Dominantly Inherited Alzheimer Network Trial Unit (DIAN-TU)

Start: December 2012
End: October 2027
Enrollment: 490

What Is This Study About?

This ongoing study is testing the safety and effectiveness of several experimental drugs to slow the progression of cognitive impairment in people with an inherited Alzheimer's disease-causing gene mutation. Specifically, mutations in presenilin 1 (PSEN1), presenilin 2 (PSEN2), and amyloid precursor protein (APP) genes are associated with inherited Alzheimer's disease. All participants will be tested to determine if they have one of the mutations. Participants found to have one of the mutations will be randomly assigned to receive injections of one of the study drugs. Those participants who do not have a mutation will be randomly assigned to receive injections of either a study drug or a placebo. Injections will be given every four weeks for up to 208 weeks. Researchers will measure changes in cognition, blood and spinal fluid biomarkers, abnormal amyloid and tau protein in the brain, and brain glucose metabolism. Measurements will be done at the start of the study and then again at weeks 52, 104, 156, and 208. The study, called DIAN-TU, will test several different study drugs, starting with gantenerumab and solanezumab.
