Phase III Study of Intravenous Trontinemab for Treating Early Symptomatic Alzheimers Disease from Mild Cognitive Impairment to Mild Dementia

What this Trial Is About

Researchers are evaluating the efficacy and safety of trontinemab in people with early symptomatic Alzheimers disease, ranging from mild cognitive impairment to mild dementia due to Alzheimers. This Phase III study aims to better understand the impact of trontinemab on cognitive decline and daily functioning in this population. The study is randomized, double-blind, and placebo-controlled to ensure reliable results. Participants will be assigned to receive either intravenous trontinemab or an intravenous placebo. The treatment period lasts up to 72 weeks, during which participants receive infusions as scheduled. Assessments include brain imaging such as amyloid and tau PET scans, cerebrospinal fluid and blood biomarker collection, and cognitive testing. The study also monitors safety through tracking adverse events, infusion-related reactions, and anti-drug antibodies. Participants will attend visits for evaluations including clinical dementia rating, cognitive scales like MMSE and ADAS-Cog-13, and daily living activities assessments. Safety monitoring involves MRI scans and lab tests. The primary outcome measured is the change in Clinical Dementia Rating, Sum of Boxes CDR-SB, from baseline to Week 72. The total duration of participation extends through the 72-week treatment and assessment period, with ongoing safety evaluations.
