简要总结
This phase II trial tests how well lifileucel, with reduce dose fludarabine and cyclophosphamide for lymphodepletion and interleukin-2, work for treating patients with melanoma that cannot be removed by surgery (unresectable) or that has spread from where it first started (primary site) to other places in the body (metastatic).Lifileucel is made up of specialized immune cells called lymphocytes or T cells that are taken from a patient's tumor, grown in a manufacturing facility and infused back into the preconditioned patient to attack the tumor. Giving Lifileucel with a reduced dose of fludarabine and cyclophosphamide for lymphodepletion and interleukin -2 is being studied in patients with unresectable or metastatic melanoma.
详细描述
PRIMARY OBJECTIVE:
I. The percentage of total TIL clones as measured by the T-cell receptor (TCR) population shared between the tumor infiltrating lymphocyte (TIL) product and peripheral blood mononuclear cells (PBMC).
SECONDARY OBJECTIVES:
I. To evaluate the efficacy parameters of lifileucel (LN-144) in combination with a reduced dose lymphodepletion in patients with unresectable or metastatic melanoma by assessing objective response rate (ORR), progression-free survival (PFS), and overall survival (OS).
II. To characterize the safety profile of lifileucel (LN-144) in combination with a reduced dose lymphodepletion regimen in patients with unresectable or metastatic melanoma.

研究组 & 干预措施
Treatment (Lifileucel)
Lifileucel (LN-144) is an autologous Tumor Infiltrating Lymphocytes (TIL) cell therapy. A tumor sample is resected from each patient for lifileucel manufacturing. Patients then receive the lifileucel regimen which consists of a reduced dose non-myeloablative lymphodepletion, lifileucel infusion followed by interleukin-2.
干预措施: Interleukin-2 (Biological)
