Someone just asked me about the vaccines I took for my cancer. Northwest Biotherapeutics appears to be close to doing a trial for prostate cancer involving over 300 patients. Not sure if they are giving the vaccines intratumorally or not but they have done that I am fairly sure in other trials. Nwbio.com
They were in Seattle but are now in Bethesda, Maryland. Might be worth looking into if someone has a progressing PSA that is not responding anymore.
