About this study

Official title: An Open-Label, Uncontrolled Long-Term Safety Study Of CP-464,005 (Inhaled Insulin) In Japanese Patients With Type 1 Or Type 2 Diabetes

Assess the safety and toleration of CP-464,005 and Inhaler following 1-year (52 week) administration to Type 1 and Type 2 diabetes patients (non-smokers)

Read the detailed description

Pfizer announced in October 2007 that it would stop marketing CP-464,005. At that time recruitment for study, A2171105 was placed on hold. Nektar, the company from which Pfizer licensed CP-464,005, announced on April 9, 2008 that it had stopped its search for a new marketing partner. As a result, study A2171105 was terminated on April 10, 2008. Neither safety nor efficacy reasons were the cause of the study termination.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CP-464,005Drug

    Also called Exubera

    Taken for 1 year (52 weeks) immediately before each meal (breakfast, lunch, and supper). Dose: adjusted based on the results of self-monitoring of blood glucose before each meal.

  • CP-464,005Drug

    Also called Exubera

    Taken for 1 year (52 weeks) immediately before each meal (breakfast, lunch, and supper). Dose: adjusted based on the results of self-monitoring of blood glucose before each meal.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Self-Monitoring Blood Glucose Levels: Change From Baseline

    Self-monitoring blood glucose levels obtained at each observation point minus that at baseline.

    Measured: One year

Secondary outcomes (8)
  1. Daily Inhaled Insulin Dose

    The mean of daily inhaled insulin dose. The dose of inhaled insulin was adjusted based on the results of self-monitoring of blood glucose before each meal.The end of treatment values were calculated each subject's last observed value up to 26 weeks.

    Measured: Up to 26 weeks

  2. The Values of Hemoglobin A1c:Change From Baseline

    Hemoglobin A1c levels obtained each observation point minus that at baseline. The end of treatment values were calculated each subject's last observed value up to 26 weeks.

    Measured: Baseline, Week 6, Week 12, Week 26, End of treatment

  3. The Value of Fasting Plasma Glucose:Change From Baseline

    Fasting plasma glucose levels obtained at each observation point minus that at baseline. The end of treatment values were calculated each subject's last observed value up to 26 weeks.

    Measured: Baseline, Week 6, Week 12, Week 26

  4. The Incidence of Hypoglycaemia at the Cumulative Doses of Inhaled Insulin

    Number of hypoglycemic events per subject-month. Subject-month=(number of days from the first day of study treatment to the last day of active treatment + 1 day lag)/30.44

    Measured: 0 month to 12 months

  5. The Values of Forced Expiratory Volume at 1 Second:Change From Baseline

    Pulmonary function test(forced expiratory volume at 1 second) obtained at each observation point minus that at baseline. The end of treatment values were calculated each subject's last observed value up to 26 weeks.

    Measured: Beseline, Week 1, Week 2, Week 6, Week 12, Week 26

  6. The Values of Forced Vital Capacity:Change From Baseline

    pulmonary function test(forced vital capacity) obtained at each observation point minus that at baseline. The end of treatment values were calculated each subject's last observed value up to 26 weeks.

    Measured: Baseline, Week 1, Week 2, Week 6, Week 12, Week 26, End of treatment

  7. The Values of Forced Expiratory Volume at 1 Second/Forced Vital Capacity:Change From Baseline

    Pulmonary function test(forced expiratory volume at 1 second/forced vital capacity) obtained at each observation point minus that at baseline. The end of treatment values were calculated each subject's last observed value up to 26 weeks.

    Measured: Baseline, Week 1, Week 2, Week 6, Week 12, Week26, End of treatment

  8. Insulin Antibody Levels : Change From Baseline

    Insulin antibody levels obtained at each observation point minus that at baseline. The end of treatment values were calculated each subject's last observed value up to 26 weeks.

    Measured: Baseline, Week 6, Week 12, End of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing CP-464,005 in people with Diabetes Mellitus, Type 2 and Diabetes Mellitus, Type 1, run by Pfizer at 10 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 15 Oct 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Oct 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Self-Monitoring Blood Glucose Levels: Change From Baseline (time frame: One year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Oct 2009.
