If anyone is fighting CRC or is a caregiver, I highly recommend The Colon Club boards (https://coloncancersupport.colonclub.com/index.php). I was on the forum to discuss my mom's CRC, and there's a lot you can learn from there (such as side-effects, experiences, trials, insurance etc). Not to mention the emotional support and inspiring stories.
For trials, there's also https://trialfinder.fightcrc.org/ - created by Dr. Tom Marsilje (a cancer researcher) - who had an inspiring journey both as a patient and researcher.
