[PMID: 38733772 DOI: 10.1016/j.biopha.2024.116728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 05/01/2024] [Accepted: 05/06/2024] [Indexed: 05/13/2024] Open
Abstract
Patients' expectations and beliefs regarding the potential benefits and harms of medical interventions may induce placebo and nocebo effects, and affect the response to pain therapies. In a randomized clinical trial, we examined the effect of placebo and nocebo expectations on pain relief and adverse events (AEs) in association with a topical treatment among 65 cancer survivors experiencing chronic musculoskeletal pain. Participants received either a 1% camphor-based topical pain patch or a placebo treatment for 14 days. We measured pain severity with the worst pain item of the Brief Pain Inventory (BPI) at baseline and 14 days and treatment expectations at baseline with validated expectation questionnaires. We found that high vs. low nocebo expectations decreased pain severity improvements by 2.5 points (95% confidence interval [CI] -3.8 to -1.2; p<0.001) on a 0-10 numeric rating scale of the BPI and pain response rate by 42.7% (95% CI 0.2-0.6; p<0.001) at day 14, irrespective of placebo expectation status or treatment arms. Patients with high vs. low nocebo expectations in the true arm reported 22.4% more unwanted AEs. High nocebo expectations were associated with increased AEs by 39.5% (odds ratio: 12.0, 95% CI 1.2, 145.5; p=0.029) and decreased pain response in the true arm vs. placebo. Our study demonstrated that nocebo expectations, rather than placebo expectations, elevate the risk of AEs and compromise the effect of topical pain interventions. The findings raise the possibility that nocebo expectations may worsen somatic symptoms through heightening central pain amplification and should be further investigated.

Abstract
BACKGROUND Despite the established efficacy of glycopyrronium bromide in reducing drooling among children with neurodevelopmental disabilities, evidence on its impact on the daily lives of children and parents and effectiveness in a real-world setting are scarce, especially among long-term users. This study explored timing and duration of glycopyrronium treatment, effect and impact on daily life, and occurrence of side effects to inform clinical practice. METHODS This was a retrospective cohort study at a national referral centre for drooling, including 61 children with nonprogressive neurodevelopmental disabilities, treated with glycopyrronium for anterior and/or posterior drooling between 2011 and 2021. Data were obtained from medical records and supplemented by structured telephone interviews with parents. RESULTS Anterior drooling severity decreased in 82% of the included children. Changes in the impact of drooling on burden of care, social interaction, and self-esteem were reported in 55%, 31%, and 36%, respectively. Side effects were noted for 71% of cases, yet only 36% of parents deemed these as outweighing the positive impact of treatment. A substantial majority (77%) of the included children were long-term users (≥6 months). Among these, 38% of parents reported decreasing effectiveness and 27% noticed more prominent side effects over time. CONCLUSIONS Glycopyrronium demonstrated potential in mitigating the impact of drooling on daily life, although variations were observed in the specific aspects and extent of improvement. The real-world context of our study provides important insights for refining clinical practices, emphasizing the need for balanced consideration of treatment benefits and potential side effects to facilitate shared decision-making.

Abstract
Some patients with COVID-19 develop symptoms after the acute infection, known as 'Long COVID'. We examined whether or not confirmation of COVID-19 infection status could act as a nocebo, using data from questionnaires distributed to the Avon Longitudinal Study of Parents and Children cohort. We examined associations between confirmation of COVID-19 infection status (confirmed by a positive test vs unconfirmed) and reporting of Long COVID symptoms. We explored the roles of sex and anxiety as potential moderators. There was no clear evidence of a strong association between confirmation of COVID-19 infection status and the Long COVID composite score, physical or psychological symptoms or duration of symptoms. There was no clear evidence of moderation by sex or anxiety. We therefore found no evidence of a nocebo effect. Our data suggest that this psychological mechanism does not play a role in the medical symptomatology experienced by patients with Long COVID.

Abstract
The aim of this study was to describe the opinions of patients undergoing treatment with originator biologics and medical consultants managing their conditions and identify the barriers and enablers to transitioning from originator biologics to equivalent biosimilars. This study was undertaken prior to biosimilar switching at a large teaching hospital in the United Kingdom. Five gastroenterology, rheumatology, and dermatology consultants were interviewed. Two focus groups were conducted with patients prescribed infliximab (n = 2) and etanercept originators (n = 7). Four main themes emerged, as follows: (1) 'Benefit to the NHS'; (2) 'Evidence for efficacy and safety'; (3) 'Team roles'; and (4) 'Effective communication during switching', with sub-themes such as (4a) 'What patients want to know' and (4b) 'How it should be communicated'. Recognition of the ability to save NHS money was an enabler for both patients and consultants, with patients wanting to be reassured that the money saved would be used to benefit other patients. Consultants did not always believe that biosimilars had similar efficacy as the originators or that the manufacturing standards were the same. Effective interventions to address these concerns are required. Offering patients the opportunity to revert back to their originator if necessary was seen as an enabler, as was the provision of readily available mechanisms for reporting suspected adverse events resulting from switching. The role of pharmacy in the process of switching from originator biologics to biosimilars can range from educating consultants regarding the safety and efficacy of biosimilars, explaining the rationale for switching patients, and providing a route for reporting adverse events.

Abstract
BACKGROUND The nocebo effect is often disregarded in medical practice and is certainly much less known than the placebo effect, although, in reality, both can influence therapeutic decision making and the quality of life of patients. However, the nocebo effect raises a number of issues not only of a practical nature related to clinical activity but also ethical dilemmas related to the observance of the patient's autonomy, nonmaleficence, or informed consent and the information on which it is based. AREAS OF UNCERTAINTY The ethical dilemmas raised by the nocebo effect revolve around how informed consent can be achieved, the accuracy and volume of information that is transmitted to the patient, and how to report negative side effects of therapeutic treatment. DATA SOURCES In September 2023, a narrative analysis of the literature was conducted using a combination of keywords such as nocebo, placebo, ethics, therapeutic relationship from PubMed, Scopus, Google Scholar, and so on, as well as from official documents developed at an international level (World Health Organization), for a period of 10 years (2012-2021). RESULTS Analyzing the articles that remarked upon the significant impact of ethics in nocebo research or in the therapeutic relationship, we can state that the existence of several relevant issues of interest have been detected regarding the ethical use of nocebo and its impact in research or in clinics and thus the need for proper knowledge and management of the impact of nocebo effects. The ethical paradox of obtaining informed consent with the 2 goals, first, the need for complete information and second, the preservation of the autonomy of the patient, respectively, that of "primum non-nocere" and of avoiding unnecessary harm by revealing probable adverse effects is a point of interest for numerous studies. The potential for a nocebo effect is present when we inform patients about the risks and benefits of treatment, there being a clear link between the moral and ethical duty to inform patients and the need to avoid situations that increase the nocebo impact on how the disease or the adverse effects of the treatment are perceived. Adapting information about the side effects of medicines should focus on ensuring a balance between transparency and caution, especially in patients with a high potential for nocebo effect. CONCLUSIONS The nocebo effect had for a long time been unknown or denied, although it can interfere with the results of the treatment used. As the nocebo phenomenon becomes increasingly known in medical practice, the clinical and ethical implications are identified by medical staff, and nocebo's adverse responses are no longer ignored.

Abstract
OBJECTIVES To assess the usefulness and onset of nocebo effects after switching from the original etanercept (ETN) to a biosimilar (BS) in routine clinical practice at rheumatology clinics in Japan (13 sites). METHODS A total of 165 patients (87.0% women, age = 57.88 ± 15.07 years, and disease duration = 10.32 ± 7.71 years), whose low disease activity was maintained with the original ETN for ≥12 weeks, and who agreed to switch treatment to its BS, were included. The end-points were disease activity score 28 (DAS28)-C-reactive protein and DAS28-erythrocyte sedimentation rate. RESULTS No significant difference was observed between the changes in DAS28-C-reactive protein and DAS28-erythrocyte sedimentation rate >12 weeks before switching and >12 weeks after switching (P = 0.132 and 0.334, respectively). The treatment continuation rate during the 52 weeks after switching to BS was 97.3%. During this period, BS was discontinued in only four patients, and no nocebo effects were suspected in these four patients. CONCLUSION Switching from ETN to BS was effective even in routine clinical practice at rheumatology clinics in Japan, and no nocebo effects were observed. Sufficient explanations to patients by rheumatologists and the additional payment for drug costs between patients at hospital visits effectively improved the continuation rate without any nocebo effect.

Abstract
Biological therapies have transformed high-burden treatments. As the patent and exclusivity period for biological medicines draws to a close, there is a possibility for the development and authorization of biosimilars. These products boast comparable levels of safety, quality, and effectiveness to their precursor reference products. Biosimilars, although similar to reference products, are not identical copies and should not be considered generic substitutes for the original. Their development and evaluation involve a rigorous step-by-step process that includes analytical, functional, and nonclinical evaluations and clinical trials. Clinical studies conducted for biosimilars aim to establish similar efficacy, safety, and immunogenicity, rather than demonstrating a clinical benefit, as with the reference product. However, although the current knowledge regarding biosimilars has significantly increased, several controversies and misconceptions still exist regarding their immunogenicity, extrapolation, interchangeability, substitution, and nomenclature. The development of biosimilars stimulates market competition, contributes toward healthcare sustainability, and allows for greater patient access. However, maximizing the benefits of biosimilars requires cooperation between regulators and developers to ensure that patients can benefit quickly from access to these new therapeutic alternatives while maintaining high standards of quality, safety, and efficacy. Recognizing the inherent complexities of comprehending biosimilars fully, it is essential to focus on realistic approaches, such as fostering open communication between healthcare providers and patients, encouraging informed decision-making, and minimizing risks. This review addresses the regulatory and manufacturing requirements for biosimilars and provides clinicians with relevant insights for informed prescribing.

Abstract
BACKGROUND The non-interventional PROPER study generated real-world evidence on clinical outcomes following transition in routine practice from reference adalimumab to the EMA-approved SB5 biosimilar adalimumab in patients with immune-mediated inflammatory disease. METHODS Adults with rheumatoid arthritis (RA), axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), Crohn's disease (CD), or ulcerative colitis (UC) were enrolled at 63 sites across Europe. Eligible patients received ≥ 16 weeks of routine treatment with reference adalimumab before transitioning to SB5, and were followed for 48 weeks post-transition. The primary objective was to evaluate candidate predictors (clinically relevant baseline variables with incidence ≥ 15% by indication cohort) associated with persistence on SB5 at 48 weeks post-initiation. Key primary outcome measures were persistence on SB5 (estimated by Kaplan-Meier methodology) and clinical characteristics and disease activity scores at the time of transition to SB5 treatment (baseline). RESULTS A total of 955 eligible patients were enrolled (RA, n = 207; axSpA, n = 127; PsA, n = 162; CD, n = 447; UC, n = 12), of whom 932 (97.6%) completed follow-up and 722 (75.6%) were still receiving SB5 at week 48. Kaplan-Meier estimates (95% confidence interval, CI) of persistence on SB5 at week 48 for RA, axSpA, PsA, and CD were 0.86 (0.80-0.90), 0.80 (0.71-0.86), 0.81 (0.74-0.86), and 0.72 (0.67-0.76), respectively. The single candidate predictor associated with probability of SB5 discontinuation before week 48 was female sex [RA, axSpA, and CD cohorts; HR (95% CI): 3.53 (1.07-11.67), 2.38 (1.11-5.14), and 2.21 (1.54-3.18), respectively]. Disease activity scores remained largely unchanged throughout the study, with proportions by cohort in remission at baseline versus week 48 being 59.2% versus 57.2%, 81.0% versus 78.0%, 94.7% versus 93.7%, and 84.0% versus 85.1% for patients with RA, axSpA, PsA, and CD, respectively. Similarly, the SB5 dosing regimen remained unchanged for the majority of patients from baseline to week 48, the most common regimen being 40 mg every 2 weeks. In total, 232 patients (24.3%) reported at least one adverse drug reaction, and most events were mild; eight patients (3.9%) in the RA cohort experienced nine serious adverse events (SAEs; two possibly related to SB5); eight patients (4.9%) in the PsA cohort experienced nine SAEs (one possibly related to SB5); 22 patients (4.9%) in the CD cohort experienced 27 SAEs (four possibly related to SB5); and no SAEs were observed in the UC cohort. CONCLUSIONS With the exception of female sex in RA, axSpA, and CD, none of the candidate predictors were associated with SB5 discontinuation. Persistence on SB5 was high, treatment effectiveness was maintained, and no safety signals were detected. TRIAL REGISTRATION This trial is registered with ClinicalTrials.gov: NCT04089514.

Many candidate drugs for dry eye disease (DED) have been assessed over the years in pursuit of demonstrating efficacy in both signs and symptoms. However, patients with DED have very limited treatment options for management of both signs and symptoms of DED. There are several potential reasons behind this including the placebo or vehicle response, which is a frequent issue observed in DED trials. A high magnitude of vehicle response interferes with the estimation of a drug's treatment effect and may lead to failure of a clinical trial. To address these concerns, Tear Film and Ocular Surface Society International Dry Eye Workshop II taskforce has recommended a few study design strategies to minimize vehicle response observed in DED trials. This review briefly describes the factors that lead to placebo/vehicle response in DED trials and focuses on the aspects of clinical trial design that can be improved to mitigate vehicle response. In addition, it presents the observations from a recent ECF843 phase 2b study, wherein the study design approach consisted of a vehicle run-in phase, withdrawal phase, and masked treatment transition, and led to consistent data for DED signs and symptoms and reduced vehicle response post randomization.

JOURNAL OF EDUCATION AND HEALTH PROMOTION 2023; 12:257. [PMID: 37727431 PMCID: PMC10506782 DOI: 10.4103/jehp.jehp_221_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Accepted: 04/03/2023] [Indexed: 09/21/2023]
Abstract
BACKGROUND Psychological distress and perceived stress may complicate the clinical presentation, course, and treatment of patients with functional gastrointestinal disorders. The correlation between psychological distress, perceived stress, and the nocebo effect (multifood adverse reaction) in patients with irritable bowel syndrome (IBS) was the main aim of the present study. MATERIALS AND METHODS In this cross-sectional correlation study, data on 4,763 Iranian adults, 748 of whom by purposive sampling were patients with IBS (65.1% female), working in 50 different health centers affiliated to the Isfahan University of Medical Sciences across Isfahan province were examined. For assessing dietary intake, a 106-item self-administered Dish-based Semi-Quantitative Food Frequency Questionnaire that was specifically designed and validated for Iranian adults was used. General Heath Questionnaire 12 and Stressful Life event Questionnaire were used to assess psychological distress and perceived stress. By using a modified Persian version of the Rome III questionnaire, IBS was assessed. Based on researcher-made definition of nocebo effect (multiitem food intolerance), 164 people had the nocebo phenomenon in IBS group. RESULTS Age, sex, education, marital status, antidepressant use, and specifically chronic underlying disease (odds ratio [OR]: 3.54, 95% confidence interval [CI]: 1.73-7.23) of general characteristics had a significant correlation (P <.05) with presenting nocebo responses in IBS patients. Psychological distress (OR: 1.415; 95% CI: 0.992-2.020; P = 0.056) had a significant correlation with nocebo effect and did not find significant correlation with perceived stress (OR: 0.999; 95% CI: 0.990-1.008; P = 0.865). Data were analyzed by Chi-square test, analysis of variance, and OR. CONCLUSION The present study showed that psychological distress with chronic underlying disease and antidepressant use are important elements in presenting multifood adverse reactions that we named here as the nocebo effect in IBS patients. Reducing psychological distress and managing chronic underlying diseases appear to be an effective factor in reducing the nocebo phenomenon in IBS patients. For managing the nocebo responses in IBS patients, these findings may help clinicians to improve their interventions. Further studies are required to confirm these findings.

Abstract
BACKGROUND Few data are available on subjective disease control and perception of adverse events (AEs) during switching from original anti-TNF agents to biosimilars. RESEARCH DESIGN AND METHODS Hungarian patients with inflammatory bowel disease were interviewed after a mandatory non-medical switch from an infliximab (IFX) originator to a biosimilar GP1111 or from an adalimumab (ADA) originator to a biosimilar GP2017. Drug choice was based on patient's and physician's decision. Subjective efficacy was measured using a 10-point scale, and AEs were assessed. Difference in efficacy before and after the switch was compared within and between the drugs. RESULTS Seventy-three ADA and 106 IFX switching patients were interviewed. Subjective efficacy of IFX biosimilar was rated lower compared to IFX originator (8.72 ± 1.68 vs. 7.77 ± 2.34; p = 0.001). The ADA biosimilar was rated higher than its originator (9.02 ± 1.61 vs. 8.42 ± 1.93; p = 0.017). Patients receiving ADA biosimilar were more satisfied with the new treatment compared to IFX (p = 0.032). The incidence of new AEs was 85% in the ADA and 55% in the IFX group (1.79 vs. 0.93 AEs per patient, respectively, p < 0.001). CONCLUSION Subjective efficacy of switching to a biosimilar was proven in case of ADA, while reduced efficacy was experienced with IFX biosimilar. Perception of AEs was high and varied between biosimilars.

Abstract
Long-term control of SARS-CoV-2 requires effective vaccination strategies. This has been challenged by public mistrust and the spread of misinformation regarding vaccine safety. Better understanding and communication of the longer-term and comparative experiences of individuals in the general population following vaccination are required. In this population-based longitudinal study, we included 575 adults, randomly selected from all individuals presenting to a Swiss reference vaccination center, for receipt of BNT162b2, mRNA1273, or JNJ-78436735. We assessed the prevalence, onset, duration, and severity of self-reported adverse effects over 12 weeks following vaccination. We additionally evaluated participants' perceptions of vaccines, trust in public health authorities and pharmaceutical companies, and compliance with public health measures. Most participants reported at least one adverse effect within 12 weeks following vaccination. Adverse effects were mostly mild or moderate, resolved within three days, and rarely resulted in anaphylaxis or hospitalizations. Female sex, younger age, higher education, and receipt of mRNA-1273 were associated with reporting adverse effects. Compared to JNJ-78436735 recipients, a higher proportion of mRNA vaccine recipients agreed that vaccination is important, and trusted public health authorities. Our findings provide real-world estimates of the prevalence of adverse effects following SARS-CoV-2 vaccination and highlight the importance of transparent communication to ensure the success of current or future vaccination campaigns.

Abstract
Biologics have changed the landscape for the management of many debilitating chronic diseases but account for a significant expenditure of medications globally. Fortunately, advances in technology paved the way for the introduction of biosimilars, which are highly similar to the originator biologics. In the quest to reduce the budget impact of biologics, organizations have begun to adopt biosimilars. Institutions evaluating biosimilars for inclusion in the hospital formulary must make informed formulary decisions by conducting a thorough review of key elements for evaluation of biosimilars and address the multidimensional aspects during the selection process of different biosimilar products. Therefore, we aim to present an institutional guide of these elements to inform formulary decisions. These key elements include biosimilar evaluation for formulary addition; regulatory approval; substitution, interchangeability, and switching; extrapolation; product characteristics, manufacturing, and supply chain issues; pharmacoeconomic evaluations; traceability, nomenclature, and coding; education; and pharmacovigilance.

Abstract
The approval and adoption of biosimilar products are essential to contain increasing healthcare costs and provide more affordable choices for patients. Despite steady progress in the number of the US Food and Drug Administration (FDA) biosimilar approvals over the years, biosimilar adoption in the United States has been slow and gradual, largely driven by payers rather than clinicians. In order to better understand the barriers to biosimilar adoption in the clinic, the University of Maryland Center of Excellence in Regulatory Science and Innovation (M-CERSI) and the FDA jointly hosted a virtual workshop on April 13, 2022, titled "Biosimilars: A Decade of Experience and Future Directions - Strategies for Improving Biosimilar Adoption and the Potential Role of Clinical Pharmacology." This summary documents the experiences of four leading academic clinicians with specialties in oncology, rheumatology, gastroenterology, and endocrinology and their perspectives on how to increase biosimilar adoption, including the role of clinical pharmacology. Besides systemic changes in pricing and reimbursement, there is a need for additional education of a broad range of providers, including advanced care practitioners, and patients themselves. Educational efforts highlighting the rigor of the studies that support the approval of biosimilars-including the clinical pharmacology studies-and the benefits of biosimilars, can play a major role in improving biosimilar acceptance.

Abstract
The neurodegenerative disease field has enjoyed extremely limited success in the development of effective therapeutics. One potential reason is the lack of disease models that yield accurate predictions and optimal therapeutic targets. Standard clinical trials have pre-determined a single treatment modality, which may be unrelated to the primary drivers of neurodegeneration. Recent proof-of-concept clinical trials using a precision medicine approach suggest a new model of Alzheimer's disease (AD) as a chronic innate encephalitis that creates a network insufficiency. Identifying and addressing the multiple potential contributors to cognitive decline for each patient may represent a more effective strategy. Here we review the rationale for a precision medicine approach in prevention and treatment of cognitive decline associated with AD. Results and implications from recent proof-of-concept clinical trials are presented. Randomized controlled trials, with much larger patient numbers, are likely to be significant to establishing precision medicine protocols as a standard of care for prevention and treatment of cognitive decline. Furthermore, combining this approach with the pharmaceutical approach offers the potential for enhanced outcomes. However, incorporating precision medicine approaches into everyday evaluation and care, as well as future clinical trials, would require fundamental changes in trial design, IRB considerations, funding considerations, laboratory evaluation, personalized treatment plans, treatment teams, and ultimately in reimbursement guidelines. Nonetheless, precision medicine approaches to AD, based on a novel model of AD pathophysiology, offer promise that has not been realized to date with monotherapeutic approaches.

Abstract
BACKGROUND There is a growing number of trials examining the effectiveness of pharmacotherapies for obesity, however, little is known about placebo and nocebo effect in these trials. Hence, we sought to examine the effect of placebo in obesity trials, to better understand the potential factors affecting clinical endpoints in them. METHODS Medline, Embase, and Cochrane CENTRAL were searched for articles examining weight-loss RCTs examining patients with overweight or obesity in placebo-controlled arms from inception till 25 June 2022. This paper was registered online with PROSPERO (CRD42022302482). A single arm meta-analysis of proportions was used to estimate the primary outcomes, ≥5%, ≥10%, and ≥15% total weight loss - and the adverse effects that patients experienced during the trial. A meta-analysis of means was used to estimate the pooled mean differences of the secondary outcomes including, body weight measurements, lipid levels, glycemic indices, and blood pressure over time. FINDINGS A total of 63 papers involving 20,454 patients and 69 trials were included. The proportion of patients that had ≥5%, ≥10%, and ≥15% weight loss was 20·4% (CI:16·1% to 25·0%), 8·3% (CI:6·1% to 10·9%), and 6·2% (CI:3·8% to 9·7%), respectively. Analysis by duration of trials showed stepwise increase in proportion of patients with ≥5% and ≥10% weight loss with increasing duration of study. Analysis of secondary outcomes found modest improvement in all analyses. The pooled average rate of overall AEs, serious AEs, and discontinuation was 73·7% (CI:68·0% to 79·0%), 3·4% (CI:2·4% to 4·5%), and 5·2% (CI:4·0% to 6·5%), respectively. In psychiatric complications, the pooled rates of anxiety and depression were 2·7% (CI:1·8% to 3·7%) and 2·5 (CI:1·7% to 3·3%). INTERPRETATION Our meta-analysis of placebo-treated participants in weight-loss RCTs indicate a significant placebo and nocebo effect. These findings are important to quantify their effect and may inform the design of future RCTs. FUNDING This research did not receive additional support from organizations beyond the authors' academic institutions.

Safety of Four COVID-19 Vaccines across Primary Doses 1, 2, 3 and Booster: A Prospective Cohort Study of Australian Community Pharmacy Vaccinations. Vaccines (Basel) 2022; 10:vaccines10122017. [PMID: 36560426 PMCID: PMC9786585 DOI: 10.3390/vaccines10122017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/23/2022] [Accepted: 11/24/2022] [Indexed: 11/29/2022] Open
Abstract
Four COVID-19 vaccines are approved for use in Australia: Pfizer-BioNTech BNT162b2 (Comirnaty), AstraZeneca ChAdOx1 (Vaxzevria), Moderna mRNA-1273 (Spikevax) and Novavax NVX-CoV2373 (Nuvaxovid). We sought to examine adverse events following immunisation (AEFI) at days 3 and 42 after primary doses 1, 2, 3 and booster. We conducted active vaccine safety surveillance from 130 community pharmacies in Australia integrated with AusVaxSafety, between August 2021-April 2022. Main outcomes: AEFI at 0-3 days post-vaccination; medical review/advice at 3 days and 42 days post-vaccination; SARS-CoV-2 breakthrough infection by day 42. Of 110,024 completed day 3 surveys (43.6% response rate), 50,367 (45.8%) reported any AEFI (highest proportions: Pfizer 42%, primary dose 3; AstraZeneca 58.3%, primary dose 1; Moderna 65.4% and Novavax 58.8%, both primary dose 2). The most common AEFI reported across all doses/vaccines were local reactions, systemic aches and fatigue/tiredness. Overall, 2172/110,024 (2.0%) and 1182/55,329 (2.1%) respondents sought medical review at days 3 and 42, respectively, and 931/42,318 (2.2%) reported breakthrough SARS-CoV-2 infection at day 42. We identified similar AEFI profiles but at lower proportions than previously reported for Pfizer, AstraZeneca, Moderna and Novavax COVID-19 vaccines. Moderna vaccine was the most reactogenic and associated with higher AEFI proportions across primary doses 2, 3, and booster.

Side-Effects following Oxford/AstraZeneca COVID-19 Vaccine in Tororo District, Eastern Uganda: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:15303. [PMID: 36430019 PMCID: PMC9690167 DOI: 10.3390/ijerph192215303] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 11/15/2022] [Accepted: 11/15/2022] [Indexed: 06/16/2023]
Abstract
Effective, safe and proven vaccines would be the most effective strategy against the COVID-19 pandemic but have faced rollout challenges partly due to fear of potential side-effects. We assessed the prevalence, profiles, and predictors of Oxford/AstraZeneca vaccine side-effects in Tororo district of Eastern Uganda. We conducted telephone interviews with 2204 participants between October 2021 and January 2022. Multivariable logistic regression was conducted to assess factors associated with Oxford/AstraZeneca vaccine side-effects using Stata version 15.0. A total of 603/2204 (27.4%) of the participants experienced one or more side-effects (local, systemic, allergic, and other side-effects). Of these, 253/603 (42.0%) experienced local side-effects, 449/603 (74.5%) experienced systemic side-effects, 11/603 (1.8%) experienced allergic reactions, and 166/603 (27.5%) experienced other side-effects. Ten participants declined to receive the second dose because of side-effects they had experienced after the first dose. Previous infection with COVID-19 (adjusted odds ratio (AOR): 4.3, 95% confidence interval (95% CI): 2.7-7.0), being female (AOR: 1.3, 95% CI: 1.1-1.6) and being a security officer (AOR: 0.4, 95% CI: 0.2-0.6) were associated with side-effects to the Oxford/AstraZeneca vaccine. We recommend campaigns to disseminate correct information about potential side-effects of the Oxford/AstraZeneca vaccine and strengthen surveillance for adverse events following vaccination.

Abstract
The placebo effect can be defined as any improvement of illnesses or reduction of subjective symptoms that result from interventions possessing no known physical effects. By contrast, the nocebo effect refers to undesirable symptoms or illnesses that follow interventions also lacking known physical effects. It may also play a role in chronic illnesses that lack objective confirmation. Both placebo and nocebo effects can be potent and must be understood by both practitioners and researchers for proper application in clinical medicine. Individual caregivers can apply these principles to modify results in the daily care of patients.

Abstract
The efficacy of statins in the primary and secondary prevention of cardiovascular disease has been proven beyond doubt. The number needed to treat to prevent one cardiovascular event is 1 in 30 over 10 years, and the number needed to treat for secondary prevention is much lower. However, a recent study demonstrated that only 68% of eligible patients are on statin therapy. Moreover, there seems to be a reluctance to escalate statin doses due to the fear of adverse effects. The adverse effects that worries patients and their physicians most frequently are those related to muscular symptoms. N-of-1 trial evidence suggests that muscular symptoms attributed to statins are often caused by the nocebo effect. This article aims to provide a structured, evidence-based approach to suspected statin-related muscle toxicity.

Abstract
Functional neurological disorder (FND) is characterized by neurological symptoms that cannot be explained by a structural neurological cause. Among the different aetiological models that have been proposed for FND, of note is the Bayesian predictive coding model, which posits that perception relies on top-down cortical predictions (priors) to infer the source of incoming sensory information. This model can also apply to non-pathological experiences, such as placebo and nocebo effects, wherein sensory information is shaped by prior expectations and learning. To date, most studies of the relationship between placebo and nocebo effects and FND have focused on the use of placebos for diagnosis and treatment of FND. Here, we propose that this relationship might go beyond diagnosis and therapy. We develop a framework in which shared cognitive, personality and neuroanatomical factors justify the consideration of a deeper link between FND and placebo and nocebo effects. This new perspective might offer guidance for clarification of the pathogenesis of FND and for the identification of potential biomarkers and therapeutic targets.

Abstract
Our aims were to provide updated information on placebo/nocebo effect and the potential use of placebo in clinical practice. This article can only provide a rough overview on the placebo and nocebo effect and is intended to serve as a starting point for the reader to go deeper into the corresponding literature. The placebo effect has been observed in multiple medical conditions, after oral administration, with manual therapies as well as with surgery and invasive procedures. The use of placebo in clinical trials is fundamental, although the ethics of its use is under discussion. The placebo may behave like a drug from the pharmacokinetic and pharmacodynamic point of view and can also be associated with adverse events (nocebo effect). Placebo can modify treatment by increasing or decreasing the effects of drugs. The factors associated with the occurrence of placebo effect are multiple, but in addition to those that depend on the placebo itself, the doctor-patient relationship would be the most important. As a result of findings that were published in the last two decades, the psycho-neurobiological basis of placebo is becoming better understood, although further studies are needed. In conclusion, the placebo effect in the clinic exhibits weak to moderate intensity. Placebo, in addition to its use in the clinical trial, should be considered another therapeutic remedy either as stand alone or in association with treatment, and could be useful in certain circumstances. The use of placebo should be regulated by the European health authorities through a guide in clinical practice that will improve patient care.

Adverse events in the placebo arm of maintenance therapy trials in advanced ovarian cancer: A systematic review and meta-analysis. Eur J Cancer 2022; 170:169-178.

Abstract
BACKGROUND Maintenance treatment is standard of care for front-line (FL) and platinum-sensitive recurrent ovarian cancer (PSROC) following response to chemotherapy. Adverse events (AEs) on maintenance therapies are common and usually attributable to investigational treatments but could also be unrelated. Randomised controlled trial (RCT) with blinded placebo design is the gold standard for determining the relative differences in efficacy and AEs between treatment arms. We performed a meta-analysis to quantify AE rates in placebo arms of RCTs to determine AEs not due to investigational agents. METHODS We performed an electronic search to identify eligible RCTs in FL and PSROC settings. Data from placebo arms were extracted and pooled using the inverse variance method to determine the risk of any AE, overall and specific grade 3 or higher (G ≥ 3) AEs, and AE-related treatment delay, reduction and discontinuation. RESULTS We identified 13 eligible RCTs (FL, N = 8; PSROC, N = 5) with 2224 patients who received placebo (FL, N = 1541; PSROC, N = 683). The majority experienced an AE of any grade (FL, 93.0%; PSROC, 95.2%). Substantial proportions experienced G ≥ 3 AEs (FL, 14.6%; PSROC, 18.2%). In the FL setting, AEs led to treatment delay in 14.4%, dose reduction in 4.1% and discontinuation in 2.6%. Findings were similar for PSROC: 8.4%, 5.5% and 2.1%, respectively. CONCLUSIONS AEs not due to investigational agents are common in ovarian cancer patients in maintenance therapy RCTs. Potential explanations include the nocebo effect, residual toxicities from previous treatment or underlying disease. Further research is required to identify better approaches to assessing AEs in this population.

Abstract
RATIONALE Psychedelic research continues to garner significant public and scientific interest with a growing number of clinical studies examining a wide range of conditions and disorders. However, expectancy effects and effective condition masking have been raised as critical limitations to the interpretability of the research. OBJECTIVE In this article, we review the many methodological challenges of conducting psychedelic clinical trials and provide recommendations for improving the rigor of future research. RESULTS Although some challenges are shared with psychotherapy and pharmacology trials more broadly, psychedelic clinical trials have to contend with several unique sources of potential bias. The subjective effects of a high-dose psychedelic are often so pronounced that it is difficult to mask participants to their treatment condition; the significant hype from positive media coverage on the clinical potential of psychedelics influences participants' expectations for treatment benefit; and participant unmasking and treatment expectations can interact in such a way that makes psychedelic therapy highly susceptible to large placebo and nocebo effects. Specific recommendations to increase the success of masking procedures and reduce the influence of participant expectancies are discussed in the context of study development, participant recruitment and selection, incomplete disclosure of the study design, choice of active placebo condition, as well as the measurement of participant expectations and masking efficacy. CONCLUSION Incorporating the recommended design elements is intended to reduce the risk of bias in psychedelic clinical trials and thereby increases the ability to discern treatment-specific effects of psychedelic therapy.

Abstract
The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, also known as "statins" are considered first-line pharmacologic therapy for reducing low-density lipoprotein cholesterol (LDL-C). They have been demonstrated efficacy in a variety of patients populations to reduce atherosclerotic cardiovascular disease (ASCVD) risk. Like any pharmacologic therapy, however, they are not without possible adverse effects that can lead to discontinuation, thus leading to a loss of benefit. The most common side effect related to statin therapy impacting compliance is musculoskeletal related, commonly referred to as statin-associated muscle systems (SAMS). While the overall incidence is relatively low, the consequences of nonadherence to statin therapy can have a negative impact on patient care. Therefore, it is important for healthcare providers to understand risk factors, how to diagnose, and how to manage this unfortunate adverse effect in order to optimize care.

Abstract
Biological therapies have revolutionized the treatment of disease across a number of therapeutic areas including retinal diseases. However, on occasion, such treatments may be relatively more expensive compared to small molecule therapies. This can restrict patient access and treatment length leading to suboptimal clinical outcomes. Several biosimilar candidates of ranibizumab and aflibercept are currently in development and the first biosimilar of ranibizumab received EMA approval in August and FDA approval in September 2021. Biosimilars are biological medicines that are highly similar to an already-approved biological medicine (reference product). The physicochemical and clinical similarity of a biosimilar is determined by a rigorous analytical and clinical program, including extensive pharmacokinetic and pharmacodynamic analysis with phase III equivalence studies where appropriate. These phase III studies are carried out in a patient population that is representative of all of the potential approved therapeutic indications of the originator product and the most sensitive for detecting potential differences between the biosimilar and the reference product. Biosimilars have been used successfully across a wide range of therapeutic areas for the past 15 years where they have achieved substantial cost savings that can be reinvested into healthcare systems without affecting the quality of patient care. The current review provides an introduction to biosimilars with the aim of preparing retinal specialists for discussing these products with their patients.

Abstract
Purpose This review aims to provide an overview of the impact of TNFis biosimilars, with marketing authorization, in patient-reported outcome measures (PROMs) scores and explore how PROMs endpoints might add value in biosimilars uptake in RA patients. Patients and Methods A comprehensive search of Medline, Scopus, Lilacs, and CINAHL databases was performed for papers published between January 2012 and December 2021. For inclusion, studies had to be prospective, published in a peer-reviewed journal, published in English or Spanish language; studies using PROMs as an outcome measure. After screening title and abstracts and assessing the remaining full texts fulfilling the inclusion criteria, 31 papers were used in this narrative review. Results PROMs were used as secondary outcomes in included studies. The most frequently employed domains to assess biosimilar efficacy include physical function, patient global assessment (PtGA), health-related quality of life (HRQoL), and fatigue. The results of randomized clinical trials uniformly showed that mean change in PROMs scores is comparable between biosimilar and reference biologic treatment groups. However, open-label and real-world studies revealed high rates of discontinuation of therapy, mainly for subjective worsening of disease activity or non-specific adverse events. Even without objective clinical evidence of inflammation, patients who are considered to have active disease (higher scores on PtGA) have higher discontinuation rates of biosimilars. The available information suggests that the nocebo effect is the most likely cause for the discontinuation of biosimilars. Conclusion There is scarce literature surrounding the impact of biosimilars in PROMs, especially in open-label studies. In real-life studies, biosimilars have a higher discontinuation rate than reference products. TNFis biosimilars treatment efficacy in RA depends on disease activity and other factors such as PtGA and fatigue. The nocebo effect is the best explanation for biosimilar’s discontinuation.

Abstract
Background Nocebo effect is prevalent among neurological diseases, resulting in low adherence and treatment outcome. We sought to examine the nocebo effect in randomized controlled trials (RCTs) in multiple system atrophy (MSA). Methods We searched RCTs in MSA from Medline since September, 2021. RCTs for drug treatment conducted in adult MSA patients with more than 5 cases in each treatment arm were included. We assessed the number of dropout due to placebo intolerance. We also did a symptomatic/disease-modifying subgroup analysis based on two different treatment purposes. The STATA software was used for statistical analysis. Overall heterogeneity was assessed using the Cochran Q and I2. Results Data were extracted from 11 RCTs fulfilling our search criteria. Of 540 placebo-treated patients, 64.2% reported at least one adverse event (AE) and 7.5% reported dropout because of AEs. The chance of dropping out because of an AE and experiencing at least one AE did not differ between placebo and active drug treatment arms. Besides, the pooled nocebo dropout rate in the symptomatic subgroup was similar to that of the disease-modifying subgroup. Conclusion In MSA RCTs, nocebo dropout rate was not at a low level among neurological disorders. Nocebo effect was an important reason of dropout because of AE in placebo and active drug treatment arms. Different treatment purposes may not influence nocebo effect.

Abstract
OBJECTIVES To evaluate the efficacy and safety of biosimilars compared with reference biological disease modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) as a part of the process of developing the 2020 update of the Japan College of Rheumatology guidelines for the management of RA. METHODS PubMed, Cochrane Library, and Japan Centra Revuo Medicina were searched for articles to conduct a systematic review (SR). The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS Twenty randomized controlled trials were included (biosimilars of infliximab, etanercept, and adalimumab). A meta-analysis revealed that the risk ratios (RRs) and 95% confidence intervals (CIs) of achieving the American College of Rheumatology 50% response (ACR50) at week 24 and serious adverse events (SAEs) for biosimilars compared with the reference bDMARDs were 1.04 (0.98-1.10) and 0.84 (0.61-1.18), respectively. The RRs of achieving ACR50 and SAEs at week 24 were respectively 0.93 (0.69-1.26) and 2.15 (0.55-8.35) in the patients who switched to biosimilars from the reference bDMARDs and 0.92 (0.76-1.12) and 1.41 (0.32-6.15) in those who continued the reference bDMARDs. CONCLUSION Biosimilars and reference bDMARDs were equally useful for the management of RA.

Abstract
A placebo is an inert substance normally used in clinical trials for comparison with an active substance. However, a placebo has been shown to have an effect on its own; commonly known as the placebo effect. A placebo is an essential component in the design of conclusive clinical trials but has itself become the focus of intense research. The placebo effect is partly the result of positive expectations of the recipient on the state of health. Conversely, a nocebo effect is when negative expectations from a substance lead to poor treatment outcomes and/or adverse events. Randomized controlled trials in functional urology have demonstrated the importance of the placebo and nocebo effects across different diseases such as overactive bladder, urinary incontinence, lower urinary tract symptoms and interstitial cystitis/painful bladder syndrome, as well as male and female sexual dysfunction. Understanding the true nature of the placebo-nocebo complex and the scope of its effect in functional urology could help urologists to maximize the positive effects of this phenomenon while minimizing its potentially negative effects.

Abstract
Biologics are indicated for the treatment of a wide range of conditions and have transformed care in several therapeutic areas; however, they are expensive for both health care systems and patients. The use of biosimilars, which are approved by the US Food and Drug Administration as being "highly similar" to the originator biologic, has the potential to change the health care landscape in the biologic space through considerable cost savings for both payors and patients. With the introduction of biosimilars, organizations are increasingly evaluating how to switch patients from originator biologics to biosimilars. While published studies have evaluated the outcomes of patients switched from originator biologics to biosimilars, there are few publications describing the process health care systems have used to adopt and switch patients to biosimilars. Since 2016, Kaiser Permanente Colorado (KPCO) has undertaken several biosimilar switches starting with the first biosimilar introduced to the market, filgrastim, and has been able to successfully switch 91.8% of patients receiving infliximab, 99.8% receiving rituximab, and 100% receiving filgrastim, trastuzumab, and bevacizumab originator biologics to their respective biosimilars. In an effort to support other health care systems and provide a framework for implementing biosimilar switches, the purpose of this paper is to describe the biosimilar switch model and share learnings from the KPCO experience.

Understanding genetic risk factors for common side effects of antidepressant medications. COMMUNICATIONS MEDICINE 2021; 1:45. [PMID: 35602235 PMCID: PMC9053224 DOI: 10.1038/s43856-021-00046-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Accepted: 10/21/2021] [Indexed: 01/03/2023] Open
Abstract
Background Major depression is one of the most disabling health conditions internationally. In recent years, new generation antidepressant medicines have become very widely prescribed. While these medicines are efficacious, side effects are common and frequently result in discontinuation of treatment. Compared with specific pharmacological properties of the different medications, the relevance of individual vulnerability is understudied. Methods We used data from the Australian Genetics of Depression Study to gain insights into the aetiology and genetic risk factors to antidepressant side effects. To this end, we employed structural equation modelling, polygenic risk scoring and regressions. Results Here we show that participants reporting a specific side effect for one antidepressant are more likely to report the same side effect for other antidepressants, suggesting the presence of shared individual or pharmacological factors. Polygenic risk scores (PRS) for depression associated with side effects that overlapped with depressive symptoms, including suicidality and anxiety. Body Mass Index PRS are strongly associated with weight gain from all medications. PRS for headaches are associated with headaches from sertraline. Insomnia PRS show some evidence of predicting insomnia from amitriptyline and escitalopram. Conclusions Our results suggest a set of common factors underlying the risk for antidepressant side effects. These factors seem to be partly explained by genetic liability related to depression severity and the nature of the side effect. Future studies on the genetic aetiology of side effects will enable insights into their underlying mechanisms and the possibility of risk stratification and prophylaxis strategies. Antidepressants are commonly prescribed medications, but adverse side effects are cause for treatment discontinuation. We analysed data from a large group of adults who have taken antidepressants to understand why some people experience specific side effects. Our results suggest that a person’s genetic characteristics play a role. For example, participants genetically predisposed to a higher body mass index were more likely to report weight gain from antidepressants. These results open up the possibility of predicting adverse side effects as we increase our knowledge on the genetics of related complex traits. Future studies can focus on performing large-scale genetic studies of antidepressant side effects to gain further insights into the mechanisms underlying antidepressant side effects and to identify genetic markers of side effects that could be used in the clinic. Campos et al. study the genetic aetiology of antidepressant side effects. Using data from the Australian Genetics of Depression study, the authors show that polygenic risk scores for traits such as BMI, insomnia and headaches have a shared genetic basis with side effects to commonly used antidepressant drugs.

Abstract
Objectives To evaluate an intervention to reduce the nocebo effect (NE) when switching from the originator infliximab (OI) to the infliximab biosimilar SB2 in chronic inflammatory rheumatic disease (CIRD). Methods An intervention was built with healthcare professionals (HPs) and a patient representative, based on a systematic review of interventions reducing the NE in musculoskeletal diseases and semi-directed questioning of five patients. Our strategy consisted of training HPs, switch information given by the nurses, a consistent vocabulary. All CIRD patients switched from OI to SB2 were included for the intervention. The primary outcome was the SB2 retention rate (RR) at 34 weeks. Secondary outcomes were the SB2 RR at 12 months, discontinuation rates due to a possible NE and comparison with a historical cohort of CIRD patients receiving the OI and 6 published European cohorts. Results 45 patients were included from March 2018 (rheumatoid arthritis, n=17, spondylarthritis, n=28). After 34 weeks, the SB2 RR was 91.2%, similar to the historical cohort RR (p=0.41) but higher than the 3 European cohort RRs (p<0.05). At 12 months, the SB2 RR was 84.5% vs 88.4% for the historical cohort (p=0.52). SB2 discontinuation due to a possible NE was 6.6% after 12 months. Conclusions A tailored communication with a prominent role of nurses reduced the NE in non-medical switches from the OI to SB2 as compared to published results. The RR was similar to the historical cohort RR. The methodology used to construct this intervention may help improve the outcomes of switches with upcoming biosimilars.

Abstract
Generic medicines have been available to consumers for ∼40 years, with varying degrees of uptake in different countries. Despite offering equivalent therapeutic qualities, generic medicines still struggle to be accepted by consumers. This study examines the role of a consumer's affective state and framing effects on the purchase of a branded versus a generic pharmaceutical product. These issues are examined in an experiment, with independent manipulations of consumer anxiety levels and the framing of generic alternatives by the pharmacist. The sample comprised 426 men and women within Australia who completed an online survey with a scenario of purchasing a pharmaceutical after visiting a General Practitioner. Results indicate that those consumers experiencing higher levels of anxiety and where the doctor prescribed the branded medicine are more likely to choose branded medicines over cheaper, generic alternatives. The effect of framing the generic alternative as either 'generic' or 'cheaper' was not significant.

Abstract
Introduction
Multiple expert panels at Kaiser Permanente approved infliximab-dyyb (Inflectra®), a biosimilar to the reference product infliximab (Remicade®), to be the preferred infliximab agent for therapeutic substitution from infliximab for adult patients with dermatologic, rheumatologic, and/or gastroenterologic diagnoses. The objective of this study was to assess the safety and effectiveness of infliximab-dyyb for Kaiser Permanente Northern California patients with psoriatic and rheumatoid arthritis who switched from infliximab to infliximab-dyyb.
Methods
This was an observational, data-only, non-inferiority study assessing adult patients with a rheumatologic condition of psoriatic arthritis (PsA) or rheumatoid arthritis (RA) who were switched from infliximab to infliximab-dyyb or used infliximab continuously in the Northern California region of Kaiser Permanente from May 2017 through May 2018. Both groups were followed for 12 months. The primary effectiveness outcome was disease worsening requiring acute care defined as emergency room visit or hospitalization related to the rheumatologic condition or orthopedic surgery intervention. Non-inferiority was set at an upper limit of 4%.
Results
A total of 70 individuals were identified as continuing infliximab and 727 individuals were switched to infliximab-dyyb. There were 2 patients (2.9%) in the infliximab group and 22 patients (3.0%) in the infliximab-dyyb group who experienced disease worsening requiring acute care (P = 0.03 for non-inferiority).
Conclusion
There was no increased risk of disease worsening requiring acute care in patients with RA or PsA who switched from infliximab to infliximab-dyyb when compared to patients who remained on infliximab in this population.

Abstract
In the USA, an interchangeability designation provides biosimilar sponsors with a pathway for achieving what is standard for small-molecule generics: pharmacy-level auto-substitution for an innovator. No other major health authority links interchangeability to automatic substitution, as all require the involvement of the prescriber or patient in a medication change. This editorial considers the clinical impact and practicality of auto-substitution. First, interchangeability is linked to non-medical switching (NMS), the practice of switching treatment in patients with stable disease for non-clinical reasons. NMS may generate negative sentiment in those unwilling or reluctant to switch, which can adversely impact treatment outcomes (i.e., nocebo effect). Indeed, in real-world studies of tumor necrosis factor inhibitors, discontinuation rates have been shown to be higher in patients switched to biosimilars for non-medical reasons than in historical cohorts maintained on innovators. Second, interchangeability may impede pharmacovigilance and traceability, as not all jurisdictions require innovators and biosimilars to have distinct biologic names. Third, an interchangeability designation from the US Food and Drug Administration only permits a biosimilar to be automatically substituted for its innovator, not other biosimilars (if available). Pharmacist education would be needed to avoid off-label, automatic substitution among biosimilars of a single innovator. Last, once granted, an interchangeability designation exists in perpetuity under current US federal law. However, the supply chains of innovators and biosimilars are maintained independently, with no requirement for reconfirmation of biosimilarity or interchangeability. We feel that additional guidance is needed for the auto-substitution of biosimilars and innovators to become a reality.

Abstract
Introduction: Randomized clinical trials (RCTs) are useful to study the role of individual and contextual factors in which therapies vs placebos are administered and to provide an important perspective for understanding the phenomenon of nocebo-related risks.Areas covered: The results of nocebo effects in RCT placebo groups, measured in terms of adverse events (AEs) and dropouts, will be presented as an explicative framework for the COVID-19 pandemic. Currently, SARS-CoV-2 vaccines are the only RCTs routinely conducted during the pandemic. Information about efficacy and safety of different vaccines represents a fertile ground for nocebo phenomena. Individual and contextual factors will be emphasized in order to understand the presence of a refusal of immunization associated with a specific vaccine considered less effective and safe. Critical aspects and some guidelines will be presented in order to counteract the nocebo effects and to improve adherence to drug treatments and the vaccination campaign.Expert opinion: The nocebo effect could explain the presence of strong resistance in European countries to immunization with a vaccine perceived as less effective, compared to others. Increased awareness of the nocebo effect would be relevant as it could lead to a greater participation in the vaccination campaign and in protecting individuals against SARS-CoV-2 infection.

Abstract
BACKGROUND Antidepressant efficacy is influenced by patient expectations and, in randomized controlled trials (RCTs), the probability of receiving a placebo. It is unclear whether tolerability demonstrates a similar pattern. This study aimed to determine whether study design influences adverse event (AE) rates in antidepressant trials for subjects receiving active treatment or placebo. METHODS RCTs comparing one antidepressant to another antidepressant, placebo, or both in major depressive disorder (MDD) (1996-2018) were retrieved from Medline and PsycINFO. Clinicaltrials.gov was searched for unpublished trials. Of 1,997 studies screened, 77 trials were included. Studies were classified as drug-drug, drug-drug-placebo, or drug-placebo based on design and overall number of subjects experiencing any AE was recorded. Subgroup meta-analysis of proportions and meta-regression techniques were used to compare AE rates across study designs in patients receiving active antidepressant treatment and placebo. RESULTS Among the actively treated, AE rates were lower in drug-drug trials (58.5%) compared to drug-drug-placebo (75.7%) and drug-placebo (76.4%) (the model reported coefficients for percent differences between AE rates of different study designs were B=17.0, p<0.001 and B=17.8, p<0.001, respectively). AE rates in patients receiving placebo were not different between study designs. LIMITATIONS The present study is limited by the diverse range of study populations, variability in reporting of AEs, and specific antidepressants employed in the included trials. CONCLUSIONS The inclusion of a placebo arm in the study design was unexpectedly associated with higher rates of AEs among patients receiving active medication in antidepressant trials. This observation has important implications for interpretation of trial tolerability findings.

Abstract
BACKGROUND Biologics have revolutionized the treatment of inflammatory bowel disease (IBD). However, these drugs had a significant influence on treatment-related costs, which resulted in the development of biosimilars. OBJECTIVE This systematic review and meta-analysis aimed to evaluate the drug discontinuation rate in the IBD population who switched from originator to biosimilars in real-world switching studies and address potential nocebo effects as reasons for drug discontinuation. METHODS Medline (via PubMed), EMBASE, Cochrane Library, and abstract databases of selected congresses were screened for reports of monoclonal antibody (mAb) switching with a minimum post-switch follow-up of >6 months or three infusions. All available information on discontinuation rates was assessed. RESULTS A total of 30 observational studies were included, involving 3,594 patients with IBD. Twenty-six studies reported a switch from infliximab to CT-P13, two studies involved a switch to SB2, and switching information was not available in two studies. The discontinuation rates were 8%, 14%, and 21% at 6, 12, and 24 months, respectively. The main reasons for drug discontinuation and their respective risks were: disease worsening (2%), remission (4%), loss of adherence (4%), adverse events (5%), and loss of response (7%). The quality of the evidence ranged from low to very low depending on the outcome analyzed. Subjective symptoms leading to drug discontinuation were infrequently reported, and the nocebo effect was clearly assessed in just one of the included papers. CONCLUSION Discontinuation rates following a switch to a biosimilar in patients with IBD increase over time. However, it was not possible to confirm the nocebo effect as a reason for discontinuation. Therefore, long-term studies evaluating the use of biosimilars to monitor adverse events and potential nocebo effects in post-marketing surveillance are still needed.

Abstract
BACKGROUND The exact monitoring of the therapeutic-range international normalized ratio (INR) after left ventricular assist device (LVAD) implantation is an important aim to reduce the risk of thrombosis or bleeding complications. Service providers offer a telemedical anticoagulation service (CS). METHODS We compared LVAD patients using the CS (n = 15) to those who received regular medical care (RMC; n = 15) to investigate if telemedicine supervision increased the INR-specific time in the therapeutic range (TTR) during anticoagulation. All patients received self-management training for phenprocoumon medication according to their INR value. INR values were documented for 12 months. A survey (scale: 1 = not satisfied and 10 = very satisfied) was used to determine patient's satisfaction and psychological well-being. RESULTS A total of 1,798 INR measurements were analyzed. The TTRRosendaal was higher in patients undergoing RMC (78.1 ± 14.3%) compared with that in patients using the CS (58.3 ± 28.0%, p = 0.03). The patient's satisfaction with the coagulation setting at the beginning of the study (RMC: 6.7 ± 3.1, CS: 7.2 ± 3.0, p = 0.74) and psychological wellbeing (RMC: 6.5 ± 1.9, CS: 6.5 ± 2.7, p = 0.97) were comparable between both groups. CONCLUSION We found that INR self-management is superior regarding the efficiency of post-LVAD anticoagulation therapy when compared with telemedical (CS)-based INR management in a small study cohort. Intensive training by experienced staff was able to replace CS.

The Unintended Consequences of Adverse Event Information on Medicines' Risks and Label Content. Pharmaceut Med 2020; 34:369-380.

Abstract
Patients and prescribers need to be aware of adverse drug events to minimize the risk of their occurrence and the severity with which they appear. However, numerous studies show that being informed about adverse events can increase the possibility of suffering from them. Patients tend to overestimate the likelihood of experiencing the adverse events included in the label, and this can contribute to worsening the negative expectations which are at the root of the nocebo effect. In fact, patients can become anxious after reading the undesirable effects section of the leaflet and, in addition to suffering from the nocebo effect, might not take a drug they could benefit from due to the fear of experiencing adverse events. In addition, patients' attention can focus towards non-specific symptoms of daily living that can be misattributed to the drug and included in the labelling. This article proposes a number of suggestions to reduce the abovementioned unintended effects associated with labelling, namely, an increased focus on the excess risk of experiencing adverse events rather than crude incidence, using attribute framing to help patients to better understand the risk of experiencing adverse events, dividing the undesirable effect section of the leaflet into subsections according to the level of evidence supporting causal relationships and, finally, restricting the addition of non-specific adverse events that are also symptoms of daily living to only those where there is enough evidence to show they have been caused by the drug. More studies on how to minimize the nocebo effect induced by adverse event information should be performed, and these should be done in collaboration with health authorities, to reach a shared consensus on how to better present adverse event information in the label.

Abstract
Background Idiopathic head tremor syndrome is a paroxysmal movement disorder of unknown etiology. Spontaneous remission may occur, but owners may request treatment in severely affected dogs with continued episodes. Controlled studies of the disease are not available. Hypothesis/Objectives A drug with gamma amino butyric acid‐ergic and anxiolytic effects will decrease head tremor episodes. Animals Twenty‐four dogs with severe nonremitting head tremor and presumptive clinical diagnosis of idiopathic head tremor syndrome. Methods Prospective, blinded, placebo‐controlled clinical trial to compare imepitoin with placebo in dogs with frequent episodes of idiopathic head tremor. Evaluation of efficacy used the quotient T2/T1 that represented prolongation of the head tremor‐free period compared to a 3‐month baseline. A dog was considered a responder if tremors subsided or if the head tremor‐free period was 3× longer than the longest period during baseline (T2/T1 ≥ 3). Sample size calculations considered a large effect of imepitoin on T2/T1 (Cohen's d = 0.8). Results There were no responders in the placebo group (0/12). In the imepitoin group, the responder rate was 17% (2/12; P = .18) with T2/T1 3.8 and 4.0. Mean T2/T1 was 1.0 ± 1.4 in the imepitoin and 0.4 ± 0.4 in the placebo group (P = .37). Conclusion and Clinical Importance Imepitoin did not result in a significant overall benefit. Future studies should focus on treatment of subgroups with a common pathophysiology and similar comorbidities.

Breast Cancer Chemoprevention: Use and Views of Australian Women and Their Clinicians. Cancer Prev Res (Phila) 2020; 14:131-144. [PMID: 33115784 DOI: 10.1158/1940-6207.capr-20-0369] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 08/27/2020] [Accepted: 10/15/2020] [Indexed: 11/16/2022]
Abstract
Guidelines endorse the use of chemoprevention for breast cancer risk reduction. This study examined the barriers and facilitators to chemoprevention use for Australian women at increased risk of breast cancer, and their clinicians. Surveys, based on the Theoretical Domains Framework, were mailed to 1,113 women at ≥16% lifetime risk of breast cancer who were enrolled in the Kathleen Cuningham Foundation Consortium for Research into Familial Breast Cancer cohort study (kConFab), and their 524 treating clinicians. Seven hundred twenty-five women (65%) and 221 (42%) clinicians responded. Only 10 (1.4%) kConFab women had ever taken chemoprevention. Three hundred seventy-eight (52%) kConFab women, two (3%) breast surgeons, and 51 (35%) family physicians were not aware of chemoprevention. For women, the strongest barriers to chemoprevention were side effects (31%) and inadequate information (23%), which operate in the Theoretical Domains Framework domains of "beliefs about consequences" and "knowledge," respectively. Strongest facilitators related to tamoxifen's long-term efficacy (35%, "knowledge," "beliefs about consequences," and "goals" domains), staying healthy for family (13%, "social role" and "goals" domains), and abnormal breast biopsy (13%, "environmental context" domain). The strongest barrier for family physicians was insufficient knowledge (45%, "knowledge" domain) and for breast surgeons was medication side effects (40%, "beliefs about consequences" domain). The strongest facilitators for both clinician groups related to clear guidelines, strong family history, and better tools to select patients ("environmental context and resources" domain). Clinician knowledge and resources, and beliefs about the side-effect consequences of chemoprevention, are key domains that could be targeted to potentially enhance uptake. PREVENTION RELEVANCE: Despite its efficacy in reducing breast cancer incidence, chemoprevention is underutilised. This survey study of Australian women and their clinicians used behavioural change theory to identify modifiable barriers to chemoprevention uptake, and to suggest interventions such as policy change, educational resources and public campaigns, that may increase awareness and use.See related Spotlight by Vogel, p. 1.

Abstract
Background Thorough information of the patient is an integral part of the process of shared decision making. We aimed to investigate if detailed information about medication may induce nocebo (or placebo) effects. Methods We conducted a randomized, single-blind, pilot-study including n = 51 psychiatric in-patients aged between 18 and 80 years with a depressive disorder and accompanying sleeping disorders. In the intervention group we provided thorough information about adverse effects, while the control group received only a simple consent procedure. In both groups, patients received an open-label placebo pill instead of their sleeping medication. Results No statistically significant differences between the intervention group and the control group were found regarding the main outcome parameter (a visual analogue scale indicating impairment by the new pill). Conclusion In this study, we were not able detect an effect of informed consent vs. simple consent on the emergence of placebo or nocebo effects. This finding is contrary to most assumptions and publications about this topic. Trial registration Trial registration number: DRKS00017653, registered August 30th 2018. Retrosprectively registered.
