Comparing low dose and standard dose ticagrelor for heart patients with diabetes

A Randomized Controlled sTudy of Low Dose vs Standard Dose of tIcaGrelor on Platelet Function After intErvention for Acute Coronary syndRome in Diabetes Mellitus Patients

Phase 4 Interventional Shanghai Tong Ren Hospital · NCT04307511

This study is testing whether a lower dose of ticagrelor can work just as well as the standard dose for heart patients with diabetes who have had a procedure to open blocked arteries.

What this trial studies

This study aims to evaluate the effectiveness of a low dose of ticagrelor (60mg) compared to the standard dose (90mg) in patients with diabetes who have undergone percutaneous coronary intervention (PCI) for acute coronary syndrome. A total of 40 participants will be randomly assigned to receive either the low dose or standard dose of ticagrelor along with aspirin for a specified duration. The primary endpoints will focus on measuring platelet function using VASP and TEG methods at one and two months post-PCI, with clinical events monitored over a 12-month period.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 90 who have diabetes and have successfully undergone PCI for acute coronary syndrome.

Not a fit: Patients with active bleeding, known hypersensitivity to the 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 provide a safer and equally effective treatment option for patients with diabetes undergoing PCI.

How similar studies have performed: Other studies have explored similar dosing strategies for antiplatelet therapy, indicating potential for success in this approach.
