Efficacy and safety of biologics, multitarget therapy, and standard therapy for lupus nephritis: a systematic review and network meta-analysis.

OBJECTIVE

This study aimed to compare the efficacy and safety of biologics, multitarget therapy, and standard therapy for the induction of lupus nephritis.

METHODS

A systematic search of electronic databases (EMBASE, Web of Science, PubMed, Cochrane Library, and ClinicalTrials.gov) was conducted from inception to 30 August 2023. Our study included randomized controlled trials enrolling adult lupus nephritis patients treated with biologics or multitarget therapy, in comparison with standard therapy. The primary outcomes were the rates of complete renal remission (CRR) and serious adverse events (SAE). Stata 15.0 was used to conduct the network meta-analysis.

RESULTS

Ten randomized controlled trials with a total of 1989 patients met the inclusion criteria. The network meta-analysis indicated that compared with standard therapy, multitarget therapy, obinutuzumab, belimumab, and voclosporin therapy demonstrated superior efficacy in achieving complete renal remission. Among these options, multitarget therapy had the greatest effect (OR = 2.78, 95% CI = 1.81-4.26). Regarding safety, it was observed that there were no significant statistical differences among the various treatment options. Cluster analysis revealed that both obinutuzumab and belimumab exhibited good efficacy and safety.

CONCLUSIONS

belimumab and obinutuzumab stood out as promising treatments due to their good performance in terms of efficacy and safety. Multitarget therapy may be the most effective approach for treating lupus nephritis. However, since the study population consists exclusively of Asian patients, further research is needed to verify the efficacy of multitarget therapy in lupus nephritis patients of non-Asian descent.
