About this study
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.

|---|---|---|
| NSCLC patients with EGFR mutation | Experimental | 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. This cohort will be compared to matched EGFR patients previously analyzed by our group.
Analysis of paired samples from this study will allow a dissection of events acquired through therapy, specifically which component of the combination therapy may be driving selection of the mutations in comparison with the control group without TTFields.

What is being measured
The primary outcome is the main question the study is designed to answer.
Molecular ctDNA characterization under concomitant TTFields therapy - cohort A (EGFR)
The primary outcome measure will be the rate of new somatic mutation detection in circulating tumor DNA (ctDNA) using Next Generation Sequencing (NGS) in patients receiving concurrent TTFields therapy. The measure will be reported as the percentage of patients showing new somatic mutations upon progression of their disease following TTFields treatment.
Measured: 5 years
In vitro peripheral lymphocytes activity characterization under concomitant TTFields therapy - cohort B (under PD-1 inhibitors treatment)
The primary outcome measure will be the evaluation of the impact of combining PD-1 inhibitors with TTFields therapy on peripheral lymphocyte activity using an in vitro assay. Whole blood samples will be collected and the assay will involve the isolation, activation, and labeling of peripheral lymphocytes from patients in cohort B with a panel of antibodies. The analysis will be performed using flow cytometry (FACS) and the longitudinal changes in peripheral lymphocyte activity will be correlated with each patient's response.
Measured: 5 years
Characterization of the impact of TTFields on peripheral lymphocytes proliferation ex-vivo - cohort B (PD-1 inhibitors treatment)
The primary outcome measure will be the quantification of peripheral lymphocyte proliferation in patients receiving PD-1 inhibitors therapy using an in vitro assay. Whole blood samples will be collected and the assay will involve the isolation, labeling, and analysis of peripheral lymphocytes with carboxyfluorescein diacetate succinimidyl ester (CFSE). Proliferation will be measured using flow cytometry (FACS) and the longitudinal changes in peripheral lymphocyte proliferation will be correlated with each patient's response to the therapy in cohort B.
Measured: 5 years
Secondary outcomes (3)
Safety will be assessed by recording adverse events in both cohorts.
Grading of an Adverse Event. The descriptions and grading scales found in the revised NCI Common Toxicity Criteria (CTC) version 4.0 will be utilized for assessing severity of adverse events. If the toxicity is not characterized adequately by the NCI toxicity scale, the investigator will use the adjectives MILD, MODERATE, SEVERE to describe the maximum intensity of the adverse event.
Measured: 5 years
Objective response rate
Objective response rate (ORR) assessed by the investigator, defined as the proportion of the participants with confirmed complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid tumors (RECIST) v1.1, after initiation of study treatment.
Measured: 5 years
DoR
Duration of response, defined as the time interval from the time that the measurement criteria are first met for CR/PR (whichever is first recorded) until the first date that the progressive disease is objectively documented or death. Patients without progressive disease or death will be censored at the last valid response assessment
Measured: 5 years

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
