Eligibility
Inclusion criteria
* Locally advanced, relapsed or metastatic non-small cell lung cancer (NSCLC) - stage IIIB/IV according to 7th International Association for the Study of Lung Cancer (IASLC) classification * Histologically confirmed diagnosis of non-small cell lung cancer (NSCLC) with rare histological subtype, according to World Health Organization (WHO) 2015 classification. Histologic subtype variants to be enrolled into the study include: colloid adenocarcinoma (or adenocarcinoma with colloid features); fetal adenocarcinoma (or adenocarcinoma with fetal features); large cell carcinoma (LCC); sarcomatoid carcinoma (pleomorphic, spindle cell, and/or giant cell carcinoma, carcinosarcoma, pulmonary blastoma); salivary gland-type tumors (mucoepidermoid carcinoma, adenoid cystic carcinoma, epithelial-myoepithelial carcinoma), other and unclassified carcinomas (lymphoepithelioma-like carcinoma, NUT-nuclear protein in testis-carcinoma) * Availability of tumor sample (material obtained from core-biopsy or surgical specimen) for central pathology revision is mandatory * Availability of a formalin-fixed, paraffin-embedded (FFPE) tumor block or 7-10 unstained tumor slides suitable for PD-L1 expression assessment is mandatory. The assessment of PD-L1 expression will be performed by using both SP-142 and SP-263 antibody assays. The collection of tumor sample should be performed before patients are enrolled into the study * Male and female and ≥ 18 years of age * Life expectancy ≥ 12 weeks * Progressive disease after or during at least one previous standard chemotherapy line * Measurable disease per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1); clear radiological evidence of disease progression after previous treatment has to be documented * Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 to 2 * Patients with treated brain metastases with stable lesions for at least 2 weeks either off steroids or on a stable dose or decreasing dose of steroids (≤ 10 mg prednisone or equivalent daily) will be enrolled. Radiotherapy must have been completed a minimum of 14 days prior to registration, and patients must have recovered from adverse events (AEs) related to radiotherapy to \< grade 1 (except alopecia) * For Females: must be postmenopausal for at least 1 year before the screening visit, or are surgically sterile or not sexually active. Women of childbearing potential (WOCBP) must use 2 effective methods of contraception with a failure rate of less than 1% per year, during the entire study treatment period and for a period of 5 months after the last dose of study drug, or agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. WOCBP must have a negative serum pregnancy test during the screening period * Adequate haematological function defined by white blood cell (WBC) count ≥2,500/mm3 with absolute neutrophil count (ANC) ≥1,500/mm3, platelet count - Adequate hepatic function defined by a total bilirubin ≤ 1.5 x the upper limit of normal (ULN) range (except subjects with Gilbert Syndrome, who can have total bilirubin \< 3.0 mg/dL), serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x ULN (≤ 5 if liver function test elevations are due to liver metastases) * Adequate renal function defined by a serum creatinine ≤ 1.5 x ULN or an estimated creatinine clearance of ≥ 30 mL/minute for patients with creatinine levels above institutional limits (if using the Cockcroft-Gault formula) * Stable medical condition, including the absence of acute exacerbations of chronic illnesses, serious infections, or major surgery within 4 weeks before registration, and otherwise noted in other inclusion/
Exclusion criteria
* Recovered (i.e., ≤ Grade 1 toxicity) from effects of prior anticancer therapy, except alopecia * Ability to comply with protocol requirements * The patient is able to provide written informed consent. Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that the patient may withdraw consent at any time without prejudice to future medical care.

Other
