Ben,
So sorry to hear this. My sister was diagnosed with a GB in Jan. of this year. Had surgery to remove tumor, and after her last MRI it has grown back. We went to Northwestern Brain Institute yesterday. They have a clinical trial going on now that she will be entering soon. Go to their website and search for ongoing clinical trials. Also, the American Cancer Society has a wealth of info. You can get on a chat line with them. They have info on trials all over and can tell you if they are recruiting for them. My best to you.
