A Study Designed to Compare 2 Dose Strengths of TI Inhalation Powder in Adults With Type 1 Diabetes Mellitus and to Compare One of Those Formulations (30Units) With an Injection of Insulin Lispro
A Phase 2, Open-Label, Randomized, 2-Way Crossover, Clinical Trial to Compare the Pharmacokinetics of 2 Formulations of "Intended Commercial Product" Technosphere® Insulin Inhalation Powder and to Determine the Bioavailability of a 30 Unit Cartridge of "Intended Commercial Product" Technosphere® Insulin Inhalation Powder Versus a 10 Unit Subcutaneous Injection of Insulin Lispro in Subjects With Type 1 Diabetes Mellitus
