MA 01.07 - Lanreotide Maintenance in SCLC Expressing Somatostatine Receptors: Efficacy Results of Multicenter Randomized G04.2011 Trial (ID 8480)
11:40 - 11:45 | Author(s): Francesco Grossi
- Abstract
- Presentation
Background:
SCLC is featured by both a rapid response and progression during/after standard upfront therapy. Thus, maintenance strategies emerged as potential treatment opportunities, although to date all drugs failed to significantly improve prognosis. SCLC cells harbor a neuroendocrine phenotype, frequently expressing somatostatine (SST) receptors. This study aimed to investigate the efficacy of somatostatine (SST) analogue Lanreotide (LAN) as a maintenance strategy for SCLC patients (pts) after response to standard upfront treatment.
Method:
A multicentre, randomized, open-label, no-profit national trial was conducted, randomizing (1:1) SCLC (limited/extended disease, L/ED) pts expressing SST receptors (by SST receptor scintigraphy) with objective response (CR or PR) after upfront platinum-based chemotherapy plus/minus radiotherapy to receive maintenance LAN 120 mg subcutaneously every 28 days, up to progressive disease (PD) for 1 year (Arm A), versus observation (Arm B). Primary end-point was 1-year Progression-Free Survival (PFS). Primary intention-to-treat (ITT) analysis was planned (power: 80%; 2-tailed alpha-error: 5%) after 47 PFS events.
Result:
Seventy-one pts (median age 66 [37-82]; male/female 72/28%; L/ED 39/61%; ECOG-PS 0-1/2 97/3%; previous best response CR/PR 6/94%) were randomized in 9 Italian centers. Median time from diagnosis and end-of-1[st] line to inclusion was 5.7 months (3-160) and 30 days (0-119), respectively. Median number of LAN doses and treatment duration (Arm A) was 4 (1-12) and 83 days (1-392), respectively. With a median follow-up of 9.4 months and 62 events, median PFS was 3.6 (95% CI 3.2-3.9) versus 2.3 months (95% CI 1.7-2.9), for Arm A and B (log-rank p=0.11; HR 1.51, 95% CI 0.90-2.50), with a 1-year PFS of 10.3% versus 7.3%, respectively. At the cox-proportional multivariate modelling, stage (ED versus LD, HR 2.88 [95% CI 1.64-5.04, p<0.0001) and treatment arm (B versus A, HR 1.63 [95% CI 0.97-2.72], p=0.06) were independent predictors for PFS. Median PFS of arm A and B was 7.0 [95% CI <1-13.5] and 3.8 months [95% CI <1-8.6] in LD pts (p=0.21), and 3.0 (95% CI 2.2-3.8) and 2.2 (95% 1.7-2.7) in ED pts (p=0.19). Median OS was 9.5 (95% CI 4.8-14.3) and 4.7 months (95% CI 1.7-16.6), for Arm A and B (log-rank p=0.47), respectively. LAN was well-tolerated: serious treatment-related adverse events were grade 3 abdominal pain and electrolyte disorder in overall 2 pts.
Conclusion:
Although the primary end-point was not met, the overall efficacy of LAN as a maintenance strategy after response to standard upfront treatment for SCLC deserves future investigations, particularly in pts with LD.

MA 10.06 - Real-World Results in Non-Squamous Non-Small Cell Lung Cancer Patients: Italian Nivolumab Expanded Access Programme (ID 9580)
11:35 - 11:40 | Presenting Author(s): Francesco Grossi
- Abstract
- Presentation
Background:
Nivolumab monotherapy has shown survival benefit in patients (pts) with different tumors, including melanoma, lung cancer, renal cell carcinoma, head and neck cancer and Hodgkin lymphoma. Controlled clinical trial setting differs from what experienced by pts and physicians in routine clinical practice. Here, we report efficacy and safety results of nivolumab in pts with non-squamous non-small cell lung cancer (Non-Sq-NSCLC) treated in the Expanded Access Programme in Italy.
Method:
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 non-Squamous NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks to a maximum of 24 months. Pts included in the analysis had received at least one dose of nivolumab and were monitored for adverse events (AE) using Common Terminology Criteria for Adverse Events.
Result:
Overall, 1588 pts were enrolled in the EAP across 168 Italian centers. Baseline characteristics of pts were representative of Non-Sq-NSCLC population, in the advanced disease setting. As of March 2017, median overall survival (OS) was 11 months (10.0-12.0), with a median follow-up of 7.8 months (1-21.9) and a median of 7 doses (1-46). The best overall response rate (BORR) was 18%, including 10 pts (<1%) with complete response and 280 pts (17.6%) with partial response. Stable disease has been defined for 414 pts (26.0%) and totally 274 (17.2%) patients were treated beyond progression. Response rates and survival were comparable among pts regardless age (< and ≥ 75 years), presence of brain metastasis and number of prior therapies. Overall, among 1588 pts, 1254 discontinued treatment for any reason, with only 93 (7%) pts who discontinued treatment due to adverse events, in line with what observed in previous studies.
Conclusion:
To date, this is the largest clinical experience with nivolumab in a real-world setting and these EAP data are in line with what reported in the registrative phase 3 clinical trial. According to these results, nivolumab seems to be an effective and safe therapy for pre-treated patients with non-squamous NCSLC, supporting its use in current clinical practice.

MA 11.11 - Italian Nivolumab Expanded Access Program in Non-Squamous NSCLC Patients: Results in Never Smokers and EGFR Positive Patients (ID 8404)
12:10 - 12:15 | Author(s): Francesco Grossi
- Abstract
- Presentation
Background:
Nivolumab is the first checkpoint inhibitor approved for the treatment of non-Squamous non small cell lung cancer (non-Sq-NSCLC). Although smoking habits are considered a relevant risk factor related to the onset of lung cancer, previous studies showed that current and former smokers patients (pts) treated with nivolumab may have a greater advantage in terms of clinical benefit than never smokers and EGFR mutated. Nevertheless, to date, no definitive conclusion may be drawn and no data are available from a real world setting. Here we report the data from Italian expanded access program (EAP) in the never smoker pts and EGFR mutated pts.
Method:
Nivolumab was provided upon physicians’ request for pts aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV non-Sq-NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks for <24 months. Pts included in the analysis received ≥1 dose of nivolumab and were monitored for adverse events (AEs) using Common Terminology Criteria for Adverse Events.
Result:
Overall, of 1588 patients with non-Sq-NSCLC, smoking history was available for 1430 pts and 305 (21%) were never smokers and, among 1455 pts evaluable for EGFR mutation, 102 (7%) were positive. In the never smoker group, EGFR status was available for 287 pts, with 51 (18%) who harbored an activating EGFR mutation. Among never smokers, with a median follow-up (FU) of 7.0 months (0.1-20.3) and a median of 7 doses (1-38), the best objective response rate (BORR), the disease control rate (DCR) and the median overall survival (OS) were 9%, 42% and 10.0 months (8.1-11.9), respectively. Among all EGFR positive pts, with a median FU of 5.5 months (0.1-21.2) and a median of 6 doses (1-40), the BORR, DCR and median OS were 9%, 30% and 8.3 months (2.2-14.4), respectively. In the never smoker group, EGFR positive pts had 2% ORR, 26% DCR and 5.6 months (3.4-7.8) of median OS. However, it should be considered that these pts had poorer prognostic factors (ECOG performance status, brain metastasis) at baseline.
Conclusion:
These preliminary results represent the first real-life data regarding the efficacy of nivolumab in special subpopulations, including never smokers and EGFR positive pts. These results warrants further studies to evaluate the possible therapeutic options in these pts, also taking into account available alternatives and safety profile.

P1.01-015 - Crizotinib in ROS1 Rearranged or MET Deregulated Non-Small-Cell Lung Cancer (NSCLC): Final Results of the METROS Trial (ID 9454)
09:30 - 09:30 | Author(s): Francesco Grossi
- Abstract
Background:
Crizotinib is the standard of care in NSCLC with ALK rearrangement. Recent data showed that the drug is dramatically effective in patients with ROS1 rearrangement (ROS1[+]), with promising activity also in individuals with MET exon 14 mutations (MET[Ex14]) or MET amplification (MET[FISH+]).
Method:
The METROS is an Italian multicenter prospective phase II trial designed to assess the efficacy and safety of crizotinib in ROS1[+ ]or MET[Ex1][4 ]or MET[FISH][+ ]advanced NSCLC patients who failed at least 1 standard chemotherapy regimen. The co-primary end-point was response rate (RR) in cohort A (ROS1+: centrally confirmed ROS1 rearrangement) and cohort B (MET+: centrally confirmed MET[FISH][+ ]defined as ratio MET/CEP7 >2.2 or locally confirmed MET[Ex1][4]). Eligible patients received crizotinib at the standard dose of 250 mg BID orally.
Result:
At the data cut-off of April 30[th], 2017, both cohorts completed accrual. Among 498 screened patients, 52 accounted for the intent-to-treat population (ITT) and received at least 1 dose of crizotinib. Among them, 26 resulted ROS1[+], 16 MET[FISH][+] and 10 MET[Ex1][4]. Notably, 3 MET[Ex1][4] cases had concurrent KRAS mutation and 1 had concurrent MET gene amplification. No concomitant driver event was detected in the ROS1 cohort. Cohort A included individuals with adenocarcinoma, median age of 55 years (range 29-86), predominantly female (61%) and never smokers (54%). Cohort B included older subjects (median age 68, range 39-78), predominantly male (65%), current/former smokers (77%) and with adenocarcinoma (92%). In both cohorts, the vast majority of patients (85%) presented > 2 metastatic sites and crizotinib was mainly offered as second line treatment (74%). Time from end of first line therapy to crizotinib was 4.1 and 1.6 months for cohort A and B, respectively. In ITT population RR, median progression free-survival (PFS) and overall survival (OS) were 61.5%, 17.2 months and not reached in cohort A and 26.9%, 3.1 months and 5.3 months in cohort B, respectively. For cohort B, responses were observed in both MET[FISH][+] and MET[Ex1][4] (25% and 30%, respectively), with evidence of rapid progression in patients carrying MET[Ex1][4][/KRAS]. At present, for 2 MET+ patients assessment is pending. Therapy was generally well tolerated with no unexpected adverse event.
Conclusion:
The METROS is the first prospective trial specifically conducted in ROS1+ or MET+ deregulated NSCLC. The study confirms remarkable efficacy of crizotinib in ROS1[+] NSCLC. Responses observed in the MET cohort were of short duration confirming aggressiveness of the disease and the urgent needs for innovative therapies.

P1.01-053 - Italian Nivolumab Expanded Access Programme (EAP): Data from Patients with Advanced Non-Squamous NSCLC and Brain Metastases (ID 10056)
09:30 - 09:30 | Author(s): Francesco Grossi
- Abstract
Background:
Among patients (pts) affected by non-squamous non-small cell lung cancer (non-Sq-NSCLC), those with secondary brain metastases are very common and are characterized by a poor prognosis. As they are usually excluded from clinical trials, the EAP offered an opportunity to evaluate nivolumab efficacy and safety in these patients outside of a controlled clinical trial in Italy.
Method:
Nivolumab was available upon physician request for pts aged ≥18 years with a diagnosis of non-Sq-NSCLC who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV non-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 using Common Terminology Criteria for Adverse Events. Pts with brain metastasis were eligible if asymptomatic, neurologically stable and either off corticosteroids or on a stable dose or decreasing dose of ≤ 10 mg daily prednisone.
Result:
Out of 1588 patients with non-Sq-NSCLC participating in the EAP in Italy, 409 (26%) had asymptomatic and controlled secondary brain metastases. Pts received a median number of 7 doses (1-45) and had a median follow-up of 6.1 months (0.1-21.9). The disease control rate was 40%, including 3 pts with a complete response, 65 pts with a partial response and 96 with stable disease. Among these pts, 118 were receiving steroid therapy at baseline and 74 received concomitant radiotherapy. As of March 2017, median overall survival of this subpopulation was 8.1 months (6.2-10.1). Overall, among pts with brain metastasis, 337 discontinued treatment for any reason, with only 23 (7%) pts who discontinued treatment due to adverse events, in line with what observed in the general population and in previous studies.
Conclusion:
These data confirmed the activity of nivolumab in patients with non-Sq-NSCLC and brain metastases, supporting the use of nivolumab in this population with poor prognosis. Moreover, as already observed in other tumor types, safety results were consistent to what already reported and confirmed the favorable safety profile.

P1.01-065 - Treatment Beyond Progression with Nivolumab in Patients with Advanced Non-Squamous NSCLC: Results from the Italian Expanded Access Program (ID 9333)
09:30 - 09:30 | Author(s): Francesco Grossi
- Abstract
Background:
Because of the novel mechanism of action of immunotherapies like nivolumab, response patterns may differ from other therapies and may provide a rationale for considering treatment beyond progression. Immunotherapy protocols generally allow patients (pts) to continue treatment beyond investigator-assessed progressive disease (PD) as long as there is ongoing clinical benefit. Here we report the analysis of pts treated beyond PD in the Italian nivolumab EAP for pts with non-squamous non small cell lung cancer (Non-Sq-NSCLC).
Method:
Nivolumab was provided upon physicians’ request for pts aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV non-Sq-NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks for <24 months. Pts included in the analysis received ≥1 dose of nivolumab and were monitored for adverse events (AEs) 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.
Result:
In total, 1588 Italian pts with advanced Non-Sq-NSCLC received at least one dose of nivolumab in the EAP across 168 sites and 1056 (66%) had PD. Of those, 274 pts (26%) were treated beyond progression. Before being treated beyond PD, the disease control rates (DCR) was 28%, with 1 complete response (CR), 27 partial responses (PR) and 49 stable diseases (SD). Post PD, 58 of all pts treated beyond PD achieved a non-conventional benefit, meaning a subsequent tumor reduction or stabilization in tumor lesions. With a median follow-up of 10.3 months (0.1-21.9) and a median of 11 (4-44) doses, median overall survival for pts treated beyond PD was 15.5 months (range: 13.1-17.9). Overall, among pts treated beyond PD, 200 discontinued treatment for any reason, with only 11 (5.5%) pts who discontinued treatment due to adverse events, suggesting no increased safety signals.
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 reductions 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 this treatment strategy.
