Trial Outcomes & Findings for A Study of Effect of Deodorant and Axillary Hair on Testosterone Absorption in Healthy Participants (NCT NCT01725451)

NCT ID: NCT01725451

Last Updated: 2014-10-16

Results Overview

The AUC from time 0 to 72 hours \[AUC (0-72)\] postdose, based on baseline-corrected concentrations. Baseline-corrected AUC (0-72) was calculated using the measured concentrations of total testosterone minus mean baseline testosterone concentration. Baseline testosterone concentration was the arithmetic mean of 3 predose concentrations.

Measure
Testosterone 2% Solution
n=30 Participants
Participants randomized to 1 of 4 treatment sequences involving 6 treatments in each sequence. Each sequence involved 4 single-dose treatments of testosterone 2% solution to unshaved axillae with or without the use of deodorant or antiperspirant products followed by 2 single-dose treatments of testosterone 2% solution to shaved axillae with or without the use of deodorant or antiperspirant products. Each of the treatments was followed by 3 days of pharmacokinetic (PK) sampling and 1-day washout except that there was no washout after the last PK sample for the last treatment.

PRIMARY outcome

Timeframe: Pre-dose [60 to 45 minutes (min), 30 to 15 min, 5 minutes prior to each dose], 0.5, 1, 2, 4, 8, 12, 16, 24, 36, 48, and 72 hours after administration of study drug

Population: All randomized participants who received at least 1 dose of testosterone 2% solution and had evaluable 72-hour testosterone concentrations.

The AUC from time 0 to 72 hours \[AUC (0-72)\] postdose, based on baseline-corrected concentrations. Baseline-corrected AUC (0-72) was calculated using the measured concentrations of total testosterone minus mean baseline testosterone concentration. Baseline testosterone concentration was the arithmetic mean of 3 predose concentrations.
