About this study

Official title: Effect of Varying Testosterone Levels on Insulin Sensitivity in Men With Idiopathic Hypogonadotropic Hypogonadism

The investigators are doing this research study to look at the relationship between testosterone (the main sex hormone in men) and insulin (the hormone that controls blood sugar levels) in men with Idiopathic Hypogonadotropic Hypogonadism (IHH).

The investigators hypothesize that normalizing testosterone levels in men with IHH enhances insulin sensitivity, reduces visceral fat, increases lean body mass, and improves the lipid profile.

Being tested
Anastrozole Pill, Testosterone, Placebo Oral Tablet
Keywords

What is being measured

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

  1. Change in glucose tolerance

    Response to 75 g glucose load

    Measured: Change between baseline and 3 months

  2. Change in insulin sensitivity

    IV glucose tolerance test

    Measured: Change between baseline and 3 months

Secondary outcomes (2)
  1. Change in visceral fat

    Assessed by CT of abdomen

    Measured: Change between baseline and 3 months

  2. Change in resting energy expenditure

    Assessed by metabolic monitor

    Measured: Change between baseline and 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Anastrozole Pill and Testosterone in people with Hypogonadotropic Hypogonadism and Kallmann Syndrome, run by Massachusetts General Hospital 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?

The sponsor lists 5 inclusion and 8 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 18 Apr 2017. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 was stopped early (reason given: Because the PI left the institution.). Results are not available in the source record.

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?

Change in glucose tolerance (time frame: Change between baseline and 3 months). The study lists 2 primary outcomes in all. 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 18 Apr 2017.
