Clinical Trial Summary

To describe the rate of post-collection TU to testosterone conversion, as manifested by increases in testosterone concentration, in Plain tubes held at room temperature and sodium fluoride (NaF)-ethylenediaminetetraacetic acid (EDTA) tubes held at room temperature or on ice prior to centrifugation


Clinical Trial Description

This was an open-label, non-randomized, single-sequence study in which men dosed with JATENZO had blood drawn into 3 different types of blood-collection tubes (ie, Plain, EDTA, and NaF-EDTA). These tubes were then processed in different ways (ie, different durations between phlebotomy and centrifugation, different holding temperatures [room temperature or on ice] between phlebotomy and centrifugation). After defined periods of incubation, the tubes were centrifuged and the serum/plasma transferred into vials and frozen. The testosterone and TU levels in the serum/plasma were then measured using validated liquid chromatography/tandem mass spectrometry assays. ;
