Overview
Brief Summary
Single center, single arm phase Ib trial to test the feasibility and safety of Tumor- Infiltrating Lymphocyte-Adoptive Cell Therapy (TIL-ACT) combined with low-dose irradiation in patients with advanced or metastatic solid tumors. The trial is based on lymphodepleting chemotherapy followed by low dose irradiation (LDI), and then ACT utilizing ex vivo expanded TILs in combination with high dose IL-2 (optional, depending on patient's tolerance). LDI will be administered once to metastatic lesions using tomotherapy.
Detailed Description
The objective of the trial is to define the feasibility and safety of TIL-ACT in combination with low-dose irradiation (LDI) in patients with advanced or metastatic solid tumors. Study treatment will begin with intravenous (IV) non-myeloablative (NMA) lymphodepleting chemotherapy composed by fludarabine and cyclophosphamide. Both treatments will be started on the same day. Fludarabine will be administered for five days, and cyclophosphamide for two days. Low-dose irradiation (LDI) will be then administered once, to up to 20 measurable tumor lesions using tomotherapy. TIL infusion will be performed intravenously followed by high dose IL-2 administration every eight hours, for a maximum of eight doses. Supportive care will be given as needed during the whole treatment period. Patients achieving a stable disease, partial response or complete response after TIL-ACT treatment will then enter a follow-up period for 5 years.

Eligibility Criteria
Inclusion Criteria
- •Patients with locally advanced (not radically treatable) or metastatic solid tumors with the below cancer types, who progressed after at least one standard therapy for advanced disease, or for whom such therapy was proven to be intolerable, or is considered inappropriate. Prior immunotherapy is allowed.
- •Breast cancer: irrespective of hormone receptor, Human epidermal growth factor receptor 2 (HER2) status or molecular subtype.
- •Non-small cell lung cancer (NSCLC): irrespective of histological or molecular subtypes.
- •Ovarian cancer: patients with high-grade serous ovarian cancer (HGSOC).
- •Colon cancer: irrespective of molecular subtype.
- •Other solid tumor: Patients with any other histology (any molecular subtype) with the exception of primary brain tumors, as well as cutaneous, mucosal, and ocular/uveal melanoma.
- •Patients who have previously undergone tumor resection or biopsy and for whom pre-REP TILs are already available and adequate for further REP expansion. The following conditions have to be met:
- •a. The Manufacturing facility / sponsor representative confirms that adequate pre-REP material (in quantity and quality) is available to move to REP.
- •At least one lesion accessible to biopsy for translational research (TR) at baseline and D30, without putting the patient at unusual risk. Every effort should be made to obtain a fresh tumor biopsy upon enrolment, if previous collection of tissue is judged insufficient for study translational endpoints. The following exceptions are accepted for the baseline biopsy:
- •a. Tumor material was properly collected for all protocol translational endpoints during harvesting surgery or biopsy for the TIL production (pre-REP) and no intercurrent anticancer therapy has been administered since that surgery or last biopsy. If patient has been treated with any antitumor therapy that may have altered the tumor microenvironment at the estimation of the PI, a repeat biopsy should be performed.
Exclusion Criteria
- •Patients with an active second malignancy, except for
- •non-melanoma skin cancer that has been apparently cured or successfully resected
- •carcinoma in situ as long as they have been adequately treated
- •Any malignancy that can be adequately managed expectantly without compromising prognosis, and after PI agreement..
- •Patients who have a history of malignancy are not considered to have an active malignancy if they have completed therapy since at least 2 years and are considered by their treating investigator to be at ≤ 30% risk for relapse.
- •Patients with known peritoneal metastases who have a recent history of intermittent bowel obstruction (even partial), unless such obstruction has been resolved. Agreement with the Trial Chair is mandatory.
- •Patients with leptomeningeal carcinomatosis
- •History of idiopathic pulmonary fibrosis or evidence of active pneumonitis (any origin)
- •History of recent myocardial infarction or unstable angina, either within six months of enrolment
- •Documented Child-Pugh score of B or C for hepatocellular carcinoma patients with known underlying liver dysfunction

Outcomes
Primary Outcomes
Feasibility of TIL-ACT in combination with LDI - successful Rapid Expansion Protocol (REP): Number of patients for whom TIL cultures
Time Frame: Evaluated for each patient at day 0. After day 0 of the last patient, the number of patients with successful TIL-ACT infusion will be calculated.
Number of patients for whom TIL cultures after REP achieve the required cell number and release criteria to start TIL-ACT infusion.
Feasibility of TIL-ACT in combination with LDI - successful infusion: Number of patients receiving a complete TIL-ACT infusion
Time Frame: Evaluated for each patient at day 0, up to 60 mins after start of TIL-ACT infusion. At day 0 of the last patient, the number of patients with successful TIL-ACT infusion will be calculated.
Number of patients receiving a complete TIL-ACT infusion (planned NMA chemotherapy, planned LDI and at least partial TIL infusion; no minimum IL-2 required)
Toxicity of TIL-ACT and LDI
Time Frame: Treatment limiting toxicity (TLT) period: from chemotherapy start until Day30
Number of patients with adverse events as assessed by CTCAE version 5.0
