disease progression

Long-term treatment with disease-modifying therapies (DMTs) appears to lessen the risk of disease worsening in relapsing-remitting multiple sclerosis (RRMS) patients, an 18-year follow-up study suggests. But these therapies were not seen to benefit those who had progressed to secondary progressive multiple sclerosis (SPMS). The study, “Onset of secondary…

Inhibition of the neuroactive opioid growth factor (OGF) alters the blood levels of important pro- and anti-inflammatory proteins in mice with multiple sclerosis (MS)-like disease. The recognition of this regulatory response may represent a new way to monitor disease progression and treatment response in MS. These findings were reported in a study published in the journal Experimental Biology and Medicine, titled “Modulation of the OGF–OGFr pathway alters cytokine profiles in experimental autoimmune encephalomyelitis and multiple sclerosis.” The study was led by researchers at Penn State University. Understanding the underlying mechanisms involved in MS and finding ways to tackle them is crucial for improving early diagnosis, monitoring disease progression, and patient care. For many years, researchers at Penn State have been focused on understanding the benefits of low-dose naltrexone and its relation with OGF in health and disease, including MS. Naltrexone is marketed with the brand name ReVia, among others. This drug is used routinely off-label to treat MS and other autoimmune diseases, as it has demonstrated to it can reduce fatigue, lessen pain, and confer a general feeling of well-being to patients. Its mode of action is not fully understood, but it is known to block the interaction of the neuroactive OGF with its receptor OGFr. In addition, low-dose naltrexone and OGF were shown to prevent the proliferation of active immune cells in mice with MS-like disease. To further evaluate the role of OGF and low-dose naltrexone in MS, researchers treated mice with naltrexone and analyzed its impact on blood levels of pro- and anti-inflammatory signaling proteins (cytokines). Results showed that after 10 days, MS mice had increased levels in seven out of 10 tested cytokines. Treatment with OGF or low-dose naltrexone was found to specifically increase the levels of the pro-inflammatory IL-6 cytokine, and significantly reduce the levels of anti-inflammatory IL-10 protein. Two other pro-inflammatory proteins, TNF-α and IFN-γ, also were found to be increased in MS mice compared to healthy animals. While TNF-α levels were unaltered upon OGF or low-dose naltrexone treatment, IFN-γ was reduced at 10 days, but still present at higher-than-normal levels after 20 days of therapy. To validate its findings, the team analyzed the levels of the identified signaling proteins in blood samples collected from 14 MS patients and eight non-MS volunteers. Six MS patients were undergoing treatment with Copaxone (glatiramer acetate), and four of them had relapsing-remitting MS (RRMS). Four other RRMS patients and one primary progressive MS (PPMS) patient were receiving Copaxone plus low-dose naltrexone; three RRMS patients were receiving low-dose naltrexone alone. The analysis revealed that IL-10 serum values were comparable between non-MS controls and all MS patients on low-dose naltrexone alone, or Copaxone alone. Patients treated with both Copaxone and naltrexone presented a broad range of IL-10 serum values “that were significantly different from MS subjects receiving LDN [low-dose naltrexone] only,” the researchers wrote. In contrast, IL-6 cytokine was found to be significantly elevated in MS patients treated only with Copaxone compared to patients receiving low-dose naltrexone alone or together with Copaxone. “These data suggest that IL-6, a pro-inflammatory marker is very responsive to OGF and LDN therapy, and thus may be involved in other mechanistic pathways associated with the OGF-OGFr axis,” the researchers wrote. "Identification of inflammatory cytokines that have expression profiles mediated by OGF or LDN [low-dose naltrexone] therapy increase our panel of potential biomarkers for MS,” Patricia McLaughlin, PhD, said in a press release. McLaughlin is professor of neural and behavioral sciences at Penn State, and senior author of the study. “We hope that continued research will identify more specific cytokines and allow us to assemble a reliable panel of minimally invasive biomarkers related to the etiology and progression of MS," she added. Additional long-term human and mouse studies are needed to further evaluate if IL-6 and IL-10 are “appropriate markers to monitor progression of MS,” the researchers emphasized. Still, the team believes this study demonstrates that at least IL-6, IL-10, TNF-α, and IFN-γ, together with OGF, can be useful biomarkers to monitor MS. "McLaughlin and colleagues have researched OGF signaling for several decades, and this seminal discovery of dysregulation in OGF expression in MS patients, and animal models, is very exciting and could lead to prognostic biomarkers for this autoimmune disorder," concluded Steven R. Goodman, PhD, editor-in-chief of the journal in which the study was published.

Sweden's Active Biotech said its experimental therapy Laquinimod failed to meet the primary and secondary objectives of Phase 2 clinical trial evaluating the drug's potential to treat primary progressive multiple sclerosis. Laquinimod, also known as Nerventra or ABR-215062, was developed by Active Biotech and Israel's Teva Pharmaceutical Industries. The drug targets inflammation and degeneration in neurological tissue. Preclinical studies using animal models of multiple sclerosis showed that laquinimod regulated inflammatory and immune responses in these animals, reducing disease progression. The ARPEGGIO Phase 2 study aimed to evaluate laquinimod's efficacy, safety and tolerability in PPMS patients. Its primary endpoint was brain atrophy as defined by percent brain volume change. Secondary goals included time to disability progression, change in timed 25-foot walk, and number of new T2 lesions. The multicenter, randomized, double-blind, placebo-controlled trial enrolled 374 individuals. Initially, the study aimed to evaluate two doses of laquinimod — 0.6 and 1.5 mg/day — in PPMS compared to placebo. However, the highest dose was discontinued in January 2016 after some participants reported adverse cardiovascular events. In a Dec. 1 press release, Active Biotech said the lower dose of laquinimod failed to slow both the rate of brain atrophy and disease progression. “There was, however, a reduction in new T2 lesions observed in patients treated with laquinimod 0.6 mg,” said the company's president and CEO, Helén Tuvesson. The trial revealed a similar safety profile to that observed in previous studies in relapsing-remitting MS patients (RRMS). The most common adverse reactions were headache, nasopharyngities, upper respiratory tract infection,and back pain. Results of the ARPEGGIO trial will likely be presented at a future scientific conference and published in a scientific journal. Earlier this year, Active Biotec stopped developing laquinimod as a potential RRMS treatment after a Phase 3 study failed to achieve its primary goal: slowing disease progression. Laquinimod is also being evaluated as a potential therapy for Huntington’s disease in a Phase 2 clinical trial.

MSBase and icometrix have joined efforts in a large-scale project to identify imaging markers of multiple sclerosis (MS) that could help diagnose the disease in its early stages. The combination of magnetic resonance imaging (MRI) information collected from MS patients with clinical information from the MSBase Registry can offer new insights in disease progression, potentially leading to new predictive tools for MS. It may also promote more standardized use of imaging measures in clinical practice. With more than 52,000 MS patients, the MSBase Registry is an international database committed to collecting patients’ information as well as sharing, tracking and evaluating overall outcome data in MS and other neurological conditions. Until now, the MSBase Registry included only descriptive information regarding patients' imaging analysis results, with no access to full imaging data. This joint, large-scale project will include MRI scan data routinely acquired in clinical setting taking advantage of icometrix’s software platform, MSmetrix. “We wish to unlock the power of MRI for personalized monitoring in MS," Helmut Butzkueven, director of MSBase, said in a press release. "The MSBase Scientific Leadership group has selected MRI integration as the top strategic priority for MSBase. We believe that already conducted MRI scans represent an enormous missed opportunity, because advanced measurements to assess change over time from these scans are not currently in practical use.” Butzkueven said MSBase "will test the predictive power of this unlocking of MRI data in the first phase," with a total of 10,000 MRI data points in at least 3,000 MS patients from all over the world. The project is expected to identify disease progression markers that could help detect early signs of MS by MRI evaluation. This investigator-initiated collaboration between icometrix and the MSBase Foundation is being supported by three global pharmaceutical giants: Novartis, Biogen and Roche. “MRI measures play an essential part in the complex puzzle of MS,” said Danny Bar Zohar, global head of neuroscience development at Novartis. “Partnering with MS Base and icometrix in this exciting project will bring the acquisition of high-quality real world data to the next level, ultimately improving the outcome of people living with MS.”
