MA 10.06 - Real-World Results in Non-Squamous Non-Small Cell Lung Cancer Patients: Italian Nivolumab Expanded Access Programme (ID 9580)
11:00 - 12:30 | Author(s): G. Tonini
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.
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.
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.
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.

P1.01-053 - Italian Nivolumab Expanded Access Programme (EAP): Data from Patients with Advanced Non-Squamous NSCLC and Brain Metastases (ID 10056)
09:30 - 16:00 | Author(s): G. Tonini
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.
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.
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.
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.
