10/5/20 was the date trial data was unblinded, followed in five months that NWBO realized they failed the primary endpoint and reported they were changing the protocol, endpoints, comparator and SAP. Then they took a whole year of data dredging to come up with a new treatment arm (rGBM) that was never in the original trial.
The OS data is still confounded -- most of the patients had multiple doses of DCVax-L while any external trial would have had well-controlled trials. But NWBO's was not. It is clear confounding that very likely skewed the trial results in their favor because of the extra dosing. It's not opinion it is fact -- the trial protocol, NWBO SEC filings reported it.
