Concordance and discordance in SLE clinical trial outcome measures: analysis of three anifrolumab phase 2/3 trials

Ann Rheum Dis 2022;81:962–969 doi: 10.1136/annrheumdis-2021-221847

Bruce, et al. investigate the degree of concordance between BICLA and SRI-4 response across anifrolumab trials (TULIP-1, TULIP-2 and MUSE) in order to better understand drivers of discrepant systemic lupus erythematosus (SLE) trial results.


Indirect treatment comparison of anifrolumab efficacy versus belimumab in adults with systemic lupus erythematosus

J Comp Eff Res. 2022;11(10):765–777 doi: 10.2217/cer-2022-0040

Population-adjusted comparative study provides insights for decision makers and clinicians about the comparative efficacy of anifrolumab and belimumab in patients with moderate-to-severe systemic lupus erythematosus (SLE) who are receiving standard therapy.

In the absence of head-to-head comparisons, Bruce, et al. assessed the comparative efficacy of the two biological therapies currently approved in the EU and USA for the treatment of moderate-to-severe SLE (anifrolumab 300 mg and belimumab 10 mg/kg).

After adjusting for important cross-trial differences, their results showed that anifrolumab was associated with significantly greater treatment benefits than belimumab.


Biological impact of iberdomide in patients with active systemic lupus erythematosus

doi: 10.1136/annrheumdis-2022-222212

Phase 2b study evaluating the pharmacodynamics and pharmacokinetics of oral iberdomide in patients with active SLE demonstrates that iberdomide significantly improves lupus disease activity and reduces hallmarks of the immunopathogenesis of SLE.

Impact of belimumab on organ damage in systemic lupus erythematosus

Arthritis Care Res (Hoboken). 2022 Epub ahead of print doi: 10.1002/acr.24901

Review of clinical trial and real-world data on the effects of belimumab on organ damage in adult patients with SLE shows that belimumab reduces key drivers of organ damage, decreases organ damage progression and, in those with lupus nephritis (LN), decreases renal-related events.


Race, Ethnicity, and Disparities in Risk of End-organ Lupus Manifestations Following SLE Diagnosis in a Multiethnic Cohort

Arthritis Care Res (Hoboken). 2022 Epub ahead of print doi: 10.1002/acr.24892

California Lupus Epidemiology Study (CLUES) finds heightened risks of developing renal, haematologic, and multiorgan disease following SLE diagnosis among Hispanic and Asian patients with SLE.


Major Determinants of Prolonged Remission in Systemic Lupus Erythematosus: Retrospective Study Over a 41+ Year Period

Rheumatology (Oxford). 2022 Epub ahead of print

Retrospective observational study over a 41-year period finds complete remission (CR) in SLE to be associated with Caucasian race, older age at diagnosis, absence of renal involvement and absence of antiphospholipid syndrome.


High Systemic Type I Interferon Activity Is Associated with Active Class III/IV Lupus Nephritis

The Journal of Rheumatology 2022; 49:388–97 DOI 10.3899/jrheum.210391

Iwamoto, et al. aimed to determine the association of serum IFN activity with subtypes of lupus nephritis. This study suggests that systemic high type I IFN in SLE is involved in the pathogenesis of severe class III/IV LN and contributes to severe kidney involvement in European-American patients with SLE. However, this effect was independent of anti‑dsDNA antibody status and complement levels. Expression of type I IFN was not found to be clearly related to plasmacytoid dendritic cell infiltration, although it did directly stimulate podocytes to induce chemokines and molecules related to podocyte injury.


Anifrolumab efficacy and safety by type I interferon gene signature and clinical subgroups in patients with SLE: post hoc analysis of pooled data from two phase III trials

Ann Rheum Dis. 2022; 0:1–11. doi: 10.1136/annrheumdis-2021-221425

IFN-I signalling plays a key role in SLE pathogenesis, and anifrolumab has demonstrated inhibitory effects on IFN-I signalling in patients with SLE. Vital, et al. characterised efficacy and safety of anifrolumab in patients with moderate-to-severe SLE based on interferon gene signature, demographic and clinical subgroups using data pooled from the Phase III TULIP-1 and -2 trials.


Efficacy and Safety of Obinutuzumab in Systemic Lupus Erythematosus Patients with Secondary Non-response to Rituximab

Rheumatology 2022;00:1–5 DOI.org/10.1093/rheumatology/keac150

Arnold, et al. present the first case series reporting the efficacy and safety of obinutuzumab in patients with treatment refractory SLE. The results indicate that, for this group of patients with limited treatment approaches, obinutuzumab could be a potential option.
