Phase I/II Study of Metastatic Melanoma Using Lymphodepleting Conditioning Followed by Infusion of Tumor Infiltrating Lymphocytes Genetically Engineered to Express IL-12
Background:
- One experimental treatment for certain types of cancer is cell therapy, which involves
collecting lymphocytes (white blood cells) from a tumor, growing them in the laboratory in
large numbers, and then modifying the cells with a gene (interleukin-12 (IL-12)) that
stimulates the immune system to attack and destroy the cancer cells. Because this treatment
is experimental, researchers are interested in determining the side effects and overall
effectiveness of cell therapy using white blood cells modified with IL-12 as a treatment for
aggressive cancer.
Objectives:
- To determine the safety and effectiveness of cell therapy using IL-12 modified tumor white
blood cells to treat metastatic melanoma.
Eligibility:
- Individuals greater than or equal to 18 years of age and less than or equal to age 66 who
have been diagnosed with metastatic melanoma.
Design:
- Participants will be screened with a medical history, physical examination, blood and
urine tests, and imaging studies.
- Cells for treatment will be collected during tumor biopsy or surgery.
- Prior to the start of cell therapy, participants will have imaging procedures, heart
and lung function tests, and blood and urine tests, as well as leukapheresis to collect
additional white blood cells.
- For 5 days before the cell infusion, participants will be admitted for inpatient
chemotherapy with cyclophosphamide and fludarabine to suppress the immune system in
preparation for the cell therapy.
- Participants will receive the modified white blood cells as an infusion 1 to 4 days
after the last dose of chemotherapy. The day after the infusion, participants will
receive filgrastim to stimulate blood cell growth.
- Participants will remain as inpatients for at least 5 to 10 days to recover from the
treatment, and will be followed regularly after the treatment to study side effects and
general effectiveness.
- Participants who initially respond to treatment but have a relapse may have one
additional treatment using the same procedure.

Background:
- Interleukin-12 (IL-12) is an important immunostimulatory cytokine. We have constructed
a retroviral vector that contains an inducible single chain IL-12 driven by an nuclear
factor of activated T-cells (NFAT) responsive promoter which can be used to mediate
transfer of this gene into anti-tumor lymphocytes. This construct enables the secretion
of IL-12 following stimulation of the T cell receptor.
- Transduction of the IL-12 gene into mouse anti-tumor lymphocytes results in a profound
increase in the ability of these lymphocytes to mediate tumor regression following
administration to tumor bearing mice. These cells have a profound advantage in inducing
anti-tumor responses because very few cells are needed and there is no requirement for
the concomitant administration of interleukin-2 (IL-2) as is the case for conventional
cell transfer immunotherapies.
- Based on these murine studies we have now constructed a similar retrovirus that
contains an inducible human single chain IL-12 driven by an NFAT responsive promoter.
This retrovirus can be used to transduce tumor infiltrating lymphocytes (TIL) suitable
for the therapy of patients with metastatic melanoma.
Objectives:
Primary objectives:
- To evaluate the safety of the administration of IL-12 engineered TIL in patients
receiving a non-myeloablative conditioning regimen.
- Determine if the administration of IL-12 engineered TIL to patients following a
non-myeloablative but lymphoid depleting preparative regimen will result in clinical
tumor regression in patients with metastatic cancer.
Secondary objective:
-Determine the in vivo survival of IL-12 gene-engineered cells.
Eligibility:
Patients who are 18 years of age or older must have:
- metastatic melanoma;
- Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1;
Design:
- TIL will be resected from metastatic deposits and grown in IL-2 using standard
techniques.
- Prior to approval of amendment A, after about 2 weeks TIL will undergo cluster of
differentiation 8 (CD8) enrichment on a Miltenyi column and then undergo a rapid
expansion by exposure to Muromoanb-CD3) OKT-3 an IL-2 in the presence irradiated feeder
cells. Four to five days later, transduction is initiated by addition of retroviral
vector supernatant containing the IL-12 gene.
With approval of amendment A, TIL will not undergo CD8 enrichment. Starting with cohort 5,
after initial growth, TIL undergo a rapid expansion by exposure to OKT-3 and IL-2 in the
presence irradiated feeder cells. Four to five days later, transduction is initiated by
addition of retroviral vector supernatant containing the IL-12 gene.
- Patients will receive a nonmyeloablative but lymphocyte depleting preparative regimen
consisting of cyclophosphamide and fludarabine followed by intravenous infusion of
IL-12 gene-transduced TIL. Cohorts of 3 patients each will receive increasing cell
doses.
- Patients will undergo complete evaluation of tumor with physical examination, computed
tomography (CT) of the chest, abdomen and pelvis and clinical laboratory evaluation
four to six weeks after treatment. If the patient has stable disease (SD) or tumor
shrinkage, repeat complete evaluations will be performed every 1-3 months. After the
first year, patients continuing to respond will continue to be followed with this
evaluation every 3-4 months until off study criteria are met.
- The study will be conducted using a Phase I/II optimal design. The protocol will
proceed in a phase 1 dose escalation design.
- Prior to approval of amendment A, the protocol enrolled 1 patient in each of the first
3 dose cohorts. Cohort 4 proceeded in a phase 1 dose escalation design, with of n=3.
Should a single patient experience a dose limiting toxicity due to the cell transfer at
a particular dose level, additional patients would be treated at that dose to confirm
that no greater than 1/6 patients have a dose-limiting toxicity (DLT) prior to
proceeding to the next higher level. If a level with 2 or more DLTs in 3-6 patients has
been identified, three additional patients will be accrued at the next- lowest dose,
for a total of 6, in order to further characterize the safety of the maximum tolerated
dose.
- With approval of amendment A, no additional patients will be enrolled in cohort 4, and
the protocol will enroll 1 patient in cohort 5 with a dose of 1 X 10^7 bulk young TIL
cells. Cohorts 6-12 will proceeded in a phase 1 dose escalation design, with an n=3.
Should a single patient experience a dose limiting toxicity due to the cell transfer at
a particular dose level, additional patients would be treated at that dose to confirm
that no greater than 1/6 patients have a DLT prior to proceeding to the next higher

additional patients will be accrued at the next-lowest dose, for a total of 6, in order
to further characterize the safety of the maximum tolerated dose prior to starting the
pahse II portion. If a dose limiting toxicity occurs in the cohort 4, that cohort will
be expanded to 6 patients. If 2 DLTs are encountered in this cohort, the study will be
terminated.
- Once the maximum tolerated dose (MTD) has been determined, the study then would proceed
to the phase II portion using a phase II optimal design where initially 21 evaluable
patients will be enrolled. If 0 or 1 of the 21 patients experiences a clinical
response, then no further patients will be enrolled but if 2 or more of the first 21
evaluable patients enrolled have a clinical response, then accrual will continue until
a total of 41 evaluable patients have been enrolled.
- The objective will be to determine if the combination of lymphocyte depleting
chemotherapy, and IL-12 gene engineered lymphocytes is associated with a clinical
response rate that can rule out 5% (p0=0.05) in favor of a modest 20% partial response
(PR) + complete response (CR) rate (p1=0.20).
