Substudy of the Accuracy of Ingestible Event Marker (IEM) Detection by the Medical Information Device #1 (MIND1)

The OSMITTER study protocol was designed as a master protocol governing multiple substudies for the rapid assessment of candidate subcomponents for the MIND1 System. This substudy was conducted to determine the accuracy of IEM detection by the MIND1 System by completing a series of Patch applications and IEM ingestions in the clinic.
