Comparative Efficacy and Safety of Anti-PD-1/PD-L1 Immune Checkpoint Inhibitors for Refractory or Relapsed Advanced Non-Small-Cell Lung Cancer-A Systematic Review and Network Meta-Analysis.

ABSTRACT: The efficacy and safety of immune checkpoint inhibitors (ICIs) in refractory or relapsed advanced non-small-cell lung cancer (NSCLC) have not yet been compared with those of ramucirumab (Ram) plus docetaxel (Doc). Furthermore, comprehensive comparisons between ICIs have not been conducted to date. In the current study, a Bayesian network meta-analysis of related phase III clinical trials was performed to compare the efficacy and safety of Ram+Doc, Niv, Atz, and Doc treatments in patient groups lacking the PD-L1 constraint. Surface under the cumulative ranking area (SUCRA) revealed that the overall survival (OS) of patients treated with Niv was the highest, followed by Atz, Ram+Doc, and Doc. Regarding grades 3-5 treatment-related adverse events (G3-5AEs), the use of Niv was ranked the safest, followed by Atz, Doc, and Ram+Doc. Significant differences in OS were observed between Niv and Ram+Doc, while significant differences in G3-5AEs were observed between Ram+Doc and Niv or Atz. In the PD-L1 positive (?1%) patient subgroup, Pem (10 mg/kg) ranked the highest in efficacy for OS, followed by Niv, Pem (2 mg/kg), Atz, and Doc. These findings may expectedly provide oncologists with useful insights into therapeutic selection for refractory or relapsed advanced NSCLC.

Project description:Immune checkpoint inhibitors (ICIs) are recommended as first-line treatment for late-stage non-small cell lung cancer (NSCLC), either as monotherapy or in combination with chemotherapy. However, efficacy and safety comparisons between ICIs as monotherapy and ICIs with chemotherapy are lacking. We searched PubMed, Embase, and Cochrane Library for randomized controlled trials published before February 29th, 2020, with the search terms "immunotherapy" and "chemotherapy". 10 eligible trials were identified with a total of 5,956 patients. Of these patients, 3,204 received immune therapy and 2,752 received chemotherapy. PD-1 inhibitors with chemotherapy improved OS (HR 0.84, 0.77-0.92), PFS (HR 0.80, 0.75-0.85), and objective response rate (ORR) (odds ratio (OR) 2.55, 1.20-5.28) compared to PD-1 inhibitors as monotherapy. In contrast, PD-L1 inhibitors plus chemotherapy showed no significant differences in OS, PFS, or ORR compared with PD-L1 inhibitors as monotherapy. When patients were stratified according to PD-L1 expression level, patients with high PD-L1 expression (≥ 50%) receiving PD-1 inhibitors plus chemotherapy had improved PFS, but not other outcomes, compared to PD-1 inhibitors as monotherapy. In these patients, PD-L1 inhibitors plus chemotherapy showed no significant difference in survival compared with PD-L1 inhibitors. In the low PD-L1 expression group (1%-49%), PD-1 inhibitors plus chemotherapy improved OS and PFS, but no advantage was observed in PD-L1 inhibitors plus chemotherapy in OS, PFS, or ORR compared with PD-L1 inhibitor monotherapy. When comparing PD-1/PD-L1 inhibitors plus chemotherapy with PD-1/PD-L1 inhibitors monotherapy, no significant differences were observed in the rate of immune-related adverse events (AEs). In summary, for treating patients with late-stage NSCLC, PD-1 inhibitors plus chemotherapy have improved efficacy compared with PD-1 inhibitor monotherapy, but PD-L1 inhibitors plus chemotherapy have similar efficacy as PD-L1 monotherapy. Survival benefits of PD-1/PD-L1 inhibitors combined with chemotherapy were particularly significant in patients with low PD-L1 expression levels.Systematic review registrationPROSPERO, identifier CRD42020166678 (https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=166678).
