NCT00747006
First received: September 3, 2008
Last updated: July 12, 2011
Last verified: July 2011
  Purpose

The purpose of this study is to determine if, once a favorable dose of TI Inhalation Powder is established for either a type 1 or 2 patient, based on a average diabetic meal, the patient's favorable dose can be used safely, regardless of change in meal carbohydrate content.

Primary Outcome Measures:
  • PPG excursions following the ingestion of lunch or breakfast meals with varying carbohydrate contents at 30, 60, 90, 105, 120, 180 and 240 minutes post dose. [ Time Frame: 15 Weeks ] [ Designated as safety issue: No ]

Enrollment: 18
Study Start Date: September 2008
Study Completion Date: May 2011
Primary Completion Date: February 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TI Inhalation Powder (original protocol)
Under the original protocol, subjects with Type 1 and Type 2 diabetes will have TI Inhalation Powder administered prandially during dose optimization visits and meal challenge visits (with meals of varying carbohydrate contents). Subjects with Type 2 diabetes will also use TI Inhalation Powder daily at each meal between visits.
Drug: TI Inhalation Powder (original protocol)
Inhaled insulin technology to be administered immediately before a meal (prandially) for glucose control in Type 1 or Type 2 diabetics
TI Inhalation Powder and Humalog (Amendment 1)
Under Amendment 1, TI Inhalation Powder will be administered prandially to a new subset of subjects with Type 2 diabetes during TI dose optimization visits and TI meal challenge visits (with meals of varying carbohydrate contents). Subjects will be crossed over to administration of Humalog 15 minutes before meals during Humalog dose optimization visits and Humalog meal challenge visits (with meals of varying carbohydrate contents). Subjects will also use TI Inhalation Powder daily at each meal between visits.
Drug: TI Inhalation Powder and Humalog (Amendment 1)
Subcutaneous (sc) rapid acting analog to be administered at one half of the meal challenge visits 15 minutes before a meal. Only the last 5 - 10 patients (Type 2) will be undergoing this amendment to the protocol.
