Caspofungin: new indication. No progress in invasive candidiasis.
(1) The reference treatment for invasive candidiasis in patients without neutropenia is standard amphotericin B. If this treatment fails or is too nephrotoxic, second-line alternatives are liposomal amphotericin B and fluconazole. Voriconazole is a third-line option. (2) Caspofungin, an antifungal drug belonging to the echinocandin class, is now approved for use in this indication in France. (3) The clinical evaluation dossier contains no data from comparative trials with fluconazole or voriconazole. It only gives the results of a double-blind trial in 239 patients, designed to show simply that caspofungin was not inferior to standard amphotericin B. Most of the patients did not have neutropenia. About one-third of the patients died. There was no difference in mortality between the two groups. No data are available from trials versus other forms of amphotericin B. (4) In this trial, caspofungin had fewer adverse effects (especially nephrotoxicity) than standard amphotericin B. However, in other trials in other indications, caspofungin had more adverse effects than fluconazole. (5) In France, caspofungin costs nearly 100 times more than standard amphotericin B. (6) In practice, caspofungin has no proven advantages over existing options for the treatment of invasive candidiasis in patients without neutropenia.
