adherence was defined as a proportion of days covered of 0.8 or greater. To assess whether patients with more advanced disease would benefit from long-acting treatments, patients were matched to the baseline characteristics of basal insulin initiators using inverse probability of treatment weighting (IPTW).ResultsThe PS-matched cohorts (n = 784 each) had similar baseline characteristics. Once-weekly regimens were associated with significantly higher persistence than daily treatments (median stay time: 333 vs 269 days; hazard ratio 0.80 [95% confidence interval 0.71, 0.90]; p < 0.01) and with significantly higher adherence than daily regimens at 6 months and 12 months (p < 0.01 for both). Mean glycated haemoglobin reductions were greater with once-weekly than with daily treatment at 6 months (– 1.1% vs – 0.9%; p < 0.01) and 12 months (– 0.9% vs – 0.7%; p = not significant); adherent patients experienced greater reductions than those with poor adherence. Results were similar in the IPTW-matched analysis.ConclusionIn US clinical practice, once-weekly injectable treatments are associated with better persistence and adherence than daily regimens over 1 year. Once-weekly regimens may also benefit patients with more advanced T2D.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13300-021-01189-6.

Preferences of Persons With or at Risk for Hepatitis C for Long-Acting Treatments.

Whereas safe, curative treatments for hepatitis C virus (HCV) have been available since 2015, there are still 58 million infected persons worldwide, and global elimination may require new paradigms. We sought to understand the acceptability of approaches to long-acting HCV treatment. A cross-sectional, 43-question survey was administered to 1457 individuals with or at risk of HCV at 28 sites in 9 countries to assess comparative interest in a variety of long-acting strategies in comparison with oral pills. Among HCV-positive participants, 37.7% most preferred an injection, 5.6% an implant, and 6% a gastric residence device, as compared with 50.8% who stated they would most prefer taking 1-3 pills per day. When compared directly to taking pills, differences were observed in the relative preference for an injection based on age (P<.001), location (P<.001), and prior receipt of HCV treatment (P=.005) but not sex. When an implant was compared with pills, greater preference was represented by women (P=.01) and adults of younger ages (P=.01 per 5 years). Among participants without HCV, 49.5% believed that injections are stronger than pills and 34.7% preferred taking injections to pills. Among those at-risk participants who had received injectable medications in the past, 123 of 137 (89.8%) expressed willingness to receive one in the future. These data point to high acceptability of long-acting treatments, which for a substantial minority might even be preferred to pills for the treatment of HCV infection. Long-acting treatments for HCV infection might contribute to global efforts to eliminate hepatitis C.

Self- and caregiver-perceived disability, subjective well-being, quality of life and psychopathology improvement in long-acting antipsychotic treatments: a 2-year follow-up study

Objective Switching to long-acting injectable (LAI) antipsychotic maintenance treatment (AMT) represents a valuable strategy for schizophrenia. In a recovery-oriented approach, patient-reported outcomes (PROs) such as perceived disability, subjective well-being, and quality of life cannot be neglected. Methods Forty clinically stable outpatients with schizophrenia treated with oral second-generation antipsychotics were enrolled at the time of switching to the equivalent dose of LAI. 35 subjects completed this 2-year longitudinal, prospective, open-label, observational study. Patients were assessed at baseline, after 1 year, and after 2 years of LAI-AMT, using psychometric scales (Positive And Negative Syndrome Scale, PANSS; Young Mania Rating Scale, YMRS; Montgomery-Åsberg Depression Rating Scale, MADRS), PROs (Subjective Well-Being under Neuroleptics short form, SWN-K; Short Form-36 health survey, SF-36; 12-item World Health Organisation Disability Assessment Schedule, WHODAS 2.0), and caregiver-reported outcomes (12-item WHODAS 2.0). Results No psychotic relapses were observed. Psychopathology measures (PANSS total and subscales – excluding negative symptoms), mood symptoms (YMRS, MADRS), perceived disability (patient- and caregiver-administered WHODAS 2.0), subjective well-being (SWN-K), and quality of life (SF-36) showed a concomitant amelioration after 1 year, without further significant variations. Discussion Switching to LAI-AMT may decrease perceived impairment, and increase subjective well-being and quality of life in clinically stable outpatients with schizophrenia. Highlights LAI treatment may improve outcomes by reducing psychopathology levels and relapses. In a recovery-oriented approach, patient-reported outcomes cannot be neglected. LAI antipsychotics may optimise the subjective experience of treatment. Switching to LAI therapy may result in a reduction in perceived disability. There is a significant correlation between proxy- and patient-reported disability.

Assessment of hospitalizations in schizophrenia patients treated with paliperidone 1-monthly (PP1M), paliperidone 3-monthly (PP3M), aripiprazole once-monthly (AOM) and other oral antipsychotics (OAP) in clinical practice

IntroductionIt has been shown that long-acting treatments can significantly improve adherence, control symptom, and reduce the risk of relapse compared to oral drugs. However, limited real world evidence is available as to whether there are differences among the various formulations marketed.ObjectivesThis study aims to assess the impact on several prognosis variables of PP1M,PP3M,AOM and OAP drugs.MethodsAll adults (≥18 years) with schizophrenia who were initiated on PP1M, PP3M, AOM, or OAP treatment (chlorpromazine,levomepromazine,fluphenazine,haloperidol,ziprasidone,zuclopenthixol,olanzapine,quetiapine,asenapine,amisulpride, risperidone,aripiprazole,paliperidone) between 2017 and 2018 were identified in IQVIA’s database(1.8M of inhabitants from 4 Spanish areas). The rate of hospitalizations, emergency room visits, and treatment persistence was calculated using the Kaplan-Meier method. Survival curves were compared using the log-rank test (Sidak-adjustment),and Cox´s Hazard Ratios (HR) were used for the comparison between groups.ResultsData from 2275 patients were analyzed (PP1M= 387;PP3M=490;AOM=75;OAP=1323).The mean age of patients was 46.8(14.95) years, and 62.9% were male. The hospitalization rate at 12 months was significantly lower (p&lt;0.01) for PP3M (8.3%) than for AOM (21.2%), PP1M (22.1%),and OAP (29.4%).When compared with PP3M use, the HRs were 2.17 for PP1M, 2.22 for AOM,and 2.90 for OAP. Emergency room visits rate at 12 months was also significantly lower (p&lt;0. 01) for PP3M (23%) than for PP1M (36.9%), OAP (43.5%),and AOM (46.2%). Persistence rates were higher for PP3M (91%) than for any other treatment (p&lt;0.01).ConclusionsOur results outline that patients treated with PP3M experienced fewer relapses and decompensations compared to all other treatments analyzed, which might help improve the prognosis and quality of life of patients.Conflict of interestThis study was sponsored by Janssen.
