BENLYSTA® Special Drug Use Investigation

BENLYSTA for Intravenous Injection / Subcutaneous Injection Special Drug Use Investigation

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.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	From the start of the study intervention (Day 1) up to maximum of 3 years
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.

From the start of the study intervention (Day 1) up to maximum of 3 years
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.	Baseline (Day 0) and Week 24
Change From Baseline in SELENA SLEDAI Score at Week 52	The SELENA-SLEDAI score is a cumulative and weighted index for assessing systemic lupus erythematosus (SLE) disease activity in participants with SLE.

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.

Total score was derived by adding up scores of all 10 items. Total score ranges from 0 (less impact on daily life) to 40 (greater impact on daily life). Higher score indicates greater impact of lupus on quality of life.	Baseline (Day 0) and Week 24

Total score was derived by adding up scores of all 10 items. Total score ranges from 0 (less impact on daily life) to 40 (greater impact on daily life). Higher score indicates greater impact of lupus on quality of life.	Baseline (Day 0) and Week 52
