Alzheimer Disease study: Siponimod
Official title Repurposing Siponimod for Alzheimer's Disease
ClinicalTrials.gov ID: NCT06639282
What this study is testing
What is Siponimod?
Siponimod is an investigational oral medication being studied for the treatment of Alzheimer’s disease. Siponimod is designed to prevent T lymphocytes from leaving lymphoid organs, thereby modulating the immune system.
Also referred to as Mayzent.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether Siponimod can reduce brain atrophy in people with mild Alzheimer’s disease. It also looks at safety and how the drug might affect brain chemistry and memory.
- Who it's for
- You may be able to join if you have mild Alzheimer’s disease and are willing to take a daily pill for a year.
- What's involved
- You would take a small pill that starts low and gradually increases over 12 months. You will have brain scans and memory tests at the start, 6 months, 12 months, and 18 months. Blood and spinal fluid samples will be taken to check for brain chemicals.
- Time commitment
- The study lasts 18 months, with visits for scans, tests, and blood draws every 6 months and a final check after 6 months of stopping the pill.
- Phase 2: a mid-size study of how well it works
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
