There is an alogirthm for the chances of contracting PML while on tysabri. I believe it is on the tysabri website among other places. I will see if I can find it for you and report back.

• Although the absolute risk for PML in patients treated with Tysabri cannot be precisely determined, the U.S. FDA and the company have released data suggesting that the risk increases with increasing time on therapy. • The company changed the label of Tysabri to indicate that the risk of PML is increased in patients who have been treated with an immunosuppressant (such as mitoxantrone, and less commonly, azathioprine and methotrexate) prior to receiving Tysabri.

Plasmorephis, blood filtering is already standard treatment to get Tysabri out of the body quickly if PML happens. I saw that a trial had been registered with the US FDA in clinicaltrials.gov when Tysabri was returned to market a trial was registered for Plasmorephis blood filtering to remove Trysabri from the body quickly whren it needed to be removed quickly. I was proud of myself for noticing when that trial was registed with the gov & watched it's successful completion.

” The patient, who was admitted to the hospital on October 24, underwent plasmapheresis to remove Tysabri from their system and was released from the hospital on October 28. The patient is currently under the care of the treating physician." No update yet on how she is doing. I had heard about a case of possible PML here in the US, last week, so I am assuming it is the same woman. Her husband posted about it on a site I found with people on Tysabri.

Last week when she went to the doctor, she was informed that patients who has been on the tysabri infustion for over two years have a greater chance of developing the brain infection PML. I believe she was told the odds went up to 1 in 800. However, she was also told that if she were to stop tysabri she was pretty much guaranteed to have an attack of the MS. She has an agressive form of MS and other medications don't seem to work.

Just an update on PML, for anyone who is currently considering Tysabri, or who may need to look at it in the future...the original 3 cases of PML were indeed initially considered to be due to the use of Tysabri in conjunction with other treatments for MS, particularly interferon.

Quix - I have wondered how someone without JCV acquired it. Is it airborne etc. Before starting Tysabri I tested JCV -. After 20 infusions I tested JCV +. Now I wonder if I had it earlier, at undetectable levels. It's a moot point for me, as at the same time it was determined that Tysabri was no longer working for me (fetuin-A CSF level). No point in risking PML if the Tysabri isn't working :-) I've moved on to rituximab.

The test tells if the person has been exposed to the JC Virus or not. PML on tysabri has only occured in people who are JC positive. There has not been a single case of PML in JC negative people. You can read the release here- http://www.medpagetoday.

Use of other immunosuppressants before Tysabri are a risk factor for PML, but this does not refer to the standard first line DMDs. Have you had any side effects in your time on Tysabri? It's great that your MRIs are stable! Have you talked to your neuro about remaining on Tysabri? Everybody is different, so there are a lot of factors that play into a decision to remain on it or stop. there is also the possibility of rebounding when stopping Tysabri that should be taken into account.

But the neuro also talked about Natiluzamab (tysabri) and the PML problems associated with it. The take aways were: PML occurs with other drugs/diseases too, but doesn't occur spontaneously. People with JC Virus negatives NEVER develop PML according to the stats. Most interesting to me was the idea that that European incidence rate of PML is hypothesized to be significantly greater because of the cost constraints of health care.

I just saw a MS neuro at OSU hospital. He asked me whether I was interested in being in the Tysabri study. I am only 37 and have only had one relapse. I know I will be deciding on a treatment and not sure what direction to go. This neuro is big in research and he spent a lot of time talking with me about MS. He mentioned a JC Virus and took my blood to look for it. If I don't, I would be a good candidate for Tysabri. It has 67% reduction in relapses but also risks getting PML.

My clinical exam was good and my brain MRI was free from evidence of PML and free from any new lesion activity. I have been having some issues with my left leg lately, beyond my 45 minute exercise wall. My left leg can sometimes have a mind of its own. If I walk down a hallway and turn right it wants to keep going straight, He seems to think that there may be some activity in my c/t-spine. He also thinks I will benefit from some PT.

I do not have typical ms, but a variant that is still clinically not diagnosed. I have a great neuro @ Stanford & he is recommending I start on Tysabri ASAP. I read up about the JC virus, and regardless plan to begin treatment next week. I don't know anyone with ms or ms variants so I want to know more about Tysabri from people who are on it or have used it. What is your experience? Pros/cons? I have read about side effects but I want to hear your thoughts & how it made you feel.

The risk associated with being JCV + and getting Tysabri is PML. PML is a rather nasty little brain infection. In addition to monitoring my blood for JCV, my doc also used MRI to watch for signs of PML. My MS dod not advance, nor did I have any relapses while on Tysabri. I stopped for 2 reasons. The first was that after initially being JCV -, I converted to JCV +. At the same time my doc was able to determine that Tysabri was no loger working.

I just completed my 41st Tysabri infusion the day before Thanksgiving. For me, since restarting the medication in October 2006, I have not had one single relapse nor any new lesions on my recent MRIs.

Hi Kat - I will get my 11th infusion in about 10 days. I have had no issues of any kind in conjunction with Tysabri. From the follow up MRI's I've had Tysabri seems to be doing the trick. No new lesions or relapses since I started. You will be tested for the JC virus prior to starting.

The JC virus test was developed as part of a clinical trial to hopefully gather enough information from many people to be able to help stratify the risk for PML when on Tysabri. At this point, though, there are no hard and fast answers. The assumption is that if you are JC positive, you stand the CHANCE of developing PML - it certainly doesn't mean you will develop it.

Novartis (the maker of Gilenya) at this point is attributing the PML to the prior Tysabri usage, but they acknowlege "that the contribution of Gilenya to this case can not be excluded." I figured I'd post this just as a heads up ... not trying to freak anyone out, just something to be aware of and keep an eye on. It will be interesting to see if this will be an isolated incident, or if there will be more cases to follow.

As of March 2008, more than 26,000 patients were on Tysabri® worldwide. Since the re-launch of Tysabri in July 2006, no new cases of progressive multifocal leukoencephalopathy (PML) have been reported. PML is an often-fatal viral infection of the brain. Data from the PLEX study suggest that plasma exchange may be an effective procedure for accelerating the removal of Tysabri from the blood if PML infection is suspected.
