#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.

#ACTRIMS2018 – Oryzon Enrolls First Patient in SATEEN Trial, Presents New Data at MS Meet

Oryzon Genomics has enrolled the first multiple sclerosis patient in its Phase 2a SATEEN clinical trial investigating the therapy ORY-2001. The Spanish company will also present new results from preclinical models of MS treated with ORY-2001 at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2018, set for Feb. 1-3 in San Diego. ORY-2001 is an epigenetic therapy, meaning it targets the expression and activity of genes. The drug inhibits two particular molecules, LSD1 and MAOB, and was previously shown to reduce cognitive impairment and neuroinflammation in preclinical models, including in a mouse model of MS — the experimental autoimmune encephalomyelitis (EAE) model. The therapy was also shown to have neuroprotective effects. During ACTRESS 2018, Oryzon's chief scientific officer, Tamara Maes, will present a poster, "ORY-2001 reduces inflammatory cell infiltration in the Theiler’s murine encephalomyelitis virus model and highlights the epigenetic axis in MS.” “In previous reports we showed that ORY-2001 reduces the clinical score, lymphocyte egress, immune cell infiltration and inflammation protecting the spinal cord from demyelination in a murine MS-EAE model,” Maes said in a press release. “Here we provide data on the efficacy of ORY-2001 in the Theiler’s murine encephalomyelitis virus model for multiple sclerosis." In a second poster, "ORY-2001 in multiple sclerosis: first clinical trial of a dual LSD-1/MAOB inhibitor,” Roger Bullock, Oryzon's chief medical officer, will detail the Phase 2a trial, SATEEN, testing ORY-2001 in patients with relapsing-remitting or secondary progressive MS over a 36-week period, followed by an open-label extension. “Our first patient enrolled in SATEEN signals a new landmark for the clinical development of this drug in different neurological indications,” said Bullock. “This is the first epigenetic approach in this disease, and we hope that it will contribute to enlarge and improve the therapeutic options for patients afflicted by MS."

Easing Blood Flow in Neck Reduces Headaches, Fatigue in Certain MS Patients, Study Shows

Removing obstructions in large neck veins reduced multiple sclerosis patients’ headaches for several years, British and Italian researchers have demonstrated. The magnitude and duration of the effect differed among patients with different types of MS, however. Researchers also found that the treatment reduced fatigue, particularly in relapsing-remitting (RR) MS patients.

MS Patients’ High Osteopontin Protein Levels Make It a Potential Biomarker for the Disorder, Study Reports

Multiple sclerosis patients have high levels of a protein called osteopontin in their cerebrospinal fluid and blood, making it a potential tool for diagnosing the disease and predicting its course, a study suggests. The research, “Osteopontin (OPN) as a CSF and blood biomarker for multiple sclerosis: A systematic review and meta-analysis,” was published in the journal PLOS One. Researchers wanted to know if levels of osteopontin in cerebrospinal fluid and blood could be a reliable biomarker for MS. To arrive at answer, they “conducted a systematic review and meta-analysis" of studies that had measured the protein's levels in cerebrospinal fluid and blood "in MS patients and controls." The team searched for studies in three databases — PubMed, Web of Science and Scopus. Out of 27 that met their criteria, they used 22 in the meta-analysis. All four types of MS were represented in the studies — clinically isolated syndrome, relapsing-remitting MS, secondary progressive MS, and primary progressive MS. There were three types of controls in the articles — healthy people, people with non-inflammatory neurological disorders, and people with inflammatory neurological disorders. Researchers' first observation was that all of the MS patients had higher levels of osteopontin than controls. The protein's levels were significantly higher in relapsing-remitting MS patients than in those with clinically isolated syndrome, the group with the lowest osteopontin levels. Levels were similar in the other types of MS. Patients with an active disease had significantly higher levels of the protein in their cerebrospinal fluid than those with a stable disease. The results supported previous studies' findings that osteopontin levels are higher than normal in the cerebrospinal fluid and blood of MS patients, strengthening the notion that it could be used as a biomarker for MS. “Given the fact that OPN [osteopontin] levels are higher during relapses, we think that by monitoring this biomarker,  we might be able to predict the disease course," the team wrote. "We propose that developing drugs modulating OPN concentration may be a new treatment strategy for MS."

Study Identifies MS Patients at Risk of Severe Disease Reactivation After Gilenya Is Discontinued

Multiple sclerosis patients with high relapse rates but less physical impairment before starting on  Novartis’ Gilenya (fingolimod) are likely to experience a surge in disease activity if they stop the treatment, researchers in Turkey report. The study, which dealt with patients with relapsing forms of MS, referred to the surge as "severe disease reactivation," or SDR. Researchers published their article, “Factors Predictive of Severe Multiple Sclerosis Disease Reactivation After Fingolimod Cessation,” in the journal The Neurologist. Studies have shown that Gilenya, which the U.S. Food and Drug Administration approved in 2010, can benefit adults with relapsing MS. It reduces annualized relapse rates and prevents more brain lesions from forming, compared with standard interferon treatments. Lesions are damaged nerve cell areas. Despite its benefits, Gilenya is not recommended for patients with heart or liver problems, low levels of white blood cells, severe herpes virus infections or other infections. Also, patients who do not respond to Gilenya and women who are planning to become pregnant are advised to stop the treatment. Discontinuing Gilenya can lead to a return to pretreatment disease activity, or severe disease reactivation, in some patients. It is unclear why this happens and why it affects only some patients. To better understand what risk factors could be associated with reactivation, a team at Istanbul University compared the demographic and disease features of patients who developed SDR after stopping treatment with Gilenya. SDR was defined as including these elements within 6 months of Gilenya discontinuation: more than 5 gadolinium-enhanced lesions or a tumefactive demyelinating lesion detectable by magnetic resonance imaging, the disease progressing to the point that additional treatment with methylprednisolone or plasma exchange was required, and progressive physical disability reflected by a 1-point or more increase in patients' scores on the Expanded Disability Status Scale, or EDSS, Thirty-one patients at the university’s MS clinic who had discontinued Gilenya were included in the study. Eight experienced SDR and 11 relapses. The mean time for SDR patients' reactivation to occur was 2.6 months, researchers said. Patients had significantly higher levels of lymphocytes — white blood cells involved in autoimmunity — than during Gilenya treatment. When the team compared the disease features of SDR and non-SDR patients, they found that SDR patients had significantly higher annualized relapse rates before starting Gilenya and lower EDSS scores. “A higher ARR [annualized relapse rate] is the major contributory factor toward development of SDR,” the researchers wrote. “Patients who had higher ARRs before fingolimod [Gilenya] treatment must be closely followed up both clinically and radiologically in terms of the early signs of severe reactivation,” they wrote. About 38 percent of the SDR patients failed to respond to steroid treatment. They received a plasma exchange, which led to moderate improvement in their condition. Based on this finding, the researchers suggested that “plasmapheresis [plasma exchange] must be considered in patients exhibiting steroid-refractory SDR.” "In conclusion, SDR may be observed within the first 3 months after cessation of fingolimod," the team wrote. "This may be explained by the rapid influx of lymphocytes into the CNS [central nervous system]. Patients with higher annualized relapse rates and lower Expanded Disability Status Scale scores before commencing fingolimod treatment were more likely to exhibit SDR."
