Safety and Efficacy of Technosphere® Insulin Inhalation Powder (TI Inhalation Powder)When an Optimal Dose is Taken With Varied Carbohydrate Intake
2014년 10월 21일 업데이트: Mannkind Corporation
A Phase 2, Single-Center, Open-Label, Pharmacodynamic Clinical Trial to Evaluate the Effect of Technosphere® Insulin Inhalation Powder Safety and Efficacy of Technosphere® Insulin Inhalation Powder (TI Inhalation Powder) Safety and Efficacy of Technosphere® Insulin Inhalation Powder (TI Inhalation Powder) on Postprandial Glucose Levels in Subjects With Type 1 and Type 2 Diabetes Mellitus Ingesting Meals With Varied Carbohydrate Content
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.
Patients were randomly assigned to various carbohydrate loads (0%, 50%, 100%, 150% or 200%).
The 100% carbohydrate load was determined based upon their standard insulin dose for their normal meal.

실험적: 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.
|
Inhaled insulin technology to be administered immediately before a meal (prandially) for glucose control in Type 1 or Type 2 diabetics
|
|
다른: 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.
|
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.
