About this study
Official title: Pharmacokinetics of Modified Slow-Release Oral Testosterone Over 10 Days in Normal Men With Experimental Hypogonadism
The purpose of this study is to test how the body absorbs a new form of oral testosterone (T). On Day 1 and Day 9 there are overnight stays in the General Clinical Research Center at the University of Washington to monitor blood testosterone levels over a 24-hour period.
Read the detailed description
We will administer two experimental drugs, acyline and oral testosterone. Acyline shots will be given on Day 0 to turn off the body's testosterone production for about 10-14 days.
The next day, Day 1, subjects begin taking 300 mg modified slow-release testosterone pill by mouth, three times a day, around 9 AM, 1 PM, and 7 PM for a total of 27 pills.
There are overnight stays on Day 1 and Day 9 to allow monitoring of blood testosterone levels over a 24 hour period, from @9 AM to 9 AM the next morning. At those visits, blood is drawn at baseline (before taking the pill) and at 1, 2, 4, 5, 6, 8, 10, 11, 12, 14, 16, and 24 hours after the morning dose.
Acyline is an experimental drug. The FDA allows its use only in research with a small number of volunteers. We have used acyline in over 125 men without serious side effects. The use of testosterone in this study is experimental and there may be unknown or unanticipated risks.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to test how the body absorbs a new form of oral testosterone (T). On Day 1 and Day 9 there are overnight stays in the General Clinical Research Center at the University of Washington to monitor blood testosterone levels over a 24-hour period.
Detailed description
We will administer two experimental drugs, acyline and oral testosterone. Acyline shots will be given on Day 0 to turn off the body's testosterone production for about 10-14 days.
The next day, Day 1, subjects begin taking 300 mg modified slow-release testosterone pill by mouth, three times a day, around 9 AM, 1 PM, and 7 PM for a total of 27 pills.
There are overnight stays on Day 1 and Day 9 to allow monitoring of blood testosterone levels over a 24 hour period, from @9 AM to 9 AM the next morning. At those visits, blood is drawn at baseline (before taking the pill) and at 1, 2, 4, 5, 6, 8, 10, 11, 12, 14, 16, and 24 hours after the morning dose.
Acyline is an experimental drug. The FDA allows its use only in research with a small number of volunteers. We have used acyline in over 125 men without serious side effects. The use of testosterone in this study is experimental and there may be unknown or unanticipated risks.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Oral Testosterone and Acyline in people with Healthy, run by University of Washington 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 3 inclusion and 4 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 6 Sep 2013. 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?
Yes. Results are posted in the registry (first posted 23 Aug 2013). 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?
Maximum Testosterone Concentration (time frame: baseline & day 9). 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?
On the ClinicalTrials.gov record for NCT01167829, which also lists 17 linked publications.
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 6 Sep 2013.
