Trial Identifier NCT03977584, BN40199

Condition Alzheimer Disease

Official Title Tau PET Longitudinal Substudy Associated With: A Double-Blind, Placebo-Controlled Parallel-Group Study in Preclinical PSEN1 E280A Mutation Carriers Randomized to Crenezumab or Placebo, and in Non-randomized, Placebo-treated Non-carriers From the Same Kindred, to Evaluate the Efficacy and Safety of Crenezumab in the Treatment of Autosomal-Dominant Alzheimer's Disease

Study Summary

This substudy will evaluate the effect of crenezumab on the longitudinal tau burden in a subgroup of preclinical Presenilin1 (PSEN1) E280A mutation carriers and non-carriers, who were enrolled in study NCT01998841 (GN28352). Participants will receive up to three intravenous (IV) injections of [^18F] Genentech Tau Probe 1 (GTP1) and will undergo a tau positron emission tomography (PET) scan after each IV injection of [18^F]GTP1. The purpose of this substudy is to increase the understanding of disease progression in the preclinical stage of familial Alzheimer's Disease (AD).

What is Clinical Research?

In clinical research, volunteers, researchers, and medical professionals work together toward a shared goal: better treatment outcomes for patients. Clinical trials are vital to their process. They are carefully designed and follow approved protocols.
