Brief Summary:
The purpose of this study is to evaluate the long-term pulmonary and cardiovascular safety of Exubera in routine clinical practice.

Condition or disease Intervention/treatment Phase
Diabetes Mellitus Drug: Randomization to Exubera (insulin human [rDNA origin] inhalation powder) or Usual Diabetes Care Phase 4

Detailed Description:
Pfizer announced in October 2007 that it would stop marketing Exubera. At that time, Pfizer committed to continued marketing until it returned the licensing rights for the technology to Nektar. Following the announcement, enrollment was halted. Subjects already enrolled and receiving treatment at the time of the halt in enrollment could continue in the study in accordance with the protocol. 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, an amendment was filed on April 16, 2008 specifying that all subjects randomized to Exubera had to be transitioned to usual diabetes care, and all study subjects followed for serious adverse events for 6 months. In accordance with this amendment, study A2171069 was terminated on April 29, 2009. Neither safety nor efficacy reasons were the cause of the study termination.

Arm Intervention/treatment
Experimental: Exubera Drug: Randomization to Exubera (insulin human [rDNA origin] inhalation powder) or Usual Diabetes Care
Subjects are randomized to use Exubera. Following initial use of randomized treatment, physicians and subjects are free to change regimens and dosing based on subject response to assigned treatment (as consistent with routine practice). Enrolling physicians are provided with the approved local label for Exubera to guide prescribing and treatment decisions.

Active Comparator: Usual Diabetes Care Drug: Randomization to Exubera (insulin human [rDNA origin] inhalation powder) or Usual Diabetes Care
Subjects are randomized to use usual diabetes care. Following initial use of randomized treatment, physicians and subjects are free to change regimens and dosing based on subject response to assigned treatment (as consistent with routine practice).
Other Name: Non-Exubera




Primary Outcome Measures :
  1. Number of Subjects With Decline in Forced Expiratory Volume (FEV1) Exceeding 20% From Baseline [ Time Frame: Baseline, Month 6, Year 1, Year 2, Index Visit ]
    Persistent decline in FEV1 exceeding 20% from baseline: observed decline in FEV1 exceeding 20% from baseline, 3 months after a confirmed decline (2 consecutive declines within 1 month) in FEV1 exceeding 20% from baseline. Second pulmonary function test (PFT) that confirmed decline was to occur within 14-42 days of the decline. Persistence: PFT that established persistence was to occur within 60-120 days of the confirming (2nd) decline. Index Visit: date subject had final Scheduled spirometry; was to occur within 2 months of Institutional Review Board/Ethics approval of April 2008 amendment.

  2. Supplemental Definition of Decline in Forced Expiratory Volume in One Second (FEV1): Number of Subjects [ Time Frame: Baseline, Month 6, Year 1, Year 2, Index Visit ]
    Confirmed FEV1 decline: any two consecutive declines that are >= 14 days apart. The pulmonary function test that established persistence occured >= 60 days after the initial decline. A confirmed decline: any two consecutive declines ≥ 14 days apart. The third PFT that established persistence was to occur ≥ 60 days after the initial decline. Index Visit: date the subject had his/her final scheduled spirometry was to occur within 2 months of Institutional Review Board/Ethics approval of April 2008 amendment.

  3. Time to Persistent Decline in FEV1 Exceeding 20% From Baseline [ Time Frame: Baseline to 5 years ]
    Elapsed time, in days, from the start of subject's participation in the study to the first reading of FEV1 that is: 20% or more below the subject's latest pre-study measurement, subsequently confirmed as a >20% decline [(baseline observed value minus visit observed value)/by baseline observed value *100], and assessed as persistent as defined by protocol process. Censoring time: elapsed time, in days, from the start of a subject's participation in the study to latest valid FEV1 measurement for the particular analysis set of interest. Cox proportional hazards model to estimate treatment effect.


Secondary Outcome Measures :
  1. Change From Baseline in Forced Expiratory Volume in One Second (FEV1) [ Time Frame: Baseline, Week 26, Week 52, Week 104, Index Visit ]
    Change from Baseline: mean of value of observed forced expiratory volume in the first second of forced exhalation [FEV1] in liters [L] at observation minus Baseline value. Index Visit: date subject had final scheduled spirometry; was to occur within 2 months of Institutional Review Board/Ethics approval of April 2008 amendment.

  2. Pulmonary Serious Adverse Event (SAE) Composite: SAEs of Asthma, Chronic Obstructive Pulmonary Disease (COPD), Pneumonia, or Acute Bronchitis [ Time Frame: Baseline through End of Study ]
    Endpoint committee adjudicated the endpoint based on review of medical and hospital records, and results were classified using standard criteria. Definite: definite pneumonia, definite COPD, or definite asthma; possible: possible pneumonia, possible COPD, possible asthma, probable obstructive lung disease not otherwise specified or probable acute bronchitis; definite or possible: either definite or possible; insufficient: insufficient data.

  3. Time to Event for Pulmonary Serious Adverse Event (SAE) Composite: SAEs of Asthma, Chronic Obstructive Pulmonary Disease (COPD), Pneumonia, or Acute Bronchitis [ Time Frame: Baseline to 5 years ]

Censoring time: elapsed time, in days, from the start of a subject's participation in the study to the latest contact with the subject for the particular analysis set of interest. Cox proportional hazards model to estimate treatment effect.

  4. All-cause Mortality: Number of Deaths [ Time Frame: Baseline through End of Study ]
    Endpoint committee adjudicated the endpoint based on review of medical and hospital records, and results were classified using standard criteria (confirmation of deaths by blinded adjudicator(s) through medical records or death certificates). Patients meeting the endpoint All Cause Mortality after adjudication by the endpoint committee.

  5. Time to Event: All-cause Mortality [ Time Frame: Baseline to 5 years ]
