Hi Grandmat,
Thank you for explaining.
Lenalidomide is pretty standard maintenance chemotherapy now, and I think I am right in saying that it is the best in that role currently (or as researchers would put it, it is the ‘standard of care’), unless there is a specific reason otherwise for that patient. I am on it myself.
In terms of the trial, whether or not your husband is getting Ixazomib, my best guess is that he will be kept on the current maintenance until/unless either the side effects get too serious to continue with, or remission ends.
Regards
Rabbit
