Background:
Nivolumab is a standard option for second‐line treatment in pts with advanced NSCLC. Real‐life data are lacking regarding the efficacy of nivolumab and post‐nivolumab treatment.
Method:
This analysis included the first 600 consecutive pts with stage IIIB/IV NSCLC who received ≥1 dose of nivolumab 3mg/kg q2w through the French EAP from 01/2015 for Squamous ﴾Sq﴿ and 06/2015 for Non‐Sq NSCLC, until 08/2015.
Result:
Median age was 64 yo, there were 409 ﴾68%﴿ men, 521 ﴾87%﴿ smokers, 478 ﴾80%﴿ PS0/1 pts, 230 ﴾38%﴿ Sq and 370 ﴾62%﴿ Non‐Sq NSCLC, 130 ﴾22%﴿ pts with brain metastases. Nivolumab was administered as 2nd/3rd/≥4th‐line for 26%/33%/41% pts, respectively. Best response was PR/SD/PD for 17%/30%/37% of patients, respectively, with 16% not assessable. Toxicities occurred in 187 ﴾31%﴿ pts, including 10% grade ≥3 events. After a median follow‐up of 22.1 ﴾95% CI 21.6‐22.6﴿ months, median PFS and OS from the initiation of nivolumab were 2.1 ﴾95%CI 1.9‐2.3﴿ and 9.5 ﴾95%CI 8.4‐10.8﴿ months, respectively. In the 92 pts with PS2 at initiation of nivolumab, PR/SD rates were 7%/28%; median OS was 3.6 (95%CI 2.7-5.2) months. A total of 130 pts had brain metastases at initiation of nivolumab: PR/SD rates were 12%/25%; median OS was 6.6 (95%CI 3.8-8.3) months. Post‐nivolumab treatment was administered to 262 ﴾44%﴿ pts, and mostly consisted of gemcitabine ﴾19%﴿, docetaxel ﴾18%﴿, paclitaxel ﴾14%﴿, erlotinib ﴾12%﴿, vinorelbine ﴾9%﴿, platin‐based doublet ﴾8%﴿, or pemetrexed ﴾8%﴿. Access to post‐nivolumab treatment was higher in PS0/1 vs. PS2 pts ﴾48% vs. 23%, p<0.001﴿, but was not different according to histology or treatment line or disease control with nivolumab. Best response to post‐nivolumab treatment was PR/SD/PD for 15%/42%/42% of pts, respectively. In the whole cohort, median post‐nivolumab OS was 4.0 ﴾95%CI 2.8‐4.6﴿ months, and was significantly higher in case of PR to nivolumab ﴾HR=0.38; 95%CI 0.23‐0.64; p<0.001﴿, and if subsequent treatment was delivered ﴾HR=0.30; 95%CI 0.24‐0.38; p<0.001﴿; median post‐nivolumab OS in pts receiving post‐nivolumab treatment was 7.5 ﴾95%CI 6.8‐8.7﴿ months, and did not differ based on histology or treatment line.
Conclusion:
Efficacy and safety of nivolumab was in line with available data. Post‐nivolumab treatment may be delivered in many pts, including pts with PS2 and brain metastases, with favorable impact on response and OS. Data on the whole cohort of 900 pts enrolled in the EAP will be presented.
