Who could benefit from this research

Could help

Adults in sub-Saharan Africa who have survived a stroke and are candidates for secondary prevention.

Less likely to help

Patients who cannot take cilostazol due to contraindications or who are in regions without access to necessary follow-up care may not benefit.

What this research studies

The project aims to show that cilostazol, taken twice daily, safely reduces the risk of another stroke in African patients who have already had one. It uses a hybrid study design to assess efficacy and safety in a low-resource setting while building local stroke research capacity. The study will involve active follow-up of participants and monitoring for adverse events, with a focus on affordability and applicability in sub-Saharan Africa. If successful, the findings could inform guidelines and improve long-term outcomes for stroke survivors in the region.

Why it matters

Potential benefit: If successful, patients could experience fewer recurrent strokes and better long-term survival in a resource-limited setting.

How similar studies have gone: Previous studies in Asian populations showed reduced major cardiovascular events with cilostazol added to antiplatelet therapy, but data in African populations are limited.
