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.
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. 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.
