Evaluating low and standard doses of Ticagrelor for heart patients after stent placement

A Randomized Non-inferiority Study of Low-dose and Standard-dose Ticagrelor After Intervention for Acute Coronary Syndrome

Phase 4 Interventional Shanghai Tong Ren Hospital · NCT04255602

This study is testing whether a lower or standard dose of Ticagrelor, along with Aspirin, can help heart patients in China who have had a stent placed to prevent serious heart and brain problems over the next year.

What this trial studies

This study evaluates the safety and efficacy of two different doses of Ticagrelor (60mg and 90mg) combined with Aspirin in preventing major cardiovascular and cerebrovascular events in patients who have undergone drug-eluting stent implantation for acute coronary syndrome. The trial focuses on Chinese patients and aims to determine which dosage is more effective over a one-year period following the intervention. Participants must be at least 18 years old and provide informed consent before the procedure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have successfully undergone percutaneous coronary intervention with drug-eluting stents for acute coronary syndrome.

Not a fit: Patients with active bleeding, known hypersensitivity to study medications, or significant non-cardiac co-morbid conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for preventing serious cardiovascular events in patients with acute coronary syndrome.

How similar studies have performed: Other studies have shown varying success with different antiplatelet therapies, but this specific comparison of Ticagrelor doses in this population is novel.
