Mapping of C5‐Blocking Monoclonal Antibodies Reveals New C5 Inhibitory Epitopes and Novel Modes of C5 Inhibition

Immunology, EarlyView.
We identify four distinct C5 inhibitory epitopes, including two novel antibodies that selectively block membrane attack complex (MAC) assembly while preserving C5 cleavage and C5a generation. These findings establish selective MAC inhibition as a new therapeutic strategy for complement‐mediated diseases.

Breakthrough Hemolysis in Paroxysmal Nocturnal Hemoglobinuria: Mechanistic Insights and Management Strategies

Transfusion, EarlyView.
Abstract Background Paroxysmal nocturnal hemoglobinuria (PNH) is a clonal hematopoietic stem cell disorder caused by somatic mutations in the PIGA gene, resulting in loss of glycosylphosphatidylinositol (GPI)‐anchored proteins, including the complement regulatory proteins, CD55 and CD59.

Real‐world experience with eculizumab and switching to ravulizumab for generalized myasthenia gravis

Annals of Clinical and Translational Neurology
Objective Eculizumab and ravulizumab are complement protein C5 inhibitors, showing efficacy and tolerability for patients with anti‐acetylcholine receptor‐positive (AChR+) generalized myasthenia gravis (gMG) in phase 3 clinical trials and subsequent ...

High Proportion of PNH Type II Neutrophils Is Associated With Thrombosis in Patients Displaying a PNH Clone ≥ 1%

American Journal of Hematology, Volume 101, Issue 9, Page 2311-2328, September 2026.
ABSTRACT The clinical significance of PNH Type II white blood cells (WBCs) remains unclear. We assessed the relative percentage (rel%) of Type II neutrophils in 355 patients with a PNH clone ≥ 1% on neutrophils enrolled by 33 flow cytometry laboratories in the 5‐year French nation‐wide multicenter prospective observational study.

Cytokine‐Driven Hyperinflammation in Long COVID: Mechanisms, Biomarkers, Complement Dysregulation, and Emerging Immunotherapies—A Narrative Review

Health Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Long COVID, also known as post‐acute sequelae of SARS‐CoV‐2 infection (PASC), is a multisystem condition characterized by persistent symptoms that continue beyond the acute phase of infection. Growing evidence indicates that sustained immune dysregulation involving cytokine‐mediated inflammation, complement activation ...

Fatigue in Myasthenia Gravis: Recent Advances and Emerging Concepts

Muscle &Nerve, Volume 74, Issue S1, Page S24-S30, September 2026.
ABSTRACT Fatigue is a common, often disabling symptom in myasthenia gravis (MG), distinct from muscle fatigability, and strongly associated with reduced quality of life. This narrative review examines current evidence on fatigue in MG, its patient impact, and future research directions. Earlier studies, mostly small and heterogeneous, reported a highly

Lack of Differences in the Pharmacokinetics of Therapeutic Monoclonal Antibodies Between Japanese and Non‐Japanese Individuals

The Journal of Clinical Pharmacology, Volume 66, Issue 8, August 2026.
Abstract Evaluation of the pharmacokinetics (PK) of new drugs in Japanese individuals is regularly requested by the Japanese regulatory agency prior to participation in global clinical trials or for bridging approaches for regulatory approval. However, the need for PK assessments in the Japanese population may be less compelling for monoclonal ...

Myasthenia Gravis (MG) Resource Utilization, Epidemiology, Survival, and Treatment Patterns (MG‐REST): Estimating the Clinical and Economic Burden in Ontario, Canada

European Journal of Neurology, Volume 33, Issue 8, August 2026.
A cohort of patients living with myasthenia gravis (MG) in Ontario (n = 2601) were identified using health administrative data (2013–2020) to estimate burden of illness. MG prevalence increased from 36 to 42 per 100,000 over the study period. 5‐year survival was 75% overall and 39% among patients experiencing myasthenic crisis (8.9% of patients ...
