Alzheimer's Tau Platform: Testing Tau-Directed Therapies

This study, called the Alzheimer's Tau Platform (ATP), is testing new treatments for early Alzheimer's disease. Researchers want to see if drugs like AADvac1 and Tau2, which target a protein called tau, can reduce tau buildup in the brain. They are also looking at these drugs in combination with donanemab, an antibody that targets another protein called amyloid. You might be able to join if you are between 50 and 80 years old and have early signs of Alzheimer's disease. The main goal is to see if these treatments can reduce tau in the brain, measured over 30 months using special brain scans (PET scans). This study is designed to test several treatments at once or one after another.

Study design
This is an interventional study with a planned enrollment of 900 participants. It's a platform trial, meaning multiple investigational products will be tested simultaneously or sequentially.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Tau deposition in the brain will be measured at 0, 6, 18, and 30 months.

  • Reduction of brain tau deposition as measured by tau positron emission tomography (PET)0, 6, 18 and 30 months

    To determine whether at least one tau therapy, either alone or in combination with donanemab, will produce a greater reduction in brain tau deposition as measured by 18F-MK-6240 PET compared to donanemab alone.
