RRMS

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.

Treatment with Ocrevus (ocrelizumab) is linked to a reduced immune response to vaccinations in patients with relapsing multiple sclerosis (MS), according to a Phase 3 trial. These results were recently presented at the 2018 American Academy of Neurology (AAN) Annual Meeting in Los Angeles in a presentation titled, “Effect of Ocrelizumab on Vaccine Responses in Patients With Multiple Sclerosis.” Genentech’s Ocrevus is an approved MS therapy that targets the CD20 protein located on the surface of B-cells, targeting the cells for destruction. B-cells are immune system cells involved, for example, in the production of antibodies necessary to fight off infection. At the AAN meeting, researchers reported that in MS patients, treatment with Ocrevus decreased the ability of B-cells to activate other immune cells, improving the rate of MS attacks. Penn Medicine neurologist Amit Bar-Or, MD, presented these findings, which showed that interactions between different classes of immune cells, such as B- and T-cells, promote MS attacks. Vaccination against infections is an important part of the management of patients with MS. So, in a second study (NCT02545868), researchers investigated the impact treatment with Ocrevus has on patient response to vaccines. They recruited 102 patients with relapsing MS and randomized them in two groups. In group A, 68 people received a single dose of 600 mg Ocrevus (administered into the blood); in group B, 34 patients received no disease-modifying therapy or interferon-beta. All patients were then administered vaccines for tetanus, seasonal flu, and pneumococcus. Patients in group A received the vaccines 12 weeks after they were treated with Ocrevus, while group B patients received the vaccines on day one. Researchers also tested patients’ response to a novel protein (an antigen) never "seen" by their immune system, called keyhole limpet hemocyanin (KLH) neoantigen. The vaccinations led to an immune system response in all patients, but the level of response in patients treated with Ocrevus was lower. A positive response to the tetanus vaccine at eight weeks after treatment was 23.9% in group A (Ocrevus) compared with 54.5% in group B (no treatment); the response to pneumococcus vaccination was 71.6% in group A and 100% in group B. After four weeks of treatment, the levels of antibodies against the different strains of the flu virus were lower in Ocrevus-treated patients than in the control group, ranging from 55.6% to 80.0% in the Ocrevus group compared with 75.0% to 97.0% in the controls. The immune response to the neoantigen KLH was also decreased in the Ocrevus group. "This study shows that while people with MS treated with ocrelizumab [Ocrevus] can still mount vaccine responses, it's not nearly as strong as prior to treatment," Bar-Or said in a press release. "While antibody responses were reduced in the ocrelizumab treated patients, they still responded to a certain level," he said. "This is valuable information in terms of seasonal vaccines such as the flu — it appears safe for patients taking ocrelizumab to get vaccinated and vaccination is likely to provide them with at least some protection from such infections." These findings correlate with standard guidelines that advise patients to undergo vaccinations six weeks before they start treatment with Ocrevus.

Cigarette smoking increases the relapse rate in patients with relapsing-remitting multiple sclerosis who are being treated with interferon-beta, a study suggests. The findings suggest that RRMS patients who smoke may have fewer relapses if they quit. An article on the results, “Smoking affects the interferon beta treatment response in multiple sclerosis,” appeared in the journal Neurology. A number of studies have looked at the link between environmental and lifestyle factors and the risk of developing MS. These factors include how much sunlight and vitamin D patients get and whether they have an Epstein-Barr virus infection. Cigarette smoking is a well-documented risk factor in MS, but most of the studies on it have focused on the link between smoking and MS, or the link between smoking and the  disease's progression. “Studies that addressed the relationship between smoking and disease activity in RRMS are rarer,” the researchers wrote. The team decided to investigate whether smoking during interferon-beta treatment would affect relapse rates. Previous research had set the stage for the study by showing a link between smoking and gene mutations that make people more susceptible to developing MS. The mutations were in the HLA and NAT1 genes. The team looked at DNA from 834 RRMS patients in the Danish Multiple Sclerosis Biobank who were treated with interferon-beta. Well-known brand names of the treatment include Rebif, Avonex, and Plegridy. There are also other brand names and biosimilar drugs. Researchers also looked at patients’ medical records two years before they started on interferon-beta. Before making any conclusions on possible links between smoking and patients' relapse rate, the team adjusted for patients’ sex, age at the start of treatment, and number of relapses in the two years before treatment began. Their key conclusion was that smoking increased by more than a quarter the number of relapses in patients on interferon-beta therapy. “Each pack of cigarettes more per day during IFN-β [interferon-beta] treatment increased the number of relapses by 27%,” the team wrote. The researchers found no association among smoking, relapses, and mutations of the HLA or NAT1 genes. “Our results confirm that lifestyle factors are important in MS, suggesting that smoking cessation may be associated with a reduction in disease activity,” they wrote. “Although not formally proving that smoking cessation will decrease disease activity in RRMS, the results should encourage physicians to inform patients with MS about the harmful effect of smoking and increase focus on smoking cessation,” they observed.

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."

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.
