Well, in DNDN's PROTECT trial, there 0 out of approx 120 pts in the Provenge plus Lupron arm had CVAs, while several out of approx 60 in the Lupron alone arm had CVAs.
Perhaps there will be something on the label to monitor for hypertension for the first year after Provenge, but I highly doubt there will be anything like a black-box warning. After all, a number of Taxotere pts had CVAs as well.
