Smoking Increases Relapse Rate in RRMS Patients on Tysabri, Study Suggests

Smoking increases the relapse rate in patients with relapsing-remitting multiple sclerosis being treated with Tysabri , an observational study suggests. Multiple sclerosis is a multifactorial disease associated with both genetic and environmental risk factors.Ā Smoking, in particular, has been linked to numerous aspects of MS, including its development and progression. In a previous study, the research team looked at how smoking influences the relapse rate in RRMS patients being treated with interferon beta. From more than 800 patients, they found that smoking one pack per day (about 20 cigarettes) essentially interfered with the positive effect of the IFN-beta treatment and increased the relapse rate by 27%. The researchers then questioned whether the same was true for other treatments. Tysabri, developed by Biogen, is a monoclonal antibody that targets the alpha-4 integrin protein. By interfering with this molecule, the therapy prevents white blood cells from moving into the central nervous system, suppressing the immune reaction that contributes to MS symptoms. In the study, 355 Tysabri-treated RRMS patients from the Danish Multiple Sclerosis Centre were assessed. To gather information on smoking habits and body mass index, the patients filled out a 100-question survey. Data was collected between the start of the treatment and a two-year follow-up visit. Results showed that smoking one pack of cigarettes per day increases the relapse rate by 38% in RRMS patients on Tysabri. This increase in relapse rate takes into account both sex and age at the start of treatment, since ageĀ can affect the relapse rate. For example, an increase in age by one year raises the number of relapses by 2%. The researchers also looked at the relationship between smoking and the presence of two immune-related alleles:Ā HLA-DRB1*15:01 andĀ HLA-A*02:01. Previous studies showed that HLADRB1*15:01Ā is associated with an increased risk ofĀ developing MS, whileĀ HLA-A*02:01 is linked to a decreasedĀ risk. Although previous studies reported a link between smoking and these two alleles in MS patients, the current study did not find an association between smoking and carrying either of these alleles. Based on the results, the researchers concludedĀ that smoking significantly increases the relapse rate in RRMS patients receiving Tysabri. According to the team, the results "add important informationĀ that hopefully will sharpen the focus on the overallĀ harmful effects of smoking in MS patients."

Shorter Washout Period Lessens Relapse Risk When Switching from Tysabri to Gilenya in RRMS, Study Finds

Shortening the washout period to four weeks when switching from Biogenā€™s Tysabri to Novartisā€™ Gilenya is safe and reduces the chances of experiencing a disease flare in patients with relapsing-remitting multiple sclerosis (RRMS), a small Swiss study found. A four-week washout reduced the risk of having a disease relapse or an increase in disease activity, compared with an eight-week washout period, for two years after switching from Tysabri to Gilenya. Although TysabriĀ effectively slows worsening of MS symptoms and the appearance of disease flares, its use is under a strict risk management plan as it heightens the risk of developing a rare and life-threatening brain infection called progressive multifocal leukoencephalopathy, also known as PML. Some patients may switch to Gilenya, an alternative disease-modifying therapy for RRMS. Gilenya has been associated with a lower risk of PML infection and seen to reduce relapses, disability worsening, and the appearance of new brain lesions on clinical trials. It also is the only therapy approved by the U.S. Food and Drug Administration for children with MS as young as 10. When switching from Tysabri to Gilenya, it is important to consider the washout period, which is the period when the patient is taken off medications. If too long, it may lead to disease reactivation, which can be even stronger than before starting Tysabri. There is little evidence about the optimal length of washout periods, but a Phase 3 trial showed that an eight-week washout between Tysabri and Gilenya was beneficial compared with longer washouts of 12 or 16 weeks. The eight-week washout enabled more RRMS patients to become free from relapses and lowered disease activity. To study if a shorter washout period of four weeks further reduced the risk of MS reactivation, researchers conducted an open-label, observational study at the University Hospital, Basel, Switzerland. The study enrolled 25 RRMS patients who were appointed to switch from Tysabri to Gilenya. Participants were assigned to either a four-week or an eight-week washout period, and were followed for two years after switching to Gilenya. Although patients were older in the four-week washout group, disease activity and disability scoreswere not significantly different between groups at the beginning of the study. Relapses, disability scores, and disease activity on magnetic resonance imaging scans were recorded at baseline and weeks 8, 12, 16, 20 32, 56, and 108. In the first year (week 56) the proportion of patients with disease flare-ups or disease activity on MRI was not significantly different between the two washout groups, affecting 55.6% and 62.5% of the patients who had a four-week and an eight-week washout, respectively. However, at the end of the two-year follow-up (week 108), recurrent event analysis showed that patients who were on the four-week washout group were 77% less likely to experience relapses. The combined risk for relapse or disease activity on MRI also was 58% lower in the four-week group,Ā compared with those who had an eight-week washout. In addition, researchers found that patients who had flares more frequently in the year before discontinuing Tysabri also had a nearly four times higher risk of experiencing relapses in the first year after switching to Gilenya. ThisĀ suggests that the number of relapses before switching from Tysabri can predict disease reactivation once on other disease-modifying therapies. Both washout periods were deemed safe, with no serious adverse side effects or cases of opportunistic infections, including PML, being reported. Researchers emphasized, however, that the findings need to be confirmed in larger studies.
