Aripiprazole Plasma Concentrations Delivered from Two 2-Month Long-Acting Injectable Formulations: An Indirect Comparison. Neuropsychiatr Dis Treat 2023; 19:1409-1416. [PMID: 37313228 PMCID: PMC10259522 DOI: 10.2147/ndt.s412357] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 05/24/2023] [Indexed: 06/15/2023] Open
Abstract
Aripiprazole 2-month ready-to-use 960 mg (Ari 2MRTU 960) is a novel long-acting injectable (LAI) formulation of aripiprazole monohydrate for administration once every 2 months, developed for the treatment of schizophrenia or maintenance monotherapy treatment of bipolar I disorder in adults (indication will vary by country). Aripiprazole lauroxil 1064 mg (AL 1064) is an LAI formulation of aripiprazole lauroxil, an aripiprazole prodrug, for administration once every 2 months, indicated for the treatment of schizophrenia in adults. This analysis provides an indirect comparison of aripiprazole plasma concentrations following multiple doses of either formulation. Clinical trial data were used to determine average steady-state aripiprazole plasma concentration (Cavg,ss), maximum aripiprazole plasma concentration (Cmax), and other pharmacokinetic parameters of either formulation following four administrations (96 patients received Ari 2MRTU 960; 28 patients received AL 1064). All pharmacokinetic parameters were considered in the context of a minimum aripiprazole therapeutic concentration (Cmin) of ≥95 ng/mL. An exposure-response analysis using data from two Phase III trials of aripiprazole once-monthly (an aripiprazole monohydrate LAI, administered monthly), showed that patients with a Cmin ≥95 ng/mL are 4.41 times less likely to relapse than patients with a Cmin <95 ng/mL. A similar analysis has not been performed for AL 1064. However, consensus guidelines for therapeutic drug monitoring recommend a range of 100-350 ng/mL for aripiprazole. Following four administrations, mean (standard deviation [SD]) Cavg,ss over the 2-month dosing interval was 263 (133) ng/mL for Ari 2MRTU 960 and 140.7 (57.3) ng/mL for AL 1064. Mean (SD) Cmax during the fourth dosing interval was 342 (157) ng/mL for Ari 2MRTU 960 and 188.8 (79.8) ng/mL for AL 1064. This indirect comparison showed that, following four administrations, Ari 2MRTU 960 and AL 1064 delivered mean aripiprazole plasma concentrations that remained above the minimum therapeutic concentration of aripiprazole over the 2-month dosing interval.

Abstract
Current guidelines for the treatment of patients with schizophrenia advocate that patients receive treatment with a long-acting injectable (LAI) antipsychotic medication if they prefer such treatment or if they have a history of poor or uncertain adherence. Available LAI formulations in the United States include first-generation antipsychotics (fluphenazine decanoate and haloperidol decanoate), risperidone/paliperidone containing products (risperidone microspheres, paliperidone palmitate, and risperidone subcutaneous), aripiprazole containing products (aripiprazole monohydrate and aripiprazole lauroxil), and olanzapine pamoate. LAI antipsychotics can address the guesswork about adherence status and patients may prefer them if they are offered this as a choice, including individuals early in their disease course. Additional approved indications in the United States for LAI antipsychotics include bipolar I disorder maintenance treatment for risperidone microspheres and aripiprazole monohydrate, and schizoaffective disorder for paliperidone palmitate once monthly. Differences and similarities among the different products are discussed, including guidance regarding optimal treatment selection. Tips are provided to enhance effective patient communication to maximize the likelihood of acceptance of this treatment modality.

Abstract
PURPOSE RBP-7000 (PERSERIS™) is a once-monthly subcutaneous extended-release risperidone formulation approved by the United States Food and Drug Administration for the treatment of schizophrenia in adults. The objective of this study was to describe the long-term impact of RBP-7000 on health-related quality of life (HRQoL), subjective well-being, treatment satisfaction and medication preference in patients with schizophrenia. PATIENTS AND METHODS HRQoL was derived from a 52-week multicentre Phase III single-arm open-label outpatient study that assessed the safety and efficacy of RBP-7000 (120 mg) in patients with schizophrenia. HRQoL was measured using the EuroQol EQ-5D-5L and Short-Form Survey SF-36 version 2; well-being using the Subjective Well-being Under Neuroleptic Treatment - Short Version (SWN-S); satisfaction using the Medication Satisfaction Questionnaire and medication preference using the Preference of Medication questionnaire. RESULTS Of 482 participants at baseline, 234 remained through the end of study (EOS; week 52). Mean HRQoL and well-being scores remained stable between baseline (EQ-5D-5L index: 0.83; SF-36v2 Physical Component Score: 50; SF-36v2 Mental Component Score: 46; total SWN-S score: 89) and EOS (EQ-5D-5L index: 0.86; SF-36v2 Physical Component Score: 49; SF-36v2 Mental Component Score: 47; total SWN-S score: 90). The proportion of participants reporting satisfaction increased between week 4 (66%) and EOS (81%), with a similar trend for the preference of RBP-7000 over previous treatment (week 4: 66%; EOS: 72%). Sensitivity analyses suggested a minor effect of dropout on characterization of change over time in patient-reported outcomes (PRO) measures. CONCLUSION Study participants attained mean HRQoL scores near that of the general US population. Over two-thirds reported high satisfaction with and preference for RBP-7000 across the study period. Additional research is needed to confirm whether these PRO translate into improved outcomes such as adherence and ultimately fewer relapses in patients with schizophrenia.

Abstract
Long-acting injectable (depot) antipsychotics are one approach in the management of individuals with schizophrenia. Since the introduction of risperidone long-acting injection in 2003, three additional second-generation antipsychotics have become available in a long-acting injectable formulation: paliperidone, olanzapine and aripiprazole. Although these different depot options can help with adherence and thus encourage better treatment outcomes, they differ in terms of specific indications, approved injection sites, needle gauge, injection volume, injection interval, requirements for oral supplementation, availability of prefilled syringes, storage needs and postinjection observation period, as well as potential drug-drug interactions and commonly encountered adverse reactions. After a review of the evidence base, guidance is offered on the appropriate selection among the long-acting injectable formulations of both first and second-generation antipsychotics.

Abstract
INTRODUCTION Delirium is an acute alteration of consciousness and cognition. Atypical antipsychotics (AA) have recently become a main part of its treatment. Studies in this population generate a series of ethical dilemmas concerning the voluntary participation of patients and their state of vulnerability since their mental faculties are, by definition, compromised. OBJECTIVE To assess whether studies with AA for the treatment of delirium obtained an approval by an ethics committee on human research (ECHR), if an informed consent (IC) was obtained, whether the IC was verbal or written, and who gave the approval to participate. METHOD Systematic review of Medline for studies of delirium where quetiapine and olanzapine were the main treatment, assessing the existence of an ECHR approval and implementation of an IC. RESULTS 11 studies were identified (6 of quetiapine and 5 of olanzapine). 5 had an ECHR approval. CONCLUSIONS Most studies examining the treatment of delirium with quetiapine or olanzapine were not subject to approval by an ECHR and most of them did not obtain an IC from the patient's legal guardian. It is essential that future studies of antipsychotics and other drugs for the treatment of delirium have the protocol approved by an ECHR and a written IC signed by the patient's legal representative, since by definition delirium is a condition that compromises superior mental processes.

Abstract
Oral aripiprazole (Abilify®) is an atypical antipsychotic agent that is approved worldwide for use in adult patients with schizophrenia. It is a quinolinone derivative that has a unique receptor binding profile as it exhibits both partial agonist activity at dopamine D(2) receptors and serotonin 5-HT(1A) receptors and antagonist activity at 5-HT(2A) receptors. In several well designed, randomized, clinical trials of 4-6 weeks duration, aripiprazole provided symptomatic control for patients with acute, relapsing schizophrenia or schizoaffective disorder. Furthermore, following 26 weeks' treatment, the time to relapse was significantly longer for patients with chronic, stabilized schizophrenia receiving aripiprazole compared with those receiving placebo. Using a variety of efficacy outcomes, aripiprazole showed a mixed response when evaluated against other antipsychotic agents in randomized clinical trials. Longer-term data showed that improvements in remission rates and response rates favoured aripiprazole over haloperidol, although, the time to failure to maintain a response was not significantly different between the treatment arms. On the other hand, improvements in positive and negative symptom scores mostly favoured olanzapine over aripiprazole, although, the time to all-cause treatment discontinuation was not significantly different between the two treatments. Several open-label, switching trials showed that aripiprazole provided continued control of symptoms in patients with schizophrenia or schizoaffective disorder. Using a variety of efficacy outcomes or quality-of-life scores, longer-term treatment generally favoured patients switched to receive aripiprazole compared with standard-of-care oral antipsychotics. Aripiprazole was generally well tolerated in patients with schizophrenia. In particular, its use seems to be associated with a lower incidence of extrapyramidal symptoms than haloperidol and fewer weight-gain issues than olanzapine. Aripiprazole also showed a favourable cardiovascular tolerability profile and its use was associated with a reduced risk of metabolic syndrome than placebo or olanzapine. As a consequence, aripiprazole may provide a more cost-effective treatment option compared with other atypical antipsychotics. In conclusion, oral aripiprazole provides an effective and well tolerated treatment alternative for the acute and long-term management of patients with schizophrenia.

Abstract
Olanzapine long acting injection has joined risperidone and paliperidone as the second generation long acting antipsychotic injection options for treatment of patients with schizophrenia. Long acting injections are important alternatives to oral medications for patients who have difficulty adhering to daily or multiple daily medication administrations, yet may be underutilized or not well understood. Patient perceptions, adherence, and preferences are important issues for health care providers to address when discussing treatment options with their patients. Reviewed here are overall patient and health care provider attitudes and perceptions regarding long acting injections and the details of olanzapine long acting injectable, the newest agent, and how it will fit in the marketplace. In addition, efficacy, safety, dosing and use data regarding this newest long acting agent are reviewed and compared to other available long acting agents.

Abstract
Olanzapine was formulated as 10% (w/w) mixture with cutina to which stearic acid was added, ranging from 10% to 90% (w/w) of the total mass to control the drug release. The molten mixtures were processed by ultrasound-assisted spray-congealing technique, obtaining solid microspheres. The drug is stable under these conditions and only a partial miscibility in the solid state was observed by DSC between the two fatty materials with two separated melting endotherms in the thermograms: this can be due to the presence of two phases inside the solid dispersion. Olanzapine is distributed into the two phases according to its partition coefficient: two phases make the system less suitable to crystallization of the drug; the loading of the drug could reach saturation with difficulty and the rate of the olanzapine release is differentiated, since the drug is released from two different carriers. Dissolution profiles suggest occurrence of a bimodal release, where each portion of the release profile is linear and the slope increases with a higher content of stearic acid in the carrier mixture, that behaves as a release promoter. Tests were also carried out with palmitic and lauric acids for comparison and also for systems in the absence of ultrasound.

Abstract
IMPORTANCE OF THE FIELD Iloperidone is a newly commercialized second-generation (atypical) antipsychotic approved for the acute treatment of schizophrenia in adults. AREAS COVERED IN THIS REVIEW the purpose of this review is to describe the pharmacokinetic profile of iloperidone and its clinical implications in the treatment of schizophrenia. Background information is also provided regarding chemistry, pharmacodynamics, clinical efficacy and safety data, and regulatory affairs. WHAT THE READER WILL GAIN the reader will have an understanding of the pharmacokinetics and overall metabolism of iloperidone within the context of efficacy and safety. TAKE HOME MESSAGE time to peak plasma concentration occurs in 2 - 4 h but elimination half-life is 18 h for extensive CYP2D6 metabolizers and 33 h for poor CYP2D6 metabolizers, suggesting that once or twice daily dosing would be feasible. Dizziness and/or postural hypotension are the limiting factors for how fast iloperidone can be titrated, and is explained by iloperidone and its metabolites' norepinephrine alpha 1 antagonism. Efficacy of iloperidone appears similar to that for ziprasidone and haloperidol, but iloperidone may be inferior in efficacy to risperidone. Iloperidone can prolong the ECG QT interval. The tolerability profile of iloperidone is noteworthy in terms of modest weight gain, no medically important changes in lipid and glucose, little in the way of prolactin elevation, and an absence of extrapyramidal adverse effects, including akathisia.

Abstract
OBJECTIVE Adding another antipsychotic to a treatment regimen was previously used in evaluating the medication's efficacy. Supplementation of depot antipsychotics with oral antipsychotics is particularly meaningful because depot formulations are typically chosen for patients struggling with adherence to oral antipsychotics. This post-hoc analysis assessed supplementation of olanzapine long-acting injection (olanzapine-LAI) with oral olanzapine. SUBJECTS AND METHODS We used 12 months of data from an open-label, single-arm extension study of patients with schizophrenia or schizoaffective disorder (N=931) treated with olanzapine-LAI. The prevalence, duration, time to first supplementation, and best predictors of oral supplementation were assessed. RESULTS Oral supplementation occurred in 21% of patients for a median of 31 days with mean modal dose of 10.8 mg/day. Mean time to first supplementation was shorter for patients who were at least moderately ill at baseline compared to less ill patients (47 vs. 97 days, p<0.001). Best predictors of oral supplementation included a more severe illness profile at baseline, lower olanzapine-LAI dose prior to oral supplementation, supervised living arrangements, and being African-American. CONCLUSION Supplementation of olanzapine-LAI appears to be infrequent, of relatively short duration, and reserved for more severely ill patients who may require a targeted rescue medication due to signs of impending relapse.
