Abstract
Neuroinflammation is associated with disorders of the nervous system, and it is induced in response to many factors, including pathogen infection, brain injury, toxic substances, and autoimmune diseases. Astrocytes and microglia have critical roles in neuroinflammation. Microglia are innate immune cells in the central nervous system (CNS), which are activated in reaction to neuroinflammation-inducing factors. Astrocytes can have pro- or anti-inflammatory responses, which depend on the type of stimuli presented by the inflamed milieu. Microglia respond and propagate peripheral inflammatory signals within the CNS that cause low-grade inflammation in the brain. The resulting alteration in neuronal activities leads to physiological and behavioral impairment. Consequently, activation, synthesis, and discharge of various pro-inflammatory cytokines and growth factors occur. These events lead to many neurodegenerative conditions, such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis discussed in this study. After understanding neuroinflammation mechanisms and the involvement of neurotransmitters, this study covers various drugs used to treat and manage these neurodegenerative illnesses. The study can be helpful in discovering new drug molecules for treating neurodegenerative disorders.

Abstract
BACKGROUND Every patient diagnosed with definite multiple sclerosis (MS) should begin disease modifying therapies. Cinnomer® contains 40 mg glatiramer acetate (GA) and is available in prefilled syringes and autoinjector devices. METHODS A phase IV multicenter study was conducted to explore the safety and effectiveness of Cinnomer® in the treatment of MS. Study-related data were collected for 14 months. RESULTS Totally, 368 Iranian relapsing-remitting MS patients in nine cities were enrolled. The patients were either treatment naïve (n=191) or switchers (n=177). Cinnomer® treatment was associated with a significant reduction in annual relapse rate (ARR) (RR: 0.65, 95% CI: 0.43, 0.98). Final mean Expanded Disability Status Scale (EDSS) scores showed improvement from baseline (difference: -0.21, 95% confidence interval (CI): -0.34, -0.08). There was a significant decrease in gad-enhancing lesions during treatment (difference: -0.38, 95% CI: -0.64, -0.12). The mean score for the depression measure (21-item BDI-II questionnaire) significantly improved (difference: -2.39, 95% CI: -3.74, -1.03). There was a significant change in the "psychological well-being" dimension (P=0.02) (in line with BDI-II scores) and "rejection" MusiQoL dimensions (P=0.04). The adverse events documented throughout the study were not unexpected for GA and were principally not serious. CONCLUSION Safety measures were in line with the known profiles of GA. The results suggest that Cinnomer® is effective with respect to clinical outcomes and from the patient's perspective and in reducing MRI-measured MS activity.

Abstract
Earlier diagnosis, access to disease-modifying therapies (DMTs), and improved supportive care have favorably altered the disease course of multiple sclerosis (MS), leading to an improvement in long-term outcomes for people with MS (PwMS). This success has changed the medical characteristics of the population seen in MS clinics. Comorbidities and the accompanying polypharmacy, immune senescence, and the growing number of approved DMTs make selecting the optimal agent for an individual patient more challenging. Glatiramer acetate (GA), a moderately effective DMT, interacts only minimally with comorbidities, other medications, or immune senescence. We describe here several populations in which GA may represent a useful treatment option to overcome challenges due to advanced age or comorbidities (e.g., hepatic or renal disease, cancer). Further, we weigh GA's potential merits in other settings where PwMS and their neurologists must base treatment decisions on factors other than selecting the most effective DMT, e.g., family planning, conception and pregnancy, or the need for vaccination.

Abstract
Dysfunction of the immune system underlies a plethora of human diseases, requiring the development of immunomodulatory therapeutic intervention. To date, most strategies employed have been focusing on the modification of T lymphocytes, and although remarkable improvement has been obtained, results often fall short of the intended outcome. Recent cutting-edge technologies have highlighted macrophages as potential targets for disease control. Macrophages play central roles in development, homeostasis and host defence, and their dysfunction and dysregulation have been implicated in the onset and pathogenesis of multiple disorders including cancer, neurodegeneration, autoimmunity and metabolic diseases. Recent advancements have led to a greater understanding of macrophage origin, diversity and function, in both health and disease. Over the last few years, a variety of strategies targeting macrophages have been developed and these open new therapeutic opportunities. Here, we review the progress in macrophage reprogramming in various disorders and discuss the potential implications and challenges for macrophage-targeted approaches in human disease.

Comparison of Therapies in MS Patients After the First Demyelinating Event in Real Clinical Practice in the Czech Republic: Data From the National Registry ReMuS. Front Neurol 2021; 11:593527. [PMID: 33510704 PMCID: PMC7835499 DOI: 10.3389/fneur.2020.593527] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Accepted: 12/08/2020] [Indexed: 01/25/2023] Open
Abstract
Background: Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative disease of the central nervous system. Well-established drugs used for MS patients after the first demyelinating event in the Czech Republic include glatiramer acetate (GA), interferon beta-1a (IFNβ-1a), IFN beta-1b (IFNβ-1b), peginterferon beta-1a (peg-IFNβ-1a), and teriflunomide. Objective: The objective of this observational study was to compare the effectiveness of the abovementioned drugs in patients with MS who initiated their therapy after the first demyelinating event. Patients were followed for up to 2 years in real clinical practice in the Czech Republic. Methods: A total of 1,654 MS patients treated after the first demyelinating event and followed up for 2 years were enrolled. Evaluation parameters (endpoints) included the annualized relapse rate (ARR), time to next relapse, change in the Expanded Disability Status Scale (EDSS) score, and time of confirmed disease progression (CDP). When patients ended the therapy before the observational period, the reason for ending the therapy among different treatments was compared. Results: No significant difference was found among the groups of patients treated with IFNβ-1a/1b, GA, or teriflunomide for the following parameters: time to the first relapse, change in the EDSS score, and the proportion of patients with CDP. Compared to IFNβ-1a (44 mcg), a significant increase in the percentage of relapse-free patients was found for GA, but this treatment effect was not confirmed by the validation analysis. Compared to the other drugs, there was a significant difference in the reasons for terminating GA therapy. Conclusion: Small differences were found among GA, IFNβ and teriflunomide therapies, with no significant impact on the final outcome after 2 years. Therefore, in clinical practice, we recommend choosing the drug based on individual potential risk from long-term therapy and on patient preferences and clinical characteristics.

Rome BN, Tessema FA, Kesselheim AS. US Spending Associated With Transition From Daily to 3-Times-Weekly Glatiramer Acetate. JAMA Intern Med 2020; 180:1165-1172. [PMID: 32897384 PMCID: PMC7372513 DOI: 10.1001/jamainternmed.2020.2771] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/14/2022]
Abstract
IMPORTANCE Market exclusivity for daily injections of glatiramer acetate, a disease-modifying therapy for multiple sclerosis, expired in 2015. In 2014, the manufacturer launched an alternate 3-times-weekly version that was widely adopted, sustaining market dominance of brand-name glatiramer until late 2017. OBJECTIVE To estimate excess US spending associated with the transition from daily to 3-times-weekly glatiramer. DESIGN, SETTING, AND PARTICIPANTS This economic evaluation estimated total US glatiramer spending from January 1, 2011, to June 30, 2019, using a national cohort from 3 data sources that collectively represent approximately 40% of the US glatiramer market: Medicare Part D, Medicaid, and a claims database of commercially insured and Medicare Advantage patients. EXPOSURES Calendar quarter. MAIN OUTCOMES AND MEASURES Outcomes were quarterly US glatiramer spending, estimated as price × use. Manufacturer list prices for generic products and estimates of net (postrebate) prices for brand-name products were used. Linear regression and interrupted time series models were used to compare spending trends in 3 periods: before generic competition (2011-2015), during generic competition for daily glatiramer (2015-2017), and during generic competition for daily and 3-times-weekly glatiramer (2017-2019). RESULTS From 2011 to 2015, US glatiramer spending increased to $962 million per quarter and did not decrease with generic competition of only daily glatiramer (2015-2017). After generic competition began for 3-times-weekly glatiramer in 2017, prices decreased by 47% to 64%, and spending decreased to $508 million per quarter in 2019 (P < .001 for slope). The delay in decreased spending from 2015 to 2017 was associated with excess spending of $4.3 billion to $6.5 billion. CONCLUSIONS AND RELEVANCE These findings suggest that 2.5 years of delayed generic competition related to introduction of a new version of branded glatiramer acetate was associated with $4.3 billion to $6.5 billion in excess spending. Extended market exclusivity from introducing a new version of an existing brand-name drug can yield manufacturer returns out of proportion to the level of investment or risk involved; more limited incentives could encourage incremental innovations to existing drugs at a lower societal cost.

Efficacy and Safety of 2 Fingolimod Doses vs Glatiramer Acetate for the Treatment of Patients With Relapsing-Remitting Multiple Sclerosis: A Randomized Clinical Trial. JAMA Neurol 2020; 78:2769864. [PMID: 32852530 PMCID: PMC7445630 DOI: 10.1001/jamaneurol.2020.2950] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Accepted: 06/12/2020] [Indexed: 12/15/2022]
Abstract
IMPORTANCE Doses of fingolimod lower than 0.5 mg per day were not investigated during the fingolimod clinical development program. Whether lower doses of fingolimod might retain efficacy with fewer safety risks remains unknown. OBJECTIVE To evaluate the efficacy and safety of fingolimod, 0.5 mg, and fingolimod, 0.25 mg, compared with glatiramer acetate and to assess whether these doses of fingolimod show superior efficacy to glatiramer acetate in adult patients with relapsing-remitting multiple sclerosis. INTERVENTIONS Fingolimod, 0.5 mg, or fingolimod, 0.25 mg, orally once per day or glatiramer acetate, 20 mg, subcutaneously once per day. DESIGN, SETTING, AND PARTICIPANTS The Multiple Sclerosis Study Evaluating Safety and Efficacy of Two Doses of Fingolimod Versus Copaxone (ASSESS) was a phase 3b multicenter randomized rater-blinded and dose-blinded 12-month clinical trial conducted between August 9, 2012, and April 30, 2018 (including the time required to recruit participants). A total of 1461 patients aged 18 to 65 years with relapsing-remitting multiple sclerosis were screened, and 1064 participants were randomized. These participants had at least 1 documented relapse during the previous year or 2 documented relapses during the previous 2 years and an Expanded Disability Status Scale score of 0 to 6 at screening. Data were analyzed between September and November 2018. MAIN OUTCOMES AND MEASURES The superiority of the fingolimod doses was tested hierarchically, with fingolimod, 0.5 mg, vs glatiramer acetate, 20 mg, tested first, followed by fingolimod, 0.25 mg, vs glatiramer acetate, 20 mg. The primary end point was the reduction in annualized relapse rate (ARR). Magnetic resonance imaging parameters, safety, and tolerability were also assessed. RESULTS Of 1461 adult patients screened, 1064 participants (72.8%) were randomized (mean [SD] age, 39.6 [11.0] years; 792 women [74.4%]) to 3 treatment groups: 352 participants received fingolimod, 0.5 mg, 370 participants received fingolimod, 0.25 mg, and 342 participants received glatiramer acetate, 20 mg. In total, 859 participants (80.7%) completed the study. Treatment with fingolimod, 0.5 mg, was superior to treatment with glatiramer acetate, 20 mg, in reducing ARR (40.7% relative reduction); the relative reduction with fingolimod, 0.25 mg, was 14.6%, which was not statistically significant (for fingolimod, 0.5 mg, ARR, 0.15; 95% CI, 0.11-0.21; for fingolimod, 0.25 mg, ARR, 0.22; 95% CI, 0.17-0.29; for glatiramer acetate, 20 mg, ARR, 0.26; 95% CI, 0.20-0.34). Treatment with both fingolimod doses (0.5 mg and 0.25 mg) significantly reduced new or newly enlarging T2 and gadolinium-enhancing T1 lesions compared with treatment with glatiramer acetate. Adverse events were reported in similar proportions across treatment groups (312 participants [90.4%] in the fingolimod, 0.5 mg, group, 323 participants [88.3%] in the fingolimod, 0.25 mg, group, and 283 participants [87.3%] in the glatiramer acetate group). CONCLUSIONS AND RELEVANCE Fingolimod, 0.5 mg, demonstrated superior clinical efficacy compared with glatiramer acetate, 20 mg, and had a superior benefit-risk profile compared with fingolimod, 0.25 mg, in adult participants with relapsing-remitting multiple sclerosis.
