|Sjogren's Syndrome||Drug: RSLV-132 Drug: Placebo||Phase 2|
This is a multi-center, double-blind, placebo-controlled study to evaluate the impact of 8 intravenous infusions of RSLV-132 in 28 patients with primary Sjogren's syndrome. Each of the subjects will be randomized 3:1 (active:placebo) and will receive 8 infusions of 10 mg/kg of RSLV-132 or placebo as follows on days:
• 1, 8, 15, 29, 43, 57, 71, and 85
Potential subjects will be screened to assess their eligibility to enter the study within 60 days prior to study entry (i.e., prior to Baseline visit). Following Baseline evaluations on Day 1, subjects will receive their first infusion of RSLV-132 or placebo. Subjects will return to the research unit for follow-up visits as described in Appendix A.
Dose selection rationale: The dose level was chosen based on safety and tolerability data from Protocol 132-02 (multiple ascending dose study in SLE patients). Additionally, in a 6-month toxicology study in cynomolgus monkeys, 50 mg/kg of RSLV-132 was administered by IV infusion weekly. No dose-limiting toxicity was noted, therefore the No Observed Adverse Effect Level is at least 50 mg/kg, providing at least a 5-fold safety margin for this study.
RSLV-132 shall be prepared for each subject from individual stock vials provided by Sponsor. Details of dilution, dose preparation, and administration instructions will be provided in the Study Drug Reference Guide. The dose for each individual shall be based on the subject's body weight.

- Blood Cell Gene Expression [ Time Frame: Day 1 and Day 99 ]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.
- EULAR ESSDAI Total Score. [ Time Frame: Days 1, 29, 57, 85 and 99 ]Clinical disease activity: Change from Baseline to Day 99 in European League Against Rheumatism Sjögren's Syndrome Disease Activity Index Total Scores (imputed values with last observation carried forward). The scale ranges from 0 to 123. A higher score means more disease activity (worse outcome).
