Welcome to the recruiting website for the Radiant study, a clinical research study of an investigational drug for people with hallucinations (sensing something or someone that is not there) and/or delusions (clearly false beliefs that the person believes are real) associated with Alzheimer’s disease.

If someone you care for is experiencing these common symptoms, please continue reading to see if our study might be an option.

Right now, we are looking for people ages 55 to 95 who are living with Alzheimer’s disease and have experienced delusions or hallucinations for at least 2 months.

In this study, we will be evaluating an investigational drug in two doses against a placebo (an inactive substance that looks like the investigational drug). Those who complete the study may have the option to enter an open-label long-term extension study, in which all participants receive the active study drug and are told at which dose.

To see if the person you care for may qualify to participate in our study, please take our pre-qualification questionnaire. If you prequalify on the questionnaire, you will have the option to submit your contact information to the nearest participating study center. If you submit your information, the study center staff will contact you for additional information. Based on this information, you and the person you care for may be asked to come to the study center to undergo additional assessments to determine whether they are eligible for the study. You and the person you care for are not obligated to participate in the study at any point in the process.
