Voydeya (danicopan) has been recommended for marketing authorisation in the European Union (EU) as an add-on to ravulizumab or eculizumab for the treatment of adult patients with paroxysmal nocturnal haemoglobinuria (PNH) who have residual haemolytic anaemia. Voydeya is a first-in-class, oral, Factor D inhibitor developed as an add-on to standard-of-care Ultomiris (ravulizumab) or Soliris (eculizumab) to address the needs of the approximately 10-20% of patients with PNH who experience clinically significant extravascular haemolysis (EVH) while treated with a C5 inhibitor.1,2
The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) based its positive opinion on results from the pivotal ALPHA Phase III trial. Results from the 12-week primary evaluation period of the trial were published in The Lancet Haematology.1
PNH is a rare and severe blood disorder characterised by the destruction of red blood cells within blood vessels, known as intravascular haemolysis (IVH), and white blood cell and platelet activation that can cause thrombosis (blood clots) and result in organ damage and potentially premature death.3-5 Immediate, complete and sustained terminal complement inhibition by blocking the C5 protein helps reduce symptoms and complications, resulting in improved survival for patients with PNH.5-8 Approximately 10-20% of people living with PNH who are treated with a C5 inhibitor experience clinically significant EVH, which can result in continued symptoms of anaemia and require blood transfusions.1-3,9-11
Professor Hubert Schrezenmeier, MD, Medical Director, Institute of Transfusion Medicine at The University of Ulm, said: “C5 inhibition with Ultomiris or Soliris is the standard-of-care in PNH, proven to control IVH and reduce life-threatening thrombotic events, yet a small portion of patients may experience clinically significant EVH. In the ALPHA trial, Voydeya as an add-on to Soliris or Ultomiris increased haemoglobin levels and reduced fatigue, anaemia and transfusion dependence. If approved, Voydeya may optimise care for people impacted by this burdensome condition while allowing patients to maintain disease control with an established C5 inhibitor.”
Marc Dunoyer, Chief Executive Officer, Alexion, said: “Today’s positive CHMP recommendation recognises the promise of Voydeya as an add-on to standard-of-care to address signs and symptoms of clinically significant EVH for this small subset of patients. As we saw in the pivotal ALPHA Phase III trial, dual complement pathway inhibition at Factor D and C5 may be an optimal treatment approach for these patients.”
