Hi to everyone, my name is Santa I am a caregiver for my husband he is 67year old, we live in New Jersey he got diagnosed in August 2024, with Kappa light chain with high risk cytogenic TP53 abnormality and 1q gain. in June 2025 did stem cells transplant failed in one month. November 2025 did CAR T (Carvicty) it’s been 3 months and his Kappa light chain went from 17.1 mg in February and in March 308 mg. Anyone had a similar experience failed CART in 3 months? What medications you are taking? Any bad side affects? I just want some quality of life for my husband. I appreciate any advice. I feel like having a second opinion from another myeloma doctor.
