Detailed Description:
This Phase 1, single-dose trial is being conducted to determine if nephropathy affects the way the kidneys eliminate the byproducts of Technosphere® Inhalation Powder as compared to kidneys free of disease. This trial will test the safety, tolerability and pharmacokinetics of the study medication. The trial consists of a screening, dosing and a follow-up visit. Single dose administration of Technosphere® Inhalation Powder occurs at the dosing visit. (V2) with serum and urine PK testing .
