Project description:BackgroundThere is very limited evidence examining serious systemic adverse events (SSAEs) and post-injection endophthalmitis of intravitreal bevacizumab (IVB) and intravitreal ranibizumab (IVR) treatments in Thailand and low- and middle-income countries. Moreover, findings from the existing trials might have limited generalizability to certain populations and rare SSAEs.ObjectivesThis prospective observational study aimed to assess and compare the safety profiles of IVB and IVR in patients with retinal diseases in Thailand.MethodsBetween 2013 and 2015, 6354 patients eligible for IVB or IVR were recruited from eight hospitals. Main outcomes measures were prevalence and risk of SSAEs, mortality, and endophthalmitis during the 6-month follow-up period.ResultsIn the IVB and IVR groups, 94 and 6% of patients participated, respectively. The rates of outcomes in the IVB group were slightly greater than in the IVR group. All-cause mortality rates in the IVB and IVR groups were 1.10 and 0.53%, respectively. Prevalence rates of endophthalmitis and non-fatal strokes in the IVB group were 0.04% of 16,421 injections and 0.27% of 5975 patients, respectively, whereas none of these events were identified in the IVR group. There were no differences between the two groups in the risks of mortality, arteriothrombotic events (ATE), and non-fatal heart failure (HF). Adjustment for potential confounding factors and selection bias using multivariable models for time-to-event outcomes and propensity scores did not alter the results.ConclusionsThe rates of SAEs in both groups were low. The IVB and IVR treatments were not associated with significant risks of mortality, ATE, and non-fatal HF.Trial registrationThai Clinical Trial Registry identifier TCTR20141002001.

Project description:IntroductionTo assess the safety profile of the intravitreal ranibizumab biosimilar molecule, Razumab® (Intas Pharmaceuticals, Ahmedabad, India) in chorioretinal disorders under real-world conditions.MethodsThis was a multicenter, retrospective chart review which included patients from 15 centers receiving intravitreal Razumab (IVRz) injections from 2016 to 2020. Patient demographics, ocular examination data, and detailed safety information regarding serious adverse events (SAE) or serious adverse drug reactions (sADR), and non-serious AEs (nsAE) or non-serious ADRs (nsADR) occurring within 1 month of IVRz injections were compiled.ResultsA total of 6404 eyes of 6404 patients received 9406 IVRz injections [mean (± SD) = 1.49 (± 0.63)] during 4.25 years. Adverse events were reported after 1978 injections (21.03%): 64.16% nsAE, 32.96% nsADR, 2.37% sADR, and 0.51% SAE. The most frequent adverse events were subconjunctival hemorrhage (8.2% of total injections), transient blurring of vision (6.5% of total injections), and mild ocular pain (5.27% of total injections). Serious ocular (31 cases with retinal pigment epithelial tears [0.33%], two cases of non-infectious vitritis [0.02%], and one case of endophthalmitis [0.01%]) and systemic (seven patients with non-fatal myocardial infarction [0.12%] and six patients with non-fatal cerebrovascular accident [0.09%]) adverse events were infrequent.ConclusionThe study reports the largest pooled safety data on IVRz use in a real-world scenario. The results did not raise any new ocular or systemic safety concerns for the biosimilar agent, with the incidence and spectrum of adverse reactions similar to those reported with other anti-vascular endothelial growth factor (anti-VEGF) drugs. The real-world evidence suggests that IVRz is a safe anti-VEGF agent in the management of chorioretinal disorders.

Project description:Secukinumab is an anti-IL-17 monoclonal antibody approved for treating psoriasis and various arthritides. A comprehensive evaluation of its safety, especially in a real-world setting, is necessary. This study aimed to describe the adverse events (AE) associated with secukinumab use using the United States Food and Drug Administration Adverse Event Reporting System (FAERS) database. FAERS data files containing AE reports from 2015 to 2021 were downloaded for data mining. Primary or secondary suspect medications indicated for psoriasis were identified and analyzed. Medical dictionary for regulatory activities (MedDRA version 24.1) was used to analyze the AE terms. To detect potential safety signals of AE from secukinumab use, disproportionality analysis was used. A total of 365,590 adverse event reports were identified; of these, 44,761 reports involved the use of secukinumab. Safety signals were identified for ocular infections and gastrointestinal adverse events at the standardised MedDRA query level. Safety signals for oral candidiasis, oral herpes, conjunctivitis, eye infections, and ulcerative colitis were identified at the preferred term level. The findings of our study are consistent with those of earlier studies, such as the increased risk of infections and inflammatory bowel disease. However, our study also identified additional safety signals that need to be further evaluated.

Project description:To evaluate the effect of intravitreal (IVT) bevacizumab in neovascular age-related macular degeneration (AMD) on global choroidal hemodynamics, as measured by ocular pulse amplitude (OPA).This was a two-center prospective study (Sheba Medical Center, Israel, and University Hospitals Leuven, Belgium). AMD patients who required IVT bevacizumab (1.25 mg/0.05 mL; first or repeated) were examined three times: at days 0 (prior to injection), 7 (±3), and 28 (±7) postinjection. At each visit, OPAs of both eyes were measured using the Pascal dynamic contour tonometer (DCT). A paired t-test between preoperative and postoperative OPA was conducted. Pearson correlation was used to evaluate the influence of various measured parameters on DCT-OPA.A total of 38 neovascular AMD patients were recruited, and 30 patients were included in the final analysis (18 females and 12 males; age 78.8 ± 5.82 years [mean ± standard deviation]). A good correlation was found throughout the study between the DCT-intraocular pressure (IOP) and Goldmann IOP and between DCT-IOP and DCT-OPA. No change in OPA of bevacizumab-treated eyes was found between the visits (2.24 ± 0.73, 2.2 ± 0.86, and 2.23 ± 0.73 mm Hg at visits 1, 2, and 3, respectively; paired t-test: P = 0.77 between visits 1 and 2, P = 0.98 between visits 1 and 3). No correlations were found between DCT-OPA and age, heart rate, systemic blood pressure, axial length, keratometry readings, and central corneal thickness.OPA, an indirect measure of global choroidal hemodynamics, remains unchanged following IVT off-label bevacizumab. This finding adds to the growing evidence regarding the safety profile of bevacizumab in AMD treatment.

Project description:IntroductionThe diagnosis and management of atopic dermatitis (AD) is extensively addressed in detailed clinical guidelines. However, the high heterogeneity regarding presentation and progression and the increasingly broad therapeutic landscape suggest a complex real-world scenario, leading to multiple trajectories of AD patients.MethodsUsing a Delphi methodology for assessing the degree of consensus, we explored the views of a panel of dermatologists regarding the patients' trajectory through the diagnosis (block 1), treatment (block 2), and long-term management (block 3) of AD. Based on a systematic search of the literature, a scientific committee prepared a questionnaire of relevant items that were rated on a 10-point scale (from "totally agree" to "totally disagree") by a panel of dermatologists attending patients with AD in the hospital setting. Consensus was established based on predefined rules.ResultsThe final questionnaire included 58 items and was answered by 17 dermatologists. Overall, consensus was reached on 22 items (37.9%), each of which was a consensus for agreement. The consensus rates in blocks 1, 2, and 3 were 22.7%, 19.0%, and 86%, respectively.ConclusionsOur analysis revealed a remarkable lack of consensus on various aspects of the routine diagnosis and treatment of AD. These findings suggest the presence of unmet needs or limited implementation of guidelines for the management of AD and encourage further research to explore the causes of this low consensus on the management of AD in the real-world setting.

Project description:Evidence to support clinical decision making must be based on safety data that have been captured, analysed and interpreted in a robust and reliable way. Randomised real-world evidence (RRWE) studies provide the opportunity to evaluate the use of medicines in patients and settings representative of routine clinical practice. However, elements that underpin the design of RRWE studies can have a significant impact upon the analysis, interpretation and implications of safety data. In this narrative review, we use data from the Salford Lung Study; two prospective, 12-month, open-label, parallel-group, phase III randomised controlled trials conducted in primary care in the UK; to highlight the importance of capturing treatment modifications when attempting to evaluate safety events according to actual treatment exposure. We demonstrate that analysing safety data by actual treatment received (i.e. accounting for the treatment modifications that occur routinely in the primary care setting) provides additional insight beyond analysing according to randomised treatment strategy only. It is therefore proposed that understanding of safety data from RRWE trials can be optimised by analysing both by randomised group and by actual treatment received.

Project description:ObjectivesTo assess the safety of intravitreal bevacizumab (IVB) as a monotherapy and to evaluate the relationship between quality of treatment and adverse events.Data sourcesCochrane Library, Ovid MEDLINE, MEDLINE in-process, Ovid EMBASE and Toxicology Literature Online (TOXLINE) from January 2009 to May 2012. Studies included in an earlier systematic review were also assessed for inclusion.Study eligibility criteria, participants and interventionsRandomised controlled trials (RCTs), controlled trials or observational studies including ?10 participants reporting adverse events data following IVB monotherapy as a primary treatment in patients (aged 18?years or more) with any eye condition were included.Study appraisal and synthesis methodsStudy selection was undertaken independently by a minimum of two reviewers using pre-defined criteria. Data abstraction and quality assessment were performed by one reviewer, and then checked by a second reviewer. Study quality was assessed for only RCTs in accordance to the Cochrane Risk of Bias Tool. Additional items relating to safety data were also assessed. Results were tabulated or meta-analysed as appropriate.Results22 RCTs and 67 observational studies were included. Only two RCTs reported valid safety data. Rates of serious adverse events following treatment were low. There was insufficient data to explore the relationship between the incidence of adverse events and quality of IVB injection.LimitationsA majority of relevant existing studies were characterised by small sample sizes, unclear diagnostic criteria and reporting of safety outcomes.Conclusions and implications of key findingsAvailable evidence demonstrates low rates of serious local and systemic adverse events following treatment. However, the role of IVB quality in the incidence of adverse events remains unclear. Robust evidence is needed to examine the relationship between the incidence of adverse events and variables such as injection techniques, pre-existing risk factors (eg, immunosuppression, cross-contamination) and quality of IVB treatment.

Project description:BackgroundThere are 3 main epileptic conditions in hospital settings that may require intravenous antiepileptic treatment: status epilepticus, acute repetitive convulsive seizures, and postoperative seizures. Generic intravenous levetiracetam (IV LEV) (Focale; Great Eastern Drug Co, Bangkok, Thailand), has been reported to have comparable efficacy to original IV LEV for treating status epilepticus and acute repetitive convulsive seizures in a randomized controlled trial. At present, there are limited data on the efficacy and tolerability of generic intravenous LEV in real-world situations.ObjectiveThis study aimed to evaluate the clinical outcomes of generic IV LEV in a real-world setting.MethodsA retrospective study and analyses were conducted. All adult patients who used IV LEV at University Hospital, Khon Kaen University, Thailand from June 1, 2019, until February 15, 2020, were included. Data were analyzed and reported in terms of the efficacy and tolerability of generic IV LEV.ResultsNinety-three patients received IV LEV by 3 indications: status epilepticus, acute repetitive convulsive seizures, and postoperative seizures. The proportions of these 3 indications were 41.94% (39 patients), 9.67% (9 patients), and 48.39% (45 patients), respectively. The average seizure control rate at 24 hours was 89.25%. The seizure control rate was significantly higher in the acute repetitive convulsive seizures and postoperative seizure groups than in the status epilepticus group when generic IV LEV was given as the first-line treatment (75.00%; 88.37% vs 50.00%; P 0.035). The average length of hospital stay was 18.24 (25.40) days. There was no significant discharge status among the 3 groups (P = 0.348). Moreover, the average mortality rate was 5.38%. Side effects were reported in 14 patients (15.05%). The 2 most common side effects were vomiting and bronchospasm (3 patients; 3.22%). There were 10 patients with uncontrolled seizures at 24 hours (10.75%). The only factor associated with uncontrolled seizures at 24 hours was a history of epilepsy. The uncontrolled seizure group had a higher proportion of epilepsy patients than the seizure-controlled group (70.00% vs 33.73%; P = 0.037). Poor discharge status (not improved/death) was 18.28% (17 patients). There was no significant factor between those with an improved or poor discharge status.ConclusionsGeneric IV LEV was effective and relatively well tolerated in the 3 clinical settings (ie, status epilepticus, acute repetitive convulsive seizures, and postoperative seizures). Further clinical data are still required to confirm the results of this study.(Curr Ther Res Clin Exp. 2022; 83:XXX-XXX).

Project description:BACKGROUND:The promise of real-world evidence (RWE) is especially relevant to pediatrics, where medicines prescribed for children are often used without evidence derived from randomized clinical trials. OBJECTIVES:The aim of this systematic review was to describe the state of RWE in pediatrics by identifying observational studies published during 2016 that used RWE to assess medication safety or effectiveness in children. METHODS:An electronic search of PubMed was combined with an extended search of references within systematic reviews and expert suggestions. Studies were included if they reported on an infant or child under 18 years with exposure to medications; assessed safety or effectiveness; specified a comparison or control group, and were published in English in 2016. Data extraction was conducted by one team member using a standardized form and reviewed by a second team member. Study quality was assessed using the GRACE checklist for rating the quality of observational studies. RESULTS:After removing duplicates, 915 citations were screened and 29 studies met the eligibility criteria. Most of the eligible studies relied on primary data collection or chart review at a single institution and did not use the growing number of administrative or electronic health record databases available. One-quarter of the studies did not use well-established statistical methods to control for confounders. No single disease group or medication predominated, and age groups ranged from infants to adolescents. CONCLUSIONS:A small body of observational studies published in 2016 were categorized by the study team as using real-world data to assess medication safety or effectiveness in children. Studies varied in age groups, diseases or conditions, and methods, and may not have fully met the FDA definition of RWE. Our review indicates that the use of RWE is not fully developed in pediatrics, and suggests an opportunity to further develop capabilities and more fully leverage administrative and electronic health record databases to study medication safety and effectiveness in children. Our systematic review appears generalizable to pediatrics broadly, and documents that the high level of activity in RWE in general has had less of an impact on pediatrics.

Project description:Microarrays were used to determine the efficacy of bevacizumab (a monoclonal antibody against the vascular endothelial growth factor and its receptors.) on endometrial cancer cells. Endometrial cancer is the most frequent gynecologic cancer in women. Long term outcomes for patients with advanced stage or recurrent disease are poor. Targeted molecular therapy against the vascular endothelial growth factor (VEGF) and its receptors constitute a new therapeutic option for these patients. The goal of our work was to assess the potential effectiveness of inhibition of VEGF/VEGFR signaling in a xenograft model of endometrial cancer using bevacizumab (Avastin, a humanized antibody against VEGFA). We also aimed to identify molecular markers of sensitivity or resistance to this agent. We show that bevacizumab retards tumor growth in athymic mice by inhibiting molecular components of signaling pathways that sustain cell survival and proliferation. We also demonstrate that resistance to bevacizumab may involve up-regulation of antiapoptotic genes and certain proto-oncogenes.
