Ticagrelor and PLATO: Inaccuracies found in key studies for blockbuster heart drug ticagrelor (2025)
In a follow-up investigation into the multibillion-dollar drug ticagrelor, The BMJ has uncovered fresh concerns, this time in key platelet studies used in its FDA approval. For more than a decade, ticagrelor (Brilinta in the US and Brilique in Europe) has been recommended for patients with acute coronary syndrome—a range of conditions related to sudden reduced blood flow to the heart. Last December, an investigation by The BMJ found serious data integrity problems in the landmark clinical trial (PLATO) that was used to gain worldwide approval for ticagrelor, calling into question the drug's advantage over cheaper rivals. Now, as generic versions of the drug prepare to launch this year, The BMJ has expanded its investigation, looking at two key platelet studies that AstraZeneca claimed explained ticagrelor's ability to treat acute coronary syndrome successfully. It finds that the "primary endpoint" results (the trial's key measurement) for both clinical tri...
