10. Preserved organ functions defined by:

    * Absolute neutrophil count ≥ 1,000;

Exclusion Criteria

1. Previous treatment lines with immunotherapy (immune checkpoint inhibitors).
2. Pregnant or breastfeeding individuals.
3. Limiting comorbidity, in the opinion of the investigator.
4. Active infection.
5. Major surgery within the last 4 weeks.
6. Functional class II or greater heart failure.
7. Myocardial infarction or stroke within the last 6 months.
8. History of pulmonary fibrosis or pneumonitis.
9. Autoimmune diseases, except for patients with vitiligo and/or controlled thyroid/hypothyroidism without the use of immunosuppressors.
10. Second invasive primary tumor diagnosed in the last 3 years and/or with active disease, except for localized skin tumors (non-melanoma) that have been treated with curative intent.
11. Patients with prolonged QT interval.
12. Uncontrolled Central Nervous System (CNS) metastases. Patients who have previously received local treatment, such as radiotherapy, will be eligible if clinical and radiological stability is demonstrated in the 2 weeks prior to the start of treatment.
