Trial summary

Subjects who previously took part in an Adaptimmune study and received genetically changed T cells (including but not limited to MAGE-A10ᶜ⁷⁹⁶T and MAGE-A4ᶜ¹º³²T) are asked to take part in this long term follow-up study. Subjects will be asked to join this study once they complete the parent interventional study. Read more about this study

About this study

Official title: Long Term Follow-up of Subjects Exposed to Genetically Engineered Tumor Antigen Specific T Cell Receptors

Subjects who previously took part in an Adaptimmune study and received genetically changed T cells (including but not limited to MAGE-A10ᶜ⁷⁹⁶T and MAGE-A4ᶜ¹º³²T) are asked to take part in this long term follow-up study. Subjects will be asked to join this study once they complete the parent interventional study.

The purpose of this study is to find out if the genetically changed T cells that subjects received in the parent study have any long-term side effects. No additional study drug will be given, but subjects can receive other therapies for their cancer while they are being followed for long term safety in this study.

For a period of 15 years starting from last administration of the genetically changed T cells, subjects will visit their study doctor for a check-up and to have blood tests to look for any changes that might have happened because of the genetically changed T cells.

Read the detailed description

This is a non-therapeutic, multi-center, long-term follow-up (LTFU) study of subjects who have received lentivirus-mediated genetically engineered T Cell Receptors in an Adaptimmune sponsored clinical trial. The study is designed in accordance with FDA and EMA guidance on gene therapy trials.

The study involves up to 15 years post-infusion monitoring of subjects who have been exposed to lentivirus-mediated gene transfer in Adaptimmune clinical studies. The study will include subjects who have received various T cell receptors including but not limited to MAGE-A10ᶜ⁷⁹⁶T and MAGE-A4ᶜ¹º³²T. Subjects will undergo clinical evaluation (i.e., new medical history, physical exam, adverse events, and exposure to mutagenic agents, anti-cancer therapies and investigational products in other clinical studies) with careful attention to adverse events possibly related to gene transfer or lentivirus-induced diseases. Blood samples will be collected for evaluating persistence of cells with lentiviral vector sequences, the detection of replication competent lentivirus (RCL), and chemistry and hematology laboratory assessments. Subjects will be followed for survival.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of subjects with specific Long Term Follow-Up adverse events (AEs), including serious adverse events (SAEs) associated with administration of autologous T cell receptors that have been genetically modified by lentiviral vectors.

    • 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
    • Opportunistic and/or serious infections
    • Unanticipated illness and/or hospitalization deemed related to gene modified cell therapy

    Measured: 15 years post last treatment

Secondary outcomes (4)
  1. Measurement of Replication Competent Lentivirus (RCL) in genetically modified T cells

    Subjects' peripheral blood samples will be used to evaluate RCL

    Measured: 15 years post last treatment

  2. Persistence of genetically modified cells in the body

    Peripheral blood samples will be used to evaluate persistence

    Measured: 15 years post last treatment

  3. Assess the pattern of vector integration sites if at least 1% of cells in the surrogate sample are positive for vector sequences by PCR

    Number of samples positive for vector integration by PCR

    Measured: 15 years post last treatment

  4. Overall Survival (OS) post-infusion

    OS defined as the interval between the date of first T cell infusion and date of death due to any cause

    Measured: 15 years post last treatment

Questions about this trial

What is this clinical trial studying?

An observational study of Solid and Hematological Malignancies, run by Adaptimmune at 3 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 7 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: terminated after participants were enrolled). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of subjects with specific Long Term Follow-Up adverse events (AEs), including serious adverse events (SAEs) associated with administration of autologous T cell receptors that have been genetically modified by lentiviral vectors. (time frame: 15 years post last treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2021.
