Summary

This randomized phase II trial studies how well giving pembrolizumab with standard chemotherapy, tumor infiltrating lymphocytes (TIL), and aldesleukin works in treating patients with melanoma that has spread to other areas of the body. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine phosphate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving an infusion of TIL, or white blood cells, may help stimulate the immune system to help kill more cells. Aldesleukin may also stimulate the white blood cells to kill melanoma cells. Giving pembrolizumab together with standard chemotherapy, TIL, and high- or low-dose aldesleukin may help stop the melanoma from spreading.

Eligibility Criteria

Inclusion Criteria

  • TURNSTILE I - SCREENING:
  • Patients must have metastatic melanoma or stage III in-transit, subcutaneous, or regional nodal disease
  • Patients must have a lesion amenable to resection for the generation of TIL on MD Anderson protocol 2004-0069
  • Patients must receive a magnetic resonance imaging (MRI)/computed tomography (CT)/positron emission tomography (PET) of the brain within 6 months of signing informed consent; if new central nervous system (CNS) lesions are present, patient must have definitive treatment (including surgery or radiation); principal investigator (PI) or his designee should make final determination regarding enrollment
  • Clinical performance status of Eastern Cooperative Oncology Group (ECOG) 0 - 1 within 30 days of signing informed consent
  • Patients previously treated with immunotherapy, targeted therapy, or no therapy (treatment naive) will be eligible
  • Patients receiving cytotoxic agents will be evaluated by the PI or his designee for eligibility suitability
  • Patients with a negative pregnancy test (urine or serum) must be documented within 14 days of screening for women of childbearing potential (WOCBP); a WOCBP has not undergone a hysterectomy or who has not been naturally postmenopausal for at least 12 consecutive months (i.e. who has not had menses at any time in the preceding 12 consecutive months)
  • TURNSTILE II - TREATMENT:
  • Patients must sign the treatment consent document before Turnstile II screening procedures; before the treatment starts and at each visit, the patient will be asked to complete two quality of life questionnaires; It should take about 15 minutes to complete the questionnaires (Functional Assessment of Cancer Therapy General [FACT-G], FACT-Melanoma); patients must fulfill all of the following criteria to be eligible for Turnstile II of the study
  • Patients must have adequate TIL that were previously harvested and then cryopreserved on MD Anderson Cancer Center (MDACC) protocol 2004-0069
  • Patients who have had prior therapy (BRAF inhibitors, ipilimumab, anti PD-1 antibody or anti PD-L1 antibody) or treatment naive patients are eligible as long as toxicity from therapy is grade = 1 cm and must be amenable to undergoing serial biopsies through the course of therapy; this lesion must not be documented as one of the target lesions
  • Patients may have central nervous system (CNS) metastases which have been treated and are radiographically stable for at least 4 weeks
  • Patients of both genders must practice birth control for four months after receiving the preparative regimen (lymphodepletion) and continue to practice birth control throughout the study; patients must have a documented negative pregnancy test (urine or serum) for women who have menstruated in the past 12 months and without sterilization surgery
  • Unless surgically sterile by bilateral tubal ligation or vasectomy of partner(s), or if the patient is post-menopausal, the patient agrees to continue to use a barrier method of contraception throughout the study such as: condom, diaphragm, hormonal, intrauterine device (IUD), or sponge plus spermicide; abstinence is an acceptable form of birth control
  • Pregnancy testing will be performed within 14 days of screening for women of childbearing potential (WOCBP); a WOCBP has not undergone a hysterectomy or who has not been naturally postmenopausal for at least 12 consecutive months (i.e. who has not had menses at any time in the preceding 12 consecutive months)
  • Clinical performance status of ECOG 0-1 within 30 days of signing informed consent
  • A stress cardiac test (stress thallium, stress multi-gated acquisition scan [MUGA], dobutamine echocardiogram or other stress test that will rule out cardiac ischemia) within 1 month of lymphodepletion
  • 12-lead electrocardiogram (EKG) showing no active ischemia and corrected QT (QTc) interval less than 480 msec
  • Pulmonary function tests (forced expiratory volume in 1 second [FEV1] > 65% or forced vital capac
