研究概览
简要总结
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).
详细描述
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.
