A Pilot Study Using Short-Term Cultured Anti-Tumor Autologous Lymphocytes

Metastatic Melanoma Clinical Trial

Official title: A Pilot Study Using Short-Term Cultured Anti-Tumor Autologous Lymphocytes Following a Lymphocyte Depleting Regimen in Metastatic Melanoma

Status Terminated

Clinical Trial Summary

To determine the feasibility and safety of administering a regimen of TIL/IL-2, using a cell product manufactured in the Yale Advanced Cell Therapy Laboratories, in subjects with metastatic melanoma who are not responding or have progressed after receiving prior therapy with a PD-1/PD-L1 antagonist used alone or in combination with anti-CTLA-4. Additionally, a second cohort of patients with metastatic melanoma who are not responding or have progressed after receiving prior therapy with a PD-1/PD-L1 antagonist alone or in combination with anti-CTLA-4 will receive anti-PD-1 and anti-CTLA-4 therapy with Nivolumab and Ipilimumab.

Clinical Trial Description

The objectives of this study have been expanded since its original registration to inlcude an additional cohort of patients (now designated Cohort 1 and Cohort 2). Cohort 1 is the original group of patients described in the initial registration of the study.

Cohort 1 Objectives:

• To determine the feasibility and safety of administering a regimen of TIL/IL-2, using a cell product manufactured in the Yale Advanced Cell Therapy Laboratories, in subjects with metastatic melanoma who are not responding or have progressed after receiving prior therapy with a PD-1/PD-L1 antagonist used alone or in combination with anti-CTLA-4.

• To assess for evidence of clinical activity.

• To conduct a preliminary assessment of the TCR clonotypes present in marker positive CD8+ cells (4-1BB, LAG-3, TIM-3, PD-1) versus marker-negative CD8+ T-cells early in the expansion cultures and compare to clonotypes late in the final product and in peripheral blood lymphocytes (PBL) 1 and 2 months post infusion.

Cohort 2 Objectives:

• To determine the feasibility and safety of administering a regimen of TIL/IL-2, using a cell product manufactured in the Yale Advanced Cell Therapy Laboratories, followed by anti-PD-1 and anti-CTLA-4 therapy with Nivolumab and Ipilimumab in subjects with metastatic melanoma who are not responding or have progressed after receiving prior therapy with a PD-1/PD-L1 antagonist alone or in combination with anti-CTLA-4.

• To evaluate the efficacy of TIL/IL-2 therapy in combination with subsequent anti-PD-1 Nivolumab and anti-CTLA-4 Ipilimumab by assessing the objective response rate by immune-related RECIST (irRECIST).

• To conduct a preliminary assessment of the TCR clonotypes present in marker positive CD8+ cells (e.g. 4-1BB, LAG-3, TIM-3, PD-1) versus marker-negative CD8+ T-cells early in the expansion cultures and compare to clonotypes late in the final product and in peripheral blood lymphocytes (PBL) 1 and 2 months post infusion. ;
