Oral Palmitoylethanolamide Treatment Is Associated with Reduced Cutaneous Adverse Effects of Interferon-?1a and Circulating Proinflammatory Cytokines in Relapsing-Remitting Multiple Sclerosis.

ABSTRACT: Palmitoylethanolamide (PEA) is an endogenous lipid mediator known to reduce pain and inflammation. However, only limited clinical studies have evaluated the effects of PEA in neuroinflammatory and neurodegenerative diseases. Multiple sclerosis (MS) is a chronic autoimmune and inflammatory disease of the central nervous system. Although subcutaneous administration of interferon (IFN)-?1a is approved as first-line therapy for the treatment of relapsing-remitting MS (RR-MS), its commonly reported adverse events (AEs) such as pain, myalgia, and erythema at the injection site, deeply affect the quality of life (QoL) of patients with MS. In this randomized, double-blind, placebo-controlled study, we tested the effect of ultramicronized PEA (um-PEA) added to IFN-?1a in the treatment of clinically defined RR-MS. The primary objectives were to estimate whether, with um-PEA treatment, patients with MS perceived an improvement in pain and a decrease of the erythema width at the IFN-?1a injection site in addition to an improvement in their QoL. The secondary objectives were to evaluate the effects of um-PEA on circulating interferon-?, tumor necrosis factor-?, and interleukin-17 serum levels, N-acylethanolamine plasma levels, Expanded Disability Status Scale (EDSS) progression, and safety and tolerability after 1 year of treatment. Patients with MS receiving um-PEA perceived an improvement in pain sensation without a reduction of the erythema at the injection site. A significant improvement in QoL was observed. No significant difference was reported in EDSS score, and um-PEA was well tolerated. We found a significant increase of palmitoylethanolamide, anandamide and oleoylethanolamide plasma levels, and a significant reduction of interferon-?, tumor necrosis factor-?, and interleukin-17 serum profile compared with the placebo group. Our results suggest that um-PEA may be considered as an appropriate add-on therapy for the treatment of IFN-?1a-related adverse effects in RR-MS.

Project description:IntroductionCutaneous adverse events (AEs) have been observed in clinical studies of daclizumab high-yield process (HYP) in relapsing-remitting multiple sclerosis (RRMS). Here, we report cutaneous AEs observed in the randomized, double-blind, active-comparator DECIDE study (ClinicalTrials.gov identifier, NCT01064401).MethodsDECIDE was a randomized, double-blind, active-controlled phase 3 study of daclizumab HYP 150 mg subcutaneous every 4 weeks versus interferon (IFN) beta-1a 30 mcg intramuscular (IM) once weekly in RRMS. Treatment-emergent AEs were classified and recorded by investigators. Investigators also assessed the severity of each AE, and whether it met the criteria for a serious AE. Cutaneous AEs were defined as AEs coded to the Medical Dictionary for Regulatory Activities System Organ Class of skin and subcutaneous tissue disorders. The incidence, severity, onset, resolution, and management of AEs were analyzed by treatment group.ResultsCutaneous AEs were reported in 37% of daclizumab HYP-treated patients and 19% of IFN beta-1a-treated patients. The most common investigator-reported cutaneous AEs with daclizumab HYP were rash (7%) and eczema (4%). Most patients with cutaneous AEs remained on treatment (daclizumab HYP, 81%; IM IFN beta-1a, 90%) and had events that were mild or moderate (94% and 98%) and subsequently resolved (78% and 82%). Most patients with cutaneous AEs did not require treatment with corticosteroids or were treated with topical corticosteroids (daclizumab HYP, 73%; IM IFN beta-1a, 81%). Serious cutaneous AEs were reported in 14 (2%) daclizumab HYP patients and one (<1%) IM IFN beta-1a patient.ConclusionThere was an increased risk of cutaneous AEs with daclizumab HYP. While physicians should be aware of the potential for serious cutaneous AEs, the typical cutaneous AEs were mild-to-moderate in severity, manageable, and resolved over time.FundingBiogen and AbbVie Biotherapeutics Inc.Trial registrationClinicalTrials.gov identifier, NCT01064401.

Project description:BACKGROUND: Numerous cytokines are implicated in the immunopathogenesis of multiple sclerosis (MS), but studies are often limited to whole blood (WB) or peripheral blood mononuclear cells (PBMCs), thereby omitting important information about the cellular origin of the cytokines. Knowledge about the relation between blood and cerebrospinal fluid (CSF) cell expression of cytokines and the cellular source of CSF cytokines is even more scarce. METHODS: We studied gene expression of a broad panel of cytokines in WB from relapsing-remitting multiple sclerosis (RRMS) patients in remission and healthy controls (HCs). Subsequently we determined the gene expression of the dysregulated cytokines in isolated PBMC subsets (CD4+, CD8+T-cells, NK-cells, B-cells, monocytes and dendritic cells) from RRMS patients and HCs and in CSF-cells from RRMS patients in clinical relapse and non-inflammatory neurological controls (NIND). RESULTS: RRMS patients had increased expression of IFN-gamma (IFNG), interleukin (IL) 1-beta (IL1B), IL7, IL10, IL12A, IL15, IL23, IL27, lymphotoxin-alpha (LTA) and lymphotoxin-beta (LTB) in WB. In PBMC subsets the main sources of pro-inflammatory cytokines were T- and B-cells, whereas monocytes were the most prominent source of immunoregulatory cytokines. In CSF-cells, RRMS patients had increased expression of IFNG and CD19 and decreased expression of IL10 and CD14 compared to NINDs. CD19 expression correlated with expression of IFNG, IL7, IL12A, IL15 and LTA whereas CD14 expression correlated with IL10 expression. CONCLUSIONS: Using a systematic approach, we show that expression of pro-inflammatory cytokines in peripheral blood primarily originates from T- and B-cells, with an important exception of IFNG which is most strongly expressed by NK-cells. In CSF-cell studies, B-cells appear to be enriched in RRMS and associated with expression of pro-inflammatory cytokines; contrarily, monocytes are relatively scarce in CSF from RRMS patients and are associated with IL10 expression. Thus, our findings suggest a pathogenetic role of B-cells and an immunoregulatory role of monocytes in RRMS.

Project description:Several treatments are currently available for relapsing-remitting multiple sclerosis. Among them, interferon (IFN) beta remains a valid treatment approach because of its good benefit/risk profile. Due to the need for frequent administration (weekly, at a minimum), the use of IFN beta is limited by uncomfortable side effects that could reduce adherence to and persistence with the treatment. The use of subcutaneous polyethylene glycol (PEG)ylated interferon beta-1a (PEG-IFN) has been proposed to offer a better combination of pharmacokinetic and pharmacodynamic profiles and therapy-related side effects. A 125 μg dose of PEG-IFN given every 2 or 4 weeks was tested in two Phase I studies and shown to be as safe and efficient as IFN beta-1a but with a longer half-life. A Phase III trial (ADVANCE) comparing 125 μg of PEG-IFN given every 2 or 4 weeks with placebo in 1,512 patients with relapsing-remitting multiple sclerosis showed significant reductions in both the annualized relapse rate (ARR) and the occurrence of new or newly enlarged T2 brain lesions in both experimental groups versus placebo after the first year. Moreover, 38% fewer patients showed progression of disability (P=0.04) in the PEG-IFN groups. During the second year, the ARR was further reduced in the PEG-IFN 2-week treatment group (0.230 at 1 year versus 0.178 at 2 years) and was maintained in the 4-week treatment group. Patients who received immediate PEG-IFN treatment showed improved clinical efficacy (ARR, risk of relapse, 12-week disability progression) and magnetic resonance imaging parameters (new T2 and newly enlarging lesions, gadolinium-positive lesions) compared with those with delayed treatment. The effects were more evident with the 2-week dose for all endpoints considered. Furthermore, PEG-IFN was well tolerated, and no new safety concerns arose. In conclusion, PEG-IFN has good efficacy and a good safety profile. The available data support the use of PEG-IFN as a suitable therapeutic option in patients with relapsing-remitting multiple sclerosis.

Project description:In Brazil, inclusion and exclusion of health technologies within the Unified Health System (SUS) is the responsibility of the National Committee for Health Technology Incorporation (CONITEC). A recent Cochrane systematic review demonstrated that intramuscular interferon beta 1a (IFN-?-1a-IM) was inferior to the other beta interferons (IFN-?s) for multiple sclerosis (MS). As a result, CONITEC commissioned an analysis to review possible disinvestment within SUS. The objective of this paper is to describe the disinvestment process for IFN-?-1a-IM in Brazil. The first assessment comprised a literature review and mixed treatment comparison meta-analysis. The outcome of interest was the proportion of relapse-free patients in 2 years. This analysis confirmed the inferiority of IFN-?-1a-IM. Following this, CONITEC recommended disinvestment, with the decision sent for public consultation. More than 3000 contributions were made on CONITEC's webpage, most of them against the preliminary decision. As a result, CONITEC commissioned a study to assess the effectiveness of IFN-?-1a-IM among Brazilian patients in routine clinical care. The second assessment involved an 11-year follow-up of a non-concurrent cohort of 12,154 MS patients developed by deterministic-probabilistic linkage of SUS administrative databases. The real-world assessment further demonstrated that IFN-?-1a-IM users had a statistically higher risk of treatment failure, defined as treatment switching or relapse treatment or death, with the assessment showing that IFN-?-1a-IM was inferior to the other IFN-?s and to glatiramer acetate in both direct and indirect analysis. In the drug ranking with 40,000 simulations, IFN-?-1a-IM was the worst option, with a success rate of only 152/40,000. Following this, CONITEC decided to exclude the intramuscular presentation of IFN-? from the current MS treatment guidelines, giving patients who are currently on this treatment the option of continuing until treatment failure. In conclusion, we believe this is the first example of this new disinvestment process in action, providing an exemplar for other treatments in Brazil as well as other countries.

Project description:BackgroundIn the pivotal phase III 2-year ADVANCE study, subcutaneous peginterferon beta-1a 125 mcg every 2 weeks demonstrated significant improvements in clinical outcomes, including disability endpoints, in patients with relapsing-remitting multiple sclerosis (RRMS). Here, we aim to further evaluate disability data from ADVANCE, and explore associations between confirmed disability progression (CDP), functional status, and health-related quality of life (HRQoL).MethodsIn total, 1512 patients were randomized to placebo or peginterferon beta-1a 125 mcg every 2 or 4 weeks. After 1 year, patients on placebo were re-randomized to peginterferon beta-1a every 2 or 4 weeks. CDP was defined as ⩾1.0 point increase from a baseline Expanded Disability Status Scale (EDSS) score ⩾ 1.0, or ⩾1.5-point increase from baseline 0, confirmed 12 or 24 weeks after onset.ResultsPeginterferon beta-1a every 2 weeks significantly reduced risk of 12- and 24-week CDP at 1 year compared with placebo (12-week CDP: 6.8% versus 10.5%, p = 0.038; 24-week CDP: 4% versus 8.4%, p = 0.0069, peginterferon beta-1a every 2 weeks versus placebo, respectively). Benefits were maintained over 2 years (11.2% and 7.7%, peginterferon beta-1a every 2 weeks in 12- and 24-week CDP, respectively). Approximately 90% of patients with 24-week CDP had simultaneous worsening by ⩾1 point in at least one functional system score, most commonly pyramidal. Displaying a 24-week CDP was associated with worse scores on the Multiple Sclerosis Functional Composite (MSFC) scale and several HRQoL instruments; the impact of CDP was attenuated by treatment with peginterferon beta-1a every 2 weeks.ConclusionsPeginterferon beta-1a has the potential to prevent/delay worsening of disability in patients with relapsing-remitting multiple sclerosis. Furthermore, improved benefits in disability status with peginterferon beta-1a were also associated with improved functional status and HRQoL [ClinicalTrials.gov identifier: NCT00906399].
