Retrospective multicenter study of elderly patients with platinum-sensitive relapsed ovarian cancer treated with trabectedin and pegylated liposomal doxorubicin (pld) in a real-world setting: a geico study.

BACKGROUND: Trabectedin in combination with pegylated liposomal doxorubicin (PLD) is approved for the treatment of patients with platinum-sensitive relapsed ovarian cancer. Nevertheless, there is currently limited information regarding this treatment in elderly patients with ovarian cancer in a real-world setting. METHODS: This observational and multicentric study retrospectively evaluated trabectedin plus PLD in a real-world setting treatment of elderly patients diagnosed with platinum-sensitive relapsed ovarian cancer, treated according to the Summary of Product Characteristics (SmPC) from 15 GEICO-associated hospitals. Patients ≥ 70 years old at the time of treatment initiation and platinum-free intervals ≥ 6 months were considered eligible. RESULTS: Forty-three patients with a median age of 74.0 years were treated between January 1st, 2015, and December 31st, 2019 in 15 Spanish centers. Four patients achieved complete response (9.3%), 14 (32.6%) partial response, and 13 (30.2%) stable disease as the best radiological response. In the analysis of biological overall response according to CA125 serum levels (i.e., Rustin criteria), 14 responded to the treatment (32.6%), 11 responded and normalized (25.6%), three patients stabilized (7.0%) and three progressed (7.0%). Median progression-free survival (PFS) and overall survival (OS) in the study population were 7.7 and 19.5 months, respectively. The most common grade 3/4 adverse events were neutropenia (n = 8, 18.7%) and asthenia (n = 5, 11.6%). CONCLUSIONS: This analysis demonstrated that trabectedin combined with PLD is a feasible and effective treatment in elderly patients with platinum-sensitive relapsed ovarian cancer, showing an acceptable safety profile, which is crucial in the palliative treatment of these patients.

Establishment of RWS guidance reflecting contributions of China to regulatory science.

China's accession to the ICH has accelerated the advancement of its regulatory science. To foster innovation and improve the efficiency of pharmaceutical research and development, the China National Medical Products Administration (NMPA) encourages the use of real-world evidence (RWE) to support drug regulatory decision-making and has constructed a series of real-world study (RWS) related guidance, reflecting the contribution of the NMPA to the field of RWS in drug clinical development. Based on the four guidelines on RWE, real-world data (RWD), RWS design and protocol development, and communication with regulatory authorities, the guidance has been extended to more specific clinical applications, such as oncology, rare diseases, pediatric drugs, and traditional Chinese medicine. This paper reviews the core content and features of the series of RWS guidelines, presents their role in promoting drug development, and discusses challenges of using RWE in support of drug regulatory decision-making in China.

Impact of Human Papillomavirus Vaccine Against Anal Human Papillomavirus Infection, Anal Intraepithelial Neoplasia, and Recurrence of Anal Intraepithelial Neoplasia: A Systematic Review and Meta-analysis.

BACKGROUND: We sought to summarize human papillomavirus (HPV) vaccine efficacy/effectiveness (VE) against anal HPV infection and anal intraepithelial neoplasia (AIN). METHODS: We performed literature review and meta-analysis to estimate VE, stratified by age and analytic population (per-protocol efficacy [PPE] or intention-to-treat [ITT] population in clinical trials, or all participants in real-world studies). RESULTS: We identified 6 clinical trials and 8 real-world studies. In participants vaccinated at age ≤26 years (mainly human immunodeficiency virus [HIV]-negative individuals), significant VE against incident/prevalent anal HPV infection was reported in clinical trials, with a higher estimate in PPE (2 studies with 2390 participants; VE, 84% [95% confidence interval (CI), 77%-90%]; I2 = 0%) than ITT (2 studies with 4885 participants; 55%, 39%-67%; I2 = 46%) populations or in real-world studies (4 studies with 2375 participants; 77%, 40%-91%; I2 = 81%). HPV vaccination at age ≤26 years was associated with significant VE in preventing persistent anal HPV infection and AIN. No significant VE against anal HPV infection or AIN was found in persons vaccinated at age >26 years (mainly people living with HIV). CONCLUSIONS: There is strong evidence for high VE against anal HPV infection and AIN in HIV-negative individuals vaccinated at age ≤26 years. However, the lower impact in ITT than in PPE populations and the lack of significant effect in people living with HIV aged >26 years indicates that vaccines have the higher impact in populations with less sexual exposure to anal HPV.

The clinical impact of Lumacaftor-Ivacaftor on structural lung disease and lung function in children aged 6-11 with cystic fibrosis in a real-world setting.

BACKGROUND: Data from clinical trials of lumacaftor-ivacaftor (LUM-IVA) demonstrate improvements in lung clearance index (LCI) but not in FEV1 in children with Cystic Fibrosis (CF) aged 6-11 years and homozygous for the Phe508del mutation. It is not known whether LUM/IVA use in children can impact the progression of structural lung disease. We sought to determine the real-world impact of LUM/IVA on lung structure and function in children aged 6-11 years. METHODS: This real-world observational cohort study was conducted across four paediatric sites in Ireland over 24-months using spirometry-controlled CT scores and LCI as primary outcome measures. Children commencing LUM-/IVA as part of routine care were included. CT scans were manually scored with the PRAGMA CF scoring system and analysed using the automated bronchus-artery (BA) method. Secondary outcome measures included rate of change of ppFEV1, nutritional indices and exacerbations requiring hospitalisation. RESULTS: Seventy-one participants were recruited to the study, 31 of whom had spirometry-controlled CT performed at baseline, and after one year and two years of LUM/IVA treatment. At two years there was a reduction from baseline in trapped air scores (0.13 to 0.07, p = 0.016), but an increase from baseline in the % bronchiectasis score (0.84 to 1.23, p = 0.007). There was no change in overall % disease score (2.78 to 2.25, p = 0.138). Airway lumen to pulmonary artery ratios (AlumenA ratio) were abnormal at baseline and worsened over the course of the study. In 28 participants, the mean annual change from baseline LCI2.5 (-0.055 (-0.61 to 0.50), p = 0.85) measurements over two years were not significant. Improvements from baseline in weight (0.10 (0.06 to 0.15, p < 0.0001), height (0.05 (0.02 to 0.09), p = 0.002) and BMI (0.09 (0.03 to 0.15) p = 0.005) z-scores were seen with LUM/IVA treatment. The mean annual change from baseline ppFEV1 (-2.45 (-4.44 to 2.54), p = 0.66) measurements over two years were not significant. CONCLUSION: In a real-world setting, the use of LUM/IVA over two years in children with CF aged 6-11 resulted in improvements in air trapping on CT but worsening in bronchiectasis scores. Our results suggest that LUM/IVA use in this age group improves air trapping but does not prevent progression of bronchiectasis over two years of treatment.

Short- and Long-Term Survival of Metastatic Biliary Tract Cancer in the United States From 2000 to 2018.

INTRODUCTION: Information about survival outcomes in metastatic biliary tract cancer (BTC) is sparse, and the numbers often quoted are based on reports of clinical trials data that may not be representative of patients treated in the real world. Furthermore, the impact of more widespread adoption of a standardized combination chemotherapy regimen since 2010 on survival is unclear. METHODS: We performed an analysis of the Surveillance, Epidemiology, and End Results database to determine the real-world overall survival trends in a cohort of patients with metastatic BTC diagnosed between the years 2000 and 2017 with follow-up until 2018. We analyzed data for the entire cohort, evaluated short-term and long-term survival rates, and compared survival outcomes in the pre-2010 and post-2010 periods. Survival analysis was performed using the Kaplan-Meier method, and Cox proportional hazard models were used to evaluate factors associated with survival. RESULTS: Among 13, 287 patients, the median age was 68 years. There was a preponderance of female (57%) and white (77%) patients. Forty-one percent died within 3 months of diagnosis (short-term survivors) and 20% were long-term survivors (12 months or longer). The median overall survival (OS) for the entire cohort was 4.5 months. Median OS improved post-2010 (4.5 months) compared to pre-2010 (3.5 months) (P < .0001). On multivariate analysis, age <55 years, intrahepatic cholangiocarcinoma, surgical resection, and diagnosis post-2010 were associated with lower hazard of death. CONCLUSION: The real-world prognosis of metastatic BTC is remarkably poorer than described in clinical trials because a large proportion of patients survive less than three months. Over the last decade, the improvement in survival has been minimal.

Entecavir combined with interferon-α Is superior to entecavir monotherapy in reducing hepatic and extrahepatic cancer in patients with chronic hepatitis B.

BACKGROUND: The objective of this study was to assess whether entecavir (ETV) in combination with interferon-α (IFN-α) could reduce hepatocellular cancer (HCC) and extrahepatic cancers (EHCs) in patients with chronic hepatitis B (CHB). METHODS: The cohort consisted of 4194 patients with CHB treated with ETV combined with IFN-α or ETV monotherapy at a tertiary hospital in Beijing, China, from January 2009 to December 2017. The risks, hazard ratios (HRs), and 95% confidence intervals (CIs) of HCC and EHCs were compared in the 2 groups. RESULTS: In a multivariate Cox regression analysis, a significantly lower risk of HCC (HR, 0.6; 95% CI, 0.3-0.9; P = .0310) and a marginally significantly lower risk of EHCs (HR, 0.2; 95% CI, 0.02-1.3; P = .0854) were observed in the group receiving ETV combined with IFN-α in comparison with the ETV monotherapy group. The annual virological response rates were significantly higher in the combination therapy group versus the monotherapy group (33.8% vs 21.2%; P < .0001), but the hepatitis B surface antigen (HBsAg) seroclearance rates were not (1.2% vs 0.9%; P = .8537). The HRs were consistent with propensity score-based matching, inverse probability weighting adjustments, and adjustments for virological response and HBsAg seroclearance. CONCLUSIONS: ETV combined with IFN-α therapy is superior to ETV monotherapy in reducing the risk of HCC and EHCs for patients with CHB. People who can tolerate and benefit from IFN-α therapy could consider combination therapy.

Rationale, Strengths, and Limitations of Real-World Evidence in Oncology: A Canadian Review and Perspective.

Randomized controlled trials (RCTs) continue to be the basis for essential evidence regarding the efficacy of interventions such as cancer therapies. Limitations associated with RCT designs, including selective study populations, strict treatment regimens, and being time-limited, mean they do not provide complete information about an intervention's safety or the applicability of the trial's results to a wider range of patients seen in real-world clinical practice. For example, recent data from Alberta showed that almost 40% of patients in the province's cancer registry would be trial-ineligible per common exclusion criteria. Real-world evidence (RWE) offers an opportunity to complement the RCT evidence base with this kind of information about safety and about use in wider patient populations. It is also increasingly recognized for being able to provide information about an intervention's effectiveness and is considered by regulators as an important component of the evidence base in drug approvals. Here, we examine the limitations of RCTs in oncology research, review the different types of RWE available in this area, and discuss the strengths and limitations of RWE for complementing RCT oncology data.

Real-world efficacy of treatment with benralizumab, dupilumab, mepolizumab and reslizumab for severe asthma: A systematic review and meta-analysis.

BACKGROUND: Severe asthma is a major cause of morbidity. Some patients may benefit from biological therapies. Most evaluations of these treatments are derived from randomized controlled trials (RCTs), but few patients are eligible for these trials. Studies involving more diverse groups of participants exist, but there is a lack of precise pooled estimates. OBJECTIVE: This systematic review aims to evaluate the real-world efficacy of recently and nearly licensed biological therapies for severe asthma to assess the generalizability of the RCT data. METHODS: Clinical outcomes including exacerbation rate, oral corticosteroid usage, forced expiratory volume in 1 second (FEV1 ) and fractional exhaled nitric oxide (FeNO) were examined. Studies were assessed for risk of bias using the Critical Appraisal Skills Programme checklist tool. The certainty of evidence was assessed using Grading of Recommendations, Assessment, Development and Evaluations (GRADE). RESULTS: A total of 21 studies examining biologicals in real-world settings were identified; they mostly focused on benralizumab and mepolizumab. The introduction of biologicals reduced the annualzsed exacerbation rate significantly by -3.79 (95% confidence interval [CI] -4.53, -3.04), -3.17 (95% CI -3.74, -2.59) and -6.72 (95% CI -8.47, -4.97) with benralizumab, mepolizumab and reslizumab, respectively. Likewise, improvements were observed in FEV1 (0.17 L 95% CI 0.11, 0.24) and FeNO (-14.23 ppb 95% CI -19.71, -8.75) following the treatment with mepolizumab. After treatment with benralizumab, there was an increase in FEV1 (0.21 L 95% CI 0.08, 0.34). CONCLUSIONS: These data demonstrate that anti-IL5 biologicals may improve the clinical outcomes of patients with severe asthma in a clinic environment with similar effect sizes to RCTs. The data were mainly retrospective and unadjusted, so estimated effect sizes may not be reliable. More data are needed to acquire accurate effect estimates in different subpopulations of patients.

Ocrelizumab treatment in multiple sclerosis: A Danish population-based cohort study.

BACKGROUND AND PURPOSE: Real-world evidence regarding the effectiveness and safety of ocrelizumab for the treatment of multiple sclerosis (MS) is limited. The aim was to evaluate the effectiveness and safety of ocrelizumab treatment for MS in a real-world setting. METHODS: A nationwide population-based cohort study was conducted where clinical and magnetic resonance imaging data of MS patients enrolled prospectively in the Danish Multiple Sclerosis Registry who initiated ocrelizumab treatment between January 2018 and November 2020 were analyzed. RESULTS: A total of 1104 patients (85.7% relapsing-remitting MS [RRMS], 8.8% secondary progressive MS [SPMS], 5.5% primary progressive MS [PPMS]) were included, with a median follow-up period of 1.3 years. At baseline, the mean age was 41.4 years in the RRMS group, 44.5 years in the PPMS group and 50.3 years in the SPMS group. Median Expanded Disability Status Scale score was 2.5, 3.5 and 5.5, respectively. Most RRMS and SPMS patients had received previous disease-modifying therapies (87.5% and 91.8%, respectively), whereas PPMS patients were mostly treatment naïve (78.7%). After ocrelizumab initiation, 9.3% of the patients experienced a relapse and 8.7% a 24 weeks confirmed disability worsening. Conversely, 16.7% showed a 24 weeks confirmed disability improvement. After ~1 year of treatment, most patients (94.5%) were free of magnetic resonance imaging activity. Ocrelizumab was generally well tolerated, as side effects were only reported for 10% of patients, mostly consisting of infusion-related reactions and infections. CONCLUSIONS: It is shown that most MS patients treated with ocrelizumab are clinically stabilized and with an adverse event profile consistent with the experience from the pivotal clinical trials.

Real-World Patient Experience of CGRP-Targeting Therapy for Migraine: a Narrative Review.

PURPOSE OF REVIEW: To summarize available calcitonin gene-related peptide (CGRP)-targeting therapies for migraine and discuss their use in real-world populations. BACKGROUND: CGRP has long been a topic of interest in migraine pathophysiology, with new therapies targeting CGRP since 2018 for both the preventive and acute treatment of migraine. METHODS: We searched PubMed using keywords including "migraine," "CGRP," "real-world," "erenumab," "galcanezumab," "fremanezumab," "eptinezumab," "ubrogepant," "rimegepant," and "atogepant." We reviewed all pertinent studies and summarized main findings. We also compiled detailed patient characteristics (e.g., migraine diagnoses, medication overuse, prior treatment failures) and treatment outcome measures, such as 50% responder rates, reduction in migraine days, and adverse event rates in several tables. Overall, studies reporting real-world patient experiences of CGRP-targeting therapies suggested meaningful effectiveness for migraine treatment with response rates comparable to the numbers reported in clinical trials. Furthermore, studies suggested benefit in patients with multiple prior unsuccessful treatment trials, medication overuse, and complex medical comorbidities. In some studies, adverse event rates have been notably higher than reported in clinical trials. Additional long-term data is needed to further evaluate sustained efficacy, predictors of treatment response, and adverse events.

Analysing Subgroups and Treatment Discontinuation in a Finnish Cohort of Patients with Neovascular AMD.

PURPOSE: We aimed to study the regional detailed visual outcome and treatment discontinuation of neovascular age-related macular degeneration (nAMD). METHODS: Clinical records of 110 patients treated for nAMD at the sole referral centre in the Helsinki region were analysed retrospectively. The follow-up was up to the fourth year. RESULTS: The mean visual acuity (VA) at baseline was 56.3 (SD 16.2) letters. The mean last VA at the first year was 59.7 (20.2), and the corresponding values for the second, third, and fourth years were 60.8 (20.6), 60.0 (19.0), and 59.7 (19.3). The mean difference from baseline was +3.39 (SD 14.6), +3.59 (17.6), +0.08 (18.9), and +3.08 (14.3). The number of patients declined each year, with only 51% of the patients being in treatment until the fourth year. The patients with shorter duration of follow-up tended to have a lower baseline VA, lesser gains, and an earlier decline in VA. The VA levels at the last visit were poorer in the shorter follow group. The initial VA response predicted later VA, whereas VA at baseline, age, or sex had no effect. However, the effect vanished with a longer time in treatment. CONCLUSIONS: Long-term VA stabilization was obtained in a regional material. Patients with neovascular AMD consist of cohorts with varying visual outcome and treatment time. Many of the patients benefit from the treatment for some time, however. When comparing real-world results, the outcome of the different follow-up time cohorts should be considered. This calls for new methods for analysing real-world nAMD treatment results.

The effect of sodium-glucose transport protein 2 inhibitors on mortality and heart failure in randomized trials versus observational studies.

AIM: Randomized clinical trials (RCTs) allocating type 2 diabetes patients to treatment with sodium-glucose transport protein 2 (SGLT-2) inhibitors or placebo have found significant effects on the risk of heart failure and modest effects on mortality. In the wake of the first trials, a number of observational studies have been conducted, some of these reporting a mortality reduction of 50% compared to active comparators. In this review, we systematically assess and compare the results on all-cause mortality, cardiovascular mortality and heart failure hospitalization observed in RCTs with the results obtained in observational studies. METHOD: We performed a systematic bibliographical search including cardiovascular outcome trials and observational studies assessing the effect of SGLT-2 inhibitors on mortality and heart failure. RESULTS: Seven RCTs and 23 observational studies were included in the current review. The observed heterogeneity between study results for all-cause mortality (p-interaction < 0.001) and cardiovascular mortality (p-interaction < 0.001) was explained by study type, whereas this was not the case for heart failure (p-interaction = 0.18). CONCLUSION: Methodological considerations such as the omission of important confounders, immortal-time bias and residual confounding such as unmeasured social economic inequality may be the cause of the inflated results observed in observational studies and that calls for caution when observational studies are used to guide treatment of patients with type 2 diabetes.

Efficacy and tolerability of adjuvant perampanel: an Australian multicenter real-world observational study in refractory focal and generalized epilepsy syndromes.

PURPOSE: To explore the efficacy and tolerability of adjuvant perampanel (PER) and their associated risk factors in late add-on drug-resistant epilepsy. METHOD: Retrospective multicenter 'real-world' observational study. Consecutively identified patients commenced on PER, with mixed epilepsy syndromes, from nine Australian epilepsy centers. Primary efficacy endpoints were at least 50% reduction in seizure frequency (responders), seizure freedom, and retention at 6 and 12 months, following a 3-month titration period. Tolerability endpoints were cessation of PER for any reason, cessation of PER due to treatment-emergent adverse events (TEAE), or cessation due to inefficacy. Outcomes were assessed for a-priori risk factors associated with efficacy and tolerability. RESULTS: Three-hundred and eighty seven adults were identified and followed up for a median of 12.1 months (IQR 7.0-25.2). Focal epilepsy accounted for 79.6% (FE), idiopathic generalized epilepsy (IGE), 10.3% and developmental epileptic encephalopathy (DEE) 10.1%, of the cohort. All patients had drug-resistant epilepsy, 71.6% had never experienced six months of seizure freedom, and the mean number of antiepileptic medications (AEDs) prior to starting PER was six. At 12 months, with missing cases classified as treatment failure, retention was 40.0%, responder 21.7%, and seizure freedom 9.0%, whereas, using last outcome carried forward (LOCF), responder and seizure freedom rates were 41.3% and 14.7%, respectively. Older age of epilepsy onset was associated with a marginal increase in the likelihood of seizure freedom at 12-month maintenance (OR 1.04, 95% CI 1.02, 1.06). Male sex (adjusted OR [aOR] 2.06 95% CI 1.33, 3.19), lower number of prior AEDs (aOR 0.84, 95% CI 0.74, 0.96) and no previous seizure-free period of at least 6-month duration (aOR 2.04 95% CI 1.21, 3.47) were associated with retention. Perampanel combined with a GABA receptor AED was associated with a lower responder rate at 12 months but reduced cessation of PER. The most common TEAEs were neuropsychiatric (18.86%), followed by dizziness (13.70%), and sleepiness (5.68%). CONCLUSIONS: Adjuvant PER treatment, even in late-add on drug-resistant epilepsy is an effective and well-tolerated treatment for drug-resistant epilepsy.

Long-term outcomes of intravitreal therapy for symptomatic diabetic macular oedema in a real-world setting in Switzerland.

OBJECTIVE: To assess the long-term visual outcomes in eyes with symptomatic diabetic macular oedema (DME) under intravitreal treatment (IVT) in a clinical routine setting. METHODS: Patients with newly diagnosed DME were included in this retrospective study if they had received at least three IVTs and a follow-up period ≥ 2 years. Due to altered treatment patterns since the approval of ranibizumab for DME in 2012, patients were subdivided according to their first IVT before 2013 (group 1) or thereafter (group 2). The primary outcome measure was the evolution of best-corrected visual acuity (BCVA) over time. RESULTS: Of 217 eyes (191 patients) with DME, 151 eyes (117 patients) fulfilled the inclusion criteria (63 eyes in the first period, 88 in the second period). Mean follow-up time was 7.9 ± 3.1 (group 1) and 4.1 ± 1.4 years (group 2; p < 0.001). Visual gains were similar in the first year (group 1: + 5.3 ± 15.5, group 2: + 7.3 ± 12.2 Early Treatment Diabetic Retinopathy Study (ETDRS) letters; p = 0.44), but not thereafter (after 2 years in group 1: + 4.4 ± 15.0, group 2: + 8.3 ± 13.0 ETDRS letters; p = 0.038). During the first year, group 1 patients received less clinical examinations (group 1: 6.6 ± 3.3, group 2: 7.5 ± 2.1; p = 0.007) and less injections (group 1: 3.6 ± 2.7, group 2: 6.1 ± 2.7; p < 0.001). CONCLUSION: A greater visual gain, in response to more intensive treatment during the first year, was maintained for at least 5 years in group 2 subjects. Our data confirm that in a real-world setting, early intensive treatment results in satisfying long-term visual outcomes.

Cholesterol lowering therapies and achievement of targets for primary and secondary cardiovascular prevention in type 2 diabetes: unmet needs in a large population of outpatients at specialist clinics.

BACKGROUND: The well-established benefit of Low-Dense-Lipoprotein-cholesterol (LDL-c) lowering treatments (LLTs) has led clinical guidelines to lower the cardiovascular prevention targets. Despite this, there is a surprising scarcity of real-world studies (RWS) evaluating whether recommendations are applied in the routine clinical management of patients with type 2 diabetes (T2D). We therefore evaluated, in a large RWS, the pattern of LLTs use and the achievement of LDL-c targets in patients with T2D in Italian diabetes specialist clinics. METHODS: We collected data from 46 diabetes outpatient clinics (following 281,381 subjects), including 104,726 T2D patients, for whom use of LLTs between 2015 and 2016 was ascertained. We used the 2016 and 2019 European Atherosclerosis Society and European Society of Cardiology (EAS-ESC) guidelines to define cardiovascular risk categories, LDL-c targets, and the expected LDL-c reduction and cardiovascular benefit achievable with LLT intensification. RESULTS: 63,861 patients (61.0%) were on statin therapy, 9.2% of whom were also on ezetimibe. Almost all subjects were at high (29.3%) or very high (70.4%) cardiovascular risk, including 17% being in secondary prevention. Among very high-risk patients, 35% were not on statin despite half of them had LDL-c > 2.6 mmol/l, and only 15% of those on statins had LDL-c < 1.4 mmol/l. 83% of subjects in secondary prevention were on a statin, but half of them had LDL-c > 1.8 mmol/l. Overall, 35% and 14% of subjects achieved the LDL-c targets as suggested by 2016 and 2019 EAS-ESC Guidelines, respectively. Based on anticipated response to treatment, we estimated that 38% of the entire population would require high-intensity-statin (HI-statin), 27% a combination of HI-statin plus ezetimibe, and 27% the addition of proprotein-convertase-subtilisin/kexin-9 (PCSK9) inhibitors. These LLT intensifications would reduce the incidence of cardiovascular events by 32%, from 23.511 to 16.022 events per 100.000 patients/10-years (incidence-rate-ratio 0.68; 95% C.I 0.67-0.70, p < 0.001). CONCLUSIONS: Despite the increase in use of LLT in T2D over the last decades, a large proportion of subjects with T2D did not achieve their LDL-c targets. Given the very high cardiovascular risk of these patients, improving LLT is expected to have a dramatic impact on cardiovascular event prevention.

What Is Real-World Data? A Review of Definitions Based on Literature and Stakeholder Interviews.

BACKGROUND: Despite increasing recognition of the value of real-world data (RWD), consensus on the definition of RWD is lacking. OBJECTIVES: To review definitions publicly available for RWD to shed light on similarities and differences between them. METHODS: A literature review and stakeholder interviews were used to compile data from eight groups of stakeholders. Data from documents and interviews were subjected to coding analysis. Definitions identified were classified into four categories: 1) data collected in a non-randomized controlled trial setting, 2) data collected in a non-interventional/non-controlled setting, 3) data collected in a non-experimental setting, and 4) others (i.e., data that do not fit into the other three categories). The frequency of definitions identified per category was recorded. RESULTS: Fifty-three documents and 20 interviews were assessed. Thirty-eight definitions were identified: 20 out of 38 definitions (53%) were category 1 definitions, 9 (24%) were category 2 definitions, 5 (13%) were category 3 definitions, and 4 (11%) were category 4 definitions. Differences were identified between, and within, definition categories. For example, opinions differed on the aspects of intervention with which non-interventional/non-controlled settings should abide. No definitions were provided in two interviews or identified in 33 documents. CONCLUSIONS: Most of the definitions defined RWD as data collected in a non-randomized controlled trial setting. A considerable number of definitions, however, diverged from this concept. Moreover, a significant number of authors and stakeholders did not have an official, institutional definition for RWD. Persisting variability in stakeholder definitions of RWD may lead to disparities among different stakeholders when discussing RWD use in decision making.

The effect of neuroendocrine abnormalities on the risk of psychiatric readmission after hospitalization for bipolar disorder: A retrospective study.

BACKGROUND: The correlation between the endocrine system and bipolar disorder(BD) has been well recognized, yet the influence of neuroendocrine hormones on readmission risk post-hospitalization for BD remains largely unexplored. This retrospective cohort study was to scrutinize the impact of neuroendocrine functionality on the readmission of patients with BD post-hospitalization for mental disorders. METHODS: The dataset was derived from the electronic medical records of the First Affiliated Hospital of Jinan University in Guangzhou, China. Both univariate and multivariate logistic regression analysis were conducted on all patients hospitalized for BD, and from 1 January 2017 to October 2022. RESULTS: Of the 1110 eligible patients, 83 and 141 patients experienced psychiatric readmissions within 90 and 180 days post-discharge, respectively. Multivariate analysis revealed that high serum TSH levels (aOR = 1.079; 95%CI = 1.003-1.160) and thyroid disease comorbidities (aOR = 2.899; 95%CI = 1.303-6.452) were independently correlated with the risk of 90-day readmission; while increased serum TSH levels (aOR = 1.179; 95%CI = 1.081-1.287) represented a risk factor for 180-day readmission. These results indicate that high serum TSH levels and thyroid disease comorbidities may contribute to an elevated readmission risk in patients with BD following hospitalization. CONCLUSION: Routinely evaluating and intervening in thyroid function is crucial in the treatment of BD, as it may aid in preventing re-hospitalization.

Ceftazidime-avibactam induced renal disorders: past and present.

With the increasing prevalence of multidrug-resistant Gram-negative bacterial pathogens worldwide, antimicrobial resistance has become a significant public health concern. Ceftazidime-avibactam (CAZ-AVI) exhibited excellent in vitro activity against many carbapenemase-producing pathogens, and was widely used for the treatment of various complicated infections. CAZ-AVI is well tolerated across all dosing regimens, and its associated acute kidney injury (AKI) in phase II/III clinical trials is rare. However, recent real-world studies have demonstrated that CAZ-AVI associated AKI was more frequent in real-world than in phase II and III clinical trials, particularly in patients receiving concomitant nephrotoxic agents, with critically ill patients being at a higher risk. Herein, we reviewed the safety data related to renal impairment of CAZ-AVI, and discussed its pharmacokinetic/pharmacodynamic targets and dosage adjustment in patients with impaired renal function. This review aimed to emphasize the importance for healthcare professionals to be aware of this adverse event of CAZ-AVI and provide practical insights into the dosage optimization in critically ill patients with renal dysfunction.

Molnupiravir Use Among Patients with COVID-19 in Real-World Settings: A Systematic Literature Review.

INTRODUCTION: Molnupiravir (MOV) is an oral antiviral for the treatment of individuals with mild-to-moderate COVID-19 and at high risk of progression to severe disease. Our objective was to conduct a systematic literature review (SLR) of evidence on the effectiveness of MOV in reducing the risk of severe COVID-19 outcomes in real-world outpatient settings. METHODS: The SLR was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines and using pre-determined population, intervention, comparison, outcome, time, and study design inclusion criteria. Eligible studies were published between January 1, 2021, and March 10, 2023, and evaluated the real-world effectiveness of MOV compared to no treatment in reducing the risk of severe COVID-19 outcomes among outpatients ≥ 18 years of age with a laboratory-confirmed diagnosis of SARS-CoV-2 infection. RESULTS: Nine studies from five countries were included in the review. The size of the MOV-treated group ranged from 359 to 7818 individuals. Omicron variants of SARS-CoV-2 were dominant in all study periods. Most studies noted differences in the baseline characteristics of the MOV-treated and untreated control groups, with the treated groups generally being older and with more comorbidities. Eight studies reported that treatment with MOV was associated with a significantly reduced risk of at least one severe COVID-19 outcome in at least one age group, with greater benefits consistently observed among older age groups. CONCLUSIONS: In this SLR study, treatment with MOV was effective in reducing the risk of severe outcomes from COVID-19 caused by Omicron variants, especially for older individuals. Differences in the ages and baseline comorbidities of the MOV-treated and control groups may have led to underestimation of the effectiveness of MOV in many observational studies. Real-world studies published to date thus provide additional evidence supporting the continued benefits of MOV in non-hospitalized adults with COVID-19.

COVID-19 continues to be a major source of morbidity and mortality. Throughout the pandemic, many countries authorized various therapies for the treatment of individuals presenting with mild-to-moderate COVID-19 and at high risk of progression to severe disease. Some of these therapies have since been rendered ineffective due to the emergence of Omicron variants in late 2021. The objective of the current study was to conduct a systematic literature review to assess real-world evidence on the effectiveness of molnupiravir, including effectiveness against COVID-19 caused by Omicron variants, to supplement the findings of the MOVe-OUT clinical trial and further inform on the potential clinical benefit and utility of this antiviral agent. Nine studies were included in the systematic literature review. We found that treatment with molnupiravir was effective in reducing the risk of severe outcomes from COVID-19 caused by Omicron variants, especially for older individuals. Differences in the ages and baseline comorbidities of the molnupiravir-treated and control groups may have led to underestimation of the effectiveness of molnupiravir in many observational studies. In summary, real-world effectiveness studies provide additional evidence supporting the continued benefits of molnupiravir in non-hospitalized adults with COVID-19.

Cabozantinib use in second or subsequent line of treatment in renal cell carcinoma: an analysis of Italian administrative databases.

Background: Cabozantinib use in everyday clinical practice for advanced or metastatic renal cell carcinoma (RCC) is relatively recent, and real-world data on treatment persistence, adherence and sequencing are still limited. Methods: We conducted an analysis based on an integrated administrative database, covering around 6.9 million health-assisted Italian individuals, to explore the use of cabozantinib for RCC. Patients with at least one prescription for cabozantinib during 2017-2020 were searched. These were characterized during all available period (i.e. from 2010 onwards) before the index date and were observed after inclusion. Results: A total of 113 patients treated with cabozantinib in second or subsequent line were included, and their demographic, clinical and treatment characteristics were described. About half of these RCC patients were aged >65 years (47.8%). Sixty patients (53.1%) were highly adherent to cabozantinib therapy, and the median cabozantinib treatment duration of use was 8.7 months (95% confidence interval: 5.8-11.1). During the first year of follow-up, the average total cost per patient was €32,508. Conclusions: We described second or subsequent line cabozantinib treatment for RCC in a real-world setting and the economic burden of disease in Italy, taking advantage of large, integrated administrative databases.
