Take part in our clinical study

If you or a loved one are experiencing memory loss, or
have been diagnosed with Mild Cognitive Impairment
(MCI or MCI-AD), Probable/Early Alzheimer’s disease,
or Mild-Moderate Alzheimer's disease, you or a loved one may be
eligible to participate in our clinical research study.



This clinical research study aims to evaluate an investigational drug in men and women with Alzheimer’s disease (AD). Currently, a limited number of approved treatments help with the symptoms of AD, but do not stop the disease from progressing. By reducing the build-up of ‘tau tangles’ in the brain, the main driver of AD, researchers believe that this investigational drug could help slow disease progression and enhance quality of life for people with AD.

Approximately 450 people in over 100 study centers across the United States, Canada, UK, France, Belgium, Italy, Spain and Poland are expected to take part in this study. The results will help determine whether this investigational drug can advance to the final stages of clinical development.

You or a loved one may be able to participate in the LUCIDITY study if you/they:

  • Are under 90 years of age

  • Are experiencing memory loss, or have been diagnosed with:

    • MCI (Mild Cognitive Impairment)/MCI-AD, or

    • Probable or Early Alzheimer’s disease, or

    • Mild-Moderate Alzheimer’s disease

  • Have a study partner who can assist with study participation

What Are Clinical Research Studies?

Clinical research studies are conducted to evaluate an investigational drug and determine how effective it is in treating a specific disease. These studies are performed according to strict governmental and ethical guidelines. Once these studies are completed, government agencies review the information then decide whether the drug should be made available for public use.

The 3 phases of clinical research studies

Phase 1

Phase 2

Phase 3

The drug being studied is given to a small group of healthy volunteers or patients. Researchers look to see how much is safe to take and how the human body responds when it receives the drug.

The drug is given to a small group of people with the target disease, or condition it is trying to treat. In this phase, researchers evaluate the right dose amount and begin to test the safety and effectiveness of the selected dose of the drug.

Researchers test the safety and effectiveness of the drug in a larger group of participants over a longer period of time, compared with Phase 2. Sometimes comparisons are made between the drug being studied and other medications that are already approved for the same purpose.

Some trials cover aspects from more than one phase. The LUCIDITY Study is in Phase 3. To learn more about this particular clinical research study, visit ClinicalTrials.gov.
