Mallinckrodt Pharmaceuticals is seeking 66 participants for a clinical trial to determine the safety and effectiveness of its injected therapy H.P. Acthar Gel as a treatment for acute relapses in people with relapsing-remitting multiple sclerosis (RRMS). MS relapses are flare-ups of central nervous system inflammation that damage the myelin coating that protects nerve cells. The damage disrupts the transmission of impulses between the cells, causing spikes in MS symptoms. For severe relapses that interfere with a person’s mobility, safety or ability to function, most neurologists recommend corticosteroid treatment administered intravenously or taken orally. Steroids can also be administered by injection of a gel under the skin. H.P. Acthar Gel is designed to provide extended release of steroids in the body. The trial will evaluate whether the gel is an effective treatment for RRMS patients who have been unable to recover from a relapse after receiving high-dose intravenous or oral steroids. Researchers will randomly assign participants to receive either H.P. Acthar Gel or a placebo, delivered by injection once a day for 14 days. Follow-up visits will be required at 14, 28 and 42 days. The study's main objective will be seeing whether patients' disability improves. Researchers will use a standard tool for measuring disability known as the Expanded Disability Status Scale.  Other objectives will include seeing how the therapy affects patients' fatigue, quality of life, workplace productivity, and use of healthcare resources. Participants must have a confirmed diagnosis of RRMS, be older than 18 years of age, and have experienced a relapse within 29 days of enrolling in the trial. For more information about enrollment criteria and how to participate in the trial, please contact Valerie Carvajal at (800) 556-3314 or by email at [email protected]. The National Multiple Sclerosis Society announced in an MS trial alert that Mallinckrodt will be  enrolling participants in Tucson; Fort Collins, Colo.; Tampa; Atlanta; Savannah, Ga.; Northbrook, Ill.; Fort Wayne, Ind.; Indianapolis; Kansas City, Kan.; New York; Cleveland; Dayton, Ohio; Dallas; Round Rock, Texas; San Antonio; Salt Lake City; Richmond, Va.; and Tacoma, Wash. Without clinical trial participation there is no way for patients to obtain new medicines or for scientists to ultimately find a cure for MS. The National MS Society encourages participation. It has developed a guide for patients who want to take part in studies called “Participating in Clinical Trials.” It covers the basics of participation, benefits versus risks, patient protection, costs and other important issues about trials.

Australia has approved a shorter treatment regimen of Merck’s Mavenclad for relapsing-remitting multiple sclerosis. The Therapeutic Goods Administration authorized 20-day courses of the cladribine tablet form of the medication once a year for two years. The regimen reduces relapse rates and the progression of the disease for up to four years, Merck said. The new approval came after Merck submitted additional clinical trial findings on the therapy. Health Canada and the European Commission approved Mavenclad earlier this year. Merck continues to seek its regulatory approval in the United States and other countries. "Mavenclad will be a welcomed treatment option for patients with the relapsing-remitting form of MS,” Bill Carroll, clinical professor of neurology at the University of Western Australia and the Perron Institute, said in a press release. “As an oral therapy taken in two short courses over a two-year period, Mavenclad will be convenient for all eligible patients in Australia, including those who may not live close to their treating healthcare professional," added Carrol, a neurology consultant at the Sir Charles Gairdner Hospital as well as president-elect of the World Federation of Neurology. Mavenclad targets immune cells that trigger relapsing MS. Multiple sclerosis is an autoimmune disease, or one in which the immune system attacks healthy cells. Mavenclad inhibits harmful immune T- and B-cells without suppressing the entire immune system. Australia based its approval of the drug on the findings of a number of clinical trials, including the Phase 3 CLARITY, CLARITY EXTENSION and ORACLE-MS studies, the Phase 2 trial ONWARD study, and the long-term PREMIERE studies. The trials involved more than 2,700 RRMS patients, some of whom were followed more than 10 years. The trials showed that Mavenclad can significantly reduce relapse rates, disability progression and brain atrophy. Doctors recommended the therapy for patients who failed to respond to, or are unable to tolerate, other MS treatments. "We are pleased the Therapeutic Goods Administration has updated the product Information for Mavenclad in Australia to reflect additional clinical data," said Simon Sturge, chief operating officer of Merck's biopharma business. "Our next step is to work closely with the Australian government to bring this treatment advance to patients as quickly as possible."

Canadians with relapsing-remitting multiple sclerosis can now receive Merck’s Mavenclad, now that Health Canada has approved Mavenclad as a therapy to reduce the frequency of MS exacerbations and delay disease progression. Merck expects the drug to be commercially available by early January 2018 throughout Canada, which has the world's highest MS rate. This follows the drug’s approval by the European Commission in August, making Mavenclad Europe's first approved highly efficient, oral short-course therapy for relapsing MS. Merck said it would seek regulatory approval of Mavenclad in other countries, including the United States. Mavenclad was designed to selectively target immune cells that trigger relapsing MS, while resetting the immune system. With two annual courses of treatment for a maximum of 20 days over two years, the oral drug promotes long-term inhibition of harmful immune T- and B-cells, without continuous suppression of the immune system. Researchers evaluated Mavenclad in five clinical trials: Phase 3 trials CLARITY, CLARITY EXTENSION and ORACLE-MS; the Phase 2 trial ONWARD study ; and the long-term study PREMIERE. These involved more than 2,700 RRMS patients, some of whom were observed for more than 10 years. Clinical data showed that Mavenclad can significantly reduce disability progression, annualized relapse rates and brain atrophy. The treatment is generally recommended for patients who failed to respond adequately, or are unable to tolerate, one or more MS therapies.

Alkermes and Biogen have begun working together on a compound known as ALKS 8700 as a potential treatment for relapsing forms of multiple sclerosis. Under the agreement, Alkermes will be responsible for obtaining regulatory approval of the drug, while Biogen will handle its marketing. ALKS is taken orally. The body quickly transforms it into a compound known as monomethyl fumarate that can counter MS. Aikermes designed it to have better features than Tecfidera (dimethyl fumarate) — in particular, fewer gastrointestinal side effects. The partnership gives Biogen worldwide marketing rights to ALKS 8700. Alkermes will receive a royalty on global sales. Aikermes is evaluating ALKS 8700's safety and effectiveness in what it has dubbed the EVOLVE-MS clinical trial program. It includes two Phase 3 trials that are comparing ALKS 8700 with Tecfidera in patients with relapsing-remitting MS, or RRMS. Preliminary results of the EVOLVE-MS-1 trial, which involved 580 patients, showed few gastrointestinal side effects from ALKS 8700. The most common adverse events in the first month of treatment were flushing, diarrhea, and a rash known as pruritus. Aikermes discussed the treatments safety, and patients' ability to tolerate it, at the 7th Joint ECTRIMS-ACTRIMS Meeting in Paris in October. The company is still recruiting participants for a second trial that will compare ALKS 8700 and Tecfidera's effect on the gastrointestinal system. The EVOLVE-MS-2 study will  be conducted at locations in several U.S. states and six sites in Poland. Alkermes expects to release initial findings from the trial in the first half of 2018.  

In the future, a blood test may make diagnosing multiple sclerosis (MS) much easier, thanks to newly identified biomarker patterns that distinguish between MS patients and healthy people. The test could also correctly detect primary progressive MS (PPMS) in patients who also had relapsing-remitting disease (RRMS). Australian researchers suggest that…

Aerobic exercise strengthens brain connections in people with relapsing-remitting multiple sclerosis, Jan-Patrick Stellmann, with University Medical Center Hamburg-Eppendorf in Germany, reported at the 7th Joint ECTRIMS-ACTRIMS Meeting in Paris that ran from Oct. 25–28. According to Stellmann, "aerobic exercises are considered to improve mobility, fatigue, depression and cognition in MS," and also to "promote neuroprotective or neuroregenerative mechanisms." For the study, the team used MRI to examine how exercise affected different types of brain connections. They recruited 57 RRMS patients and 30 healthy controls to the study. Women made up more than two-thirds of the patient group, which had a mean age of 39. Patients only had mild disability, with a mean score of 1.5 on the Expanded Disability Status Scale. Researchers randomly assigned about half the group to a supervised and individually adapted aerobic exercise program, consisting of 22 sessions of up to one hour each. Others were assigned to a waiting list — with the intent of taking up exercise after three months — and served as a control group. MRI scans at the study's beginning revealed that patients had more so-called functional connections, but fewer structural ones, than healthy controls. It is known from earlier studies that most RRMS patients show abnormalities in functional connections, but some researchers find increases while others decreases in these connections. Functional and structural connections appear on different types of MRI scans — ones that make use either of blood flow changes or of the properties of water molecules in the white matter of the brain. The deviations were particularly pronounced in highly connected hub regions, the researchers said. After three months, functional connections increased across the entire brain among exercising patients, but decreased in those on the waiting list. Structural connections also increased among patients who exercised, while no change was detected among control patients. Researchers also noted that exercising patients grew more local connections, mostly in hub regions, compared to those who did not exercise. While it is generally accepted that aerobic exercise promotes neuroprotective and regenerative processes within the brain, the study demonstrated that exercise, in only three months, did indeed affect how the brain is wired. "Short-term aerobic exercise increases functional and structural connectivity," Stellmann concluded. "Already after three months, exercise lead to functional and structural reorganization of brain networks." The researcher highlighted the difficulties in obtaining financial support for trials on exercise. And he emphasized that patients should be encouraged by their doctors to exercise regularly.

Patients with primary progressive multiple sclerosis have more severe cognitive impairment than those with relapsing-remitting multiple sclerosis, according to a German study that analyzed published data on the topic. PPMS patients did especially poorly on verbal learning and verbal memory tests, said the study, which suggested that PPMS patients need disease management that specifically focuses on their cognitive difficulties, which do not necessarily correlate with the degree of overall disability. The study gathered data from 47 previously published studies in an attempt to analyze potential differences in cognitive performance between patients with RRMS and PPMS. These studies included 4,460 patients — 3,456 with RRMS and 1,004 with PPMS — and plenty of information about patient and disease features. This allowed researchers to perform a meta-analysis of pooled data from various studies, that is considered the highest level of scientific evidence. Researchers noted that PPMS patients performed worse on cognitive tests, both when considering global scores and tests of specific cognitive domains. Yet both groups scored similarly in levels of anxiety, depression and fatigue. Using statistical analyses, the research team found that differences in sex, education, disease duration, manual dexterity and fatigue could not explain the poorer test results among PPMS patients. On the other hand, PPMS patients were, on average, older than those with relapsing disease, and the team found that this difference accounted for poorer test results in cognitive tests of processing speed and working memory. Yet differences in other cognitive aspects also remained when researchers took age into account. Differences in disability, measured by the Expanded Disability Status Scale, could also not explain why PPMS patients performed worse on the cognitive tests. A detailed look revealed that the largest differences between RRMS and PPMS patients were in verbal learning and verbal memory, along with the age-associated difference in processing speed. Depression and anxiety also brought down processing speed, researchers said, even though the two groups did not differ in their levels of anxiety and depression. The data shows that cognitive impairment in MS is not directly related to the course of the disease. Research may explain differences in other factors including genetics, the degree of brain tissue loss and medications.

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.

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.

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."

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.”
