Tysabri (natalizumab)

Tysabri (natalizumab), an approved treatment for forms of multiple sclerosis (MS), can be safely used during pregnancy or while breastfeeding, a study showed. “The findings of our observational study offer … relevant insight into the safety profile of [Tysabri] therapy not only during pregnancy but also during breastfeeding,”…

Treatment with Tysabri (natalizumab) may help delay disability progression in people with secondary progressive multiple sclerosis (SPMS) over Rebif (interferon beta-1a), an analysis of data from two clinical trials suggests. While the trials initially failed to demonstrate slowing disease progression, a significant benefit was observed when accounting…

Starting Tysabri (natalizumab) early in multiple sclerosis (MS) treatment may lead to better outcomes, including greater reductions in relapse rates and less use of MS-related healthcare services over starting it after other therapies. That’s according to a U.S. healthcare claims analysis of more than 1,500 adults with MS.

Tyruko (natalizumab), the first biosimilar of Tysabri, is now available in Germany for adults with highly active relapsing-remitting multiple sclerosis (RRMS). As a biosimilar, Tyruko has the same safety and efficacy profile, mechanism of action, and pharmacological properties as Tysabri. Biosimilars are typically sold at lower prices than their reference medication,…

Extending Tysabri (natalizumab) dosing intervals based on the drug’s blood levels was as effective at controlling disease activity in people with relapsing-remitting multiple sclerosis (RRMS) as the approved four-week dosing regimen. That’s according to results from NEXT-MS (NCT04225312), a Phase 4 clinical trial studying whether tailoring Tysabri’s…

People with multiple sclerosis (MS) who develop progressive multifocal leukoencephalopathy (PML) as a side effect of Tysabri (natalizumab) often see their neurological symptoms worsen severely during the infection and their disability gradually accumulate over time. That’s according to a study in Austria, which also showed that most disability progression…

People with multiple sclerosis (MS) tend to accrue more medical costs after switching to infusible therapies Ocrevus (ocrelizumab), Tysabri (natalizumab), or Lemtrada (alemtuzumab), according to an analysis of data from commercially insured patients in the U.S. “The overall healthcare costs for MS patients increased a lot…

Multiple sclerosis (MS) patients who started taking Tysabri (natalizumab) long after their diagnosis were found to have worsened disease progression. But those who began using it earlier showed less aggravated clinical and radiological outcomes of the disease than participants who started treatment later, a study showed. The study,…

People living with multiple sclerosis know that the medications used to treat it are expensive. According to the National Multiple Sclerosis Society, the median annual price of brand-name disease-modifying therapies (DMTs) last year was $91,835. Five of them carried a price tag of more than $100,000 a year. Many pharmaceutical…

Tysabri (natalizumab) infusions given in the home to people with relapsing-remitting multiple sclerosis (RRMS) save money and are more convenient, while apparently as safe and effective as those given in clinical settings, a pilot study comparing the two delivery methods reported. Nonetheless, its researchers recommended larger trials be…

People with relapsing multiple sclerosis (MS) have a better prognosis and a slower progression to disability since the introduction of disease-modifying treatments (DMTs) some 20 years ago, according to a retrospective study. The study, “Outcomes in a Modern Cohort of Treated Multiple Sclerosis Patients Followed from Diagnosis Up…

A new artificial intelligence (AI)-based model is better than conventional methods for detecting brain changes in response to treatment with Tysabri (natalizumab) in patients with relapsing-remitting multiple sclerosis (RRMS), a study reports. The study, “High-dimensional detection of imaging response to treatment in multiple sclerosis,” was published in…
