Primary Outcome Measures :
- Percentage of Participants Achieving Systemic Lupus Erythematosus Responder Index (SRI-4) Response at Week 28 [ Time Frame: Week 28 ]The SRI is a composite index used to assess clinical improvement in participants with Systemic Lupus Erythematosus (SLE). The SRI-4 response evaluates global improvement, any significant worsening in unaffected organ systems, and improvements in disease activity, without compromise to the patient's overall condition. SRI-4 response is binary and is either achieved or not achieved by the participant, thus there is no associated score.
- Percentage of Participants Experiencing Adverse Events (AEs) [ Time Frame: Up to approximately 28 weeks ]An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
- Percentage of Participants Discontinuing Study Treatment Due to an AE [ Time Frame: Up to approximately 28 weeks ]An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
Secondary Outcome Measures :
- Percentage of Participants Achieving British Isles Lupus Assessment Group (BILAG)-based Composite Lupus Assessment Response (BICLA) at Week 28 [ Time Frame: Week 28 ]The BICLA response is a composite global measure of SLE disease activity. It distinguishes between partial and complete improvement in all body systems. BICLA response is binary and is either achieved or not achieved by the participant, thus there is no associated score.
- Percentage of Participants Achieving SRI-4 Response at Week 52 [ Time Frame: Week 52 ]The SRI is a composite index used to assess clinical improvement in patients with Systemic Lupus Erythematosus (SLE). The SRI-4 response evaluates global improvement, any significant worsening in unaffected organ systems, and improvements in disease activity, without compromise to the patient's overall condition. SRI-4 response is binary and is either achieved or not achieved by the participant, thus there is no associated score.
- Percentage of Participants Achieving BICLA at Week 52 [ Time Frame: Week 52 ]The BICLA response is a composite global measure of SLE disease activity. It distinguishes between partial and complete improvement in all body systems. BICLA response is binary and is either achieved or not achieved by the participant, thus there is no associated score.
- Percentage of Participants with a Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI)-50 Response at Week 28 [ Time Frame: Week 28 ]The CLASI-A score is used to evaluate lupus skin manifestations. CLASI-A scores of 0 to 9, 10 to 20, and 21 to 70 represent disease severity of mild, moderate, and severe, respectively. CLASI-50 is 50% of improvement from baseline in the CLASI-A score.
- Percentage of Participants with a CLASI-50 Response at Week 52 [ Time Frame: Week 52 ]The CLASI-A score is used to evaluate lupus skin manifestations. CLASI-A scores of 0 to 9, 10 to 20, and 21 to 70 represent disease severity of mild, moderate, and severe, respectively. CLASI-50 is 50% of improvement from baseline in the CLASI-A score.
- Change From Baseline of 28 Joint Count at Week 28 [ Time Frame: Baseline and Week 28 ]The joint count score is an evaluation of 28 joints in which joints are assessed for presence or absence of swelling and presence or absence of tenderness. The number of affected joints may range from 0 to 28; with higher values corresponding to higher disease activity and lower values to better.
- Change From Baseline of 28 Joint Count at Week 52 [ Time Frame: Baseline and Week 52 ]The joint count score is an evaluation of 28 joints in which joints are assessed for presence or absence of swelling and presence or absence of tenderness. The number of affected joints may range from 0 to 28; with higher values corresponding to higher disease activity and lower values to better.
- Change From Baseline of Corticosteroid Dose at Week 28 [ Time Frame: Baseline and Week 28 ]Participants are assessed for corticosteroid dose change.
- Change From Baseline of Corticosteroid Dose at Week 52 [ Time Frame: Baseline and Week 52 ]Participants are assessed for corticosteroid dose change.
- Cumulative Oral Corticosteroid Use Between Week 0 to Week 28 [ Time Frame: Up to approximately 28 weeks ]Participants are assessed for total corticosteroid use.
- Cumulative Oral Corticosteroid Use Between Week 0 to Week 52 [ Time Frame: Up to approximately 52 weeks ]Participants are assessed for total corticosteroid use.
- Percentage of Participants Who Achieve Low Level of Disease Activity (LLDAS) at Week 28 [ Time Frame: Week 28 ]LLDAS is a low disease activity state associated with significant protection against flares and organ damage accrual. It includes both the measurement of disease activity and maintenance of immunosuppressive medications. LLDAS response is binary and is either achieved or not achieved by the participant, thus there is no associated score.
- Percentage of Participants Who Achieve LLDAS at Week 52 [ Time Frame: Week 52 ]LLDAS is a low disease activity state associated with significant protection against flares and organ damage accrual. It includes both the measurement of disease activity and maintenance of immunosuppressive medications. LLDAS response is binary and is either achieved or not achieved by the participant, thus there is no associated score.
