Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We propose oral dosing of gastrointestinal permeation enhancement technology \[GIPET\] enhanced oral acyline at 20 mg everyday for one week to determine the steady-state (multiple-dose) pharmacokinetics of oral acyline in four normal, healthy young men.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to test how the body responds to a new oral form of acyline given for seven days and to also look at the safety of oral acyline.

Acyline temporarily blocks the production of the hormone testosterone in healthy men. It has been tested in over 100 men in an injection form. This study will be testing acyline in a pill form for seven days.

This study may help develop an oral form of testosterone-blocker which may be useful in the treatment of diseases such as prostate cancer, premature puberty and possibly in a male contraceptive.

This study will evaluate a single dose of oral acyline given once a day for seven days and subsequent effects on Testosterone, FSH and LH blood serum concentrations.
