  • Patent number: 11229602
    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.

  • Publication number: 20190343763
    Abstract: The invention relates to methods for locally delivering a chemotherapeutic agent to an upper tract urothelial carcinoma (UTUC). The methods involve placing a balloon catheter that has a working channel and a balloon into the ureter/renal pelvis via retrograde or antegrade ureteral access; inflating the catheter balloon to temporarily obstruct the ureter; infusing (instilling) a liposomal formulation that includes a chemotherapeutic agent into the working channel of the catheter; and allowing the infused liposomal formulation to dwell in the ureter and/or renal pelvis for a time sufficient to allow at least a portion of the liposomal formulation to adhere to the urothelial wall. In the methods of the invention, at least a portion of the infused chemotherapeutic-agent formulation adheres to the urothelial wall while it is instilled and dwells in the ureter and/or renal pelvis.

  • Publication number: 20190133946
    Abstract: This invention is directed to a novel method of treating an individual suffering from a bacterial infection, such as bacterial infections of various tissues or organs of an individual. In general, the method of treatment involves administering to an individual a pharmaceutical formulation that comprises a liposome-encapsulated antimicrobial agent, wherein polyethylene glycol (PEG) molecules are covalently attached to the surface of the liposomes.

  • Publication number: 20180311166
    Abstract: The invention relates to a novel free-flowing powder pharmaceutical formulation for the delivery of a poorly-water-soluble drug substance that increases the solubility and bioavailability of the poorly-water soluble drug substance, as well as to a method of making the free-flowing powder pharmaceutical formulation. The invention also relates to dispersed particles that disperse instantaneously from the free-flowing powder formulation when the formulation is added to water, aqueous solvent, or organic solvent, wherein the bulk distribution of the poorly-water soluble drug substance of the free-flowing powder formulation in the dispersed particles is uniform. Such dispersed particles increase the bioavailable surface area of the poorly water-soluble drug substance and facilitate the drug substance's dissolution.
