About this study

Participants who received a ADP adoptive cell therapy will be enrolled in this non-therapeutic, multi-center, long term follow-up (LTFU) study and will be followed for up to 15 years post-infusion of lentiviral vector-based adoptive cell therapy. Participants will be monitored for safety following last adoptive cell therapy infusion.

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • Participants who have received at least one dose of ADP adoptive cell therapy agent.
  • Participants who have completed ADP sponsored or supported interventional study or have withdrawn from it.
  • Participants who have completed treatment as part of managed access to a GSK adoptive cell therapy.
  • Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
  • The investigator is responsible for review of medical history.
  • Capable of giving signed informed consent.

Exclusion criteria

Treatment and study plan

ADP adoptive cell therapy

Biological

No study drug is administered in this study. Participants who received ADP adoptive cell therapy in a previous trial will be evaluated in this trial for long-term safety and efficacy.

Primary outcomes

  1. Number of participants with delayed adverse events (AEs) and serious adverse events (SAEs)

    Time frame: 15 years post last treatment

    AEs will be collected.

Secondary outcomes

  1. Number of participants with Vesicular Stomatitis Virus G protein (VSV-G) Deoxyribonucleic acid (DNA) copies in peripheral blood samples

    Time frame: 15 years

    Peripheral blood samples will be collected for the assessment of VSV-G DNA copies.

  2. Number of participants with Woodchuck hepatitis virus post-transcriptional regulatory element (WPRE) or Psi DNA copies in peripheral blood samples.

    Time frame: 15 years

    Peripheral blood samples will be collected for the assessment of WPRE or Psi DNA.

  3. Number of participants with integrated vector sequences and vector integration patterns identified in peripheral blood samples

    Time frame: 15 years

    Peripheral blood samples will be collected for the assessment of Integrated vector sequences and vector integration patterns (e.g., polyclonal, oligoclonal, or monoclonal).

  4. Number of deaths

    Time frame: 15 years

    Number of deaths will be summarized.

  5. Time to death

    Time frame: 15 years

    Time to death will be summarized.
