Introduction In clinical trials of alemtuzumab, autoimmune thyroid adverse events (AEs) were frequent. Here, we assess the impact of thyroid AEs on health-related quality of life (HRQL) in alemtuzumab-treated patients with relapsing-remitting multiple sclerosis (RRMS). Methods In phase 3 CARE-MS I (NCT00530348) and II (NCT00548405) trials, patients with RRMS were administered alemtuzumab 12 mg/day on 5 consecutive days at baseline and on 3 consecutive days 12 months later. Patients could participate in an extension study (NCT00930553) through year 6. HRQL was assessed at baseline and annually using the Functional Assessment of Multiple Sclerosis (FAMS), EuroQoL-5 Dimension Visual Analog Scale (EQ-5D VAS), and 36-Item Short-Form Survey (SF-36) questionnaires. Outcomes were analyzed in patients with or without thyroid AEs (nonserious or serious). A subset of patients with thyroid AEs was analyzed to assess HRQL before and during the onset of thyroid AEs. Results A total of 811 CARE-MS patients were treated with alemtuzumab. Of these, 342 (42%) patients experienced thyroid AEs over 6 years; serious thyroid AEs occurred in 44 (5%) patients. At year 6, HRQL outcomes generally remained slightly improved or similar to core study baseline in alemtuzumab-treated patients with or without thyroid AEs: FAMS (least-squares mean change from baseline without thyroid AEs, 0.7; with nonserious thyroid AEs, 5.1; with serious thyroid AEs, − 5.3), EQ-5D VAS (2.0; 3.0; − 6.8), SF-36 mental component summary (MCS [0.6; 1.6; − 2.8]), SF-36 physical component summary (PCS [0.8; 1.0; 1.1]). Over 6 years, 63–82% of patients in each group had improved/stable SF-36 MCS and PCS scores. Among patients with thyroid AE onset in year 3 (peak incidence), there were minimal differences between HRQL outcomes before onset (year 2) and after onset (year 3). Conclusion Autoimmune thyroid AEs (serious and nonserious) had minimal impact on HRQL in alemtuzumab-treated patients. These data may aid therapeutic decisions in patients with relapsing MS.

People who receive alemtuzumab may develop thyroid problems. The researchers wanted to know whether people who developed thyroid problems with alemtuzumab had a worse quality of life compared with those who did not. The researchers measured quality of life using a questionnaire. The questionnaire looked at people’s physical, social, and psychological well-being over 6 years. A total of 811 people with MS treated with alemtuzumab took part in this study. Of these, 469 people (58%) did not develop thyroid problems and 342 people (42%) developed thyroid problems. The thyroid problems were serious in 44 people. The researchers observed that thyroid problems during alemtuzumab treatment did not make quality of life worse in most people. Some people with serious thyroid problems had worsened quality of life; this was mostly among people who required certain treatments for their thyroid problems. Quality of life did not change much in people while the thyroid problems were ongoing. This study shows that thyroid problems after alemtuzumab treatment for MS have little negative impact on quality of life for most people. These findings may help healthcare providers make decisions about MS treatment.

Economic sustainability is of paramount importance in the rapidly evolving therapeutic scenario of multiple sclerosis (MS). Glatiramoids are a class of drugs whose forefather, glatiramer acetate, has been used as a disease modifying drug (DMD) in patients with MS for over 20 years. Its patent expired in 2015; new versions of such drug are nowadays available on the market, potentially contributing to lowering prices and enhancing a better allocation of economic resources. In this review, we analyze the recommendations underlying the approval of both generic drugs and biosimilars by regulatory authorities, and we provide methodological tools to contextualize the design of studies on these new classes of drugs. We examine in more detail the preclinical and clinical data of Copemyl®, a new member of the glatiramoid class, focusing on its biological and immunological properties and illustrating randomized controlled trials that led to its authorization.

Introduction Tumor necrosis factor-α (TNF-α) blocking agents may be associated with neurological adverse events, including demyelinating syndromes, that can be difficult to differentiate from multiple sclerosis (MS) and clinically isolated syndrome (CIS) as neither the clinical nor laboratory distinctive features have been reported. Usually clinicians mainly examine the diagnostic value of immunoglobulin G oligoclonal bands underestimating the value of other cerebrospinal fluid (CSF) parameters (such as CSF cytology). Case Report We present a case of a patient who acutely developed mild pyramidal and sensory impairment of lower limbs and urinary hesitancy during treatment with adalimumab, a monoclonal antibody to TNF-α, for psoriatic arthritis. Magnetic resonance imaging demonstrated a widespread area of hyperintense signal extending from C5 to D8 level in T2-weighted images. Two consecutive CSF examinations showed an intense activation of monocyte/macrophage lineage (88% and 90%, respectively) with some giant and binucleated cells that notably decreased five months after TNF-α blocker cessation. We compared the results of CSF examinations of our patient with CSF results of 20 patients with MS and 20 patients with CIS that demonstrated activation of both lymphocytic and monocytic lineage (MS: 48% and 52%, respectively, CIS: 54.5% and 43.5%, respectively) that were very different from the findings in adalimumab-related encephalomyelitis in acute phase (11% and 89%, respectively). CSF cytology in two patients with neuromyelitis optica during the relapse (n = 3) showed minor monocyte/macrophage activation (9%) and an increased number of granulocytes (77%). Conclusion Prominent activation of monocyte/macrophage lineage with some binucleated giant cells in CSF could be induced by anti-TNF-α treatment. The peculiar CSF pattern, never found in MS, CIS, and NMO, can help in differential diagnosis and stresses the importance of careful CSF cytology evaluation in the course of demyelinating diseases.

Introduction The choice of therapy in patients withdrawing from natalizumab treatment is still an open question and neurologists need strategies to manage this group of patients. The aim of this study is to evaluate if alemtuzumab is able to control the disease when used in patient who have stopped natalizumab. Methods 16 patients stopped natalizumab treatment after a median number of 20 infusions (range 12–114); all the patients were responders to natalizumab (neither clinical nor radiological activity during natalizumab therapy) and the reason for stopping was the risk of PML for all of them. Patients were switched to alemtuzumab after a median wash-out period of 70 days (range 41–99 days); patients underwent brain MRI every three months during natalizumab treatment and then just before starting alemtuzumab in order to exclude signs suggestive of PML; then, contrast-enhanced brain MRI was planned 6 and 12 months after alemtuzumab infusion. Results At present, 8 out of 16 patients have a follow-up >6 months and 2 out of 8 reached 1-year follow-up; 5 have a follow-up of 3–6 months and 3 have a follow-up
