Abstract
Multiple sclerosis (MS) is a neurodegenerative condition of the central nervous system (CNS) that presents with varying levels of disability in patients, displaying the significance of timely and effective management of this complication. Though several treatments have been developed to protect nerves, comprehensive improvement of MS is still considered an essential bottleneck. Therefore, the development of innovative treatment methods for MS is one of the core research areas. In this regard, nanoscale platforms can offer practical and ideal approaches to the diagnosis and treatment of various diseases, especially immunological disorders such as MS, to improve the effectiveness of conventional therapies. It should be noted that there is significant progress in the development of neuroprotective strategies through the implementation of various nanoparticles, monoclonal antibodies, peptides, and aptamers. In this study, we summarize different particle systems as well as targeted therapies, such as antibodies, peptides, nucleic acids, and engineered cells for the treatment of MS, and discuss their potential in the treatment of MS in the preclinical and clinical stages. Future advances in targeted delivery of medical supplies may offer new strategies for complete recovery as well as practical treatment of progressive forms of MS.

Abstract
AIM To investigate clinical manifestations of multiple sclerosis (MS) and the genetic makeup of six affected members of one family. MATERIAL AND METHODS Six members of the family of Russian ethnic origin were examined. Pedigree analysis and genotyping of polymorphic markers of candidate genes for multiple sclerosis were performed. RESULTS AND CONCLUSION The accumulation of alleles that were associated with autoimmune diseases according to the results of genome-wide association studies (rs1109670*C, rs3129934*T, rs9523762*G, rs1570538*T) was found in the family. The results confirm the contribution of several genetic variants to familial forms of MS.

Abstract
OBJECTIVE This study aimed to present anthracenedione agents that have been used to treat multiple sclerosis (MS), problems related to their use, and knowledge gained from our experiences using these agents to develop more efficacious drugs with fewer adverse effects. METHODS We review preclinical and clinical data during the development mitoxantrone, an anthracycline, for the treatment of MS; benefits and potential risks; and strategies to reduce complications of anthracyclines. RESULTS Mitoxantrone had unacceptable and greater-than-anticipated toxicity for use in a chronic disease such as MS. Adverse effects included cardiotoxicity, treatment-associated leukemia, and amenorrhea. Toxicity was identified primarily in retrospect. Structurally related compounds include pixantrone (BBR2278) and BBR3378. Pixantrone is in clinical development in oncology. BBR3378 prevents the development of autoimmunity and experimental autoimmune encephalomyelitis and blocks experimental autoimmune encephalomyelitis even when given after the onset of autoimmunity. CONCLUSIONS There remains a need for effective MS treatment, particularly for nonrelapsing forms of MS. Mitoxantrone was the first nonbiologic drug approved by the Food and Drug Administration for use in MS. Chromophore modification of anthracenedione agents yielded a novel class of DNA binding agents (aza-anthracenediones such as pixantrone and aza-anthrapyrazoles such as BBR3378) with the potential for less cardiotoxicity compared with mitoxantrone. There is a need for long-term observation for delayed toxicity among humans enrolled in pixantrone trials. Preclinical toxicity studies for delayed toxicities in rodents and other models are warranted before consideration of derivatives of anthracenediones, aza-anthrazenediones, or aza-anthrapyrazoles for use in human MS clinical trials.

Abstract
BACKGROUND An antineoplastic agent, mitoxantrone (MX) is used to treat neurologic disability and/or reduce the frequency of clinical relapses in patients with secondary progressive, progressive relapsing, or worsening relapsing-remitting multiple sclerosis (MS). Based on a MEDLINE search for literature concerning the use of IV MX in patients with secondary progressive MS (SPMS), there is a paucity of data to identify the clinical characteristics of responders. OBJECTIVE The aim of this study was to monitor the effects of IV MX in patients with SPMS and varied clinical characteristics whose condition continued to worsen despite receiving IV methylprednisolone treatment. METHODS This prospective, open-label study was conducted at the Multiple Sclerosis Clinic, Center for Neurologic Disorders, Milwaukee, Wisconsin. Male and female patients aged ≥18 years with SPMS whose neurologic condition, as assessed using routine neurologic examination, worsened despite at least one 5-day course of IV methylprednisolone treatment (1 g/d) were enrolled. Patients received premedication with an antiemetic and IV MX 12 mg/m(2) every 12 weeks for up to 2 years, with a total cumulative dose not to exceed 96 mg/m(2). All patients were followed up for 1 year after treatment cessation. Efficacy was assessed at baseline, end of treatment, and 1-year follow-up using the Extended Disability Status Scale (EDSS) (which measures the functional disability level) (0 = normal findings on neurologic examination to 10 = death from MS complications). Tolerability was assessed before, during, and immediately after each infusion and at 2 weeks after each infusion, using direct questioning of, and spontaneous reporting by, the patients; physical examination; and laboratory assessments. Cardiac multigated acquisition scanning was performed at baseline and every 24 weeks during the treatment period. RESULTS Forty-eight patients were enrolled (28 women, 20 men; mean [SD] age, 47.6 [8.6] years; mean [SD] disease duration, 12.5 [6.0] years; mean [SD] baseline EDSS score, 6.9 [1.2]). Twenty-three patients completed the entire course of treatment; the remaining 25 were withdrawn after 1 year of treatment due to lack of efficacy (22 patients), asymptomatic cardiac ejection fraction <40% (2), and severe septicemia and worsening of MS requiring extended respiratory support and hospitalization (1). Patients who completed only 1 year of treatment were younger compared with those who completed 2 years (mean age, 45.2 vs 50.1 years; P < 0.05). No significant change in mean EDSS score was found at the end of treatment or at 1-year posttreatment follow-up. In patients whose disability improved by 2-0.5 on the EDSS (11 patients at 1 year; 5 patients at 2 years), the degree of improvement noted at 1-year follow-up in patients with a baseline EDSS score 3.0 to 5.5 versus 6.0 to 7.5 and 8.0 to 9.0 was significant (both, P < 0.05). Severe adverse effects occurred in 14.6% of patients and included marked leukopenia (peripheral white blood cell count, <100 cells/μL) with urosepsis, requiring hospitalization in 7 patients, 1 of whom developed severe septicemia and worsening of MS, requiring >4 weeks of respiratory support. Cardiac ejection fraction decreased to <40% in 2 patients after 1 year of treatment (total dose, 48 mg/m(2)). These 2 patients were asymptomatic, but the investigators decided to discontinue treatment. Cardiac function returned to normal range (but not to near-baseline levels) within 12 weeks after treatment cessation. Although all patients were premedicated with antiemetics, 10 (20.8%) reported mild nausea (treated with repeat administration of antiemetics), and 2 of 16 (12.5%) premenopausal patients reported slightly increased bleeding during menstruation after l year of IV MX therapy, requiring no medical therapy or adjustment in the treatment protocol. CONCLUSIONS Based on the results of this study in this small group of patients with worsening SPMS, IV MX treatment for up to 2 years was not associated with a significant change in EDSS score at the conclusion of treatment or 1 year after treatment cessation.

Abstract
Background Registry to Evaluate Novantrone Effects in Worsening Multiple Sclerosis (RENEW) was a 5-year, phase IV study in which the safety of Mitoxantrone was monitored in a patient cohort from the United States (US). The objective of the study was to evaluate the long-term safety profile of Mitoxantrone in patients with secondary progressive multiple sclerosis (SPMS), progressive relapsing multiple sclerosis (PRMS), and worsening relapsing-remitting multiple sclerosis (RRMS). Methods Overall, 509 patients (395 SPMS, 81 worsening RRMS, 33 PRMS) were enrolled and treated at 46 multiple sclerosis (MS) treatment centers located in the US. Patients received Mitoxantrone in accordance with the package insert every 3 months. During the treatment phase, patients received laboratory workups and cardiac monitoring every 3 months and then annually for a total of 5 years. Results Five hundred and nine subjects were enrolled in this trial and received at least one infusion of Mitoxantrone. Overall, 172 (33.8%) completed the 5-year trial (i.e., participated for 5 years ± 3 months [treatment + follow-up]); 337 (66.2%) did not complete the 5-year trial. Annual follow-up data were available for 250 of 509 enrolled patients. Left ventricular ejection fraction reduction under 50% was reported in 27 (5.3%) patients during the treatment phase (n = 509) and 14 (5.6%) patients during the annual follow-up phase (n = 250). Signs and symptoms of congestive heart failure were observed in 10 (2.0%) patients (six during treatment phase and four during the annual follow-up phase). Post-hoc analyses of the risk for cardiotoxicity outcomes revealed that cumulative dose exposure is the primary risk factor associated with the risk of cardiac toxicity with Mitoxantrone. Therapy-related leukemia was reported in three (0.6%) patients who received total cumulative Mitoxantrone doses of 73.5 mg/m2, 107.3 mg/m2, and 97.1 mg/m2 respectively. During the treatment phase, persistent amenorrhea developed in 22% (28/128) of women with regular menses and 51% (25/49) of women with irregular menses at baseline. During the annual follow-up phase, persistent amenorrhea developed in 5% (4/73) of women with regular menses at baseline. Conclusion RENEW results are consistent with the known safety profile of Mitoxantrone, and provide additional long-term safety data for Mitoxantrone in MS patients.

Abstract
BACKGROUND This is an updated Cochrane review of the previous published version.Mitoxantrone (MX) has been shown to be moderately effective in reducing the clinical outcome measures of disease activity in multiple sclerosis (MS) patients. OBJECTIVES The main objective was to assess the efficacy and safety of MX compared to a control group in relapsing-remitting (RRMS), progressive relapsing (PRMS) and secondary progressive (SPMS) MS participants. SEARCH METHODS We searched the Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Group Specialised Register (June 2012) and reference lists of articles. We also undertook handsearching and contacted trialists and pharmaceutical companies. SELECTION CRITERIA Randomised, double-blinded, controlled trials (RCTs) comparing the administration of MX versus placebo or MX plus steroids treatment versus placebo plus steroids treatment were included. DATA COLLECTION AND ANALYSIS The review authors independently selected articles for inclusion. They independently extracted clinical, safety and magnetic resonance imaging (MRI) data, resolving disagreements by discussion. Risk of bias was evaluated to assess the quality of the studies. Treatment effect was measured using odds ratios (OR) with 95% confidence intervals (CI) for the binary outcomes and mean differences (MD) with 95% CI for the continuous outcomes. If heterogeneity was absent, a fixed-effect model was used. MAIN RESULTS Three trials were selected and 221 participants were included in the analyses. MX reduced the progression of disability at two years follow-up (proportion of participants with six months confirmed progression of disability (OR 0.30, 95% CI 0.09 to 0.99 and MD -0.36, 95% CI- 0.70 to -0.02; P = 0.04)). Significant results were found regarding the reduction in annualised relapse rate (MD -0.85, 95% CI -1.47 to -0.23; P = 0.007), the proportion of patients free from relapses at one year (OR 7.13, 95% CI 2.06 to 24.61; P = 0.002) and two years (OR 2.82, 95% CI 1.54 to 5.19; P = 0.0008), and the number of patients with active MRI lesions at six months or one year only (OR 0.24, 95% CI 0.10 to 0.57; P = 0.001). Side effects reported in the trials (amenorrhoea, nausea and vomiting, alopecia and urinary tract infections) were more frequent in treated patients than in controls, while no major adverse events have been reported. These results should be considered with caution because of the heterogeneous characteristics of included trials in term of drug dosage, inclusion criteria and quality of included trials. Moreover, it was not possible to estimate the long-term efficacy and safety of MX. AUTHORS' CONCLUSIONS MX shows a significant but partial efficacy in reducing the risk of MS progression and the frequency of relapses in patients affected by worsening RRMS, PRMS and SPMS in the short-term follow-up (two years). No major neoplastic events or symptomatic cardiotoxicity related to MX have been reported; however studies with longer follow-up (not included in this review) have raised concerns about the risk of systolic disfunction (˜12%) and therapy-related acute leukaemias (0.8%), which are increasingly reported in the literature.MX should be limited to treating patients with worsening RRMS and SPMS and with evidence of persistent inflammatory activity after a careful assessment of the individual patients' risk and benefit profiles. Assessment should also consider the present availability of alternative therapies with less severe adverse events.

Abstract
OBJECTIVE The chemotherapeutic agent mitoxantrone was approved for use in multiple sclerosis (MS) in 2000. After a review of all the available evidence, the original report of the Therapeutics and Technology Assessment Subcommittee in 2003 concluded that mitoxantrone probably reduced clinical attack rates, MRI activity, and disease progression. Subsequent reports of decreased systolic function, heart failure, and leukemia prompted the US Food and Drug Administration to institute a "black box" warning in 2005. This review was undertaken to examine the available literature on the efficacy and safety of mitoxantrone use in patients with MS since the initial report. METHODS Relevant articles were obtained through a review of the medical literature and the strength of the available evidence was graded according to the American Academy of Neurology evidence classification scheme. RESULTS The accumulated Class III and IV evidence suggests an increased incidence of systolic dysfunction and therapy-related acute leukemia (TRAL) with mitoxantrone therapy. Systolic dysfunction occurs in approximately 12% of patients with MS treated with mitoxantrone, congestive heart failure occurs in approximately 0.4%, and leukemia occurs in approximately 0.8%. The number needed to harm is 8 for systolic dysfunction and 123 for TRAL. There is no new efficacy evidence that would change the recommendation from the previous report. CONCLUSIONS The risk of systolic dysfunction and leukemia in patients treated with mitoxantrone is higher than suggested at the time of the previous report, although comprehensive postmarketing surveillance data are lacking.

Abstract
The objective in this paper is to compare the cumulative incidence and incidence density of therapy-related acute myeloid leukaemia in two cohorts of patients with multiple sclerosis treated with mitoxantrone, and with previously reported data in the literature. Six new cases of acute myeloid leukaemia were observed by prospectively following two Spanish series of 142 and 88 patients with worsening relapsing multiple sclerosis and secondary-progressive disease treated with mitoxantrone. A literature review shows 32 further cases of acute myeloid leukaemia reported, 65.6% of which are therapy-related acute promyelocytic leukaemia. Five cases in the cohorts fulfilled the diagnostic criteria for acute promyelocytic leukaemia, and one patient was diagnosed with pre-B-acute lymphoblastic leukaemia. Acute myeloid leukaemia latency after mitoxantrone discontinuation was 1 to 45 months. The accumulated incidence and incidence density was 2.82% and 0.62%, respectively, in the Valencian cohort, and 2.27% and 0.44% in the Catalonian cohort. In the only seven previously reported series, the accumulated incidence varied from 0.15% to 0.80%. The real incidence of acute myeloid leukaemia after mitoxantrone therapy in the multiple sclerosis population could be higher as evidenced by the growing number of cases reported. Haematological monitoring should continue for at least 5 years after the last dose of mitoxantrone. These data stress the necessity of re-evaluating this risk.

Abstract
Mitoxantrone, the first immunosuppressant to receive FDA approval for treatment of worsening relapsing-remitting, secondary progressive, and progressive-relapsing multiple sclerosis (MS) is a DNA topoisomerase II inhibitor that has been associated with the development of acute promyelocytic myelogenous leukemia (APML). Central nervous system APML is a rare site of extramedullary involvement following mitoxantrone therapy. We report a patient with history of multiple sclerosis who developed bilateral optic nerve involvement as the primary manifestation of APML relapse following mitoxantrone treatment.

Abstract
Therapy-related acute promyelocytic leukemia (t-APL) with t(15;17) translocation is a well-recognized complication of cancer treatment with agents targeting topoisomerase II. However, cases are emerging after mitoxantrone therapy for multiple sclerosis (MS). Analysis of 12 cases of mitoxantrone-related t-APL in MS patients revealed an altered distribution of chromosome 15 breakpoints versus de novo APL, biased toward disruption within PML intron 6 (11 of 12, 92% vs 622 of 1022, 61%: P = .035). Despite this intron spanning approximately 1 kb, breakpoints in 5 mitoxantrone-treated patients fell within an 8-bp region (1482-9) corresponding to the "hotspot" previously reported in t-APL, complicating mitoxantrone-containing breast cancer therapy. Another shared breakpoint was identified within the approximately 17-kb RARA intron 2 involving 2 t-APL cases arising after mitoxantrone treatment for MS and breast cancer, respectively. Analysis of PML and RARA genomic breakpoints in functional assays in 4 cases, including the shared RARA intron 2 breakpoint at 14 446-49, confirmed each to be preferential sites of topoisomerase IIalpha-mediated DNA cleavage in the presence of mitoxantrone. This study further supports the presence of preferential sites of DNA damage induced by mitoxantrone in PML and RARA genes that may underlie the propensity to develop this subtype of leukemia after exposure to this agent.

Abstract
Mitoxantrone is a DNA-topoisomerase 2 inhibitor used as a single agent for treatment of relapsing-remitting or progressive multiple sclerosis (MS). We present here two patients treated with mitoxantrone for MS who subsequently developed acute promyelocytic leukemia (APL). These constitute, to our knowledge, the eighth and ninth reports of APL in patients treated with mitoxantrone for MS. Topoisomerase 2 inhibitors are associated with therapy-related acute myeloid leukemia (t-AML) with 11q23 abnormalities, but therapy-related APL (t-APL) is less common, and documentation of nine cases of t-APL after mitoxantrone therapy for MS suggests a specific association.

Abstract
Immunosuppressive agents have been used in multiple sclerosis (MS) for decades. The approval of several immunomodulatory agents against MS beginning in the 1990s, whose putative mechanisms of action appeared "more MS-specific," curtailed the importance of immunosuppressants, which made them treatment options of second choice. However, with the recent approval of mitoxantrone for treatment of patients with active forms of relapsing-remitting or secondary progressive MS and with a number of oral immunosuppressive agents being assessed in phase II and III clinical trials, a "renaissance" of this type of agents is currently occurring. This review provides an outline of the most important clinical studies and discusses relevant side effects of the major immunosuppressants (i.e., mitoxantrone, azathioprine, cyclophosphamide, methotrexate, mycophenolate mofetil, cladribine, and sirolimus/temsirolimus). The current knowledge of the putative mechanisms of action of these compounds is discussed.

Abstract
An important amount has been learnt about the mechanisms of action, efficacy and long-term toxicities of mitoxantrone. Importantly, recent observations strongly suggest that early administration of potent immunosuppressants (mitoxantrone and alemtuzumab) is definitely more effective than approved immunomodulators to delay or even reverse disability progression. Given the cardiotoxicity of mitoxantrone, restricting exposure to the drug to 2 or 3 years, the benefits and risks of immunosuppressants previously used as off-label treatments (cyclophosphamide and cladribine) have been revisited, and the potential efficacy in multiple sclerosis of recent immunosuppressants used in other autoimmune diseases, organ transplantation and cancer therapy has received increasing attention. Those immunosuppressants comprise monoclonal antibodies targeting B cells, lymphocytes and monocytes, IL-2 receptor and alpha4 integrin, as well as new molecules (pixantrone and isoxazole derivatives) and a new generation of immunosuppressants (fingolimod), which modulate lymphocyte re-circulation. This review addresses the most recent data concerning the efficacy and safety of mitoxantrone and of new experimental therapies that are presently in progress.

Abstract
BACKGROUND Mitoxantrone, an intravenously administered immunosuppressant that inhibits T-cell, B-cell, and macrophage proliferation, is indicated for reducing neurologic disability and relapse frequency in patients with secondary progressive multiple sclerosis (SPMS), progressive relapsing MS, or worsening relapsing-remitting MS (RRMS). OBJECTIVE This article reviews the pathogenesis and natural history of MS and examines the available treatment options for patients with RRMS, worsening RRMS, or SPMS, with a focus on mitoxantrone. METHODS MEDLINE (1966-present) and the Cochrane Central Register of Controlled Trials (1994-present) were searched for relevant randomized, blinded, controlled clinical trials using the terms mitoxantrone, Novantrone, and multiple sclerosis. RESULTS Five randomized, blinded, controlled trials and an ongoing open-label Phase IV safety study were identified and included in this review. In one randomized, double-blind trial (N=25), patients with RRMS who received mitoxantrone 8 mg/m2 monthly had significantly reduced relapse rates at 1 year compared with those who received placebo (P=0.014). In a 2-year, randomized, partially blinded trial (N=51), patients with active RRMS who received mitoxantrone 8 mg/m2 monthly had significantly fewer relapses compared with those who received placebo (P<0.001), and significantly fewer patients had confirmed progression of disability (1-point increase in Expanded Disability Status Scale [EDSS] score) (P=0.02). In a randomized, double-blind trial (N=49), patients with relapsing SPMS who received mitoxantrone 12 mg/m2 monthly for 3 months followed by 12 mg/m2 g3mo for up to 32 months had significant improvements in EDSS scores compared with those who received methylprednisolone 1 g IV monthly for 3 months followed by 1 g IV g3mo (P=0.002 at 1 year, P=0.045 at 2 years) and significant reductions in the number of gadolinium-enhancing lesions on magnetic resonance imaging (MRI) (P=0.002 at 1 and 2 years, P=0.03 at 3 years). In a randomized, partially blinded Phase II trial in 42 patients with active RRMS or SPMS, patients who received mitoxantrone 20 mg IV monthly and methylprednisolone 1 g IV monthly had significantly fewer new gadolinium-enhancing lesions on MRI (P<0.001) and significantly fewer relapses (P<0.01) at 6 months compared with those who received methylprednisolone alone. In a pivotal Phase III trial (N=194), patients with worsening RRMS or SPMS who received mitoxantrone 12 mg/m2 g3mo for 2 years had significantly fewer relapses (P<0.001) and significantly less deterioration in disability, as measured by change in EDSS score (P=0.019), compared with those who received placebo. In a nonrandomized subgroup of patients from this study (n=110), those who received mitoxantrone 12 mg/m2 g3mo had a significant reduction in the number of T2-weighted MRI lesions at 24 months (P=0.027). The most common adverse events in these studies included nausea and/or vomiting (18%-85%), alopecia (33%-61%), amenorrhea (8%-53%), urinary tract infections (6%-32%), and upper respiratory tract infections (4%-53%). Leukopenia was reported in 10% to 19% of patients. Use of mitoxantrone can lead to serious adverse effects, particularly cardiotoxicity, myelosuppression, and, rarely, leukemia. Long-term use of mitoxantrone may compromise left ventricular function. Limited cardiotoxicity was reported in the clinical studies; in the pivotal clinical trial, 2 patients who received mitoxantrone 12 mg/m2 had decreases in left ventricular ejection fraction to <50% of baseline. CONCLUSIONS In the available clinical trials, mitoxantrone provided effective treatment for worsening RRMS or SPMS. When mitoxantrone is used as recommended, the risks of substantial myelosuppressive and cardiotoxic effects can be reduced by careful patient selection, drug administration, and monitoring. The lifetime cumulative dose should be strictly limited to 140 mg/m2, or 2 to 3 years of therapy.

Abstract
INTRODUCTION On the basis of the French and British (FB) MS Trial, Mitoxantrone (MITOX) was approved by the AFSAPPS in October 2003 in patients with aggressive multiple sclerosis (MS), given as induction therapy monthly for 6 months (ELSEP). We report an observational study of 100 aggressive relapsing remitting (RR) MS patients treated by induction therapy with MITOX and followed up to 5 years. METHODS One hundred patients with aggressive RR MS received an induction therapy with MITOX 20 mg monthly combined with methylprednisolone 1 g for 6 months. MRI data within 12 months before and 6 months after MITOX induction were collected (mean cumulative dose 65 mg/m2). Clinical evaluation was performed every 6 months and data (relapses and EDSS scores) were prospectively recorded in the EDMUS Database. After MITOX, a maintenance therapy was given to 57 patients (MITOX every 3 months: 21; Interferon beta: 13; Azathioprine: 14; Methotrexate: 7; Glatiramer acetate: 2). The mean follow-up period was of 3.8 years. RESULTS Patients were treated at a mean age of 27 +/- 9 years after 5 +/- 3 years of MS duration. Within the 12 months preceding MITOX onset, the annual relapse rate (ARR) was 3.2, the mean EDSS increased by 2.2 +/- 1 points (to a score of 4 at M0), 87 patients worsened by 1 point EDSS or more and 85 percent of patients had Gd enhancing lesions on MRI. During the 12 months following MITOX onset, the inflammatory activity of the disease dropped dramatically with a reduction of the ARR by 91 percent whereas 76 percent of patients were free of new relapse and MRI activity was reduced by 89 percent. In addition, the mean EDSS decreased by 1.2 points (p<10-6) and 60 percent of patients improved by 1 point EDSS or more. At a longer term, the reduction of the ARR was confirmed (0.28-0.37 up to 5 years) and the median time to the first relapse was 2.8 years. A significant improvement of disability was maintained until 4 years and got back to the initial level at year 5. The ARR was significantly lower (0.09) for patients treated with MITOX every 3 months as maintenance therapy than for patients treated by other disease modifying therapies (0.33-0.39) or not (0.43) after the induction. Three patients presented an asymptomatic decrease of the left ventricular ejection fraction under 50 percent, reversible in one case. CONCLUSION MITOX as induction therapy monthly for 6 months was safe and had a rapid and strong impact on the inflammatory process and on the evolution of disability. The drug might be a good candidate as induction therapy followed by a maintenance therapy in patients with aggressive MS.

Abstract
INTRODUCTION Mitoxantrone (Mx) is used as a second-line treatment in multiple sclerosis. Since 1998, eight cases of acute leukemia (AL) have been described. We report two new cases of myeloid AL that occurred during treatment with Mx. OBSERVATIONS The first case concerned a women who was treated with Mx for 3 months. In spite of a very low total dose (58.32 mg), she developed promyelocytic AL. The second patient died of myeloid AL, 27 months after the last injection of Mx. DISCUSSION All the reported cases of AL occurring after Mx respond to the criteria of leukemia induced by anti-topoisomerases II. Epidemiological data and those from animal experiments suggest that Mx has direct role in the occurrence of leukemia. CONCLUSION It must be remembered that even if the risk of Mx-induced leukemia is low, blood cell counts must be closely monitored for at least five years after the last injection of this treatment.

Abstract
BACKGROUND Mitoxantrone (MX) has been shown to be moderately effective in reducing the clinical outcome measures of disease activity in multiple sclerosis (MS) patients. OBJECTIVES The objective was to assess the efficacy and safety of MX in relapsing-remitting MS (RRMS), progressive relapsing MS (PRMS) and secondary progressive MS (SPMS). SEARCH STRATEGY We searched the Cochrane MS Group Trials Register (searched April 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2004), MEDLINE (Pub Med) (January 1966 to April 2005), EMBASE (January 1974 to April 2005), and reference lists of articles. We also undertook hand searching and contacting trialists and pharmaceutical companies. SELECTION CRITERIA The trials were selected if double-blinded, placebo-controlled, randomised, irrespective of eventual additive therapy (such as steroids). DATA COLLECTION AND ANALYSIS Three reviewers independently selected articles for inclusion, assessed trials' quality and extracted data. MAIN RESULTS Four trials involving 270 participants were included. MX was found to reduce the progression of disability at 2 years follow-up (proportion of participants with 6-months confirmed progression of disability: Odds Ratios (OR) 0.3, p = 0.05). Similar figures were found regarding the reduction in annualised relapse rate and the proportion of patients free from relapses at 1 and 2 years, as well as the number of patients with active MRI lesions at 6 months/ 1 year only. Side effects reported in the trials were more frequent in treated patients than in controls. Caution must be exercised in drawing conclusions from such data because of the heterogeneous quality and characteristics of the included trials, which are different in terms of treatment schedule and type of enrolled patients. More than half of the included patients came from a single study. Moreover, from the included trials, it was not possible to estimate the long-term efficacy and safety of MX, which may raise concerns about the risk of cardiotoxicity and therapy-related leukemias, which is increasingly reported in the literature. AUTHORS' CONCLUSIONS MX is moderately effective in reducing the disease progression and the frequency of relapses in patients affected by RR, PR and SP MS in the short-term follow-up (2 years), even if the results are based on trials heterogeneous in terms of drug dosage and inclusion criteria. No major neoplastic or symptomatic cardiotoxicity related to MX have been reported from the trials. However, longer follow-up studies are highly warranted to better explore the efficacy and safety of the drug, mainly as regards the long-term risk of therapy-related leukemias and cardiotoxicity. As a conclusion, MX has a partial efficacy, but, due to its unclear long-term safety profile, it should be used to treat patients with worsening RR and SP MS with evidence of worsening disability.

Abstract
PURPOSE OF REVIEW This review focuses on novel aspects of the pathogenesis and advances in the therapy of multiple sclerosis (MS). RECENT FINDINGS Recent observations suggest that early lesion development in MS may start in some forms with oligodendrocyte death and that inflammation appears as a secondary phenomenon only. The lack of sufficient remyelination in MS may be the result of a disturbed function of basic helix-loop-helix transcription factors. Clinically the identification of patients with a clinically isolated syndrome at high risk to develop clinically definite MS remains difficult; the predictive value of serum antibodies against myelin proteins remains controversial. The role of neutralizing antibodies in interferon therapy is discussed. New therapeutic approaches in MS are emerging. SUMMARY The existing view on the pathogenesis of MS is still changing. The original assumption that cell-mediated demyelination is the key event in lesion development dictating clinical disability is critically reviewed and alternative pathways have been suggested. Oligodendrocyte death, axonal loss, the role of CD8 T lymphocytes, T regulatory cells, and B lymphocytes have come into the focus of newly evolving concepts in MS pathogenesis. A deepened understanding of the immunopathogenesis of this disease translates into innovative therapeutic approaches, such as blockade of alpha4 integrins by a humanized monoclonal antibody. In various animal models cell-replacement strategies yield promising results; however, turning these findings into an effective therapy in MS patients has a long way to go.

Abstract
Mitoxantrone (MX) is an immunosupressant drug used in secondarily progressive multiple sclerosis (SPMS) and in relapsing-remitting multiple sclerosis (RRMS). It has a leukemogenesis potential induced by cytogenetic abnormalities, though with a low incidence. Promyelocitic leukaemia (type M3) and other forms of acute myeloblastic leukaemias (M4 and M5) have been described in a few MS patients who received MX during their treatment. We describe a white female patient, 47 year-old, with SPMS (EDSS = 4) with 14 years of disease. She received MX during her disease and developed acute promyelocytic leukaemia (M3), with severe thrombocytopenia 30 months later. She ultimately died due to intracerebral hemorrhage. Other cases of treatment related to AML are reviewed and discussed.

Abstract
Several disease-modifying agents (DMAs) are approved for the treatment of multiple sclerosis, including three interferon (IFN)-beta products, glatiramer acetate and mitoxantrone. This article reviews the adverse event profiles of these DMAs based on the pivotal phase III trials, and provides practical guidelines for managing adverse effects. In general, the most common adverse events associated with IFN beta therapy are flu-like symptoms, including fever, chills and myalgias, and headache. The flu-like symptoms typically resolve within 24 hours and may be mitigated by over-the-counter anti-inflammatory agents. Adverse events related to glatiramer acetate therapy include injection-site reactions and a systemic reaction consisting of flushing, chest tightness, palpitation, anxiety or dyspnoea. The systemic reaction is transient (30 seconds to 30 minutes) and self-limited. Mitoxantrone may cause nausea, vomiting, alopecia, amenorrhoea and myelosuppression; isolated cases of acute leukaemia and dose-related cardiotoxicity have been reported in the literature. Longer-term tolerability data on mitoxantrone as a treatment for multiple sclerosis are needed. It is important for physicians to counsel patients on DMA-related adverse effects, most of which are transient and of mild-to-moderate severity. Various strategies that can be employed to prevent or manage these adverse effects and lessen their impact on the patient are discussed.

Abstract
As a rare complication of mitoxantrone (MITOX) therapy in multiple sclerosis (MS), a therapy-related acute leukaemia (TRAL) may develop. The incidence is difficult to estimate, as frequently single cases are reported, up to now a total of eight MS patients. Here we report a new case out of 644 patients. This is a 45-year-old female patient with secondary progressive MS who developed TRAL after a total dose of 48 mg/m2 MITOX. The TRAL was classified as acute myeloblastic leukaemia (AML) M4eo and showed an inversion of chromosome 16 and a partial trisomy 11. Her TRAL was treated with chemotherapy followed by allogeneic bone marrow transplantation. It responded well to the transplantation, whereas the MS symptoms initially worsened but have nearly returned to the pretransplantation level. This report brings the currently published frequency of MITOX-associated TRAL in MS therapy to five in a total of 2336 treated MS patients, representing an incidence of 0.21%.

Abstract
Mitoxantrone is a member of the anthracendione family developed to treat malignancies and increasingly used to treat multiple sclerosis (MS). It has been studied as a treatment for MS since the late 1980s, and is licensed in a number of countries for progressive and worsening MS. Review of the published earlier open-label, and more recently of controlled trials suggests that mitoxantrone is efficacious in cases of worsening MS that have an inflammatory component as evidenced by progression with or without superimposed relapses and/or gadolinium (Gd) enhancing magnetic resonance (MR) lesions. Today there is no robust evidence of efficacy in primary progressive MS or in later stages of secondary progressive MS beyond an EDSS score of 6. Relevant immunomodulatory mechanisms act both on T- and B-cell function, and mitoxantrone has selective immune effects in MS by decreasing levels of TNF-alpha, IL-2, IL-2R-beta1, IL-10 and IFN-gamma. Adverse events include nausea, alopecia, infections, menstrual disorders, risk of cardiotoxicity and malignancy. Different regimens are used according to different regulatory demands in different countries. The two most commonly used regimens are every 3 months intravenous (i.v.) 12 mg/m2 for 2 years or 20 mg mitoxantrone (i.v.) combined with 1 g methylprednisolone (i.v.) every 4 weeks for 6 months. The cumulative life dose in MS patients is 140 mg/m2. Mitoxantrone is currently used as a second line drug in MS patients whose disease is not controlled by beta-interferon or glatiramer acetate. In this review, we will discuss the clinical disease patterns of MS patients who are most likely to benefit from mitoxantrone, its magnitude of clinical effect, and limitations of using mitoxantrone in MS. Mitoxantrone as a second line therapy in non-responders of beta-interferon and glatiramer acetate will be assessed. Recent strategies of combination therapy, and the optimal dose regimen will also be discussed.

Abstract
The approval by the FDA of four immunomodulators (three IFNs and glatiramer acetate) and one immunosuppressant (mitoxantrone; Novantrone) for the treatment of multiple sclerosis is definitely the most important progress in this field since the first description of the disease > 150 years ago. However, both types of immunotherapies raise specific problems. Immunomodulators benefit patients in the relapsing-remitting phase, or patients in the secondary-progressive phase showing clinical and/or radiological signs of active inflammatory processes. Their benefit is modest, but seems to persist with long-term administration, as their tolerance is acceptable. Mitoxantrone is a rescue therapy reserved to patients with an aggressive, rapidly progressive form of the disease. This immunosuppressant is effective on inflammatory processes and pathomechanisms responsible for disability progression. Unfortunately, its cardiotoxicity and potential leukaemogenicity prevent an administration beyond 2 or 3 years. Thus, there is a need to improve on the efficacy of immunomodulators and to reduce the toxicity of immunosuppressants. Combination therapies with immunomodulators and antioxidants or with neuroprotective drugs against excitotoxicity or Na + /Ca 2+ channellopathy are currently being investigated. With regard to immunosuppressants, the development of monoclonal antibodies with fully human protein sequences and the synthesis of a new molecule as effective as mitoxantrone but with a much lower toxicity (pixantrone) seem promising to halt or even to prevent disability progression.
