Second-line therapy with caspofungin for mucosal or invasive candidiasis: results from the caspofungin...

To prospectively assess the efficacy and safety of caspofungin as second-line therapy for mucosal or invasive candidiasis in patients enrolled in the caspofungin compassionate-use study.

Thirty-seven patients with mucosal or invasive candida infections (17 oesophageal, four oropharyngeal and 16 invasive candidiasis) were enrolled in the caspofungin compassionate-use study. All patients were refractory to or intolerant of intravenous amphotericin B or lipid amphotericin formulation(s). Efficacy was assessed at the end of intravenous caspofungin therapy based on clinical (and, where appropriate, microbiological) response.

HIV was the most common (91%) risk factor in patients with mucosal candidiasis; patients with invasive candidiasis commonly had acute leukaemia/lymphoma (50%) or diabetes mellitus (31%). Most patients with mucosal candidiasis (91%) and invasive candidiasis (94%) were refractory to >/=1 antifungal agent(s). A favourable response was noted in 82% (14/17) with oesophageal candidiasis, 100% (4/4) with oropharyngeal candidiasis and 87% (13/15) with invasive candidiasis. Caspofungin was generally well tolerated; one serious drug-related adverse event was reported.

In this study, caspofungin was an effective alternative for patients with refractory candida infections.
