About
This is a phase 1b study for patients with metastatic (cancer has spread to various parts of the body) melanoma and ovarian cancer. The main purpose is to examine the safety and efficacy of administering pembrolizumab after receiving chemotherapy, tumor-infiltrating lymphocytes (TIL) and low dose interleukin 2 (IL-2).
Patients will first receive either cyclophosphamide, or cyclophosphamide and fludarabine. These are chemotherapy agents that prepare the body to receive TILs.
Patients are then infused with autologous TILs, a type of white blood cell that recognizes tumor cells and enters them, thereby causing tumor cells to break down.
Following TILs infusion, patients will receive low-dose IL-2 therapy. This is a type of protein that is intended to activate and stimulate the growth of cells in the patient's immune system.
If the patient meets the required criteria, they will be given pembrolizumab, a monoclonal antibody (drug made up of cloned immune cells) that is designed to block a protein called programed cell death ligand 1 (PD-L1) which will allow the body's immune system to kill the cancer cells.
Full description
This study will involve treatment with chemotherapy, TILs, IL-2, pembrolizumab, tests and procedures done for safety, and the collection of archival tumor tissue, fresh tumor biopsies, and blood samples for biomarker research.

Inclusion and exclusion criteria
Pre-TIL Inclusion Criteria:
Cohort 1 Pre-TIL inclusion criteria:
Cohort 2 Pre-TIL inclusion criteria:
Platinum resistant ovarian cancer, histologically confirmed
• Platinum resistant as defined by evidence of radiographic progression within 6 months of the last dose of platinum.
Prior systemic anti-CTLA-4 therapy is allowed, provided that the first dose of pembrolizumab is administered more than 6 weeks after the last dose of anti-CTLA-4 treatment.
Eligible for ACT with autologous TIL
Both Cohorts 1 and 2 (pre-TIL):
Subjects may have 3 or fewer asymptomatic brain metastases, ≤ 1 cm in size each. Note: If lesions are symptomatic, >1 cm each in size, or more than 3 in number, these lesions must undergo definitive treatment with surgery and/or radiation at least four weeks days prior to the first dose of lymphodepleting chemotherapy. If in the opinion of the PI or his designee the lesion(s) no longer represents active disease, the subject will be considered eligible.
No history of serious cardiac illness including (but not confined to):
Subjects who have a prolonged history of cigarette smoking or symptoms of respiratory dysfunction should not have abnormal pulmonary function test as evidenced by a FEV1 < 60% predicted within 4 weeks of chemotherapy.
Exclusion Criteria:
Subjects with ongoing prior use of systemic steroid therapy within 4 weeks before the TILs infusion will be excluded. Use of topical, intranasal and inhaled corticosteroids, or systemic corticosteroids at physiologic doses are allowed.
