Study summary

The objective of this study is to collect and assess the information about long-term safety and effectiveness of Benlysta for intravenous injection and Benlysta for subcutaneous injection (hereinafter referred to as "Benlysta") in daily clinical practice. The aim of conducting this drug use investigation (DUI) in all subjects until data are accumulated from a certain number of subjects after Benlysta being marketed, data will be collected on safety and effectiveness of Benlysta in an early stage and thereby to take the necessary measures for proper use of Benlysta. Approximately 600 subjects will be enrolled in to this study. The observation period per subject will be 52 weeks from the start of Benlysta administration. BENLYSTA is the registered trademark of GlaxoSmithKline (GSK) group of companies.

What researchers measure

Primary outcomes

  1. Number of Participants With Adverse Drug Reactions (ADRs)

    ADR is defined as a response to a drug which is noxious and unintended, and which occurred at doses normally used in human for the prophylaxis, diagnosis, or therapy of disease, or for the modifications of physiological function.

    Time frame: From the start of the study intervention (Day 1) up to maximum of 3 years

  2. Number of Participants With Serious ADR of Events Defined as a Priority Study Matter

    ADR is defined as a response to a drug which is noxious and unintended, and which occurred at doses normally used in human for the prophylaxis, diagnosis, or therapy of disease, or for the modifications of physiological function. Following serious ADRs were considered as priority study matter: 1. Serious hypersensitivity, 2. Serious infections (including tuberculosis, pneumonia, pneumocystis pneumonia, sepsis, and opportunistic infection), 3. Reactivation of hepatitis B virus, 4. Progressive multifocal leukoencephalopathy, 5. Interstitial pneumonitis, 6. Malignant tumor, 7. Depression and events related to suicide/self-injury.

  3. Change From Baseline in Safety of Estrogens in Lupus Erythematosus National Assessment Systemic Lupus Erythematosus Disease Activity Index (SELENA SLEDAI) Score at Week 24

    The SELENA-SLEDAI score is a cumulative and weighted index for assessing systemic lupus erythematosus (SLE) disease activity in participants with SLE. It consists of 24 disease descriptors related to signs and symptoms, laboratory tests, and physician's assessment across 9 organ systems. Each descriptor is assigned a weighted score (8 descriptors with a weight of 8 each, 6 descriptors with a weight of 4 each, 7 descriptors with a weight of 2 each, and 3 descriptors with a weight of 1 each) which is added up if the descriptor is observed during a visit or within the preceding 10 days. The total score ranges from 0 (no disease activity) to 105 (all 24 descriptors present simultaneously). A higher score indicates a more significant degree of disease activity. Baseline was considered as Day 0 of the study. Change from Baseline was defined as value at the indicated time point minus Baseline value.

    Time frame: Baseline (Day 0) and Week 24

  4. Change From Baseline in SELENA SLEDAI Score at Week 52

Participant flow

This Special Drug Use Investigation was conducted under routine clinical practice in Japan as a non-interventional/observational study. No treatment arms were assigned by protocol; route of administration (intravenous \[IV\] or subcutaneous \[SC\]) was determined by treating physicians in real world care. Protocol confirms observational conduct in actual use conditions and does not define any randomized or assigned arms.

The SELENA-SLEDAI score is a cumulative and weighted index for assessing systemic lupus erythematosus (SLE) disease activity in participants with SLE. It consists of 24 disease descriptors related to signs and symptoms, laboratory tests, and physician's assessment across 9 organ systems. Each descriptor is assigned a weighted score (8 descriptors with a weight of 8 each, 6 descriptors with a weight of 4 each, 7 descriptors with a weight of 2 each, and 3 descriptors with a weight of 1 each) which is added up if the descriptor is observed during a visit or within the preceding 10 days. The total score ranges from 0 (no disease activity) to 105 (all 24 descriptors present simultaneously). A higher score indicates a more significant degree of disease activity. Baseline was considered as Day 0 of the study. Change from Baseline was defined as value at the indicated time point minus Baseline value.

The PGA is used to assess the participant's current disease activity by investigator. It was collected on a 10 centimeter (cm) visual analogue scale (VAS). The score ranges from 0 (no activity) to 3 (severe activity). Lower score means no disease activity, higher score means severe disease activity. Baseline was considered as Day 0 of the study. Change from Baseline was defined as value at the indicated time point minus Baseline value.

PrimaryPercent Change From Baseline in Mean Daily Steroid Dose at Week 4

Mean daily steroid dose was calculated based on the prednisolone equivalent dose. The average dose over the 7 days prior to and including the assessment date was used as mean daily steroid dose. Baseline was considered as Day 0 of the study. Change from Baseline was defined as value at the indicated time point minus Baseline value. Percent change from Baseline was calculated by dividing change from Baseline value by Baseline value and multiplying it by 100.

PrimaryNumber of Participants Who Achieved Lupus Low Disease Activity State (LLDAS) Response Criteria at Week 24

LLDAS was defined as a state which, if sustained, was associated with a low likelihood of adverse outcome, considering disease activity and medication safety. The LLDAS response criteria were: (1) Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) less than equal to (\<=)4 and no major active organ involvement (renal, central nervous system, cardiopulmonary, vasculitis, and pyrexia) and without hemolytic anemia or active gastrointestinal lesions; (2) no new signs or symptoms as compared to the last SELENA-SLEDAI assessment; (3) PGA score \<=1 (33 millimeter); (4) corticosteroid dose \<=7.5 milligram (mg)/day at time of assessment; and (5) use of the same immunosuppressant as compared with prior medication. No unapproved immunosuppressant drugs like rituximab, anifrolumab, ustekinumab, or baricitinib were used as concomitant medications.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2018 to primary completion in Jul 2025, 90 months.

Results were first posted in May 2026, 9 months after primary completion.

Of 112 observational studies under Lupus Erythematosus, Systemic, half reached primary completion within 64 months of starting (the median), counting those still running; a quarter within 34 and three quarters within 126. This study's 90 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 18, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
