A Study of CNP520 Versus Placebo in Participants at Risk for the Onset of Clinical Symptoms of Alzheimer's Disease


Brief description of study

The purpose of this study is to determine the effects of CNP520 on cognition, global clinical status, and underlying AD pathology, as well as the safety of CNP520, in people at risk for the onset of clinical symptoms of AD based on their age, APOE genotype and elevated amyloid.

Detailed Study Description

The study uses a randomized, double-blind, placebo-controlled, parallel group, adaptive design with variable treatment duration in approximately 2000 cognitively unimpaired participants aged 60 to 75 years, with at least one APOE4 allele (Homozygotes or Heterozygotes) and, if Heterozygotes, with evidence of elevated brain amyloid.

The screening period is expected to last about 12 weeks. Participants will receive disclosure of their individual test results for APOE genotyping and brain amyloid status.

Treatment duration is variable (event driven trial) for at least 60 months, and up to an expected maximum of 84 months.

Participants will return to the study site every three months for drug dispensing and every six months for safety and efficacy assessments, including neuropsychological scales with input from the study partner. Brain MRI scans will be conducted at month 6 and month 12, and on a yearly basis thereafter.

The Follow-up visit will be scheduled 12 weeks after the end of the Treatment Epoch. An additional CSF and / or PET AD biomarker assessments will be conducted on a voluntary basis at year 2 and 5.

The study (also known as the Generation Study 2) is conducted as part of the Alzheimer's Prevention Initiative (API) program.
