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 infusion of GM T cells will be asked to enroll in this LTFU protocol upon either premature discontinuation from, or completion of the prior parent treatment protocol.
