METHODS: This Phase 3 randomized, double-blind, placebo-controlled, 78-week study of ALZ-801 administered as 265 mg twice per day tablets, enrolled 50- to 80-year-old homozygotes with Mini-Mental State Examination (MMSE) ≥ 22 and Clinical Dementia Rating-Global Score 0.5 or 1.0.

The key secondary outcomes are Clinical Dementia Rating-Sum of Boxes and Instrumental Activities of Daily Living; volumetric magnetic resonance imaging and fluid biomarkers are additional outcomes.

RESULTS: The APOLLOE4 Phase 3 trial enrolled 325 subjects with a mean age of 69 years, 51% female, MMSE 25.6, and 65% mild cognitive impairment. Topline results are expected in 2024.

DISCUSSION: APOLLOE4 is the first disease-modification AD trial focused on
