Long-Term Follow-up Protocol for Subjects Treated with Gene-Modified T cells

Status: Active

Purpose / Objectives

Primary Outcome

  • To assess the risk of delayed adverse events (AEs) following exposure to GM T cells
  • To monitor for long-term persistence of GM T cells, including analysis of vector integration sites, as appropriate.
  • To monitor for generation of replication competent retroviruses (RCR)
  • To assess long-term efficacy following treatment with GM T cells
  • Describe growth, developmental outcome, and sexual maturity status for subjects who were aged < 18 years at time of GM T cell therapy
  • To assess long term health-related quality of life following treatment with GM T cells

Secondary Outcomes

  • Per Health Authority guidelines for gene therapy medicinal products that utilize integrating vectors (eg, retroviral vectors), long-term safety and efficacy follow up of treated subjects is required.
