Descrizione

Inclusion Criteria:

  • Male or female participants ≥ 18 years of age or as per country-specific legal adult age, whichever is higher
  • Classification of Sjögren's disease according to ACR/EULAR 2016 criteria.
  • Seropositive for anti-Ro/SSA antibodies at screening
  • SSSD oral dryness score ≥ 5 and overall SSSD summary score ≥5 collected over 14 consecutive days during the Screening 2 period
  • Screening ESSDAI biologic and/or hematologic domain > 0 Note: laboratory abnormalities for scoring must be confirmed as associated with Sjögren's disease and not be due to other underlying conditions.
  • Stimulated whole salivary flow (sSF) rate > 0.3 mL/min at screening
  • Participants taking hydroxychloroquine (≤ 400 mg/day) are allowed to continue their medication, and must have been on a stable dose for at least 4 weeks prior to screening, which should be maintained throughout the 52 weeks of the blinded treatment period.
  • Predniso(lo)ne ≤ 5 mg/day or equivalent are allowed for up to 16 weeks post-randomization.

Exclusion Criteria:

  • Presence of another autoimmune rheumatic disease that is active and constitutes the principal illness, specifically:
  • Systemic sclerosis (SSc)
  • Any other associated connective tissue disease (e.g., lupus nephritis (LN), large vessel vasculitis (LVV), Sharp syndrome (mixed connective tissue disease)) that is active and requires immunosuppressive treatment outside the scope of this trial and would impede on Sjögren's disease organ domain assessments.
  • Concurrent diagnosis or history of fibromyalgia or overlapping inflammatory diseases
  • Prior treatment with B-cell-depleting therapy (e.g., rituximab, other anti-CD20 mAb, anti-CD22 mAb, or anti-CD52 mAb) within:
  • 36 weeks prior to randomization, or
  • As long as B-cell count is less than the lower limit of normal (LLN) or baseline value prior to receipt of previous B-cell-depleting therapy (whichever is lower) at Screening.
  • Prior treatment with ianalumab
  • Prior treatment with any of the following within the given period prior to Screening:
  • Within 5 half-lives prior to Screening: iscalimab (anti-CD 40 mAb), belimumab (anti-BAFF mAb), abatacept (CTLA4-Fc Ig), anti-tumor necrosis factor alpha (TNFα) biologic agents, immunoglobulins (i.v./s.c.), plasmapheresis, any other investigational biologic medicines under investigation for Sjögren's disease
  • Within 4 weeks OR drug-specific 5 half-lives elimination period (if longer than 4 weeks) prior to screening: i.v. or oral cyclophosphamide, mycophenolate mofetil (MMF), methotrexate, azathioprine, i.v. or oral cyclosporine A or any other immunosuppressants (e.g., JAK inhibitors or other kinase inhibitors).
  • History of hypersensitivity to any of the study drugs or their excipients, or to drugs of similar chemical classes (e.g., mAb of IgG1 class) or to any of the constituents of the study drug formulation (sucrose, L-histidine hydrochloride/L-histidine, polysorbate 20).

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change from baseline in SSSD oral dryness score
Lasso di tempo: Baseline to Week 52
The Sjögren's Syndrome Symptom Diary (SSSD) oral dryness score is a patient-reported measure assessing severity of mouth dryness. The mouth dryness symptom is scored daily on a numerical scale (higher scores = worse symptoms).
Baseline to Week 52

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change from baseline in SSSD summary score
Lasso di tempo: Baseline to Week 52
The SSSD summary score is calculated over a defined time window. Each symptom is scored daily on a numerical scale (higher scores = worse symptoms).
Baseline to Week 52
Change from baseline in ESSPRI score
Lasso di tempo: Baseline to Week 52
The EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) score is a validated patient-reported outcome assessing three symptom domains: dryness, pain and fatigue. Scores range from 0 (no symptoms) to 10 (worst imaginable symptoms).
Baseline to Week 52
Change from baseline in stimulated whole salivary flow (sSF)
Lasso di tempo: Baseline to Week 52
The stimulated whole salivary flow rate, is an objective functional assessment of salivary gland activity, measuring saliva production under stimulation. Higher values indicate better salivary gland function.
Baseline to Week 52
Change from baseline in Patient's Global Assessment (PaGA) NRS score
Lasso di tempo: Baseline to Week 52
The Patient's Global Assessment of disease activity captures the patient's overall perception of disease activity. It is assessed using a Numerical Rating Scale (NRS) from 0 to 10. Higher scores indicate worse perceived disease activity.
Baseline to Week 52
Proportion of participants achieving SSSD response
Lasso di tempo: Week 52
Proportion of participants achieving a clinically meaningful improvement in the SSSD summary score at Week 52.
Week 52
Proportion of participants achieving ESSPRI response
Lasso di tempo: Week 52
Proportion of participants achieving a clinically meaningful improvement in the ESSPRI score at Week 52.
Week 52
Change from baseline in SSSD eye dryness score
Lasso di tempo: Baseline to Week 52
The SSSD eye dryness item score is a patient-reported measure assessing severity of eye dryness. The eye dryness symptom is scored daily on a numerical scale (higher scores = worse symptoms).
Baseline to Week 52
Change from baseline in FACIT-Fatigue score
Lasso di tempo: Baseline to Week 52
The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) score is a 13-item questionnaire assessing fatigue and its impact on daily activities over the previous 7 days. Higher scores indicate less fatigue / better functioning.
Baseline to Week 52
Change from baseline in Sjögren's-Related Quality of Life (SRQoL) score
Lasso di tempo: Baseline to Week 52
The Sjögren's-Related Quality of Life (SRQoL) score is a disease-specific quality-of-life instrument evaluating the impact of Sjögren's disease on physical, emotional, social and daily functioning. Lower scores indicate better quality of life.
Baseline to Week 52
