Clinical Trial Evaluating the Efficacy and Safety of Technosphere® Inhalation Insulin (TI) Inhalation Powder Using the Gen2 Inhaler

Phase 3
Terminated
Conditions
Type 2 Diabetes
Interventions
Drug: Technosphere® Insulin Inhalation Powder
Registration Number
NCT01196104
Lead Sponsor
Mannkind Corporation
Brief Summary

This is an open-label, randomized, forced-titration clinical trial evaluating the efficacy and safety of Technosphere Insulin (TI) Inhalation Powder in combination with insulin glargine versus insulin aspart in combination with insulin glargine in subjects with type 2 diabetes.

Detailed Description

Phase 3 clinical trial is designed to examine the efficacy and safety of inhaled prandial TI Inhalation Powder in combination with basal insulin verses insulin aspart in combination with basal insulin in subjects with type 2 diabetes who are suboptimally controlled with their current insulin regimens.This trial will employ a variety of methods to intensively manage these subjects.

Exclusion criteria:

  • Current or prior treatment with prandial or PreMix (70/30) insulin
  • History of insulin pump use within 6 weeks of Visit 1
  • Treatment with Glucagon-like Peptide (GLP-1) analog drugs within the preceding 12 weeks of Visit 1
  • History of chronic obstructive pulmonary disease (COPD), asthma, or any other clinically important pulmonary disease (eg, pulmonary fibrosis)
  • Any clinically significant radiological findings on screening chest x-ray
  • Use of medications for asthma, COPD, or any other chronic respiratory conditions
  • Evidence of serious complications of diabetes (eg, symptomatic autonomic neuropathy)
  • Significant cardiovascular dysfunction or history within 3 months of Visit 1 (eg, congestive heart failure [New York Heart Association {NYHA} Class III or IV])
  • Serious arrhythmia, myocardial infarction, cardiac surgery, recurrent syncope, transient ischemic attacks, or any cerebrovascular accident
  • History of pulmonary embolism or deep venous thrombosis in the 12 months before Screening (Visit 1)

Severe hypoglycemia is defined as a subject who requires the assistance of another individual (not merely requested) and either:

* SMBG levels ≤ 36 mg/dL OR

* There is a prompt response to the administration of carbohydrate, glucagon, or other resuscitative measures
