Thanks for your contributions DocLogic, I remember the talks about DCVax Lung What makes sense is that improvements were made to DCVax throughout the trial. Thats why we had to wait so long. As Linda Liau said ... we are comparing earlier trial enrollees to later enrolles. Everybody is living longer than expected. I expect to see a comparision between early recipients and later reciepients because improvements were made to drug durring the trial.
