Brief summary

A One Year Clinical Trial Assessing the Usefulness and Safety of Inhaled Insulin in Diabetics with Chronic Obstructive Pulmonary Disease.

Detailed description

Pfizer announced in October 2007 that it would stop marketing Exubera. At that time recruitment for study A2171030 was placed on hold. Nektar, the company from which Pfizer licensed Exubera, announced on April 9, 2008 that it had stopped its search for a new marketing partner. Accordingly, there will be no commercial availability of Exubera. As a result, study A2171030 was terminated on June 17, 2008. Neither safety nor efficacy reasons were the cause of the study termination.

Interventions

Subcutaneous short-acting insulin with dose adjusted according to premeal blood glucose plus oral antidiabetic agent(s) and/or either once or twice daily doses of either Ultralente or neutral protamine hagedorn (NPH) insulin, or a single bedtime dose of insulin glargine.

Inhaled insulin with dose adjusted according to premeal blood glucose plus oral antidiabetic agent(s) and/or either once or twice daily doses of either Ultralente or NPH insulin, or a single bedtime dose of insulin glargine.

Change from baseline: mean of (value of observed FEV1 (L) at treatment duration minus baseline value).
Change From Baseline in Post-Bronchodilator Carbon Monoxide Diffusion Capacity (DLco)Baseline, Weeks 1, 2, 3, 4, 6, 12, 18, 26, 39, 52DLco measured in milliters/minutes/millimeters of mercury (mL/min/mmHg) 30 minutes following the administration of ipratropium.

Secondary

MeasureTime frameDescription
Other PFTs (Besides FEV1 and DLco)Duration of the studyOther PFTs (besides FEV1 and DLco) were measured 30 minutes following the administration of ipratropium. Other PFTs included forced vital capacity (FVC), peak expiratory flow rate (maximal forced expiratory flow) (PEFR\[FEFmax\]), and forced expiratory flow from 25% to 75% of vital capacity (FEF25%-75%). Other PFT data were collected, but not analyzed.
Bronchodilator Responsiveness as Determined by the Change in FEV1Weeks 1, 2, 3, 4, 6, 12, 18, 26, 39, 52Responsiveness was the percent change from the FEV1 value before bronchodilator use to the FEV1 value 30 minutes after bronchodilator use, operationally defined as \[(post-bronchodilator FEV1 minus pre-bronchodilator FEV1 divided by pre-bronchodilator FEV1\] multiplied by 100.
Insulin Dose Responsiveness for FEV1Baseline, Week 9, Week 51FEV1 dose responsiveness 10 and 60 minutes after insulin. FEV1 dose-responsiveness to insulin (defined as the difference between the FEV1 value following a dose of insulin and FEV1 value before a dose of insulin, operationally defined as the post-dose FEV1 value minus pre-dose FEV1 value).
Insulin Dose Responsiveness for DLcoBaseline, Week 9, Week 51DLco dose responsivness 10 and 60 minutes after insulin. DLco dose-responsiveness to insulin (defined as the difference between the DLco value following a dose of insulin and DLco value before a dose of insulin, operationally defined as the post-dose DLco value minus pre-dose DLco value).
Methacholine PC20Duration of the studyMethacholine challenge testing was conducted at selected sites at visits which did not occur at other sites (Weeks -2.9, -0.9, 11, 50 and 52+5). Methacholine challenge was not analyzed as there was only 1 test performed, which was a baseline test, and no methacholine tests performed in subjects using inhaled insulin.
Mean Weekly Number of Puffs of Short-Acting Bronchodilator UsedDuration of the studyAll subjects used diary cards to record their daily use of short-acting bronchodilators. Subjects recorded the sum of their short-acting bronchodilator use (puffs of albuterol plus ipratropium plus Combivent®, as applicable) daily, immediately upon arising, and again in the evening or before bed. Mean weekly number of puffs of short-acting bronchodilator used data were collected, but not analyzed.
Incidence of Non-Severe Chronic Obstructive Pulmonary Disease (COPD) Exacerbations0 to 1 week to > 9 monthsNon-severe COPD exacerbation = additional therapy (systemic corticosteroids, antibiotics, oxygen) needed for worsening respiratory symptoms and/or lung function, not needing hospitalization \> 24 hours. Crude event rate = total events divided by subject-months. Subject-months=elapsed number of months a subject was in the study in each time interval.
Incidence of Severe COPD Exacerbations0 to 1 week to > 9 monthsSevere COPD exacerbation = a COPD-related hospitalization \> 24 hours. Crude event rate = total events divided by subject-months. Subject-months=elapsed number of months a subject was in the study in each time interval.

Mean Weekly Number of Puffs of Short-Acting Bronchodilator Used

All subjects used diary cards to record their daily use of short-acting bronchodilators. Subjects recorded the sum of their short-acting bronchodilator use (puffs of albuterol plus ipratropium plus Combivent®, as applicable) daily, immediately upon arising, and again in the evening or before bed. Mean weekly number of puffs of short-acting bronchodilator used data were collected, but not analyzed.

Methacholine PC20

Methacholine challenge testing was conducted at selected sites at visits which did not occur at other sites (Weeks -2.9, -0.9, 11, 50 and 52+5). Methacholine challenge was not analyzed as there was only 1 test performed, which was a baseline test, and no methacholine tests performed in subjects using inhaled insulin.

Other PFTs (Besides FEV1 and DLco)

Other PFTs (besides FEV1 and DLco) were measured 30 minutes following the administration of ipratropium. Other PFTs included forced vital capacity (FVC), peak expiratory flow rate (maximal forced expiratory flow) (PEFR\[FEFmax\]), and forced expiratory flow from 25% to 75% of vital capacity (FEF25%-75%). Other PFT data were collected, but not analyzed.
