CANCIDAS is a sterile, lyophilized product for intravenous infusion that contains a semi-synthetic lipopeptide (echinocandin) compound synthesized from a fermentation product of Glarea lozoyensis. CANCIDAS is the first of a new class of antifungal drugs (echinocandins) that inhibit the synthesis of β (1,3)-D-glucan, an integral component of the fungal cell wall.
