This study is testing a new treatment called IMS001 for people with Multiple Sclerosis (MS), a disease where the immune system attacks the brain and spinal cord. IMS001 comes from special cells called mesenchymal stem cells (MSCs), which might help change how the disease progresses. This is a Phase 1 study, meaning it’s the first step in checking if IMS001 is safe and how it affects the body.

To join, you must be between 18 and 65 years old, have MS, and not be doing well with your current treatments. You also need to be okay with getting MRIs, which are special pictures of your brain and spine.

• Study Length: This is a one-time dose study.
• Visits Needed: Participants must be available for the whole trial.
• Risks: You can't join if you have certain health issues, allergies, or are pregnant.

If you have certain allergies, other serious health issues, or are pregnant, you can't join. Also, if you’re participating in another study or can't commit to this one, you aren't eligible. This study is important to find out if IMS001 can help people with MS feel better.
