Trial Summary

What is the purpose of this trial?

This phase I trial studies the side effects of allogeneic adenovirus-specific cytotoxic T lymphocytes (donor T cell therapy) and to see how well they work in treating patients with a weakened immune system (immunocompromised) and adenovirus-related disease. Allogeneic adenovirus-specific cytotoxic T lymphocytes are made from donated blood cells grown in the laboratory and are designed to kill viruses that can cause infections in immunocompromised patients with adenovirus-related disease.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are on certain high doses of prednisone or have recently received specific treatments like anti-thymocyte globulin or donor lymphocyte infusion.

What data supports the effectiveness of the treatment Donor T Cell Therapy for adenovirus infections?

Research shows that using virus-specific T cells (VSTs) to treat adenovirus infections in patients who have had stem cell transplants is highly effective, with 81% of patients showing improvement and 58% achieving complete recovery. This approach is particularly beneficial for those with weakened immune systems, as traditional antiviral drugs often have limited success and can cause significant side effects.12345

Is Donor T Cell Therapy for Adenovirus Infections safe for humans?

Research indicates that Donor T Cell Therapy, also known as Virus-Specific T Cells (VSTs), is generally safe for treating adenovirus infections in humans, especially in those with weakened immune systems. Studies have shown that this therapy can effectively manage viral infections without significant acute toxicity or increased risk of graft-versus-host disease (a condition where donor cells attack the recipient's body).15678

How is Donor T Cell Therapy different from other treatments for adenovirus infections?

Donor T Cell Therapy is unique because it uses virus-specific T cells from a donor to help the patient's immune system fight adenovirus infections, especially in those with weakened immune systems after stem cell transplants. Unlike traditional antiviral drugs, which can have limited effectiveness and significant side effects, this therapy directly boosts the body's ability to target and eliminate the virus.12357

Treatment Details

Interventions

  • Donor T Cell Therapy (T-cell Therapy)
Trial OverviewThe study tests donor T cell therapy using allogeneic adenovirus-specific cytotoxic T lymphocytes (CTLs) in patients with weakened immune systems due to blood cancers. These CTLs are grown from donated cells aimed at fighting off adenovirus infections.

Findings from Research

In a phase 1/2 clinical trial involving 30 pediatric patients, ex vivo-generated virus-specific T cells (VSTs) demonstrated a high clinical response rate of 81% for treating adenoviral infections after hematopoietic stem cell transplantation, with 58% achieving complete response.
The study indicates that VSTs, whether derived from the stem cell donor or healthy third-party donors, are a safe and effective alternative to traditional antiviral treatments, which often have limited efficacy and significant side effects.

Adenoviruses are common but usually not dangerous for healthy individuals, while they can cause serious illness in immunocompromised patients, highlighting the need for effective treatments in these vulnerable groups.
The study suggests that using in vitro expanded virus-specific cytotoxic T lymphocytes (CTLs) could be a promising approach for treating or preventing adenovirus infections in immunosuppressed patients, as these T cells play a crucial role in controlling the virus in the body.

Adoptive transfer of donor-derived virus-specific T cells (VSTs) has shown effectiveness in restoring immunity against viral infections after hematopoietic stem cell transplantation (HSCT), with success rates of 70% to 90% in recipients.
Recent studies have also demonstrated that using closely matched third-party VSTs can provide protection, achieving response rates of 60% to 70%, which is crucial for patients with virus-naïve donors.

Adoptive immunotherapy using virus-specific cytotoxic T cells (CTLs) from seropositive donors can effectively prevent severe viral infections in immunocompromised patients after hematopoietic stem cell transplantation (HSCT) or solid organ transplantation (SOT) without significant toxicity or increased risk of graft-versus-host disease (GvHD).
The study highlights the potential of using partially HLA-matched virus-specific CTLs from healthy seropositive individuals as an alternative source for T-cell therapy, especially when donor blood is not available, and emphasizes the need for a third-party T-cell donor registry to enhance treatment options.

In a study involving 28 patients and 32 virus-specific T cell (VST) treatments over 3 years, the average yield of viable VSTs was 1.83 million cells, with a mean purity of 62.9%, indicating a robust method for generating these cells for antiviral therapy.
The research found that the frequency of VSTs in the donor's blood, particularly for cytomegalovirus (CMV), strongly predicts the quantity of VSTs in the final product, emphasizing the importance of careful donor selection in optimizing treatment outcomes.
