简要总结

The purpose of this study was to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of IONIS-MAPTRx in patients with Mild Alzheimer's Disease.

详细描述

This was a randomized, double-blind, placebo-controlled study in 46 participants, followed by an Open-Label Extension. This study consisted of two parts:

Part 1: a randomized, double-blind, placebo-controlled multiple ascending dose period in participants with Mild Alzheimer's Disease, followed by Part 2: the open-label, long-term extension period.

结局指标

主要结局

Part 1: Number of Participants With Adverse Events That Are Related to Treatment With ISIS 814907

时间窗: From first dose of study drug up to Week 37 in Part 1

An adverse event (AE) was defined as any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of medicinal (investigational) product, whether or not the AE was considered related to the medicinal (investigational) product. A TEAE was defined as any AE that starts or worsens on or after the date of first dose of study treatment. TEAEs were categorised as mild, moderate, and severe to aid in severity assessment.

Part 2: Number of Participants With Adverse Events That Are Related to Treatment With ISIS 814907

时间窗: From first dose of study drug up to Week 64 in Part 2

An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of medicinal (investigational) product, whether or not the AE was considered related to the medicinal (investigational) product. A TEAE was defined as any AE that starts or worsens on or after the date of first dose of study treatment. TEAEs were categorised as mild, moderate, and severe to aid in severity assessment.
