#ACTRIMS2018 – Relapsing MS Patients With Impaired Vision Improved on Ocrevus, Updated Trial Data Show

Ocrevus improved vision among relapsing multiple sclerosis patients who participated in the Phase 3 clinical trials of the treatment, according to updated analyses recently presented at the ACTRIMS Forum 2018. While Ocrevus-treated patients improved their ability to read low-contrast letters over the course of the two trials, people who received Rebif (interferon beta-1a) did not. Laura J. Balcer, a neurologist at New York University Langone Medical Center, shared the data in a presentation titled, “Effect of Ocrelizumab on Visual Outcomes in Patients with Baseline Visual Impairment in the OPERA Studies in Relapsing Multiple Sclerosis.” Balcer had earlier shared data on the visual outcomes of relapsing patients in the OPERA I and OPERA II Phase 3 clinical trials of Ocrevus at the 7th Joint ECTRIMS-ACTRIMS Meeting in Paris, last year. The two studies — sponsored by Ocrevus developer Genentech, a member of the Roche group —  compared Ocrevus and Rebif in patients with relapsing MS. This time, her presentation focused only on patients who had visual impairment when they enrolled in the trials. Among a total of 1,656 participants, 375 of those treated with Ocrevus and 373 in the Rebif group had visual impairment. Researchers tested vision using a low-contrast letter acuity test. The test is similar to an ordinary vision test, with letters of different sizes on a chart. But the low-contrast test uses gray letters — instead of black — on a white background. Researchers included charts with two shades of gray to test different contrast levels. These tests can detect reduced visual function. At the beginning of the trials, both groups performed in a similar manner — correctly identifying about 35 letters on a chart with somewhat higher contrast. After 96 weeks, those receiving Ocrevus identified on average 3.4 more letters, while Rebif-treated patients worsened by 0.5 letters — a significant difference, Balcer said. Researchers tested vision every 12 weeks. At the end of the trials, they found that 39 percent more patients in the Ocrevus groups had a cumulative improvement of at least 10 letters, compared to those treated with Rebif. At this time, 26.4 percent of Ocrevus-treated patients improved 10 letters or more, compared to 19.8 percent in the Rebif group. The difference between the groups for at least seven letters was 54 percent, with Ocrevus-treated patients performing better. Researchers believe that a seven-letter change is the minimal clinically important difference for the test. Based on the results, researchers believe that the findings demonstrate Ocrevus’ ability to reverse visual impairment in relapsing MS. The ACTRIMS Forum 2018 is being held in San Diego, California, Feb. 1–3.

European Commission Approves Ocrevus to Treat RRMS, PPMS Throughout EU

The European Commission has approved Roche’s Ocrevus (ocrelizumab) for both relapsing-remitting multiple sclerosis (RRMS) and primary-progressive multiple sclerosis (PPMS) across the 28-member European Union. The commission’s move —  nearly 10 months after the U.S. Food and Drug Administration (FDA) approved Ocrevus in March 2017 — makes it the first approved PPMS…

European Neurologists Ready to Use Both Mavenclad and Ocrevus, Survey Shows

Mavenclad has become the multiple sclerosis therapy of choice for one in five neurologists in Germany and the United Kingdom, according to a Spherix Global Insights survey. Meanwhile, many European neurologists are looking forward to the continent's approval of Ocrevus, particularly as a treatment for primary progressive multiple sclerosis, or PPMS. The United States approved the therapy in March of 2017. European neurologists are using Mavenclad for both relapsing-remitting multiple sclerosis, or RRMS, and secondary progressive multiple sclerosis, SPMS. The report that Spherix issued on European neurologists' treatment choices is called "RealTime Dynamix: Multiple Sclerosis EU." It was based on a survey of 261 neurologists, who were asked about thei disease-modifying drugs they prescribed and the way they manage MS, according to a press release. The survey focused on Merck KGaA’s Mavenclad, which the European Union approved in August 2017, and Genentech’s Ocrevus, which the European Commission is expected to approve soon. The European Medicines Agency paved the way for approval by recommending its authorization earlier this month. Mavenclad is the first disease-modifying therapy that most of the patients who are on it have tried, according to the survey. Spherix analysts said this indicates that Mavenclad may expand the proportion of MS patients using disease-modifying drugs. But while Mavenclad’s label allows patients to use it as a first-line therapy, the survey revealed that many neurologists are not comfortable prescribing it as an initial treatment. This suggests that the Mavenclad-treated population may later include more patients who switched treatments, Spherix said. Mavenclad reduces MS relapses by resetting the immune system, studies have shown. Neurologists who prescribe it as a first-line treatment appear to endorse the idea of induction therapy. This approach involves more potent therapies being used from the onset of the disease. British neurologists in particular appear to favor the induction approach, the report revealed. Patients who had been on previous treatments have switched mainly from Copaxone (glatiramer acetate), interferons, or Novartis' Gilenya, the report showed. Many neurologists' lack of familiarity with Mavenclad may be limiting its use, the report said. It noted that two out of five neurologists had not received a detailed briefing on the drug, and more than one-third had not attended any launch activities. Limited market access was the second most common obstacle to Mavenclad prescription, the report indicated. Interestingly, those who had participated in Mavenclad launch activities said these consisted mostly of independent research or discussions with colleagues, rather than activities organized by Mavenclad’s developer Merck KGaA. Spherix’s survey was done just before the European Medicines Agency recommended Ocrevus' approval in mid-November. Even before the endorsement, the survey indicated, Ocrevus was by far the MS drug in development that most neurologists looked forward to using. The reasons, the neurologists said, were its beneficial effectiveness-safety profile, its new mechanism of action, the fact that it only needs to be given once every six months, and a treatment label that includes PPMS. It is the first disease-modifying drug ever approved for PPMS patients. Twice as many neurologists said they look forward to using Ocrevus as a first-line treatment for PPMS as those saying they wanted to use it as a first-line treatment for relapsing MS. And neurologists estimated that twice as many PPMS patients as RRMS patients are appropriate candidates for Ocrevus treatment. In a report in October about U.S. neurologists' treatment preferences, Spherix said those doctors estimated the number of PPMS Ocrevus candidates at three times that of RRMS patients. Nonetheless, about equally as many PPMS and RRMS patients had tried Ocrevus four months after its launch, the survey showed. The European situation may evolve in a similar manner, since the European Medicines Agency recommended a specific use of Ocrevus in PPMS patients. It specified that the drug be used in PPMS patients who show “imaging features characteristic of inflammatory activity." This makes it likely that only a subgroup of PPMS patients will receive the treatment. The use of Biogen's Tysabri, Gilenya, and Rituxan (rituximab), also made by Roche's Genentech subdivision, will be most impacted by Ocrevus' introduction. Despite this, neurologists believe rituximab's use will grow in the next six months, because Ocrevus is still not available, while lower-cost rituximab biosimilars are.

#MSParis2017 – Genentech to Share Host of New Ocrevus Data at ECTRIMS-ACTRIMS Meeting

Genentech will present a host of new information on its multiple sclerosis treatment Ocrevus and lessons its scientists have learned about the disease at the 7th Joint ECTRIMS-ACTRIMS Meeting in Paris, Oct. 25–28. The presentations will offer new insights into the therapy's mechanisms, safety and effectiveness in people with the primary progressive and relapsing forms of MS. They will also look at new ways to track MS, including additional biomarker possibilities. MS experts say the joint meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) and Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) is one of the largest global congregations of scientists working on the disease. The information Genentech plans to present will demonstrate "the commitment of our scientists and research partners to advance understanding of MS progression through ongoing analyses of the Ocrevus Phase 3 clinical trials,” Dr. Sandra Horning, the company's chief medical officer and head of its Global Product Development arm, said in a press release. Genentech, which is part of the Roche group, said the 18 presentations will represent the largest body of evidence ever presented on Ocrevus. The discussions will reinforce the therapy's favorable benefit-risk profile, Genentech added. Two presentations will cover new ways that doctors can look for signs of disease activity that can lead to disability. One yardstick is called progression independent of relapse activity, or PIRA. Another is tracking slowly evolving lesions. Genentech researchers came up with the approaches when they analyzed a subgroup of patients in the OPERA I and OPERA II Phase 3 clincal trials, whose aim was to evaluate Ocrevus as a treatment for relapsing MS. The patients' disease progressed even though they had no relapses, researchers said. The team will also discuss how Ocrevus affected these patients' disease. Another presentation will cover long-term follow-up data from an extension of the ORATORIO Phase 3 clinical trial (NCT01194570), which dealt with Ocrevus' ability to treat primary progressive MS. It will   look at how well Ocrevus slowed the progression of patients' disability. Updated information on Ocrevus’ safety —  based on open-label extension studies — will be another component of the presentations. So far, researchers have detected no new safety issues. Genentech will also discuss a new way of using conventional magnetic resonance imaging (MRI) to identify and track slowly evolving lesions. The company's scientists think that tracking the lesions may be a good way to measure chronic disease activity. This would contrast with tracking ordinary MS lesions, which are biomarkers of acute — as opposed to chronic — disease activity. In addition to "two new potential markers of underlying disease activity and their impact on disease progression, we hope to bring new tools to the MS community to better understand and manage the disease,” Horning said. One tool, which Genentech has begun testing in clinical trials, is gathering patient information with sensors connected to a smartphone. Researchers are comparing the information obtained in the FLOODLIGHT study with what physicians record during patient visits. The research team believes the FLOODLIGHT method may be be able to detect subtle changes better. This could make it a better predictor of disease activity and long-term patient outcomes. In addition to the presentations, Genentech will sponsor two symposia at the meeting that will discuss how MS progresses, features of the chronic version of the disease, and the link between inflammation and the progression of MS. The U.S. Food and Drug Administration approved Ocrevus in March 2017.  

Switzerland First in Europe to Approve Ocrevus for Relapsing and Primary Progressive MS

Swiss regulatory authorities approved Ocrevus as a treatment for primary progressive and relapsing forms of multiple sclerosis on Sept. 28, making it the first approval of the drug in a European country. Since Switzerland is not part of the European Union, the approval will not affect the drug's regulatory status in other European countries. So far, the Roche/Genentech drug Ocrevus has been approved in North America, South America, the Middle East, Ukraine, and Australia. Like other countries where Ocrevus has been approved, it's the first drug OK'd in Switzerland for primary progressive MS, a form of the disease where disability moves forward relentlessly. And, as in other countries, the treatment option is equally appreciated among patients with relapsing types of MS. Ocrevus — an antibody that targets B-cells with the surface factor CD20 — was studied in two large Phase 3 trials in patients with relapsing MS called OPERA I and OPERA II (NCT01247324 and NCT01412333). Another trial, called ORATORIO (NCT01194570), is focused on people with primary progressive disease. The trials showed that the treatment significantly reduced disease activity and prevented progression in both patient groups. Researchers compared Ocrevus to Rebif (high-dose interferon beta-1a) in relapsing MS and to a placebo in primary progressive MS. Scientists also consider the drug to have a good safety profile. The most common side effects during the trials were mild-to-moderate infusion reactions and upper respiratory tract infections. Since its approval, researchers also have concluded that the treatment is less expensive than interferon. Ocrevus was approved in the U.S. on March 28, 2017. In the months that followed, many patients were concerned about the trial findings of more cancer cases in the treated, compared to control, groups. Since then, an increased risk of cancer with Ocrevus has not been confirmed, and researchers underscore that it is instead the coincidental and unusual circumstance that there were no cancer cases in the control group that created the imbalance. The European Medicines Agency is still processing the marketing application for Ocrevus. Roche reports that the company has filed marketing applications in more than 50 countries worldwide.

Ocrevus Approved in Canada to Treat Relapsing-Remitting MS

Health Canada has approved Ocrevus for the treatment of adults with relapsing-remitting multiple sclerosis (RRMS) with active disease, Roche Canada announced. The approval followed the positive results from the Phase 3 OPERA studies, which evaluated the safety and efficacy of Ocrevus in 825 patients with RRMS. The OPERA 1 and OPERA 2 trials showed that Ocrevus significantly reduced disease activity and disability progression of RRMS patients, with annual relapse rates falling by almost half. Moreover, Ocrevus outperformed Rebif, the standard of care in MS, in slowing worsening of disability and significantly reducing lesions seen on MRI scans over a two-year treatment period. "Ocrevus is a major addition to the treatment options available for MS. The RRMS Ocrevus clinical trial data show a significant reduction in relapses and disease progression, as well as a good safety profile," Daniel Selchen, a neurologist and head of the Division of Neurology at St. Michael's Hospital in Toronto, said in a press release. "For appropriate patients, Ocrevus will be of great value in reducing the burden of MS." The treatment's approval, however, did not extend to — or mention — people with primary progressive MS, in contrast to the U.S. Food and Drug Administration's action in March, which approved Ocrevus for both MS forms. Health Canada did not give address PPMS in its announcement. Estimates are that 100,000 Canadians are currently living with MS, and most have the relapsing form. A number welcomed Ocrevus' arrival for what it offers in their fight against this disease.
