Pfizer
  Purpose
In studies of Exubera in persons with diabetes, lung cancer occurred in a few more people who were taking Exubera than in people who were taking other diabetes medicines. All subjects diagnosed with lung cancer had a history of smoking and the number of lung cancer cases observed fell within the expected range based on population-based data. There is currently not enough information to determine if any of the observed lung cancer cases were related to Exubera use, therefore, the study is being conducted to further investigate whether Exubera use makes the appearance of lung cancer more likely.

Condition Intervention
Diabetes Mellitus Drug: Exubera Other: Randomized diabetes therapy

Study Type: Observational
Study Design: Observational Model: Cohort
Official Title: An Observational Follow-Up Study Of Patients Previously Enrolled In Exubera Controlled Clinical Trials

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Rate of Primary Lung Cancer Mortality [ Time Frame: Baseline from original trial up to Year 2 of this study ]
    Reported deaths from primary lung cancer were adjudicated and classified into 4 categories: highly likely (clinical, radiographic, and/or histological data consistent with primary lung cancer); likely (some information may have been missing for definite diagnosis); unlikely; insufficient information. Highly likely and likely cases used to report rate and rate ratio of primary lung cancer mortality. Includes events from the start of the original trial to the end of FUSE.


Secondary Outcome Measures:
  • Rate of Primary Lung Cancer Mortality Among Former Smokers [ Time Frame: Baseline from original trial up to Year 2 of this study ]
    Reported deaths from primary lung cancer were adjudicated and classified into 4 categories: highly likely (clinical, radiographic, and/or histological data consistent with primary lung cancer); likely (some information may have been missing for definite diagnosis); unlikely; insufficient information. Highly likely and likely cases used to report rate and rate ratio of primary lung cancer mortality. Includes events from the start of the original trial to the end of FUSE.

  • Rate of All-cause Mortality [ Time Frame: Baseline from original trial up to Year 2 of this study ]
    The rate and rate ratio of all-cause mortality that occurred anytime from the start of the original trial to the end of FUSE.

  • Rate of Primary Lung Cancer Diagnosis [ Time Frame: Baseline from original trial up to Year 2 of this study ]
    The rate and rate ratio of lung cancer adjudicated as highly likely (clinical, radiographic, and/or histological data consistent with primary lung cancer) or likely (some information may have been missing for definite diagnosis) to be newly diagnosed primary lung cancer that occurred anytime from the start of the original trial to the end of FUSE.


Enrollment: 7439
Study Start Date: August 2008
Study Completion Date: January 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Previously treated with Exubera Drug: Exubera
Subjects who had been treated with Exubera in a prior Exubera controlled trial. Following initial use of randomized treatment, physicians and subjects were free to change regimens and dosing based on subject response to assigned treatment (as consistent with routine practice).
Previously treated with comparator
Subjects who had been treated with a comparator (other diabetes treatment such as injected insulin) in a prior Exubera controlled trial.
Other: Randomized diabetes therapy

Subjects who had been treated with a comparator (other diabetes treatment including one or more of: subcutaneous insulin, sulfonylureas, biguanides, or thiazolinediones) in a prior Exubera controlled trial.

Following initial use of randomized treatment, physicians and subjects were free to change regimens and dosing based on subject response to assigned treatment (as consistent with routine practice).


Detailed Description:
Both retrospective and prospective components All subjects who participated in one of the 17 included Exubera clinical trials will be invited to participate in the current study.
