MS drugs being trialled as coronavirus treatments
All the disease modifying therapies (DMTs) currently available for MS work by reducing immune attacks on the myelin coating that surrounds nerves. A number of them are being investigated to see if they can help people with COVID-19. But we won’t know if these drugs will work for coronavirus until they’ve been through rigorous clinical trials.
What DMTs are being investigated for COVID-19?
Several trials are looking at whether beta interferon, a drug commonly used for relapsing for MS, can be used to treat people with COVID-19.
Your body makes interferons, a type of protein, to dampen down inflammation. But the interferon drugs used for MS are man-made. They can reduce (and might prevent) the inflammation that damages nerves in MS. The beta interferon drugs licensed for relapsing MS include Avonex, Betaferon, Extavia, Plegridy and Rebif. They’re all injected under the skin.
Some of the beta interferons being tested for COVID-19 are injected and some are inhaled directly into the lungs as a mist.
Fingolimod is also being tested as a possible treatment for the severe breathing difficulties that affect some people with COVID-19.
In MS, immune cells attack the myelin covering around your nerves. Fingolimod reduces the myelin damage by stopping the immune cells reaching the nerves in the brain and spinal cord. Fingolimod is available for people with 'highly active' relapsing MS under the brand name Gilenya.
Ibudilast (also known as MN-166) is being developed for progressive MS by a company MediciNova. It is thought to work by protecting against cell death a A phase 3 trial is being planned for people with secondary progressive MS without relapses. There’s also a trial testing this drug for use in COVID-19 patients.
What does this mean for people with MS?
We don’t yet know whether people with MS who take beta interferon or fingolimod are less vulnerable to COVID-19. We’d need a large scale clinical trial to know for sure, but hopefully emerging data on MS and COVID-19 from around the world will start to give us some clues.
Medical regulations make sure there will be a sufficient supply before a drug can be made available. So there shouldn’t be shortages of these drugs for people with MS now or in the future.
If you’re currently taking beta interferon or fingolimod read our guidance on MS DMTs and coronavirus.
Take part in MS and coronavirus research
We need you to help us understand more about the impact of coronavirus on people with MS and find out if there are any links between MS DMTs and coronavirus.
We’re supporting the UK MS Register to run a survey looking at how COVID-19 is affecting people with MS.
We're here for you
If you want to talk about anything in this article, our MS Helpline is here with emotional support and information for everyone living with MS. The lines are open Monday to Friday, 9am to 7pm except bank holidays. Call freephone 0808 800 8000 or email email@example.com.
