Hi there,
Hopefully someone will have experiences etc to share with you about this trial, although I have none. This is the trial here is it not?
https://clinicaltrials.gov/ct2/show/NCT02821754
Thought I would put a link to it on the boards as it may help people recognise it.
I did a search of the boards for the drugs used in the trial as thought that may be of help to you and came up with these links –
Tremelimumab –

Durvalumab –
https://cholangiocarcinoma.org/db/search/Durvalumab/
Hope some of that is of use and I keep my fingers crossed for your husband for the best possible outcome to the trial.
My best to you both,
Gavin
