Living with Multiple Sclerosis (MS) can be a challenging journey, and navigating the world of treatment options is often overwhelming. As someone with personal experience using Interferon beta-1b, I’ve also connected with friends who rely on therapies like Rebif, Ocrevus, and others. Driven by the desire to find the most effective treatment, I’ve delved into extensive research to explore the various therapies available. In this post, I’ll share insights into some of the leading treatments for MS, helping you understand the options that might work best for your situation.
Multiple sclerosis (MS) is a disease that affects the central nervous system, disrupting the flow of information within the brain and between the brain and body. While there is no cure for MS, various treatments can help manage symptoms and slow the disease’s progression. This article will explore some of the top treatments available for MS.
Key Takeaways
- Ocrelizumab (Ocrevus) is effective for both relapsing-remitting and primary-progressive MS.
- Interferon beta medications like Avonex and Rebif help reduce the frequency of relapses.
- Glatiramer acetate (Copaxone, Glatopa) works by blocking the immune system’s attack on myelin.
- Natalizumab (Tysabri) is an infusion therapy that can help manage severe cases of MS.
- Alemtuzumab (Lemtrada) targets immune cells and is used for patients who have not responded to other treatments.
Ocrelizumab (Ocrevus)
Ocrelizumab, marketed as Ocrevus, is a disease-modifying drug for multiple sclerosis (MS). It is approved for both relapsing-remitting MS (RRMS) and early primary progressive MS (PPMS). This medication is administered as an infusion into a vein by a healthcare professional.
How It Works
Ocrelizumab is a humanized monoclonal antibody that targets CD20-positive B cells, a type of immune cell that plays a significant role in the MS disease process. By targeting these cells, Ocrevus helps reduce the frequency of relapses and slows the progression of disability.
Effectiveness
Clinical trials, including the OPERA 1 and 2 studies, have shown that Ocrevus significantly lowers the annualized relapse rate compared to interferon beta-1a. In these trials, patients receiving Ocrevus had a 46-47% lower relapse rate. Additionally, the drug has been shown to reduce the number of new or enlarging T2 lesions and gadolinium-enhancing lesions on MRI scans.
Side Effects
Common side effects of Ocrevus include infusion reactions, such as irritation at the injection site, low blood pressure, fever, and nausea. There is also an increased risk of infections and, in rare cases, certain types of cancer, including breast cancer.
Ocrevus is the only disease-modifying therapy approved by the FDA to treat both relapsing-remitting and primary-progressive forms of MS.
Administration
Ocrevus is given via an intravenous infusion. The initial dose is administered in two separate infusions, two weeks apart. Subsequent doses are given every six months.
Important Considerations
Patients with a hepatitis B infection should not take Ocrevus. Regular monitoring is essential to manage potential side effects and ensure the treatment’s effectiveness.

Interferon beta (Avonex, Rebif, Betaseron)
Interferon beta is a common treatment for multiple sclerosis (MS). It includes 3 main types: Avonex, Rebif and Betaseron. Rebif does not cure MS but it helps reduce the symptoms of MS and decrease the number of relapses. All medications are designed to help manage relapsing forms of MS.
Avonex is usually given as a weekly intramuscular injection. Studies have shown that it can reduce the annual relapse rate by 29%. Over two years, disease progression occurred in 21.9% of patients using Avonex compared to 34.9% in those on a placebo.
Rebif, on the other hand, is administered three times a week via subcutaneous injection. Research indicates that higher doses of Rebif can reduce relapse rates by up to 33%. Patients on Rebif also showed a significant reduction in disability and MRI lesion burden.
Betaseron is also a subcutaneous injection but is usually administered every other day. It is used to reduce the frequency of relapses in relapsing-remitting MS (RRMS) and can also be used in certain forms of secondary-progressive MS (SPMS) that still have active relapses.
Key Points
- Avonex: Weekly intramuscular injection, 29% reduction in annual relapse rate.
- Rebif: Thrice-weekly subcutaneous injection, up to 33% reduction in relapse rate.
- Betaseron: A subcutaneous injection usually administered every other day. All medications help manage relapsing forms of MS.
When choosing between Avonex and Rebif, consider factors like injection frequency, potential side effects, and personal lifestyle. Rebif is often preferred for its higher efficacy in reducing relapses, but it may come with more injection site reactions.
Glatiramer acetate (Copaxone, Glatopa)
Glatiramer acetate is a synthetic polypeptide used to reduce the frequency of relapses in patients with relapsing-remitting multiple sclerosis (RRMS). It is available under the brand names Copaxone and Glatopa.
Dosage and Administration
- 20 mg/mL SC injection: Administered once daily.
- 40 mg/mL SC injection: Administered three times a week.
Efficacy
In clinical trials, glatiramer acetate has shown a significant reduction in relapse rates. For instance, a study with 1,404 patients demonstrated that the 40 mg dose reduced mean annualized relapse rates by 34% compared to placebo.
Side Effects
Common side effects include:
- Injection site reactions
- Flu-like symptoms
- Liver test abnormalities
Special Considerations
Glatiramer acetate is often recommended for patients with uncontrolled depression, as it may be a safer option compared to other treatments.
Glatiramer acetate injection is used in the treatment of relapsing forms of multiple sclerosis. There are currently three FDA-approved glatiramer acetate products available.
Conclusion
Glatiramer acetate offers a flexible dosing regimen and has been proven effective in reducing relapse rates in RRMS patients. It is a valuable option for those who prefer injectable treatments and may be particularly suitable for patients with certain mental health conditions.
Natalizumab (Tysabri)
Natalizumab, marketed as Tysabri, is a treatment for relapsing forms of multiple sclerosis (MS). Approved in 2004, it is administered through an intravenous infusion every four weeks. Tysabri works by preventing immune cells from entering the central nervous system (CNS), which helps reduce relapse rates and slow down disability progression.
However, Tysabri has been linked to a serious brain infection called progressive multifocal leukoencephalopathy (PML). The risk of PML increases if the patient has JC virus antibodies, has used immunosuppressive drugs before, or has been on Tysabri for more than two years. To manage this risk, patients are monitored under the TOUCH Prescribing Program.
In clinical trials, Tysabri reduced relapse rates by 68% and slowed disability progression by 42% over two years. Despite its risks, it remains a valuable option for those who have not responded to other treatments or have very active disease.
Alemtuzumab (Lemtrada)
Alemtuzumab, marketed as Lemtrada, was approved by the FDA in November 2014 for treating relapsing forms of multiple sclerosis (MS). This includes relapsing-remitting disease and active secondary progressive MS. Due to the risk of severe autoimmune side effects, it is reserved for patients who have not responded well to at least two other MS treatments.
Alemtuzumab is a monoclonal antibody that targets CD52, a protein on the surface of immune cells, leading to the destruction of these cells. This helps reduce the frequency of MS relapses but also increases the risk of infections and autoimmune disorders.
Treatment Regimen
- Initial treatment involves five consecutive days of intravenous infusions.
- A second course of three consecutive days is given one year later.
Safety and Monitoring
Alemtuzumab is only available through a restricted distribution program called Lemtrada REMS (Risk Evaluation and Mitigation Strategy). This program ensures that only certified prescribers can prescribe the drug and that patients are closely monitored for potential side effects.
Clinical Studies
Two major Phase III studies, CARE-MS I and CARE-MS II, compared alemtuzumab to high-dose subcutaneous interferon beta-1a (Rebif). In both studies, alemtuzumab significantly reduced annualized relapse rates. CARE-MS II, also significantly slowed the accumulation of disability.
Alemtuzumab is generally recommended for patients with aggressive MS or those who have failed other treatments.
Teriflunomide (Aubagio)
Teriflunomide, sold under the brand name Aubagio, is an oral medication approved by the FDA in September 2012 for treating relapsing forms of multiple sclerosis (MS). It is available in two doses: 7 mg and 14 mg. This medicine will not cure MS, but it may slow some disabling effects and decrease the number of relapses of the disease.
How It Works
Teriflunomide is a pyrimidine synthesis inhibitor. It works by reducing the activity of specific immune cells that are believed to be involved in the damage to nerves in MS.
Effectiveness
In clinical trials, such as the TEMSO study, teriflunomide significantly reduced the annual relapse rate by 31% compared to a placebo. It also showed a reduction in disability progression at the 14 mg dose.
Common Side Effects
- Headache
- Hair thinning
- Diarrhea
- Nausea
- Increased liver enzymes
- Flu-like symptoms
- Tingling or numbness
Safety Precautions
- Regular blood tests are needed to monitor liver function and blood cell counts.
- Blood pressure should be checked before starting treatment and periodically thereafter.
- Women of childbearing potential must use reliable contraception, as teriflunomide can cause birth defects.
Contraindications
- Severe liver impairment
- Pregnancy or women not using reliable contraception
- Current treatment with leflunomide
Important Notes
If a liver injury occurs, teriflunomide should be stopped immediately, and an accelerated elimination procedure should be started. This involves using activated charcoal or cholestyramine to remove the drug from the body faster.
Without this procedure, it can take up to 2 years for the drug to leave the body completely.
Dimethyl fumarate (Tecfidera)
Dimethyl fumarate, also known as Tecfidera, is an oral medication approved by the FDA in 2013 for treating relapsing forms of multiple sclerosis (MS). This medicine will not cure MS, but it may slow some disabling effects and decrease the number of relapses of the disease. The active ingredient in Tecfidera is dimethyl fumarate, which works by activating the Nrf2 pathway, a key player in protecting cells from damage.
Dosage and Administration
Tecfidera is taken orally in pill form, with the recommended dosage being 240 mg twice daily. Patients usually start with a lower dose to minimize side effects and gradually increase to the full dose.
Effectiveness
Clinical trials have shown that Tecfidera can significantly reduce the annual relapse rate and delay the progression of physical disability. In the DEFINE trial, it reduced the proportion of patients who relapsed by 49% and the annualized relapse rate by 53%. The CONFIRM study also showed a 44% reduction in the annualized relapse rate.
Side Effects
Common side effects include flushing and gastrointestinal issues like nausea, diarrhoea, and stomach pain. These side effects are more frequent at the beginning of treatment and usually decrease over time. There is also a potential risk for a rare brain infection known as progressive multifocal leukoencephalopathy (PML), but this is still being studied.
Important Considerations
Patients should have regular blood tests to monitor liver enzymes and blood cell counts while on Tecfidera. It’s also important to discuss any other medications being taken to avoid adverse interactions.
Tecfidera offers a convenient oral option for managing relapsing forms of MS, helping to reduce relapses and slow disability progression.
Fingolimod (Gilenya)
Fingolimod, marketed as Gilenya, is a once-daily oral medication used to treat relapsing forms of multiple sclerosis (MS). It was the first oral disease-modifying treatment for MS approved by the FDA. Fingolimod works by modulating sphingosine 1-phosphate receptors, which helps reduce the number of lymphocytes in the blood, potentially lowering their migration into the central nervous system.
Key Benefits
- Reduces the frequency of MS relapses
- Delays the accumulation of physical disability
- Approved for use in children and adolescents aged 10-17 with relapsing forms of MS
Side Effects
- Temporary slowing of the heart rate
- Edema (swelling) behind the eye
- Liver changes
- Risk of progressive multifocal leukoencephalopathy (PML), a rare brain infection
Special Considerations
- First dose should be administered in a medical setting due to potential heart rate decreases
- Requires monitoring for at least 6 hours after the first dose
- An ECG should be performed before and after the first dose
Fingolimod is a novel compound derived from a fungal precursor. Its unique mechanism of action sets it apart from other MS treatments.
Recent Developments
- In May 2018, Gilenya became the first disease-modifying therapy (DMT) approved for pediatric MS.
- In December 2019, the FDA approved generic versions of Gilenya for adults.
- In early 2023, Tascenso ODT®, an orally disintegrating version of fingolimod, was approved by the FDA.
Siponimod (Mayzent)
Siponimod, marketed as Mayzent, is an oral medication approved by the FDA in 2019. It is used to treat adults with relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting MS, and active secondary-progressive MS.
How It Works
Siponimod is a sphingosine-1-phosphate (S1P) receptor modulator. It works by affecting the immune system to reduce the frequency of relapses and slow the progression of the disease.
Dosage and Administration
The medication is taken once daily after a 5-day buildup to the proper dose. Patients need to follow the prescribed dosage schedule carefully.
Clinical Trials
The approval of Siponimod was based on the phase 3 EXPAND trial, which included 1,651 patients. The trial showed that Siponimod significantly delayed the risk of 3-month and 6-month confirmed disability progression compared to a placebo.
Side Effects
Common side effects include:
- Headaches
- High blood pressure
- Changes in liver function tests
- Diarrhea
- Dizziness
- Swelling in the extremities

Siponimod (Mayzent) was approved by the FDA in 2019. This tablet is taken orally and is approved for relapsing-remitting and secondary-progressive forms of MS.
Cladribine (Mavenclad)
Cladribine, marketed as Mavenclad, received FDA approval in 2019 for treating relapsing forms of multiple sclerosis (MS), including relapsing-remitting MS (RRMS) and active secondary-progressive MS (SPMS). This medication is often recommended for patients who haven’t responded well to other MS treatments.
Treatment Schedule
- Cladribine is taken orally in two annual courses, totalling up to 20 days over two years.
- No treatment is required in the third and fourth years.
Benefits
- Reduces disease activity, including disability progression and annualized relapse rate.
- Shows positive effects on MRI activity.
Potential Side Effects
- Lymphopenia (low white blood cell count)
- Herpes zoster infection
- Increased risk of malignancy (cancer)
- Fetal harm
- Common side effects: upper respiratory tract infections, headache, and decreased lymphocyte counts.
Cladribine is thought to be an immune reconstitution therapy, meaning that two short courses of oral treatment one year apart provide suppression of MS disease activity.
Important Considerations
- Not suitable for patients with active chronic infections or cancer.
- Not recommended for pregnant or breastfeeding women.
- Men and women should use contraception during treatment and for six months afterwards.
- Regular blood tests may be needed to monitor health while on cladribine.
Conclusion
In conclusion, while there is no cure for Multiple Sclerosis (MS), there are many treatments available that can help manage the disease and improve the quality of life for those affected.
