A Pilot Study Using Short-Term Cultured Anti-Tumor Autologous Lymphocytes
Study Details
Study Description
Brief 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.

Detailed 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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Cohort 1 Subjects will receive a non-myeloablative lymphocyte depleting preparative regimen of cyclophosphamide (60 mg/kg/day IV) on days -7 and -6 and fludarabine (25 mg/m2/day) on days -5 through -1. Prophylactic antibiotics will be administered as medically indicated until recovery of ANC to > 500 and recovery of ALC to > 400 On day 0 subjects will receive the infusion of autologous TIL and one hour later (but can be delayed up to 24 hours) will begin low-dose aldesleukin (IL-2) (72,000 IU/kg IV every 12 hours for up to 10 doses). |
Drug: Tumor Infiltrating Lymphocytes
The regimen consists of treatment with cyclophosphamide and fludarabine,followed by infusion of up to 3x1011 lymphocytes (minimum of 1x109) expanded in vitro from subjects own resected tumor followed by the administration of aldesleukin (IL-2).

Within 1 week post discharge subjects will be treated with Nivolumab 1 mg/kg and Ipilimumab 3 mg/kg every 3 weeks for 4 doses. Following this, patients will receive Nivolumab 480 mg every 4 weeks. Adjuvant Nivolumab will continue until evidence of disease progression or inability to tolerate treatment. |

Outcome Measures
Primary Outcome Measures
- Adverse Events [up to 12 months]
To determine the safety of administering a regimen of TIL/IL-2, incidence of drug-related adverse events (AEs) will be summarized across adverse event type in terms of frequency by event type.
- Serious Adverse Events [up to 12 months]
To determine the safety of administering a regimen of TIL/IL-2, serious adverse events (SAEs) will be summarized across event type in terms of frequency by event type. SAE's will include events leading to discontinuation, deaths and clinical laboratory test abnormalities
Secondary Outcome Measures
- Objective response rate to TIL [up to 12 months]
Objective response rate (ORR) of the TIL/IL-2 regimen based on investigator review of radiographic images using RECIST 1.1 criteria
Other Outcome Measures
