What participants receive

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

  • Comparator: low dose testosteroneDrug

    Subjects will receive two muscle biopsies, the first at baseline, and the second a week after a single intramuscular dose of 200 mg (0.8 mL) testosterone.

  • Comparator: high dose testosteroneDrug

    Subjects will receive two muscle biopsies, the first at baseline, and the second a week after a single intramuscular dose of 600 mg (2.4 mL) testosterone.

  • Comparator: placeboDrug

    Subjects will receive two muscle biopsies, the first at baseline, and the second a week after a single intramuscular dose of 0.8 mL placebo saline solution.

    Measured: 1 week

Secondary outcomes (1)
  1. mRNA or miRNA expression in the vastus lateralis or in peripheral blood

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Comparator: low dose testosterone and Comparator: high dose testosterone in people with Muscle Anabolism, run by Merck Sharp & Dohme LLC.

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 7 inclusion and 5 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 30 Jan 2015. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 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.

What does the primary outcome measure?

comparative proteomics on proteins present in the vastus lateralis or plasma (time frame: 1 week). 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 NCT00812396, 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 30 Jan 2015.
