Efficacy and Safety of Avatrombopag in Patients With Thrombocytopenia: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: Background: Avatrombopag is a novel oral, nonpeptide thrombopoietin receptor agonist (TPO-RA). A few studies have shown that avatrombopag is effective against thrombocytopenia. However, no systematic review has been conducted on the efficacy and safety of avatrombopag. Therefore, the aim of this study was to comprehensively assess the efficacy and safety of avatrombopag patients with thrombocytopenia. Methods: Databases including Medline, PubMed, Embase, the Cochrane Library and ClinicalTrials.gov were searched for randomized controlled trials that compared avatrombopag with placebo in patients with thrombocytopenia. The deadline was March 2019. Results: In total, 743 patients were analyzed in five clinical trials. Patients treated with avatrombopag achieved higher platelet response (OR: 17.71, 95% CI [11.01 to 28.48], p < 0.00001) than with placebo. Avatrombopag produced an absolute increment in platelet count (WMD: 31.13%, 95% CI [22.27 to 39.99], p < 0.00001) unlike the placebo. In addition, the incidence of serious adverse events (RR: 1.18, 95% CI [0.72 to 1.93], p = 0.51) and deaths (RR: 0.93, 95% CI [0.19 to 4.45], p = 0.93) in patients treated with avatrombopag was not significantly different from that in patients treated with placebo. The incidence of adverse events in patients treated with avatrombopag was slightly higher than that in patients treated with placebo (RR: 1.25, 95% CI [1.05 to 1.49], p = 0. 01) after one trial with high heterogeneity was removed. Conclusions: This meta-analysis showed that avatrombopag was an effective treatment for thrombocytopenia, but there is sufficient evidence to indicate that adverse events may occur.

Project description:IntroductionA network meta-analysis (NMA) was performed to assess the efficacy and safety of avatrombopag, relative to eltrombopag, romiplostim, and fostamatinib, for patients with chronic immune thrombocytopenia (ITP) not responding adequately to corticosteroids.MethodsA systematic search of publication and clinical trial databases was conducted to identify relevant randomized controlled trials (RCTs) and observational studies. Data from eligible studies were extracted and analyzed in a Bayesian framework using relative effect sizes vs placebo. Outcomes included durable platelet response; need for rescue therapy; reduction in use of concomitant ITP medication; incidence of any or World Health Organization (WHO) grade 2-4 bleeding events, and any adverse events. Results were reported as odds ratios or incidence rate ratios (IRR) with 95% credible intervals (CrIs).ResultsThe NMA included seven phase 3 RCTs. Compared with placebo, avatrombopag was associated with statistically significant improvements in durable platelet response, reduction in use of concomitant ITP medication, and incidence of any bleeding events. Statistically significant differences vs placebo were also observed for durable platelet response and need for rescue therapy (eltrombopag, romiplostim, and fostamatinib); reduction in use of concomitant ITP medication (eltrombopag and romiplostim); incidence of any bleeding events (fostamatinib); and incidence of WHO grade 2-4 bleeding events (romiplostim and fostamatinib). No statistically significant differences were observed for any adverse events. Avatrombopag was associated with a statistically significant lower incidence of any bleeding events vs eltrombopag (IRR 0.38 [95% CrI 0.19, 0.75]) and romiplostim (IRR 0.38 [95% Crl 0.17, 0.86]); no other between-treatment differences were observed.ConclusionIn this NMA, avatrombopag significantly increased the chance of achieving durable platelet response and reducing the use of concomitant ITP medication vs placebo, and significantly reduced the incidence of any bleeding events compared with placebo, eltrombopag, and romiplostim. The study aims to help guide clinicians managing patients with chronic ITP and insufficient response to previous treatment.

Project description:BackgroundFibromyalgia is a chronic pain syndrome characterized by persistent and widespread musculoskeletal pain. Telerehabilitation is a promising treatment for patients with fibromyalgia through long-term monitoring, intervention, supervision, consultation, and education.ObjectiveThis study aimed to perform a comprehensive systematic review and meta-analysis of the efficacy and safety of telerehabilitation in patients with fibromyalgia.MethodsRandomized controlled trials (RCTs) related to fibromyalgia and telerehabilitation were systematically searched in the PubMed, PEDro, Cochrane Library, ScienceDirect, Ovid MEDLINE, Embase, and Web of Science databases from inception to November 13, 2022. Two independent researchers screened the literatures and evaluated the methodological quality using the Cochrane Risk of Bias Tool. The outcome measures included the Fibromyalgia Impact Questionnaire scale, pain intensity, depression, pain catastrophizing, quality of life (QoL), and adverse events. Pooled effect sizes were calculated by Stata SE 15.1; a fixed effects model was used when I2<50%, whereas a random effects model was used when I2≥50%.ResultsA total of 14 RCTs with 1242 participants were included in this meta-analysis. The pooled results indicated that the telerehabilitation improved the Fibromyalgia Impact Questionnaire score (weighted mean difference -8.32, 95% CI -11.72 to -4.91; P<.001), pain intensity (standardized mean difference [SMD] -0.62, 95% CI -0.76 to -0.47; P<.001), depression levels (SMD -0.42, 95% CI -0.62 to -0.22; P<.001), pain catastrophizing (weighted mean difference -5.81, 95% CI -9.40 to -2.23; P=.001), and QoL (SMD 0.32, 95% CI 0.18 to 0.47; P<.001) in patients with fibromyalgia compared to control interventions. Only 1 RCT reported a mild adverse event of telerehabilitation; the other 13 RCTs did not mention this.ConclusionsTelerehabilitation can improve the symptoms and QoL of fibromyalgia. However, the safety of telerehabilitation remains uncertain due to the lack of sufficient evidence for the management of fibromyalgia. More rigorously designed trials are needed in the future to verify the safety and efficacy of telerehabilitation in fibromyalgia.Trial registrationPROSPERO CRD42022338200; https://tinyurl.com/322keukv.

Project description:IntroductionRett syndrome is a rare genetic neurodevelopmental disorder that predominantly impacts females. It presents with loss of acquired skills, impaired communication, and stereotypic hand movements. Given the limited treatment options for Rett syndrome, there is a dire need for effective interventions.ObjectiveTo evaluate the safety and efficacy of trofinetide in Randomized Controlled Trials (RCTs) that report on Rett syndrome patients.MethodsWe identified 109 articles from four databases (Scopus, PubMed, Web of Science, and Cochrane CENTRAL). After removing the duplicates, we narrowed them down to 59 articles for further assessment. We included RCTs that evaluated the efficacy and safety of trofinetide in patients with Rett syndrome. Three studies were eligible for inclusion. Two independent reviewers evaluated the identified studies' titles, abstracts, and full texts, extracting pertinent data. We assessed the quality of the studies using the Cochrane Risk of Bias (RoB) 2.0 tool. We then conducted a meta-analysis using the fixed effects model in the case of insignificant heterogeneity; otherwise, we used the random effects model. Based on the nature of the outcome, we analyzed the mean difference or the odds ratio. Analysis was conducted using RevMan version 5.3.ResultsAmong the analyzed outcomes in 181 patients in the trofinetide group and 134 patients in the placebo group, significant improvement in Rett Syndrome Behavior Questionnaire (RSBQ) scores was observed at 200 mg dosage (overall mean difference: -3.53, p = 0.001). Clinical Global Impression-Improvement (CGI-I) scores improved considerably at 200 mg dosage (overall mean difference: -0.34, p < 0.0001). No substantial changes were observed in Motor Behavioral Assessment (MBA) or Top 3 Caregiver Concerns. We evaluated Treatment Emergent Adverse Events (TEAEs) across the various dosages and noted significant associations with diarrhea (200 mg), vomiting (200 mg), and irritability (200 mg). However, we did not find a significant association between any of the dosages and the incidence of decreased appetite.ConclusionTrofinetide demonstrated potential in improving RSBQ and CGI-I scores at 200 mg dosage. Although no substantial changes were found in MBA and top 3 caregiver concerns. Adverse events were linked to specific dosages.

Project description:BackgroundAdalimumab is used as a first-line biologic agent in the management of moderate-to-severe hidradenitis suppurativa (HS). The objective of the present study was to evaluate the efficacy and safety of adalimumab in patients with moderate-to-severe HS.MethodsWe performed a systematic review and meta-analysis according to Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines. Pooled estimates, namely standardized mean difference (SMD) and relative risk (RR), were calculated using random-effect model with trial sequential analysis. Small study effects were examined using the Doi plot. Certainty of evidence (CoE) was assessed using "The Grading of Recommendations Assessment, Development, and Evaluation" approach, and number-needed-to-treat (NNT) was calculated.ResultsFive randomized controlled trials, involving 1014 patients, were included. We performed subgroup analysis of adalimumab administered subcutaneously both weekly and every other week. Adalimumab administered weekly was associated with better clinical response achievement (RR 1.76, 95% confidence interval [95% CI] 1.35-2.29; trial sequential analysis TSA-adjusted CI 1.01-3.08; CoE: low; NNT = 5) and a significant improvement in modified Sartorius score (SMD = -0.45, 95% CI = -0.76 to -0.13; CoE: very low; NNT = 10) and dermatology life quality index (DLQI) (SMD -0.47, 95% CI -0.61 to -0.32; CoE: low; NNT = 10). Nevertheless, adalimumab administered every other week showed an improvement only in modified Sartorius score. The pooled RRs of adverse events in both groups revealed no statistical significance when compared with the placebo.ConclusionsAdalimumab administered weekly resulted in not only better clinical responses than placebo but also significantly improved disease severity and quality of life of patients with moderate-to-severe HS. Our study provides supporting evidence to the current guidelines and aids decision-making in the application of adalimumab in HS management.
