Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Females, no child-bearing potential or negative urine pregnancy test on day of BAY94-9172 injection
* Exhibits visual, auditory, and communicative capabilities adequate to provide informed consent or assent and comply with study procedures
* Is willing and able to lie down in magnetic resonance imaging (MRI) and positron emission tomography (PET) scanners
* Is willing to donate their brain for postmortem examination in case of death
* The subject, or the subject and/or legally acceptable representative will be compliant and have a high probability of completing the study in the opinion of the investigator
* Has been fully informed about the study, including provisions of the Health Insurance Portability and Accountability Act (HIPAA), as applicable, and informed consent or assent has been signed and dated (with time) by the subject and/or the subject's legally acceptable representative
* The subjects who have participated in a previous florbetaben study e.g. study 311741 may be included in the present study. The MRI- and florbetaben PET scan do not need to be repeated if both scans were performed within twelve months prior to inclusion.
