All Clinical Trials for technetium tc-99m labeled carbon

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT01248221 ↗	Carbon-13 (13C)-Spirulina Platensis Gastric Emptying Breath Test (GEBT)	Completed	Advanced Breath Diagnostics, LLC	N/A	2010-12-01	The purpose of this study is to compare stomach emptying using 13C-Spirulina platensis breath test and scintigraphy in healthy subjects and subjects with dyspepsia. Subjects will eat a standard meal of 2 scrambled eggs, a slice of wheat toast and 8 ounces of skim milk. The eggs will be double labeled with Technetium-99m (99mTc) sulfur colloid and 13C-Spirulina platensis. Scintigraphy is a diagnostic technique in which a two-dimensional picture of internal body tissue is produced through the detection of radiation emitted by a radioactive substance administered into the body. The location of a standard meal in the digestive system will be measured by images of the 99mTc sulfur colloid taken at periodic intervals before and after the standard meal. The 99mTc Sulfur Colloid is approved by the FDA for use in medical diagnostic procedures. Spirulina platensis is blue - green algae, which is very similar to the naturally occurring spirulina sold in health food stores as a dietary supplement. The spirulina platensis has been labeled with the 13C stable isotope. 13C stable isotope labeling is inherently safe as 1.1% of all carbon in our bodies and in the food we eat is 13C. The presence of the 13C will be measured by breath samples at periodic intervals before and after a standard meal. The FDA considers 13C-Spirulina platensis to be investigational for the purposes of this study.
