They could not stop the trial without the data. They typically remove the placebo arm. There was a great discussion between a patient advocacy group and an eminent oncology doctor from the Mayo, as I recall, and I used to post that clip, which they took down, or moved. In it he explains that placebo patients will get the best current care, and their safety is evaluated just like the other patients. He indicated, as I recall, if during monitoring it is determined that placebo arm patients are disadvantaged, they receive access to the drug, but the trial will continue blinded to preserve the data.
It’s unfortunate that it’s gone.
