Abstract

Rezafungin (Rezzayo™), an intravenous once-weekly echinocandin that inhibits 1,3-β-d-glucan synthase, is being developed by Cidara Therapeutics. In March 2023, rezafungin received approval in the USA for the treatment of candidaemia and invasive candidiasis in patients aged ≥ 18 years who have limited or no alternative treatment options. Rezafungin is also being developed for the prevention of invasive fungal diseases in blood and marrow transplant recipients. This article summarizes the milestones in the development of rezafungin leading to the first approval for the treatment of candidaemia and invasive candidiasis.
