What You Need to Know Before You Apply

What is the purpose of this trial?

This trial uses stem cells from a patient's own fat, injected into the spinal fluid, to treat early-stage Multiple System Atrophy (MSA). The goal is to slow down the disease by supporting and protecting nerve cells.

Will I have to stop taking my current medications?

You may need to stop taking certain medications that could affect clinical evaluations, like levodopa and other anti-Parkinsonian drugs, at least four half-lives before study visits. The protocol does not specify about other medications, so it's best to discuss your specific situation with the study team.

Is stem cell therapy safe for humans?

Research shows that autologous mesenchymal stem cell therapy is generally safe in humans, with no serious adverse effects reported in studies for conditions like multiple system atrophy and multiple sclerosis. ^{1 2 3 4 5}

How is the stem cell treatment for multiple system atrophy different from other treatments?

This treatment uses the patient's own mesenchymal stem cells (a type of cell that can develop into different types of cells) derived from fat tissue, which are injected directly into the brain to potentially protect and repair damaged nerve cells. Unlike traditional drug treatments, which have limited effectiveness for multiple system atrophy, this approach aims to slow disease progression by reducing inflammation and supporting nerve cell survival. ^{1 2 6 7 8}

What data supports the effectiveness of this treatment for multiple system atrophy?

Research shows that mesenchymal stem cell therapy can delay the progression of neurological symptoms in multiple system atrophy patients, with improvements in movement and brain function observed over a 12-month period. Additionally, studies in mice suggest that adipose-derived stem cells may help reduce brain damage and improve motor skills. ^{1 2 5 6 7}

They must have normal cognition, not be pregnant or breastfeeding, agree to birth control if applicable, and haven't taken investigational drugs recently. Excluded are those with MRI contraindications, unstable medical conditions, certain medication use, or severe heart, liver or kidney diseases.

Inclusion Criteria

I have been diagnosed with probable multiple system atrophy (MSA).

The doctor thinks you will live for at least 3 more years.

I can walk by myself for at least 50 yards and my UMSARS I score is between 5 and 17.

Acceptable methods of birth control in this study are: surgical sterilization, intrauterine devices, partner's vasectomy, a double-protection method (condom or diaphragm with spermicide), hormonal contraceptive drug (i.e., oral contraceptive, contraceptive patch, long-acting injectable contraceptive) with a required second mode of contraception

I do not have any major health issues that could interfere with the study.

Participants who have taken any investigational products within 90 days prior to baseline, or with expected effects lasting beyond 60 days prior to baseline

What Are the Treatments Tested in This Trial?

Interventions

• Autologous Mesenchymal Stem Cells
• Placebo

Trial Overview This trial tests whether injecting patients' own mesenchymal stem cells into their spinal fluid is safe and effective for treating MSA. It's a randomized study where some get the real treatment while others get a placebo without knowing which one they received.

How Is the Trial Designed?

Group I: Arm 2 Active Control 2 Interventions

25 million mesenchymal stem cells administered intrathecally every 6 months for 2 injections (placebo injections at 3 month and 9 month timepoints)

Group II: Arm 1 Active Control 1 Intervention

25 million mesenchymal stem cells administered intrathecally every 3 months for 4 injections

Group III: Arm 3 Placebo Group 1 Intervention

Placebo (lactated Ringer's) administered intrathecally every 3 months for 4 injections

Published Research Related to This Trial

In a study involving 33 patients with MSA-C, those treated with autologous mesenchymal stem cells (MSC) showed a smaller increase in neurological deficits over 360 days compared to the placebo group, indicating potential efficacy in slowing disease progression.

MSC treatment was generally safe, with no serious adverse effects directly linked to the therapy, although some patients experienced small ischemic lesions from the intra-arterial infusion.

In a 12-month study involving 11 patients treated with mesenchymal stem cells (MSCs) and 18 control patients with multiple system atrophy (MSA), MSC therapy led to significant improvements in neurological function as measured by the unified MSA rating scale (UMSARS).

The MSC-treated patients showed enhanced brain activity in areas related to motor function, with no serious adverse effects reported, indicating that MSC therapy is both safe and potentially effective in slowing MSA progression.

In a study using a transgenic mouse model of multiple system atrophy (MSA), transplantation of human adipose-derived stem cells (ADSCs) significantly improved motor performance, indicating potential therapeutic benefits for MSA.

The mechanism of action for ADSC therapy appears to involve enhancing dopamine pathways, promoting autophagy to clear harmful proteins, reducing inflammation, and improving cell survival and myelination in the affected brain regions.

Transplantation of human umbilical cord blood mononuclear cells (hUCB-MCs) via lateral atlanto-occipital space puncture (LASP) showed significant improvement in neurological function in seven patients with multiple system atrophy (MSA) over a follow-up period of 3 to 5 years, particularly noted at 3 to 6 months post-treatment.

The procedure was found to be safe, with no serious adverse events reported, indicating that hUCB-MC transplantation via LASP could be a viable long-term treatment option for MSA.

Mesenchymal stem cells (MSCs) showed a significant protective effect against dopaminergic neurodegeneration in a model of multiple system atrophy (MSA), improving behavioral disorders and preventing neurodegeneration after transplantation.

The mechanism of MSCs involves modulating the expression of specific proteins, such as reducing polyamine modulating factor-binding protein 1 (PMFBP1) and altering 3-hydroxymethyl-3-methylglutaryl-CoA lyase (HMGCL) levels, which are linked to neuronal protection against damage.

Autologous mesenchymal stem cell (aMSC) transplantation for multiple sclerosis (MS) patients is safe, with a transplant-related mortality rate of 0%, based on a meta-analysis of 9 studies involving 133 patients.

The treatment shows promising efficacy, with 72% of patients achieving no evidence of disease activity (NEDA) at 6 months and 62% at 1 year, particularly benefiting from intrathecal injections which were associated with lower rates of disease progression.

Intravenously applied mesenchymal stem cells (MSCs) in a mouse model of multiple system atrophy (MSA) showed significant neuroprotection in the substantia nigra and reduced neuroinflammation by downregulating various cytokines, indicating their potential as a therapeutic strategy.

Despite the neuroprotective effects observed, there were no improvements in behavioral outcomes, suggesting that while MSCs may help protect neurons, further research is needed to understand their overall efficacy in improving symptoms of MSA.
