Background: Eculizumab, a humanized monoclonal antibody targeting the C5 complement protein, has been approved for the treatment of neuromyelitis optica spectrum disorders (NMOSD) in adult patients who are anti-aquaporin-4 (AQP4) antibody positive (Ab+). The aim of this study is to evaluate the long-term effectiveness and safety of eculizumab in French adults with NMOSD and to describe patients' characteristics, disability, and quality of life using data collected in a real-world setting.

Methods: This is the protocol for ECUP4, an ongoing prospective, observational, non-comparative, multicenter study conducted in 32 reference centers in France. Eligible patients must also be enrolled in NOMADMUS, a nested cohort of the French national multiple sclerosis registry (OFSEP). The primary endpoint is the annualized relapse rate. Secondary endpoints include the long-term safety of eculizumab, as well as patients' characteristics, treatment outcomes, disability, pain, visual acuity, and quality of life. Visits and treatments follow routine clinical practice. The case report forms (CRF) comprise data recorded in the context of the NOMADMUS cohort, collected during routine visits. The inclusion period is planned for 3 years, with no limitation on the number of patients enrolled. The maximum follow-up duration will be 5.5 years.

Conclusion: The efficacy and safety of eculizumab in patients with AQP4+ NMOSD have been demonstrated in randomized clinical trials that showed a significant reduction in the risk of relapse, with a safety profile consistent with other indications. This study will provide clinical and patient-reported evidence of the benefits of eculizumab, using data from a real-world setting in France.

Trial Registration Number: This study is registered at the French public repertory Health data Hub, N° F20211228123801. All information can be accessed at: https://www.health-data-hub.fr/.

Background: Thymoma-associated myasthenia gravis (TAMG) is a subtype of myasthenia gravis (MG) that is associated with more severe symptoms and a relatively poor prognosis. Eculizumab, an inhibitor to target human C5 component of the complement cascade, is considered a treatment option for refractory generalized MG (gMG).

Objectives: To explore the safety and efficacy of eculizumab in patients with TAMG.

Background: Thrombotic microangiopathy (TMA) is a rare, life-threatening disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage. Atypical hemolytic uremic syndrome (aHUS) is even less common, comprising less than 10% of hemolytic uremic syndrome (HUS) cases. aHUS in postpartum is associated with poor maternal outcomes, with the majority of cases resulting in end-stage renal disease.

Complement C5 inhibitor treatment with ravulizumab or eculizumab for paroxysmal nocturnal hemoglobinuria (PNH) improves outcomes and survival. Some patients remain anemic due to clinically significant extravascular hemolysis (cs-EVH: hemoglobin [Hgb] ≤9.5 g/dL and absolute reticulocyte count [ARC] ≥120×109/L).

Article Synopsis
  • * Results showed stable health markers (LDH, hemoglobin, reticulocytes) throughout the study, with no significant differences in kidney disease rates or need for blood transfusions among patients.
  • * The findings indicate that the biosimilar is both effective and safe for long-term use in PNH patients, with only a low incidence of adverse reactions reported.

Objectives: To evaluate the tolerability of crovalimab versus eculizumab in C5 inhibitor (C5i)-naive and -experienced patients with PNH from COMMODORE 2, 3 and 1 (NCT04434092, NCT04654468 and NCT04432584).

Methods: Pooled safety data were assessed in the total crovalimab and eculizumab populations and by C5i-naive versus C5i-switched status in patients receiving crovalimab. Analyses include 6.
