MA12.06 - STELLAR – Final Results of a Phase 2 Trial of TTFields with Chemotherapy for First-Line Treatment of Malignant Pleural Mesothelioma (ID 13806)
11:05 - 11:10 | Presenting Author(s): Giovanni L Ceresoli
- Abstract
- Presentation
Background
Tumor Treating Fields (TTFields) are an anti-mitotic, regional treatment modality, utilizing low intensity alternating electric fields delivered non-invasively to the tumor using a portable, medical device. In-vitro, human mesothelioma cells were highly susceptible to TTFields. TTFields have been shown to significantly extend survival of patients with glioblastoma when added to chemotherapy.
a9ded1e5ce5d75814730bb4caaf49419 Method
The trial accrued 80 patients with unresectable, previously untreated mesothelioma. Patients were treated with continuous 150 kHz TTFields (>18h/day) in combination with pemetrexed and cisplatin or carboplatin (at standard dosing). Inclusion criteria included ECOG PS of 0-1, pathologically proven mesothelioma and at least one measurable lesion according to modified RECIST criteria. Patients were followed q3w (CT scan q6w) until disease progression. The primary endpoint was overall survival (OS) and secondary endpoints were response rate, progression free survival (PFS) and toxicity. This prospective, single arm study assumed an historical control with a median survival of 12.1 months (Vogelzang et al. 2003). The sample size provides 80% power with a two-sided alpha of 0.05 to detect an increase in median OS of 5.5 months.

All 80 patients were enrolled between 2016 and 2017, with a minimum follow up of 12 months. Median age was 67 (range 27-78), 84% were male and 56% smokers. 16% (13 patients) had metastatic disease and 44% (35 patients) had an ECOG PS of 1. 66% (53 patients) had epithelioid histology. Compliance with TTFields was 68% (16.3 hours/day) during the first 3 months of therapy and 63% (50 patients) received carboplatin.
Median OS was 18.2 months (95% CI 12.1-25.8) compared to 12.1 months in the historical control. Median PFS was 7.6 months (95% CI 6.7-8.6) compared to 5.7 months in the historical control. Partial responses were seen in 40.3% of patients and clinical benefit (PR+SD) was seen in 97.2% of patients. No device-related serious adverse events (AEs) were reported. Expected TTFields-related dermatitis was reported in 46% (37 patients). Only 4 patients (5%) had grade 3 dermatitis. The following grade 3-4 systemic AEs were reported in >3% of patients: hematological AEs (15%) and fatigue (4%).
8eea62084ca7e541d918e823422bd82e Conclusion
The study met its primary endpoint of significant extension of survival for previously untreated mesothelioma patients. Secondary efficacy endpoints were also improved compared to historical control. The study demonstrated no safety concerns for the combination of TTFields to the thorax together with standard chemotherapy. These results support the addition of TTFields to standard chemotherapy in the treatment of first-line malignant pleural mesothelioma.

P1.01-73 - Preliminary Results of the SENECA (SEcond Line NintEdanib in Non-Small Cell Lung CAncer) Trial: An Italian Experience. (ID 13281)
16:45 - 18:00 | Author(s): Giovanni L Ceresoli
- Abstract
Background
Nintedanib is a multi-target small-molecule with anti-angiogenetic activity which confers longer progression free survival (PFS) and overall survival (OS) as second-line combination treatment with docetaxel versus standard-of-care, in non-squamous non-small cell lung cancer (nsNSCLC) patients, giving to rapidly progressing patients the greatest survival benefit. Considering the higher tolerability of weekly docetaxel than docetaxel q3wks in the real-life, the SENECA trial, a phase IIb, open label, Italian multicentre study, aims to evaluate whether treatment with nintedanib and docetaxel could be effective and safe as second-line option in nsNSCLC patients with the two different schedules.
a9ded1e5ce5d75814730bb4caaf49419 Method
Patients from eighteen Italian oncologic centres, with stage IIIB/IV non-oncogene addicted nsNSCLC patients, progressing after first-line chemotherapy, have been treated with docetaxel (T1: 33 mg/mq on days 1 and 8 in a 21-days cycle; T2: 75 mg/mq q3wks) plus continuous oral nintedanib, with the possibility of maintenance in case of stabilization or response. Primary endpoint was PFS (by investigator’s assessment), while secondary endpoints included OS, safety and quality-of-life. Study stratifies patients into two cohorts according to relapse-timing (within or over 3 months) from end of first-line chemotherapy.
4c3880bb027f159e801041b1021e88e8 Result
From January 2016 to data cut-off, on 30th March 2018, 197 patients have been evaluated: 30 were registered as screening failures, mainly for contraindications to nintedanib use. The 167 patients considered in this preliminary analysis had a median age of 63.4 years (range 35-86), were predominantly male (68.9%), smokers or former-smokers (84.4%) and with ECOG-performance status 0 (72.5%). According to investigator’s choice, 82 patients have been treated with T1 docetaxel (49.1%), 85 (50.9%) with T2 docetaxel (median docetaxel treatment 3.5 and 3.7 21-days cycles, respectively). No significant differences in median PFS have been observed between T1 and T2 (3.83 vs 4.32 months, respectively; HR 0.889 [95% IC 0.598-1.321], p-value=0.559). After a median follow-up of 7.28 months (standard deviation=5.55), a trend of similar OS has emerged in both T1 and T2 (6.63 vs 7.91 months, respectively; HR 0.770 [95% IC 0.484-1.225], p-value=0.270). Survival data of relapse-timing cohorts are not yet mature. Commonest toxicities in T1 and T2 were: fatigue (53.6% vs 65.9%, respectively), diarrhea (50.0% vs 47.0%), afebrile neutropenia (13.4% vs 52.9%) and ALT elevation (29.3% vs 20.0%).
8eea62084ca7e541d918e823422bd82e Conclusion
The SENECA trial is a real-life Italian experience, whose preliminary results confirm the efficacy and safety of second-line treatment with nintedanib and docetaxel for nsNSCLC patients, regardless from docetaxel schedule, suggesting higher toxicities for docetaxel q3wks.

P2.06-05 - TTFields Applied to the Torso and Upper Abdomen: Safety Meta-Analysis of 176 Patients from four Phase I-II Trials (ID 12923)
16:45 - 18:00 | Presenting Author(s): Giovanni L Ceresoli
- Abstract
Background
Tumor Treating Fields (TTFields), a non-invasive, antimitotic treatment delivered through transducer arrays, is approved for glioblastoma. The phase 3 trial in newly diagnosed glioblastoma showed no significant increase in systemic adverse events (AEs) except for localized dermatitis underneath the arrays. The safety of TTFields was investigated in four phase I-II non-brain malignancies: non-small-cell lung cancer (NSCLC), malignant pleural mesothelioma (MPM), pancreatic cancer and ovarian cancer.
a9ded1e5ce5d75814730bb4caaf49419 Method
The TTFields phase I-II studies analyzed were: EF-15 (n=41, advanced NSCLC with pemetrexed), PANOVA (n=40, advanced pancreatic adenocarcinoma with gemcitabine +/- nab-paclitaxel), STELLAR (n=64, MPM with platinum/ pemetrexed) and INNOVATE (n=31, recurrent ovarian carcinoma with weekly paclitaxel). TTFields were applied for 12-18 hours at 150-200 kHz per tumor histology. Patients received standard-of-care systemic chemotherapy for their disease. Severity and frequency of AEs and association with TTFields were evaluated (CTCAE V 4.0).
4c3880bb027f159e801041b1021e88e8 Result
Patient median age was 69 years (range 41-81), 73 (49-81), 68 (43-78) and 60 (45-77) for EF-15, PANOVA, STELLAR and INNOVATE, respectively. Patients were ECOG status 0-1, except for 7 patients in EF-15 with ECOG 2. Observed toxicities were mostly related to underlying disease or standard chemotherapy. Grade 1-2 gastrointestinal (GI) toxicities were: constipation (16%), diarrhea (14%), nausea (27%) and vomiting (13%). Grade 1-2 general disorders such as asthenia were common but less than 20%. Grade 3-4 dyspnea was observed in 6% of NSCLC patients. No clinically significant cardiac AEs were observed and mild arrhythmias were observed in less than 2% of patients. The common TTFields-related AE was dermatitis under the transducer arrays (50% Grade 1-2; 6% Grade 3 dermatitis and 7% Grades 1-2 pruritus). Dermatologic AEs managed using published guidelines were fully resolved.
8eea62084ca7e541d918e823422bd82e Conclusion
Treatment of solid tumors with TTFields (150-200 kHz) to the lungs, pleura, abdomen and upper pelvis did not result in treatment-related pulmonary, cardiac, hematological or gastrointestinal toxicity. Expected dermatological toxicity (50%) beneath the transducer arrays was easily managed.

PL02.09 - Nintedanib + Pemetrexed/Cisplatin in Patients with Unresectable MPM: Phase III Results from the LUME-Meso Trial (ID 11192)
09:15 - 09:25 | Author(s): Giovanni L Ceresoli
- Abstract
- Presentation
Background
Nintedanib targets VEGFR 1–3, PDGFR α/β, FGFR 1–3, Src and Abl kinases, all implicated in malignant pleural mesothelioma (MPM) pathophysiology. This global Phase II/III, randomised, double-blind study investigated pemetrexed/cisplatin in combination with nintedanib or pemetrexed/cisplatin in combination with placebo, followed by nintedanib or placebo maintenance, in patients with unresectable MPM. In the double-blind, randomised Phase II part, nintedanib plus pemetrexed/cisplatin improved PFS vs placebo (HR=0.56; 95% CI: 0.34–0.91; p=0.017; median 9.4 vs 5.7 months).
In Phase III, chemotherapy-naïve patients with epithelioid MPM (ECOG PS 0–1) were randomised 1:1 to receive up to six cycles of pemetrexed (500 mg/m2)/cisplatin (75 mg/m2) on Day 1, plus nintedanib (200 mg bid) or matched placebo on Days 2–21. After combination treatment, patients without disease progression received nintedanib or placebo maintenance. The primary endpoint (PFS by investigator assessment) and key secondary endpoint (OS) were planned to be analysed by hierarchical testing, with an interim OS analysis at the time of the primary PFS analysis. PFS was also assessed by independent central review. Based on the assumed treatment effect (HR=0.63), the study had 90% power to detect a statistically significant and clinically meaningful improvement in PFS.
In total, 458 patients were randomised. Baseline patient characteristics and oncological history were similar between treatment arms. Median duration of nintedanib or placebo administration was 5.3 and 5.1 months, respectively. After 250 events, there was no difference in PFS between nintedanib and placebo arms (HR=1.01; 95% CI: 0.79–1.30; p=0.91; median 6.8 vs 7.0 months, respectively). PFS by central independent review was similar (242 events; HR=0.99; 95% CI: 0.77–1.28; p=0.96; median 6.8 months in each arm). In the interim OS analysis (127 deaths [28% of events]), median OS was 14.4 vs 16.1 months (nintedanib vs placebo; HR=1.12; 95% CI: 0.79–1.58; p=0.54). There were no unexpected safety findings. The proportion of patients with Grade ≥3 AEs was higher with nintedanib than with placebo (72% vs 62%). The most frequently reported Grade ≥3 AE by medical concept in both treatment arms was neutropenia (nintedanib: 32%; placebo: 24%). The proportion of deaths due to serious AEs was 4.0% (nintedanib) and 7.5% (placebo).
The primary endpoint of the Phase III part of LUME-Meso was not met ‒ Phase II findings were not confirmed. The reported safety profile was consistent with the known safety profiles of nintedanib and pemetrexed/cisplatin.
