Brief summary

A Phase 2a study in men and women with early Alzheimer's disease to evaluate the pharmacodynamics, pharmacokinetics and safety of obicetrapib therapy.

Detailed description

This study will be a proof of concept, Phase 2a study in patients with early Alzheimer's disease (clinical diagnosis of Alzheimer's disease Stage 3 or 4 based on the National Institute on Aging Alzheimer's Association Research Framework criteria) to evaluate the Pharmacodynamic, cognitive effects, Pharmacokinetic, and safety and tolerability of obicetrapib therapy.

Small high-density lipoprotein (s-HDL) particle concentration plasma measured by Ion Mobility Assay. For more information on the measurement used please refer to this article: https://doi.org/10.1002/alz.12649

Time frame: baseline

Population: Due to a non-optimal sample preparation procedure, a number of the samples allocated for the small HDL-C particle analysis were lost and therefore no samples were assessed for this measure.
