Tiny study asks: does aspirin work in patients with low platelets?
NCT ID NCT04912505
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how well a daily low-dose aspirin works in people who have both immune thrombocytopenia (low platelets) and heart disease. Only 4 adults took part. Researchers measured platelet function after aspirin to see if the standard dose is enough to prevent blood clots. The study is complete, but the small size means the findings are very limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Aspirin
- What this could lead to
- If successful, this could help doctors understand if standard aspirin dosing is enough to protect against blood clots in people with immune thrombocytopenia.
- What could go wrong
- This was a very small, early-phase study with only 4 participants, so results may not apply to everyone. The study is already completed, and no new treatment is being tested.
