Natalizumab

Many decisions to stop taking the multiple sclerosis treatment Tysabri (natalizumab) appear to be based largely on subjective factors such as patients’ or physicians’ view of the risk, rather than objective assessments of the risk, a study indicates. Tysabri is an approved immunotherapy for active relapsing-remitting multiple sclerosis (RRMS). Despite its benefits, there…

The latest results on Tecfidera (dimethyl fumarate) and Tysabri (natalizumab) use in a clinical practice setting suggest that early treatment can improve outcomes in multiple sclerosis (MS) patients. This and other recent data on Tecfidera and Tysabri for the treatment of MS will be presented by Biogen at the…

Progressive multifocal leukoencephalopathy (PML) in multiple sclerosis (MS) patients treated with Tysabri (natalizumab) is linked to better outcomes if the condition does not give rise to actual symptoms and is diagnosed early. Limited brain lesions and more protective immune responses were also seen in patients who fared better, but researchers…

An indirect comparison of results from randomized clinical trials in relapsing-remitting multiple sclerosis (RRMS) patients suggests that Tysabri (natalizumab) is more effective than Gilenya (fingolimod) at reducing disease activity. The study, “The Efficacy of Natalizumab versus Fingolimod for Patients with Relapsing-Remitting Multiple Sclerosis: A Systematic Review, Indirect…

Multiple sclerosis patients are at risk of developing lymphopenia, or abnormally low levels of immune defense white blood cells, called lymphocytes, according to a study that investigated lymphocyte counts in people with relapsing MS both before and after the start of treatment. The study, “Lymphopenia in treatment-naive relapsing multiple…

Although Tysabri (natalizumab) is a highly effective in treating patients with relapsing-remitting multiple sclerosis (RRMS), some may develop progressive multifocal leukoencephalopathy (PML). According to a new study, this occurs because Tysabri impairs immune surveillance in the central nervous system and reactivates the latent John Cunningham polyomavirus (JCV). The study, “Natalizumab Affects…

Disease-modifying therapies, a group of treatments for people with relapsing-remitting multiple sclerosis (RRMS), work to stabilize patients’ cognitive functions just as they do their physical symptoms. Research, conducted over the course of a year, also reported no differences between two types of DMTs, Gilenya (fingolimod) and Tysabri (natalizumab). The study, “…

Never having been offered, let alone received any disease modifying therapy, I can address the subject of disease modifying therapies, and their side effects, with complete impartiality. Of course, the reason for the lack of any medication is because none has yet been approved for use with MS patients who…

Results from the STRIVE study support the safety of natalizumab (Tysabri) as a therapy for multiple sclerosis (MS) patients.

Mabthera (rituximab), a widely approved drug for treating lymphoma and/or rheumatoid arthritis, is highly effective in treating multiple sclerosis (MS), researchers reported in an observational study in Sweden, where Mabthera is increasingly being used outside of its approved indications to treat relapsing-remitting MS patients. The study, published in the journal…

A range of new multiple sclerosis (MS) data from Biogen will be revealed at the 68th annual meeting of the American Academy of Neurology (AAN) in Vancouver, Canada, on April 15–21. Presentations will include studies on Tecfidera (dimethyl fumarate), one of the most frequently used oral MS treatments worldwide, as well as several other…

Mice with experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), were found to have milder symptoms if the target of natalizumab (Tysabri) — VLA4 — was absent on B-cells, preventing regulatory cells that might control immune processes from entering the brain. B-cells are increasingly thought to play…

Natalizumab (Tysabri) harnesses multiple sclerosis (MS) activity by targeting CD49, a molecule on the surface of immune cells. Now, researchers found that the drug reduces the factor on regulatory T-cells to a greater extent than on inflammatory T-cells — a mechanism that might explain disease exacerbation during treatment. The molecule under…

Certain therapies used to treat multiple sclerosis (MS) have been associated with opportunistic infections of the central nervous system, including progressive multifocal leukoencephalopathy (PML), a rare but often fatal brain disorder caused by the John Cunningham (JC) virus. The question of whether the risk for opportunistic infections to MS patients outweighs…

Multiple sclerosis (MS) patients treated with natalizumab have an increased risk of developing high levels of antibodies associated with a virus causing a rare, but often fatal, brain infection known as progressive multifocal leukoencephalopathy (PML), researchers reported. Their study, “Therapy with natalizumab is associated with high JCV seroconversion and rising JCV index values,”…

Researchers from Karolinska Institute, Sweden, reported that the immune-associated protein lipocalin-2 (LCN2) is increased in multiple sclerosis, particularly in patients with progressive MS. The researchers, however, concluded that the factor cannot be used as a biomarker for the disease. The study, “Lipocalin-2 is increased in progressive multiple sclerosis…

The Multiple Sclerosis Society of New Zealand (MSNZ) announced that PHARMAC has agreed with its request to finance two novel first-in-line therapies for relapsing-remitting forms of multiple sclerosis (MS), making them accessible to patients there. PHARMAC recently agreed to fund the two treatments, teriflunomide (Aubagio), supplied by Sanofi-Aventis NZ, and dimethyl fumarate (Tecfidera),…
