Alemtuzumab: A Review in Relapsing Remitting Multiple Sclerosis
Drugs 2021 Jan;81(1):157-168.PMID:33367970DOI:10.1007/s40265-020-01437-2.
Alemtuzumab (Lemtrada®) is an anti-CD52 monoclonal antibody approved in the EU for the treatment of highly active relapsing-remitting multiple sclerosis (RRMS). In phase 3 trials in patients with active RRMS, intravenous Alemtuzumab was more effective than subcutaneous interferon β-1a in terms of decreasing relapse rates (in treatment-naïve or -experienced patients) and disability progression (treatment-experienced patients). Treatment benefits were maintained over up to 9 years of follow-up, with ≈ 50% of patients not requiring retreatment. The efficacy of Alemtuzumab in patients with highly active disease was generally similar to that in the overall population. Alemtuzumab has an acceptable tolerability profile, with infusion-associated reactions, infections and autoimmunity being the main safety and tolerability issues. Current evidence indicates that Alemtuzumab is an effective treatment option for adults with highly active RRMS, with an acceptable safety and tolerability profile and convenient treatment regimen.

Multiple sclerosis (MS) is a chronic, immune-mediated disease of the central nervous system comprising of inflammation, demyelinisation and neurodegeneration. The natural history of MS is heterogenous. Owing to the vast range and severity of the symptoms MS can cause the effect of the disease on one's cognitive and physical status is unpredictable. According to the new, phenotype based classification two subgroups can be distinguished; relapsing-remitting (RR) and progressive MS. Relapsing-remitting MS can be further divided into active and inactive disease. The activity of the disease can be proven either clinically and/or by radiological means. A patient's disease is considered inactive, if it fulfills the criteriae set in the "no evidence of disease activity-3" (NEDA-3) concept, meaning that no progression can be seen on the MRI scans, the patient is relapse free and there is no worsening on any disability scale. Nowadays a paradigm shift can be seen in the treatment of MS. The aim of this shift is to provide each and every patient with the most potent medication best suiting his/her illness as soon as possible. Alemtuzumab offers a great option as either a first line treatment or as escalation therapy for patients with a highly active disease. The efficacy of Alemtuzumab was proven in two phase III trials (CARE-MS I, II), where it was compared to subcutaneous interferon b-1a, administered three times weekly. In both studies Alemtuzumab was superior to subcutaneous interferon b-1a in terms of relapse rate reduction, in all scouted MRI parameters. In the CARE-MS II trial it was found superior in terms of progression slowing. In the studies' first 2 years 32% and 39% of the Alemtuzumab treated patients managed to achieve the NEDA-3 state (data from CARE-MS II and I respectively). At the end of the 4 year extension of both studies these numbers have increased to 60% and 55% respectively. The aim of our synopsis is to suggest neurologists an evidence based guideline, a therapeutic algorithm to be used when they give their MS patients the very best, personalised treatment, and also to appoint the recently introduced Alemtuzumab to its proper place in the algorithm.
Alemtuzumab in renal transplantation. Reviews of literature and usage in the United Kingdom
Transplant Rev (Orlando) 2022 Apr;36(2):100686.PMID:35151219DOI:10.1016/j.trre.2022.100686.
Kidney transplantation has evolved over the years from transplants between identically matched donors and recipients to successfully transplanting allografts across virtually any degree of donor-recipient human leukocyte antigen mismatch and ABO-incompatibility. Integral to these improved outcomes has been the development and deployment of a range of immunosuppressive agents. The addition of monoclonal and polyclonal antibodies as a standard part of overall immunosuppression has led to the improved outcomes by providing a robust and focused protection during the first few months of transplantation when allografts are most vulnerable to immune-mediated injury. Alemtuzumab is a recombinant anti-CD52 pan-lymphocyte depleting monoclonal antibody that has been in use for kidney transplantation since the late 1990s. Despite the many years of experience with Alemtuzumab, its utilisation in the UK has remained relatively restrained. This may be due to a lack of high-level evidence to support its safety and efficacy in transplantation. Also, long-term outcomes have not been addressed by existing studies. Nevertheless, available evidence suggests that Alemtuzumab is associated with a lower risk of acute rejection within the first year of transplantation while exhibiting a comparable safety profile to non-lymphocyte depleting agents. Despite the current economic advantages of Alemtuzumab (available free of cost on a named transplant recipient basis), its use in UK transplant centres has remained limited, variating from non-use, through usage in selected high immunologic risk subjects, to use as routine induction immunosuppression. This review discusses the current use of Alemtuzumab for immunosuppression induction in kidney transplantation. It describes its evolution from development to its present application in kidney transplantation and reviews the evidence underpinning its utilisation. The role of Alemtuzumab in the immunosuppressive protocols individual UK kidney transplant centres is also described.
Alemtuzumab for the treatment of multiple sclerosis
Expert Opin Biol Ther 2018 Mar;18(3):323-334.PMID:29309202DOI:10.1080/14712598.2018.1425388.
Alemtuzumab is a monoclonal antibody that targets for the destruction CD52+ cells, particularly B and T cells. Alemtuzumab is approved in more than 50 countries around the world for the treatment of adult patients with relapsing remitting multiple sclerosis (MS). Areas covered: In this review, the authors summarize biological, clinical and safety data related to the use of Alemtuzumab in patients with MS. The authors then provide their expert opinion on Alemtuzumab and the field as of whole before providing their perspectives for the future. Expert opinion: Alemtuzumab is highly efficacious; more so than first line treatments but comparable to natalizumab. Treatment schedule makes Alemtuzumab administration easy and attractive to patients. However, its safety profile makes it a choice for a very limited number of patients, in a specific disease window. As of now, a cure for MS remains elusive and there is an unmet need for a safe and highly potent agent at the level of and beyond the blood brain barrier.
Alemtuzumab for refractory primary systemic vasculitis-a randomised controlled dose ranging clinical trial of efficacy and safety (ALEVIATE)
Arthritis Res Ther 2022 Apr 1;24(1):81.PMID:35365179DOI:10.1186/s13075-022-02761-6.
Background: Primary systemic vasculitis (PSV) is a heterogeneous group of autoimmune conditions. There is an unmet need for alternative therapies that lead to sustained remission in patients with refractory disease. Alemtuzumab, an anti-CD52 antibody, depletes lymphocytes for prolonged periods and, in retrospective studies, has induced sustained, treatment-free remissions in patients with refractory/relapsing vasculitis but has raised safety concerns of infection and secondary autoimmunity. This phase IIb clinical trial aimed to assess the efficacy and safety of Alemtuzumab, at two different doses, in inducing remission in refractory vasculitis patients. Methods: The ALEVIATE trial was a randomised, prospective, open-label, dose ranging clinical trial. Patients with refractory ANCA-associated vasculitis (AAV) or Behçet's disease (BD) were randomised to receive either 60 mg or 30 mg Alemtuzumab. Treatments were administered at baseline and 6 months or earlier where clinically appropriate. A maximum of three treatments were allowed within the 12-month study period. Results: Twenty-three patients received at least one dose of Alemtuzumab. Twelve had AAV, and 11 a diagnosis of BD. The median age was 40 years (range 28-44), with a prior disease duration of 61 months (42-103). Sixteen (70%) achieved either complete (6/23, 26%) or partial (10/23, 44%) response at 6 months. Eight (35%) maintained remission to the end of the trial without relapse. Ten severe adverse events were observed in 7 (30%) patients; 4 were related to Alemtuzumab. There were no differences in clinical endpoints between the 60 and 30 mg Alemtuzumab treatment groups. Conclusion: In a selected group of refractory vasculitis patients, Alemtuzumab led to remission in two thirds of patients at 6 months. Remission was maintained to 12 months in a third of the patients, and the safety profile was acceptable.
