Last Updated: 2019-10-16

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 24 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2011-09-30
• Study Completion Date: 2012-02-29

Brief Summary

The purpose of this study was to assess the bioavailability of total testosterone through pharmacokinetic profiles obtained following (a) single administration of three doses of TBS-2 b) multiple administration TBS-2.

In addition, assessing the bioavailability of free testosterone, dihydrotestosterone, SHBG and estradiol through pharmacokinetic profiles was also conducted.

Detailed Description

This is a 2 Period study that requires overnight stays in clinic. Blood samples are required at all visits including sampling at predefined time periods during the overnight stays.

Period I

Subjects were checked-in on Day 1 Period I to start their baseline testosterone measurement (dependant on menstrual cycle, preferably within 48hr of start of the menstrual cycle). They remained institutionalized until Day 4 morning, and were checked out after the 48 hour blood draw and study close-out for those that did not continue with Period II.

Period II (Multi-Dose)

At the end of Period 1, a total of 8 subjects sampled from these 3 cohorts, who were willing and able to continue with the multiple-dose portion of the study were selected to participate in Period 2. Subjects were institutionalized starting on Day 1 of Visit 3 until Day 5 morning of Visit 3, and were checked out after the 48 hour blood draw and study close-out.
