Melanoma Clinical Trial
A Prospective Randomized and Phase 2 Trial for Metastatic Melanoma Using Adoptive Cell Therapy With Tumor Infiltrating Lymphocytes Plus IL-2 Either Alone or Following the Administration of Pembrolizumab
Summary
Background:
Cell therapy is an experimental cancer therapy. It takes young tumor infiltrating lymphocytes (Young TIL) cells from a person s tumors and grows them in a lab. Then they are returned to the person. Researchers think adding the drug pembrolizumab might make the therapy more effective.
Objective:
To test if adding pembrolizumab to cell therapy is safe and effective to shrink melanoma tumors.
Eligibility:
People ages 18-70 years with metastatic melanoma OF THE SKIN
Design:
Participants will be screened with:
Physical exam
CT, MRI, or PET scans
X-rays
Heart and lung function tests if indicated
Blood and urine tests
Before treatment, participants will have:
A piece of tumor taken from a biopsy or during surgery in order to grow TIL cells
Leukapheresis: Blood flows through a needle in one arm and into a machine that removes white blood cells.
The rest of the blood returns through a needle in the other arm.
An IV catheter placed in the chest for getting TIL cells, aldesleukin, and pembrolizumab (if assigned)
Participants will stay in the hospital for treatment. This includes:
Daily chemotherapy for 1 week
For some participants, pembrolizumab infusion 1 day after chemotherapy
TIL cell infusion 2-4 days after chemotherapy, then aldesleukin infusion every 8 hours for up to 12 doses
Filgrastim injections to help restore your blood counts
Recovery for 1-3 weeks
After treatment, participants will:
Take an antibiotic and an antiviral for at least 6 months, as applicable
If assigned, have pembrolizumab treatment every 3 weeks for 3 more doses. They may have another round.
Have 2-day follow-up visits every 1-3 months for 1 year and then every 6 months
Full Description
Background:
- Adoptive cell therapy (ACT) using autologous tumor infiltrating lymphocytes (TIL) can mediate the regression of bulky metastatic melanoma when administered along with highdose aldesleukin (IL-2) following a non-myeloablative lymphodepleting
preparative regimen consisting of cyclophosphamide and fludarabine.
- Pembrolizumab, a monoclonal antibody that binds to PD-1 and blocks the PD-1/PD-L1 axis, facilitates the activity of anti-tumor lymphocytes in the tumor micro environment. Pembrolizumab administration can result in objective tumor responses in patients with
metastatic melanoma and is approved for use by the FDA for the treatment of these patients.
Administered TIL express low levels of PD-1, though PD-1 can be re-expressed on TIL in vivo following TIL administration
In pre-clinical models, the administration of an anti-PD1 antibody enhances the anti-tumor activity of transferred T-cells.
Objectives:
Primary Objectives:
Determine in a prospective randomized trial whether the addition of pembrolizumab to the standard non-myeloablative conditioning regimen, TIL, and high-dose IL-2 can improve complete response rates in patients with metastatic melanoma who have received prior anti PD-1/PD-L1 therapy (Cohort 1)
Determine the complete response rate to the standard non-myeloablative conditioning regimen, TIL, and high-dose IL-2 in combination with pembrolizumab in patients with metastatic melanoma who have not received prior anti-PD-1/PD-L1 therapy (Cohort 2)
Eligibility:
Age greater than or equal to 18 and less than or equal to 70 years
Evaluable metastatic melanoma
Metastatic melanoma lesion suitable for surgical resection for the preparation of TIL
No allergies or hypersensitivity to high-dose aldesleukin administration
No concurrent major medical illnesses or any form of immunodeficiency
Design:
Patients with metastatic melanoma will have lesions resected for TIL
Patients will be assigned one of 2 cohorts: (1)
patients who are refractory to prior anti PD-1/PD-L1
patients who have not received prior anti PD-1/PD-L1
After TIL growth is established:
Patients assigned to Cohort 1 will be randomized to either receive or not receive pembrolizumab in combination with the standard non-myeloablative conditioning regimen, TIL and high dose IL-2
All patients assigned to Cohort 2 will receive the standard nonmyeloablative conditioning regimen, TIL, and high-dose IL-2ACT in combination with pembrolizumab.
For those patients receiving pembrolizumab- Pembrolizumab will be administered immediately prior to TIL administration and continue for an additional three cycles following the cell infusion.
Up to 170 patients may be enrolled over 3-4 years.
Eligibility Criteria
-INCLUSION CRITERIA:
Measurable metastatic melanoma with at least one lesion that is resectable for TIL generation.
Confirmation of diagnosis of metastatic melanoma by the Laboratory of Pathology of NCI.
Patients must have received at least one prior therapy for metastatic melanoma.
Patients with 3 or fewer brain metastases that are less than 1 cm in diameter and asymptomatic are eligible. Lesions that have been treated with stereotactic radiosurgery must be clinically stable for 1 month after treatment for the patient to be eligible. Patients with surgically resected brain metastases are eligible.
Greater than or equal to 16 years of age and less than or equal to 70 years of age.
All participants and/or their parents or legally authorized representatives must sign a written informed consent. Assent will be obtained for all participants under the age of 18 years.
All participants greater than or equal to 18 years of age or older must be willing to sign a durable power of attorney
Clinical performance status of ECOG 0 or 1.
Patients of both genders must be willing to practice birth control from the time of enrollment on this study and for up to four months after treatment.
Serology:
Seronegative for HIV antibody. (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who are HIV seropositive can have decreased immune-competence and thus are less responsive to the experimental treatment and more susceptible to its toxicities.)
Seronegative for hepatitis B antigen, and seronegative for hepatitis C antibody. If hepatitis C antibody test is positive, then patient must be tested for the presence of antigen by RT-PCR and be HCV RNA negative.
Women of child-bearing potential must have a negative pregnancy test because of the potentially dangerous effects of the treatment on the fetus.
Hematology
Absolute neutrophil count greater than 1000/mm3 without the support of filgrastim

More than four weeks must have elapsed since any prior systemic therapy at the time the patient receives the preparative regimen, and patients toxicities must have recovered to a grade 1 or less (except for toxicities such as alopecia or vitiligo). (Note: Patients may
have undergone minor surgical procedures within the past 3 weeks, as long as all toxicities have recovered to grade 1 or less)
Patients must demonstrate progressive disease at the time of treatment. (Note: Patients who have received tyrosine kinase inhibitors (e.g. vemurafinib) may be treated if they present with stable disease at the time of treatment).
Subjects must be co-enrolled in protocol 03-C-0277.
EXCLUSION CRITERIA:
Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the treatment on the fetus or infant.
Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency Disease).
