In this study, these special immune T-cells will be taken from a sample of the participant's
tumor tissue that will be surgically removed. Certain parts of these cells will be
multiplied, or grown, in the laboratory. They will then be given back to the patient by an
infusion in their veins. These cells are called tumor infiltrating lymphocytes (TIL). The
investigators want to study the benefits and side effects of TIL when they are given with
the following combination of drugs:
- Vemurafenib - a type of drug used to slow the growth of certain types of cancer cells.
This drug will be given for about three weeks while T-cells are being grown in the lab
and then again after T-cell infusion for up to two years.
- Fludarabine and cyclophosphamide - two types of chemotherapy drugs. These drugs will be
used for what is called lymphodepletion. The purpose of lymphodepletion in this study
is to temporarily reduce the number of normal lymphocytes circulating in the patient's
body before they are given the T-cells that were grown in the lab. This is so that
there will be more "space" for the lymphocytes (T-cells) that will be infused in their
- Interleukin-2 (IL-2) - a drug used to help the body's response to treatment on the
immune system. A high dose regimen of IL-2 will be given after they receive the
infusion of the T-cells.
The use of TIL is investigational, meaning it has not been approved by the U.S. Food and
Drug Administration (FDA). Vemurafenib and IL-2 have been approved by the FDA for the
treatment of metastatic melanoma and melanoma that cannot be surgically removed. The
chemotherapy drugs fludarabine and cyclophosphamide, used for lymphodepletion, have been
approved by the FDA, but not for the treatment of metastatic melanoma.
The combination of vemurafenib followed by lymphodepletion with chemotherapy, TIL infusion,
and high dose IL-2 is investigational, and has not been proven to help treat melanoma. This
combination is not FDA approved; however, the FDA is allowing its use in this study.
- Must have unresectable metastatic stage IV melanoma or stage III intransit or
regional nodal disease and in the opinion of the PI or treating Coinvestigator is an
acceptable candidate for adoptive cell transfer (ACT).
- Residual measurable disease after resection of target lesion(s) for TIL growth
- Tumor must have a B-RAF V600E, D or K mutation by pyrosequencing, Cobas assay, or
- Clinical performance status of Eastern Cooperative Oncology Group (ECOG) 0 - 1. ECOG
performance status of 0-1 will be inferred if the patient's level of energy is 50%
- May be treatment-nave or may have been previously treated for metastatic disease.
- Women of childbearing potential (WOCBP) must have a negative serum pregnancy test
within 7 days of starting Vemurafenib.

patients with Gilbert's Syndrome who must have a total bilirubin less than 3.0 mg/dL,
aspartic transaminase (AST) and alanine transaminase (ALT) of less than 3X
institutional upper limit of normal, hemoglobin of 8 gm/dL or more, white blood count
(WBC) of 3000 per mcL and total granulocytes of 1000 per mcL or more, and platelets
of 100,000 per mcL or more.
- Must have a positive screening Epstein-Barr Virus (EBV) antibody titre on screening
- Patients with antibiotic allergies per se are not excluded; although the production
of TIL for adoptive transfer includes antibiotics, extensive washing after harvest
will minimize systemic exposure to antibiotics.
- At screening, patients with 3 untreated CNS metastases may be included provided
none of the untreated lesions are > 1 cm in greatest dimension, and there is no
peri-tumoral edema present on brain imaging (MRI or CT if MRI is contraindicated).
- At screening, patients with 3 treated central nervous system (CNS) metastases
treated with either surgical resection and/or radiation therapy may be included.
Patients may be included if the largest lesion is 1 cm, and there is no evidence of
progressive CNS disease on brain imaging at least 28 days after treatment.
- At screening, may be included if the largest lesion is > 1 cm or > 3 in number, and
there is no evidence of progressive CNS disease on brain imaging at least 90 days
after treatment with surgery and/or radiation therapy.
- At screening, must have no known history of congenital long QT syndrome and must have
a corrected mean QTc interval 450 msec at baseline.
- No evidence of ongoing cardiac dysrhythmia grade 2, NCI Common Terminology Criteria
for Adverse Events (CTCAE) v4.0
- All laboratory and imaging studies must be completed and satisfactory within 30 days
of signing the consent document, with the exceptions of: negative serum pregnancy
test for WOCBP must be negative within 7 days of starting Vemurafenib, human
leukocyte antigen (HLA) typing which will not be repeated if performed previously,
and pulmonary function tests/cardiac stress tests whose results are valid for 6
months if performed previously.
- Patients with active systemic infections requiring intravenous antibiotics,
coagulation disorders or other major medical illness of the cardiovascular,
respiratory or immune system, which in the opinion of the principal investigator (PI)
or treating co-investigator is not acceptable risk for ACT, are excluded.
- Patients testing positive for HIV titre, Hepatitis B surface antigen, Hepatitis B
core antibody, Hepatitis C antibody, human T-cell lymphotropic virus type (HTLV) I or
II antibody, or both rapid plasma reagin (RPR) and fluorescent treponemal antibodies
- Patients who are pregnant or nursing
- Patients needing chronic, immunosuppressive systemic steroids are excluded
- Patients with autoimmune diseases that require immunosuppressive medications
- Presence of a significant psychiatric disease, which in the opinion of the principal
investigator or his designee, would prevent adequate informed consent or render

- Patients with 3 untreated CNS metastases but with at least one lesion >1 cm or
- Patients with congenital long QT syndrome
- Patients with invasive malignancy other than melanoma at the time of enrollment and
within 2 years prior to the first Vemurafenib administration are excluded, except for
