Hi Shanna,
Welcome to the site. Sorry that you had to find us all here and I am sorry also to hear about your mum. We have a clinical trial part of the website that may be of interest and use to you about all I think the trials that are available for CC patients. Perhaps doing some searching through will give you some idea of what is out there for trials. It can be found here –
http://cholangiocarcinoma.org/professionals/research/clinical-trials/
Also, please have a talk with your mums doctors, onc and medical team about possible trials and see what they say about things. I hope some of the info here on the site will be useful to you and please keep on coming back here as well. We are all here for you. Good luck with looking for trials and everything and please keep us updated on everything.
My best wishes to you and your mum,
Gavin
