  • Insulin Dose Responsiveness for DLco [ Time Frame: Baseline, Week 9, Week 51 ] [ Designated as safety issue: Yes ]
  • Methacholine PC20 [ Time Frame: Duration of the study ] [ Designated as safety issue: No ]
  • Mean Weekly Number of Puffs of Short-Acting Bronchodilator Used [ Time Frame: Duration of the study ] [ Designated as safety issue: No ]
  • Incidence of Non-Severe Chronic Obstructive Pulmonary Disease (COPD) Exacerbations [ Time Frame: 0 to 1 week to > 9 months ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Active Comparator: Subcutaneous Insulin Drug: Subcutaneous Insulin
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.
Experimental: Inhaled Insulin Drug: Inhaled Insulin
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.

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.
