Brief Summary

XTR004 is a 18F-labeled myocardial perfusion positron emission tomography tracer use to measure myocardial perfusion and myocardial blood flow. XTR004 binds to the myocytes and targets respiratory chain complex 1 in the mitochondria.This phase I study investigated the safety, biodistribution, radiation dosimetry and Pharmacokinetics of XTR004 in 10 healthy Chinese adults volunteers.

Detailed Description

XTR004 is a 18F-labeled myocardial perfusion PET tracer, the first one developed in China by Sinotau Pharmaceutical Group. XTR004 targets and binds to the mitochondrial complex I protein. XTR004 reflects myocardial function at a molecular level. In pre-clinical studies XTR004 demonstrated high myocardial first-pass extraction and prolonged retention, allowing for early or delayed imaging. XTR004 can be clinically used to measure myocardial perfusion and myocardial blood flow. This Phase I study will be open-labeled, nonrandomized, single center study. Enrolled 10 healthy Chinese adults who meet all of the inclusion and none of the exclusion criteria. Subjects will receive 6-8 mCi of XTR004 via IV injection. Safety and tolerability will be observed. Biodistribution, pharmacokinetics, and dosimetry will be investigated.
