Nivolumab plus ipilimumab versus carboplatin-based doublet as first-line treatment for patients with advanced non-small-cell lung cancer aged ≥70 years or with an ECOG performance status of 2 (GFPC 08-2015 ENERGY): a randomised, open-label, phase 3 study.
Combined treatment with anti-PD-1 and anti-CTLA-4 antibodies has shown superiority over chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC), but data for older patients (aged ≥70 years) with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 or those with an ECOG performance status of 2 are scarce. We aimed to test the superiority of the PD-1 antibody nivolumab and the CTLA-4 antibody ipilimumab over platinum-based doublet chemotherapy as first-line treatment in patients with NSCLC aged 70 years or older or with an ECOG performance status of 2.
This open-label, multicentre, randomised, controlled, phase 3 trial was done at 30 hospitals and cancer centres in France. Eligible patients had stage IV histologically proven NSCLC, with no known oncogenic alterations, and were either aged 70 years or older with ECOG performance status of 0-2 or younger than 70 years with an ECOG performance status of 2. Patients were randomly assigned (1:1) centrally, using a computer-generated algorithm stratified by age (<70 vs ≥70 years), ECOG performance status (0-1 vs 2), and histology (squamous vs non-squamous) to receive nivolumab plus ipilimumab or platinum-based doublet chemotherapy (carboplatin [area under the curve ≤700 mg] plus pemetrexed [500 mg/m2 intravenous infusion every 3 weeks] or carboplatin [on day 1; area under the curve ≤700 mg] plus paclitaxel [90 mg/m2 as intravenous infusion on days 1, 5, and 15, every 4 weeks]). The primary endpoint was overall survival; secondary endpoints included progression-free survival and safety. All efficacy analyses were performed in the intention-to-treat population, which included all randomly assigned patients. Safety was analysed in the safety analysis set, which included all randomly assigned patients who received at least one dose of study treatment and who had at least one safety follow-up. The trial is registered with ClinicalTrials.gov, NCT03351361.
The trial was stopped early for futility on the basis of a pre-planned interim analysis after 33% of the expected events had occurred. Between Feb 12, 2018, and Dec 15, 2020, 217 patients were randomly assigned, of whom 216 patients were included in the final analysis, with 109 patients in the nivolumab plus ipilimumab group and 107 in the chemotherapy group; median age was 74 years (IQR 70-78). Median overall survival was 14·7 months (95% CI 8·0-19·7) in the nivolumab plus ipilimumab group and 9·9 months (7·7-12·3) in chemotherapy group (hazard ratio [HR] 0·85 [95% CI 0·62-1·16]). Among patients aged 70 years or older with an ECOG performance status of 0-1 (median age 76 years [IQR 73-79]), median overall survival was longer in the nivolumab plus ipilimumab group than the chemotherapy group: 22·6 months (95% CI 18·1-36·0) versus 11·8 months (8·9-20·5; HR 0·64 [95% CI 0·46-0·96]). Among patients with an ECOG performance status of 2 (median age 69 years [IQR 63-75]), median overall survival was 2·9 months (95% CI 1·4-4·8) in the nivolumab plus ipilimumab group versus 6·1 months (3·5-10·4) in the chemotherapy group (HR 1·32 [95% CI 0·82-2·11]). No new safety signals were reported. The most frequent grade 3 or worse adverse events were neutropenia (28 [27%] of 103 patients) in the chemotherapy group and endocrine disorders (five [5%] of 105 patients), cardiac disorders (ten [10%] patients), and gastrointestinal disorders (11 [11%] patients) in the nivolumab plus ipilimumab group.
The study showed no benefit of nivolumab plus ipilimumab combination in the overall study population. As a result of early stopping, the trial was underpowered for primary and secondary endpoints; however, the finding of better survival with nivolumab plus ipilimumab compared with platinum doublet in the subgroup of older patients with NSCLC with an ECOG performance status of 0-1 warrants further study.

Comparison of efficacy and safety of PD-1/PD-L1 combination therapy in first-line treatment of advanced NSCLC: an updated systematic review and network meta-analysis.
The use of immune checkpoint inhibitors has led to an increase in randomized controlled trials exploring various first-line combination treatment regimens. With the introduction of new PD-1/PD-L1 inhibitors, there are now more clinical options available. For the first time, the AK105 monoclonal antibody Penpulimab, developed in China, was included. The AK105-302 Phase III trial studied the efficacy and safety of Penpulimab combined with chemotherapy in patients with advanced or metastatic squamous NSCLC. To determine the optimal treatment options, we conducted an updated network meta-analysis to compare the effectiveness and safety of these regimens.
The system retrieves data from Chinese and English electronic databases, Clinical Trials, and the gov Clinical Trial Registration website up to September 6, 2023. The study indirectly compared the efficacy and safety of PD-1/PD-L1 combination regimens, including overall survival (OS), progression-free survival (PFS), objective response rate (ORR), all-grade adverse events, and above-grade III adverse events. Subgroup analyses were conducted based on programmed death ligand 1 (PD-L1) level, histological type, ECOG score, sex, and smoking history.
Nineteen RCTS were included, with a total of ten thousand eight hundred patients. Penpulimab plus chemotherapy (Pen + CT) provided the best OS (HR = 0.55, 95% CI 0.38-0.81) for PD-L1 patients with non-selective advanced NSCLC. Except Nivolumab plus Ipilimumab (Niv + Ipi), other PD-1/PD-L1 combination therapies significantly extended PFS compared with CT, and Nivolumab plus Bevacizumab combined with chemotherapy (Niv + Bev + CT) (HR = 0.43, 95% CI 0.26-0.74) provided the best PFS benefit and was comparable to Pen + CT (HR = 1.0) for PFS prolongation. For ORR, except Niv + Ipi, all the other regimens significantly improved ORR compared with CT. In terms of safety, except Tor + CT, the incidence of any-grade AEs or grade ≥ 3 adverse events may be higher than those of chemotherapy. The subgroup analysis revealed that for patients with PD-L1 levels below 1%, treatment with Tor + CT resulted in the best progression-free survival (HR = 0.47, 95% CI 0.25-0.86). For patients with PD-L1 levels of 1% or higher, Sintilimab plus chemotherapy (Sin + CT) (HR = 0.56, 95% CI 0.31-0.99) and Camrelizumab plus chemotherapy (Cam + CT) (HR = 0.43, 95% CI 0.28-0.64) were associated with the best overall survival and progression-free survival, respectively. For patients with SqNSCLC, combined immunotherapy may provide greater survival benefits. For patients with Non-sqNSCLC, Niv + Bev + CT and Tor + CT were associated with optimal PFS and OS, respectively. Cam + CT provided the best PFS in male patients with a history of smoking and an ECOG score of 0. In both female and non-smoking patient subgroups, Pem + CT was associated with the best PFS and OS benefits.
For patients with advanced non-selective PD-L1 NSCLC, two effective regimens are Pen + CT and Niv + Bev + CT, which rank first in OS and PFS among all patients. Cam + CT and Tor + CT have advantages for OS in patients with SqNSCLC and Non-sqNSCLC, respectively. Niv + Ipi + CT provided the best OS benefit for patients with an ECOG score of 0, while Pem + CT may be the most effective treatment for patients with an ECOG score of 1. Pem + CT has a better effect on female patients and non-smokers. Sin + CT was found to be the most effective treatment for male patients and the smoking subgroup, while Cam + CT was found to be the most effective for PFS. In addition, Tor + CT was associated with the best PFS for patients with negative PD-L1 expression. Pem + CT was found to significantly improve both PFS and OS compared to CT alone. For patients with positive PD-L1 expression, Sin + CT and Cam + CT were found to be optimal for OS and PFS, respectively. It is important to note that, with the exception of Tor + CT, the toxicity of the other combinations was higher than that of CT alone.
