Abstract: Methods are provided for extracting one or more neutrophil serine proteases (NSPs), e.g., neutrophil elastase (NE), proteinase 3 (PR3), cathepsin G (CatG), neutrophil serine protease 4 (NSP4), or a combination thereof, from a sample comprising white blood cells (WBCs) obtained from a subject. The extraction methods feature the use of nonionic surfactants and two or more cycles of repeated lysis of WBCs and their residuals. Also provided are methods for treating dipeptidyl peptidase 1 (DPP1)-mediated conditions in a patient with compositions comprising certain N-(1-cyano-2-phenylethyl)-1,4-oxazepane-2-carboxamide compounds of formula (I), including pharmaceutically acceptable salts thereof, that reversibly inhibit (DPP1) activity. The treatment methods provided herein use the concentration of active NSPs extracted from a patient's WBC sample as a biomarker to guide the selection of, or adjustment to, an effective dosage of the compounds of formula (I).

Abstract: Methods of treatment of NTM lung infections using formulations of liposomal ciprofloxacin. Specific liposome formulations and delivery of such for treatment of respiratory tract infections and other medical conditions, and devices and formulations used in connection with such are described.

Abstract: A concentrated inhalable formulation of an antibiotic drug such as ciprofloxacin is disclosed. The antibiotic is formulated with sodium acetate and liposome which incorporate antibiotic. The formulation is aerosolized and inhaled for treatment of respiratory tract infections and other medical conditions.

Abstract: Methods of treatment of NTM lung infections using formulations of liposoma ciprofloxacin. Specific liposome formulations and delivery of such for treatment of respiratory tract infections and other medical conditions, and devices and formulations used in connection with such are described.

Abstract: An aerosolizable formulation comprised of a drug, a carrier and pH affecting component is disclosed. The Drug is dissolved in the formulation at a concentration above which it remains in solution at neutral pH. This increases the concentration of the drug in solution making it possible to administer larger amounts of drug with the same or a smaller volume of formulation. When the formulation is aerosolized to small particles and inhaled into human lungs in small volumes (e.g. 0.05 to 0.5 mL) the fluids in the lungs neutralize the formulation causing the drug to participate out of solution. This results in the drug being delivered at a controlled rate below the rate at which drug is administered from a formulation initially at a neutral pH.
