Trial Outcomes & Findings for A Study of RSLV-132 in Subjects With Primary Sjogren's Syndrome (NCT NCT03247686)

NCT ID: NCT03247686

Last Updated: 2021-04-02

Results Overview

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.

Participant Flow

Participants were recruited between 12 December 2016 and 01 February 2018. Participants were recruited from the Investigator's medical clinics.

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 Two participants randomized to RSLV-2 were withdrawn prior to the start of study treatment, one withdrew consent and one was found not to meet the eligibility criteria.
