Utility of a Measure of Lupus Low Disease Activity State (LLDAS) in SLE

This study is a secondary, pooled analysis of two completed phase 3 clinical trials:

(i) GSK-HGS1006-C1056 (BLISS-76): A Phase 3, Multi-Center, Randomized, Double-Blind, Placebo-Controlled, 76-Week Study to Evaluate the Efficacy and Safety of Belimumab (HGS1006, LymphoStat-B™), a Fully Human Monoclonal Anti-BLyS Antibody, in Subjects with Systemic Lupus Erythematosus (SLE); and,

(ii) GSK-HGS1006-C1057 (BLISS-52): A Phase 3, Multi-Center, Randomized, Double-Blind, Placebo-Controlled, 52-Wk Study to Evaluate the Efficacy and Safety of Belimumab (HGS1006, LymphoStat-B™), a Fully Human Monoclonal Anti-BLyS Antibody, in Subjects With Systemic Lupus Erythematosus (SLE)

The study will assess the discriminant validity of a proposed measure of low disease activity (the Lupus Low Disease Activity State, LLDAS) in patients with SLE.

About this study

Systemic Lupus Erythematosus (SLE) is a multisystem autoimmune disease with an estimated incidence of 5-50 cases per 100,000 people. Despite advances in therapy, there is still significant mortality and morbidity associated with this disease. There have been no clearly defined treatment goals in SLE, hindering the development of treat to target approaches and evaluation of new therapies. Although remission is aimed for, it rarely occurs. A more achievable clinical state and treatment goal of low disease activity has been described recently and a preliminary single centre validation study has demonstrated its association with improved outcomes. This endpoint is termed Lupus Low Disease Activity State (LLDAS).

The proposed study will assess the discriminant validity of the proposed LLDAS criteria in a clinical trial dataset. The objective of the research is to validate the Lupus Low Disease Activity State (LLDAS) tool as a study endpoint in SLE. The data available from the belimumab BLISS trials will be used to evaluate the LLDAS score.

The outcome of these studies will be validation of the LLDAS instrument in a clinical trial dataset, for the first time. This will allow future studies to consider incorporating LLDAS attainment as a trial endpoint, for example allowing comparison of frequency of achieving LLDAS to discriminate between treatments.

The findings will be interpreted using statistical methods and will be published / presented to the public and to peers via peer-reviewed publications, conference presentations, and where relevant the lay media.

Treatment and study plan

Primary outcomes

Number of participants who attain the Lupus Low Disease Activity State (LLDAS)

Time frame: 52 weeks

A composite end-point involving SLEDAI-2K ≤4 with no reported renal, central nervous system, cardiopulmonary, vasculitis or gastrointestinal activity and no reported fever, hemolytic anemia or new disease activity since last assessment), SELENA-SLEDAI Physician Global Assessment ≤1, a current prednisolone dose of ≤7.5 mg daily and tolerance of maintenance doses of immunosuppressive drugs and approved biologic agents.

Secondary outcomes

Number of patients achieving a SLE Responder Index (SRI) Response

Time frame: 52 weeks

a ≥ 4 point reduction from baseline in SELENA-SLEDAI score, and no worsening (increase of < 0.30 points from baseline) in PGA, and no new BILAG A organ domain score or 2 new BILAG B organ domain scores compared with baseline.

SELENA SLEDAI is calculated from 24 individual descriptors; 0 indicates inactive disease and the maximum theoretical score is 105; scores > 20 are rare. PGA is a visual analog scale scored from 0 to 3 (1=mild, 2=moderate, 3=severe). BILAG uses a single score for each of the 8 organ domains; range is from severe to no disease (A to E).
