Immune Profiling via Thoracic Duct Cannulation for Multiple Sclerosis
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores immune cells in people with multiple sclerosis (MS) by collecting lymph fluid through a safe, minimally invasive procedure called thoracic duct cannulation. The study compares immune responses in MS patients to those in healthy individuals, focusing on the impact of an approved MS treatment. Participants may be newly diagnosed or have used specific treatments previously. Ideal candidates have early MS, have been stable for the past month, and have not received recent immune-related treatments. As an unphased trial, this study allows participants to contribute to groundbreaking research that could enhance understanding of MS and improve future treatments.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it does mention that participants should not have used systemic glucocorticoids in the past 4 weeks and should have a treatment history limited to Interferons or glatiramer acetate, or be untreated. It's best to discuss your specific medications with the study team.
What prior data suggests that thoracic duct cannulation is safe for immune profiling in multiple sclerosis?
Research shows that thoracic duct cannulation is a minimally invasive procedure, meaning it doesn't involve major surgery and usually carries a lower risk of complications. Studies have found that interventional radiologists, who are doctors trained to use imaging to guide procedures, can perform it safely.
Limited data exists on serious side effects from thoracic duct cannulation itself. However, like any medical procedure, some risks may occur. These could include discomfort at the cannula (a thin tube) insertion site or minor issues like infection, but these are generally manageable.
In summary, while thoracic duct cannulation carries some risks, experienced professionals consider it safe. Always discuss any concerns with your healthcare provider before joining a trial.12345Why are researchers excited about this trial?
Researchers are excited about the thoracic duct cannulation technique for multiple sclerosis (MS) because it offers a new way to understand the immune system's role in the disease. Unlike standard MS treatments, which often focus on modifying immune responses with medications like interferons or glatiramer acetate, this method directly samples immune cells from the lymphatic system. By using either 'in-and-out' or 'indwelling' catheterization, doctors can get a clearer picture of immune cell activity before and after potential treatments. This could lead to more targeted and effective therapies in the future, as it provides insights that current blood tests can't fully capture.
What evidence suggests that thoracic duct cannulation is effective for immune profiling in multiple sclerosis?
Research suggests that thoracic duct cannulation might help manage the immune system in people with multiple sclerosis (MS) by correcting immune imbalances. This trial will compare two approaches: 'In-and-out' catheterization and 'Indwelling' catheterization. The procedure involves collecting lymph fluid to understand immune cell activity in the body. Studies have shown that the composition of lymph fluid varies significantly in different illnesses, providing clues about the immune response. Although direct evidence for its effectiveness in treating MS is still being gathered, the procedure is minimally invasive and has proven useful for diagnosing other conditions. This suggests it might aid in better understanding and possibly managing MS symptoms.12346

Are You a Good Fit for This Trial?
This trial is for adults aged 18-40, both healthy and those with Multiple Sclerosis (MS) who are neurologically stable. MS patients must have been diagnosed per the McDonald criteria, have an EDSS score of 0-4, and be untreated or only on specific MS medications. Participants must understand English and not have used steroids recently.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Thoracic Duct Cannulation
Trial Overview
The study involves collecting lymph fluid through thoracic duct cannulation to compare immune cells in MS patients versus healthy controls. It also examines changes in response to the FDA-approved therapy ofatumumab in MS patients.
How Is the Trial Designed?
2
Treatment groups
Experimental Treatment
Safety and immune-cell profile of lymphatic fluid in MS patients with a single time-point sampling of lymphatic fluids and peripheral blood compared to healthy controls. Two healthy controls and six patients with early MS (never treated or at least 90 days after discontinued treatment with glatiramer acetate or interferons), who consent to the 'In-and-out' catheter procedure. MS participants can also consent to OMB treatment with 2-year follow-up.

Twelve patients with early MS (never treated or at least 90 days after discontinued treatment with glatiramer acetate or interferons), who consent to treatment with OMB and to the indwelling catheter procedure with serial sampling and up to four healthy controls (no drug treatment)
