What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Proportion of Participants With a 1 Point or Greater Change on the Salivary Gland Ultrasound (SGUS) Score for Parotid and Submandibular Glands
Time Frame: Week 4 and Week 12
|
The SGUS is a combination of the scores of the 4 salivary glands (2 parotid and 2 submandibular) each gland is scored on a 5-point scale (0 to 4; 4 being more severe), with the maximum total score being 16.
|
Week 4 and Week 12
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Salivary CXCL13 Levels
Time Frame: Baseline, Week 4 and Week 12
|
To assess the impact of parsaclisib on salivary CXCL13.
|
Baseline, Week 4 and Week 12
|
Number of Participants With Treatment-emergent Adverse Events
Time Frame: Up to 21 weeks
|
Adverse events reported for the first time or worsening of a pre-existing event after first dose of study drug.
|
Up to 21 weeks
|
Change in Whole Salivary Flow
Time Frame: Baseline, Weeks 4, 8, and 12
|
Defined as change in stimulated and unstimulated whole salivary flow from baseline
|
Baseline, Weeks 4, 8, and 12
|
Change in EULAR Sjögren's Syndrome Disease Activity Index
Time Frame: Week 12
|
Defined as change in ESSDAI.
The ESSDAI is a physician-assessed disease activity index for primary Sjögren's syndrome developed by the EULAR consortium.
It consists of 44 items in 12 organ-specific 'domains' contributing to disease activity (constitutional, lymphadenopathy, articular, muscular, cutaneous, glandular, pulmonary, renal, peripheral nervous system, central nervous system, hematological, biological).
Each domain is assessed for activity level (i.e., no, low, moderate, high) and assigned a numerical score based on pre-determined weighting of each individual domain.
An overall score is then calculated as the sum of all individual weighted domain scores.
Overall score is calculated as sum of all individual weighted domain scores (ranges from 0 (best) to 123 (worst activity).
|
Week 12
|
Change in EULAR Sjögren's Syndrome Patient Reported Index
Time Frame: Weeks 4, 8, and 12
|
Defined as Change in ESSPRI.
EULAR Sjogren's Syndrome Patient-Reported Index (ESSPRI) Score is defined as the change in score between baseline (Week -1) and Week 12.
The ESSPRI is a patient-reported, subjective symptom index for primary Sjögren's syndrome developed by the EULAR consortium.
It consists of three questions covering the cardinal symptoms of Sjögren's syndrome: dryness, fatigue and pain (articular and/or muscular).
Each domain scored on scale of 0-10 (0 =no symptom at all and 10 = worst symptom imaginable), and an overall score is calculated as the mean of the three individual domains where all domains carry the same weight.
|
Weeks 4, 8, and 12
|
Change in Symptom Scores for Dryness
Time Frame: Weeks 4, 8, and 12.
|
Defined as change in symptom scores for dryness of eyes, mouth, and vagina.
The dryness questionnaire will ask participants to rate the dryness of eyes, mouth, or vagina (female participants only) with 24-hour recall using an 11-point numerical rating system ranging from 0 (no dryness) to 10
|
Weeks 4, 8, and 12.
|
Patient Global Impression of Change Questionnaire
Time Frame: Baseline, Weeks 4, 8, and 12
|
Defined as proportions of participants in each PGIC category.
The PGIC asks a single question regarding how the patient is feeling since beginning new therapy.
The questionnaire uses a 7-point scale (from 1 to 7), ranging from "very much improved, 1" to "very much worse, 7
|
Baseline, Weeks 4, 8, and 12
|
Change in PROMIS Fatigue Short Form
Time Frame: Weeks 4, 8, and 12
|
Defined as change in PROMIS Fatigue short form.
The PROMIS fatigue short form includes 7 items with a rating scale of 1 to 5, 1 being no fatigue and 5 being severe fatigue.
The recall period is 7 days.

The FSFI is a brief, self-report measure of female sexual function (female participants only).
The questionnaire contains 19 item sexual functioning questionnaire to rate sexual function between 2.0 and 36.0,
where 2.0 is low sexual function and 36.0 is high sexual function.
