The primary objective of this study is to evaluate the long-term safety of P-BCMA-101.
Secondary objectives of this study are to evaluate:
- The persistence of anti-tumor effect of P-BCMA-101 and its relationship to persistence of P-BCMA-101 cells, BCMA tumor surface expression and circulating BCMA
- The persistence of the P-BCMA-101 cells
- Evaluate the safety and effect of rimiducid on P-BCMA-101- related adverse events (AEs) if indicated
