About this study

This was a randomized, double-blind, placebo-controlled, multicenter, parallel-group trial that was divided into 4 study periods.

Period 1: A screening period of 4 weeks to assess patient eligibility. Patients could be re-screened only once, and no study-related re-screening procedure could be performed prior to written re-consent by the patient.

Period 2: A blinded treatment period of 24 weeks. At baseline, eligible patients were randomized to one of three ianalumab dose arms (VAY736 5 mg, 50 mg or 300 mg s.c.) or a placebo arm (placebo s.c.). Blinded study drug was administered every four weeks (q4w) for a 24-week period.

Except for Japan, randomization was stratified by baseline ESSDAI score (<10 or ≥10 based on weighted scores). Separate blocks of randomization numbers were generated for patients in Japan versus the other countries participating to ensure that Japanese patients were equally distributed across all treatment groups in the study.

The primary endpoint was assessed at the end of Period 2 (Week 24). Treatment assignment in Period 2 remained double-blinded until the end of Period 3.

Period 3: An extended blinded treatment period of 28 weeks. After Week 24 assessments, patients in the ianalumab 300 mg arm were re-randomized in a 1:1 ratio to either continue on ianalumab 300 mg s.c. q4w or switch to matching placebo up to Week 52. Patients who received placebo during Period 2 were switched to ianalumab 150 mg s.c q4w up to Week 52. Patients who received 5 mg and 50 mg s.c. in Period 2 proceeded directly to safety follow-up (Period 4). Treatment assignment in Period 3 remained double-blinded.

Period 4: A post-treatment safety follow-up period. Patients who prematurely discontinued the study treatment at any time point or completed the treatment as planned entered the safety follow-up period. The minimum required duration of follow-up in the study was 20 weeks from the last administration of the study treatment (mandatory follow-up). The maximum duration of the follow-up was 2 years from the last dose of the study treatment, and it was defined by the level of recovery of CD19+ B-cells: conditional follow up (with reduced visit frequency) until CD19+ B-cell levels return to at least 80% of baseline or 50 cells/µL, whichever occurred first. Patients who had not yet recovered their B-cell counts two years after last ianalumab dosing were discharged from the study and had undergone their End of Study (EoS) visit. Patients who were treated with another immunomodulatory or immunosuppressive treatment (e.g., azathioprine, cyclophosphamide, high dose glucocorticosteroids) after completion of the minimum 20-week safety follow-up period were excluded from further safety follow-up.

Primary outcomes

  1. Least Squares Mean Change From Baseline in ESSDAI Score at Week 24

    Time frame: Baseline, Week 24

    The EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) instrument contains 12 organ-specific domains contributing to disease activity. For each domain, features of disease activity are scored in 3 or 4 levels according to their severity. These scores are then summed across the 12 domains in a weighted manner to provide the total score ranging 0-123. Higher scores on the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) scale are associated with poorer health states. A negative change from baseline indicates improvement in disease status.

Secondary outcomes

  1. Least Squares Mean Change From Baseline in ESSDAI Score at Weeks 4, 8, 12, and 16

    Time frame: Baseline, Week 4, Week 8, Week 12, Week 16

  2. Least Squares Mean Change From Baseline in ESSPRI Score at Week 24

    Time frame: Baseline, Week 24

    The EULAR Sjörgen's Syndrome Patient Reported Index (ESSPRI) is an established disease outcome measure for Sjögren's syndrome that is calculated by averaging the scales for pain, fatigue and dryness. The total score is the mean score of the 3 scales and ranges between 0 and 10 with higher values indicating more severity of symptoms. A negative change from baseline is a favorable outcome.

  3. Least Squares Mean Change From Baseline in ESSPRI Score at Weeks 4, 8, 12 and 16

    Time frame: Baseline, Week 4, Week 8, Week 12, Week 16

    The EULAR Sjörgen's Syndrome Patient Reported Index (ESSPRI) is an established disease outcome measure for Sjögren's syndrome that is calculated by averaging the scales for pain, fatigue and dryness.

  4. Least Squares Mean Change From Baseline in Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-F) Score Over 24 Weeks

    Time frame: Baseline, Week 24

    The Functional Assessment of Chronic Illness Therapy-Fatigue Scale (FACIT-F v4) is a short, 13-item, easy-to-administer tool that measures an individual's level of fatigue during their usual daily activities over the previous week. The level of fatigue is measured on a four-point Likert scale (4 = not at all fatigued to 0 = very much fatigued). The global score ranges between 0 and 52, with higher scores indicating less fatigue.

    Time frame: Baseline, Weeks 4, 8, 12 and 16

    Physician global assessment of overall disease activity (PhGA) was performed using a 100 mm visual analogue scale (VAS) ranging from no disease activity (score 0) to maximal disease activity (score 100), after the question "Considering all the ways the disease affects your patient, draw a line on the scale for how well his or her condition is today". A negative change from baseline is a favourable outcome.

  10. Patient's Global Assessment (PaGA) Score at Weeks 4, 8, 12, 16 and 24

    Time frame: Weeks 4, 8, 12, 16 and 24

    The PaGA of disease activity was performed using a 100 mm Visual Analog Scale (VAS) ranging from 0 (no disease activity) to 100 (maximal disease activity), in response to the question "Considering all the ways Sjögren's syndrome affects you, please draw a line on the scale to indicate how well you are doing today". A negative change from baseline is a favourable outcome.

  11. Least Squares Mean Change From Baseline in Salivary Flow Rate at Week 24

    Time frame: Baseline, 24 weeks

    Change from baseline in salivary flow rate (unstimulated and stimulated) at 24 weeks as compared to placebo.

    Unstimulated saliva is a mix of serous and mucous secretions coming primarily from the submandibular and minor salivary glands. The parotid gland produces the largest volume of stimulated saliva. Stimulated saliva accounts for 80-90% of daily salivary production.

  12. Percent Change From Baseline in Whole Blood CD19+ B-cell Counts.

    Time frame: Baseline, Week 24, Week 28

    B-cell counts were measured before, during and after treatment with VAY736. After stopping VAY736 treatment they were used to monitor patients for time to recovery of adequate CD19+ B cell counts prior to discharge from the study. Change from baseline in B-cell counts before, during and after treatment with VAY736 as well as the time to recover to baseline like values (defined as at least 80% of baseline counts or >= 50 cells/μL) were analyzed by descriptive statistics.

    Baseline was defined as the last assessment performed on or prior to the date of administration of the first dose of study treatment.

  13. Kaplan-Meier Analysis for Time to Recovery to Baseline Like Values for B-cell Counts

    Time frame: Up to two years from last dose patient received.

    B-cell counts were measured before, during and after treatment with VAY736. After stopping VAY736 treatment they were used to monitor patients for time to recovery of adequate CD19+ B cell counts prior to discharge from the study. Change from baseline in B-cell counts before, during and after treatment with VAY736 as well as the time to recover to baseline like values (defined as at least 80% of baseline counts or >= 50 cells/μL) were analyzed by descriptive statistics.

    Baseline was defined as the last assessment performed on or prior to the date of administration of the first dose of study treatment.

  14. Peak Serum Concentration of VAY736

    Time frame: baseline to week 24, then week 28

    Pharmacokinetic Concentrations
