Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
The study was conducted at two sites in the US.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 130 subjects were screened. 21 subjects were considered as screen failures and were not enrolled into the study. 9 subjects did not meet the inclusion/exclusion criteria. 10 subjects withdrew their consent. 1 subject was lost to follow-up and 1 subjected exceeded the weight limit for the camera.

Reporting Groups
Down Syndrome Group 39 Down Syndrome subjects received Florbetaben (BAY94-9172) : 300 megabecquerels (MBq) single IV injection of 2 to 10 mL
Healthy Volunteer Group 70 healthy volunteer subjects received Florbetaben (BAY94-9172): 300 MBq single IV injection of 2 to 10 mL
