Comparative Efficacy and Safety of Biological Agents in the Treatment of Lupus Nephritis: A Network Meta-Analysis.

ABSTRACT:

Background

To date, no studies have described randomized controlled trials (RCTs) evaluating the effectiveness and safety of various biological agents used in induction therapy for lupus nephritis.

Objectives

We designed this study to assess the relative efficacy and safety of some of these biological agents in patients with lupus nephritis.

Method

We collected data from RCTs that examined the efficacy and safety of any biological agents for lupus nephritis and then used these data to complete a Bayesian network meta-analysis to combine the direct and indirect evidence from these studies.

Results

We identified nine RCTs evaluating rituximab, abatacept, belimumab, anifrolumab, obinutuzumab, ocrelizumab, and low-dose interleukin-2 (IL-2) across 1,480 patients. Low-dose IL-2, obinutuzumab, rituximab, and belimumab achieved complete remission in a significant proportion of respondents when compared with that in the control. Ranking probability based on the surface under the cumulative ranking curve (SUCRA) indicated that low-dose IL-2 had the highest probability of achieving complete remission, followed by obinutuzumab, rituximab, belimumab, anifrolumab, abatacept, ocrelizumab, and the control. The risk of serious adverse events (SAE) tended to be lower for low-dose IL-2, rituximab, belimumab, and obinutuzumab than for the control. SUCRA-based ranking indicated that IL-2 had the highest probability of being safe, followed by rituximab, belimumab, obinutuzumab, control, anifrolumab, abatacept, and ocrelizumab.

Conclusions

Low-dose IL-2 was the most effective induction treatment for patients with lupus nephritis and had the lowest potential for SAE. Higher complete remission rates and a more favorable safety profile suggest that low-dose IL-2, obinutuzumab, rituximab, and belimumab may be superior to the current control as treatments for lupus nephritis.

Project description:IntroductionVarious immunosuppressive regimens have been developed for the treatment of lupus nephritis (LN). This study aimed to compare the efficacy and safety of immunosuppressive regimens in adults with LN.MethodsWe systematically searched the PubMed, Embase, and Cochrane Central Register of Controlled Trials databases, including conference proceedings, trial registries, and reference lists, from inception until July 10, 2022. The effects of treatment were compared and ranked using the surface under the cumulative ranking curve (SUCRA). The primary endpoint was total remission. The secondary endpoints were complete remission, systemic lupus erythematosus disease activity index (SLEDAI), relapse, all-cause mortality, end-stage renal disease (ESRD), infection, herpes zoster, ovarian failure, myelosuppression, and cancer.ResultsSixty-two trials reported in 172 studies involving 6,936 patients were included in the network meta-analysis. The combination of tacrolimus (TAC), mycophenolate mofetil (MMF), and glucocorticoid (GC) provided the best result for the total remission rate (SUCRA, 86.63%) and SLEDAI (SUCRA, 91.00%), while the combination of voclosporin (VCS) , MMF and GC gave the best improvement in the complete remission rate (SUCRA, 90.71%). The combination of cyclophosphamide (CYC), MMF and GC was associated with the lowest risk of relapse (SUCRA, 85.57%) and cancer (SUCRA, 85.14%), while the combination of obinutuzumab (OTB), MMF and GC was associated with the lowest risk of all-cause mortality (SUCRA, 84.07%). Rituximab (RTX) plus MMF plus GC was associated with the lowest risk of ESRD (SUCRA, 83.11%), while the risk of infection was lowest in patients treated with azathioprine (AZA) plus CYC plus GC (SUCRA, 68.59%). TAC plus GC was associated with the lowest risk of herpes zoster (SUCRA, 87.67%) and ovarian failure (SUCRA, 73.60%). Cyclosporine (CsA) plus GC was associated with the lowest risk of myelosuppression (SUCRA, 79.50%), while AZA plus GC was associated with the highest risk of myelosuppression (SUCRA, 16.25%).DiscussionThis study showed that a combination of TAC, MMF and GC was the best regimen for improving the total remission rate. The optimal regimen for specific outcomes should be highlighted for high-risk patients.

Project description:BackgroundTo determine the safety and efficacy of biological agents used in the treatment of systemic lupus erythematosus (SLE) in adults.MethodsSystematic review and meta-analysis following PRISMA guidelines.Data sourcesMEDLINE (through Pubmed), EMBASE, Cochrane library, Clinicaltrials.gov, Australianclinicaltrials.gov.au, ANZCTR.org.au and WHO International Clinical Trials Registry Platform for studies published from 20 May 2021 and 15 years prior. A grey literature search was performed and completed on 31 May 2021.Study criteriaPhase II, III or quasi randomised controlled trials, studies with only cerebral or cutaneous lupus were excluded.Data extractionTwo authors independently screened studies for eligibility, extracted, reviewed data for accuracy, and used the Cochrane tool to assess risk of bias.ResultsForty-four studies were identified, consisting of 15 groups of drugs and 25 different biological agents, totalling 16,889 patients. The main outcomes assessed included Systemic Lupus Erythematosus Responder Index (SRI), BILAG-Based Composite Lupus Assessment (BICLA) and combined combined/partial renal remission (CRR/PRR). Four groups of biologics were found to improve outcomes. Anti-interferons: Anifrolumab increased BICLA response and SRI 5 to 8, decreased prednisone dosages, with increased herpes zoster infections, but fewer serious adverse events. Sifalimumab improved SRI but also increased herpes zoster infections. Anti BAFF/BLyS and/or APRIL: Belimumab consistently improved SRI 4, decreased prednisone dosages, increased combined CRR/PRR, and had no adverse safety outcomes. Tabalumab increased SRI 5 at 52 weeks with no steroid sparing effect but was associated with increased infusion related adverse events. Telitacicept improved SRI 4 at 52 weeks, with no increased adverse events, though data was rather sparse. Anti CD-20 monoclonal antibody, Obinutuzumab increased combined CRR/PRR at 1 and 2 years. Anti IL12/23 monoclonal antibody, Ustekinumab, increased SRI 4 to 6, but not BICLA at 24 weeks, with no concerning safety outcomes.ConclusionMultiple biologic agents are shown in high quality studies to have a significant therapeutic impact on outcomes in SLE.

Project description:BackgroundThrombolytic agents and anticoagulants are the two classes of medication used in the treatment of acute pulmonary embolism (PE). There is continuous renewal and iteration of thrombolytic agents, and the efficacy and adverse effects of different agents have different effects on PE due to their different mechanisms of action.ObjectivesThe aim of the study was to evaluate the efficacy and safety of different thrombolytic agents in the treatment of all types of acute PE: hemodynamically unstable PE (massive PE) and hemodynamically stable PE (submassive PE and low-risk PE), using a network meta-analysis.MethodsA search was conducted of the following databases: PubMed, The Cochrane Library, Embase, and Web of Science to collect randomized controlled trials (RCTs) comparing thrombolytic agents with heparin or other thrombolytic agents in patients with acute PE; the clinical outcomes included patient mortality, recurrent PE, pulmonary artery systolic pressure (PASP) after treatment, and major and minor bleeding. The measurement duration of outcome indicators was the longest follow-up period. Thereafter, a network meta-analysis was performed using a Bayesian network framework.ResultsA total of 29 RCTs (3,067 patients) were included, of which 6 studies (304 patients) were massive PE, 14 studies (2,173 patients) were submassive PE, 1 study (83 patients) included massive and submassive PE, and 8 studies (507 patients) were PE of unknown type. The treatment regimens included thrombolytic therapy (alteplase, reteplase, tenecteplase, streptokinase, and urokinase) and anticoagulant therapy alone. The results showed that the mortality using thrombolytic agents (except tenecteplase) was significantly lower compared with heparin. The recurrence of PE with alteplase was significantly lower compared with heparin (RR = 0.23, 95% CI, 0.04, 0.65). The PASP after using alteplase was significantly lower compared with heparin (mean difference = -11.36, 95% CI, -21.45, -1.56). Compared with heparin, the incidence of minor bleeding associated with tenecteplase was higher (RR = 3.27, 95% CI, 1.36, 7.39); compared with streptokinase, the incidence of minor bleeding associated with tenecteplase was higher (RR = 3.22, 95% CI, 1.01, 11.10).ConclusionFor patients with acute PE, four thrombolytic agents (alteplase, reteplase, streptokinase, and urokinase) appeared to be superior in efficacy compared with anticoagulants alone due to a reduction in mortality and no increase in bleeding risk. Alteplase may be a better choice because it not only reduced mortality but also reduced PE recurrence rate and treated PASP. Tenecteplase did not reduce mortality compared with anticoagulants alone and may not be a good choice of thrombolytic agent due to an increase in minor bleeding compared with streptokinase and anticoagulants alone. Thrombolytic drugs should be rationally selected to optimize the thrombolytic regimen and achieve as good a balance as possible between thrombolysis and bleeding.

Project description:BackgroundPrevious studies comparing the efficacy and safety of different treatment regimens for lupus nephritis are scarce. Moreover, confounding factors such as the duration of follow-up were hardly adjusted in those studies, potentially compromising the results and their extents to clinical settings.ObjectiveTo rigorously investigate the efficacy and safety of biologics in patients with lupus nephritis using Bayesian network meta-regression analyses that adjust for the follow-up period, in order to provide more robust evidence for clinicians.MethodsDatabases comprising PubMed, Embase, MedlinePlus, Cochrane Library, Google Scholars, and Scopus were retrieved for eligible articles from inception to February 29, 2024. The primary endpoint was the complete response rate, the secondary endpoint was the partial response rate, the tertiary endpoints were the adverse events, and infection-related adverse events. Napierian Logarithm of hazard ratio (lnHR) and the standard error of lnHR (selnHR) were generated for dichotomous variants by STATA 18.0 MP and then put into Rstudio 4.3.2 to conduct Bayesian network meta-analysis as well as network meta-regression analysis to yield hazard ratio (HR) as pairwise effect size.ResultsTen studies involving 2138 patients and 11 treatment regimens were ultimately included. In the original analysis, for the primary endpoint, compared to the control group, obinutuzumab (22.6 months), abatacept-30mg (20.5 months), abatacept-10mg (17.8 months), and belimumab (23.3 months) demonstrated significant superiority (HR ranged from 1.6 to 2.5), more ever, their significance regarding relative efficacy was correlated with follow up period, namely "time window" (shown in parentheses above). For the secondary endpoint, compared to the control group, obinutuzumab and abatacept-30mg showed conspicuous preponderance (HR ranged from 1.6 to 2.4), "time window" was also detected in abatacept-30mg (20.5 months), whereas obinutuzumab remained consistently obviously effective regardless of the follow-up period (shown in parentheses above). For the tertiary endpoint, there were no differences among active regimens and control.ConclusionsConsidering the efficacy and safety and "time window" phenomenon, we recommend obinutuzumab as the preferred treatment for LN. Certainly, more rigorous head-to-head clinical trials are warranted to validate those findings.

Project description:ObjectiveTo evaluate the clinical efficacy and safety of leflunomide as a new immunosuppressive medicine in lupus nephritis (LN) through a meta-analysis.MethodsA systematic review evaluating the efficacy and safety of leflunomide compared with cyclophosphamide in adult patients with LN was performed. Data from relevant randomized controlled trials (RCTs) performed before December 2014 was collected from several databases (PubMed, Embase, Cochrane Library, CNKI and CBM). No language restrictions were applied. Efficacy outcomes included overall remission, SLE Disease Activity Index (SLEDAI) score, 24-hour proteinuria and serum creatinine. Safety data were analyzed. The effects of treatment on these outcomes were summarized as relative risks (RRs) with 95% confidence intervals (CIs) and mean differences were pooled using a fixed or random effects model.ResultsEleven RCTs with Jadad score of 3 or greater were identified and included a total of 254 patients. Cyclophosphamide was served as the control drug in all trials. The SLEDAI score, urine protein level and serum creatinine decreased significantly following leflunomide treatment (P<0.05). Leflunomide was superior to cyclophosphamide in achieving complete and total remission, but no difference in SLEDAI score was found between these two treatments (P>0.05). Additionally, patients receiving leflunomide treatment showed favorable renal function profiles, especially regarding the 24-hour proteinuria (mean difference: -0.58, 95%CI: -0.78~-0.37, P<0.01) and serum creatinine (mean difference: -0.20, 95%CI: -0.39~-0.01, P<0.05). In the safety comparison, leflunomide was safer than cyclophosphamide regarding adverse drug reactions (ADRs), including liver damage (RR = 0.53, 95%CI: 0.33~0.87, P<0.05), alopecia (RR = 0.38, 95%CI: 0.17~0.85, P<0.05), leukopenia (RR = 0.25, 95%CI: 0.08~0.77, P<0.05) and infection (RR = 0.54, 95%CI: 0.32~0.92, P<0.05), without increased risk of gastrointestinal reaction, rash or herpes zoster infection.ConclusionsLeflunomide is a promising therapy for LN treatment, primarily because of the comparable efficacy and favorable safety profile determined by this meta-analysis of RCTs. Larger RCTs with longer duration of observation are necessary to provide strong evidence of the efficacy and safety of leflunomide in LN patients.

Project description:Although telitacicept is a promising drug for treating systemic lupus erythematosus, there are limited studies on its efficacy and safety in patients with lupus nephritis in China. This lack of research data restricts its potential for broader application and acceptance on a global scale. The present study aimed to determine the efficacy and safety of telitacicept in patients with lupus nephritis (LN) in China. Using a self-controlled before-after comparison method, patients with LN were recruited at Lishui Central Hospital between February 2022 and April 2023, who received telitacicept weekly as part of the standard treatment. Data on the systemic lupus erythematosus disease activity index 2000 (SLEDAI-2K), glucocorticoid dosing and the quantity of immunosuppressive medicines prescribed was collected. Additionally, serum complements, erythrocyte sedimentation rate (ESR), urinary protein levels, immunoglobulin concentrations, serum creatinine levels, plasma albumin concentrations, platelet counts and renal function parameters were documented throughout the study. A total of 13 patients were enrolled in the trial, comprising 11 women and two men. Following 12-48 weeks of treatment with telitacicept (80 or 160 mg per week), 84.6% (n=11) of all patients experienced symptom relief and their SLEDAI-2K score was reduced by more than four points. By the observation endpoint, the median glucocorticoid dosage of the 13 patients was decreased from 15 to 2.5 mg/d, and six patients discontinued their glucocorticoids. Furthermore, 46.1% of patients (n=6) reduced their dose and number of immunosuppressive medicines, while 15.4% (n=2) stopped their immunosuppressive medicines. Minimal changes were observed in serum creatinine, platelet count, C3 levels and C4 levels among patients. Immunoglobulin levels (IgG, IgA and IgM) remained stable or showed an upward trend. Plasma albumin levels remained within the normal range in three patients and increased in ten patients. It increased to the normal range in three of these ten patients. At the endpoint, ESR levels decreased in all patients. Additionally, three patients displayed varying degrees of renal function improvement, and their estimated glomerular filtration rate (ml/min/l.73 m2) increased from 127.8 to 134.2, 95.1 to 123.1 and 61.5 to 67.3, respectively. Urinary protein levels decreased in all patients. It decreased >0.5 g/l in seven patients and reached the normal levels in three patients. The adverse events of telitacicept were manageable. Among the patients infected with COVID-19, three patients had fever, 10 patients remained asymptomatic and none of them exhibited severe respiratory syndromes. In this study, telitacicept effectively stabilized LN activity and alleviated the clinical symptoms of most patients. Furthermore, it reduced the dose of glucocorticoid and immunosuppressive medicines. Therefore, telitacicept may be a promising treatment option for individuals with lupus nephritis.

Project description:ObjectivesTo evaluate the effectiveness and safety of different B cell-targeting biological agents combining with standard of care in patients with lupus nephritis (LN).MethodsComprehensive literature searches were conducted using PubMed, Embase, Web of Science, and Central in the Cochran Library, spanning from inception to May 20th, 2024. Randomized control trials (RCTs) comparing rituximab (RTX), belimumab, ocrelizumab, obinutuzumab, and anifrolumab in LN were selected. The primary outcomes of interest were related to complete renal remission (CRR), and partial renal remission (PRR). Additionally, we delved into safety outcomes, examining the occurrence of serious adverse events (SAEs), infections, and the discontinuation rates due to adverse events.ResultsA total of 6 RCTs with 1150 patients applying various B cell-targeting biological agents were included. Notably, ranking probability based on the surface under the cumulative ranking curve (SUCRA) indicated that obinutuzumab (SUCRA 85.2%) has the highest potential superiority in improving CRR, followed by belimumab, ocrelizumab. Regarding the improvement in PRR, obinutuzumab (SUCRA 83.0%) has the highest potential superiority. In terms of safety, with a focus on SAEs, infections, and the discontinuation rates due to adverse events, the results were: SUCRA-based ranking indicated that RTX (SUCRA 74.1%) had the highest probability of postponing SAEs, followed by belimumab and obinutuzumab. Concerning infection reduction, anifrolumab (SUCRA 78.7%) had the highest potential superiority. Safety events monitoring infection occurred better with RTX than with standard therapy (OR = 3.57, 95% CI 1.02, 12.66) and were statistically different. For the discontinuation rates due to adverse events, RTX (SUCRA 88.6%) demonstrated the highest potential superiority.ConclusionsConcerning the effectiveness and safety outcomes, obinutuzumab, belimumab, and RTX plus standard of care may be superior to the current standard therapy as treatments for LN. This study protocol has been registered with PROSPERO, with a registration number of CRD42024548522.
