NCT Number: NCT05377307

Long-term Follow-up Study of Lentiviral-based Gene-edited Immune Cell Therapy

According to health authorities guidances (FDA 2006, EMA(European Medicines Agency) 2009) for gene therapy clinical trials, observing subjects for delayed adverse events for 15 years is recommended. This purpose of this long-term follow-up study is to evaluate the safety and efficacy in patients who have ever received lentiviral-based gene-edited immune cells which are manufactured by Pell Bio-Med Technology Co. Ltd.

Key information

About this study

After completion or early withdraw from the other treatment protocol, patients should be enrolled into this long-term follow-up study. If patients do not enter this study right after leaving the treatment protocol, they may have the option to enter this long-term follow-up study at any time within 15 years after the last lentiviral-based gene-edited immune cell infusion.

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • Patients must have ever received Pell's lentiviral-based gene-edited immune cell as monotherapy or as combination therapy in clinical trials.
  • The last lentiviral-based gene-edited immune cell infusion within 15 years.
  • Patient/patient's parent/legal guardian is capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.

Exclusion criteria

There are no specific exclusion criteria for this study.

Treatment and study plan

Pell's lentiviral-based gene-edited immune cell therapy

Genetic

No study drug or other planned treatment will be administered. Subjects who previously received Pell's lentiviral-based gene-edited immune cell therapy will be evaluated the safety and efficacy.

Primary outcomes

  1. To assess delayed adverse events which are suspected related to previous gene-edited immune cell therapy

    Time frame: 15 years

    • Proportion of patients with any events of the following items which are suspected related to previous gene-edited immune cell therapy.
    • New malignancies
    • New incidence or exacerbation of a pre-existing neurologic disorder
    • New incidence or exacerbation of a prior rheumatologic or other autoimmune disorder
    • New incidence of a hematologic disorder, including hypogammaglobulinemia
    • New incidence of infection (potentially product-related)
    • Other than the above adverse events, which are suspected related to gene-edited immune cell therapy judged by the investigator

Secondary outcomes

  1. Monitor for Replication Competent of Lentivirus (RCL)

    Time frame: 15 years

    Proportion of patients with detectable RCL in peripheral blood by VSV-G(Vesicular stomatitis virus G) qPCR

  2. Monitor the persistence of gene-edited immune cells in peripheral blood(By qPCR)

    Time frame: 15 years

    Proportion of patients with detectable transgene level in peripheral blood by qPCR

  3. Monitor the persistence of gene-edited immune cells in peripheral blood(By Flowcytometry)

    Time frame: 5 years

    Persistence of gene-edited immune cells in peripheral blood using flow cytometry

  4. To assess the long-term efficacy of gene-edited immune cells

    Time frame: 15 years

    • Proportion of patients with relapse or progress among patients who didn't progress or relapse at study entry/reentry
    • Incidence of death
