I have recently lost a good friend in her 40s to multiple myeloma. It isn't named in this article, but would this treatment work for that cancer as well? Both seem to target B cells.
CAR therapy requires identifying a broadly expressed target; it looks like there are a few candidate antigens being evaluated for MM but I don't know if any of the studies have published significant results yet.
