Brief Summary:

Single center, single arm pilot trial to test the feasibility, safety and efficacy of NeoTIL-ACT combined with low-dose irradiation (LDI) in patients with advanced, recurrent or metastatic solid tumors.

The trial is based on lymphodepleting chemotherapy followed by LDI, and then ACT utilizing ex vivo expanded TIL, enriched for tumor antigen specificity (NeoTIL), in combination with high dose Interleukin-2 (IL-2) (optional, depending on patient's tolerance).

LDI will be administered once to metastatic lesions using tomotherapy.

Condition or disease Intervention/treatment Phase
Solid Tumor, Adult Other: NeoTIL Drug: Cyclophosphamide Drug: Fludarabine Drug: Interleukin-2 Other: Radiotherapy Phase 1

Detailed Description:

The objective of the trial is to define the feasibility, safety, and efficacy of NeoTIL-ACT in combination with LDI in patients with advanced, recurrent or metastatic solid tumors, as categorized in two molecularly defined cohorts.

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 from for five days, and cyclophosphamide ffor two days. Low-dose irradiation (LDI) will be administered once, to tumor lesions using tomotherapy.

Patients will receive NeoTIL infusion 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 NeoTIL-ACT treatment will then enter a clinical follow-up period for 5 years.
