Overview
Low intensity, intermediate frequency (100-300 kHz) alternating electric fields, also known as Tumor Treating Fields (TTFields) were found to have a profound inhibitory effect on the growth rate of a variety of human cancer cells. Previous study showed anti-tumor activity in respect of melanoma, glioblastoma (GBM), breast carcinoma and NSCLC cell lines. This study aims to assess the impact of TTFields on NSCLC though the understanding of tumor evolution and peripheral lymphocytes activity and proliferation. Concomitant to drug therapy, patients will receive treatment with Tumor Treating Fields (TTFields), generated by the medical device NovoTTF-200T with a recommended duration of minimum 18 h a day. TTFields administered using insulated transducer arrays applied to the skin surrounding the region of a malignant tumor. 50 patients will be recruited according to the study design in two cohorts and will receive TTFields therapy: Cohort A: Adult NSCLC EGFR positive mutation. Cohort B: Adult NSCLC patients to be treated with PD-1 inhibitors. The cohort A will focus on the clonal evolution in EGFR mutated lung cancer patients by using circulating tumor DNA (ctDNA) analysis of paired baseline and end-of-treatment (EOT) plasma samples. The cohort B will study the impact of TTField on the profile, activity, and proliferation of peripheral lymphocytes. Lymphocytes will be purified from whole blood samples for the profile, proliferation, and activity analyzed by FACS. Treatment with TTFields will be administered until progressive disease, unacceptable toxicity1, withdrawal of consent or death. After the end of treatment, the patients will be followed until data cutoff date or 2 years after the last patient had entered the study.

Primary outcome measures
- Molecular ctDNA characterization under concomitant TTFields therapy - cohort A (EGFR) [Time frame: 5 years]
- In vitro peripheral lymphocytes activity characterization under concomitant TTFields therapy - cohort B (under PD-1 inhibitors treatment) [Time frame: 5 years]
- Characterization of the impact of TTFields on peripheral lymphocytes proliferation ex-vivo - cohort B (PD-1 inhibitors treatment) [Time frame: 5 years]
Secondary outcome measures (3)
- Safety will be assessed by recording adverse events in both cohorts. [Time frame: 5 years]
- Objective response rate [Time frame: 5 years]
- DoR [Time frame: 5 years]
