About this trial

The objective of this prospective multicenter study is to evaluate whether the analysis of immunological biomarkers present in circulating extracellular vesicles is associated with the response to anti-PD-1/PD-L1 treatments in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) or unresectable melanoma.

Patients will receive standard-of-care treatment and will be followed according to routine clinical practice. The study involves the collection of four study-specific blood samples at different time points during follow-up, as well as the collection of standard immunohistochemistry results, thoraco-abdomino-pelvic CT scans, and tumor DNA genotyping analyses performed as part of routine care.

The study aims to determine:

* whether baseline biomarkers in extracellular vesicles are associated with response to anti-PD-1/PD-L1 treatment, * how these biomarkers change over the course of treatment, and * to provide exploratory data for the development of predictive immunological response signatures.

Eligibility criteria

Qualifiers

Age ≥18 years.

Histologically confirmed diagnosis of non-small cell lung cancer (NSCLC) or locally advanced/metastatic unresectable melanoma.

Patient scheduled to initiate anti-PD-(L)1 therapy, either as monotherapy or in combination (other immune checkpoint inhibitors, chemotherapy, etc.).

Baseline tumor assessment performed within 28 days prior to enrollment (CT scan of thorax, abdomen, and pelvis) with at least one measurable lesion according to RECIST 1.1 criteria.

Disqualifiers

Prior treatment with immunotherapy.

Presence of EGFR or ALK mutation (applicable only to the lung cohort).

Presence of another synchronous malignancy.

Diagnosis of uveal melanoma.
