This study is designed to collect long-term safety and survival data from participants previously treated in an eligible Century-sponsored index trial. This is an observational study, and the elements of the study design allow for important follow-up for safety, survival, and the continued evaluation of any late adverse events (AEs) that may appear after treatment with such cellular products. Additionally, collection of persistence data from participants will support the identification of any long-term risks or late AEs that may be causally related to treatment with such cellular products.

Inclusion Criteria:

• Participants received at least one treatment with a cellular therapy product in an eligible index trial.
• Participant was withdrawn, early discontinued or completed an eligible index trial.
• Participant is willing and able to comply with scheduled visits, study plan, and other study procedures.
