P-BCMA-ALLO1, an allogenic CAR-T targeting BCMA for relapsed/refractory multiple myeloma (RRMM), is manufactured using the piggyBac® DNA Delivery System and the Cas-CLOVERTM gene editing system, which eliminates TCR expression and reduces MHC class I expression to prevent GvHD. Here, TNFRSF17 is linked to AL amyloidosis.
