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.

Two multiple sclerosis medications that are both popular and expensive are on a new list that U.S. regulators hope will increase price competition. The medications are Ampyra (dalfampridine), made by Acorda, and Tecfidera (dimethyl fumarate), by Biogen. They’re included on a list of more than 50…

Sanofi Genzyme and Principia Biopharma have entered into a license agreement to advance the clinical development of PRN2246, an oral drug candidate for the treatment of multiple sclerosis and other diseases of the central nervous system. PRN2246 is an inhibitor of the Bruton’s tyrosine kinase, an enzyme encoded by the BTK gene that plays a crucial role in B-cell development and the B-cell signaling pathway. B-cells are known to be involved in the development of autoimmune diseases that affect the nervous system, including multiple sclerosis. PRN2246 is an orally available therapy designed to easily access the central nervous system (brain and spinal cord) by crossing the blood-brain barrier, and impact the signaling of immune cells and brain cells involved in autoimmunity and inflammatory processes. The drug is designed to safely and effectively modulate B-cell function without depleting these cells. A Phase 1 clinical trial is now testing the drug's safety in healthy volunteers. Under the agreement, which is expected to close shortly, Principia will grant Sanofi an exclusive, worldwide license to develop and commercialize PRN2246. Principia, in return, will receive $40 million in upfront payments from Sanofi, and future milestone payments could reach $765 million. Principia will retain the option to co-fund the treatment's Phase 3 development in exchange for other royalties in the United States. Principia has developed a novel way to design and develop better and safer therapies based on oral small molecules. The company uses its proprietary Tailored Covalency technology to develop its drug candidates, which are, according to the company's website, safer, and more selective, potent and durable than other available treatments. The terms of this licensing agreement are still subject to customary regulatory approval.

RedHill Biopharma has received a Notice of Allowance for a new patent on RHB-104 its potential therapy for patients with relapsing-remitting multiple sclerosis (RRMS).

RHB-104 is a proprietary, orally-administered antibiotic combination with potentially potent intracellular, antimycobacterial…

New data on how Lemtrada and Aubagio perform in a real-world setting will be the focus of Sanofi Genzyme when the company showcases its research at the upcoming 7th Joint ECTRIMS-ACTRIMS Meeting in Paris this week. Researchers will also share information about the safety of a new investigational therapy, GLD52 (GZ402668), currently in a Phase 1 safety study. The TOPAZ study is one of the main data sources for the upcoming presentations. The study, which follows relapsing MS patients who participated in the CARE MS-I and CARE MS-II extension study , is a rich source of information on long-term outcomes. Researchers will share various aspects of disease outcomes and magnetic resonance imaging (MRI) data from patients followed up to seven years, with some presentations focusing solely on those who switched from treatment with interferon beta-1a. Among the Lemtrada highlights are findings demonstrating that Lemtrada does not appear to trigger birth defects. Another presentation compared Lemtrada to Genentech’s Ocrevus using a model that evaluated both the cost and effectiveness of the two drugs. The analysis suggests that Lemtrada more effectively treated relapsing MS and was also linked to lower costs over a 20-year period. Aubagio studies also focused on long-term patient data, including in people with progressive forms of relapsing MS. Data from the Phase 3 TEMSO , TOWER , and the TEMSO extension showed that Aubagio stabilized disability progression in these patients over nearly a decade. Other presentations homed in on Aubagio’s ability to slow brain tissue loss and improve cognitive outcomes. Finally, Sanofi Genzyme shared initial data on its investigational antibody GLD52. The treatment is an updated form of Lemtrada, which scientists believe gives rise to fewer and milder infusion-related reactions. Data from the Phase 1 study , so far indicated that this might indeed be the case, as no severe reactions occurred in the 44 progressive MS patients in the trial.

MS drug manufacturers are in the sights of two members of Congress The companies are Bayer, Biogen, EMD Serono, Novartis, Sanofi Genzyme, Teva, and Roche. U.S. Reps. Elijah Cummings and Peter Welch, two Democrats who sit on the House Committee on Oversight and Government Reform, are concerned about what they're calling dramatic price increases for some MS drugs produced by those companies. In a news release, the congressmen say the price hikes have come "without warning, cause, or justification." They've sent letters to the companies seeking information about their profits and expenses. The letters also ask for documents about pricing strategies, patient assistance programs, and drug distribution systems. Cummings and Welch point to an American Academy of Neurology study of drug prices as evidence that some pharmaceutical companies appear to be increasing the prices of their older, less expensive drugs to bring those prices in line with those of the newer, more expensive DMTs that are available today. This kind of practice is known as “shadow pricing.” The congressmen refer to this study as being a bit dated, as it was published in May of 2015. It reviews the published prices of nine DMTs over a 20-year period, ending in 2013, and shows that prices for those older, first-generation DMTs increased at an annual rate that was five to seven times higher than general prescription drug inflation. In their news release, the lawmakers also referred to a report from the National Multiple Sclerosis Society that included a chart of drug price increases since the approval date for each drug.

Biogen is a big pharmaceutical company that produces a half-dozen MS drugs. Among them are Tysabri, Avonex and Tecfidera. And Biogen is doing all it can to protect its turf, particularly when it comes to its best seller, Tecfidera. Last month the company filed lawsuits against several…
