Efficacy and Safety Study of Digital Cognitive Training and PCSK9 Inhibitor-Enhanced Lipid-lowering Strategy in Patients With Intracranial Atherosclerotic Stenosis: A 2×2 Randomized Controlled Trial
China420 participantsStarted 2026-05-25
Plain-language summary
This study aims to evaluate whether digital cognitive training and/or intensive lipid-lowering therapy with a PCSK9 inhibitor can improve cognitive function in patients with intracranial atherosclerosis (ICAS).
ICAS is a common cause of stroke and is also linked to thinking and memory problems. The study will enroll 420 adults aged 55-80 years who have 50-99% narrowing of an intracranial artery, subjective memory complaints, and LDL cholesterol ≥1.8 mmol/L, but who are not demented.
Participants will be randomly assigned to one of four groups in a 2×2 factorial design:
1. No cognitive training + standard statin therapy
2. Cognitive training + standard statin therapy
3. No cognitive training + intensive statin plus PCSK9 inhibitor
4. Cognitive training + intensive statin plus PCSK9 inhibitor
Cognitive training consists of 30 minutes of tablet-based exercises, 5 days per week for 12 weeks. The intensive lipid-lowering group receives a PCSK9 inhibitor (Recaticimab) injection at weeks 0, 4, and 12, on top of maximally tolerated statin.
The main outcome is change in a composite cognitive score from baseline to 24 weeks. Secondary outcomes include changes in specific cognitive domains, MRI markers of brain structure and function, and safety measures.
The study is multicenter, open-label with blinded outcome assessment, and is conducted under the approval of the ethics committee of Peking Union Medical College Hospital.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
