About the research

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.

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

Inclusion Criteria:

1. Patients with advanced (not radically treatable), recurrent or metastatic solid tumors of any histology with the exception of primary central nervous system tumors, who have received, and then progressed or been intolerant to at least one standard therapy regimen in the advanced or metastatic setting if such a therapy exists, and have been considered for all other potentially efficacious therapies prior to enrollment. If the participant refuses, or is not eligible for these regimens in the opinion of the investigator, the reason must be documented in the medical record.
2. Patients who have previously undergone tumor resection or biopsy and for whom pre-Rapid Expansion Protocol (REP) NeoTIL cultures are ongoing or completed.

13. Adequate respiratory function with forced expiratory volume in 1 second (FEV1) ≥ 50% predicted, forced vital capacity (FVC) ≥ than 50% predicted and diffusing capacity for carbon monoxide (DLCO) ≥ than 50% predicted corrected. Patients with lung cancer or mesothelioma and values slightly under these limits (but \>30% of predicted) can be enrolled after discussion and approval by the PI. These parameters must be documented within 12 weeks before registration
14. At the time the patient receives the NMA chemotherapy regimen (D-7):

1. ≥14 days or 5 half-lives must have elapsed from any chemotherapeutic cytotoxic drug, whichever is shorter.
2. ≥28 days must have elapsed from bevacizumab, aflibercept and other anti-angiogenic antibodies
3. ≥28 days or 5 half-lives (whichever is shorter) must have elapsed from a non-cytotoxic drug including but not limited to trastuzumab, pertuzumab, and other molecular targeted therapy (such as tyrosine kinase inhibitors, etc…) i) Note: In case of probable tumor flare upon stopping of the non-cytotoxic drug, the investigator may decide to shorten this delay, upon agreement of the Principal Investigator (PI), in a case-by-case approach.
4. ≥21 days must have elapsed from the last antibody therapy that could affect an anti-cancer immune response, including but not limited to anti-Cytotoxic T-lymphocyte-associated protein 4 (CTLA4), anti-Programmed cell death protein 1 (PD-1), anti-Programmed death-ligand 1 (PD-L1), anti-Tumor Necrosis Factor Receptor Superfamily, member 4 (OX-40), or anti-Lymphocyte-activation gene 3 (LAG3) antibody therapy or their combination
