Registration Number: NCT01807182

Lead Sponsor: Fred Hutchinson Cancer Center

Brief Summary: This phase II trial studies how well tumor-infiltrating lymphocytes (TIL) after combination chemotherapy works in treating patients with melanoma that has spread to other places in the body. Biological therapies, such as TIL, may stimulate the immune system in different ways and stop tumor cells from growing. 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 TIL after combination chemotherapy may kill more tumor cells.

Detailed Description: OUTLINE:

Patients receive cyclophosphamide intravenously (IV) on days -7 to -6 and fludarabine phosphate IV on days -5 to -1. Patients undergo TIL infusion over 30-60 minutes on day 0 and receive aldesleukin IV every 8 hours on days 1-5 for up to a maximum of 14 doses.

After completion of study treatment, patients are followed up at 6, 12, and 24 weeks.

- Congestive heart failure
- Clinically significant hypotension
- Cardiac ischemia, or symptoms of coronary artery disease

Clinically significant autoimmune disorders or conditions of immunosuppression; patients with AIDS or HIV-1 associated complex or known to HIV antibody seropositive or known to be recently PCR+ for hepatitis B or C virus are not eligible for this study; virology testing will be done within 6 months of T cell infusion; the severely depressed or altered immune system found in these patients and the possibility of premature death would compromise study objectives

Primary Outcome Measures

Name	Time	Method
Number of Participants in Each Clinical Response Category	Up to 24 weeks post infusion	Assessed using Response Evaluation Criteria in Solid Tumors 1.1 definitions for complete response, partial response, stable disease, and progressive disease. Clinical response will be determined at 6 weeks, 12 weeks and 24 weeks based on RECIST version 1.137 definitions for Complete Response (CR), Partial Response (PR), Stable Disease (SD) and Progressive Disease (PD). Response reported is best response per participant. A complete response will be defined as total regression of all tumors, a PR as 30% or greater decrease in the sum of the longest diameter of target lesions compared to baseline and PD as 20% increase in the sum of the longest diameter of target lesions compared to the smallest prior diameter (RECIST v1.1 criteria).

Secondary Outcome Measures

Name	Time	Method
Count of Participants Who Experienced Adverse Events, Graded According to National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0	Adverse events will be collected through 4 weeks after T cell infusion. Beginning 4 weeks after the T cell infusion, only study-related toxicities will be collected for up to 1 year following T cell infusion.
Number of Participants Who Experienced in Vivo Persistence of Adoptively Transferred T Cells Following TIL Infusion	Up to 24 months	Whole exome and RNA sequencing of tumor cells and normal tissue was performed to identify non synonymous missense mutations, which was then used to generate peptide pools to identify neoantigen-reactive T cells. T-Cell Receptor (TCR) sequencing of T cell clonotypes in blood at time of treatment, 10 months and 24 months was performed and used to assess the persistence of a tumor antigen specific clonotype infused in the TIL product.
A Count of Participants With Biomarker Expression Above Threshold	Up to 24 weeks	Several biomarkers, CXCL13+ CD4 cells, CXCL13+ CD8+ cells, and regulatory cells were evaluated to assess correlation with clinical responses to TIL therapy.
