Brief summary

This study aims to investigate the role of the gut microbiota and its derived factors, including bacterial-associated antigens that mimic tumor-associated antigens, in predicting response to immune checkpoint inhibitor immunotherapies in patients with various types of cancer. The aim is to explore whether gut microbiota-mediated immunological modulation is specific to the tumor being treated and whether it can be used to enhance antitumor response.

Interventions

BIOLOGICALsample collection

Clinical and radiological assessment will be performed at the enrollment and every 3 +/- 1 months. Clinical information and biological samples will be collected also at 2 years from surgery or start of therapy. We plan collection of a maximum of 13 faecal and blood samples per patient (1 baseline + a maximum of 11 during treatment ± 1 disease progression, ± 10%). In addition, we expect to collect fresh stools and tissue biopsies from at least 3-5 patients per group every year, which will be dedicated to our translational studies.

Inclusion criteria

4.1 INCLUSION CRITERIA: * Histologically or cytologically confirmed disease (see 3.1) * (i) patients with local advanced or metastatic NSCLC candidate to first-line ICB monotherapy or chemo-ICB combination OR (ii) patients with cutaneous melanoma candidate to first-line or adjuvant ICB (iii) patients with primary advanced or first recurrence endometrial or cervical cancer candidate to chemo-ICB combination * Signed Written Informed Consent * Males and Females, ages ≥18 years of age * Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 * Have evaluable disease based on i-RECIST 1.1 * Patients must be willing and able to comply with scheduled visits, treatment schedule, laboratory tests and all protocol procedures. * Be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion, whenever possible. * Known mutation/molecular status as determined by local institutional standard (NSCLC: available comprehensive molecular analysis, melanoma: PD-L1 TPS score, BRAF V600, EC: p53, POLE, MMR status, CC: PD-L1 CPS score. Both wild type and mutation positive are eligible. Regarding gynecologic cancers, EC patients will be eligible for the study regardless of the MMR status (MMRd or MMRp), while only CC patients with a PD-L1 combined positive score (CPS) ≥1 will be eligible. * Patients who have been previously treated in the adjuvant setting for melanoma will be eligible for treatment after a 28-day washout period. * Patients must be medically fit enough to undergo surgery as determined by the treating medical and surgical oncology team. * Demonstrate adequate organ function as defined below: Hematologic Absolute neutrophil count (ANC) \>/= 1.5 X 10\^9/L; Hemoglobin \>/= 9.5 g/dL Platelets \>/= 100 X 10\^9/L PT/INR and PTT \</= 1.5 X ULN. Hepatic Total bilirubin \</= 1.5 X ULN (isolated bilirubin \>1.5 X ULN is acceptable if bilirubin is fractionated and direct bilirubin \<35%) AST and ALT Albumin \</= 2.5 X ULN 1 \>/=2.5 g/dL Renal Creatinine OR Calculated creatinine clearance OR 24-hour urine creatinine clearance \</=1.5 X ULN 2 \>/= 50 mL/min \>/= 50 mL/min. * The individual methods of contraception and duration should be determined in consultation with the investigator. * Women must not be breastfeeding.

Exclusion criteria
