Brief Summary:

This is a prospective study for the long-term follow-up (LTFU) of safety and efficacy for all pediatric and adult participants exposed to Gene-modified (GM) T cell therapy participating in a previous Celgene sponsored or Celgene alliance partner sponsored study.

Participants who received at least one GM T cell infusion will be asked to enroll in this LTFU protocol upon either premature discontinuation from, or completion of the prior parent treatment protocol.

Primary Outcome Measures :
  1. Incidence of delayed Adverse Events (AEs) [ Time Frame: Up to 15 years from last gene-modified (GM) T cell infusion ]
  2. Persistence of GM T cells [ Time Frame: Up to 15 years from last GM T cell infusion ]
  3. Analysis of vector integration sites [ Time Frame: Up to 15 years from last GM T cell infusion ]
  4. Incidence of replication-competent lentiviruses [ Time Frame: Up to 15 years from last GM T cell infusion ]
  5. Physical growth as assessed by physical examination (pediatric participants only) [ Time Frame: Up to 15 years from last GM T cells infusion or until Tanner Stage 5 is reached ]
  6. Incidence of sexual maturation as assessed by the Tanner staging system (pediatric participants only) [ Time Frame: Up to 15 years from last GM T cells infusion or until Tanner Stage 5 ]
  7. Disease status of the primary malignancy [ Time Frame: Up to 15 years from last GM T cell infusion ]
  8. Disease Progression: Number of participants who continue to be responders, who have progressed, and who have relapsed will be reported. [ Time Frame: Up to 15 years from last GM T cells infusion ]
  9. Disease Relapse: Number of participants who continue to be responders, who have progressed, and who have relapsed will be reported. [ Time Frame: Up to 15 years from last GM T cells infusion ]
  10. Overall Survival defined as the time from the first dose of investigational product or from the randomization date to the date of death or the date the participant is last known to be alive. [ Time Frame: Up to 15 years from last GM T cells infusion ]

Secondary Outcome Measures :
  1. Health-related quality of life (HRQoL): Measurement of HRQoL changes as assessed using instruments administered in the parent treatment protocol [ Time Frame: Up to approximately 5 years from last GM T cell infusion ]
