Paroxysmal nocturnal hemoglobinuria (PNH) developed in a young man after an asymptomatic infection with SARS-CoV-2, the virus that causes COVID-19, a recent case study reports. The study, “Paroxysmal nocturnal hemoglobinuria in a patient post COVID-19 virus infection: A case report with literature review,” was published in…

Treatment with OMS906 is showing an ability to normalize all markers of red blood cell destruction, or hemolysis, in severely anemic people with paroxysmal nocturnal hemoglobinuria (PNH) never given a complement inhibitor. According to a five-month interim analysis of a Phase 1b proof-of-concept study (NCT05889299), once monthly, under-the-skin…

Monthly injections of the experimental therapy crovalimab controlled red blood cell loss and the need for blood transfusions for up to four years in adults with paroxysmal nocturnal hemoglobinuria (PNH), according to data from a long-term extension study. In fact, more than 80% — and up to 92% —…

A single dose of Homology Medicines’ gene therapy candidate HMI-104 led to the sustained production of a therapeutic antibody to treat paroxysmal nocturnal hemoglobinuria (PNH), preclinical studies suggest. “Given the severity of PNH, which is a rare, acquired blood disorder, and the unmet need associated with chronically administered…

European regulators have recommended approving Epysqli, a Soliris (eculizumab) biosimilar, to treat children and adults with paroxysmal nocturnal hemoglobinuria (PNH). The recommendation came from the Committee for Medicinal Products for Human Use (CHMP) and will serve as the basis for a final approval by the European Commission. Epysqli…

Most people with paroxysmal nocturnal hemoglobinuria (PNH) benefited from Soliris (eculizumab) therapy when they adhered to strict treatment guidelines, a real-world Dutch study showed. Because most had an incomplete response, new therapies are needed to improve real-world outcomes, however, the study’s researchers suggested, and emphasized that their data could…
