AstraZeneca’s Voydeya (danicopan) has been approved in the U.S. as add-on therapy to ravulizumab or eculizumab for the treatment of extravascular haemolysis (EVH) in adults with paroxysmal nocturnal haemoglobinuria (PNH). 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 EVH while treated with a C5 inhibitor.
 
The FDA approval was based on positive results from the pivotal ALPHA Phase III trial that evaluated the efficacy and safety of Voydeya as add-on to Ultomiris or Soliris in patients with PNH who experienced clinically significant EVH. Results showed that Voydeya met the primary endpoint of change in haemoglobin from baseline to week 12 and all key secondary endpoints, including transfusion avoidance and change in Functional Assessment of Chronic Illness Therapy – Fatigue (FACIT-Fatigue) score.
 
Results from the ALPHA Phase III trial showed Voydeya was generally well tolerated, and no new safety concerns were identified. In the trial, the most common treatment-emergent adverse events were headache, nausea, arthralgia and diarrhoea.
 
Voydeya has been granted Breakthrough Therapy designation by the U.S. FDA and PRIority MEdicines (PRIME) status by the European Medicines Agency. Voydeya has also been granted Orphan Drug Designation in the U.S, EU and Japan for the treatment of PNH.
