A Randomized, Double-blind, Placebo-controlled, Parallel-group Study of the Safety, Tolerability, Pharmacokinetics, and Therapeutic Efficacy of SAR441344 in Adult Patients With Primary Sjögren's Syndrome (pSjS)

Primary Objective:

To evaluate the therapeutic efficacy of one dose level of SAR441344 versus placebo over 12 weeks in adult patients with primary Sjögren's syndrome (pSjS), assessed by the change of the European League Against Rheumatism (EULAR) Sjögren's Syndrome Disease Activity Index (ESSDAI)

Secondary Objectives:

  • To evaluate the therapeutic efficacy of one dose level of SAR441344 versus placebo over 12 weeks in adult patients with pSjS
  • To evaluate the therapeutic efficacy on fatigue of one dose level of SAR441344 versus placebo over 12 weeks in adult patients with pSjS
  • To evaluate the pharmacokinetic (PK) exposure of one dose level of SAR441344 over 12 weeks in adult patients with pSjS
  • To evaluate the safety and tolerability of one dose level of SAR441344 versus placebo in adult patients with pSjS as determined by adverse events (AEs)
  • To evaluate the local tolerability of one dose level of SAR441344 versus placebo over 12 weeks in adult patients with pSjS
  • To evaluate the safety and tolerability of one dose level of SAR441344 versus placebo over 12 weeks in adult patients with pSjS determined by electrocardiogram, vital signs, and laboratory evaluations
  • To measure the immunogenicity of one dose level of SAR441344 versus placebo over 12 weeks in adult patients with pSjS

This is a multicenter, randomized, double blind, placebo controlled, parallel group proof of concept Phase 2 study to evaluate the therapeutic efficacy of SAR441344 in adult patients with primary Sjögren's syndrome (pSjS), as well as safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD).

  • Study visit frequency: every 2 weeks in the treatment period and every 4 weeks in the follow-up period.
  • The total duration of the study will be 24 weeks (28 weeks including maximum screening duration) for each participant, including a 12-week treatment period and a 12-week follow-up period.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline to Week 12 in ESSDAI Score
Time Frame: Baseline (Day 1) to Week 12
ESSDAI is validated and established outcome measurement for therapeutic efficacy in Sjögren's syndrome, evaluating disease activity mainly on extra-glandular manifestations. This score consists of 12 organ-specific domains (constitutional, lymphadenopathy, glandular, articular, cutaneous, pulmonary, renal, muscular, peripheral and central nervous system, hematological, biological), which are scored based on organ-specific items in 3 to 4 different severity grades (no, low, moderate, high; with 0=no and 3=high). These scores are summed up over all 12 domains in weighted way (severity grades are multiplied with weights ranging 1-6 depending on domain) to summarize into total score(0-123). Higher scores indicates worse outcome. Negative change from baseline indicates improvement. Baseline=Day 1 assessment value. Least squares (LS) mean is calculated using mixed models for repeated measures (MMRM). Observed values after occurrence of intercurrent events are excluded.
Baseline (Day 1) to Week 12

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline to Week 12 in European League Against Rheumatism (EULAR) Sjögren's Syndrome Patient Reported Index (ESSPRI) Score
Time Frame: Baseline (Day 1) to Week 12
The ESSPRI is a validated and established outcome measurement, reported by participants, which rates the key disease manifestations: fatigue, dryness, and pain, based on a numeric scale ranging from 0 to 10, where 0 is defined as no symptoms and 10 as maximum imaginable complaints. The total score is the mean score of the 3 scales and ranges from 0 to 10. Higher scores indicates worse outcome. A negative change from baseline indicates improvement. Baseline is defined as Day 1 assessment value. LS mean is calculated using MMRM. Observed values after occurrence of intercurrent events are excluded.
Baseline (Day 1) to Week 12
Change From Baseline to Week 12 in Multidimensional Fatigue Inventory (MFI) General Fatigue Subscale and Other Subscales Score
Time Frame: Baseline (Day 1) to Week 12
The MFI is a validated, 20 item self-report instrument to evaluate fatigue by investigating the following subscales: general fatigue, physical fatigue, mental fatigue, reduced motivation, and reduced activity. Each subscale consists of 4 items that are scored using a scale from 1 ("yes, this is true") to 5 ("no, this is not true") on which the participants indicate how the listed statements applied to their current fatigue situation. Item scores are summed to create individual subscale score ranging from 4 to 20. A higher score indicates a higher degree of fatigue. A negative change from baseline indicates improvement. Baseline is defined as Day 1 assessment value. LS mean is calculated using ANCOVA. Observed values after occurrence of intercurrent events are excluded.

Time Frame: From first dose of IMP (Day 1) up to end of follow-up period (Week 24)
An adverse event (AE) was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of IMP, whether or not considered related to the IMP. TEAEs: AEs that occurred, worsened, or became serious during the TEAE period (time from the first IMP administration up to Week 24). Serious adverse events (SAE): Any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent disability/incapacity, or was a congenital anomaly/birth defect. An AESI: an AE (serious or nonserious) of scientific and medical concern specific to the Sponsor's product or program, for which ongoing monitoring and immediate notification by the Investigator to the Sponsor was required.
From first dose of IMP (Day 1) up to end of follow-up period (Week 24)
Number of Participants With Treatment Discontinuation and Withdrawals Due to TEAEs
Time Frame: From first dose of IMP (Day 1) up to end of follow-up period (Week 24)

Number of Participants With Increase in Pain Intensity Compared to Pre-dose Pain Intensity at Injection Site by Verbal Descriptor Scale (VDS)
Time Frame: Pre-dose (within 24 hours prior IMP dosing), post-dose (up to 15 minutes after dosing) and 2 hours post-dose at Weeks 2, 4, 6, 8 and 10
For the measurement of local tolerability, participants had a self-evaluation using a VDS before IMP administration, after completion of the IMP administration, and 2 hours post-administration. The participants were asked to report sensations at the injection site and rated the pain severity as following grading: 0= no pain; 1= mild pain; 2= moderate pain, 3= severe pain, 4= very severe. A positive change in VDS score indicated a higher pain severity compared to the pre-dose pain. The numerical change provides the number of grades the pain got worse (positive change) or improved (negative change). Total number of participants with pain intensity increase (change in VDS score of greater than or equal to 1) compared to pre-dose pain intensity are reported.
