Patterson didn't do the tropism test for Cytodyn. The presentations show tropism testing was done. The protocol explicitly lists tropism testing. Any DSMC would shut down the trial if a tropism test wasn't done. If you don't do tropism testing you'd have CXCR4/CCR5 patients mixed in with CCR5 patients and the statistical significance of your endpoint would be disastrous. One only has to look at our statistical significance to realize that's not the case.

Patterson knows that no CCR5 HIV trial would skip tropism testing because that would cause a failure of the endpoints. He also says that tropism tests are notoriously unreliable. Cytodyn relied on the most widely used tropism test out there and the newest version. With the newest version if I remember correctly it's well over 99% accurate. So the question now becomes, why is he trying to push that narrative.
