Long-Term Follow-up Protocol for Participants Treated With Gene-Modified T Cells

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Received at least one gene-modified (GM) T-cell infusion in a previous Celgene sponsored, Juno Therapeutics, other affiliates of BMS, or Celgene alliance partner-sponsored trial, and have discontinued, or completed the post-treatment follow-up period in the parent treatment protocol, as applicable.
  • Must understand and voluntarily sign an Informed Consent Form/Informed Assent Form prior to any study-related assessments/procedures being conducted.

Exclusion criteria

Treatment and study plan

Gene-modified (GM) T cell therapy

Genetic

No investigational product will be administered

Primary outcomes

  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 cell drug products

    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. Proportion of participants who progressed on the study: participants with original diagnosis of malignancies

    Time frame: Up to 15 years from last GM T cells infusion

  8. Overall Survival (participants with original diagnosis of malignancies)

    Time frame: Up to 15 years from last GM T cells infusion

Secondary outcomes

  1. Lymphocyte count (B-cell)

    Time frame: Up to 15 years

    If B-cell recovery criteria are not met at Month 60 (Year 5), then annual monitoring will continue up to 15 years, until subject withdrawal of consent, or death, whichever occurs first.
