About

This is an Open-label, randomized study in Type 1 diabetics looking at exposure and response (PK/PD) of TI using GEN2C Inhaler versus rapid acting analog.

Full description

Subjects with Type 1 diabetes will be randomized to either one dose of TI inhaled using the Gen2C device, or one dose of subcutaneously injected Rapid Acting Analog (RAA) and crossed over.

Crossover Sequences:

Sequence #1: Period 1 - one 20 U cartridge of TI; Period 2 - 8 U of RAA

Sequence #2: Period 1 - 8 U RAA; Period 2 - one 20 U cartridge of TI

An euglycemic clamp procedure will be performed at each dosing visit. The purpose of this study is to characterize the pharmacokinetics (PK) of the one dose of TI Inhalation Powder using the Gen2C inhaler as compared to one dose of subcutaneous RAA.

Current treatment with pramlintide acetate or exenatide
Unstable diabetes control and evidence of severe complications of diabetes (ie, autonomic neuropathy)
History of chronic obstructive pulmonary disease (COPD) or asthma, or any other clinically important pulmonary disease confirmed by pulmonary function testing or radiologic findings
Upper respiratory tract infection within 8 weeks before screening

Postmenopausal for the purposes of this clinical study includes experiencing amenorrhea for 2 or more years or being surgically sterile
Inability, in the opinion of the PI or a designee, to adequately inhale TI Inhalation Powder
Any subject who, in the opinion of the PI or a designee, appears to not be qualified for this study
