Since I have no personal experience with either AMPYRA™ or 4-AP, I asked a couple of MS friends to share their stories. Please meet Connie and Melissa.
Connie’s Story:
Diagnosed with MS in 1999, Connie quickly learned that she has the primary progressive form of MS. Her initial symptoms include numbness in hands and feet, tingling in arms and legs, extreme fatigue and weakness. She was still walking unassisted in 2002 but by the end of 2005 needed hand controls for her vehicle and began using a walker, even after four courses of Novantrone.
In Rheumatoid Arthritis and Sjögren’s Syndrome, we discussed how patients living with RA have an increased risk of developing secondary Sjögren’s Syndrome (SS). Early diagnosis and treatment are important for the prevention of complications in Sjögren’s. However, reaching a diagnosis can often be difficult and may take an average of six and a half years from the onset of symptoms, according to the Sjögren’s Syndrome Foundation.
Sjögren’s syndrome symptoms frequently overlap with or “mimic” those of other diseases including lupus, rheumatoid arthritis, fibromyalgia, chronic fatigue syndrome and multiple sclerosis. Dryness can also occur for other reasons, such as a side effect of medications such as anti-depressants and high blood pressure medication.
There is no single test that will confirm diagnosis. Your doctor will base a diagnosis on medical history, physical exam, combination of symptoms, and results from clinical and laboratory tests. A rheumatologist is often responsible for diagnosing and managing Sjögren’s Syndrome. Criteria for diagnosis considers dryness symptoms, changes in salivary (mouth) and lacrimal (eye) gland function, and systemic (whole body) findings.
The U.S. Food and Drug Administration has approved the marketing of Ampyra™ (dalfampridine, formerly known as fampridine SR, from Acorda Therapeutics) for its ability to improve walking speed in people with any type of multiple sclerosis. This is the first therapy specifically approved to treat a symptom of MS, and it represents a big step forward for the many people who may benefit.
Comment: “The FDA’s approval of Ampyra is wonderful news for many people with MS who experience problems with walking,” said John R. Richert, MD, Executive Vice President for Research & Clinical Programs at the National MS Society. “This brings a welcome symptomatic therapy that may restore some function and make a real difference in quality of life for a large number of people with different types of MS.” Further study and clinical practice may help determine the extent to which the drug may impact other functions not measured in the clinical trials, and provide hints as to which individuals are most likely to respond.
Q. What is Ampyra? (pronounced ahmPEERah)
A. Ampyra, formerly known as fampridine SR, is a tablet containing a sustained-release formula of 4-aminopyridine, which blocks tiny pores, or potassium channels, on the surface of nerve fibers. This blocking ability may improve the conduction of nerve signals in nerve fibers whose insulating myelin coating has been damaged by MS. The first studies of this potassium-blocking approach in people with MS were supported by the National MS Society.
Q. How is a “symptomatic therapy” different from the approved disease-modifying therapies for MS?
A. A symptomatic therapy is usually a drug that addresses a particular aspect of a disease, but taking it does not change the underlying course of the disease or limit the damage caused by the disease. There are many medications taken by people with MS to manage specific symptoms, such as spasticity, fatigue or depression. While there are FDA-approved disease-modifying therapies that are partially effective against some forms of the disease, as well as rehabilitation and symptomatic treatments for some symptoms, until now there was no pharmacologic treatment available for MS-related difficulty walking.
Q. How common are walking problems among people with MS?
A. A recent survey among more than 1,000 individuals with MS and many of their family members examined the impact of difficulty walking on quality of life among people with MS and their families. Some two-thirds of patients reported difficulty walking and of these, 70% reported that such difficulty was the most challenging part of their MS, and most reported that difficulty walking restricts their daily activities significantly, including their ability to travel. (Read more about survey results)
Q. How Effective is Ampyra?
A. Two phase III clinical trials of the drug were sponsored by Acorda Therapeutics. In the first, involving 301 people with any type of MS, walking speed increased by 25% compared with placebo. Results of this study have been published (February 28, 2009 issue of The Lancet (2009 373;732-738, summarized here. Results from a later, second phase III study involving 240 people with MS, announced in 2008, confirmed the benefits seen in the first, finding that a significantly greater proportion of people on the therapy had a consistent improvement in walking speed compared to those who took placebo. Among those taking Ampyra who improved in walking speed, there was a statistically significant improvement in leg strength.
Q. What are the potential side effects of Ampyra?
A. In the first phase III study, common adverse events (side effects) experienced more often by those on active treatment included back pain, dizziness, insomnia, fatigue, nausea and balance disorder. Two serious adverse events led participants to discontinue taking the drug (one case of anxiety and one seizure in a person who developed sepsis from a urinary tract infection). In the second phase III study, additional common adverse events in those on therapy included urinary tract infection, falls, and headache.
Q. How is Ampyra taken?
A. In clinical trials, participants on active therapy took one tablet of the drug by mouth two times per day. According to a company press release, Ampyra will be taken two times a day, approximately 12 hours apart.
Q. When and how will Ampyra become available for prescription?
A. According to the sponsor, Ampyra is expected to be ready for prescription by March 2010. The drug will be distributed through a network of specialty pharmacies and coordinated by a team providing support services to facilitate access to the drug for patients and healthcare providers.
Q. Who might benefit from taking Ampyra?
A. There is no way of knowing in advance whether any particular individual who has MS might benefit from taking Ampyra. In clinical trials, a proportion of people with all types of MS were found to benefit in terms of walking speed. This proportion ranged from 35% to 43% of those who took the drug in the two phase III clinical trials.
Q. Can anyone with MS take Ampyra?
A. Ampyra was approved for persons with any type of multiple sclerosis. However, the FDA’s approval of Ampyra comes with the warning that the drug should NOT be taken by individuals with a history of seizures, or by those with moderate to severe renal impairment (CrCl 51–80 mL/min).
Q. What is renal impairment, and why is it important that those taking Ampyra have adequate renal function?
A. “Renal” refers to the kidneys, which in essence clean the blood. If a person has adequate kidney function, then Ampyra will be cleared from the blood to a sufficient degree between doses so as to maintain a steady drug level in the blood. If a person has moderate to severe kidney impairment, then there is a danger that the concentration of the drug will increase in the blood beyond the amount considered safe. The result could be increased side effects including seizures, which in clinical trials occurred infrequently. For the same reasons, Ampyra should not be taken in combination with other forms of 4-aminopyridine (4-AP, fampridine), since the active ingredient is the same.
Q. Will taking Ampyra make it possible to stop using my walking aids?
A. There are many different types of walking aids and they address many different types of movement issues, so there is no single answer to this question. It is important that people who try the drug NOT make changes related to walking aids until they determine whether and how the drug affects them. One concern is that in the second clinical trial, a side effect experienced by some participants was increased falling. For that reason, it is important that people taking this medication continue to use caution and discuss any proposed changes in walking aids with their health care provider.
Q. What will Ampyra cost?
A. At the present time, no information has been released about how much Ampyra therapy will cost. The company expects to release that information in coming weeks.
Q. Will Ampyra be covered by my health insurance plan?
A. Coverage for Ampyra will depend on individual insurance plans. Acorda has established a team to provide support services to help patients and healthcare professionals access the drug, including working with insurance carriers and providing patient assistance programs, details of which will be available in coming weeks.
If you have multiple sclerosis (MS), the nerves in your brain and spinal cord slowly lose their coating. Over time, these nerves get damaged and may stop working properly. This can affect you in all sorts of ways. The most common symptoms are feeling very tired and weak and having numb or 'tingling' areas.
The most common type of MS is called 'relapsing remitting multiple sclerosis'. This means you have periods without any symptoms, then periods when you get a flare-up of symptoms, called a relapse. The condition is caused by a problem with the immune system, which mistakenly attacks the coating of the nerves. So, most treatments work to change the way your immune system works.
The treatment used most often is called beta interferon. It has to be injected. It's intended to reduce the number of relapses you have, and prevent you from becoming disabled. But it doesn't work for everyone. In studies, around 55 in 100 people still had a relapse over the course of two years, despite taking beta interferon. Another injected treatment, glatiramer acetate, works about as well as beta interferon.
Doctors have been investigating new drugs for MS that can be taken as tablets, instead of injected. We now have results from three big trials (each with over 1000 patients) looking at how well they work. The new drugs studied are called fingolimod and cladribine.
What do the new studies say?The studies show that these new drugs work better than no treatment, and one of them works better than beta interferon.
Three studies have been published. They compare:
Both drugs were tested at two different doses. Higher doses worked slightly better for fingolimod, but there wasn't much difference between high and low doses of cladribine. People were more likely to get unwanted side effects with higher doses.
The side effects were serious in some cases. Two people taking fingolimod died after catching serious herpes virus infections. Four people had breast cancer, and five had a type of skin cancer. People taking cladribine were also more likely to have serious infections or cancers than people taking placebo pills. Overall, serious problems affected 8 to 9 percent of people taking cladribine and about 5 to 10 percent of people taking fingolimod.
People taking drugs that affect the immune system are at higher risk of infections and cancers, because their immune system is weakened by the drugs. Both these drugs reduce the amount of white blood cells (lymphocytes), which protect against infection.
How reliable are the findings?The findings from these studies should be reliable. They were carried out as randomised controlled trials, which is the best way to find out whether a treatment works. It's important not to compare the results between trials, though (for example, to compare fingolimod with cladribine), because different groups of patients can have different results. We can see this in the difference in numbers of patients having relapses between the two studies that included a placebo drug.
Also, it's important to remember that these studies lasted only one or two years. We need to see long-term results, especially to find out whether they are safe to take for longer than two years.
Where do the studies come from?Both drugs have been tested by international groups of researchers and doctors, some of whom worked directly for the drugs companies that make the drugs (Novartis Pharma for fingolimod and Merck Serono for cladribine). It's common for drugs companies to fund research into their own drugs, especially while they are under development. The studies were published in the New England Journal of Medicine.
What does this mean for me?If you have multiple sclerosis, you'll be keen to hear about any new treatments that might help your condition. But these drugs have not yet been licensed and so will not be widely available yet. If and when they are licensed, they may be more suitable for some people than others. You'll need to weigh up the risks of getting serious side effects, with the potential benefits of fewer relapses.
What should I do now?If you are interested in finding out about research into new MS drugs, speak to your specialist or to the Multiple Sclerosis Society (http://www.mssociety.org.uk/research/index.html).

Oral Therapy for Multiple Sclerosis — Sea Change or Incremental Step?
William M. Carroll, M.B., B.S., M.D., F.R.A.C.P.
The long-awaited arrival of oral formulations for the treatment of relapsing–remitting multiple sclerosis is welcome news for the estimated 2.5 million people worldwide who have this chronic, disabling disease. Since the publication of the first pivotal trial of interferon beta-1b in 1993, practitioners and patients alike have been anticipating the approval of oral therapies because of the relative ease of administration, which should improve adherence and reduce restrictions on lifestyle.
In this issue of the Journal, researchers report the results of three well-conducted trials of the first two oral agents, cladribine and fingolimod, in the treatment of multiple sclerosis. The researchers studied cladribine in the Cladribine Tablets Treating Multiple Sclerosis Orally (CLARITY) trial and fingolimod in the FTY720 Research Evaluating Effects of Daily Oral Therapy in Multiple Sclerosis (FREEDOMS) trial and the Trial Assessing Injectable Interferon versus FTY720 Oral in Relapsing–Remitting Multiple Sclerosis (TRANSFORMS). Although these two drugs differ in their mechanisms of action, both reduce the number of potentially autoaggressive lymphocytes that are available to enter the central nervous system. The articles, which report that the agents are effective and have manageable adverse- effect profiles, raise three questions: How do these therapies measure up against the existing treatments? Are all the longer-term adverse effects known? What do these drug trials tell us about multiple sclerosis and our treatment goals?
Both cladribine (in the CLARITY trial) and fingolimod (in the FREEDOMS trial) were highly effective against placebo over a 2-year period, and fingolimod was more effective than intramuscular interferon beta-1a over a 12-month period (in the TRANSFORMS trial). Each of the three studies involved more than 130 centers in up to 32 countries, and the enrollments of 1272 to 1326 patients ensured that the trials were sufficiently powered to detect an effect of two doses of the active oral agent. Patients had active relapsing disease with durations of 7 to 9 years. On the Expanded Disability Status Scale (which ranges from 0 to 10, with higher scores indicating greater disability), patients had a median score of 2.0 in the fingolimod trials and mean scores ranging from 2.9 to 3.0 in the cladribine trial.
All three studies used the annualized rate of relapse as the primary end point, and high and low doses of cladribine and fingolimod were shown to be superior to both placebo and interferon beta-1a. For cladribine versus placebo, the relative risk reduction in the annualized relapse rate was 57.6% for the group receiving 3.5 mg per kilogram of body weight and 54.5% for those receiving 5.25 mg per kilogram. For fingolimod versus placebo, the relative risk reduction was 54% for the 0.5-mg dose and 60% for the 1.25-mg dose. For fingolimod versus interferon beta-1a, the relative risk reduction was 52% for the 0.5-mg dose and 39% for the 1.25-mg dose. Both agents were superior to the comparators with respect to secondary end points, including measures on magnetic resonance imaging and a number of clinical end points, including the time to the progression of sustained disability at 3 months.
Furthermore, although only fingolimod was tested against the widely used interferon beta-1a, it is likely that the two oral therapies will be at least as effective as other currently available disease- modifying therapies. In this regard, head-to-head trials of subcutaneous interferon beta-1b and interferon beta-1a versus intramuscular interferon beta-1a showed advantages of both subcutaneous regimens over the latter. More recent trials were unable to separate the clinical efficacy of the two subcutaneously administered forms of interferon beta from that of glatiramer acetate.
Adverse effects were similar in all three trials of cladribine and fingolimod, and rates of events leading to discontinuation of a study drug were low but still at least twice as frequent with highdose cladribine (7.9% for the 5.25-mg dose) and fingolimod (10% and 14% for the 1.25-mg dose). Herpetic infections occurred among patients receiving both cladribine and fingolimod. The rate of herpes infections among patients receiving the 1.25-mg dose of fingolimod was 5.5%; such infections were serious in three of these patients, two of whom died. Twenty cases of cutaneous herpes zoster were recorded among patients receiving cladribine, three of which were serious. Three solid tissue cancers (pancreatic, ovarian, and melanoma) occurred among patients receiving lowdose cladribine (3.5 mg per kilogram). Basal-cell carcinoma, melanoma, and breast cancer were all more common among patients receiving fingolimod than among those receiving interferon beta-1a. Macular edema was confirmed in 13 patients, 11 of whom received high-dose fingolimod (7 in the FREEDOMS trial and 4 in the TRANSFORMS trial). Of these 13 patients, 11 recovered within 1 to 6 months after discontinuation of therapy, and the condition of the other 2 patients stabilized. Transient bradycardia and first- and second-degree heart block occurred more frequently among patients receiving high-dose fingolimod than in the comparator groups. Lymphocytopenia was frequent in patients receiving both agents, more so with higher doses. Clinicians and patients will need to evaluate the risks and benefits of each of these drugs. Given the recent studies documenting the development of progressive multifocal leukoencephalopathy among patients receiving natalizumab, a monoclonal antibody against α4-integrin, close postmarketing surveillance will be important to detect any increase in these or other unexpected adverse effects.
The mechanism of action of both oral agents represents a major change from those of currently available drugs for multiple sclerosis. Among a number of actions that are claimed for current therapies is that they change the emphasis of the immune response from activation of proinflammatory type 1 helper T cells to activation of antiinflammatory type 2 helper T cells. Even though cladribine is administered in two or four short courses annually, whereas fingolimod is given daily, both drugs were associated with persistent lymphocytopenia. Cladribine is resistant to the enzyme adenosine deaminase, which causes an accumulation of toxic deoxyribonucleotides in lymphocytes, resulting in relatively selective longterm depletion of CD4+ and CD8+ T cells. Fingolimod is a synthetic analogue of myriocin that is derived from a fungus (Isaria sinclairii). Once phosphorylated, the drug acts to down-regulate the sphingosine-1-phosphate receptor required for antigen-activated lymphocytes to egress, effectively locking them in the nodes. Thus, both cladribine and fingolimod are targeting inflammation, the key driver of immune injury in multiple sclerosis. Similarly, both natalizumab, which blocks lymphocyte access to endothelium in the central nervous system, and the anti-CD52 monoclonal antibody alemtuzumab, which destroys T and B cells, have shown impressive reductions in disease activity. Insights from these trials and others treating the initial stages of disease suggest that early direct targeting of the immune system offers the best hope for the prevention of later disability.
The studies in this issue of the Journal provide a new horizon for patients with relapsing–remitting multiple sclerosis and a welcome increase in the range of treatment options. Although current therapies remain very effective, particularly when they are administered early, and have welldefined side-effect profiles, oral therapies further support a change in treatment approach to directly prevent immune-mediated injury. This approach will probably be followed until the next step in the therapeutic advance occurs, but such a change in strategy highlights the final question: What are the long-term goals of this new phase of therapy?
The question will not be fully answered until the underlying cause of multiple sclerosis is better understood, but the lack of a definable end point remains a contentious issue for clinicians and health care funders alike. Time will determine the long-term effectiveness of these treatments in delaying the development of irreversible disability, and as ongoing, real-life experiments, they will contribute to our understanding of this enigmatic disease.

In addition to MS organizations who are focused on research and registries, we have several organizations which offer support and services to folks affected by multiple sclerosis. The following provides an introduction to the services provided by the more prominent nonprofit organizations in the United States which serve on a national level.
National Multiple Sclerosis Society
Living with MS means the road to wellness is more than treatment of the disease. Equally important are health and wellness strategies, a strong support network of family and friends, satisfying work and leisure activities, a meaningful place in the community, and adequate attention to one's inner self.
The National MS Society offers an extensive variety of programs, services and resources for people living with MS, including family members, caregivers and other members of their support systems. Local Society chapter programs vary from one community to another. To learn more about all of the programs offered in your community, please contact your chapter.
Prescription Medications
1. Ask for easy-to-open medication bottles. Prescription bottles can be difficult to manage when you have RA hands. If you have trouble removing childproof lids on prescription bottles, ask your pharmacist to replace them with easy-to-open lids. These will take much less effort to open and put less strain on delicate hands and fingers. However, if you have children in the house, you will need to be especially careful to store your medications in a place which is safely out of children’s access.
2. Organize medications in daily and weekly containers. Go a step beyond the easy-to-open lids and organize your medications in weekly containers, the molded plastic type which are available at most pharmacies or discount stores. These containers with snap-lock hinged lids come in 7-compartment, 14-compartment, or even 28-compartment configurations. You can choose one day a week during which to fill the compartments with your medications and not have to open those tricky childproof lids for another week.

Updated January 7, 2010
Summary: Recent reports are calling attention to the idea that a phenomenon called CCSVI, a reported abnormality in blood drainage from the brain and spinal cord, may contribute to nervous system damage in MS. This hypothesis has been put forth by Dr. Paulo Zamboni from the University of Ferrara in Italy. Based on the results of his initial preliminary findings, Dr. Zamboni states that this pilot study warrants a subsequent larger and better controlled study to definitively evaluate the possible impact of CCSVI on the disease process in MS.
It has been proposed by Dr. Zamboni, but not yet proven, that CCSVI may be corrected through endovascular surgery, which involves inserting a tiny balloon or stent into blocked veins in order to permit the flow of blood out of the brain and spinal cord, a procedure that has been called “liberation therapy” in some reports.
UPDATE: The National MS Society is undertaking the funding of new research on CCSVI in MS and has invited investigators worldwide to apply for grants that would explore this lead. In response to a January 6 deadline, the National MS Society and the MS Society of Canada received numerous letters of intent from investigators from seven countries. These letters of intent, which briefly describe the proposed research, will be reviewed and those that meet grant guidelines will be invited to submit full research proposals.
CCSVI Research Funding Timeline
January 12, 2010 – Investigators whose letter of intent meet guidelines are invited to submit full research proposals with a deadline of February 9, 2010.
May 2010 – International panel of experts conducts an expedited review of all applications received through this special request for applications.
June 2010 – Funding decisions announced.
July 1, 2010 – Anticipated start date for funding of any successful research applications.
The applications will undergo an accelerated review process by an international panel being convened in cooperation with other MS Societies to ensure an expedited, coordinated response. If this hypothesis is confirmed, it may open up new research avenues into the underlying pathology of MS and new treatment approaches to therapy.
Background: In a recent study by Dr. Zamboni and colleagues, the team evaluated abnormalities of blood outflow in major veins draining from the brain and spinal cord to the heart in 65 people with different types of MS, compared with 235 people who were either healthy or who had other neurological disorders. They used sophisticated sonography techniques to detect abnormalities of venous drainage. The investigators reported evidence of slowed and obstructed drainage in the veins draining the brain and spinal cord in many of those with MS. They also found evidence of the opening of “substitute circles” – where the flow is deviated to smaller vessels to bypass obstructions, and these were often found to have reverse flow (reflux) of blood back into the brain.
The investigators call this venous obstruction “chronic cerebrospinal venous insufficiency,” or CCSVI. The treatment status of the people with MS (i.e., whether or not they were on an MS disease modifying drug) did not appear to influence whether they showed signs of CCSVI. The authors speculated that the reverse flow of blood back into the brain might set off the inflammation and immune-mediated damage that has been well described in MS. This study was published in June 2009 (J Neurol Neurosurg Psychiatry 2009; 80:392-399).
It is proposed, but not yet proven, that CCSVI may be corrected through endovascular surgery. This surgery is being called “liberation therapy” in some reports. One study getting underway was described at the 2009 ECTRIMS meeting in September. It involves a collaboration between researchers in Italy, Buffalo (NY) and Birmingham (AL) who are attempting to treat venous obstruction in 16 individuals using balloon dilation such as has been used for many years to treat blocked arteries.
In a small, open-label study by Dr. Zamboni and colleagues published in December, the team evaluated the safety and preliminary outcomes of vascular surgery (percutaneous transluminal angioplasty) in 35 individuals with relapsing-remitting MS, 20 with secondary-progressive MS, and 10 with primary-progressive MS. (J Vasc Surg 2009; 50:1348-1358) They reported some positive impacts and suggested that controlled trials were necessary to better determine potential safety and benefits of this procedure.
Next Steps: The National MS Society has prompted communications between MS Societies worldwide and leveraged resources to ensure an open exchange of information and a coordinated and expedited approach to conducting and evaluating additional research on CCSVI. On December 16, 2009, the Society released a worldwide Request for Applications to the scientific community to explore CCSVI, and is collaborating with the MS Society of Canada and possibly other societies to convene an international panel of experts to conduct an accelerated review of proposals. We are also working with our sister MS Societies around the world to assure that our research strategies are coordinated. Through an internationally coordinated and expedited review process, new CCSVI research projects are expected to begin July 1, 2010. (See Research Funding Timeline above for more details.)
According to the Buffalo Neuroimaging Analysis Center, although 500 subjects have already been selected for their initial combined transcranial and extracranial venous doppler evaluation study, they are still seeking participants for a larger-scale clinical study with the aim of evaluating the prevalence of venous obstruction in people with MS. This study does not involve treatment of obstructions.
To get the quickest answers and most reliable results about benefits and risks of any surgical procedure that might attempt to address blood flow in or out of the brain, it is crucial that such surgery be performed only as part of controlled trials, especially since there have been anecdotal reports of surgical attempts to treat CCSVI in people with MS resulting in adverse events, including one reported death.
Many questions remain about how and when this phenomenon might play a role in nervous system damage seen in MS, and at the present time there is insufficient evidence to prove that this phenomenon is the cause of MS.
Frequently Asked Questions About CCSVI and MS
Q: What is the National MS Society’s view of CCSVI?
A: In trying to find the cause and more effective treatments for a disease as complex and unpredictable as multiple sclerosis, the Society is steadfast in its commitment to pursue all promising avenues of research that can lead to improved treatments and ultimately, a cure. It is important for researchers to think outside the box and we believe Dr. Zamboni has done this. His hypothesis is a path that must be more fully explored and Dr. Zamboni himself has stated that additional research is essential to evaluate it.
Q: Will the National MS Society fund research into CCSVI in MS?
A: The National MS Society is pursuing follow-up research in how CCSVI might be involved in the MS process and we have invited investigators from around the world whose research is relevant to MS to submit proposals to apply for grants that would explore this lead. These applications will undergo an accelerated review process.
Q: Do the reports of a possible association between insufficient vein drainage and MS mean that MS is caused by venous insufficiency?
A: No. Based on results published about these findings to date, there is not enough evidence to say that obstruction of veins causes MS, or to determine when this obstruction may occur in the course of disease.
Q: If CCSVI turns out to be important in MS, can it be treated?
A: No one knows yet. Surgical procedures for CCSVI in MS are still experimental and should be undertaken only as part of formal clinical trials that include all of the standard safeguards that are followed in such trials.
Q: How can I get involved in research on CCSVI in MS?
A: A larger-scale clinical study is getting underway in Buffalo, New York and is now recruiting participants nationwide with the aim of evaluating the prevalence of venous obstruction in people with MS. This study does not involve treatment of venous obstructions.
Q: I have MS. Should I be tested for signs of CCSVI?
A: We do not recommend testing for signs of CCSVI unless you are involved in a research study exploring this phenomenon, since at this time there is no proven therapy to resolve any abnormalities that might be observed, and it is still not clear whether relieving venous obstructions would be beneficial.
Q: Does CCSVI make the standard treatments of MS meaningless?
A: No. There is ample evidence proving that the FDA-approved therapies for MS provide benefit for people with most forms of MS.


Multiple sclerosis is often misunderstood, and for many people, the very name suggests things like permanent disability and visions of wheelchairs. The truth is that MS is a manageable disease, and a great many people with MS live active, fulfilling lives. That said, the progression of multiple sclerosis differs from person to person, so it's hard to gauge how the disease will affect each individual.
