Preclinical development and characterization of a human plasma-derived high-purity factor X concentrate for therapeutic use.

INTRODUCTION: Hereditary factor X deficiency is a rare bleeding disorder, with limited treatment options. This paper describes the approach to pre-clinical development and characterization of a high-purity plasma-derived factor X concentrate, to achieve orphan drug marketing authorization for the treatment of hereditary factor X deficiency. METHODS: A chromatographic process was developed, to purify factor X from human plasma for fractionation. The product was characterized using in vitro, in vivo and ex vivo tests for potency, purity, thrombogenicity, immunogenicity, toxicity and stability. RESULTS: The production process complied with good pharmaceutical manufacturing practice. It achieved 6000-fold purification and 100-fold concentration of the factor X protein compared to human plasma. The factor X protein was 94%-96% pure. Other residual plasma proteins were well below levels in plasma, minimizing potential interference in hemostasis after therapeutic administration. Effective virus-reduction during manufacture, and the absence of thrombogenicity, toxicity and immunogenic potential were confirmed, addressing the main safety concerns historically associated with plasma-derived therapeutics. The freeze-dried product remained stable between +2°C and +30°C for at least three years. After reconstitution with water for injections, the factor X activity was maintained for at least 48 h at +18°C to +22°C. CONCLUSION: Targeted pre-clinical development of the first highly-purified concentrate to treat hereditary factor X deficiency is described. Following international guidelines for nonclinical safety testing, particular strategies were adopted for unmodified products derived from human blood plasma. This approach may also be relevant to the development of other ultra-orphan medicinal products.

iConnect CKD - virtual medical consulting: A web-based chronic kidney disease, hypertension and diabetes integrated care program.

AIMS: Chronic kidney disease patients overwhelm specialist services and can potentially be managed in the primary care (PC). Opportunistic screening of high risk (HR) patients and follow-up in PC is the most sustainable model of care. A 'virtual consultation' (VC) model instead of traditional face to face (F2F) consultations was used, aiming to assess efficacy and safety of the model. METHODS: Seventy patients were recruited from PC sites and hospital clinics and followed for 1 year. The HR patients (eGFR < 30 mL/min/1.73m2 +/- albuminuria >30 mg/mmol/L) were randomized to either VC or F2F. Patients were monitored in 6 monthly follow-up cycles by a Clinical Nurse Specialist. The specialist team provided virtual or clinical support and included a Nephrologist, Endocrinologist, Cardiologist and Renal 'Palliative' Supportive Care. RESULTS: Sixty one (87%) patients were virtually tracked or consulted with 14 (23%) being HR. At 12 months, there was no difference in outcomes between VC and F2F patients. All patients were successfully monitored. General practitioners reported a high level of satisfaction and supported the model, but found software integration challenging. Patients found the system attractive and felt well managed. Specialist consults occurred within a week, and if a second specialist opinion was required, it took another 2 weeks. CONCLUSIONS: The programme demonstrated safe, expedited and efficient follow up with a clinical and web based programme. Support from the general practitioners and patients was encouraging, despite logistical issues. Ongoing evaluation of VC services will continue and feasibility to larger networks and more chronic diseases remains the long term goal.

"We are not invited": Australian focus group results on how to improve ethnic diversity in trials.

OBJECTIVES: Lack of ethnic diversity in trials may contribute to health disparities and to inequity in health outcomes. The primary objective was to investigate the experiences and perspectives of ethnically diverse populations about how to improve ethnic diversity in trials. STUDY DESIGN AND SETTING: Qualitative data were collected via 16 focus groups with participants from 21 ethnically diverse communities in Australia. Data collection took place between August and September 2022 in community-based settings in six capital cities: Sydney, Melbourne, Perth, Adelaide, Brisbane, and Darwin, and one rural town: Bordertown (South Australia). RESULTS: One hundred and fifty-eight purposively sampled adults (aged 18-85, 49% women) participated in groups speaking Tamil, Greek, Punjabi, Italian, Mandarin, Cantonese, Karin, Vietnamese, Nepalese, and Arabic; or English-language groups (comprising Fijian, Filipino, African, and two multicultural groups). Only 10 participants had previously taken part in medical research including three in trials. There was support for medical research, including trials; however, most participants had never been invited to participate. To increase ethnic diversity in trial populations, participants recommended recruitment via partnering with communities, translating trial materials and making them culturally accessible using audiovisual ways, promoting retention by minimizing participant burden, establishing trust and rapport between participants and researchers, and sharing individual results. Participants were reluctant to join studies on taboo topics in their communities (eg, sexual health) or in which physical specimens (eg, blood) were needed. Participants said these barriers could be mitigated by communicating about the topic in more culturally cognizant and safe ways, explaining how data would be securely stored, and reinforcing the benefit of medical research to humanity. CONCLUSION: Participants recognized the principal benefits of trials and other medical research, were prepared to take part, and offered suggestions on recruitment, consent, data collection mechanisms, and retention to enable this to occur. Researchers should consider these community insights when designing and conducting trials; and government, regulators, funders, and publishers should allow for greater innovation and flexibility in their processes to enable ethnic diversity in trials to improve.

The impact of elder abuse training on subacute health providers and older adults: study protocol for a randomized control trial.

BACKGROUND: Elder abuse often goes unreported and undetected. Older people may be ashamed, fearful, or otherwise reticent to disclose abuse, and many health providers are not confident in asking about it. In the No More Shame study, we will evaluate a co-designed, multi-component intervention that aims to improve health providers' recognition, response, and referral of elder abuse. METHODS: This is a single-blinded, pragmatic, cluster randomised controlled trial. Ten subacute hospital sites (i.e. clusters) across Australia will be allocated 1:1, stratified by state to a multi-component intervention comprising a training programme for health providers, implementation of a screening tool and use of site champions, or no additional training or support. Outcomes will be collected at baseline, 4 and 9 months. Our co-primary outcomes are change in health providers' knowledge of responding to elder abuse and older people's sense of safety and quality of life. We will include all inpatients at participating sites, aged 65 + (or aged 50 + if Aboriginal or Torres Strait Islander), who are able to provide informed consent and all unit staff who provide direct care to older people; a sample size of at least 92 health providers and 612 older people will provide sufficient power for primary analyses. DISCUSSION: This will be one of the first trials in the world to evaluate a multi-component elder abuse intervention. If successful, it will provide the most robust evidence base to date for health providers to draw on to create a safe environment for reporting, response, and referral.

Australian Frontline Service Response to Elder Abuse During COVID-19: Learnings, Successes, and Preparedness for Disaster.

This study examines how service providers in Victoria, Australia, undertook early intervention and response to elder abuse during the COVID-19 pandemic in 2020-2021. This study comprised two phases: (a) interviews with 29 staff members from 23 frontline service organizations about their experience responding to the needs of vulnerable older people during COVID-19; followed by (b) a co-design workshop with 15 service providers to discuss and endorse recommendations to improve sector preparedness for early intervention and responses to elder abuse during disasters. Participants reported that the severity and frequency of elder abuse increased during the pandemic, and that remoteness of services undermined comprehensive risk assessments, especially for older people who were not proficient in English and/or current digital platforms. Service providers endorsed a range of recommendations to improve sector preparedness for responses to elder abuse during disasters, primarily to upskill providers and improve the service system and direct support for individuals.

Factors associated with adherence to treatment with olanzapine and other atypical antipsychotic medications in patients with schizophrenia.

OBJECTIVES: Poor treatment response is an important factor contributing to lack of treatment adherence. The goals of this research were to determine whether improvements in Positive and Negative Syndrome Scale (PANSS) symptom domains predict the likelihood of staying on treatment and whether differential responses to treatment with various atypical antipsychotics in specific symptom domains account for differences in discontinuation rates or treatment adherence. METHODS: We conducted a post-hoc analysis of pooled data from 5 randomized, double-blind, 24- to 28-week clinical trials in 1103 olanzapine-treated and 1090 risperidone-, quetiapine-, ziprasidone-, or aripiprazole-treated adult patients with schizophrenia. The 5 PANSS factors were tested as potential predictors of treatment adherence for all treatment groups combined. Treatment differences in the 5 PANSS factors and individual items were assessed between olanzapine and the other atypical antipsychotics combined. Secondary analyses repeated for the 21 Heinrichs Quality of Life Scale (QLS) items. RESULTS: Improvement in PANSS positive factor was the strongest predictor of treatment adherence, irrespective of medication (based on standardized scores, hazard ratio [HR], 1.58; 95% confidence interval [CI], +1.40 to +1.79; P < .001). Improvement in PANSS hostility (HR, 1.23; 95% CI, +1.11 to +1.37; P < .001) and depressive (HR, 1.15; 95% CI, +1.05 to +1.27; P = .002) factors was also a significant predictor; negative and disorganized thoughts factors were not. All QLS items had significant predictive effects. Olanzapine-treated patients showed significantly greater improvements than all other groups at week 24 on all 5 PANSS factors (P = .028 for negative; P < .001 for all others) and on 3 QLS items. CONCLUSION: Significant improvement in positive symptoms, regardless of treatment, followed by significant improvement in hostility and depressive symptoms, may best predict treatment adherence. Olanzapine-treated patients experienced significantly greater improvements in these specific symptoms than patients treated with the other atypical antipsychotics examined. These findings may further explain why olanzapine-treated patients continue treatment more often.

Proposed mechanism for rare thrombotic events after use of some Covid-19 vaccines.

Administration of AstraZeneca/Oxford and Johnson & Johnson/Janssen Covid-19 vaccines which use an adenovirus vector for DNA delivery has been associated with very rare thromboembolic complications coupled with an immune response to platelet factor 4 protein. The cause of this has not yet been identified. It is known that binding of coagulation factor proteins to the surface of some adenoviruses can protect their function. Here I propose that the thromboembolic events are caused by impairment of coagulation factor X binding to the virus capsid. The unprotected capsid then stimulates an immune response leading to platelet activation, increased thrombogenicity and formation of an antibody complex with platelet factor 4. Impaired binding of factor X may be due to an undiagnosed mutation in affected individuals. Options to test this mechanism experimentally and potential remedial actions to resolve the hazard are described. This mechanism offers a remedial route to address concerns about the safety of these vaccines, which are otherwise well-positioned to deliver global Covid-19 immunity across diverse healthcare economies.

Sex differences in clinical trials of ALRV5XR treatment of androgenetic alopecia and telogen effluvium.

Introduction: ALRV5XR treatment of androgenetic alopecia (AGA) and telogen effluvium (TE) has early evidence of regenerating a normal scalp hair phenotype in both sexes. Design: We performed two 24-week double-blinded placebo-controlled comparison trials, one in each sex, on the ALRV5XR treatment effect on hair regeneration, in AGA and TE, in 92 AGA subjects (24 also had TE). Forty-six women (age 24-64 years) and 46 men (age 22-63 years) were randomized 1:1 to either ALRV5XR or placebo regimens (one b.i.d. oral capsule and daily administration of shampoo, conditioner, and follicle serum). Evaluation: Primary outcomes: Absolute and relative changes in terminal hair (TH) density. Secondary outcomes: Response rate, changes in vellus hair (VH) density, TH/VH ratio, hair diameter, growth, and shedding rate. Results: Forty-one women (20 ALRV5XR, 21 placebo) and 36 men (17 ALRV5XR, 19 placebo) completed the trials. TH outcome was evaluable for 18 and 21 women and 11 and 11 men (ALRV5XR, placebo, respectively). Efficacy in women: 30.1 THs/cm2 (p = 0.0002) and 19.7% (p = 0.0016). Efficacy in men: 21.0 THs/cm2 (p = 0.0014) and 16.4% (p = 0.0012). 66.7% of women and 100% of men responded to ALRV5XR. TH/VH ratio for men increased 33.0% (p = 0.0033). Growth rate in women increased by 30.7 µm/24 h (p < 0.0001) and 10.0% (p < 0.0001). There were no adverse events reported. Conclusion and relevance: ALRV5XR induced significant regrowth of TH. Accelerating regrowth by reactivation of dormant telogen follicles were the dominant effects in women. Thickening of miniaturized hair and regrowth of dormant telogen follicles contributed equally to the increased TH seen in men (see Graphical Abstract).

Hair regrowth treatment efficacy and resistance in androgenetic alopecia: A systematic review and continuous Bayesian network meta-analysis.

Background: Androgenetic alopecia (AGA) affects almost half the population, and several treatments intending to regenerate a normal scalp hair phenotype are used. This is the first study comparing treatment efficacy response and resistance using standardized continuous outcomes. Objective: To systematically compare the relative efficacy of treatments used for terminal hair (TH) regrowth in women and men with AGA. Methods: A systematic literature review was conducted (from inception to August 11, 2021) to identify randomized, Placebo-controlled trials with ≥ 20 patients and reporting changes in TH density after 24 weeks. Efficacy was analyzed by sex at 12 and 24 weeks using Bayesian network meta-analysis (B-NMA) and compared to frequentist and continuous outcomes profiles. Results: The search identified 2,314 unique articles. Ninety-eight were included for full-text review, and 17 articles met the inclusion criteria for data extraction and analyses. Eligible treatments included ALRV5XR, Dutasteride 0.5 mg/day, Finasteride 1 mg/day, low-level laser comb treatment (LLLT), Minoxidil 2% and 5%, Nutrafol, and Viviscal. At 24 weeks, the B-NMA regrowth efficacy in TH/cm2 and significance (**) in women were ALRV5XR: 30.09**, LLLT: 16.62**, Minoxidil 2%: 12.13**, Minoxidil 5%: 10.82**, and Nutrafol: 7.32**, and in men; ALRV5XR: 21.03**, LLLT: 18.75**, Dutasteride: 18.37**, Viviscal: 13.23, Minoxidil 5%: 13.13**, Finasteride: 12.38, and Minoxidil 2%: 10.54. Two distinct TH regrowth response profiles were found; Continuous: ALRV5XR regrowth rates were linear in men and accelerated in women; Resistant: after 12 weeks, LLLT, Nutrafol, and Viviscal regrowth rates attenuated while Dutasteride and Finasteride plateaued; Minoxidil 2% and 5% lost some regrowth. There were no statistical differences for the same treatment between women and men. B-NMA provided more accurate, statistically relevant, and conservative results than the frequentist-NMA. Conclusion: Some TH regrowth can be expected from most AGA treatments with less variability in women than men. Responses to drug treatments were rapid, showing strong early efficacy followed by the greatest resistance effects from flatlining to loss of regrowth after 12-16 weeks. Finasteride, Minoxidil 2% and Viviscal in men were not statistically different from Placebo. LLLT appeared more efficacious than pharmaceuticals. The natural product formulation ALRV5XR showed better efficacy in all tested parameters without signs of treatment resistance (see Graphical abstract).

Comparison of metabolic changes in patients with schizophrenia during randomized treatment with intramuscular olanzapine long-acting injection versus oral olanzapine.

Metabolic changes were examined in patients with schizophrenia during treatment with either oral olanzapine or olanzapine long-acting injection (LAI). Data were collected from patients who had been stabilized on oral olanzapine (10, 15, or 20 mg/day) for ≥4 weeks and then randomized to either continued olanzapine oral treatment (n = 322) or LAI (n = 599; 150 mg/2 weeks, 405 mg/4 weeks, or 300 mg/2 weeks) for up to 24 weeks. Mean and categorical changes in metabolic parameters were analyzed. Mean changes in weight, glucose, and most lipids were generally not significantly different between treatment groups. Weight changes over time followed similar patterns and were not significantly different at endpoint between the two treatment-formulation groups. Low-density lipoprotein cholesterol decreased significantly less among olanzapine LAI-treated patients. Percentages of patients with potentially clinically significant changes in blood glucose and lipid concentrations were similar for the two treatments. Percentages of patients experiencing adverse events related to weight, diabetes, or dyslipidemia were also not significantly different between treatments. Metabolic changes in patients with schizophrenia appeared generally similar during treatment with oral olanzapine or olanzapine LAI.

Safety and efficacy of ALRV5XR in men with androgenetic alopecia: A randomised, double-blinded, placebo-controlled clinical trial.

BACKGROUND: Androgenetic alopecia (AGA) is the most common hair loss disorder seen in men. It can have an early onset but has also been associated with ageing and senescence. It often induces pronounced psychological impact. ALRV5XR, a new hair loss treatment herein evaluated, was designed to target multiple molecular pathways involved in hair growth and hair follicle stem cell biology. The main objectives of the study were the assessment of safety and efficacy profiles of ALRV5XR in men. METHODS: This 24-week, parallel randomised, placebo-controlled, double-blinded clinical trial was performed in a USA community clinic. Healthy men (age 22-65) with AGA and belonging to the Hamilton-Norwood (HN) classification I-VII and Fitzpatrick skin type (FST) I-VI, were randomly allocated in a 1:1 ratio into ALRV5XR or placebo treatment groups. Dermatologist assessment, phototrichograms, and blood samples were obtained in a blinded fashion at baseline, 12 and 24 weeks. Subjects were given a masked treatment consisting of oral capsules, shampoo, conditioner, and follicle serum, which was intended for daily use. Efficacy was assessed via absolute and per cent changes in terminal hair (TH) density, and response rates. The trial was registered with clinicaltrials.gov (NCT04450589) and is completed. FINDINGS: Forty-six subjects were enroled in the study, 23 allocated to the ALRV5XR treatment and 23 to the placebo group. Enrolment occurred from April 11 to October 23, 2018. Thirty-six subjects completed the trial (17 ALRV5XR, 19 placebo) and 11 subjects in each group were evaluable for TH outcomes. At 24 weeks, the absolute change in TH density improved by 21·0 THs/cm2 (95% CI: 9·2-32·8; p = 0·0014), and the relative density increased by 16·4% (95% CI: 7·4%-25·5%; p = 0·0012). The odds ratio for being a responder (≥ 0 change) was 87·4. TH density increased linearly and was not affected by HN, FST, ethnicity, age, or body mass index. All subjects in the ALRV5XR group responded to treatment while 81·8% of the placebo group decreased TH density. ALRV5XR induced statistically significant changes in both decrease in vellus hair (VH) density as well as in concomitant increase of the TH/VH ratio when compared to placebo. ALRV5XR was well tolerated, and no adverse events were observed. INTERPRETATION: ALRV5XR treatment resulted in clinically significant TH regrowth in men with AGA. Furthermore, it appeared to reverse the characteristic hair miniaturisation seen in this condition. When compared to results of published trials of standard therapy, ALRV5XR showed a multi-fold increase both in efficacy and in response rates. In addition, the continuance of TH regrowth from 12 to 24 weeks suggests that the normal structure and function of non-productive telogen follicles is restored and that a normal hair phenotype may be attained by extended ALRV5XR treatment.

Safety and efficacy of ALRV5XR in women with androgenetic alopecia or telogen effluvium: A randomised, double-blinded, placebo-controlled clinical trial.

BACKGROUND: Scalp hair loss (alopecia) in women is a common ageing and senescing condition. It usually presents as androgenetic alopecia (AGA) or telogen effluvium (TE) and often has pronounced psychological consequences. ALRV5XR is a novel treatment aiming to regenerate a normal hair phenotype by targeting multiple molecular pathways linked to hair growth promotion and hair follicle stem cell activation. The primary objectives of this 24-week trial were to evaluate the safety and efficacy of ALRV5XR in terminal hair (TH) regrowth in women with AGA or TE. METHODS: This randomised, double-blind, placebo-controlled trial was performed in a USA community clinic. Healthy women 18-65 years of age with AGA or TE of Ludwig classification I-II and Fitzpatrick skin type I-VI were enrolled. They were allocated in a 1:1 ratio into ALRV5XR or placebo treatment groups using a random number table. Masked dermatologist assessments, phototrichograms and blood samples were obtained at baseline, 12 and 24 weeks. Subjects were given a masked treatment regimen of oral capsules, shampoo, conditioner and follicle serum for daily administration. Main outcomes were absolute and per cent changes in TH density and response rates. The trial was registered with clinicaltrials.gov (NCT04450602) and is completed. FINDINGS: 46 subjects (23 ALRV5XR, 23 placebo) were enrolled between April 3 and October 20, 2018. Five subjects dropped out and two were non-compliant. Thirty-nine subjects completed the trial (18 ALRV5XR, 21 placebo). At 24 weeks, the absolute change in TH density improved by 30·1THs/cm2 (95% CI: 15·1-45·1; p=0·0002), and the relative density increased by 19·7% (95% CI: 8·0%-31·4%; p=0·0016). The odds ratio for being a responder (≥0 change) was 2·7. Efficacy increased 133% from week 12 to 24. Efficacy outcomes were similar in AGA and TE subjects. 66·7% of the ALRV5XR group responded by regrowing 40THs/cm2 or more hair. No adverse events were reported. INTERPRETATION: In women with AGA or TE, ALRV5XR treatment significantly increased hair regrowth without adverse events. ALRV5XR displayed a multi-fold improved efficacy and response rate when compared to published trials of standard therapy. Progressive acceleration of TH regrowth suggests regeneration of the structure and function of non-productive telogen follicles and prolonged treatment may restore a normal hair phenotype.

Genetic polymorphisms in the treatment of depression: speculations from an augmentation study using atomoxetine.

Treatment-resistant depression may be related to polymorphisms in the promoter region of the serotonin transporter gene (5-HTTLPR) or dysregulation of noradrenergic systems. To examine 5-HTTLPR genotypes and responses to treatment, adult patients (N=261) with current major depression and a symptom severity rating > or =8 on the 17-item Hamilton Depression Rating Scale (HAMD(17)) were treated for 8 weeks with open-label sertraline (100-200 mg/d). Patients remaining symptomatic (total score >4, or >1 on any item of the HAMD(17) Maier-Philipp subscale) were randomly assigned to double-blind therapy with sertraline plus either atomoxetine (40-120 mg/d) or placebo for 8 additional weeks. 5-HTTLPR genotype did not predict responses to sertraline monotherapy or discontinuation rates. Among the 138 patients remaining symptomatic after sertraline monotherapy (L/L = 21%, S/L = 50%, S/S = 29%), significantly more S/S-genotype patients achieved remission under combined sertraline/atomoxetine treatment relative to the other genotypes (S/S = 81.8%; non-S/S = 32.7%), but not under sertraline/placebo treatment (S/S = 35.7%; non-S/S = 37.7%). Minor genotypic differences were noted in adverse event profiles. In patients with poor responses to sertraline monotherapy for depression, addition of atomoxetine may improve responses to treatment of depression in S/S-genotyped patients. Although this study is speculative, it represents a pharmacologically and genotypically well-defined patient population.

Virus removal from factor IX by filtration: validation of the integrity test and effect of manufacturing process conditions.

Virus removal from a high purity factor IX, Replenine-VF, by filtration using a Planova 15N filter has been investigated. A wide range of relevant and model enveloped and non-enveloped viruses, of various sizes, were effectively removed by this procedure. Virus removal was confirmed to be effective when different batches of filter were challenged with poliovirus-1. It was confirmed that intentionally modified filters that failed the leakage test had completely lost the ability to remove virus, thus confirming that this test demonstrates gross filter failure. In the case of the more sensitive integrity test based on gold particle removal, it was found that a pre-wash step was not essential. Planova filters that had been modified by sodium hydroxide treatment to make them more permeable, and filters manufactured with varying pore-sizes over the range of 15-35 nm, were tested. The integrity test value that resulted in the removal of >4 log(10) of poliovirus-1 from the product correlated with that recommended by the filter manufacturer. Virus removal from the product was not influenced by filter load mass, flow-rate or pressure. These studies confirm the robustness of this filtration procedure and allow suitable process limits to be set for this manufacturing step.

"Is Life Worth Living?": The Role of Masculinity in the Way Men Aged Over 80 Talk About Living, Dying, and Suicide.

Men aged 85 years and over have the highest rate of suicide of any age or gender group in Australia. However, little is known about their trajectory toward suicide. The objective of this study was to understand the role of masculine norms and other life factors in the suicidality of older men. Thirty-three men aged 80 years or more took part in a semistructured focus group or interview, and/or completed a survey. Participants were asked about the issues facing older men, well-being and aging, physical health challenges, social support, mental health and help-seeking, and suicide and suicide prevention. Five themes emerged: "finding out we're not invincible," "active and tough," "strong silent types," "decision makers," and "right to die." Participants spoke about masculine norms that had influenced their lives as providers and decision makers, and now influenced how they coped with aging and their journey toward death. For some participants, suicide was seen to be a rational alternative to dependence in their final years. Suicide prevention should adopt a gendered approach and be cognizant of the influence of gender roles and masculinity in older men's lives. Further research and prevention efforts should be mindful of the impact of masculine norms of self-reliance and control on an older man's decision to end his life. Suicide prevention efforts should work to reduce stigma around the challenges of aging, maximize opportunities for control, facilitate social connection, and improve residential aged care.

Comparison of symptomatic versus functional changes in children and adolescents with ADHD during randomized, double-blind treatment with psychostimulants, atomoxetine, or placebo.

BACKGROUND: This meta-analysis was designed to determine the relationship between reduction of attention-deficit/hyperactivity disorder (ADHD) symptoms and improvement in functioning by examining short-term changes in functional and symptomatic scores in children and adolescents with ADHD. METHODS: Search of atomoxetine's clinical trial database identified four studies involving a symptomatic measure, the ADHD Rating Scale-IV-Parent Version:Investigator-administered and -scored (ADHDRS-IV-Parent:Inv), and a functional measure, the Life Participation Scale for ADHD (LPS). RESULTS: Correlation analysis revealed a moderate-to-strong association between changes in the LPS total versus ADHDRS-IV-Parent:Inv total (r: -.68). The LPS Self-control subscale showed higher correlations than the Happy/Social subscale with the symptomatic measures. Regression analysis also showed high sensitivity for functional measures to changes in symptom severity. Stratified analysis of mean changes in ADHDRS-IV-Parent:Inv scores corresponding to standardized changes in LPS functional scores indicated that a threshold reduction of 16-18 points on the ADHDRS-IV-Parent:Inv total score was needed for functional improvements to become evident. CONCLUSIONS: Subjects' symptomatic improvements appear to be reflected in improvements in their social and behavioral function as measured by the LPS. These initial findings warrant verification by replication with other outcome measures.

Atomoxetine augmentation of cholinesterase inhibitor therapy in patients with Alzheimer disease: 6-month, randomized, double-blind, placebo-controlled, parallel-trial study.

OBJECTIVES: To examine the efficacy and tolerability of atomoxetine (ATX) in improving cognitive performance of patients with Alzheimer dementia. DESIGN: A randomized, double-blind, placebo (PLA)-controlled, parallel-groups study, starting with a 5-33-day screening and evaluation period, followed by a 6-month treatment period. SETTING: Eight independent or academic outpatient clinics in the United States. PARTICIPANTS: Male or female patients, aged 55 years and older, with mild-to-moderate Alzheimer disease (Mini-Mental State Examination score between 10 and 26) at baseline. INTERVENTION: ATX (25-80 mg/day) or PLA for up to 6 months, added to ongoing cholinesterase-inhibitor therapy. MEASUREMENTS: Alzheimer Disease Assessment Scale-Cognitive Portion (ADAS-Cog, primary measure), Clinician's Interview-Based Impression of Change score at end point, Neuropsychiatric Inventory, and Alzheimer's Disease Cooperative Study Inventory-Activities of Daily Living Inventory total score, safety measures (secondary measures). RESULTS: Patients' (N = 92) scores on assessments of cognitive function, global clinical impression, and neuropsychiatric symptoms were not significantly different between treatment groups. Neither group showed significant changes from baseline on the primary measure of efficacy, the ADAS-Cog. The ATX group showed a significantly greater increase of heart rate, and the mean increase in diastolic blood pressure and decrease in weight differed significantly from the decrease in pressure and weight increase in the PLA group. No other clinically meaningful safety results were obtained. CONCLUSIONS: Addition of ATX to ongoing cholinesterase-inhibitor therapy was generally well tolerated but did not significantly improve cognitive function.

Retrospective safety analysis of atomoxetine in adult ADHD patients with or without comorbid alcohol abuse and dependence.

This post hoc analysis compared the safety of atomoxetine treatment of ADHD in adults with or without comorbid alcohol abuse/dependence. Study completion rates in patients receiving atomoxetine were comparable between heavy drinkers (60.9%) and patients with no alcohol-use disorder (71.0%) but lower in nonheavy drinkers (35.7%); however, there was no significant difference in discontinuation rates due to adverse events or lack of efficacy among these groups. Alcohol-use disorder patients, especially heavy drinkers, generally experienced the greatest frequency of treatment-emergent adverse events in both the atomoxetine and placebo groups. Vital signs and measures of hepatic function were not significantly different among the 3 drinking status groups taking atomoxetine.
