Study of Lifileucel (LN-144), Autologous Tumor Infiltrating Lymphocytes, in the Treatment of Patients With Metastatic Melanoma

Study Purpose

Prospective, interventional multicenter study evaluating adoptive cell therapy (ACT) via infusion of LN-144 (autologous TIL) followed by interleukin 2 (IL-2) after a nonmyeloablative lymphodepletion (NMA LD) preconditioning regimen.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over

Additional Details

Lifileucel is an autologous adoptive cell transfer therapy that utilizes a TIL manufacturing process, as originally developed by the NCI, for the treatment of patients with metastatic melanoma. The adoptive cell transfer therapy used in this study involves patients receiving a lymphocyte depleting preconditioning regimen, prior to infusion of autologous TIL, followed by the administration of a regimen of IL-2.
