Abstract
Compositions and methods for making and using proliposomal and liposomal formulations of chemotherapeutic agents are disclosed. The proliposomal and liposomal formulations of chemotherapeutics, as well as medicaments and dosage forms that include such formulations, can be used with treatment regimens for bladder cancer and urothelial cancer. Hence, the formulations, medicaments, and dosage forms of the invention are suitable to treat bladder cancers by intravesical administration and to treat urothelial cancers. The formulations according to the invention include (a) a taxane (e.g., paclitaxel, docetaxel) or cisplatin, (b) a first phospholipid, dipalmitoyl phosphatidylcholine (DMPC), and (c) a second phospholipid, dimyrsityl phosphatidyl glycerol sodium (DMPG). The proliposomal formulations form liposomes upon contact with an aqueous vehicle.
