Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Participants with Treatment Emergent Adverse Events (TEAEs) | Up to Week 284 | An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. A TEAE is an AE that started or worsened in severity after the first dose of study treatment through 28 days after the last dose of study treatment or end of study (EOS) date, whichever comes earlier. |
| Primary | Number of Participants with Serious Adverse Events (SAEs) | Up to Week 284 | An SAE is any untoward medical occurrence that at any dose results in death, in the view of the Investigator, places the participant at immediate risk of death (a life threatening event), requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, results in a congenital anomaly/birth defect, and is a medically important event. |
| Secondary | Percentage of Participants who Achieved an Systemic Lupus Erythematosus Responder Index (SRI)-4 Response | Up to Week 284 | SRI-4 is a composite endpoint defined as the following: * A reduction from baseline of ≥4 points in Systemic Lupus Erythematosus Disease Activity Index (SLEDAI-2K) score. * No new organ system affected, as defined by no new British Isles Lupus Activity Group-2004 (BILAG-2004 grade A) and no more than 1 new BILAG 2004 grade B versus previous visit. * No worsening from baseline in lupus disease activity as defined by \<0.3-point increase on 3-point Physician's Global Assessment (PGA) visual analog scale (VAS). * No violation of protocol-specified medication rules |
| Secondary | Percentage of Participants With at Least 4 Joints (Both Swollen and Tender) at Baseline who Achieved a Joint-50 Response | Up to Week 284 | Joint-50 response is a 50% reduction in total active joint count from baseline. An active joint is defined as a joint with pain and signs of inflammation (e.g., tenderness, swelling or effusion). A 28-joint assessment will be performed to determine the active joint count, which is defined as the sum of tender and swollen joint counts. |
| Secondary | Percentage of Participants With a Cutaneous Lupus Erythematosus Disease Area and Severity Index - Activity (CLASI-A) Score ≥10 at Baseline who Achieved a CLASI-50, CLASI-70, and CLASI-90 Response | Up to Week 284 | CLASI score is used to evaluate lupus skin manifestations. The activity scale (CLASI-A) includes measurements of erythema, scale and hypertrophy, and mucous membrane disease. Each part of the body is listed separately, from the scalp to the feet, in addition to sections focusing on mucous membrane involvement and alopecia. Points are given for the presence of erythema, scale, mucous membrane lesions, recent hair loss, and inflammatory alopecia. Scores for each area are assigned based on the most severe lesion within the area of interest. 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, CLASI-70, and CLASI-90 responders are defined as ≥ 50%, ≥ 70%, and ≥ 90% improvement in CLASI-A score from baseline at the specified timepoint. |
| Secondary | Percentage of Participants who Achieved a British Isles Lupus Assessment Group based Composite Lupus Assessment (BICLA) Response | Up to Week 260 | BICLA is a composite endpoint defined as the following: * BILAG-2004 improvement, defined as all of BILAG-2004 Grade A at baseline improved to B, C, or D and all of BILAG-2004 Grade B at baseline improved to C or D. * No BILAG-2004 worsening in other BILAG-2004 organ systems such that there are no new BILAG-2004 Grade A or greater than 1 new BILAG-2004 Grade B. * No worsening in the SLEDAI-2K total score compared to baseline. * No worsening from baseline in lupus disease activity as defined by \<0.3-point increase on 3-point PGA VAS. * No violation of protocol-specified medication rules. |
| Secondary | Annualized Severe Safety of Estrogens in Systemic Lupus Erythematosus National Assessment - Systemic Lupus Erythematosus Disease Activity Index Flare Index (SFI) Flare Rate | Up to Week 260 | A severe flare is defined as any of the following: * Change in SLEDAI instrument score to \>12 * New or worse: central nervous system SLE; vasculitis; nephritis; myositis; platelets \<60,000/mL, or hemolytic anemia with hemoglobin \<7 grams per deciliter (g/dL) or decrease in hemoglobin \>3 g/dL and requiring: doubling prednisone dose, increase to \>0.5 milligrams per kilograms per day (mg/kg/day) or hospitalization * Increase in prednisone dose to \>0.5 mg/kg/day * New requirement for cyclophosphamide, azathioprine, methotrexate, or mycophenolate for SLE activity * Hospitalization for SLE activity * Increase in PGA score to \>2.5 |
| Secondary | Percentage of Time Spent in Lupus Low Disease Activity State (LLDAS) | Up to Week 284 | LLDAS is a composite endpoint defined as the following: i. SLEDAI-2K score ≤ 4, with no activity in a major organ system (renal, central nervous system, cardiopulmonary, vasculitis, fever); and ii. No new features of lupus disease activity compared with the previous assessment; and iii. SELENA-SLEDAI PGA ≤ 1; and iv. Current prednisone (or equivalent) dose ≤ 7.5 mg/day; and v. Standard maintenance doses of immunosuppressive drugs and approved biological agents. "No new features" is defined as any new SLEDAI-2K component that was not present at the previous assessment. The SELENA-SLEDAI PGA Scale ranges from 0-3, where 0 is no disease activity and 3 is maximum disease activity. "Standard maintenance doses" include drugs limited to those allowed per protocol. |
| Secondary | Percentage of Participants With Sustained LLDAS | Up to Week 284 | LLDAS is a composite endpoint defined as the following: i. SLEDAI-2K score ≤ 4, with no activity in a major organ system (renal, central nervous system, cardiopulmonary, vasculitis, fever); and ii. No new features of lupus disease activity compared with the previous assessment; and iii. SELENA-SLEDAI PGA ≤ 1; and iv. Current prednisone (or equivalent) dose ≤ 7.5 mg/day; and v. Standard maintenance doses of immunosuppressive drugs and approved biological agents. "No new features" is defined as any new SLEDAI-2K component that was not present at the previous assessment. The SELENA-SLEDAI PGA Scale ranges from 0-3, where 0 is no disease activity and 3 is maximum disease activity. "Standard maintenance doses" include drugs limited to those allowed per protocol. |
| Secondary | Duration of Sustained LLDAS as Defined by the Number of Visits in LLDAS | Up to Week 284 | LLDAS is a composite endpoint defined as the following: i. SLEDAI-2K score ≤ 4, with no activity in a major organ system (renal, central nervous system, cardiopulmonary, vasculitis, fever); and ii. No new features of lupus disease activity compared with the previous assessment; and iii. SELENA-SLEDAI PGA ≤ 1; and iv. Current prednisone (or equivalent) dose ≤ 7.5 mg/day; and v. Standard maintenance doses of immunosuppressive drugs and approved biological agents. "No new features" is defined as any new SLEDAI-2K component that was not present at the previous assessment. The SELENA-SLEDAI PGA Scale ranges from 0-3, where 0 is no disease activity and 3 is maximum disease activity. "Standard maintenance doses" include drugs limited to those allowed per protocol. |
