Comparative safety and efficacy of immune checkpoint inhibitors after failure of chemotherapy in non-small cell lung cancer
Summary:
Introduction
Both pembrolizumab and nivolumab have been established as valid options in second and further-line treatment of non-small cell lung cancer, despite the lack of direct comparison in a randomized clinical trial. The aim of this study was to examine possible differences of efficacy and safety between pembrolizumab and nivolumab in this group of patients.
Methods
Patients with non-small cell lung cancer receiving second and further-line immunotherapy with either pembrolizumab or nivolumab in our hospital from 01/2017 – 01/2020 were retrospectively analysed. We collected data on demographics, overall response rate (ORR), progression-free survival (PFS), duration of response (DOR) and immune-related toxicity. Analysis included comparison of the two immunotherapeutics and determination of factors associated with prognosis.
Results
Sample consisted of 196 patients with a mean age of 66.6 years. 46 patients (23.5%) were treated with pembrolizumab and 150 (76.5%) with nivolumab. Baseline characteristics were similar (p>0.05), except for PD-L1 expression, which was higher in the pembrolizumab group (p<0.001). There were no differences regarding ORR and DCR (18.2 vs. 22.6% and 54.3 vs. 49.4% respectively, p=0.252), PFS (5.0 vs. 4.0 months, p=0.520), DOR (not estimated vs. 11.0 months, p=0.662) and immune-related toxicity (34.8 vs. 31.3%, p=0.549) between the two
groups. Multivariate analysis revealed immune-relate toxicity (HR 0.35, 95% CI 0.23 ─ 0.52, p<0.001) and performance status ≥ 2 (HR 1.86, 95% CI 1.30 ─ 2.65, p<0.001) as the only predictive factors for disease progression. Immune-related toxicity was associated with longer DOR as well (HR 0.44, 95% CI 0.25 ─ 0.79).
Conclusions
Our findings support that pembrolizumab and nivolumab present similar efficacy and safety in second and further-line setting. Immune-related toxicity and performance status are factors independently affecting prognosis.
