Oxandrolone in Healthy Adults: A Relative Bioavailability Study

Phase 1
Completed
Conditions
Bioavailability
Interventions
Registration Number
NCT03218631
Lead Sponsor
University of Utah
Brief Summary

To assess the pharmacokinetics and relative bioavailability of a single dose of approximately 0.1 mg/kg of a medium chain triglyceride (MCT) oil oxandrolone solution vs. tablets in a small cohort of healthy adults.

Detailed Description

The results of this study will provide data regarding the relative bioavailability of a novel preparation of oxandrolone in MCT oil, which will allow dosing in neonates and small infants. This pilot study will provide information to design a larger multicenter study of neonates undergoing surgery for complex congenital heart disease.

GroupInterventionDescription
OxandrinOxandrinAdministration of a single dose of approximately 0.1 mg/kg of a medium chain triglyceride (MCT) oil Oxandrin (oxandrolone) solution vs. 01.mg/kg tablets in a small cohort of healthy adults. Participants will be dosed at two time points one week apart.
Primary Outcome Measures
NameTimeMethod
Peak Plasma Concentration (Cmax) curveMeasurement of Peak Plasma Concentration (Cmax) at 15 min, 30 min, 1, 2, 3, 4, 8, 24, 48 hours on Days 1 and 8

The primary outcome for this study will be the pharmacokinetics of a single dose of oxandrolone 0.1 mg/kg both in tablet form and in the MCT oil preparation as measured by peak plasma concentration (Cmax) curve

Area under the plasma concentration versus time curve (AUC)Measurements at 15 min, 30 min, 1, 2, 3, 4, 8, 24, 48 hours on Days 1 and 8

The primary outcome for this study will be the pharmacokinetics of a single dose of oxandrolone 0.1 mg/kg both in tablet form and in the MCT oil preparation as measured by the area under the plasma concentration versus time curve (AUC).

Secondary Outcome Measures
NameTimeMethod
Safety will be assessed by recording adverse events and assessment of hepatic function at baseline and one week following oxandrolone dosing.Liver function will be assessed by measuring serum transaminase levels at baseline and 1 week after each oxandrolone dose in the study participants, and any adverse events throughout the study period and up to 1 week after final dosing will be recorded.

The risks associated with the 2 doses of oxandrolone given during the course of this study are minimal. Known adverse effects of anabolic steroids, including hepatic dysfunction and virilization, are typically associated with longer-term use (months of daily dosing) and are very unlikely to occur in this study.
