What is being measured

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

  1. Percentage of Dyads (Participant and Caregiver or Parent) Reporting no Difference or Easier to Use for New Genotropin Mark VII Injection Pen Compared to Pre-study Experience With the Genotropin Pen®

    Ease of use measured using the Injection Pen Assessment Questionnaire (IPAQ) patient-reported outcome (PRO) tool (based on 13 unique characteristics of injection pens). Section I measures ease of use of Genotropin® (very easy, somewhat easy, neither easy nor difficult, somewhat difficult, or very difficult). Section II measures ease of use of new Genotropin Mark VII Pen in comparison to pre-study experience with Genotropin® Pen (Genotropin® pen easier to use, new injection pen easier to use, or no difference) and preference (prefer Genotropin® Pen, prefer new injection pen, or no preference).

    Measured: 2 months

Secondary outcomes (3)
  1. Percentage of Dyads Reporting no Preference or Preference for New Genotropin Mark VII Injection Pen Compared to Pre-study Experience With the Genotropin Pen®

    Preference for use measured using IPAQ PRO tool (ease of use and preference based on 13 unique characteristics of injection pens). Section I measures ease of use of Genotropin® (very easy, somewhat easy, neither easy nor difficult, somewhat difficult, or very difficult). Section II measures ease of use of new Genotropin Mark VII Pen in comparison to pre-study experience with Genotropin® Pen (Genotropin® Pen easier to use, new injection pen easier to use, or no difference) and preference (prefer Genotropin® Pen, prefer new injection pen, or no preference).

    Measured: 2 months

  2. Percentage of Dyads Reporting New Genotropin Mark VII Injection Pen Easier to Use Compared to Pre-study Experience With the Genotropin Pen®

    Ease of use measured using the IPAQ PRO tool (ease of use and preference based on 13 unique characteristics of injection pens). Section I measures ease of use of Genotropin® Pen (very easy, somewhat easy, neither easy nor difficult, somewhat difficult, or very difficult). Section II measures ease of use of new Genotropin Mark VII Pen in comparison to pre-study experience with Genotropin® Pen (Genotropin® Pen easier to use, new injection pen easier to use, or no difference) and preference (prefer Genotropin® Pen, prefer new injection pen, or no preference).

    Measured: 2 months

  3. Percentage of Dyads Reporting New Genotropin Mark VII Injection Pen Preferable Compared to Pre-study Experience With the Genotropin Pen®

    Preference for use measured using IPAQ PRO tool (ease of use and preference based on 13 unique characteristics of injection pens). Section I measures ease of use of Genotropin® (very easy, somewhat easy, neither easy nor difficult, somewhat difficult, or very difficult). Section II measures ease of use of new Genotropin Mark VII Pen in comparison to pre-study experience with Genotropin® Pen (Genotropin® Pen easier to use, new injection pen easier to use, or no difference) and preference (prefer Genotropin® Pen, prefer new injection pen, or no preference).

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing New Genotropin Pen in people with Growth Hormone Deficiency and Idiopathic Short Stature, run by Pfizer at 25 sites in United States.

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 3 inclusion and 3 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: finished, as of the sponsor's last update on 28 Jan 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 25 sites in United States. 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 23 Dec 2010). 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?

Percentage of Dyads (Participant and Caregiver or Parent) Reporting no Difference or Easier to Use for New Genotropin Mark VII Injection Pen Compared to Pre-study Experience With the Genotropin Pen® (time frame: 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00965484, which also lists 1 linked publication.

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 28 Jan 2011.
