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

October 9, 2014 updated by: Mannkind Corporation

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

28 subjects to be enrolled for a screening period, 3 dosing visits & a follow-up visit. Visits 2 and 3 dosing of TI Inhalation Powder, cross over between two 15 U cartridges and one 30 U cartridge. Visit 4 dosing will be a sc injection of 10 IU of RAA (rapid-acting insulin analogue).

Study Overview

Detailed Description

28 eligible subjects were planned to be enrolled to determine bioequivalence and safety parameters of two 15 U TI Inhalation Powder cartridges versus one 30 U TI Inhalation Powder cartridge, according to a randomized, 2-way crossover design. Additionally, bioavailability of one 30 U TI Inhalation Powder cartridge to a single subcutaneous injection of 10 IU of RAA will be compared.
