Brief summary: Prospective, open label, non-randomized, phase I/IIb study of F16IL2 in combination with Nivolumab.

Detailed description: The study will take place in two phases. In Phase I, the MTD and RD will be defined following a traditional 3+3 design and patients will be treated in cohorts of 3 to 6 patients with a fixed dose of Nivolumab (3 mg/kg) and escalating doses of F16IL2.

Following successful completion of the dose-finding, the study will proceed to Phase IIb and 17 patients will be treated with Nivolumab (3 mg/kg) and F16IL2 at the RD determined in Phase I.

Eligibility criteria: Inclusion Criteria:

1. Patients aged 18-75 years.
2. Subjects with histologically or cytologically-documented locally advanced NSCLC who present with stage IVA or IVB according to the 8th TNM classification. Pathological characterization must be sufficient to define patients as having either squamous or non-squamous histology.
3. Previous treatment/s for NSCLC with platinum-based 1st line therapy regimen with or without maintainance therapy and documented disease progression. First line platinum-based therapy has to consist of at least 4 cycles.
4. Patients with a known sensitizing mutation in the EGFR gene must have experienced disease progression (during or after treatment) or intolerance to treatment with afatinib, erlotinib, gefitinib, or another EGFR-TKI approved for the treatment of EGFR-mutant NSCLC. Patients with a known ALK fusion oncogene must have experienced disease progression (during or after treatment) or intolerance to treatment with crizotinib or another ALK-TKI approved for the treatment of NSCLC in patients having an ALK fusion oncogene.
5. Evaluable tumor tissue available (either FFPE tissue block or unstained tumor tissue section); fresh or archival.
6. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) 0 or 1.
7. Patients must have at least one unidimensionally measurable lesion by computed tomography or MRIas defined by RECIST criteria 1.1.
8. Prior radiation therapy is allowed, if the irradiated area is not the only source of measurable or assessable disease and if the radiation therapy is not within 4 weeks of the administration of study treatment.
9. All acute toxic effects (excluding alopecia and fatigue) of any prior therapy (including surgery, radiation therapy, chemotherapy) must have resolved to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) (v4.03) Grade ≤ 1.
10. All baseline laboratory requirements will be assessed and should be obtained within 21 days of treatment start. Screening laboratory values must meet the following criteria:

    * Absolute neutrophil count (ANC) ≥ 1.0 x 109/L, platelets ≥ 100 x 109/L, haemoglobin (Hb) ≥ 9.0 g/dl.
    * Alkaline phosphatase (ALP), alanine aminotransferase (ALT) and or aspartate aminotransferase (AST) ≤ 3 x upper limit of reference range (ULN), and total bilirubin ≤ 2.0 mg/L unless liver involvement by the tumor, in which case the transaminase levels could be ≤ 5 x ULN.
    * Creatinine ≤ 1.5 ULN or creatinine clearance ≥ 30 mL/min.
11. Estimated life expectancy of at least 12 weeks.
12. Negative serum pregnancy test for females of childbearing potential\*.
13. Documented negative test for HIV, HBV and HCV. For HBV serology: the determination of HBsAg, anti-HBsAg-Ab and anti-HBcAg-Ab is required. In patients with serology documenting previous exposure to HBV (i.e., anti-HBsAb with no history of vaccination and/or anti-HBcAb), negative serum HBV-DNA is required. For HCV: HCV RNA or HCV antibody test. Subjects with a positive tst for HCV antibody but no detection of HCV RNA indicating no current infection are eligible.
14. Negative TB test (e.g. Mantoux or Quantiferon assay)
15. Written informed consent.

    * Subjects or legal rappresentative must have signed and dated an IRB/IEC approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol related procedures that are not part of normal subject care.
    * Subjects must be willing and able to comply with scheduled visits, treatment schedule, laboratory tests and other requirements of the study.

      * Women of childbearing potential (WOCBP) must be using, from the screening to six months following the last study drug administration, highly effective contraception methods, as defined by the "Recommendations for contraception and pregnancy testing in clinical trials" issued by the Head of Medicine Agencies' Clinical Trial Facilitation Group (www.hma.eu/ctfg.html) and which include, for instance, progesteron-only or combined (estrogen- and progesteron-containing) hormonal contraception associated with inhibition of ovulation, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal occlusion or vasectomised partner. Pregnancy test will be repeated at the end of treatment visit.

Women of childbearing potential are defined as females who have experienced menarche, are not postmenopausal (12 months with no menses without an alternative medical cause) and are not permanently sterilised (e.g., tubal occlusion, hysterectomy, bilateral oophorectomy or bilateral salpingectomy).

Exclusion Criteria:

a. Cancer-specific exclusions

1. Any tumor therapy (chemotherapy, biologics for cancer, or an investigational therapy) within 4 weeks of the administration of study treatment.
2. Uncontrolled tumor-related pain; patients requiring pain medication must be on a stable regimen at study entry. Symptomatic lesions amenable to palliative radiotherapy (e.g., bone metastases or metastases causing nerve impingement) should be treated prior to enrollment.
3. Active symptomatic central nervous system metastases. Subjects are eligible if CNS metastases have been treated and subjects have neurologically returned to baseline (except for residual signs or symptoms related to the CNS treatment) for at least 4 weeks prior to the first administration of study treatment.
4. Subjects must have been either off corticosteroids, or on a stable or decreasing dose ≤ 10 mg daily prednisone (or equivalent) for at least 2 weeks prior to enrollment.
5. Carcinomatous meningitis

   b. General Medical Exclusions
6. Previous or concurrent cancer that is distinct in primary site or histology from the cancer being evaluated in this study or any cancer curatively treated \< 5 years prior to study entry, except cervical carcinoma in situ, non-melanoma skin cancer, superficial bladder tumors.
