Summary
In this study, participants will be followed for up to 15 years after their last dose of WU-CART-007 for evaluation of delayed adverse events, presence of persisting WU-CART-007 vector sequences, and overall survival and progression-free survival.
No study drug will be administered in this study.
Participants will transition to this long-term follow up (LTFU) study when they meet the criteria for discontinuation from the main study or after completing 24 months of follow-up in the main study. Participants will be contacted every 6 months for the first 5 years following WU-CART-007 administration and then yearly, for up to 10 years.
