T-Lymphocytes for Prevention or Treatment of Viral Infections Following Hematopoietic Stem Cell Transplantation

United States32 participantsStarted 2017-02-15

Plain-language summary

This Phase I dose-escalation trial is designed to evaluate the safety of rapidly generated multivirus-specific T-cell products with antiviral activity against CMV, EBV, adenovirus, HHV6, BK virus, JC virus, and human parainfluenza-3 (HPIV3), derived from eligible HSCT donors. In this trial, we will utilize a rapid generation protocol for broad spectrum multivirus-specific T cells for infusion to recipients of allogeneic hematopoietic stem cell transplant (HSCT), who are at risk of developing EBV, CMV, adenovirus, HHV6, BKV, JCV and/or HPIV3, or with PCR/culture confirmed active infection(s) of EBV, CMV, adenovirus, HHV6, BKV, JCV, and/or HPIV3 that has failed to resolve with at least 14 days of standard antiviral therapy (if available and tolerated). These cells will be derived from HSCT donors, and the study agent will be assessed at each dose for evidence of dose-limiting toxicities (DLT). This study will have two arms: Arm A will include patients who receive prophylactic treatment, and Arm B will include patients who receive VSTs for one or more active infections with targeted viruses. Determination of the study arm will be determined by the patient's clinical status. Study arms will each be analyzed for safety endpoints and secondary endpoints.

Inclusion criteria

. Prior myeloablative or non-myeloablative allogeneic hematopoietic stem cell transplant using either bone marrow or peripheral blood stem cells no earlier than 5 days prior to the date of VST infusion. VSTs administered as:
. Prophylaxis for patients at risk of EBV, CMV, adenovirus, HHV6, BKV, JCV and/or HPIV3.
. Treatment of reactivation or active infection(s) with EBV, CMV, adenovirus, HHV6, BKV, JCV, and/or HPIV3 that has failed to resolve with at least 14 days of standard antiviral therapy (if available and tolerated). Patients with multiple infections due to the targeted viruses are also eligible.
. Clinical status at infusion allows for tapering of steroids to less than 0.5 mg/kg/day prednisone or equivalent. 3) Karnofsky/Lansky score of ≥ 50.

Exclusion criteria

. Patients with other uncontrolled infections.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
