clinical trials

Three-fourths of relapsing multiple sclerosis patients who took two short courses of Mavenclad over two years remained relapse-free for four years, according to newly published data from the medication's Phase 3 extension trial. Moreover, patients who took Mavenclad during the first two years and then a placebo for the next two years fared similarly to those who took Mavenclad for the entire four-year period. The European Commission on Aug. 25 approved Mavenclad — developed by Merck KGaA (known as EMD in North America) — to treat relapsing forms of MS in Europe. It based that approval on data from the Phase 3 CLARITY, CLARITY EXTENSION, and ORACLE-MS trials, as well as the Phase 2 ONWARD trial, and the ongoing long-term PREMIERE study. Besides showing the long-term impact of two short courses of Mavenclad — patients took tablets for a maximum of 20 days over two years — this latest study showed that continuing treatment into the third or fourth year offered no additional benefits. This finding supports Merck’s earlier studies, which suggested that Mavenclad resets the immune system. This is a stark contrast in treatment approach to most approved MS drugs which work by suppressing either T- or B- immune cells over the long term. Researchers also deemed safety to be similar in the two groups. Most adverse events were mild or moderate, and most patients who had their B-cells and T-cells depleted in the first part of the study had normal, or nearly normal, levels at the end of the extension. Shingles were most common in patients who received the highest cumulative dose of the drug, affecting 4.8 percent of participants. But in the remaining treatment groups, rates of the viral infection were similar at 1.1 to 2 percent, researchers said. Besides Merck's own studies, an independent study recently demonstrated that Mavenclad also improves patients’ quality of life. As such, the company plans to file regulatory approval for Mavenclad in the United States and elsewhere.

Gilenya decreased relapses in children and adolescents with multiple sclerosis in the phase 3 PARADIGMS trial, according to the therapy's developer, Novartis. The Swiss company will present the trial's results at the 7th Joint ECTRIMS-ACTRIMS meeting, set for Oct. 25-28 in Paris. The study addressed the safety and efficacy of an oral, once-daily dose of Gilenya in 215 MS patients aged 10 to 17. Participants received 0.5 mg or 0.25 mg of Gilenya, according to their body weight, and results were compared with those of intramuscular Avonex (interferon beta-1a given once weekly). The trial — conducted at 87 sites in 25 countries — was designed in partnership with the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA) and the International Pediatric Multiple Sclerosis Study Group. Gilenya led to a "clinically meaningful decrease in the number of relapses" over a period of up to two years, compared to Avonex, according to the trial. The safety results of Gilenya matched those observed in previous trials, with adverse events more likely among the Avonex group. Importantly, the PARADIGMS trial is the first-ever randomized, controlled Phase 3 study of a disease-modifying therapy in pediatric MS. No treatment is currently available for children and adolescents with MS. Novartis will now complete a thorough evaluation of the results and later submit Gilenya for approval by regulatory agencies. It will also extend the study to a five-year period.

TG Therapeutics will discuss ublituximab's ability to deplete B-cells linked to multiple sclerosis and to reduce inflammatory brain lesions at the 7th Joint ECTRIMS–ACTRIMS Meeting in Paris next month. The three presentations will cover preliminary results of a Phase 2 clinical trial of ublituximab's safety and effectiveness as a treatment for relapsing forms of MS, the company said in a press release. The conference will be Oct. 25-28. Dr. Amy E. Lovett-Racke of Ohio State University will discuss ublituximab's ability to decrease B-cells associated with MS after six months of treatment. Ublituximab is an antibody that targets B-cells carrying the CD20 protein on their cell surfaces. These cells are thought to play a role in MS development. Dr. Matilde Inglese of the Icahn School of Medicine at Mount Sinai in New York will discuss ublituximab's ability to decrease study participants' inflammatory brain lesions. And Dr. Edward Fox of Central Texas Neurology Consultants, the trial's principal investigator, will do a poster-session presentation on the study's patient characteristics and preliminary results as a whole, including safety. The ongoing Phase 2 trial is still recruiting patients with relapsing forms of MS. Researchers are randomly assigning participants to receive intravenous infusions of either ublituximab or a placebo. One of the study’s primary goals is to see how well ublituximab depletes B-cells 28 days after the start of treatment. Another primary goal is to see how safe the therapy is, with the measurement being treatment-related adverse events that patients experience over six months. Ublituximab’s ability to reduce relapses will be a secondary measure of the trial. Researchers will assess it after 48 weeks of treatment. Fox, who is the director of the Multiple Sclerosis Clinic of Central Texas, and a clinical assistant professor at the University of Texas Medical Branch in Round Rock, made a ublituximab presentation at the 3rd Congress of the European Academy of Neurology in June. It revealed that the therapy nearly depleted B-cells only four weeks after treatment started. Earlier data suggests that ublituximab can be administered in only one hour. Ocrevus, the only approved MS therapy that targets B-cells with CD20, requires 3 1/2 hours. Although the Phase 2 trial is continuing, the data generated so far supports plans for two Phase 3 trials, TG Therapeutics said. They will randomize patients to receive either ublituximab or Aubagio. The trials, which the company hopes to start by the end of September, will be conducted under a Special Protocol Assessment agreement with the U.S. Food and Drug Administration. It allows the FDA to evaluate the design and population size of a trial a company intends to use to seek a drug's regulatory approval. The FDA has refused to approve therapies whose trial design it believed to be flawed. Obtaining a design sign-off before a trial improves the chance of a treatment being approved if it meets the study's objectives.

A Phase 2b trial assessing the experimental retroviral-targeting treatment GNbAC1 in patients with relapsing-remitting multiple sclerosis (RRMS) failed to meet its primary goal of reducing brain lesions and other signs of brain inflammation within six months. But researchers at GeNeuro and Servier — the two European companies that jointly developed the drug…

I was surprised to see that a study of a potential MS drug labeled MD1003 is still accepting participants. It’s a study that I’d love to take part in, if only I was a few years younger. MD1003 is a high dose of biotin, a form of…

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.

A group of experts recently concluded that clinical trials are the best way to explore whether cell-based therapies are viable options for treating multiple sclerosis. In a newly published article, MS researchers reviewed evidence on a range of cell therapies, including stem cell transplants and delivery or stimulation of various cell types. Clinical trials, the panel argued, would be the optimal way to examine which types of cells should be used, how they should be delivered, and the types and disease stages the treatments are suitable for. The article focused on four types of cell-based treatments: autologous stem cell transplants, mesenchymal and related stem cell transplants, use of drugs to manipulate stem cells in the body to boost their ability to repair, and transplants of oligodendrocyte progenitor cells to trigger new myelin production. Loss of the myelin that protects neurons is a hallmark of MS. Such treatments hold promise to attain what current disease-modifying therapies in MS have not: halting the disease without lifelong treatment that has potential side effects, and regenerating damaged tissue. In addition to reviewing the evidence surrounding cell-based treatments, the expert group focused on the availability of the treatment options outside of controlled trials. “Media attention has resulted in some cases of misrepresentation and exaggeration of therapeutic claims for cell-based therapies for multiple sclerosis and other diseases,” the team wrote. This has caused patients to seek the treatments — paying out-of-pocket — at unregulated clinics. The panel noted that several drugs in development, including opicinumab, are aimed at promoting remyelination. In addition, drugs that are already approved for other conditions might have remyelinating properties, and might be repurposed to treat MS. Although studies are ongoing, the panel noted that it is unclear if the drugs do promote remyelination. Despite ongoing research and — in some cases — clinical use of cell-based therapies for MS, these treatments should be considered experimental, the expert group concluded. They again underscored the importance of clinical trials in providing a controlled environment for patients wishing to have cell therapy, as well as a source of evidence for the feasibility of these approaches.

Kezar Life Sciences announced that it is planning to move ahead with clinical testing of KZR-616, a potential treatment for multiple sclerosis (MS) and other autoimmune diseases and inflammatory disorders. The company recently concluded a Phase 1 safety study of the treatment, and raised $50 million in investment funding to support its development. KZR-616 is a first-in-class selective immunoproteasome inhibitor, meaning it works by blocking abnormal protein degradation. Cells eliminate proteins by sending them to a specialized cell compartment known as the proteasome. In immune cells, the proteasome is called immunoproteasome, and it regulates several selective inhibitors and participates in the regulation of the immune response associated with inflammatory diseases such as MS, rheumatoid arthritis, Crohn's disease, and lupus. "We are pleased with the results of our healthy volunteer study, and grateful for the support of such an excellent group of investors to finance our upcoming clinical trials," John Fowler, Kezar Life Sciences’ CEO, said in a news release. "The strong demand for this financing reflects growing excitement for the potential of immunoproteasome inhibition in treating autoimmune disorders and recognizes the clear leadership position enjoyed by Kezar." The Phase 1 trial enrolled 82 healthy subjects, who were assigned to receive either KZR-616 or placebo. In total, 61 volunteers were given KZR-616 as single or multiple doses at varying dose levels to identify the optimal dose for both tolerability and proteasome inhibition. Results will be presented at the American College of Rheumatology's Annual Meeting to be held in San Diego in November. "These initial clinical trial results demonstrate that KZR-616 is achieving the desired levels of immunoproteasome inhibition that correlate with anti-inflammatory activity seen in laboratory models,” said Christopher Kirk, PhD, company president and CSO. “By selectively targeting the immunoproteasome, we believe we can avoid the toxicities associated with dual proteasome inhibitors like Velcade and Kyprolis." The Series B financing round was led by Cormorant Asset Management and Morningside Venture and raised $50 million to support the development of KZR-616. Kezar announced it has the support of new investors, including Cowen Healthcare Investments, Pappas Ventures, Qiming Venture Partners, and Bay City Capital. "Cormorant is pleased to support Kezar as it enters an exciting series of patient studies, the first ever with a selective immunoproteasome inhibitor," said Bihua Chen, founder of Cormorant Asset Management. "While much work remains, I believe KZR-616 has the potential to be a transformative treatment in autoimmunity."

A new analysis of Phase 2 clinical data on Innate Immunotherapeutics’ investigational drug MIS416 to treat secondary progressive multiple sclerosis has confirmed that the drug failed to improve neuromuscular function or patient reported outcomes. The initial evaluation of data obtained from the one-year trial, announced in June, showed disappointing results. These results, gleaned from 70 patients who were randomly designated to receive either weekly injections of MIS416 or a placebo control, failed to demonstrate significant differences or clinically meaningful improvements in patients treated with MIS416 compared to those in the control group. After this initial setback, the Australian company sponsored an additional analysis of the trial results to identify any potential subgroup of clinical responders that could benefit from MIS416 and who might have been masked in the first population-based analysis. However, this post-hoc analysis also failed to show any positive effects of MIS416. Although the detailed report of this second analysis has not yet been released, the Sydney-based company conceded that the final outcome will not change. "All previous reports of MIS416 making a meaningful difference in the lives of many patients must either be dismissed as a very robust placebo effect or the trial failure is attributable to some other reason. It is my view that there may be other reasons," Innate CEO Simon Wilkinson said in a press release. "Patients with SPMS have a complex mix of symptoms and their disease can't be monitored by a simple blood test or MRI scan," he added. "We used the best assessment tools available as recommended by expert practitioners in MS, but we suspect they weren't sensitive enough to pick up the small but potentially significant changes that can lead to a substantial impact on patients' activities of daily living and quality of life." The lack of efficacy of MIS416 shown by the trial results is inconsistent with previous clinical experience, and the benefits reported by those receiving MIS416 for the past eight years.

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."

Innate Immunotherapeutics' MIS416 has failed to help secondary progressive multiple sclerosis (SPMS) patients in a Phase 2 clinical trial. The company said it will continue testing the therapy, made up of natural compounds, to see if it can benefit any MS subgroups. Trial participants who received MIS416 had no meaningful improvements in neuromuscular function or the outcome of their disease, compared with those who took received a placebo. “It is disappointing that these results don’t show benefit for people with secondary progressive MS, for whom there are few treatment options,” Dr. Bruce Bebo, executive vice president of research at the National MS Society, said in a news release. Scientists hoped the injected therapy would modulate the activity of immune cells that affect the protective myelin coating around nerve cells, decreasing the inflammation and brain tissue damage associated with MS. Deterioration of the coating is a hallmark of the disease. The one-year trial (NCT02228213) tested the safety and effectiveness of MIS416 on 93 patients with SPMS in Australia and New Zealand. The patients randomly received MIS416 or a placebo once a week. There were no differences in the groups' scores on a disability index — the expanded disability status scale — or in brain volume changes detected by magnetic resonance imaging. In addition, there were no differences between in disease outcomes that patients reported. The self-reported barometers included the Multiple Sclerosis Impact Scale, the Neurological Fatigue Index, and the Brief Pain Inventory. "I am extremely disappointed by this outcome," Professor Pam McCombe, a principal trial investigator, said in a company press release. "Looking for measurable changes in patients with progressive MS using the assessment tools currently at our disposal is frustrating and complicated. We were hopeful that MIS416 would be an option to treat this group of patients who currently do not have effective treatment options." In addition to MIS416 failing to be effective, the group who received it had more treatment-related adverse events than the placebo group. The events were mainly related to the first dose, Innate said. The main problems were fever, chills, and muscle weakness. The company has been providing MIS416 to Australian MS patients under a compassionate use program. It said it will continue evaluating the safety and tolerability of the drug to see if it helps any subgroups of patients. Those findings will determine the future of the compassionate use program, it said. “These results are a shock, and definitely not what we were expecting based on our previous clinical experience with MIS416 and the reporting of treatment benefits we have received from many compassionate use patients over an extensive eight-year period," said Simon Wilkinson, Innate Immunotherapeutics' chief executive officer. "These data will be as distressing to them as they will be for all the stakeholders who were relying on the outcome of this study."
