TOPLINE:
A greater proportion of patients with active systemic lupus erythematosus (SLE) treated with belimumab plus standard therapy achieved the newest definitions for remission and low disease activity compared with those treated with placebo plus standard therapy, with benefits observed as early as week 28 for remission and week 8 for disease activity, according to pooled results from five clinical trials.
METHODOLOGY:
- Researchers conducted an integrated post hoc analysis of five randomized phase 3 clinical trials to evaluate the attainment of remission and low disease activity in adult patients with active, autoantibody-positive SLE.
- A total of 3086 patients (median age, 36 years; 94% women) were randomly assigned to receive standard therapy with intravenous belimumab 10 mg/kg monthly or subcutaneous belimumab 200 mg weekly (n = 1869) or placebo (n = 1217).
- The proportion of patients who achieved definitions of remission in SLE (DORIS) remission and lupus low disease activity state (LLDAS) by visit up to week 52 was assessed.
- The analysis also evaluated the time taken to achieve sustained (at least two consecutive visits) and maintained (up to week 52) DORIS remission and LLDAS.
TAKEAWAY:
- At week 52, a higher proportion of patients receiving belimumab vs placebo achieved DORIS remission (8% vs 6%; risk ratio [RR], 1.51; P = .0055) and LLDAS (17% vs 10%; RR, 1.74; P < .0001).
- The earliest observed significant benefit of belimumab over placebo in patients with a higher baseline disease activity was at week 20 for DORIS remission (RR, 2.09; P = .043) and at week 16 for LLDAS (RR, 1.46; P = .034), with both maintained through week 52.
- The proportion of patients who attained DORIS remission and LLDAS as early as week 28 and week 8, respectively, was higher in the belimumab group than in the placebo group, with both maintained through week 52.
- Patients on belimumab were more likely to have a sustained and maintained DORIS remission (hazard ratio [HR], 1.53; P = .013) and LLDAS (HR, 1.79; P < .0001) at any timepoint.
IN PRACTICE:
“The data clearly support that belimumab is a valuable addition toward accomplishing and maintaining remission or LLDAS,” George Bertsias, MD, PhD, University of Crete Medical School, Heraklion, Greece, and Jinoos Yazdany, MD, University of California San Francisco, wrote in a related comment.
SOURCE:
This study, led by Ioannis Parodis, MD, Karolinska Institutet and Karolinska University Hospital, Stockholm, Sweden, was published online on August 26, 2024, in The Lancet Rheumatology.
LIMITATIONS:
Due to the post hoc nature of the analysis, the trials were not specifically designed to have adequate statistical power to demonstrate the difference between patients who did or did not achieve DORIS remission or LLDAS. The analysis was limited to patients who met the eligibility criteria, and the outcomes are not generalizable to populations outside a clinical trial setting. The study population had high disease activity, which made it challenging to attain the treatment targets.
DISCLOSURES:
The five trials included in this analysis were funded by GSK. The study was supported by the Swedish Rheumatism Association, King Gustaf V’s 80-year Foundation, the Swedish Society of Medicine, Nyckelfonden, Professor Nanna Svartz Foundation, Ulla and Roland Gustafsson Foundation, Region Stockholm, and Karolinska Institutet. Some authors reported receiving grants, speaker honoraria, or consulting fees from various pharmaceutical companies. Some authors reported being employees and owning stocks and shares of GSK.
