Advances in MS Treatment

  New treatments for MS are coming online all the time. Some are approved by the FDA, while others are still in clinical trials. See how they may help treat your symptoms.

 

Drugs May Help Rebuild Myelin

Two drugs, metformin (Fortamet, Glucophage, Glumetza, Riomet) and clemastine (Dayhist, Tavist), may help rebuild your myelin. Usually, metformin treats diabetes and clemastine helps with hay fever. Researchers found metformin can help myelin-making cells repair it better. Experts found clemastine helped with the speed of messages from your eye to your brain. Animal studies showed metformin can improve the effect of clemastine.

More research is needed about the effects on humans.

Pioglitazone May Prevent Myelin Damage

Experts are doing clinical trials with pioglitazone (Actos), a diabetes medication, in people with progressive MS. They want to see whether the drug can target immune system attacks on myelin. Pioglitazone may be a useful therapy to protect nerve fibers from more damage and even repair damage to myelin.

BTK Blockers May Lessen Nerve Damage

Bruton’s tyrosine kinase (BTK) plays a role in the survival of B cells, white blood cells that make antibodies. Some B cells are linked to MS relapses and progression because they attack myelin. BTK inhibitors (BTKis) target B cells that can do damage while leaving useful B cells alone. BTKis were first used to treat cancer. Now scientists are studying some BTKis – evobrutinib, fenebrutinib, orelabrutinib, and tolebrutinib – in clinical trials to find out how effective they are against MS.

ATA188 Targets EBV, May Help MS 

This therapy targets Epstein-Barr virus (EBV), which is believed to play a role in how likely you are to get MS. ATA188 involves T cells (white blood cells in the immune system) that target and kill cells infected with EBV. Experts are studying the proper dosages, safety, and success of this intravenous (IV) infusion and how it can help treat progressive MS. 

Stem Cell Therapy for Harmful Cells

This treatment uses or targets stem cells, which are cells that can turn into different types of specific cells all over your body. They can help your body repair itself. One form of stem cell therapy is hematopoietic stem cell transplantation (aHSCT). Experts use this to reset your immune system through chemotherapy. If you have MS, this will get rid of harmful cells that cause damage and swap them with healthy immune cells. 

DMTs That Can Change the Course of MS

Disease-modifying therapies (DMTs) can help control your MS symptoms. The FDA has approved different types of medication to treat and manage MS:

  • Ocrelizumab (Ocrevus), ofatumumab (Kesimpta), and ublituximab-xiiy (Briumvi) target CD20, a protein on the surface of B cells. These B cells are white blood cells that have been shown to play a role in MS.
  • Diroximel fumarate (Vumerity) lessens inflammation and stops nerve damage that may cause MS symptoms.
  • Fingolimod (Gilenya) reduces the MS relapse rate in adults and children. It’s the first FDA-approved MS drug for kids.

Other DMTs That Can Change the Course of MS

  • Ozanimod (Zeposia) can help with clinically isolated syndrome, relapsing-remitting MS, and active secondary progressive MS.
  • Ponesimod (Ponvory) can lower the chance of MS symptoms coming back by more than 30%.
  • Cladribine (Mavenclad) and siponimod (Mayzent) are other treatments that can lower your relapse rate if you have MS. They stop certain cells of the immune system from causing nerve damage.

Cladribine for Other Forms of MS

As mentioned, this drug already helps people with relapsing-remitting MS. The first trial of its kind is studying whether cladribine can help more advanced progressive MS. Experts are hopeful because it’s one of the few DMTs that can get inside your brain and spinal cord. That's why it’s so helpful for relapsing MS.

Cholesterol Drugs May Help With MS

Simvastatin (Flolipid, Zocor) is a statin doctors prescribe to treat high cholesterol. It may also help slow down secondary progressive MS. Some studies show that higher cholesterol levels are linked to worsened MS. Because of this, experts thought simvastatin might slow down MS progression if it lowers your cholesterol. But a more recent study found that the drug directly slows down the progression of MS, even if it doesn’t help your cholesterol levels.

Ibudilast Can Slow Brain Shrinkage

Ibudilast (MN-166) is an anti-inflammatory drug that lowers the action of an enzyme called phosphodiesterase. Blocking the enzyme can lessen inflammation and promote nerve growth. Ibudilast can’t stop new MS lesions. But it can slow brain shrinkage and stop some immune system actions that can lead to nerve damage. Researchers also found that ibudilast appears to help treat slowly evolving lesions (SELs) in people with progressive MS.

Stem Cell Therapy for Harmful Cells

This treatment uses or targets stem cells, which are cells that can turn into different types of specific cells all over your body. They can help your body repair itself. One form of stem cell therapy is hematopoietic stem cell transplantation (aHSCT). Experts use this to reset your immune system through chemotherapy.

What to Know About Lesions and MS

Multiple sclerosis (MS) is an autoimmune disease. For people with MS, the immune system mistakenly attacks the protective covering on nerve fibers. This covering is called myelin.1

The attacks by the immune system lead to the formation of lesions in the central nervous system (CNS). Lesions are areas of damage or inflammation.1

What are lesions?

The myelin sheath is a layer around the nerves. It allows for efficient transmission of signals between the brain, spinal cord, and the rest of the body. When the myelin is damaged, the nerve signals become disrupted and neurons can degenerate. This can lead to various MS symptoms.1,2

A lesion is a damaged or scarred area. In MS, they are caused by the inflammation from the immune system attacking the myelin. Lesions are sometimes called plaques. Not all lesions in the CNS are caused by MS. But lesions are an important sign of MS. Doctors use the presence and location of lesions to help diagnose and track MS.1,2

MS lesions can occur throughout the CNS, including the brain, spinal cord, and optic nerves (the nerves that transmit signals from the eyes). Lesions are caused by focal inflammation that results in damage to the myelin and nerves. This damage ultimately leads to scar tissue. Lesions can vary in size and location. Lesions can be detected with imaging techniques such as magnetic resonance imaging (MRI).

What do lesions look like on MRI scans?

Doctors use MRI scans to look for lesions. In MS they often use an MRI scan with contrast. This means they inject a contrast fluid that contains gadolinium. The gadolinium shows up white (“lights up”) on certain MRI sequences where inflammation is happening. So, doctors look for white patches on these MRI sequences to detect active lesions with inflammation. Lesions older than 3 months typically will not light up with gadolinium.

While gadolinium only highlights newer lesions with ongoing inflammation, other MRI sequences can reveal all lesions, new or old, without any gadolinium. Combining these different MRI techniques allows doctors to identify both newer active and older inactive lesions.

Over time, some lesions may show up as a black spot on some MRI sequences. This means the CNS tissue has suffered so much damage that it completely degenerates or disappears. Some lesions have been shown to grow slowly over time. These are called chronic active lesions or smoldering lesions. Research shows that smoldering lesions may be a risk factor for progressive MS.

How are lesions used to diagnose and monitor MS?

Lesions play an important role in the diagnosis and monitoring of MS. Diagnosing MS often involves imaging, like an MRI, to look for signs of damage in the CNS. But MS is not the only cause of lesions. Radiologists review every MRI and look for signs of diseases. An MRI report may include lists of all possible conditions that could explain the results.

An MRI with lesions does not mean you definitely have MS. For a final MS diagnosis, a doctor will typically use a physical exam and questions about your medical history. They may confirm the diagnosis or rule out other conditions with other tests like bloodwork or a spinal tap.

If you are already diagnosed with MS, your doctors may use MRI images to look for evidence of ongoing disease activity such as new lesions. Current MS disease modifying therapies help prevent development of new lesions. New lesions on an MRI might suggest your current therapy is not working for you. MRIs taken over time can also show changes in old lesions. Sometimes old lesions can shrink or fade overtime. If lesions are growing or spreading, it may mean you need to consider new treatments.

If you are getting multiple MRIs over time of the same area of your body, try to get the MRIs at the same facility. This helps with tracking because the MRI machine and technique will be more consistent.

You may have access to MRI results before meeting with your doctor. But it can be a good idea to wait to review results with a professional. Doctors are trained to interpret the results and can address any concerns you may have.

Can Vitamin D Help MS?

 By Stephanie Watson

You might have heard that vitamin D helps to lower the risk for multiple sclerosis (MS). Or that it helps lessen symptoms in people who already have the disease. Evidence suggests that getting enough of this vitamin might protect against MS by holding back your immune system from attacking your own nerve cells.

But the link between vitamin D and MS isn't proven yet.

The MS-Vitamin D Link

This fat-soluble vitamin acts like a hormone in your body. Vitamin D also helps your immune system work better and to tamp down inflammation.

Those protective actions are important in autoimmune diseases like MS where your body turns against itself. In MS, cells of your immune system attack the coating around nerve fibers, called myelin, and leads to such hallmark symptoms as numbness, weakness, and blurry vision.

Research finds that vitamin D might help repair myelin and guards your nerves from damage.

Can Vitamin D Prevent or Slow MS?

Researchers aren’t sure if vitamin D can keep you from getting MS in the first place. Your body makes most of the vitamin D it needs from sunlight on your skin. People in northern climates like Scotland and Scandinavia are more likely to have MS compared with those who live in much sunnier climates. Studies show that people who get more sunlight and more vitamin D in their diets have a lower risk for MS overall.

There's some evidence that vitamin D might slow MS and make the disease less severe. Studies have found a link between higher vitamin D levels in the blood and less active disease, fewer lesions in their brain and spinal cord, and fewer relapses of symptoms.

In other studies, people with MS who had higher vitamin D levels had less severe disease and disability.

Do I Need More Vitamin D?

It's common for people with MS to be low on this vitamin. It may be hard for you to get outside to get sun often enough. Low vitamin D can also be a side effect of corticosteroids and other MS medications.

Your doctor can run a blood test to check your vitamin D level. You might be able to make up the difference by eating more fatty fish, eggs, and other foods that are high in vitamin D. Or, your doctor might suggest you take a supplement.

It's not clear whether taking a daily vitamin D supplement protects people from getting MS, or slows the disease in those who already have it. Studies suggest it might help, but this hasn't been proven. But since supplements are usually safe to take, it may not hurt to try them.

What Dosage Is Best?

Experts can’t say how much vitamin D is needed to prevent or slow MS. Different medical groups disagree on the ideal amount.

Official recommendations for adults is 400 to 600 international units (IUs) of vitamin D daily.

Ask your doctor what’s right for you. Be careful not to overdo it. Vitamin D helps your body absorb calcium, and you might end up with too much of that mineral. High calcium levels can weaken bones, damage the heart, and increase the risk for kidney stones.

If you already have MS, your doctor can check whether your vitamin D levels are too low. If so, it might make sense for you to take a supplement.

Inside An MS Exacerbation


By Devin Garlit · 

Exacerbation, relapse, flare-up, attack: these are all names for the same thing with regard to Multiple Sclerosis. The general definition of this event is the occurrence of new or worsening of old symptoms lasting for more than 24 hours and taking place at least 30 days after a similar event. While this can be standard occurrence for those with Multiple Sclerosis, not everyone actually understands what’s going during this period. Understanding what is happening during an exacerbation is critical for those with MS. With that in mind, I’ll do my best to help break it down as simply as I can.
What’s happening to the body during an MS exacerbation?
During one of these moments, the disease has caused your own immune system to attack your body. Specifically, your immune system begins to assault your central nervous system. Its weapon of choice? Inflammation (caused by various immune cells). This inflammation damages myelin, a fatty substance that surrounds and helps insulate our nerves. This insulating layer makes sure our nerves properly conduct the electrical signals that our brain sends to the other parts of our body (think of it as the plastic covering on an electrical wire). When this layer is damaged, those signals don’t move fast enough or at all, which is where we start to see our symptoms. Can’t lift your leg fast enough or at all? The myelin around a nerve between your brain and leg has been compromised and the signal isn’t traveling as efficiently as it should be. Not only does our immune system damage the myelin, but it also damages the cells needed to regrow it.
When the immune system attacks
These moments that we call exacerbations (or whichever term you like) are when the immune system is making its attack. It’s when the immune system has created a lot of inflammation in your central nervous system, and it’s damaging that myelin layer. Not only does this inflammation damage that protective coating, but it also has an effect on those signals that are traveling through that part of the central nervous system. We use steroids to fight exacerbations as they help to reduce this inflammation.
When a relapse is over: the aftermath
When an exacerbation is over, these damaged areas of myelin develop some scar tissue (that’s where we get the term sclerosis in multiple sclerosis, we are left with multiple scars; these scars are also referred to as plaques or lesions). Once all that inflammation is gone or significantly reduced, some of that myelin can regrow, but it never grows back completely or strong enough due to the scarring and because the cells needed to facilitate regrowth have been damaged. This regrowth, coupled with the reduction in inflammation, is why people can seem to bounce back after an exacerbation. They may even seem like they are completely well again. That’s why people often use the term “relapse,” because they seem to improve or go back to the way they were. This is a pattern that is extremely common in people diagnosed with the Relapsing-Remitting form of the disease. However, the more exacerbations you have, the more your ability to bounce back becomes hindered.
Accumulating damage over time
The more scars you have and the more cells that help regrow myelin are damaged, the less you are able to recover. In the past, maybe a damaged nerve could still get the brain’s signal where it needed to go, even if not the most efficiently (unless an outside influence temporarily triggered an issue). As more damage occurs over time though, the ability of that nerve to do its job, no matter the situation, becomes compromised. Basically, that’s how people with MS can worsen over time. That’s why doctors try to not only shorten the length of exacerbations through steroids, but to minimize the overall number of them with disease-modifying drugs.

Multiple Sclerosis and CBD


Multiple Sclerosis (MS) is a disease that impacts the body’s central nervous system (CNS) including the brain, optic nerves, and spinal cord. MS consists of an abnormal response of the body’s immune system. From here, the immune system targets myelin (a substance that surrounds and insulates the body’s nerves), and myelin gets damaged, which then produces scars (sclerosis). These scars are believed to be the cause of the painful symptoms MS patients experience.

Although MS causes various painful symptoms, over 85 percent of MS patients experience spasticity. Fortunately, though, based on the studies have been conducted on cannabis and MS so far, most indicate that cannabinoids are associated with self-reported spasticity improvements. It has also been found that CBD contains anti-spasm properties. Additionally, the American Academy of Neurology has expressed that cannabis is effective for the treatment of pain and spasticity. Then, one Israel study discovered that cannabis can safely alleviate pain in older MS patients and those with other chronic conditions, such as Crohn’s Disease.

Currently, 20-60 percent of MS patients consume cannabis, and many use topical cannabis products as their primary delivery method. To help treat muscle spasms and pain, it’s common for MS patients to use cannabis topically, so they can apply the medicine onto specific areas of their body. To achieve localized and rapid relief though, it’s recommended to use topical products with one example being CanniMed’s products, from which numerous Canadian MS patients have benefited.
