  • Publication number: 20210145740
    Abstract: Provided is a liposomal sustained-release composition for use in treatment of pulmonary disease. The liposomal sustained release composition comprises a liposome that includes a polyethylene glycol (PEG)-modified lipid and encapsulates a tyrosine kinase inhibitor. Tyrosine kinase inhibitor is stably entrapped in the liposome, and the resulting liposomal drug formulation can be aerosolized or nebulized for administration via inhalation. This aerosolized liposomal drug formulation yields consistent pharmacokinetic and pharmacodynamic profiles while achieving desired efficacy and safety.

  • Publication number: 20190160009
    Abstract: Provided is a method for preparing a liposomal composition. The method comprises the step of contacting a liposome solution with a mild acidic agent for a limited time. The liposome solution comprises a weak acid salt encapsulated within an aqueous interior space separated from the aqueous medium by a membrane comprised of a lipid mixture containing one or more lipids and a hydrophilic polymer conjugated lipid at a molar percentage of less than 3% based on the total amount of the lipid mixture. The time for encapsulating the agent to a desired amount at a predetermined ratio to lipids is dramatically reduced even under a condition without elevating the temperature to above ambient environment.
