    OBSErve US study design12,13

    An observational cohort study assessed the effectiveness of BENLYSTA 10 mg/kg + ST in adult patients with SLE over a 24-month period in US clinical practices across 27 states and included 92 rheumatologists (N=501). To qualify for enrollment, patients were required to have at least 8 infusions of BENLYSTA. The baseline was the date of first infusion. Physician-assessed clinical response was reviewed at 6-month intervals using medical charts and data collected using case report forms.

     

    Primary objective: Physician-assessed clinical response to BENLYSTA at 6 months. Between baseline and Month 6, ≥50% improvement in overall clinical response was reported for 48.7% of participants.

     

    Selected other objective: Changes in steroid use at 6-month intervals over a 24-month period.

     

    Study discontinuation: During the 2-year observation, 45% (n=224) were lost to follow-up or discontinued use of BENLYSTA. Common reasons for discontinuing BENLYSTA (n=122; 22.5%) include: patient request (40.2%), medication not effective (29.5%), and adverse event (12.5%).

     

    Key data limitations:

    • Lack of control group
    • Risk of selection bias
    • Validated disease assessment tool not consistently used
    • Patient attrition
    • Potential measurement error based on non-uniform categorization or interpretation of disease severity and treatment response
    • Reasons for change in steroid dose were not captured and may be unrelated to disease improvement/worsening

    Post hoc analysis in African-American and Hispanic patients

    The primary outcome measure was overall clinical response to BENLYSTA at the end of a 24-month period, based on physician’s assessment over the last 6-month period.

     

    Other clinical outcomes (assessed versus index at Month 6, 12, 18, and 24 post-index) included:

    • Physician-assessed SLE disease severity
    • Oral corticosteroid use
    • Utilization of assessment tools
    • Reasons for, and rate of, belimumab discontinuation

     

    Study discontinuation:

    • In the OBSErve US study, 501 patients with SLE were enrolled; 123 (24.6%) were African American and 88 (17.6%) were Hispanic, of whom 69 (56.1%) and 43 (48.9%), respectively, continued to receive BENLYSTA at Month 24
    • Of those patients who did not continue belimumab use over the 24 months, 26 (21.1%) African-American and 23 (26.1%) Hispanic patients were lost to follow-up, and 28 (22.8%) and 22 (25.0%), respectively, discontinued belimumab
    • The most common reasons for discontinuation in the African-American group were patient request (n=13) and medication inefficacy (n=7), and 2 patients discontinued belimumab due to an adverse event, while in the Hispanic group, the most common reasons for discontinuation were loss to follow-up (n=8) and loss of insurance or reimbursement (n=7)

     

    Care should be taken when interpreting the present findings due to the following limitations:

    • Patient attrition
    • Small sample size
    • Lack of a control group
    • Varied experience of participating clinicians with the clinical SLE tools
    • Analysis-by-responder bias
    • Use of subjective, non-validated assessments
    • Assessment tools not consistently used in approximately half of cases

    Early use in lupus study design14

    Immunosuppressant use analysis

    Real-world evidence: immunosuppressant use analysis over a baseline period of 24 months and an observation period of up to 5 years post index
    • Retrospective, real-world, longitudinal cohort study based on administrative claims
    • Data from the Komodo Health Database of de-identified claims between January 2015 and December 2022 were used
    • A total of 6841 eligible adults with a diagnosis of lupus were identified at index on January 1, 2017
    • Patient follow-up was over a maximum of 60 months post-index
    • Patients were stratified into 2 cohorts: those initiating BENLYSTA with no immunosuppressant or after immunosuppressant use. Patients were then further stratified by their baseline SLE disease severity, defined using a previously published algorithm based on measures of SLE disease activity and expert clinical opinion. This analysis excluded patients with mild disease activity and those with history of use of >2 immunosuppressants during the baseline period
    • Immunosuppressants of interest were: azathioprine, cyclophosphamide, cyclosporine, leflunomide, methotrexate, mycophenolate mofetil/mycophenolic acid, tacrolimus, and voclosporin
    • Results were reported descriptively and the time to OCS discontinuation was assessed using Kaplan-Meier

    Endpoints

    • Rate and severity of SLE flares
    • Time to organ damage occurrence
    • OCS use
    • All-cause HCRU

    Inclusion criteria

    • A lupus diagnosis before or on the index date based on:
      • ≥2 outpatient medical claims, OR
      • ≥1 inpatient/emergency department claim
    • Filled ≥1 prescription for BENLYSTA from January 2017 to May 2022
    • ≥18 years of age on the index date
    • ≥24 months of continuous enrollment before index date

    Exclusion criteria

    • Diagnosis of drug-induced lupus before the index date based on ≥1 outpatient, inpatient, or emergency department claim
    • Prescription of BENLYSTA or a Janus kinase inhibitor (ie, baricitinib, tofacitinib, upadacitinib, ruxolitinib, and fedratinib) during the baseline period (other biologic treatments were permitted)
    • Patients who had received ≥2 prior immunosuppressants during the baseline period

    Key data limitations

    • All results presented here are based on descriptive analyses and numerical differences are presented without statistical hypothesis testing
    • The 24-month baseline period may have resulted in small sample sizes
    • Medication usage:
      • The presence of a dispensed medication does not guarantee that the medication was taken as prescribed
      • Adherence to medication(s) was not measured
    • Difference between baseline clinical characteristics between cohorts
    • Reasons for change in steroid dose were not captured and may be unrelated to disease improvement/worsening
    • HCRU = healthcare resource utilization; OCS = oral corticosteroid.

    Organ damage PSM study design15

    A post hoc, PSM comparative analysis was performed to assess the difference in organ damage (SDI) progression between patients in BLISS-76 LTE* and from the TLC.

    PSM comparative analysis performed to assess the difference in organ damage (SDI) progression between patients in BLISS-76 LTE and from the TLC

    Endpoints15

    The primary objective was to compare organ damage progression (mean change in SDI score) from baseline to Year 5 in patients treated with BENLYSTA + ST or ST alone using propensity score matched data from the BLISS-76 LTE trial and the TLC. Secondary objectives included comparing the time to organ damage progression and the magnitude of damage accrual.

     

    Key limitations of this PSM study15

    • Post hoc analysis
    • Patients matched based on known variables only
    • Patients could not be matched by year of entry into the study
    • Differences in patient populations

     

    Patient characteristics

    Patients are matched based on propensity scores calculated using 17 predictors of organ damage, including:

    • Demographics (age, age squared, gender, race/ethnicity – Black or Asian/other, current smoker)
    • Clinical characteristics (history of: hypertension, dyslipidemia, proteinuria)
    • SLE-specific characteristics (SLE duration, number of ACR criteria at diagnosis, baseline SLEDAI score, baseline SDI – >1 or ≥2)
    • Medications (steroids, immunosuppressant(s), antimalarials)

    * To be eligible, patients on BENLYSTA had to be in the United States; regimen was BENLYSTA IV 10 mg/kg + ST.

    Chosen based on its size, the extent of organ damage in patients, and the severity of disease activity. Regimen was ST alone.

    IV = intravenous; PSM = propensity score matching; TLC = Toronto Lupus Cohort.

    Long-term extension study design16

    This was a post hoc analysis of pooled data from 3 open-label LTE studies (LBSL02 Phase 2 LTE, BLISS-76 LTE, and BLISS-52 + BLISS-76 LTE, excluding US patients from BLISS-76).

     

    Patients received BENLYSTA IV 10 mg/kg + ST every 28 days and must have completed treatment through Week 72 of LBSL02 and BLISS-76, or Week 48 of BLISS-52.

     

    Endpoints

    The SDI score was assessed among eligible patients in the BLISS-76 and BLISS-52 + BLISS-76 LTE studies, within the high disease activity population (anti-dsDNA positive and low C3/C4), and the 5-year completer population (patients with ≥5 years of follow-up after their first dose of BENLYSTA).

     

    Patients in the originator studies who received BENLYSTA 1 mg/kg were transitioned to BENLYSTA 10 mg/kg upon entering the LTE. BENLYSTA 1 mg/kg is not an approved dose and not included in the data shown.

    Key data limitations

    • As the studies were open-label and did not have a control arm, causal inferences about the effect of BENLYSTA cannot be made
    • There was an increased number of withdrawals in later years, resulting in a small study population as compared to baseline
    • The Phase 2 study included some patients who were autoantibody negative at baseline. In the Phase 3 trials, all patients were autoantibody-positive
    • The baseline SDI scores varied among patients and are not reflected in this figure

    anti-dsDNA = anti-double–stranded DNA.

    Safety profile

    Well-established safety profile based on the largest clinical trial program in lupus and lupus nephritis.

    Indication & Safety Info

    Indication

    Important Safety Information

    Indication

    BENLYSTA is indicated for patients aged ≥5 with active systemic lupus erythematosus (SLE) or active lupus nephritis who are receiving standard therapy. BENLYSTA is not recommended in patients with severe active central nervous system lupus.

    Important Safety Information

    CONTRAINDICATION

    Previous anaphylaxis with BENLYSTA.

    WARNINGS AND PRECAUTIONS

    Serious Infections: Serious and sometimes fatal infections have been reported and occurred more frequently with BENLYSTA. Use caution in patients with severe or chronic infections, and consider interrupting therapy in patients with a new infection.

     

    Progressive Multifocal Leukoencephalopathy (PML): Cases of JC virus-associated PML resulting in neurological deficits, including fatal cases, have been reported. If PML is suspected, immunosuppressant therapy, including BENLYSTA, must be suspended until PML is excluded. If confirmed, stop immunosuppressant therapy, including BENLYSTA.

     

    Hypersensitivity Reactions (Including Anaphylaxis): Acute hypersensitivity reactions, including anaphylaxis and death, and infusion-related reactions have been reported. Generally, reactions occurred within hours of the infusion but may occur later, including in patients who have previously tolerated BENLYSTA. Non-acute hypersensitivity reactions (eg, rash, nausea, fatigue, myalgia, headache, and facial edema) typically occurred up to a week after infusion. Monitor patients during and after treatment and be prepared to manage anaphylaxis and infusion-related reactions. Be aware of the risk of hypersensitivity reactions, which may present as infusion-related reactions. Discontinue immediately in the event of a serious reaction. With intravenous administration, if an infusion reaction develops, slow or interrupt the infusion.

     

    Depression and Suicidality: Depression and suicidality were reported in patients receiving BENLYSTA. Before adding BENLYSTA, assess patients’ risk of depression and suicide and monitor them during treatment. Instruct patients/caregivers to contact their HCP if they experience new/worsening depression, suicidal thoughts/behavior, or other mood changes.

     

    Malignancy: There is an increased risk of malignancies with the use of immunosuppressants. The impact of BENLYSTA on the development of malignancies is unknown.

     

    Immunization: Live vaccines should not be given for 30 days before or concurrently with BENLYSTA as clinical safety has not been established.

     

    Use With Biologic Therapies: Available data do not support the safety and efficacy of concomitant use of BENLYSTA with rituximab in patients with SLE. An increased incidence of serious infections and post-injection systemic reactions in patients receiving BENLYSTA concomitantly with rituximab compared to patients receiving BENLYSTA alone has been observed. The safety and efficacy of BENLYSTA concomitantly with other biologic therapies, including B-cell-targeted therapies, have not been established. Caution should be exercised if BENLYSTA is administered in combination with other biologic therapies.

     

    ADVERSE REACTIONS

    The most common serious adverse reactions in adult SLE clinical trials were serious infections; some were fatal. The most common adverse reactions (≥5%) were nausea, diarrhea, pyrexia, nasopharyngitis, bronchitis, insomnia, pain in extremity, depression, migraine, pharyngitis, and injection site reactions (subcutaneous injection).

     

    Adverse reactions reported in clinical trials with SLE pediatric patients (≥5 years) and adult patients with lupus nephritis were consistent with those observed in adult SLE trials.

     

    USE IN SPECIFIC POPULATIONS

    Pregnancy: There are insufficient data in pregnant women to establish whether there is drug-associated risk for major birth defects or miscarriage. After a risk/benefit assessment, if prevention is warranted, women of childbearing potential should use contraception during treatment and for ≥4 months after the final treatment.

     

    Pregnancy Registry: HCPs are encouraged to refer patients and pregnant women are encouraged to enroll themselves by calling 1-877-311-8972 or visiting https://mothertobaby.org/ongoing-study/benlysta-belimumab/.
