As everyone heard, Pfizer announced preliminary results. As a safety requirement, clinical trials are required to periodically present interim data to an external oversight committee (I’ve posted about this committee before). This process is important in order to check futility. Basically, safety checks ensure that the study can complete what was promised and results are promising. If not, the trial will be stopped for the sake of participants. So, today’s announcement was routine. But (and this is important), the data are not published nor is the trial over.
