Article Synopsis
  • Paroxysmal nocturnal hemoglobinuria (PNH) causes intravascular hemolysis due to a lack of complement regulation, leading to symptoms like anemia, pain, and fatigue, but can be treated with complement inhibitors to reduce disease-related complications and mortality.
  • Eculizumab and ravulizumab, terminal complement inhibitors, improve survival rates, but many patients still experience issues from extravascular hemolysis, necessitating new treatment options.
  • Proximal complement inhibitors (like pegcetacoplan, danicopan, and iptacopan) can help normalize hemoglobin levels and enhance quality of life for patients with significant extravascular hemolysis, though a clear treatment algorithm for choosing among

Article Synopsis
  • Paroxysmal nocturnal hemoglobinuria (PNH) is a rare blood disorder caused by a mutation in hematopoietic stem cells that leads to a lack of protective proteins on red blood cells, making them vulnerable to destruction.
  • The resulting symptoms include anemia, fatigue, and increased risk of blood clots due to complement-mediated hemolysis.
  • Current treatments focus on inhibiting different stages of the complement activation pathway to manage symptoms and enhance patient outcomes, with pegcetacoplan being highlighted as a notable C3-targeted therapy.
