Real-world analysis supports effectiveness, safety of Ultomiris

When used in real-world practice to treat paroxysmal nocturnal hemoglobinuria (PNH), the safety and effectiveness of Ultomiris (ravulizumab-cwvz) is similar to what’s been reported in clinical trials, according to a recent study from Japan. “These real-world data support the safety and effectiveness of [Ultomiris] treatment in Japanese patients,”…

Zilucoplan reduces blood cell destruction in untreated PNH

Treatment with the experimental medication zilucoplan reduced blood cell destruction in previously untreated people with paroxysmal nocturnal hemoglobinuria (PNH) in Phase 2 clinical trials. However, PNH patients who switched to zilucoplan from an approved PNH therapy experienced more blood cell destruction, results showed. That’s according to findings detailed…

Crovalimab protects red blood cells, eases fatigue of PNH in Phase 3 trial

Treatment with crovalimab, an experimental under-the-skin injection therapy, effectively prevented red blood cell death, reduced the need for blood transfusions, and eased fatigue in adults and adolescents with paroxysmal nocturnal hemoglobinuria (PNH). That’s according to a primary analysis of data from the Phase 3 COMMODORE 3 trial (NCT04654468),…

Omoprubart heading to pivotal stage of testing

Treatment with the experimental complement-blocking therapy omoprubart reduced markers of hemolysis, or blood cell destruction, in people with paroxysmal nocturnal hemoglobinuria (PNH). Those findings, from preliminary data of a Phase 1/2 study, were announced by its developer, China-based Canbridge Pharmaceuticals, which now is planning to launch a pivotal…

Experimental treatment NM3086 seems to work as designed: Study

NM3086, an experimental therapy for paroxysmal nocturnal hemoglobinuria (PNH) that’s designed to block the alternative complement pathway’s activation, was generally well tolerated in a first in-human clinical trial. Findings from the Phase 1 study with healthy volunteers suggest NM3086 is working as intended, according to its developer, NovelMed.

Treating common infections early may be life-saving in PNH: Report

Varicella-zoster virus — which causes chickenpox and shingles — can lead to fatal infections in people with paroxysmal nocturnal hemoglobinuria (PNH) who are on immune-suppressing treatment, a case report highlights. Researchers urge clinicians to be aware of signs of possible infection in a report, “Disseminated varicella-zoster…

Bone marrow transplant may be effective for PNH after, with cancer

A bone marrow transplant may be an effective treatment for some people with bone marrow cancer who develop subsequent or co-occurring paroxysmal nocturnal hemoglobinuria (PNH), a study indicates. The study, “Haemolytic paroxysmal nocturnal haemoglobinuria in patients with myeloid neoplasms: A rare association with specific therapeutic implications,”…
