Could a protein called VISTA be the key to understanding MS?
NCT ID NCT06957145
First seen Jun 26, 2026 · Last updated Aug 14, 2026 · Updated 2 times
Summary
This study compares levels of a protein called VISTA in immune cells from people with multiple sclerosis (MS) or clinically isolated syndrome (CIS) and healthy volunteers. Researchers will take blood samples at the first attack and again at 6 and 12 months to see if VISTA levels change over time. The goal is to learn whether VISTA could serve as a biomarker or lead to new treatments for MS.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could point toward VISTA as a biomarker for MS and help develop new treatments that target the immune system.
- What could go wrong
- This is an early observational study with only 60 participants, so results may not apply to all MS patients. It measures proteins, not direct treatment effects.

Inclusion Criteria: * Patients aged 18 years or older diagnosed with MS or CIS according to the 2017 McDonald criteria. * No diagnosis of any autoimmune disease or malignancy. * No new diagnosis of autoimmune disease or malignancy during the 1-year follow-up period. * No use of antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), or steroid treatments within one month prior to blood sampling. * No vaccination within one month prior to blood sampling. * Not in the menstrual cycle at the time of blood sampling. Exclusion Criteria: * Age below 18 years. * Presence of a previous or newly diagnosed autoimmune disease or malignancy at the time of blood sampling. * Use of antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), or steroid treatments within one month prior to blood sampling. * Vaccination within one month prior to blood sampling * Being in the menstrual cycle at the time of blood sampling * Patients without a definitive MS diagnosis according to the 2017 McDonald criteria will not be included in the study.
