PURPOSE: Randomized phase II trial to study the effectiveness of oxandrolone in girls who have growth hormone-treated Turner's syndrome.

Read the detailed description

PROTOCOL OUTLINE: This is a randomized study. Patients are randomly assigned to recombinant human growth hormone (GH) and oxandrolone versus GH and placebo.

GH is administered by daily subcutaneous injection and oxandrolone is given every day by mouth. Treatment continues for 3 years; estrogen is offered after year 2.

A study duration of 8 years is anticipated.

Conditions: Turner's Syndrome
Being tested: growth hormone, oxandrolone

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing growth hormone and oxandrolone in people with Turner's Syndrome, run by National Institute of Neurological Disorders and Stroke (NINDS) at 1 site 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?

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 10 Sep 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00004275.

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 10 Sep 2008; AzTrials last refreshed its copy on 8 Nov 2026.
