Abstract
BACKGROUND The reason why some multiple sclerosis (MS) patients show disease activity after alemtuzumab (ALM) is still unclear, but ocrelizumab (OCR) could represent an interesting sequential therapeutic approach. OBJECTIVES To investigate safety and efficacy of OCR in MS patients with disease activity after two ALM courses. METHODS Observational retrospective multi-centers Italian cohort study. RESULTS Seventy-two subjects were included. Mean follow-up (FU) was 2.4 (±1) years. Forty-five patients (62.5%) experienced at least one adverse event (AE), with infections accounting for 96.7% of cases. A reduction in total lymphocytes was observed between OCR start and 6 months FU, driven by BCD19+ lymphocytes depletion (p < 0.001). Immunoglobulin M (IgM) levels decreased between OCR start and 6 months FU (p < 0.001). At 2-year FU, relapse, magnetic resonance imaging (MRI) activity and disability worsening-free survival were 92.1%, 90.8%, and 89.2%. The evidence of inflammatory activity between the two ALM courses was associated with higher risk of relapse, MRI activity, and NEDA-3 status loss in relapsing-remitting multiple sclerosis (RRMS; p = 0.02, p = 0.05, p = 0.01, respectively). CONCLUSIONS OCR after two ALM courses seemed to be safe and effective. Early IgM hypogammaglobulinemia occurred in a high proportion of patients. The evidence of inflammatory activity between ALM courses seemed to increase the risk of MS re-activation on OCR treatment.

Abstract
OBJECTIVE Asthma is a major global disease affecting adults and children, which can lead to hospitalization and death due to breathing difficulties. Although targeted monoclonal antibody therapies have revolutionized treatment of severe asthma, some patients still fail to respond. Here we critically evaluate the literature on biologic therapy failure in asthma patients with particular reference to anti-drug antibody production, and subsequent loss of response, as the potential primary cause of drug failure in asthma patients. RECENT FINDINGS Encouragingly, asthma in most cases responds to treatment, including the use of an increasing number of biologic drugs in moderate to severe disease. This includes monoclonal antibody inhibitors of immunoglobulin E and cytokines, including interleukin 4, 5, or 13 and thymic stromal lymphopoietin. These limit mast cell and eosinophil activity that cause the symptomatic small airways obstruction and exacerbations. SUMMARY Despite humanization of the antibodies, it is evident that benralizumab; dupilumab; mepolizumab; omalizumab; reslizumab and tezepelumab all induce anti-drug antibodies to some extent. These can contribute to adverse events including infusion reactions, serum sickness, anaphylaxis and potentially disease activity due to loss of therapeutic function. Monitoring anti-drug antibodies (ADA) may allow prediction of future treatment-failure in some individuals allowing treatment cessation and switching therefore potentially limiting disease breakthrough.

Abstract
The landscape of immunotherapies in the management of Multiple Sclerosis (MS) is currently particularly dynamic. Over 21 immunotherapeutic options are approved by the European Meidcines Agency (EMA), Food and Drug Administration (FDA) and newer approaches are ongoing in clinical trials. With advancements in the understanding of MS pathophysiology and further development of diagnosis criteria, newer and more specific disease-modifying therapies (DMTs) have emerged in recent years. The selection and timing of proper therapeutic approaches is increasingly complex. We provide an overview of the available immunotherapies for a personalized MS treatment and discuss practical insights into their application. The importance of early intervention, distinction between escalation and induction approaches, and consideration of high-efficacy treatments for specific patient groups are in discussed. We emphasize the significance of a patient-centered approach, taking into account various factors such as comorbidities, family planning, administration preferences and potential side effects in treatment decision-making.

Abstract
ABSTRACT Alemtuzumab is a humanized anti-CD52 antibody that is registered for treatment of highly active relapsing-remitting multiple sclerosis. Disease activity after alemtuzumab treatment is infrequent. It may be a result of lack of lymphocyte depletion due to development of neutralizing autoantibodies. On the other hand, severe disease activity has been described after alemtuzumab, which is suggested to be caused by B-cell hyperpopulation. We present a case of a person with multiple sclerosis with severe disease activation after alemtuzumab administration that may represent paradoxical B cell-mediated disease activity. The patient was successfully treated with ocrelizumab.

Abstract
The development of antidrug antibodies (ADAs) is a major problem in several recombinant protein therapies used in the treatment of multiple sclerosis (MS). The etiology of ADAs is multifaceted. The predisposition for a breakdown of immune tolerance is probably genetically determined, and many factors may contribute to the immunogenicity, including structural properties, formation of aggregates, and presence of contaminants and impurities from the industrial manufacturing process. ADAs may have a neutralizing capacity and can reduce or abrogate the bioactivity and therapeutic efficacy of the drug and cause safety issues. Interferon (IFN)-β was the first drug approved for the treatment of MS, and-although it is generally recognized that neutralizing antibodies (NAbs) appear and potentially have a negative effect on therapeutic efficacy-the use of routine measurements of NAbs and the interpretation of the presence of NAbs has been debated at length. NAbs appear after 9-18 months of therapy in up to 40% of patients treated with IFNβ, and the frequency and titers of NAbs depend on the IFNβ preparation. Although all pivotal clinical trials of approved IFNβ products in MS exhibited a detrimental effect of NAbs after prolonged therapy, some subsequent studies did not observe clinical effects from NAbs, which led to the claim that NAbs did not matter. However, it is now largely agreed that persistently high titers of NAbs indicate an abrogation of the biological response and, hence, an absence of therapeutic efficacy, and this observation should lead to a change of therapy. Low and medium titers are ambiguous, and treatment decisions should be guided by determination of in vivo messenger RNA myxovirus resistance protein A induction after IFNβ administration and clinical disease activity. During treatment with glatiramer acetate, ADAs occur frequently but do not appear to adversely affect treatment efficacy or result in adverse events. ADAs occur in approximately 5% of patients treated with natalizumab within 6 months of therapy, and persistent NAbs are associated with a lack of efficacy and acute infusion-related reactions and should instigate a change of therapy. When using the anti-CD20 monoclonal antibodies ocrelizumab and ofatumumab in the treatment of MS, it is not necessary to test for NAbs as these occur very infrequently. Alemtuzumab is immunogenic, but routine measurements of ADAs are not recommended as the antibodies in the pivotal 2-year trials at the population level did not influence lymphocyte depletion or repopulation, efficacy, or safety. However, in some individuals, NAbs led to poor lymphocyte depletion.

Abstract
BACKGROUND AND PURPOSE Alemtuzumab, a monoclonal anti-CD52 antibody, and cladribine, a purine nucleoside analogue, are used for the treatment of highly active relapsing-remitting multiple sclerosis (MS). Both are administered as two short yearly courses but possess the ability to induce long-term remission, labeling them as immune reconstitution therapies. Although disease activity after alemtuzumab administration is rare, there are a small number of people with MS who will experience disease activity despite repeated alemtuzumab treatment. METHODS We report on six patients with MS who experienced disease activity after alemtuzumab and were subsequently treated with cladribine and followed up for up to 2 years. RESULTS None of the patients experienced relapses during the follow-up period and in all patients Expanded Disability Status Scale values remained unchanged. All patients had lymphopenia at one time point. In patients 1 and 2, at the nadir, the lymphopenia was grade 1, in patient 3 it was grade 2 and in patients 5 and 6 it was grade 3. No infections or malignancies were recorded during the follow-up. CONCLUSION This report provides a framework for treating people with MS with sequential immune reconstitution therapies.

Abstract
Multiple sclerosis is the major demyelinating autoimmune disease of the central nervous system. Relapsing MS can be treated by a number of approved monoclonal antibodies that currently target: CD20, CD25 (withdrawn), CD49d and CD52. These all target potentially pathogenic memory B cell subsets and perhaps functionally inhibit pathogenic T cell function. These consist of chimeric, humanized and fully human antibodies. However, despite humanization it is evident that all of these monoclonal antibodies can induce binding and neutralizing antibodies ranging from < 1% to over 80% within a year of treatment. Importantly, it is evident that monitoring these allow prediction of future treatment-failure in some individuals and treatment cessation and switching therefore potentially limiting disease breakthrough and disability accumulation. In response to the COVID-19 pandemic and the need to avoid hospitals, shortened infusion times and extended dose intervals have been implemented, importantly, subcutaneous delivery of alternative treatments or formulations have been developed to allow for home treatment. Therefore, hospital-based and remote monitoring of ADA could therefore be advantageous to optimize patient responses in the future.

Abstract
The number of biologic drugs available for the treatment of psoriasis continue to expand. However, being biological proteins and thus potentially immunogenic, there is evidence that anti-drug-antibodies develop against the various therapeutic proteins currently being utilised. Although chimeric antibodies that contain elements of the parental rodent monoclonal antibodies are immunogenic, anti-drug antibodies occur even if the biologic is a fully human protein and these can impact on clinical efficacy and safety. However, there is a wide variation in the reported level of anti-drug-antibodies for the same and different treatments that is highlighting issues with various assays used in anti-drug antibody detection. Here we review the available data on the occurrence of anti-drug antibodies in people with psoriasis treated with biologic agents.
