What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to determine if it is possible to treat an infection with a cell-based immunotherapy (therapy that uses the patient's own immune system to treat the infection). This treatment is called adoptive T cell therapy. Another purpose is to learn about the side effects and toxicities of adoptive T cell therapy.Adoptive T cell therapy is an investigational (experimental) therapy that works by using the blood of a donor that has immunity against the virus. The donor cells are collected and then the cells, called T cells, that are capable of defending against the virus are selected out. These selected T cells are then infused back into the patient, to try to give the immune system the ability to fight the infection. Adoptive T cell therapy is experimental because it is not approved by the Food and Drug Administration (FDA).

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on high doses of certain steroids or have had specific treatments like antithymocyte globulin recently, you may not be eligible to participate.

Is adoptive T cell therapy generally safe for humans?

Adoptive T cell therapy has been used in clinical studies for treating various viral infections, including adenovirus, and has shown promise without causing significant tissue damage or harmful immune reactions in the central nervous system.12345

How is the treatment for adenovirus infections after bone marrow transplant unique?

This treatment uses specially prepared T cells from donors to help the patient's immune system fight adenovirus infections, which is different from standard antiviral drugs that often don't work well. The T cells are selected for their ability to target the virus specifically, making this a novel approach for patients with weakened immune systems after a bone marrow transplant.678910

What data supports the effectiveness of the treatment for adenovirus infections after bone marrow transplant?

Research shows that using virus-specific T cells, which are immune cells trained to target adenovirus, can help clear the virus in patients who have had a bone marrow transplant. In several studies, patients receiving these T cells showed a reduction in viral levels and improved recovery, indicating that this treatment can be effective in managing adenovirus infections.6891011

Are You a Good Fit for This Trial?

This trial is for patients who've had a bone marrow transplant at least 30 days ago and are struggling with adenovirus infections despite antiviral treatments, or can't tolerate such treatments. They should have an acceptable performance score indicating they're well enough to participate, be over 14 years old to consent, and use effective contraception.

What Are the Treatments Tested in This Trial?

Interventions

  • IFN-gamma-secreting HAdV antigen specific T cells
Trial Overview The study tests adoptive T cell therapy using donor immune cells (T cells) that fight the adenovirus. These T cells are infused into patients in hopes of boosting their ability to combat the infection. This experimental approach isn't FDA-approved yet.

Published Research Related to This Trial

Transferring a specific T-cell receptor (TCR) into γ/δ T cells allows them to effectively target and kill adenovirus-infected cells, providing a promising immunotherapy option for patients after allogeneic hematopoietic stem cell transplantation (HSCT).
This approach not only enhances the immune response against adenovirus but also minimizes the risk of graft-versus-host disease (GvHD) since γ/δ T cells are not allo-reactive, making it a safer alternative compared to traditional α/β T cells.
Human adenovirus-specific γ/δ and CD8+ T cells generated by T-cell receptor transfection to treat adenovirus infection after allogeneic stem cell transplantation.Dörrie, J., Krug, C., Hofmann, C., et al.[2022]
Adoptive transfer of virus-specific T cells from donors was successfully performed in nine children with systemic human adenovirus (HAdV) infection after stem cell transplantation, showing high specificity and reduced alloreactivity.
The treatment led to a successful immune response in five out of six evaluable patients, resulting in sustained expansion of HAdV-specific T cells and a significant reduction in viral copies, with the procedure being well tolerated overall.

Adoptive transfer of hexon-specific T cells, generated from donor mononuclear cells, shows promise as a treatment for adenovirus infections in patients post-hematopoietic stem cell transplantation, with over 72% of donors demonstrating a sufficient T-cell response.
The generated T cells exhibit strong cytotoxicity against adenovirus and good crossreactivity with different viral strains, indicating their potential effectiveness in restoring T-cell immunity against adenovirus infections.
