研究概览
简要总结
This study will evaluate the effect of deodorant and antiperspirant use and the presence of underarm hair on the absorption of testosterone. Each participant in this study will receive 6 single doses of 30 milligrams (mg) testosterone applied as a solution to each underarm. There is a minimum one day washout period between each dose. This study will last approximately 24 days not including screening. Screening is required within 30 days prior to the start of the study.

入选标准
- •Are overtly healthy males, as determined by medical history and physical examination
- •Agree to use a reliable method of birth control (for example, condom or vasectomy) during the study and for 1 month following the last dose of testosterone
- •Have a total testosterone level <400 nanograms per deciliter (ng/dL) based on local laboratory result

- •Have an abnormal prostate-specific antigen (PSA) test result
- •Have known allergies to testosterone solution, related compounds or any components of the formulation, or history of significant atopy
- •Have an abnormality in the 12-lead electrocardiogram (ECG) that, in the opinion of the investigator, increases the risks associated with participating in the study
- •Have an abnormal blood pressure as determined by the investigator
- •Regularly use known drugs of abuse and/or show positive findings on urinary drug screening
- •Show evidence of hepatitis B and/or positive hepatitis B surface antigen
- •Show evidence of hepatitis C and/or positive hepatitis C antibody
- •Show evidence of human immunodeficiency (HIV) infection and/or positive human HIV antibodies
- •Are participants who have previously completed or withdrawn from this study or any other study investigating testosterone
- •Are currently enrolled in, or discontinued within the last 30 days from, a clinical trial involving an investigational product or nonapproved use of a drug or device (other than the investigational product used in this study), or are concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study
- •In the opinion of the investigator or sponsor, are unsuitable for inclusion in the study
- •Have shaved the axillae within 3 months of screening

结局指标
主要结局
Pharmacokinetics: Maximum Drug Concentration (Cmax) of Testosterone
时间窗: 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
The Cmax from time 0 to 72 hours postdose, based on baseline-corrected concentrations. Baseline-corrected Cmax 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.
Pharmacokinetics: Area Under the Concentration Curve (AUC) of Testosterone
时间窗: 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
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.
