Resistance training like weight lifting can protect or even regenerate the nerve cells of relapsing-remitting multiple sclerosis patients, slowing the progression of the disease, according to a clinical trial. A hallmark of MS is the brain shrinking faster than normal, and findings from this trial indicates that resistance training can slow the shrinking or even make some brain areas grow. Research has shown that physical training benefits MS patients, helping them alleviate many symptoms, including excessive fatigue and balance control problems. Recent studies suggest that exercise can have a disease-modifying role in MS. This means physical activity can be an important adjuvant, or add-on therapy, for standard-of-care regimens. Researchers followed 35 patients with relapsing-remitting MS for 24 weeks. Eighteen patients did resistance training twice a week, consisting of four lower- and two upper-body exercises. The other 17 patients struck with their normal routines. Before and after the 24 weeks, doctors took magnetic resonance imaging scans, or MRIs, to evaluate patients' brain structures. After the 24 weeks, the scans showed less brain shrinkage in those who had resistance training. Some of their cortical brain regions were also thicker — an indication they were growing. It is not clear why exercise benefits MS patients' brains, nor if exercise has the same effect on all patients. Additional studies are needed to clarify its therapeutic effect, the researchers said. That knowledge could help improve current MS therapies.

Ocrevus' market introduction is off to a stellar start, with nearly half of neurologists surveyed by Spherix Global Insights saying they are using the therapy — the first ever approved for both relapsing and primary progressive multiple sclerosis. Within six months, 80 percent of neurologists are expected to prescribe Ocrevus, according to a report in the second-quarter edition of RealTime Dynamix: Multiple Sclerosis by Spherix Global Insights. But insurance is having an increasing impact on treatment decisions, the report also found, according to a Spherix press release. More patients are receiving less than optimal care because of inadequate or inferior insurance coverage, and neurologists report that insurers have become more aggressive in managing MS patients. Surveying 104 neurologists in June, the report showed that physicians followed through with their intent — reported in earlier surveys — to prescribe Ocrevus as it became available. With Ocrevus being the first approved drug for primary progressive MS, these patients make up a sizable part of those receiving it. But patients with relapsing forms of MS represent more than half of new users, according to the report. Ocrevus was also, by far, the drug that neurologists had learned most about, and felt most excited about using, the report added. Most of the patients on Ocrevus were switched from Biogen's Tysabri or Rituxan — a drug that, like Ocrevus, is also produced by Genentech/Roche. One in five patients was switched from an oral disease-modifying treatment, mainly Biogen’s Tecfidera (dimethyl fumarate). But for about 25 percent of Ocrevus-treated patients, the drug is the first disease-modifying therapy they have received. The survey also revealed that patients are the driving force behind new Ocrevus prescriptions. Seventy-one percent of neurologists receive requests from patients who want to start the treatment. While neurologists have to turn some of these requests down for various reasons, a large proportion of those who ask for the treatment receive it. Another insight from Spherix’s “RealWorld Dynamix: DMT Brand Switching in MS” survey was that patients' requests for a specific brand are often honored. Seventy-seven percent were prescribed the brand they requested, the survey showed. Interestingly, neurologists believed the number to be lower. Most patients who made a specific request, the report indicated, asked for Tecfidera in the past year and a half. Tecfidera is by far the leading oral disease-modifying drug prescribed in MS. Meanwhile, according to the report, Biogen's Avonex, Bayer's Betaseron, Teva's Copaxone, and EMD Serono's Rebif continue on a downward path. At least 30 percent of neurologists report lower use of these therapies in the past three months. Patients previously on these drugs are mainly switched to oral disease-modifying drugs. But this trend is projected to slow, with only Sanofi-Genzyme's oral Aubagio (teriflunomide) continuing to grow. But the choice of treatment may increasingly be driven by insurance. Compared with the same quarter of 2016 — when neurologists estimated that 14 percent of patients received suboptimal treatment because of poor insurance coverage — 20 percent of patients are now judged to be in this situation. Also, 60 percent of surveyed physicians feel that insurance companies have become more aggressive in MS treatment management. A similar percentage also say that insurance policies influence how they prescribe specific disease-modifying drugs.
Australia has become the first country to approve Genentech's Ocrevus for relapsing and primary progressive multiple sclerosis treatment since the therapy's initial approval by the U.S. Food and Drug Administration in March 2017. The Australian Therapeutic Goods Administration gave Ocrevus the green light on July 17, filling an unmet need for Australia's estimated 23,000 MS patients. “We are pleased that another regulatory body recognized for its rigorous review process has approved Ocrevus with a broad label as a new treatment option for people with relapsing or primary progressive MS in Australia,” Dr. Sandra Horning, Roche’s chief medical officer and head of global product cevelopment, said in a press release. “Approval in Australia is significant because of the high prevalence of MS in the country, making it the leading cause of non-traumatic disability in young adults." The drug's developer, Genentech, and Genentech's parent company Roche have submitted applications to get Ocrevus approved in more than 50 countries in Europe, Latin America and the Middle East. Ocrevus trials showed that, among relapsing patients, relapse rates were nearly halved compared to those treated with Rebif. Many of these patients also reached a level of no disease activity — measures that Genentech has continued to explore after the drug's U.S. approval. In addition, data also showed that PPMS patients, who deteriorate more rapidly, benefit from Ocrevus treatment. “People with PPMS [primary progressive multiple sclerosis], who often experience faster and more severe disability, have not had any approved treatment until Ocrevus," Horning said. "We continue to work closely with regulatory authorities across the world to bring Ocrevus to people with multiple sclerosis as soon as possible." Ocrevus is an antibody that blocks the CD20 molecule on certain immune B-cells. Researchers believe these cells directly damage myelin — the protective coat that insulates nerve cells in the brain and spinal cord. Evidence also indicates that B-cells can directly damage neurons themselves. The drug continues to be evaluated in a range of clinical trials, including one that specifically focuses on how the drug’s B-cell depleting actions play out to harness MS disease processes.
Copaxone Benefits RRMS Patients in the Long Term by Modulating Immune System Responses, Study Shows
First-line treatment with Copaxone (glatiramer acetate) benefits relapsing-remitting multiple sclerosis (RRMS) patients by boosting the number of anti-inflammatory immune cells and restoring the balance of regulatory immune cells, an Italian study shows.

Dormant Herpes Virus Can Impede Repair of Myelin Sheath Whose Deterioration Causes MS, Study Reports
A herpes virus that lies dormant in many people can hinder the repair of the neuron-protecting myelin sheath whose deterioration causes multiple sclerosis, a study reports. The finding about the HHV-6 virus may help explain differences in the symptoms and progression of the disease from person to person, researchers said.
Allergy Medicine Fails to Reduce Flu-Like Syndrome in Relapsing-remitting MS Patients, Study Shows
According to a new clinical trial, the allergy treatment cetirizine fails to alleviate a flu-like condition that interferon-beta treatment generates in people with relapsing-remitting multiple sclerosis. The results, which surprised researchers, apply to flu-like syndrome, or FLS. Cetirizine is an over-the-counter medicine sold under the brand names Zirtec, Zyrtec, Reactine, and Triz. FLS affects roughly 75 percent of patients who take interferon-beta, also known as IFN-beta. It can cause fever, chills, muscle pain, weakness, and headache. The symptoms commonly occur three to six hours after an IFN-beta injection and last up to 24 hours. Although FLS usually subsides in the first three months of IFN-beta therapy, it persists in some patients, causing them to miss doses or even discontinue the treatment. Cetirizine is an antihistamine for hay fever and allergies. The purpose of the clinical trial was to determine whether cetirizine could alleviate RRMS patients' FLS. In order to determine study results, patients did self-assessments of how much discomfort their FLS caused them. There were no significant changes in the two groups' average self-assessment scores at four and eights weeks of treatment, suggesting that cetirizine does not offer significant benefits to RRMS patients with FLS. “The addition of a [cetirizine] to the standard of care for IFNβ-induced FLS in patients with RRMS does not seem to improve symptoms significantly compared with placebo," the team wrote. "FLS continues to be inadequately treated in many RRMS patients. Further investigations are needed to elucidate the underlying mechanisms of IFNβ-induced FLS and develop adequate strategies for prevention and treatment."
B-cells of patients with relapsing-remitting multiple sclerosis (RRMS) secrete substances that are toxic to both neurons and neuron-protecting myelin-forming cells, causing both kinds to die, according to a study. Despite analyses of numerous inflammatory and other factors believed to drive MS processes, researchers were unable to identify the molecules that are toxic, however. Dr. Robert Lisak of Wayne State University in Detroit, Dr. Amit Bar-Or of McGill University in Montreal and their teams are now working on identifying the factor, and learning if the process is also involved in progressive MS. Their study, “B-cells from patients with multiple sclerosis induce cell death via apoptosis in neurons in vitro,” was published in the Journal of Neuroimmunology. It demonstrated that B-cells gathered from the blood of RRMS patients killed lab-grown neurons and oligodendrocyte cells, which form myelin, a protecting coating for nerve cells. Deterioration of the myelin coating and the death of neurons are hallmarks of MS. An earlier study the team conducted indicated that B-cells from MS patients could kill oligodendrocytes. But since the experiments involved only three patients and three controls, the team scaled up their experiments to include 13 patients and an equal number of controls. Both rat and human neurons died when mixed with MS-derived B-cells. In contrast, B-cells from healthy people had little or no impact on the survival of the brain cells. Researchers also discovered that the secreted toxic molecules had no impact on other types of central nervous system cells — astrocytes and microglia. The toxins killed only neurons and myelin-producing cells. The B-cells triggered a process called apoptosis, or programmed cell death, researchers said. This is basically a suicide program. It tells a cell to die when exposed to stressful factors or toxins. The process differs from cell disintegration. Despite thoroughly screening about 40 inflammation-related substances, researchers were unable to identify any factors that caused the cells to die. The National MS Society and the Research Foundation of the MS Society of Canada funded the research, which the U.S. society highlighted in a news release. In the newest phase of the study, researchers will try to learn more about the processes underlying neuron and myelin-related cell deaths and identify the factors responsible. In addition to testing B-cells from progressive MS patients, the team will examine patients with other autoimmune conditions to see if the process is unique to MS or not. Researchers increasingly realize that B-cells are important to MS processes. This observation was underscored by U.S. regulators' approval of the B-cell depleting therapy Ocrevus (ocrelizumab) at treatment for both relapsing and primary progressive MS.
Genentech shared new insights into the workings of Ocrevus (ocrelizumab) and its effectiveness in reducing disease activity and slowing progression in relapsing and primary progressive multiple sclerosis (MS) at the recent 3rd Congress of the European Academy of Neurology (EAN). The new findings, previously reported here, built on analyses of information gathered during the three Phase 3 clinical trials assessing Ocrevus' safety and efficacy, as well as through monitoring patients in extension studies. The studies showed that nearly 40 percent of Ocrevus-treated relapsing patients and nearly 30 percent of primary progressive patients achieved NEPAD during the Phase 3 trials. In contrast, only 21.5 percent of those treated with Rebif and 9.4 percent receiving placebo achieved NEPAD — figures that demonstrate Ocrevus’ impact on patients’ lives, as well as Ocrevus’ ability to slow the decline in walking ability and other types of disabilities are comparable between patients with relapsing and primary progressive disease — data that demonstrate that the treatment acts on disease mechanisms that drive disability in both disease forms. How these effects play out in the long-term is the subject of ongoing research, as Genentech continues to follow these patients in an extension study. In addition, Ocrevus' prescription label strongly advises against pregnancy while on the treatment. Despite precautions, some women became pregnant during the trials. One of the meeting presentations narrated outcomes of these pregnancies; one healthy baby born at term and two ongoing pregnancies in women exposed to the drug. But while Genentech monitors women who become pregnant while on Ocrevus, the number of reported pregnancies is too small to draw conclusions about the treatment’s safety in pregnancy, and researchers do not know if Ocrevus also depletes B-cells in the fetus or in the baby born to a treated woman.
Problems with sense of smell are more frequent and severe in patients with primary progressive multiple sclerosis (PPMS) than in those with relapsing-remitting multiple sclerosis (RRMS), a study reports. The research, “Olfactory dysfunction in patients with primary progressive MS,” was published in the journal Neurology: Neuroimmunology and Neuroinflammation. A distinguishing feature of RRMS, the most common form of the disease, is attacks of new or increasing neurologic symptoms, such as movement disorders, and then recovery periods. About 15 percent of patients have the primary progressive form, or PPMS. Its main feature is gradually increasing neurologic disability without recovery periods. Some scientists believe PPMS is a less inflammatory course of MS. The differences in the processes that underlie each form are not well understood, however. Several researchers think that studying differences in the two groups' ability to smell — or olfactory dysfunction — could shed light on these underlying processes. Autopsies of MS patients in one study showed that 71 percent had experienced demyelination, or loss of neurons, in the brain's olfactory pathway. The processes that led to this dysfunction were unclear, however. Researchers decided to test the hypothesis that olfactory impairment is more pronounced in patients with PPMS than RRMS. The team examined 32 patients with PPMS, 32 with RRMS, and 32 healthy controls. The yardstick they used to evaluate sense of smell was the olfactory Threshold Discrimination Identification (TDI) Test. It involves patients smelling 48 sniffin' sticks. In addition to an overall TDI, there were subscores on olfactory threshold, odor identification and odor discrimination. Olfactory threshold refers to the lowest concentration of an odor that a person can detect. Researchers found olfactory dysfunction in 27, or 84 percent, of the PPMS patients; 10, or 31 percent, of the RRMS patients; and 1, or 3 percent, of the healthy controls. The TDI score and all subscores were significantly worse in patients with PPMS than in the controls, when considering patients of similar age and the same sex. The TDI score was also worse in PPMS patients than in the RRMS group, after adjusting for age, sex, MS disability level, the length of time patients had the disease, and patients' ability to identify and discriminate among odors. Researchers acknowledged limitations to the study. One was the small size of the groups in the research. Another was not using magnetic resonance imaging, or MRI, to measure olfactory pathway deterioration. Comparing the brain's olfactory pathway region with other brain regions in both the RRMS and PPMS groups could have shed light on the processes underlying the olfactory dysfunction differences between the two, researchers said. “The findings suggest that olfactory dysfunction might be a surrogate of neurodegeneration in these patients," the researchers wrote. "Studies correlating olfactory function with radiologic and clinical markers of disease progression would be of interest.”
