Trial summary

WT1 TCR gene therapy is a new treatment for acute myeloid leukaemia and chronic myeloid leukaemia. Patient's white blood cells (T cells) are modified to specifically fight the leukaemia cells by transferring a gene into the T cells, which allows them to recognize fragments of a protein called WT1.

About this study

WT1 TCR gene therapy is a new treatment for acute myeloid leukaemia and chronic myeloid leukaemia.

Patient's white blood cells (T cells) are modified to specifically fight the leukaemia cells by transferring a gene into the T cells, which allows them to recognize fragments of a protein called WT1. This protein is present on the surface of leukaemia cells at very high levels. The gene transferred to the T cells enables them to make a new T cell receptor (TCR), which will allow them to attack leukaemia cells with high levels of WT1 on their surface.

Using this form of gene therapy the investigators can convert some of the patient's immune system's own T cells into T cells that the investigators hope will be much more effective at recognizing and killing leukaemia cells.

Read the detailed description

This trial concerns a novel approach to generating leukaemia antigen-specific T cells for adoptive cellular therapy in HLA-A*0201 patients with acute myeloid leukaemia (AML) and chronic myeloid leukaemia (CML)

In this study, patient T cells will be gene-modified using a GMP grade retroviral vector containing the genes for a WT1-specific, HLA-A2-restricted T cell receptor. This ex vivo gene therapy will generate T cells expressing the WT1-specific TCR and thus able to recognise WT1-expressing target cells.

The autologous Cys1 WT1 TCR-transduced T cells will be re-infused back into adult leukaemia patients following lymphodepleting conditioning.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing WT1 TCR-transduced T cells in people with Acute Myeloid Leukaemia and Chronic Myeloid Leukaemia, run by Cell Medica Ltd at 2 sites in United Kingdom.

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 0 inclusion and 11 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: finished, as of the sponsor's last update on 2 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Identify organ toxicities and other side effects (time frame: Up to 12 months per patient). The study lists 2 primary outcomes in all. 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 2 Oct 2018.
