Meadow, I am so sorry your Father and family are going through this. For some immunotherapy has been effective but not all. It sounds like it is time for a talk with your fathers doctors about the best course forward for your father. They would know if your father would quality or benefit from any potentially avalible clinical trials. Another subject you should discuss is the advisability, timing and benefits of hospice. If needed it can offer help in pain control, other compfort measure and dignity.
As for drug reactions they can be unique to each individual so you also need to advise the prescribing physician.
I wish I could be of more help but know we are here listening if you need to talk.
