CISH Inactivated TILs in the Treatment of NSCLC

Inclusion Criteria (1st Screening prior to Tumor Resection - See below for evaluation of continuing eligibility prior to start of investigational treatment):

• Confirmed histologic diagnosis of either PD-L1 negative or positive metastatic non-small cell lung cancer (NSCLC)
• Candidate to receive 1st line treatment with anti-PD-1/anti-PD-L1 immunotherapy in combination with chemotherapy or be within 6 months (Phase 1) or 3 months (Phase 2) of initiation of this type of systemic treatment (regardless of where such treatment was started) when the tumor resection is performed. Patients who have received adjuvant or neoadjuvant anti-PD-1/anti-PD-L1 immunotherapy and/or chemotherapy can be screened for the trial if they experienced a relapse more than 6 months from the end of their last systemic treatment. The tumor resection for investigational product manufacturing should be undertaken before the initiation of this 1st line therapy; however, patients who have already started their 1st line treatment should have these procedures performed and completed as soon as deemed clinically appropriate, but no later than 6 months (Phase 1) or 3 months (Phase 2) from the start of 1st line treatment. After documented radiographic disease progression on or following this 1st line of treatment, patients will receive investigational product as 2nd line therapy.
• Measurable disease per RECIST v1.1 with at least one lesion identified as resectable for cell therapy manufacturing (minimum volume of tumor tissue required is 1 cm^2 as single mass or fragments) and at least one other lesion meeting the RECIST criteria for measurable disease to serve as an indicator of disease response. The location of the tumor resection and method used to obtain tumor (i.e., laparoscopy, endoscopic ultrasound, etc.) will be determined based on an individual patient's disease. Note: previously irradiated lesions with radiographic progression are not eligible for tumor resection.
• Patients who have asymptomatic and or treated brain metastases are eligible, but must be discussed with and approved by the Coordinating Investigator. Lesions that have been treated with stereotactic radiosurgery must be clinically stable for 1 month after treatment for the patient to be eligible. Patients with surgically resected brain metastases are eligible. Patients with brain metastases must not be receiving systemic steroids (oral progestin/estrogen combinations used for contraception are an exception). Brain metastases are assessed using the RANO-BM criteria.
• Clinical performance status of Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 and an estimated life expectancy of ≥ 6 months.
• Age ≥ 18 years and ≤ 70 years.
• Hematology within 14 days of study enrollment:
• Absolute neutrophil count > 1000/mm^3 without the support of filgrastim
• White Blood Cells (WBC) ≥ 3000/mm^3
• Platelet count ≥ 75,000/mm^3
• Hemoglobin > 8.0 g/dL. Subjects may be transfused to reach this cutoff.
• Adequate organ function within 14 days of study enrollment defined as:
• Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 5.0 x upper limit of normal (ULN)
• Serum creatinine ≤ 1.6 mg/dL or creatinine clearance by Cockroft-Gault ≥ 50 mL/min.
• Total bilirubin ≤ to 2.0 mg/dL, except in patients with Gilbert's Syndrome, who must have a total bilirubin ≤ 3.0 mg/dL.
• Serology testing within 3 months of study enrollment (tumor resection):
• Seronegative for HIV antibody. (The investigational treatment being evaluated in this protocol depends on an intact immune system. Patients who are HIV seropositive can have decreased immunocompetence and thus may be less responsive to the study treatment and more susceptible to its toxicities.)
• Seronegative for hepatitis B antigen, and seronegative for hepatitis C antibody. If hepatitis C antibody test is positive, then patient must be tested for the presence of antigen by RT-PCR and be HCV RNA negative.
• Sexually active females of childbearing potential and males with female partners of childbearing potential must agree to use effective contraception for the duration of study treatment starting with Screening and for 12 months (females) and 4 months (males) after the last dose of cyclophosphamide; if receiving pembrolizumab, for 4 months (females and males) after the last dose of pembrolizumab. Examples of effective contraception include oral progestin/estrogen combinations (an exception to the strict prohibition of systemic steroid use), an IUD or implant plus a condom. Women of non-childbearing potential are defined as those who have no uterus, ligation of the fallopian tubes, or permanent cessation of ovarian function due to ovarian failure or surgical removal of the ovaries. A woman also is presumed to be infertile due to natural causes if she has been amenorrheic for > 12 months and/or has a follicle-stimulating hormone (FSH) > 40 IU/L.
• Agrees to remain near the treatment site (within approximately a 1-hour drive) after the investigational product infusion through the Day 28/Week 4 follow-up visit.
• Voluntary written consent prior to the performance of any research-related procedures.

Exclusion Criteria (1st Screening prior to Tumor Resection - See below for evaluation of continuing eligibility prior to start of investigational treatment):

• Pregnant or breastfeeding because of the potentially dangerous effects of the treatment on the fetus or infant. Women of childbearing potential must have a negative pregnancy test (serum or urine) within 7 days of enrollment.

• History of Grade ≥ 2 pneumonitis or active interstitial lung disease/pneumonitis requiring treatment with systemic steroids.
• Documented forced expiratory volume in 1 second (FEV1) ≤ 50% or FEV1/forced vital capacity (FVC) ≤ 0.7 (6-minute walk test if unable to perform or unreliable spirometry).
• Clinically significant patient history that, in the judgment of the enrolling investigator, would compromise the patient's ability to tolerate high-dose aldesleukin.
• Receiving any investigational agents within 21 days prior to tumor collection.
• Medical status or social situation that may make study participation not in the best interest of the patient in the opinion of the enrolling investigator.
