Description:
Patients have a type of cancer called NHL, Multiple Myeloma (MM) or CLL that has come back or
has not gone away after treatment. There is no standard treatment for the cancer at this time
or the currently used treatments do not work completely in all cases like these. This is a
gene transfer research study using special immune cells.
The body has different ways of fighting infection and disease. No single way seems perfect
for fighting cancers. This research study combines two different ways of fighting disease,
antibodies and T cells, that investigators hope will work together. Antibodies are types of
proteins that protect the body from bacterial and other diseases. T cells, also called T
lymphocytes, are special infection-fighting blood cells that can kill other cells, including
tumor cells. Both antibodies and T cells have been used to treat patients with cancers; they
have shown promise, but have not been strong enough to cure most patients.
The antibody used in this study recognizes a protein on the lymphoma, MM or CLL cells called
kappa immunoglobulin. Antibodies can stick to lymphoma, MM or CLL cells when it recognizes
the kappa molecules present on the tumor cells. For this study, the kappa antibody has been
changed so that instead of floating free in the blood it is now joined to the T cells. When
an antibody is joined to a T cell in this way it is called a chimeric receptor. These
chimeric receptor-T cells seem to kill some of the tumor, but they don't last very long and
so their chances of fighting the cancer are limited.
In the laboratory, investigators found that T cells work better if they also add a protein
that stimulates T cells to grow called CD28. By joining the anti-kappa antibody to the T
cells and adding the CD28, the investigators expect to be able to make cells that will last
for a longer time in the body (because of the presence of the CD28). They are hoping this
will make the cells work better.
Previously, when patients enrolled on this study, they were assigned to one of three
different doses of the kappa-CD28 T cells. We found that all three dose levels are safe. Now,
the plan is to give patients the highest dose that we tested.
These chimeric T cells (kappa-CD28) are an investigational product not approved by the FDA.

Purpose
Patients have a type of cancer called NHL, Multiple Myeloma (MM) or CLL that has come back or
has not gone away after treatment. There is no standard treatment for the cancer at this time
or the currently used treatments do not work completely in all cases like these. This is a
gene transfer research study using special immune cells.
The body has different ways of fighting infection and disease. No single way seems perfect

proteins that protect the body from bacterial and other diseases. T cells, also called T

have shown promise, but have not been strong enough to cure most patients.
The antibody used in this study recognizes a protein on the lymphoma, MM or CLL cells called
kappa immunoglobulin. Antibodies can stick to lymphoma, MM or CLL cells when it recognizes
the kappa molecules present on the tumor cells. For this study, the kappa antibody has been
changed so that instead of floating free in the blood it is now joined to the T cells. When

will make the cells work better.
Previously, when patients enrolled on this study, they were assigned to one of three
different doses of the kappa-CD28 T cells. We found that all three dose levels are safe. Now,
the plan is to give patients the highest dose that we tested.
These chimeric T cells (kappa-CD28) are an investigational product not approved by the FDA.
Detailed Description
To prepare the lymphoma, MM or CLL specific T cells investigators will take 240 ml (up to 16
tablespoonfuls)of blood from the patient. This would be drawn as 2 (two) separate blood
collections of 120 ml (up to 8 tablespoonfuls) of blood.
To get the kappa antibody (with CD28) to attach to the surface of the T cell, investigators
inserted the antibody gene into the T cell. This is done with a virus called a retrovirus
that has been made for this study and will carry the antibody gene into the T cell. This
virus also helps investigators find the T cells in the patient's blood after they're
injected. Because the patient has received cells with a new gene in them patients will be
followed for a total of 15 years to see if there are any long term side effects of gene
transfer.
Several studies suggest that the infused T cells need room to be able to grow and accomplish
their functions and that this may not happen if there are too many other T cells in
circulation. Because of that, if the level of circulating T cells is relatively high or the
patient has B-CLL, the patient may receive treatment with cyclophosphamide and fludarabine
(Cy and Flu) prior to the infusion of the T cells. This drug will decrease the numbers of the
patients own T cells before infusion of the kappa-CD28 T cells. Although investigators don't
expect any effect on the tumor with the dose that the patient will receive, this drug is part
of many regimens that are used to treat lymphoma, MM or CLL. If you are already receiving
chemotherapy, this may not be needed.
Patients will be given an injection of cells into the vein through an IV line. If s/he
receives Cy and Flu as stated above, the T cells will be given no sooner than 24 hours
afterwards. If the patient has recently received other chemotherapy, the T cells will be
given at least 24 hours after their last chemotherapy. The injection will take about 20
minutes. Investigators will follow the patient in the clinic after the injection. The
treatment will be given by the Center for Cell and Gene Therapy at Texas Children's Hospital
or Houston Methodist Hospital.
If after a 4-6 week evaluation period after the infusion, the patient seems to be
experiencing a benefit (confirmed by radiological studies, physical exam and/or symptoms),
the patient may be able to receive additional doses of the T cells if they wish. These
additional infusions would be at least 4-6 weeks apart and at the same dose level they
received the first time or a lower dose. If the patient's circulating T cells are relatively
high prior to any additional doses of T cells, they may receive Cy and Flu beforehand.
