We built our state of the art 30 bed facility with the security and comfort of our research participants in mind. This includes various amenities, such as an exercise area and an entertainment room with internet access. Our residents will enjoy nutritious and well-balanced meals provided by a local catering company.

Apart from these, we also provide free parking and free transportation for all our research participants.

Patient Safety Monitoring

We conduct all of our clinical studies in strict accordance with protocols reviewed by the FDA along with an Institutional Review Board representing public interest. For example, when conducting a memory loss test in St. Louis or other research studies, progress is closely monitored by each of these agencies. Participants are evaluated frequently throughout the course of the study to document effectiveness and safety of the medication. Test subjects may withdraw from the study at any time, or be withdrawn, should the investigator feel that it is in their best interest to do so.

About Clinical Trials

Researchers spend an extensive amount of money and time looking for new methods in diagnosing and treating illnesses and diseases every year.

Before we approve any new medication, these medications undergo a series of lengthy and rigorous tests. Not only do medications have to be safe and effective, but they also must demonstrate a superior benefit when compared to other drugs that have similar effects. This strict adherence to quality makes St. Louis Clinical Trials the leading research agency on dementia and other memory conditions in the St. Louis area.
