Hi Jared,
You have clearly been through so much, and I can understand you thinking whether it is worth having a 5th line of treatment.
There are many immunotherapy treatments: bispecific antibodies such as elranatamab, teclistamab and talquetamab, the ADC treatment of belantamab and many others (not all approved in the UK such as CAR-T). For example, I am on Daratumumab, which is immunotherapy (though as a monotherapy, only really for patients in remission).
Therefore there is no one answer to side effects and sheer logistics (for example CAR-T is a ‘once and done’ treatment), even if everyone responded the same way to the same thing.
Do you know what your next treatment may be?
I won’t tell you blithely to carry on no matter what, this is a tough path that us patients go through. However, you may want to think calmly about the many options out there and the impact on those around you if you give up.
All the best, Jared.
Regards
Rabbit
