Summary

This trial is for patients who have had a stem cell transplant and have developed a viral infection that is not responding to standard therapy. In this trial, the patient will receive white blood cells that have been specially trained to fight the viral infection.

Who is the study for?

This trial is for patients who've had a stem cell transplant or CAR-T therapy and are struggling with persistent viral infections like EBV, CMV, adenovirus, or BK virus despite standard treatments. They should have partially HLA-matched T cells available and be able to taper off steroids. Pregnant women must test negative.

What is being tested?

The study tests the use of banked multivirus-specific T cells (VSTs) from donors to treat stubborn viral infections in patients post allogeneic hematopoietic stem cell transplant or CAR-T recipients. The VSTs are designed to fight specific viruses that cause severe complications when the immune system is weak.

What are the potential side effects?

Potential side effects aren't detailed but may include typical reactions related to immune therapies such as infusion-related symptoms, possible graft-versus-host disease (GVHD), and other immune-mediated responses.

Experimental Treatment

Group I: HLA-matched VSTsExperimental Treatment1 Intervention

Partially HLA-matched VSTs will be thawed and given by intravenous injection. Patients will receive 2 x 10\^7 or 4 x 10\^7 partially HLA-matched MVSTs, depending on their body surface area, as a single infusion. In the rare case where insufficient banked cell product is available, a lower number of cells may be infused with agreement of the principal investigator, patient and/or guardian and the treatment team Additional doses may be from the same donor or a different donor based on available cell lines and patient/disease factors. Decision to switch to a different donor can be made by the principal investigator based on factors that include sequential treatment of different viral infections, concerns for immune escape of the targeted virus and/or availability of a better matched or otherwise superior VST line. Additional treatments will only be given following the agreement of the patient, treating physician, and investigator. This process can be repeated as needed.

2Patient Review

Although this doctor is personable, I felt that they were very slow in addressing my concerns. I often had to wait a week or longer for answers or solutions, even when I was in discomfort.
