Switching From Tysabri to Tecfidera

1/6/2014

Q. What is your experience in switching patients from Tysabri to Tecfidera? How efficient is this in preventing relapses?

A. We do not have much experience yet with switching patients from Tysabri to Tecfidera. I suspect we will have the same problems that we have experienced with switching patients from Tysabri to other drugs. I advise following these simple rules for now:

Do not switch unless you must. The "must" reason is usually a high index JC virus antibody result (high values are either > 1 or> 1.5 by most MS specialists) at any time. After at least a year of monthly Tysabri infusions, discuss with your doctor the possibility of increasing the interval between infusions to 8 weeks. This is done in many centers and theoretically should decrease the risk of PML. Of course, you will still need to be monitored with regular MRI scans even with the increased interval between infusions
If you do switch to another drug, make sure you start the drug at the same time as your last Tysabri infusion or even before the last infusion for some drugs. The timing will depend on the drug you choose but generally you want to avoid wash out periods where you are off medication
Generally do not switch to another drug or class of drugs that you did not respond to adequately prior to starting Tysabri
Ask you MS specialist about obtaining a repeat MRI scan of the head with and without gadolinium 4 to 6 months after the last infusion of Tysabri. This will help detect early recurrent activity that requires the addition of steroids or another treatment.

Good luck

It's outraging how when discussing starting Tysabri, most neurologists don't talk about not having (efficient) strategies to quit it, or they make it sounds soooo minimal. I think patients should be warned, especially when patients are women who are very likely to be attempting pregnancy in following years. I wish i was...

Maria- what is your point exactly. Your tone sounds dismissive. I do hope that was not your intent. I have a 2 year old and a 4 year old. I have had long periods of time when I couldn't even hold them. They've seen the ambulance come to get me when, out of nowhere, my legs wouldn't work. My aunt died from complications due to MS. Not unlike many auto immune diseases, it is a scary and debilitating, often painful, disease. And, like any scary health issue, it deserves hype.

maria why aren't you more considerate about such involuntary medical conditions that no one chose to acquire?

Maria from Romania,
MS is a disease that can cripple one horribly, prevent one from living a decent life, or kill, as it did my mother.
There are no completely effective treatments, and once a body or body part is crippled, that crippling can not be reversed.
I am from New York, and have an MBA from NYU.
I also have breast cancer, metastatic, stage 4. It is being controlled by Fulvestrant.
Cancer is a piece of cake compared to MS, WHICH IS MUCH WORSE.
I have had MS for over 40 years and have watched myself become slowly crippled. It affects bladder and bowels as well as arms and legs, hands and feet.......any body system.......

I think you are cold and unfeeling and/or know nothing about MS.
You have no empathy.

Maria your ignorance is not needed for those who only want/need positivety during rough times

Well you obviously don't know anything about the disease then if you don't know what the "hype" is about. I am sure you are making your school so proud.

To Maria from Romania,
I had to read your post twice just to make sure I was really reading what you said.HOLY SMOKES. You don't understand all the"hype" is about MS, "just another autoimmune disease.": And you are going to practice medicine? Stay away from me!

My. Daughter has had MS 20yrs diagnosed. at age 20.been blind, some days can't walk or even get out of bed in and out of hospital. I don't know what kind of degree you have, but you know nothing about MS, it takes away ones freedom and independence it's a very cruel disease, God help them find a cure.

Hello. What are some patients' experiences with switching from Tysabri to Tecfidera? I have been on and of Tysabri for close to 7 years and the recent literature suggests that those who are JCV+ must come off Tysabri for increased of PML. I'm very nervous about coming off Tysabri. It has been a miracle drug for me.

Tysabri has been a miracle drug for me too. My new doc just switched me to Tecfidera...no one would prewscribe me tysabri (since i moved arouned a lot and had many diff doctors)...so I had some symptoms (vision loss and foot drag) before starting the tecfidera. THe doc sai Tecfidera won't maqke me better, it'll just prevent me from getting worse...I don't like that.

I'm also switching from Tysabri to Tecfidera. I've been on Tysabri for almost 9 years. Prior to my first infusion in October of 2006..I could barely walk, or see. I have intense burning in the extremities, and the fatigue was devastating. By my 2nd infusion....I had no symptoms...and haven't had any since. However with a JCV index of 3.4...my risk of PML is higher than most. My Doc has recommended Tecfidera. I'm terrified. I'm terrified of a relapse and I'm terrified of the side effects. Any advice, stories, or support would be appreciated. Even if you haven't switched... I'd be interested in your experiences with Tecfidera.

Hi all, am taking Tysabri for the past 11+ yrs. very true ms cannot b cured, but is settled with less symptoms. During this time of Tysabri had 2 severe relapses which were controlled with cytoxin chemo with high dosages. Which helped me recover from being disabled. Yes I m JCV +. Not towards high side. So after goin through all phases I still would go for Tysabri. As its only drug I my case with no side effects. Rest gylenia etc did come up with continued symptoms. My neurologist in Florida has really helped me with positive thinking and got me out in dark times. Thank u Dr W. S. Any questions will b happy to answer regd treatment phases etc
