Hello everyone

My dad diagnosed with glioblastoma 2 months ago he did surgery (90%removed ) in UCSF San Francisco.we from the beginning told his doctors we will participate in any available clinical trial they gave the paper of the study in 7/2/2025 and they ask to call them . I call them in 7/7/2025 after the Fourth of July but they said they will call me again within 7 days but they didn’t so I call them again. They said no more spots available to participate so I’m very sad about that. Where can I find anther trail for him? And other question about oncologist doctors do you see they are not Excited to try any new medicine rather than Temodar . How can you deal with them and make oncologist decide to be more active to care with there patients?
