Men must agree to avoid fathering a child while on treatment and for 6 months following the last dose of treatment. ECOG Performance Status 0-1 or equivalent Karnofsky score at the time of enrollment. Patients need to have received at least 1 prior line of systemic therapy before participation in this protocol and have no therapeutic options with possibility of cure or durable remission. Subjects with squamous cell carcinoma of the head and neck must have received a platinum containing chemotherapy regimen for treatment of primary tumor in locally advanced, or metastatic settings and must have received an anti-PD-1/ PD-L1 as monotherapy or in combination with chemotherapy. Subjects with melanoma must have received an anti-PD-1/ PD-L1 inhibitor as monotherapy or in combination with anti-CTLA-4 inhibitor or anti-PD-1 in combination with anti-LAG-3 determined to have either primary or secondary CPI resistance. Subjects with tumors having known actionable molecular alterations such as BRAF and MEK for which FDA-approved medications are available must have progressed on directed molecular therapy. Exclusion Criteria: Active brain metastases or leptomeningeal metastases. Participants with brain metastases are eligible if these have been treated and there is no MRI evidence of progression for at least 4 weeks after treatment is complete. There must also be no requirement for immunosuppressive doses of systemic corticosteroids (> 10 mg/day prednisone equivalents). Stable doses of anticonvulsants are allowed. Treatment for CNS metastases may include stereotactic radiosurgery (e.g. Gamma Knife, Cyber Knife, or equivalent) or neurosurgical resection. Patients who received whole brain radiation therapy are not eligible. Any condition including medical, emotional, psychiatric, or logistical that, in the opinion of the Investigator, would preclude the patient from adhering to the protocol or would increase the risk associated with study participation or study drug administration or interfere with the interpretation of safety results (e.g., a condition associated with diarrhea or acute diverticulitis). Prior malignancy active within the previous 3 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or localized carcinoma of the prostate, cervix, or breast. Participants with an active, known or suspected autoimmune disease requiring active treatment. Participants with type I diabetes mellitus, hypothyroidism requiring only hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll. Requirement for greater than physiological doses of corticosteroids (> 10 mg daily prednisone equivalent) Requirement for other immunosuppressive medications including but not limited to anti-TNF antibodies, mycophenylate mofetil and methotrexate.

Patients who have had chemotherapy, radiotherapy, biologics, other anti-neoplastic or investigational agents, and/or other antitumor treatment including immunotherapy within 2 weeks (14 days) of Day -5, or those who have not recovered from adverse events related to therapies administered more than 4 weeks (28 days) earlier, are not eligible to enroll. All adverse events related to prior therapy must have improved to grade 1 or better before study participation. Focal radiotherapy (examples include SRS, Palliative or MRI-Linac) completed at least 2 weeks (14 days) prior to the first dose study treatment are permitted to enroll. Patients with evidence of ischemia on exercise tolerance test, stress thallium study, or baseline EKG are excluded. DLCO, FEV1 or FEV1/FVC less than 65% of predicted due to clinically significant underlying pulmonary disease.

5. Study Description

Brief Summary
The subject of this study is the adoptive transfer of selected autologous tumor infiltrating lymphocytes (TIL) after in vitro expansion for the treatment of solid tumor malignancies. The TIL selection process is based on evidence showing that CD8+ TIL which co-express both CD39 and CD103 harbor the bulk of tumor-reactivity and that the remaining CD8 TIL is mainly composed of non-tumor reactive bystander cells. All of the expanded TIL that are produced (1-40 billion are expected) will be delivered in the form of a cell suspension to the participants by intravenous infusion. It is proposed that these selected TIL will produce a more potent and efficacious treatment of late-stage cancer.
Detailed Description
Our research identified a subpopulation of CD8 tumor infiltrating lymphocytes (TIL) highly enriched for tumor reactivity that can be identified and isolated based on the co-expression of CD39 and CD103. The investigators refer to this tumor-reactive cell population as DP CD8 TIL. The DP CD8 TIL can constitute as few as 2% and up to 70-80% of the CD8 TIL directly isolated from tumors, suggesting that in any given patient a substantial percentage of their CD8 TIL can be bystanders lacking tumor specificity. The CD8 DP TIL were highly enriched for cells that recognize autologous tumor as evidenced by interferon gamma production, 4-1BB upregulation and autologous tumor cell killing. The investigators also found that T cell receptors within the CD8 DP TIL population share very little overlap with the other sub-populations of CD8 TIL, suggesting that they have a distinct antigen recognition pattern. The DP CD8 TIL express high levels of PD-1 especially when encountering tumor Ag(s) in situ. Pre-clinical experiments have shown that the potency of DP CD8 TIL can be enhanced by decreasing PD-1 checkpoint expression by incubating them with siRNA that targets PD-1. The investigators hypothesize that transient knockdown of PD-1 expression will enable DP CD8 TIL to initiate a more effective and persistent anti-tumor response without increasing toxicity. The investigators refer to DP CD8 TIL after PD-1 knockdown as DP CD8 TIL KD. Although preclinical experiments have shown the value of siRNA modulation of PD-1 in DP T cells, this strategy has not been studied in humans. The main goals of this phase I first-in-human study are to define toxicity and understand the biology and anti-tumor activity of DP CD8 TIL alone and with siRNA PD-1 modulation. Thus, the trial is designed as a randomized comparison of DP CD8 TIL and DP CD8 TIL KD with comprehensive immune monitoring as detailed below. Lymphodepleting chemotherapy just before adoptive transfer facilitates proliferation and persistence of adoptively transferred T cells as has been demonstrated in other adoptive cellular therapy trials over the last 30 years. Similarly, interleukin-2 (IL-2) administered after adoptive transfer enhances T-cell proliferation, persistence, and cytotoxicity. The investigators have also performed pre-clinical experiments confirming the need for IL-2 after DP CD8 TIL adoptive transfer to achieve maximum antitumor effect in a human xenograft model. Cyclophosphamide and fludarabine will be given prior to adoptive transfer of the DP CD8 TIL and high dose IL-2 (600,000 IU/kg IV with a maximum of 6 doses over 6 days) will be administered starting within 24 hours of the adoptive transfer followed by subcutaneous IL-2 in dose-escalation cohorts of IL-2, 5 MIU/m2 TIW starting on day +8 for 1 weeks, 2 weeks or 3 weeks if tolerated.
