I really like this trial. They may have figured out why the vaccine wasn't working that well, and found a way around it. They tested it in dogs who had naturally occurring tumors and it worked pretty well. Now they are doing a clinical trial of the vaccine plus the CD200 checkpoint inhibitor in humans with recurrent glioblastoma . I will be watching this closely and wish them luck.
