The cases of three people with paroxysmal nocturnal hemoglobinuria (PNH) who experienced serious complications after switching from an experimental medicine to the approved PNH treatment Ultomiris (ravulizumab) highlight the potential for serious risks when switching from a PNH treatment targeting earlier steps of complement activation to one targeting…

Health Canada has approved the oral therapy Voydeya (danicopan) as an add-on to Ultomiris (ravulizumab) or Soliris (eculizumab) in adults with paroxysmal nocturnal hemoglobinuria (PNH) who have residual anemia due to blood cell destruction taking place outside blood vessels. The announcement came just a few months…

The U.S. Food and Drug Administration (FDA) has approved crovalimab — which works to reduce the destruction of red blood cells in paroxysmal nocturnal hemoglobinuria (PNH) — to treat teenagers and adults with PNH. The therapy, which won formal approval from the FDA on June 20, is…

Soliris (eculizumab) was successfully used to help manage paroxysmal nocturnal hemoglobinuria (PNH) during a pregnancy in two women.

The oral therapy Voydeya (danicopan) is now approved in the European Union as an add-on treatment for paroxysmal nocturnal hemoglobinuria (PNH). The European Commission authorized the therapy for adults with PNH who have residual hemolytic anemia — that is, low counts of red blood cells because those…

Treatment with Soliris (eculizumab) or Ultomiris (ravulizumab) can substantially reduce the likelihood of death as a direct result of paroxysmal nocturnal hemoglobinuria (PNH), a new study found. While the findings showed that PNH itself is rarely fatal for people taking these therapies, co-occurring bone marrow failure remains…

The U.S. Food and Drug Administration (FDA) has approved Voydeya (danicopan) as an add-on treatment for extravascular hemolysis, or the destruction of red blood cells taking place outside blood vessels, in adults with paroxysmal nocturnal hemoglobinuria (PNH). The treatment is to be taken with the standard-of-care therapies Ultomiris…

A European Medicines Agency committee has recommended that Novartis’ twice-daily oral therapy Fabhalta (iptacopan) be approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH). The recommendation from the Committee for Medicinal Products for Human Use (CHMP) supports Fabhalta’s use as a monotherapy, or stand-alone treatment, in adults with…

The U.S. Food and Drug Administration (FDA) has granted orphan drug status to ruxoprubart, an experimental treatment for paroxysmal nocturnal hemoglobinuria (PNH) that’s now in Phase 2 clinical testing. The drug is designed to control the genetic disease while posing a lower infection risk than currently available treatments. Orphan…

Danicopan has been approved in Japan as a first-in-class, add-on therapy for people with paroxysmal nocturnal hemoglobinuria (PNH) who have an insufficient response to treatment with C5 inhibitors.
