Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The change of SSRI-30 between the two groups at 24 weeks
Time Frame: 24 weeks
SS Responder Index (SSRI) is a composite endpoint, investigators defined an SSRI-30 response as a ≥30% improvement in at least two of five outcome measures (patient-assessed visual analogue scale scores for fatigue, oral dryness and ocular dryness, unstimulated whole salivary flow and ESR at 24 weeks
24 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in The European League Against Rheumatism (EULAR) Sjogren's Syndrome Patient Reported Index (ESSPRI) score from Baseline to Week 24
Time Frame: 24 weeks
The ESSPRI is composed of 3 scales - dryness, fatigue, and pain. Each scale is measured 0 - 10, 0 being no symptoms, 10 being maximal imaginable dryness, fatigue or pain. The total score is the mean score of the three scales. Baseline ESSPRI total score will be compared to week 24, end of treatment, ESSPRI total score.
24 weeks
Change in total score of the EULAR Sjogren's syndrome disease activity index (ESSDAI) from baseline to week 24
Time Frame: 24 weeks
The ESSDAI is a disease activity measurement that has 12 domains. The score of each domain is the product of the weight of the domain by the level of activity. Activity levels are 0 - 3, 0 being no activity, 3 being high activity. The total score is the sum of the score of all domains. Change in total score from BL to week 24 will be measured.
24 weeks
Change in Schimer's test
Time Frame: 24 weeks
The change from baseline in Schimer's test at 24 weeks. The Schirmer's test assesses tear secretion.
24 weeks
Change in Immunoglobulin G (IgG) concentration
Time Frame: 10 and 24 weeks
The change from baseline in IgG concentration at 10 and 24 weeks.
10 and 24 weeks
Change in serum complements C3 and C4 concentration
Time Frame: 10 and 24 weeks
The change from baseline in serum complements C3 and C4 concentrationat 10 and 24 weeks.
10 and 24 weeks
Change in titer of Rheumatoid Factors
Time Frame: 10 and 24 weeks
The change from baseline in titer of rheumatoid factors at 10 and 24 weeks.
10 and 24 weeks
