Outcome Measures
Adverse Events
Limitations and Caveats
The trial was terminated prematurely due to a slower than anticipated recruitment rate and a lower than anticipated observed CV event rate. Approximately 900 patients were planned to be included, however, at the time of stopping screening and recruitment 216 patients had completed the trial, 292 were ongoing, and 37 were withdrawn. The Sponsor decision to stop the trial was not based on any safety concerns, any knowledge of the results, or influenced by issues imposed by the COVID-19 pandemic.
More Information
