MA07.06 - Crizotinib in ROS1 Rearranged or MET Deregulated Non-Small-Cell Lung Cancer (NSCLC): Preliminary Results of the METROS Trial (ID 6003)
11:36 - 11:42 | Author(s): A. Delmonte
- Abstract
- Presentation
Background:
Crizotinib is an orally active inhibitor of receptor tyrosine kinases effective in NSCLC with ALK rearrangement. Recent data showed that this agent is dramatically effective in patients with ROS1 rearrangement and at least in some patients with MET deregulation, particularly individuals with exon 14 skipping mutations or with high levels of MET amplification.
Methods:
The METROS trial is a multicenter prospective phase II study designed to assess the efficacy and safety and tolerability of Crizotinib in pretreated metastatic NSCLC with MET amplification or MET exon 14 mutation or ROS1 rearrangement. The co-primary end-point was response rate to crizotinib in two cohorts of patients: cohort A) ROS1+: patients with ROS1 rearrangement; B) MET+: patients with MET amplification defined as ratio MET/CEP7 >2.2 on FISH testing or MET exon 14 skipping mutations. Eligible patients were treated with with crizotinib at the standard dose of 250 mg BID p.o.
Results:
At the time of the present analysis, preliminary data on the MET cohort are available. A total of 249 patients were screened and 18 resulted as MET+ (12 amplified and 6 mutated). Among them, 10 patients (9 amplified and 1 mutated) were included onto the study and received at least one dose of crizotinib, 6 patients were not eligibible beacause of not progressing to front line therapy, whereas 2 patients did not received crizotinib due to rapidly progressive disease. Characteristics of enrolled patients were: median age 68 years (range 39-77); male/female 8/2; ECOG PS 0/1/2: 6/3/1. In 8 cases crizotinib was offered as second-line therapy. All but one patients were current or past smokers. According to RECIST criteria, 2 partial responses and 4 stable disease were so far documented, with an overall disease control rate of 60%. Three patients are still on treatment. Therapy was generally well tolerated, with only 1 patient delaying therapy due to adverse events. Enrollment is still ongoing.
Conclusion:
Preliminary analysis of the METROS trial supports the potential efficacy of crizotinib in patients with MET deregulation, with a favorable toxicity profile. Updated results including median progression-free survival and survival were will be presented at the meeting.

MA08.03 - Osimertinib vs Platinum-Pemetrexed for T790M-Mutation Positive Advanced NSCLC (AURA3): Plasma ctDNA Analysis (ID 4733)
11:12 - 11:18 | Author(s): A. Delmonte
- Abstract
- Presentation
Background:
AURA3 (NCT02151981) is a Phase III, open-label, randomised study assessing the efficacy and safety of osimertinib, a T790M directed EGFR-TKI, vs platinum-based doublet chemotherapy in patients with EGFR T790M-positive advanced NSCLC, whose tumours progressed on previous EGFR-TKI therapy. Concordance between plasma and tissue testing, and efficacy outcomes by baseline plasma T790M status, were evaluated.
Methods:
Eligible patients were randomised 2:1 to osimertinib 80 mg orally once daily or platinum-pemetrexed (pemetrexed 500 mg/m2 + cisplatin 75 mg/m2 or carboplatin AUC5) every three weeks for up to six cycles. Patients were tumour tissue T790M-positive (by cobas[®] EGFR Mutation Test v2) from a biopsy after disease progression prior to study entry. Blood samples were taken at baseline for retrospective analysis of T790M mutation status by plasma ctDNA using the cobas[®] EGFR Mutation Test v2.
Results:
Concordance data are reported in the table. Within the intent-to-treat (ITT) population (n=419), patients plasma T790M-positive and randomised to treatment (n=172) had markedly improved progression-free survival (PFS) by investigator assessment (IA) with osimertinib vs platinum-pemetrexed: hazard ratio 0.42 (95% CI: 0.29, 0.61); median 8.2 vs 4.2 months. Objective response rate (ORR) by IA was also distinctly improved with osimertinib vs platinum-pemetrexed: 77% vs 39% (odds ratio 4.96 [95% CI: 2.49, 10.15]; p<0.001). This is consistent with the ITT population: PFS hazard ratio 0.30 (95% CI: 0.23, 0.41); p<0.001 (median 10.1 vs 4.4 months); ORR 71% vs 31% (odds ratio 5.39 [95% CI: 3.47, 8.48]; p<0.001). Figure 1
Conclusion:
In plasma T790M-positive patients the clinical benefit of osimertinib was superior to platinum-pemetrexed, consistent with the ITT T790M-positive population selected by tumour tissue test. PFS with osimertinib was similar regardless of selection by tissue or plasma T790M-positive status. Based on these, and AURA Phase II data, routine biopsy testing is recommended for patients with a plasma T790M-negative test where feasible.

P1.02-005 - Frequency of Actionable Alterations in EGFR wt NSCLC: Experience of the Wide Catchment Area of Romagna (AVR) (ID 3934)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors have improved the outcome of patients with EGFR-mutated lung adenocarcinoma (ADC). However, EGFR mutation occurred in about only 10-15% of ADC, but other alterations are emerging as potential target of drugs. We analyzed the frequency of potentially targetable driver alterations in a series of advanced EGFR-wild type (wt) NSCLC patients.
Methods:
724 advanced EGFR-wt NSCLC patients enrolled from the Wide Catchment Area of Romagna (AVR) between January 2013 to December 2014 were included in the study. KRAS, BRAF, ERBB2, PIK3CA, NRAS, ALK, MAP2K1, RET and DDR2 mutations were analyzed by Myriapod[®]Lung Status kit (Diatech Pharmacogenetics) on MassARRAY[®] (SEQUENOM[®] Inc, California). ERBB4 was evaluated by direct sequencing and EML4-ALK and ROS1 rearrangements were assessed by immunohistochemistry or fluorescence in situ hybridization.
Results:
331 (45.7%) patients showed at least one alteration. Of these, 72.2%, 6.3%, 3.6%, 1.8%, 2.1% and 1.2% patients had mutations in KRAS, BRAF, PIK3CA, NRAS, ERBB2 and MAP2K1 genes, respectively. Only one patient showed a mutation in ERBB4 gene. EML4-ALK and ROS1 rearrangements were observed in 4.3% and 1.4% of all patients, respectively. The distribution of mutations in relation to gender and smoking habits is reported in the Table. Overlapping mutations were observed in 7 KRAS-mutated patients: 2 (28.6%) patients were also mutated in PIK3CA, 4 (57.1%) showed also an EML4- ALK translocation and one (14.3%) had a ROS1 rearrangement. One (0.3%) patient showed both BRAF and PIK3CA alterations. Correlation analyses between the different mutations and patient outcome are ongoing.

Conclusion:
Driver mutations were detected in about 50% of EGFR wt lung ADC patients. Such alterations could represent potential targets for therapy and could be evaluated in routine multiplexed testing to obtain a wider tumor molecular characterization.

P1.06-006 - Treatment beyond Progression in Patients with Advanced Squamous NSCLC Participating in the Expanded Access Programme (EAP) (ID 5450)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
Response patterns of immunotherapies differ from those seen with other therapies approved for the treatment of tumors. Due to this reason, immunotherapy protocols generally allow patients (pts) to continue treatment beyond investigator-assessed radiographic progressive disease (PD) as long as there is ongoing clinical benefit, but to date no data has been reported regarding treatment beyond PD in routine clinical practice. Here we report the analysis about the subgroup of pts treated beyond initial PD in the italian cohort of nivolumab EAP for pts with squamous non small cell lung cancer (Sq-NSCLC).
Methods:
Nivolumab was available upon physician request for pts aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV Sq-NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks to a maximum of 24 months. Pts included in the analysis had received ≥ 1 dose of nivolumab and were monitored for adverse events (AE) using Common Terminology Criteria for Adverse Events. Patients were allowed to continue treatment beyond initial PD as long as they met the following criteria: investigator-assessed clinical benefit, absence of rapid PD, tolerance of program drug, stable performance status and no delay of an imminent intervention to prevent serious complications of PD.
Results:
With a median follow-up of 5.2 months (range 0-12.9), 363 pts were evaluable for response. Prior to first progression, the objective response rate (ORR) was 14%, with 1 complete response (CR) and 50 (14%) partial responses (PR), and the disease control rate (DCR) was 41%. Sixty-six pts were treated beyond RECIST defined progression, with 23 pts obtaining a non-conventional benefit, meaning a subsequent tumor reduction or stabilization in tumor lesions. In particular, 17 pts obtained a SD and 6 pts obtained a PR. As to July 2016, median overall survival in these pts had not been reached (95% CI: 3.2-4.6) and 6 months and 12 months OS were 75% and 53%, respectively. The safety profile was consistent to what already observed in the general population.
Conclusion:
As already observed in clinical trials, these preliminary EAP data seem to confirm that a proportion of pts who continued treatment beyond PD demonstrated sustained reduction or stabilization of tumor burden, with an acceptable safety profile. Further investigations are warranted in order to better define and identify pts who can benefit from treatment beyond progression.

P1.06-017 - Observational Study on Prolonged Disease Stabilization in Advanced NSCLC EGFR WT/Unknown Patients Treated with Erlotinib in Second Line (ID 4998)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
In advanced NSCLC, erlotinib treatment was shown to improve survival independently of EGFR status and induce high rates of prolonged stable disease (SD). It has previously been reported that, after second-/third-line erlotinib, PFS and OS are long-lasting and similar between patients with SD ≥8 months and those attaining partial/complete response (PR/CR). The present study investigated the clinical value of SD in a real-world setting of advanced NSCLC.
Methods:
This Italian multicenter observational study enrolled patients with stage IIIB-IV NSCLC on second-line erlotinib and wild-type/unknown EGFR mutational status, with SD, CR or PR per RECIST v1.1 lasting for ≥4 weeks. Patients were observed from the beginning of erlotinib for approximately 8 months or until death. Primary end-points were the rate and duration of SD (i.e. time interval from erlotinib start to the last evidence of SD by RECIST) or CR+PR. Secondary end-points were OS and PFS (i.e. time interval from the erlotininb start to the first evidence of progression), estimated by the Kaplan-Meier method and calculated by response duration or disease stabilization. Adverse events occurring during the observation period were also recorded.
Results:
At the cut-off date of 30/04/16, 144/172 (83.7%) enrolled patients were evaluable for response (mean age 69.1 years, 61.8% males). At the start of erlotinib treatment, 85.4% were non-smokers, 89.6% had an ECOG-PS of 0-1, and 84.7% had stage IV NSCLC (83.3% adenocarcinoma and 11.8% squamous cell carcinoma). Following second-line erlotinib, 82.6% (119/144) of patients achieved SD and 17.4% (25/144) PR. Notably, SD was maintained for ≥8 months in 27% (39/144) of cases. At the end of the observation period, 12 (8.3%) patients had deceased, none with SD ≥8 months. Median OS had not been reached by the entire population. According to SD duration, median OS was 4.3 months if <2 months, 6.8 if between 2 and 5 months, and not reached if ≥5 months or if PR. Median PFS was 9.0 months in the entire population, 8.7 among patients with SD and 10.8 with PR. According to SD duration, PFS was 1.4 if <2 months, 4.4 months if between 2 and 5 months, 7.5 if between 5 and 8 months and 10.5 if ≥8 months. No unexpected toxicities were observed.
Conclusion:
In advanced NSCLC, second-line erlotinib yielded a high rate of SD, lasting ≥8 months in 27% of cases, with PFS similar to PR patients and low mortality rate.

P2.03b-063 - Molecular Profiling in Advanced Non-Small-Cell Lung Cancer: Preliminary Data of an Italian Observational Prospective Study (ID 4529)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
Molecular profiling of advanced non-small-cell lung cancer (NSCLC) is recommended according to patients’ histological and clinical features. Despite the existence of national guidelines, routine care is still heterogeneous. Aim of this observational study was to obtain prospectively a clinical practice picture of molecular testing and therapeutic choices in advanced NSCLC patients.
Methods:
Newly diagnosed metastatic or recurrent NSCLC patients enrolled in 38 Italian centres, from November 2014 to November 2015, have been included in the study. Baseline information were collected about molecular profiling performed and therapies.
Results:
A total of 1787 patients were enrolled (64% males, 36% females; median age 67 years-old; 22% never smokers, 31% current smokers, 47% former smokers; 75% adenocarcinoma, and 73% with PS ECOG 0 or 1). The 73.9% of diagnosis was histological, while 26.1% was cytological. 1382 (77%) patients were tested for one or more molecular analysis during the history of disease, for a total of 3532 molecular tests. Only 405 patients did not receive any molecular test. 32.3% of patients presented a genetic alteration: EGFR mutation was reported in 17.8% of cases (319/1787), ALK translocation in 8.8% (82/926), KRAS mutation in 31.9% (154/482), MET amplifications in 15.8% (10/63), BRAF mutations in 3.7% (9/241), ROS1 translocation in 4% (11/269), HER2 mutation in 3.3% (3/89) of cases and FGFR alteration was found in 3 cases (only 15 tested). Considering patients younger than 45 years, never smokers and females, an EGFR mutation was detected in 25.4%, 43.5% and 30.6%, respectively. While 15.6%, 9.5% and 6.3% were ALK rearranged, respectively. For patients receiving an EGFR tyrosine-kinase inhibitor as first-line treatment, among those whose data are evaluable (79.2%), the median interval from diagnosis to first-line was 35 days. EGFR mutated patients received first-line erlotinib, gefitinib and afatinib in 9.4%, 39.1% and 33.8% of cases, respectively. At time of analysis, ALK-rearranged patients received an ALK inhibitor (crizotinib, alectinib or ceritinib) as first and/or second-line in 71.9% of cases. 29.3% of all patients received a maintenance therapy, mainly with pemetrexed (91.2% of cases).
Conclusion:
Routine molecular assessing is properly performed according to the national guidelines. A selection bias in including only those patients performing molecular tests, may explain the high proportion of patients with a molecular alteration. The low number of patients tested for ALK could be partially related to the impossibility to prescribe Crizotinib in first- line. In more than 70% of cases EGFR mutated patients received gefitinib or afatinib as first-line treatment.

P3.02b-006 - Role of TP53 Mutations in Determining Primary Resistance to First-Line Tyrosine Kinase Inhibitors in EGFR-Mutated NSCLC Patients (ID 3861)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
Patients with non-small-cell lung cancer (NSCLC) carrying specific mutations at epidermal growth factor receptor (EGFR) gene are usually sensitive to treatments with tyrosine kinase inhibitors (TKIs). However, not all EGFR-mutated patients respond equally to TKI treatments, and approximately 20-30% show primary resistance. Although the mechanisms responsible for acquired resistance are known, those responsible for primary resistance are not completely understood. In this study we aimed to assess the role of TP53 mutations in a cohort of advanced EGFR-mutated NSCLC patients receiving first-line TKIs. We analyzed TP53 gene status in relation to outcome in terms of overall response rate, disease control rate (DCR), response duration, progression free survival (PFS) and overall survival (OS).
Methods:
We retrospectively analyzed 136 patients with advanced EGFR-mutated NSCLC treated with first-line TKIs from January 2012 to April 2015. Exons 5-8 of TP53 gene were amplified by PCR and sequenced by direct sequencing on 123 patients. DCR was defined as the sum of complete response, partial response and stable disease. The survival endpoints examined were PFS and OS. PFS was defined as the time from start of first-line treatment to disease progression or death, whichever occurred first. OS was defined as the time from start of first-line treatment to death.
Results:
TP53 mutations were observed in 37 (30.1%) patients:10 (27.0%), 6 (16.2%), 9 (24.3%) and 12 (32.4%) in exons 5, 6, 7 and 8, respectively. DCR was 70% in TP53-mutated patients compared to 88% in TP53-wt patients (relative risk, RR: 3.17 [95% CI 1.21-8.48], p=0.019). In particular, a 42% DCR was observed in patients with TP53 exon 8 mutation compared to 87% in exon 8 wt patients (RR 9.6 [2.71-36.63], p<0.001). Shorter median PFS and OS were observed in patients with TP53 exon 8 mutations compared to other patients (4.2 months vs 12.5 months [p=0.058] and 16.2 months vs 32.3 months [p=0.114], respectively); these differences became significant in the subgroup of patients with EGFR exon 19 deletion (4.2 months vs 16.8 months [p<0.001] and 7.6 months vs not reached [p=0.006], respectively), hazard ratio (HR) 6.99 (95% CI 2.34-20.87, p<0.001) and HR 4.75 (95% CI 1.38-16.29, p=0.013), respectively.
Conclusion:
TP53 mutations, in particular exon 8 mutations and those defined as nondisruptive, reduce responsiveness to TKI treatment and induce a worse prognosis in EGFR-mutated NSCLC patients, especially in those carrying exon 19 deletions.

P3.02b-035 - Cell Free Tumor DNA to Monitor Response to Tyrosine Kinase Inhibitors in Patients with EGFR-Mutant Non-Small Cell Lung Cancer (ID 4038)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
Treatment with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) has improved outcome of EGFR mutant non-small-cell lung cancer (mEGFR-NSCLC) patients. Monitoring the presence of EGFR sensitizing and resistance (such as T790M) mutations in response to treatment may have a clinical impact on the therapeutic strategy. Detecting these alterations in circulating free tumor DNA (cftDNA) can be an easier and more safe way to obtain information about the EGFR mutational status.
Methods:
Analyses have been conducted in NSCLC patients with a tissue-confirmed EGFR mutation, treated in first-line setting with TKIs. EGFR-sensitive and EGFR exon 20 mutations were analyzed in cftDNA extracted from plasma collected at baseline, after 8 and 20 days’ treatment, and every 4 months of therapy until progression. EGFR analyses were performed using PANAmutyper kit (PANAGENE).
Results:
Of the 16 mEGFR-NSCLC patients treated with first-line TKIs to date (4 with gefitinib, 2 with erlotinib and 10 with afatinib), 9 (56%) showed EGFR-sensitivity mutation at baseline in cftDNA: 6 had an exon 19 deletion, 1 an exon 21 L861Q mutation and 2 an exon 21 L858R mutation synchronous to exon 20 mutations (one insertion and one T790M point mutation). In these 2 last patients, exon 20 mutations were not identified in tumor tissue. The baseline mutation became undetectable in cftDNA in all the 6 patients with EGFR exon 19 deletion at different time point from the beginning of TKIs: in 5 patients after 21 days and in 1 after 8 days. All these patients had partial response at the first radiological evaluation. The subject harboring EGFR L858R mutation synchronous to exon 20 insertion was responsive to TKI and showed the disappearance of exon 20 insertion in cftDNA a the first clinical evaluation, whereas EGFR L858R disappeared after 4 cycles of treatment. Patient with EGFR L858R and T790M didn’t respond to TKI and progressed after 2 months of treatment. At present 3 out of 9 patients progressed but only one showed appearance of T790M in cftDNA during TKI. In the 7 mEGFR-NSCLC with undetectable cftDNA mutation at baseline no changes were seen during treatment.
Conclusion:
EGFR mutation analysis in cftDNA could give important information concerning the activity of TKIs. In particular the disappearance of mutation in cftDNA may be an early parameter of response that has to be validated in prospective trials. Moreover, cftDNA may give integrative information with respect to that obtained from tissue analysis, bypassing the problem of tumor heterogeneity.

P3.02c-092 - Nivolumab in Multi-Treated Patients with Advanced Sq-NSCLC: Data from the Italian Cohort of Expanded Access Programme (EAP) (ID 4792)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
The prognosis of patients with advanced Sq-NSCLC worsens with the increase of the number of treatment linesand no effective therapeutic options were available for those refractory patients so far.Nivolumab demonstrated significant benefits against the SoC docetaxel in 2[nd] line treatment of advanced sq-NSCLC. In the real life experience of the EAP we could assess the clinical activity and tolerability of nivolumab not only in patients treated in 2[nd] line but also in patients who had received at least 2 lines of therapy prior than nivolumab.
Methods:
Nivolumab was provided upon physician request for patients aged ≥18 years who had relapsed after a minimum of 1 prior systemic treatment for stage IIIB/stage IV Sq-NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks for <24 months. Pts included in the analysis had received ≥1 dose of nivolumab and were monitored for adverse events (AEs) using Common Terminology Criteria for Adverse Events (version 4.03).
Results:
210 patients, corresponding to 56.4% of the entire Italian cohort (n=372), received nivolumab after at least 2 prior lines of chemotherapy in the EAP: 120 (57.1%), 69 (32.9%) and 21 (10%) had received 2, 3 and > 3 prior lines of therapy, respectively. Response was evaluable in 204 patients: with a median number of 8 doses (range, 1–24) and a median follow-up of 5.1 months, the disease control rate was 47%, with 3 patients (1%) in complete response, 30 patients (14%) in partial response and 66 patients (32%) in stable disease. 36 patients (17%) were treated beyond RECIST-defined progression, with 11 of them achieving disease control. As of April 2016, median progression-free survival and median overall survival were respectively 3.8 and 11.2 months. 117/210 patients (55.7%) discontinued treatment for any reason except toxicity; 11 out of 210 (5.2%) discontinued due to AEs.
Conclusion:
These findings showed that nivolumab provided clinical activity with a manageable safety profile in patients with advanced, refractory Sq-NSCLC. These data suggest that nivolumab can be a treatment option for patients failing more than one line of chemotherapy.

P3.02c-094 - Italian Nivolumab Advanced Squamous NSCLC Expanded Access Program: Efficacy and Safety in Patients with Brain Metastases (ID 5144)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
The prognosis of NSCLC patients (pts) with brain metastases is still quite poor. These pts usually do not meet the inclusion criteria to be enrolled in clinical trials. Nivolumab Italian Expanded Access Program (EAP) allowed this subpopulation of pts to be included, providing the opportunity to evaluate safety and efficacy of nivolumab treatment in pts with brain metastases.
Methods:
upon physician written request, nivolumab was provided to pts who met the following inclusion criteria: aged ≥18 years, who had received a diagnosis of squamous NSCLC, and who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV squamous NSCLC. Nivolumab is administered intravenously at the dose of 3 mg/kg every 2 weeks for a maximum duration of 24 months. We describe efficacy and safety of nivolumab in pts who received at least one dose. Adverse events were monitored using Common Terminology Criteria for Adverse Events.
Results:
from our cohort of 372 patients diagnosed with squamous NSCLC, we report the results of 38 (10.2%) pts with treated and asymptomatic brain metastases. In these pts, with median follow-up of 4.5 months and median number of doses of 6 (range, 1–18), disease control rate was 47.3%, including 1 complete response, 6 partial responses and 11 stable diseases. Treatment beyond RECIST defined progression was allowed, under protocol defined circumstances, in 4 pts. Median progression-free survival was 5.5 months, and overall survival was 6.5 months (data lock of April 2016). Out of the 38 pts included, only 1 discontinued treatment due to AE (2.6%), whereas 21 pts (55.3%) discontinued treatment for non-toxicity related reasons.
Conclusion:
although preliminary, these results demonstrate efficacy of nivolumab in squamous NSCLC pts with brain metastases. Safety of nivolumab in these pts is consistent with previously reported data from clinical trials. These results suggest nivolumab could be beneficial in this subpopulation of pts with unfavourable prognosis.

P3.02c-095 - Italian Nivolumab Expanded Access Programme: Efficacy and Safety Data in Squamous Non Small Cell Lung Cancer Patients (ID 5159)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
Nivolumab monotherapy has shown survival benefit in patients (pts) with melanoma, lung cancer, renal cell carcinoma and head and neck cancer. The experience of pts and physicians in routine clinical practice is often different from those in a controlled clinical trial setting. Here, we report efficacy and safety of nivolumab monotherapy in pts with squamous non small cell lung cancer (Sq-NCSLC) treated in the nivolumab Expanded Access Programme in Italy.
Methods:
Nivolumab was available upon physician request for pts aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV Sq-NSCLC. Nivolumab 3 mg/kg wass administered intravenously every 2 weeks to a maximum of 24 months. Pts included in the analysis had received at least 1 dose of nivolumab and were monitored for adverse events (AE) using Common Terminology Criteria for Adverse Events.
Results:
In total, 371 Italian pts participated in the EAP across 96 centres and 363 patients were evaluable for response. With a median follow-up of 5.2 months (range 0-12.9) and a median of 7 doses, the best overall response rate (BORR) was 18%, with 3 complete responses (CR) and 62 partial responses (PR), and the disease control rate (DCR) was 47%. DCR was comparable among pts regardless previous lines of therapy, brain metastasis, age and smoking habits. A non-conventional benefit was observed in 23 (17 SD and 6 PR) out of 66 pts treated beyond RECIST defined progression. As of April 2016, median progression-free survival and median overall survival were 3.9 (95% CI: 3.2-4.6) and 9.1 (95% CI: 6.7-11.5) months, respectively. Regarding the safety profile, 267 out of 371 pts (72%) had at least one AE of any grade, considered to be drug-related in 106 pts (29%). Grade 3/4 AE were reported in 66 pts and considered to be drug-related in 20 pts (5%). AE were generally manageable following the specific guidelines.
Conclusion:
To date, this is the largest clinical experience with nivolumab in a real-world setting. These preliminary EAP data seems to confirm the efficacy and safety data of nivolumab from registrational trials, supporting its use in current clinical practice for pre-treated pts with Sq-NCSLC.

P3.02c-096 - Use of Nivolumab in Elderly Patients with Advanced Squamous NSCLC: Results from the Italian Expanded Access Programme (EAP) (ID 5706)
14:30 - 14:30 | Author(s): A. Delmonte
- Abstract
Background:
The efficacy and safety of nivolumab in patients with squamous NSCLC (sq-NSCLC) have been demonstrated in several trials including the phase 3, randomized, controlled CheckMate 017 study whose results led to the approval of the product for this indication. However, data on the use of nivolumab in the real world setting is still limited and collecting it is paramount. The Italian nivolumab EAP for sq-NSCLC represents an important source of information in that respect. The current analysis describes results of the use of nivolumab in the group of EAP patients aged >75 years.
Methods:
Nivolumab was provided upon physicians’ request for patients aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV Sq-NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks for <24 months. Patients included in the analysis received ≥1 dose of nivolumab and were monitored for adverse events (AEs) using Common Terminology Criteria for Adverse Events.
Results:
70 out of 372 (18.8%) patients with advanced Sq-NSCLC participating in the EAP in Italy were ≥75 years old and 68 of them were evaluable for response. With a median number of doses of 7 (range, 1–20) and a median follow-up of 4.7 months, the disease control rate was 42.9%, including 13 patients with a partial response and 17 with stable disease. 16 pts were treated beyond RECIST-defined progression and 5 of them achieved disease control. As of April 2016, the median progression-free survival and median overall survival among those elderly patients were 3.2 and 7.6 months, respectively. Among 70 pts, 41 pts (58.6%) discontinued treatment for any reason except toxicity; 8 out of 70 discontinued due to AE (11.4%).
Conclusion:
This analysis, conducted on elderly patients with sq-NSCLC in a real life setting, suggests that nivolumab is an effective and well tolerated treatment for this special population.
