#ACTRIMS2018 – Oryzon Enrolls First Patient in SATEEN Trial, Presents New Data at MS Meet

Oryzon Genomics has enrolled the first multiple sclerosis patient in its Phase 2a SATEEN clinical trial investigating the therapy ORY-2001. The Spanish company will also present new results from preclinical models of MS treated with ORY-2001 at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2018, set for Feb. 1-3 in San Diego. ORY-2001 is an epigenetic therapy, meaning it targets the expression and activity of genes. The drug inhibits two particular molecules, LSD1 and MAOB, and was previously shown to reduce cognitive impairment and neuroinflammation in preclinical models, including in a mouse model of MS — the experimental autoimmune encephalomyelitis (EAE) model. The therapy was also shown to have neuroprotective effects. During ACTRESS 2018, Oryzon's chief scientific officer, Tamara Maes, will present a poster, "ORY-2001 reduces inflammatory cell infiltration in the Theiler’s murine encephalomyelitis virus model and highlights the epigenetic axis in MS.” “In previous reports we showed that ORY-2001 reduces the clinical score, lymphocyte egress, immune cell infiltration and inflammation protecting the spinal cord from demyelination in a murine MS-EAE model,” Maes said in a press release. “Here we provide data on the efficacy of ORY-2001 in the Theiler’s murine encephalomyelitis virus model for multiple sclerosis." In a second poster, "ORY-2001 in multiple sclerosis: first clinical trial of a dual LSD-1/MAOB inhibitor,” Roger Bullock, Oryzon's chief medical officer, will detail the Phase 2a trial, SATEEN, testing ORY-2001 in patients with relapsing-remitting or secondary progressive MS over a 36-week period, followed by an open-label extension. “Our first patient enrolled in SATEEN signals a new landmark for the clinical development of this drug in different neurological indications,” said Bullock. “This is the first epigenetic approach in this disease, and we hope that it will contribute to enlarge and improve the therapeutic options for patients afflicted by MS."

MS Patients’ High Osteopontin Protein Levels Make It a Potential Biomarker for the Disorder, Study Reports

Multiple sclerosis patients have high levels of a protein called osteopontin in their cerebrospinal fluid and blood, making it a potential tool for diagnosing the disease and predicting its course, a study suggests. The research, “Osteopontin (OPN) as a CSF and blood biomarker for multiple sclerosis: A systematic review and meta-analysis,” was published in the journal PLOS One. Researchers wanted to know if levels of osteopontin in cerebrospinal fluid and blood could be a reliable biomarker for MS. To arrive at answer, they “conducted a systematic review and meta-analysis" of studies that had measured the protein's levels in cerebrospinal fluid and blood "in MS patients and controls." The team searched for studies in three databases — PubMed, Web of Science and Scopus. Out of 27 that met their criteria, they used 22 in the meta-analysis. All four types of MS were represented in the studies — clinically isolated syndrome, relapsing-remitting MS, secondary progressive MS, and primary progressive MS. There were three types of controls in the articles — healthy people, people with non-inflammatory neurological disorders, and people with inflammatory neurological disorders. Researchers' first observation was that all of the MS patients had higher levels of osteopontin than controls. The protein's levels were significantly higher in relapsing-remitting MS patients than in those with clinically isolated syndrome, the group with the lowest osteopontin levels. Levels were similar in the other types of MS. Patients with an active disease had significantly higher levels of the protein in their cerebrospinal fluid than those with a stable disease. The results supported previous studies' findings that osteopontin levels are higher than normal in the cerebrospinal fluid and blood of MS patients, strengthening the notion that it could be used as a biomarker for MS. “Given the fact that OPN [osteopontin] levels are higher during relapses, we think that by monitoring this biomarker,  we might be able to predict the disease course," the team wrote. "We propose that developing drugs modulating OPN concentration may be a new treatment strategy for MS."

Human Vaccines Project Studies Aim to Unveil Workings of Immune System

Scientists announced positive and encouraging outcomes from two clinical studies — running as part of the larger Human Vaccines Project — aiming to unravel the mechanisms that underlie our immune system’s ability to fight disease. The results are expected to shed light on unknown aspects of the immune system that scientists at the Human Vaccines Project, a public-private partnership, hope to translate into new trials for diseases linked to the immune system, such as multiple sclerosis. Results from the trials — the Human Immunome Program and the Immunity to Hepatitis B Vaccine study — were recently presented at the World Vaccine and Immunotherapy Congress in San Diego, California. In the ongoing Human Immunome Program, researchers are trying to fill a major knowledge gap in the components and mechanisms of the immune system that allow it to recognize various threats, from viruses, parasites and bacteria to cancer cells. They are using blood samples from healthy people to analyze, at an unprecedented depth, the whole repertoire of genes that make up the surface receptors of immune B- and T-cells, the core cells of the immune system’s defence mechanisms. Results will likely advance how scientists diagnose and treat various diseases, and could prompt the development of new, improved vaccines. "We are studying the immune systems of healthy individuals to identify common elements, which could be important for facilitating new and improved vaccines," James E. Crowe Jr., MD, director of Vanderbilt University Medical Center's Vaccine Center, the leading scientific institution of the Human Immunome Program, said in a press release. Researchers will cross the sequencing information with participants' microbiome composition — the natural community of microbes that reside in an organism and are key for a healthy immune system — and other health and sociodemographic characteristics. "We also plan to expand these studies to complete the catalog across different demographics and geographies and compare healthy subjects with individuals with immune-mediated diseases such as multiple sclerosis, cancer and Alzheimer's, which could also reveal novel diagnostic markers," Crowe said. The second study, the Immunity to Hepatitis B Vaccine trial — currently recruiting participants — aims to understand why some people achieve protection against Hepatitis B after a single vaccine shot, while others require up to three immunizations to acquire full immunity. Understanding why the immune system responds differently in individuals can help researchers improve existing vaccines and potentially lead to one-shot vaccines that provide long-term immunity for all populations. Researchers in this study are analyzing genes belonging to the innate-immune system — a general immune system response, not one tailored to specific threats — and observing that activation of these genes in certain immune cells can predict who will be a responder after a single shot of the Hepatitis B vaccine. Preliminary results of the Immunity to Hepatitis B Vaccine study were delivered in two separate sessions at the congress. One was given by Manish Sadarangani, director of the Vaccine Evaluation Center of the University of British Columbia and BC Children's Hospital Research Institute, and the by and Richard Scheuermann, director of the J. Craig Venter Institute in La Jolla, California. "These preliminary data points toward strategies to understand why some people respond better to vaccines than others," Sadarangani said. "Using single cell analyses, we now have the opportunity to probe vaccine-induced responses more effectively, to not only learn what happens immediately after vaccination, but to monitor responses over time and utilize machine learning to eventually predict the human immune response to vaccines," added Scheuermann. Wayne C. Koff, president and chief executive officer of the Human Vaccines Project, emphasized that researchers are optimistic with the results obtained so far, as they "provide important insights into the scale and complexity of the human immune system and how vaccines confer protective immunity." "With our network of academic and corporate partners, we aim to build on these findings and decode the human immune system, giving the world the tools required to advance the development of future vaccines and therapies to defeat major global diseases," Koff concluded.

Probiotics Consumption May Improve Certain Disease Parameters in MS Patients, Study Suggests

Probiotics may improve the health of people with multiple sclerosis (MS) by reducing disability and improving inflammatory and metabolic parameters, an Iranian study shows. Live microorganisms linked to health benefits, known as probiotics, have long been known to help chronic disease patients. In a previous study of people with major depressive disorder, probiotics treatment for eight weeks improved patients’ depression and metabolic parameters. More recently, authors investigated the impact of probiotics on a group of MS patients, looking not only at mental health and metabolic indicators, but also disability scores. Researchers at Tehran's Shahid Beheshti Hospital recruited 60 MS patients, divided them in half, and assigned 30 to take a probiotic capsule and 30 a placebo once a day for 12 weeks. The probiotic contained the healthy bacteria Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium bifidum and Lactobacillus fermentum. Researchers measured patients’ health parameters and disability scores at baseline and after treatment. The results showed that probiotic intake after 12 weeks improved MS patients' disability scores (assessed by the expanded disability status scale, EDSS) when compared to placebo controls. Although this improvement was statistically significant, it was not clinically significant — which is defined as a change of 1.0 point or more at EDSS levels less than 5.5, or 0.5 point or more at EDSS levels greater than 5.5). Moreover, benefits were also detected in several mental health parameters – Beck Depression Inventory, general health questionnaire-28 (GHQ-28), depression anxiety and stress scale. Consuming probiotic capsules also significantly decreased insulin levels and high-density lipoprotein (HDL) cholesterol in circulation, researchers also found. It also lowered certain markers of inflammation and oxidative stress, such as serum high-sensitivity C-reactive protein (hs-CRP) and malondialdehyde (MDA).
