Dominantly Inherited Alzheimer Network Trial: An Opportunity to Prevent Dementia. A Study of Potential Disease Modifying Treatments in Individuals at Risk for or With a Type of Early Onset Alzheimer's Disease Caused by a Genetic Mutation. (DIAN-TU)

The purpose of this study is to assess the safety, tolerability, biomarker and cognitive efficacy of gantenerumab and solanezumab in subjects who are known to have an Alzheimer's disease-causing mutation by determining if treatment with the study drug improves cognitive outcomes and disease-related biomarkers.

Inclusion Criteria:

• Between 18-80 years of age
• Individuals who know they have an Alzheimer's disease-causing mutation or are unaware of their genetic status and have a 50% chance of having an autosomal dominant Alzheimer's disease (ADAD) mutation (e.g. parent or sibling with a known AD-causing mutation)
• Are within -15 to + 10 years of the predicted or actual age of cognitive symptom onset
• Cognitively normal or with mild cognitive impairment or mild dementia, Clinical Dementia Rating (CDR) of 0-1 (inclusive)
• Able to undergo Magnetic Resonance Imaging (MRI), Lumbar Puncture (LP), Positron Emission Tomography (PET), and complete all study related testing and evaluations.
• For women of childbearing potential, if partner is not sterilized, subject must agree to use effective contraceptive measures (hormonal contraception, intra-uterine device, sexual abstinence, barrier method with spermicide).
• Adequate visual and auditory abilities to perform all aspects of the cognitive and functional assessments.
• Has a Study Partner who in the investigator's judgment is able to provide accurate information as to the subject's cognitive and functional abilities, who agrees to provide information at the study visits which require informant input for scale completion.

Exclusion Criteria:

• History or presence of brain MRI scans indicative of any other significant abnormality
• Presence of pacemakers, aneurysm clips, artificial heart valves, ear implants, or foreign metal objects in the eyes, skin or body which would preclude MRI scan.
• History or presence of clinically significant cardiovascular disease, hepatic/renal disorders, infectious disease or immune disorder, or metabolic/endocrine disorders
• Anticoagulants except low dose (≤ 325 mg) aspirin.
• Have been exposed to a monoclonal antibody targeting beta amyloid peptide within the past six months.
• History of cancer within the last 5 years, except basal cell carcinoma, non-squamous skin carcinoma, prostate cancer or carcinoma in situ with no significant progression over the past 2 years.
• Positive urine or serum pregnancy test or plans or desires to become pregnant during the course of the trial.
• Subjects unable to complete all study related testing, including implanted metal that cannot be removed for MRI scanning, required anticoagulation and pregnancy.
