Non Hodgkin Lymphoma Clinical Trial

Constitutive IL7R (C7R) Modified Banked Allogeneic CD30.CAR EBVSTS for CD30-Positive Lymphomas

Summary

This study involves patients that have a cancer called diffuse large B cell lymphoma (DLBCL), Natural killer/T-cell lymphoma (NKTL), or classical Hodgkin lymphoma (cHL) (hereafter referred to collectively as lymphoma). Patients' lymphoma has come back or not gone away after treatment.

A previous research study conducted at Baylor combined two ways of fighting disease: antibodies and T cells. Antibodies are proteins that bind to bacteria, viruses and other foreign substances to prevent them causing disease. T-cells are special infection-fighting white blood cells that can kill tumor cells or cells infected with bacteria and viruses. Both have shown promise treating cancer, but neither has been strong enough to cure most patients. In the previous study, an antibody called anti-CD30 which is found on the surface of some T-cells and cancer cells, and had been used to treat lymphoma with limited success, was joined to the T-cells through a process called gene transfer, resulting in CD30.CAR T cells.

Another study saw encouraging responses using CD30.CAR T cells made in a lab from a patients' own blood, before being injected back into the same patient to treat their lymphoma. These cells are termed 'autologous' because they are given back to the original patient. In another (ongoing) study patients were treated with allogeneic CD30.CAR T cells, which are made from healthy donors instead of the patients. The use of allogenic cells avoids a lengthy manufacture time since the products are stored as a bank and available on demand. This ongoing trial of allogeneic banked CD30.CAR-EBVSTs has preliminarily shown promising clinical activity with no safety concerns.

With the current study, we plan to extend the anti-cancer effects of the CD30.CAR T cell by attaching another molecule called C7R, which has made CAR T cells have deeper and longer anticancer effects in laboratory studies. We aim to study the safety and effectiveness of allogeneic banked CD30.CAR-EBVST cells that also carry the C7R molecule. Investigators will learn the side effects of C7R modified CD30.CAR-EBVST cells in patients and see whether this therapy may help lymphoma patients.

Full Description

This is a dose escalation study. This means that at the beginning, patients will be started on the lowest dose (1 of 4 different levels) of C7R.CD30.CAR-EBVST cells. Once the lower dose schedule proves safe, the next group of patients will be started at a higher dose. This process will continue until all 4 dose levels are studied. If the side effects are too severe, the dose will be lowered or the T cell infusion will be stopped. Both the risks and benefits of this study may be dose related. The investigators don't know the best dose that will provide benefit while minimizing the risks.

To enroll on this study, patients will need to have recovered from toxic effects of previous chemotherapy and not be receiving any other investigational agents. Patients cannot have received an investigational cell therapy or vaccine within the past 6 weeks. Patients cannot have received an investigational small molecule drug within the past 2 weeks.

If patients agree to take part in this study, the investigators will ask the patients to adhere to the following study visits and procedure. After patients have signed the consent form, patients are required to come to the hospital for a series of standard medical screening tests, lymphodepletion chemotherapy, infusion with CD30.CAR-EBVST cell treatment and follow-up visits (See details below).

Screening tests Screening tests include:

Blood tests [Human Leukocyte Antigen (HLA) testing] to help us identify the best match for patients from the banked CD30.CAR- EBVST cells.
Blood tests for viruses such as human immunodeficiency virus [HIV], human T cell lymphotropic virus [HTLV], hepatitis B virus and hepatitis C virus.
Tumor biopsy test to check the status of CD30.

Once the investigators find that patients are eligible for this study, patients will be called for additional screening tests before treatment day. The screening tests include:

Physical examination
Vital signs tests to measure temperature, pulse, respiratory rate and blood pressure
Blood tests to measure blood cells, kidney and liver functions
Urine test
Pregnancy test for women of child-bearing potential
Measurements of tumor by routine imaging studies

Lymphodepletion chemotherapy Several studies suggest that the infused T cells need room to be able to multiply and grow to accomplish their functions and that this may not happen if there are too many other T cells in the blood stream. Because of that, if patients have NOT had a bone marrow or stem cell transplant recently, patients will receive treatment with cyclophosphamide and fludarabine (chemotherapy drugs) before patients receive the C7R.CD30.CAR-EBVST cells if patient's doctor thinks this is appropriate. This is called "lymphodepletion".

These drugs will decrease the numbers of patients own T cells before the investigators inject the C7R.CD30.CAR-EBVST cells. Although the investigators do not expect any effect on the patients tumor with the dose that the patients will receive, these drugs are part of many regimens that are used to treat lymphoma.

Treatment with C7R.CD30.CAR-EBVST cells

Each patient will receive a total dose of CAR modified T cells as detailed below. Dose level cohorts will be numbered sequentially:

Dose Level 1: 4 × 10^7 C7R.CD30.CAR-EBVST cells
Dose Level 2: 1 × 10^8 C7R.CD30.CAR-EBVST cells
Dose Level 3: 4 × 10^8 C7R.CD30.CAR-EBVST cells
Dose Level 4: 8 × 10^8 C7R.CD30.CAR-EBVST cells

The C7R.CD30.CAR-EBVST cells will be infused via an IV line at the indicated dose. Before patients receive the infusion, they may be given a dose of acetaminophen or anti-histamine (Benadryl for example) to minimize any possible allergic reaction. The investigators will follow patients in the clinic after each infusion for up to 3 hours. The patient will need to stay less than 2 hours away from the Medical Center for 4 weeks after the C7R.CD30.CAR-EBVST cell infusion so the investigator can monitor them for side effects.

Follow-up visits

On follow-up visits after treatment, patients will also receive a series of standard medical tests:

Physical examination
Vital sign tests to measure temperature, pulse, respiratory rate and blood pressure
Blood tests to measure blood cells, kidney and liver functions
Urine tests (if clinically necessary)
Pregnancy test for women of child-bearing potential (if clinically necessary)
Measurements of tumor by routine imaging studies

After infusion of C7R.CD30.CAR-EBVST cells,the patients blood will be collected on follow-up visits at week 1, week 2, week 3, week 4, week 6, week 8, every 3 months for 1 year, every 6 months for 4 more years. After 15 years, in the event there is suspected or new cancer is detected, additional blood sample will also be collected for additional tests.

To learn more about the way the C7R.CD30.CAR-EBVST cells are working and how long they last in the body, the investigators will draw blood from a central line if participants have one.

The investigators will also look at any scans or biopsies patients have had as standard of care.
