Study Type Interventional
Study Design Allocation: Randomized;   Intervention Model: Parallel Assignment;   Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor);   Primary Purpose: Treatment
Condition Sjogren's Syndrome
Interventions Drug: RSLV-132
Drug: Placebo
Enrollment 28
Recruitment Details Participants were recruited between 12 December 2016 and 01 February 2018. Participants were recruited from the Investigator's medical clinics.
Pre-assignment Details Participants were randomized in a 3:1 ratio to either RSLV-132 or placebo. A total of 22 participants were randomised to RSLV-2 and 8 to placebo. Two participants randomized to RSLV-2 were withdrawn prior to the start of study treatment, one withdrew consent and one was found not to meet the eligibility criteria.

Measure Description: The ESSDAI is a systemic disease activity index used in clinical studies. It includes 12 domains (i.e, organ systems: cutaneous, respiratory, renal, articular, muscular, peripheral nervous system, central nervous system, hematological, glandular, constitutional, lymphadenopathic, biological) and each domain is divided into 3 or 4 levels of activity (0 - No, 1 - Low, 2 - Moderate, 3 - High). The score from each domain is added to make the total score. The scale total score ranges from 0 to 123. A lower score represents less disease activity.
1.Primary Outcome
Title Blood Cell Gene Expression
Hide Description Interferon gene expression (mean log2 fold change from baseline to Day 99). The of expression of three IFN-inducible genes (HERC5, EPSTI1, CMPK2) was measured by qPCR to assess the IFN signature status (the altered pattern of gene expression) of Sjögren's syndrome patients.
