A Johns Hopkins University-initiated clinical trial is starting to enroll an estimated 900 relapsing-remitting multiple sclerosis (RRMS) patients to assess the benefits of switching therapies to prevent or reduce disability. The TREAT-MS study (NCT03500328) will evaluate whether RRMS patients with disease activity while on a traditional first-line disease-modifying therapy…

Lemtrada (alemtuzumab) can sustain reduced activity and prevent progression of relapsing-remitting multiple sclerosis (RRMS) for more than seven years, clinical data from the CARE-MS extension trial shows. Findings were recently presented in four poster presentations at the 2018 Annual Meeting of the American Academy of Neurology (AAN) in Los Angeles. Lemtrada, marketed by Sanofi Genzyme, is an approved MS therapy that, according to its label, should generally be reserved for patients who have had an inadequate response to two or more other therapies. But the use of the word "generally" opens a window of opportunity “to use Lemtrada as a second-line therapy and potentially first-line therapy,” Barry Singer, MD, director of the MS Center for Innovations in Care at Missouri Baptist Medical Center, said in an email response to questions from Multiple Sclerosis News Today. The treatment was initially tested in two pivotal clinical trials in comparison with a high-dose under-the-skin injection of Rebif (interferon beta-1a) in RRMS patients. Participants were either new to treatment (CARE-MS I, NCT00530348) or had not responded to prior therapies (CARE-MS II, NCT00548405). During these trials, patients received 12 mg of Lemtrada for three or five consecutive days in two annual courses — at the beginning of the study and again one year later. After completing this treatment period, they had the opportunity to participate in a four-year extension study (NCT00930553) during which they could receive the therapy as needed to control their disease. Patients completing the extension could enroll in the five-year TOPAZ trial (NCT02255656) for further evaluation. To date, 80% of the participants (299 patients) from CARE-MS I and 73% from CARE-MS II (317 patients) have completed seven years of long-term follow-up. After completing two initial courses of Lemtrada, 59% of patients from CARE-MS I and 47% from CARE-MS II did not require additional treatment courses with Lemtrada or other disease-modifying therapies during the next six years. Two-thirds of  CARE-MS II patients who required a third Lemtrada course also experienced disability stabilization one year after the last treatment. During the seven years of follow-up, reported annualized relapse rates remained low, and 37% of patients from CARE-MS 1 and 44% from CARE-MS II experienced confirmed improvements in disability. In fact, during this period, only 26% from CARE-MS 1 and 31% from CARE-MS II showed disability worsening. The treatment also had a sustained effect on slowing brain volume loss by the seventh year, with a median yearly brain volume loss of 0.20% or less from the third to seventh year. This effect was found to be even better than that reported during the initial two years of treatment in the pivotal studies (0.59% in the first year and 0.25% in the second year in CARE-MS I, and 0.48% in year one and 0.22% in year two in CARE-MS II). Additionally, evaluation by magnetic resonance imaging (MRI) showed no signs of disease activity during the seven years of follow-up. “The extension study data being presented at AAN illustrate that more than two-thirds of patients did not experience confirmed disability worsening at year seven after initiating treatment with Lemtrada,” Singer said in a press release. “In addition, consistent effects were maintained over time across relapses and MRI outcomes including brain volume loss, even though the majority of patients did not receive any additional treatment over the prior six years.” During the extension studies, the frequency of adverse events was similar to that reported during the pivotal studies. In seven years, three deaths occurred, none of which was considered to be treatment-related. Thyroid adverse events were reported to be more frequent by the third year, but declined thereafter. As Singer noted, "the serious risks of Lemtrada, including serious infusion reactions, serious infections, thyroid disease, kidney disease, low platelets and potential malignancies, must always be discussed with the patient." All patients should also be carefully monitored on a monthly basis for four years after the last treatment course “to screen for autoimmune complications, including low platelet counts, thyroid disease, and kidney disease,” he said. Lemtrada’s long-term effects were shared at the AAN annual meeting in these presentations: “Active RRMS Patients Treated with Alemtuzumab Experience Durable Reductions in MRI Disease Activity and Slowing of Brain Volume Loss: 7-Year Follow-up of CARE-MS II Patients (TOPAZ Study)” “Durable Clinical Outcomes With Alemtuzumab in Patients With Active RRMS in the Absence of Continuous Treatment: 7-Year Follow-up of CARE-MS II Patients (TOPAZ Study)” “Durable Reduction in MRI Disease Activity and Slowing of Brain Volume Loss in Alemtuzumab-Treated Patients With Active RRMS: 7-Year Follow-up of CARE-MS I Patients (TOPAZ Study)” “Durable Clinical Efficacy of Alemtuzumab in Patients With Active RRMS in the Absence of Continuous Treatment: 7-Year Follow-up of CARE-MS I Patients (TOPAZ Study) Lemtrada is approved in more than 60 countries, and has additional marketing applications under review by regulatory authorities worldwide.

Autologous hematopoietic stem cell transplantation, also known as aHSCT, has been shown to be safe and highly effective to treat patients with "aggressive" multiple sclerosis. Tested in 19 patients, transplantation of stem cells was found to induce clinically meaningful improvements in disability. These findings were shared at the 2018 Annual Meeting of the American Academy of Neurology (AAN) in Los Angeles, California. aHSCT uses a patient’s own healthy bone marrow stem cells, in combination with a much less aggressive chemotherapy and/or radiation regimen, to prepare the patient for the transplant. Previous studies have suggested that aHSCT is an effective strategy to treat patients with highly active relapsing-remitting MS (RRMS) who do not respond to available disease-modifying therapies (DMTs), and international guidelines advocate for its use in patients with "aggressive" MS. To further demonstrate the potential of aHSCT as a treatment for "aggressive" MS, a research team evaluated its safety and effectiveness in MS patients who had not been treated previously with DMTs. A total of 19 patients were treated across several clinical centers: seven patients were from Sheffield, U.K., seven from Uppsala, Sweden, four from Ottawa, Canada, and one patient was from Florence, Italy. All patients received aHSCT between May 2004 and May 2017. In addition to aHSCT, patients were treated with BEAM (carmustine, etoposide, cytarabine, melphalan) chemotherapy plus antithymocyte globulin (ATG) to reduce transplant rejection, or with Cytoxan (cyclophosphamide) with ATG, or the triple combination of Cytoxan, ATG, plus busulfan as conditioning regimens. Patients had a median age of 33 years at diagnosis and received the aHSCT by a median time of nine years after symptom onset. They had a median disability score of 6.5 before the treatment, as determined by the Expanded Disability Status Scale (EDSS). After a median follow-up period of 30 months, patients had a median EDSS score of 2.0, which represented a median improvement of 2 points (the higher the score, the worse the patient's disability level). None of the patients had clinical relapse following the transplant of stem cells. Only three patients developed new brain lesions detectable by magnetic resonance imaging (MRI) at the first six-month follow-up evaluation, but no additional new lesions were detected in the following scans. The adverse effects reported during the study were comparable to those previously observed in similar treatments. No deaths related to the treatment were reported. Based on these preliminary results, the researchers concluded that aHSCT is “safe and highly effective in inducing rapid and sustain remission” in highly active MS, and "was associated with a significant improvement of [patient’s] level of disability.” “aHSCT should be considered as first line therapy in patients with ‘aggressive’ MS,” the team concluded. Another study presented at the AAN 2018 meeting further supports these findings, demonstrating the superior effectiveness of aHSCT over conventional DMTs for RRMS.

The National Multiple Sclerosis Society will award $433,800 to 10 high-risk pilot studies that will quickly evaluate new strategies and interventions and enhance knowledge about multiple sclerosis (MS). According to a press release, the award winners will address different aspects of the disease, including potential treatments for fatigue and loneliness, to improve patients' walking abilities, and a strategy to change gut bacteria effects in MS. The year-long Pilot Research Grant program is a way to support early-stage research projects to quickly test their effectiveness. The MS Society also said that additional projects will be awarded this year. Results of a recent survey of approximately 300 pilot grant recipients revealed the program successfully promotes new ideas and brings new researchers to the MS field. About 90 percent of the respondents agreed that the financial support was very important for their research project. In 85 percent of cases, the grant supported new ideas, and in 56 percent it allowed support for additional grants. These pilot grants allow researchers to obtain preliminary data so they can decide to apply for additional funding, if the project looks  promising, or to put the idea to rest.

Argentina has become the first country in Latin America to approve Mavenclad (cladribine) as a treatment for adults with highly active relapsing multiple sclerosis. The Argentinian Administration of Medicines, Food and Medical Technology's approval covered Merck’s cladribine tablet formulation. Merck expects to make the treatment available in the country in the next few months. Mavenclad has already been approved in Canada, Australia, Israel, and Europe. Merck is seeking approval in the United States and other countries. "Having a new MS treatment approved in Argentina is very motivating," Dr. Jorge Correale of the Institute for Neurological Research Dr. Raúl Carrea said in a press release. "Mavenclad allows the patient's immune system to go through a selective immune reconstitution, similar to a reset, and the treatment mechanism is simple because it does not require frequent administration or monitoring," said Correale, head of the institute's neuroimmunology and demyelinating diseases department. Mavenclad is designed to target the immune T- and B-cells that trigger relapsing MS without suppressing the entire immune system. With a maximum of 20 days' treatment over two years, the oral drug promotes long-term inhibition of harmful immune cells, reconstituting the immune system. MS is an autoimmune disease, or one in which the immune system attacks normal tissue as well as invadors. Argentine regulators based their approval on the results of five clinical trials. These were the Phase 3 CLARITY, CLARITY EXTENSION, and ORACLE-MS studies, the Phase 2 ONWARD study, and the long-term PREMIERE study. These trials involved more than 2,700 patients with relapsing MS, some of whom researchers followed for more than 10 years. The trials showed that Mavenclad can significantly reduce MS relapse rates, disability progression and brain atrophy. The treatment is recommended for patients who fail to respond adequately, or are unable to tolerate, other therapies. "We are pleased the Argentinian Administration of Medicines, Food and Medical Technology has approved Mavenclad," said Rehan Verjee, the chief marketing and strategy officer of Merck's biopharma business. "Our goal is to ensure fast access to patients who may benefit from this innovative therapy, and we will be working with payers on obtaining reimbursement as a next step."

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."

Multiple sclerosis patients should be routinely assessed for chronic and, especially, neuropathic pain in order to properly diagnose and treat this condition, which appears to directly affect the degree of a patient's disability, a new study reports. Pain is one of the most disabling clinical symptoms of MS, associated with suffering, distress, and lower quality of life. Many studies have investigated the prevalence of chronic pain in MS patients but with highly varying results: estimates range from 29 percent up to 92 percent. This disparity is likely due to methodological differences between the studies, as well as differences in the studied population. The result is the prevalence of pain in MS is still unclear, and underdiagnoses of pain in this patient population likely. Researchers in Italy conducted a single-center study to determine the prevalence and characteristics of chronic pain, defined as constant pain for more than three months, in a population of MS patients. Pain was evaluated using validated tools, and the results were analyzed in relation to clinical features such as disease duration and disability. In total, 374 MS patients with different disease severities were assessed for pain. Results found an overall prevalence of chronic pain of 52.1, most frequently affecting the lower limbs. Neuropathic pain, which refers to pain resulting from a lesion or disease impacting the sensory nervous system, was the most frequent type of chronic pain, affecting 23.7 percent of the patients analyzed. Pain intensity was also found to be significantly higher in patients with neuropathic pain compared to those with non-neuropathic pain. Researchers measured patients' disability using the Expanded Disability Status Scale. They determined that patients with chronic pain, and especially those with chronic neuropathic pain, had significantly higher EDSS scores (meaning greater disability) than those without such pain. Both these patient groups were also more likely to be on long-term pain medications: 33 percent of MS patients with neuropathic pain, and 24 percent of those with chronic pain. These results indicate that pain is underdiagnosed and undertreated in MS patients, and a factor that may contribute to increased disability. “Our results suggest that clinical disability is higher in MS patients with chronic pain and, in particular, in those with neuropathic pain,” the researchers concluded. “The present study supports the routine assessment of neuropathic pain in MS patients.”

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.

Multiple sclerosis patients who adhere strictly to their medication pay more but stay healthier in the long run than those who don't, a study found. Researchers at Liberty University College of Osteopathic Medicine in Lynchburg, Virginia, analyzed data from 2004 to 2013, including electronic health records, insurance claims and self-reported medication adherence. They based their assessment of health outcomes on inpatient admission, emergency room visits, outpatient appointments  and healthcare costs. In total, 681 participants answered questionnaires about medication adherence and disease outcomes, including the Multiple Sclerosis Impact Scale and the Kurtzke Expanded Disability Status Scale. Also used was the Treatment Satisfaction Questionnaire for Medication to assess satisfaction with the medication taken. Patients who took their medicines most rigorously reported 14 percent less severe physical impact of MS, and 17 percent less severe psychological impact than those with low adherence. These patients also reported a 12 percent decrease in disability level, and believed their treatment plan was 7 percent more effective. However, the total overall costs were higher for patients who adhered to their doctor's orders. The researchers said it's more difficult to detect improvements in health outcomes for MS than for other chronic illnesses. This is partly because the only test for changes in disease status is brain imaging, which is expensive and not done routinely. Furthermore, brain imaging only detects new lesions following a relapse, which cannot be compared to previous or future imaging in a quantifiable way. In fact, no simple tests exist for measuring disease severity in MS as there are in other chronic diseases, making it difficult to determine whether treatment benefits justify their cost.
