Primary Outcome Measures
NameTimeMethod
Systemic Lupus Erythematosus Responder Index (SRI)-4 Response at Week 48Week 48

The Systemic Lupus Erythematosus Responder Index (SRI)-4 measures reduction in SLE disease activity and is a composite measure that includes the SLE Disease Activity Index (SLEDAI-2K), British Isles Lupus Activity Group (BILAG) 2004 and Physician Global Assessment. It is defined as: 1) Reduction of ≥4 points from baseline in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score; 2) no new British Isles Lupus Assessment Group (BILAG) A or no more than 1 new BILAG B disease activity scores and 3) no worsening (defined as an increase of ≥0.3 points \[10 mm\] from baseline) in the Physician's Global Assessment of Disease Activity. The score range is from 0 to 100, with higher scores indicating greater disease activity.

Secondary Outcome Measures
NameTimeMethod
SRI-4 Response at Week 24 With a Sustained Reduction of OCS Dose to < 10 mg/Day and </= Day 1 Dose During Week 12 Through Week 24Week 24

The SRI-4 measures reduction in SLE disease activity and is a composite measure that includes the SLE Disease Activity Index (SLEDAI-2K), British Isles Lupus Activity Group (BILAG) 2004 and Physician Global Assessment. It is defined as: 1) Reduction of ≥4 points from baseline in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score; 2) no new British Isles Lupus Assessment Group (BILAG) A or no more than 1 new BILAG B disease activity scores and 3) no worsening (defined as an increase of ≥0.3 points \[10 mm\] from baseline) in the Physician's Global Assessment of Disease Activity. The score range is from 0 to 100, with higher scores indicating greater disease activity. OCS tapering requires a sustained reduction of OCS from Week 12 through Week 24 \[less than 10 milligram per day (mg/day) and less or equal to the dose received on Day 1\].

The score range is from 0 to 100, with higher scores indicating greater disease activity.

SRI-4 Response at Week 48 in Patients With High vs. Low Plasmablast Signature LevelsWeek 48

The SRI-4 measures reduction in SLE disease activity and is a composite measure that includes the SLE Disease Activity Index (SLEDAI-2K), British Isles Lupus Activity Group (BILAG) 2004 and Physician Global Assessment.

The score range is from 0 to 100, with higher scores indicating greater disease activity. The Plasmablast Signature (PB) is a Bruton's Tyrosine Kinase (BTK)-dependent blood RNA signature comprised of three genes (IgJ, MZB1 and TXNDC5). Q1/2/3/4 = Quartile 1/2/3/4.

Percentage of Participants With Adverse Events (AEs)Baseline up to 8 weeks after the last dose of study drug (up to Week 56).

An Adverse Event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

Plasma Concentrations of Fenebrutinib at Specified TimepointsBaseline (Pre-dose), Week 24 (Pre-dose and Post-dose) and Week 48 (Pre-dose)

The PK analyses includes tabulation of plasma concentration data and summarisation of plasma concentrations by visits with participants grouped according to treatment received. Descriptive summary statistics for the Arithmetic Mean and Standard Deviation are presented below.

BILAG-based Composite Lupus Assessment (BICLA) Response at Week 24 and 48Week 24, 48

The BICLA is a composite index that is defined as follows: \[1\] At least one gradation of improvement in baseline BILAG scores in all body systems with moderate or severe disease activity at entry (e.g., all A (severe disease) scores falling to B (moderate), C (mild), or D (no activity) and all B scores falling to C or D; \[2\] No new BILAG A or more than one new BILAG B scores; \[3\] No worsening of total SLEDAI-2K score from baseline; \[4\] No significant deterioration (=\<10%) in physician's global assessment and \[5\] No treatment failure (initiation of non-protocol treatment).

SRI-6 Response at Week 24 and 48Week 24, 48

The Systemic Lupus Erythematosus Responder Index (SRI)-6 measures reduction in SLE disease activity and is a composite measure that includes the SLE Disease Activity Index (SLEDAI-2K), British Isles Lupus Activity Group (BILAG) 2004 and Physician Global Assessment. It is defined as: 1) Reduction of ≥6 points from baseline in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score; 2) no new British Isles Lupus Assessment Group (BILAG) A or no more than 1 new BILAG B disease activity scores and 3) no worsening (defined as an increase of ≥0.3 points \[10 mm\] from baseline) in the Physician's Global Assessment of Disease Activity. The score range is from 0 to 100, with higher scores indicating greater disease activity.
