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): Alessandro Morabito
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.6f8b794f3246b0c1e1780bb4d4d5dc53

PL02.03 - Brigatinib vs Crizotinib in Patients With ALK Inhibitor-Naive Advanced ALK+ NSCLC: First Report of a Phase 3 Trial (ALTA-1L) (ID 11155)
08:30 - 08:40 | Author(s): Alessandro Morabito
Brigatinib has robust efficacy in crizotinib-resistant ALK+ NSCLC, exhibiting median progression-free survival (mPFS) of 16.7 months. We report results of the first interim analysis from the ALTA-1L study of brigatinib vs crizotinib in ALK TKI-naive, ALK+ NSCLC (NCT02737501).
This open-label, multicenter study enrolled patients with stage IIIB/IV ALK+ NSCLC based on local ALK testing (FDA approved/other). Eligible patients had ECOG PS 0–2, ≤1 prior systemic therapy for locally advanced/metastatic NSCLC, and no prior ALK inhibitor. Asymptomatic CNS metastases were allowed. All patients had systematic CNS imaging. Patients were randomized 1:1 to brigatinib 180 mg QD with 7-day lead-in at 90 mg or crizotinib 250 mg BID. Primary endpoint: blinded independent review committee (BIRC)-assessed PFS (RECIST v1.1). Secondary efficacy endpoints included BIRC-assessed objective response rate (ORR), intracranial ORR (iORR), and intracranial PFS (iPFS). Interim analyses were planned at 50% and 75% of planned PFS events (n=198).
275 patients were randomized (brigatinib/crizotinib, n=137/138); median age (years) 58/60. 26%/27% received prior chemotherapy for advanced disease, and 29%/30% had baseline brain metastases. At data cut-off (19 February 2018), median follow-up brigatinib/crizotinib: 11.0/9.25 months; with 99 PFS events, brigatinib met the prespecified threshold for statistical superiority vs crizotinib in the primary endpoint, BIRC-assessed PFS (HR 0.49, 95% CI 0.33–0.74, log-rank P=0.0007); brigatinib mPFS was not reached (95% CI NR–NR) vs crizotinib 9.8 months (95% CI 9.0–12.9). Investigator-assessed PFS HR 0.45 (95% CI 0.30–0.68), log-rank P=0.0001. Table shows additional efficacy data. Most common treatment-emergent AEs grade ≥3: brigatinib: increased CPK (16.2%), increased lipase (13.2%), hypertension (9.6%); crizotinib: increased ALT (9.5%), AST (5.8%), and lipase (5.1%). Any grade ILD/pneumonitis: brigatinib, 3.7%; crizotinib, 2.2%. Discontinuations due to AE (brigatinib/crizotinib): 11.8%/8.8%.
Brigatinib showed a statistically and clinically significant improvement in PFS compared with crizotinib in ALK inhibitor–naive ALK+ NSCLC.
