A Trial to Determine How Long Insulin and FDKP (the Molecule That Forms Technosphere Particles) Stays in the Lungs of Healthy Individuals After Inhalation of Technosphere® Insulin (TI) Powder Using Bronchoalveolar Lavage (BAL)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00757367

Mannkind Corporation

Brief Summary:
Lavage fluid (BAL) is inserted into a lung lobe using a flexible bronchoscope. The fluid is aspirated out to remove any remaining TI. It's performed twice at specific time points in 12 healthy volunteers. BAL fluid will be analyzed for insulin and FDKP.

Condition or disease Intervention/treatment Phase
Healthy Subjects Drug: TI Inhalation Powder Phase 1

Detailed Description:
Informed consent and eligibility occur at Screening. Dosing is at Visit 2. Blood glucose levels are monitored and adjusted using IV infusion of glucose. Bronchoalveolar lavage (BAL) is performed at 30 minutes and 6 hours for Cohort 1 and at 4 and 8 hours for Cohort 2, post TI dose. A series of blood samples are taken at specified timepoints. Cohort 3 will proceed with dosing if deemed necessary once analysis of BAL from Cohorts 1 & 2 is performed. Visit 3 is the follow-up safety visit.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 13 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1, Open-Label, Controlled Clinical Trial to Determine the Pulmonary Residence Time of Insulin and Fumaryl Diketopiperazine, Utilizing Bronchoalveolar Lavage, After Administration of Technosphere® Insulin Inhalation Powder in Healthy Subjects

Drug Information available for: Insulin

Arm Intervention/treatment
Experimental: TI Inhalation Powder
TI Inhalation Powder, single dose, 60 units
Drug: TI Inhalation Powder
1 60-U dose of TI Inhalation Powder before the bronchoscopy. Cohort 1 will undergo bronchoscopies at 30 minutes and again at 6 hours after the 60-U dose inhalation of TI Inhalation Powder. Cohort 2 bronchoscopies will occur at 4 hours and again at 8 hours after TI Inhalation Powder. The need to run and the timepoints for bronchoscopies for Cohort 3 will be determined based on the results from Cohort 1 and 2. All subjects will undergo 2 bronchoscopies at Visit 2.

Primary Outcome Measures :
  1. Estimation of the amount of insulin in the lungs and amount of FDKP by analyzing BAL fluid, obtained by a flexible fiber optic bronchoscope at various time points after admin of TI Inhalation Powder. [ Time Frame: 2 Months ]
