A Study of RSLV-132 in Females With Sjögren's Disease

July 15, 2025 updated by: Resolve Therapeutics

A Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Assess the Impact of Intravenous RSLV-132 in Participants With Sjögren's Disease With Moderate to Severe Symptom Burden

The goal of this clinical study is to learn if RSLV-132 improves the symptoms of SS in adults. It will also learn about the safety of RSLV-132. The main questions it aims to answer are:

  • Does RSLV-132 improve the cardinal symptoms of Sjogren's including fatigue, dryness and pain?
  • Does RSLV-132 improve the tiredness/fatigue caused by Sjogren's?
  • What are the blood levels of RSLV-132 over time?
  • What is the immune (antibody) response in the body to RSLV-132?
  • What is the safety profile of RSLV-132?

Researchers will compare RSLV-132 to a placebo (a look-alike substance that contains no drug) to see if RSLV-132 improves the symptoms of pSS.

Participants will:

Take RSLV-132 or a placebo 13 times over 22 weeks Visit the clinic once every week for the first 2 weeks, then every 2 weeks until the end of treatment and then for a final time 4 weeks later (Day 211) for check-ups, tests and to answer questionnaires about their symptoms Record their symptoms every day on an electronic device
