P1.01-058 - Real World Data with Nivolumab: Experience in Argentina (ID 8800)
09:30 - 09:30 | Author(s): Eduardo Richardet
- Abstract
Background:
Nivolumab has improved overall survival (OS) in metastatic non-small cell lung cancer (NSCLC) patients. Analysis of the use of these drugs in real world provides more evidence about efficacy and toxicity. We describe here the experience of the use of nivolumab in NSCLC in Argentina.
Method:
NSCLC patients (pts) who received nivolumab between 6/2015 - 12/2016. Patients consented their respective physicians to be treated on a drug expanded access program. Data was collected retrospectively by the physician. Images and follow up were done according to physician´s discretion. Adverse events were classified according to CTC3.1. Responses were evaluated according to RECIST 1.1 criteria. DFS and OS was assessed. All pts who received at least one dose of Nivolumab were evaluated for toxicity.
Result:
N 109. Fup 8.83 m (IQR 3.4-12.67). 57.8% men, 29.4% current smoker, 78.0% non-squamous, 8.3% EGFR mutated. Chemotherapy lines before nivolumab 2 md (r 1-4), and 59.6% received radiotherapy. 89% received previously platinum based chemotherapy. Sites of relapse or progression before nivolumab were: lung (75.2%), lymph nodes (47.7%), bone (19.3%), liver (11.9%), central nervous system (11.0%), and adrenal gland (13.8%). PS 0 26.6%, 1 56.0%, 2 13.8% and 3 1.8%. Cycles of nivolumab 10 Md (IQR 3-18). Drug related toxicity 78.9%. Grade 2-3 28.4%. Corticoid use 33.9%. Responses were evaluated in 104 pts who had as best response CR 2/104 (2%), PR 28/104 (27. %), SD 33/104 (32%) and PD 41/104 (39.%). Time to the best response was 4.0 m (IQR 2.3-5.9). DFS 6.1 m (IQR 2.4-13.1) and OS 12.3 m (IQR 4.1-NR). Univariate analysis revealed that absence of corticoids use (p=0.034), toxicity grade 1-3 (p=0.0025), PS≤1 (p=0.049), age<=50 (p= 0.0011) were associated with longer DFS; PS≤1 (p<0.001) and toxicity grade 1-3 (p=0.001) were associated with longer OS. In multivariate cox regression analysis, toxicity grade 1-3 (HR 0.44 CI95% 0.24-0.81, p=0.008) and age<=50 (HR 0.28 CI95% 0.13-0.61, p=0.001) were associated with longer DFS while corticoids use was associated with shorter DFS (HR 2.06 CI95% 1.22-3.48, p=0.007); toxicity grade 1-3 (HR 0.28 CI95% 0.14-0.54, p<0.0001) and PS≤1 (HR 0.16 CI95% 0.08-0.31, p<0.0001) were associated with longer OS.
Conclusion:
The use of Nivolumab in a real world setting, in heavily pre-treated NSCLC patients was well tolerated and showed promising clinical efficacy. PS, the use of corticoids and immune-mediated toxicity seem to be conditions which could affect clinical outcomes.
