Seven years after it first denied the request, the U.S. Food and Drug Administration accepted for review EMD Serono’s resubmitted New Drug Application (NDA) for cladribine tablets (brand name Mavenclad) as a treatment for patients with relapsing forms of multiple sclerosis (MS). The regulatory agency agreed EMD…

Oral DMTs Still Common 1st Therapy for New MS Patients but Ocrevus Having Impact, Market Report Says Deciding on what therapy to use is a tough decision for people with MS and their doctors. That’s especially true for someone who is newly diagnosed. Do you go with…

Cladribine tablets added to interferon-beta treatment significantly reduced the probability of relapses over 96 weeks in people with active relapsing multiple sclerosis , a Phase 2 clinical trial found. But a troubling diminishment in key immune cells was also seen in treated patients. Relapsing-remitting MS is marked by periods of flares caused by inflammatory attacks, followed by periods of partial or complete recovery . A majority --about 65 percent -- go on to develop secondary progressive MS. Despite the growing number of treatment options — including disease-modifying therapies — for these MS patients, efforts continue into better ways to lower relapse frequency and slow disease progression. Researchers tested the safety and efficacy of cladribine tablets as an add-on therapy in patients continuing to experience active relapses while under interferon-beta treatment. Cladribine is an oral medication that works by selectively targeting and reducing the number of immune cells involved in the inflammatory attacks occurring in active MS. It was developed by EMD Serono (Merck KGaA outside the U.S. and Canada) and approved in the European Union using the brand name Mavenclad (it is not approved in the U.S. for MS). Interferon-beta works by balancing pro- and anti-inflammatory signals, reducing the number of immune cells and promoting the survival of nerve cells. Interferon-beta therapies are marketed under several brand names; in the study, researchers analyzed patients using Rebif (marketed by EMD Serono), Avonex (by Biogen), and Betaseron/Betaferon (by Bayer). The 96-week, randomized, double-blind, Phase 2b trial called ONWARD enrolled a total of 172 patients with active relapsing MS, who were randomly divided into two groups: those given cladribine tablets together with interferon-beta, and those that received a placebo and interferon-beta. Results showed those taking cladribine tablets together with interferon-beta had 63% lower likelihood of a relapse compared to those given an add-on placebo. Add-on cladribine treatment also reduced most measures of disease activity as assessed by magnetic resonance imaging (MRI) — namely, the number of new brain and spinal cord lesions. However, almost half of patients in this treatment group developed lymphopenia, a condition where the levels of lymphocytes (important immune white blood cells) in the blood are abnormally low. None in the control group developed the condition. Other reported side effects, including other serious adverse side effects, were identical in the two groups. Altogether, the findings indicate that a cladribine and interferon-beta combination can successfully lower the probability of relapses over the course of 96 weeks, but also increase a person's chances of lymphopenia.

Oral disease-modifying therapies (DMTs) are the most common first choice of treatment for people newly diagnosed with multiple sclerosis (MS) in the United States, an analysis reports. Antibody-based DMTs like Ocrevus, however, are emerging competitors. Spherix Global Insights, a market research and analysis company, states that 1 in every…

Shortening the washout period to four weeks when switching from Biogen’s Tysabri to Novartis’ 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 Tysabri 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, 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. This 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.
