简要总结

Investigators have previously used this sort of therapy to treat Hodgkin or non-Hodgkin lymphoma that is associated with the virus that causes infectious mononucleosis ("mono" or the "kissing disease"), Epstein-Barr virus (EBV). EBV is found in cancer cells of up to half of all patients with Hodgkin's and non-Hodgkin lymphoma. This suggests that it may play a role in causing lymphoma. The cancer cells infected by EBV are able to hide from the body's immune system and escape being killed. Investigators previously tested special white blood cells (cells that help the body fight disease and infection), called T cells. The T cells were trained to kill EBV-infected cells and were tested to see whether treatment with these cells could affect these tumors. In many patients investigators found that giving these trained T cells caused a complete or partial response.

However, many patients do not have EBV found in their lymphoma cells. Therefore, investigators now want to test whether special T lymphocytes directed against other types of proteins that show on the tumor cell surface can result in similar promising results. The proteins that will be targeted in this study are called tumor-associated antigens (TAAs) - these are cell proteins that are specific to the cancer cell, so they either do not show or show up in low quantities on normal human cells.

In this stage of the study, investigators will target five TAAs which commonly show on lymphoma cells , called NY-ESO-1, MAGEA4, PRAME, Survivin and SSX. Investigators will do this by using special types of T cells called cytotoxic T lymphocytes (CTLs) generated in the lab. These TM-specific T cells are an investigational product not yet approved by the U.S. Food and Drug Administration.

The purpose of this stage of the study is to find out if TM-specific cytotoxic T cells are safe in children. The investigators want to learn what the side-effects are, and to see whether this therapy might help treat patients who are considered high risk for relapse of Hodgkin disease or non-Hodgkin lymphoma.

详细描述

First, patients provide blood for us to make TAA-specific cytotoxic T cells in the lab. The amount of blood to be drawn will be less based on the child's weight per blood draw (3 mL/kg). Under certain conditions related to the patient's health, investigators may need to collect the blood using a process called apheresis. Apheresis is the process where blood is passed through a machine that separates out the components of the patient's blood that is needed. The remainder of the patient's blood is then returned to the patient's body.

If the TAA-specific cytotoxic T cells can be made, the time from collection of the blood to manufacture of T cells for administration to the patient is about 1 to 2 months.

The cells will then be injected by IV into the patient over 10 minutes. The patient may be pre-treated with acetaminophen (Tylenol) and diphenhydramine (Benadryl). Acetaminophen (Tylenol) and diphenhydramine (Benadryl) are given to prevent a possible allergic reaction to the T cell administration. Initially, two doses of T cells will be given two weeks apart. The patient's lymphoma will be assessed before the infusion (pre-infusion) and then 6 weeks after the second infusion. If after the patient's second infusion he/she has not relapsed or experienced a side effect which would prevent him/her from receiving any more cells, he/she can receive up to six (6) additional doses if they wish. The T cells would then be given at 6-8 week intervals.

In between the first and second T cell infusions and for 6 weeks after the last infusion, investigators ask that the patient not receive any other anti-cancer treatments such as radiation therapy or chemotherapy. If the patient does receive any other therapies in-between the first and second infusion of T cells, they will be taken off treatment and will not be able to receive the second infusion of T cells. All of the treatments will be given by the Center for Cell and Gene Therapy at Texas Children 's Hospital.

结局指标

主要结局

Treatment-related adverse event (tAE) Rate

时间窗: 8 weeks post first CTL infusion

Treatment-related adverse event (tAE) rate is the proportion of participants with tAE measured by the NCI Common Terminology Criteria for Adverse Events (CTCAE) v5.0. The tAE will be defined as development of Grade III-IV events in any organ system that do not return to grade I within 72 hours with the exception of events that are clearly unrelated, and, of hematological toxicities, which are only considered a tAE if Grade III persisting for up to 10 days or greater than or equal to Grade IV. In addition grade 2 or greater autoimmune reaction will be considered a tAE.

次要结局

  • Obtain information on the expansion, persistence and anti-tumor effects of the adoptively-transferred TAA-specific CTLs(8 weeks)
