RESUMO
BACKGROUND: In an early-phase study involving patients with advanced non-small-cell lung cancer (NSCLC), the response rate was better with nivolumab plus ipilimumab than with nivolumab monotherapy, particularly among patients with tumors that expressed programmed death ligand 1 (PD-L1). Data are needed to assess the long-term benefit of nivolumab plus ipilimumab in patients with NSCLC. METHODS: In this open-label, phase 3 trial, we randomly assigned patients with stage IV or recurrent NSCLC and a PD-L1 expression level of 1% or more in a 1:1:1 ratio to receive nivolumab plus ipilimumab, nivolumab alone, or chemotherapy. The patients who had a PD-L1 expression level of less than 1% were randomly assigned in a 1:1:1 ratio to receive nivolumab plus ipilimumab, nivolumab plus chemotherapy, or chemotherapy alone. All the patients had received no previous chemotherapy. The primary end point reported here was overall survival with nivolumab plus ipilimumab as compared with chemotherapy in patients with a PD-L1 expression level of 1% or more. RESULTS: Among the patients with a PD-L1 expression level of 1% or more, the median duration of overall survival was 17.1 months (95% confidence interval [CI], 15.0 to 20.1) with nivolumab plus ipilimumab and 14.9 months (95% CI, 12.7 to 16.7) with chemotherapy (P = 0.007), with 2-year overall survival rates of 40.0% and 32.8%, respectively. The median duration of response was 23.2 months with nivolumab plus ipilimumab and 6.2 months with chemotherapy. The overall survival benefit was also observed in patients with a PD-L1 expression level of less than 1%, with a median duration of 17.2 months (95% CI, 12.8 to 22.0) with nivolumab plus ipilimumab and 12.2 months (95% CI, 9.2 to 14.3) with chemotherapy. Among all the patients in the trial, the median duration of overall survival was 17.1 months (95% CI, 15.2 to 19.9) with nivolumab plus ipilimumab and 13.9 months (95% CI, 12.2 to 15.1) with chemotherapy. The percentage of patients with grade 3 or 4 treatment-related adverse events in the overall population was 32.8% with nivolumab plus ipilimumab and 36.0% with chemotherapy. CONCLUSIONS: First-line treatment with nivolumab plus ipilimumab resulted in a longer duration of overall survival than did chemotherapy in patients with NSCLC, independent of the PD-L1 expression level. No new safety concerns emerged with longer follow-up. (Funded by Bristol-Myers Squibb and Ono Pharmaceutical; CheckMate 227 ClinicalTrials.gov number, NCT02477826.).

BACKGROUND: Immune-checkpoint inhibitors (ICIs) are standard treatments for metastatic non-small cell lung cancer (NSCLC). Patients with poor performance status (PS) are underrepresented in clinical trials. We evaluate the efficacy and safety of ICIs in a real-world setting. METHODS: We conducted a multi-institutional retrospective study to assess clinical outcomes of NSCLC treated with ICIs. We categorized pts within two groups (PS 0-1 vs 2) and assessed clinical outcomes and safety. RESULTS: Two hundred and sixty nine patients were included, 44 patients (16.4%) had baseline PS 2 and 223 patients (82.9%) PS 0-1. The overall response rate (ORR) was 30.4%, median PFS was 7.26 months (95% CI 5.1-9.4), and median OS was 15.18 months (95% CI 9.5-20.9). Patients with a PS 2 were most likely to received ICIs in the second or later line (84.1% vs 64.6%; p = 0.01), had baseline steroids (21.4% vs 8.2%; p 0.010), lower response rate (16.7% vs 34.5%; p 0.02) and clinical benefit (35.7% vs 71%; p 0.000) compared to PS 0-1 pts. Moreover, PS ≥ 2 patients had shorter PFS, median 2.2 months (95% CI 1.3-3.1) compared to 9.9 months (95% CI 6.7-13.1] and shorter OS, 3.3 months (95% CI 2.6-4.2) versus 24.1 months (95% CI 16.1-32.1), respectively. PS was significantly associated with PFS and OS in multivariate analysis. As it was expected, immunotherapy was well tolerated with a safety profile comparable to the previous published data. CONCLUSION: Based on these retrospective results, patients with poor baseline performance status seem to have poor clinical outcomes with ICIs in the real-world setting.
RESUMO
OBJECTIVE: This study describes the real-world characteristics, treatment sequencing, and outcomes among Hispanic patients with locally advanced/metastatic ALK-positive non-small-cell lung cancer (NSCLC) treated with crizotinib. METHODS: A retrospective patient review was conducted for several centers in Latin America. Clinicians identified ALK-positive NSCLC patients who received crizotinib and reported their clinical characteristics, treatments, and survival. Overall survival and progression-free survival (PFS) were described. A Random Forest Tree (RFT) model was constructed to predict brain progression. RESULTS: A total of 73 patients were included; median age at diagnosis was 58 years, 60.3% were female, and 93.2% had adenocarcinoma. Eighty-nine percent of patients were never smokers/former smokers, 71.1% had ≥2 sites of metastasis, and 20.5% had brain metastases at diagnosis. The median PFS on first-line crizotinib was 7.07 months (95% CI 3.77-12.37) and the overall response rate was 52%. Of those who discontinued crizotinib, 55.9% progressed in the central nervous system (CNS). The RFT model reached a sensitivity of 100% and a specificity of 88% for prediction of CNS progression. CONCLUSIONS: The overall response rate and the PFS observed in Hispanic patients with ALK-positive NSCLC treated with first-line crizotinib were similar to those in previous reports. An RFT model is helpful in predicting CNS progression and can help clinicians tailor treatments in a resource-limited practice.

BACKGROUND: Checkpoint inhibitor therapy has demonstrated overall survival benefit in multiple tumor types. Tumor mutational burden (TMB) is a predictive biomarker for response to immunotherapies. This study evaluated the efficacy of nivolumab+ipilimumab in multiple tumor types based on TMB status evaluated using either tumor tissue (tTMB) or circulating tumor DNA in the blood (bTMB). PATIENTS AND METHODS: Patients with metastatic or unresectable solid tumors with high (≥10 mutations per megabase) tTMB (tTMB-H) and/or bTMB (bTMB-H) who were refractory to standard therapies were randomized 2:1 to receive nivolumab+ipilimumab or nivolumab monotherapy in an open-label, phase 2 study (CheckMate 848; NCT03668119). tTMB and bTMB were determined by the Foundation Medicine FoundationOne® CDx test and bTMB Clinical Trial Assay, respectively. The dual primary endpoints were objective response rate (ORR) in patients with tTMB-H and/or bTMB-H tumors treated with nivolumab+ipilimumab. RESULTS: In total, 201 patients refractory to standard therapies were randomized: 135 had tTMB-H and 125 had bTMB-H; 82 patients had dual tTMB-H/bTMB-H. In patients with tTMB-H, ORR was 38.6% (95% CI 28.4% to 49.6%) with nivolumab+ipilimumab and 29.8% (95% CI 17.3% to 44.9%) with nivolumab monotherapy. In patients with bTMB-H, ORR was 22.5% (95% CI 13.9% to 33.2%) with nivolumab+ipilimumab and 15.6% (95% CI 6.5% to 29.5%) with nivolumab monotherapy. Early and durable responses to treatment with nivolumab+ipilimumab were seen in patients with tTMB-H or bTMB-H. The safety profile of nivolumab+ipilimumab was manageable, with no new safety signals. CONCLUSIONS: Patients with metastatic or unresectable solid tumors with TMB-H, as determined by tissue biopsy or by blood sample when tissue biopsy is unavailable, who have no other treatment options, may benefit from nivolumab+ipilimumab. TRIAL REGISTRATION NUMBER: NCT03668119.

INTRODUCTION: The LIPI, based on pretreatment derived neutrophils/[leukocytes-neutrophils] ratio (dNLR) and LDH, is associated with immune checkpoint inhibitors (ICI) outcomes in advanced non-small-cell lung cancer (NSCLC). We aimed to assess baseline LIPI correlation with durvalumab consolidation outcomes in the locally advanced setting. MATERIAL AND METHODS: Multicentre retrospective study (330 patients) with stage III unresectable NSCLC treated with durvalumab after chemo-radiotherapy between April 2015 and December 2020; 65 patients treated with chemo-radiotherapy only. Baseline LIPI characterized 3 groups: good (dNLR≤3+LDH≤ULN), intermediate (dNLR>3/LDH>ULN) and poor (dNLR>3+LDH>ULN). Primary endpoint was overall survival (OS). RESULTS: In the durvalumab cohort, median age was 67 years, 95% smokers, 98% with a performance status of 0-1; 60% had nonsquamous histology and 16% a PD-L1 expression <1%. Radiotherapy was delivered concurrently in 81%. LIPI was evaluable in 216 patients: 66% good, 31% intermediate, 3% poor. LIPI significantly correlated with median OS (median follow-up: 19 months): 18.1 months vs. 47.0 months vs. not reached in poor, intermediate and good LIPI groups, respectively (P = .03). A trend between objective response rate and LIPI groups was observed: 0% vs. 41% vs. 45%, respectively (P = .05). The pooled intermediate/poor LIPI group was associated with shorter OS (HR 1.97; P = .03) and higher risk of progressive disease (OR 2.68; P = .047). Survivals and response were not influenced in the control cohort. CONCLUSION: Baseline LIPI correlated with outcomes in patients with locally advanced NSCLC treated with durvalumab consolidation, but not in those who only received chemo-radiotherapy, providing further evidence of its prognostic and potential predictive role of ICI benefit in NSCLC.

PURPOSE: We present 5-year results from CheckMate 227 Part 1, in which nivolumab plus ipilimumab improved overall survival (OS) versus chemotherapy in patients with metastatic non-small-cell lung cancer, regardless of tumor programmed death ligand 1 (PD-L1) status. METHODS: Adults with stage IV/recurrent non-small-cell lung cancer without EGFR mutations or ALK alterations and with tumor PD-L1 ≥ 1% or < 1% (n = 1739) were randomly assigned. Patients with tumor PD-L1 ≥ 1% were randomly assigned to first-line nivolumab plus ipilimumab, nivolumab alone, or chemotherapy. Patients with tumor PD-L1 < 1% were randomly assigned to nivolumab plus ipilimumab, nivolumab plus chemotherapy, or chemotherapy. End points included exploratory 5-year results for efficacy, safety, and quality of life. RESULTS: At a minimum follow-up of 61.3 months, 5-year OS rates were 24% versus 14% for nivolumab plus ipilimumab versus chemotherapy (PD-L1 ≥ 1%) and 19% versus 7% (PD-L1 < 1%). The median duration of response was 24.5 versus 6.7 months (PD-L1 ≥ 1%) and 19.4 versus 4.8 months (PD-L1 < 1%). Among patients surviving 5 years, 66% (PD-L1 ≥ 1%) and 64% (PD-L1 < 1%) were off nivolumab plus ipilimumab without initiating subsequent systemic anticancer treatment by the 5-year time point. Survival benefit continued after nivolumab plus ipilimumab discontinuation because of treatment-related adverse events, with a 5-year OS rate of 39% (combined PD-L1 ≥ 1% and < 1% populations). Quality of life in 5-year survivors treated with nivolumab plus ipilimumab was similar to that in the general US population through the 5-year follow-up. No new safety signals were observed. CONCLUSION: With all patients off immunotherapy treatment for ≥ 3 years, nivolumab plus ipilimumab increased 5-year survivorship versus chemotherapy, including long-term, durable clinical benefit regardless of tumor PD-L1 expression. These data support nivolumab plus ipilimumab as an effective first-line treatment for patients with metastatic non-small-cell lung cancer.

INTRODUCTION: Durvalumab is the standard-of-care as consolidation therapy after chemo-radiotherapy in stage III unresectable non-small cell lung cancer (NSCLC); however, its activity across patients with NSCLC harbouring driver genomic alterations (dGA) is poorly characterised. MATERIAL AND METHODS: Multicentre retrospective study including patients with stage III unresectable NSCLC treated with durvalumab after chemo-radiotherapy between April 2015 and October 2020 at 26 centres in Europe and America. Clinical and biological data were collected; dGA included: EGFR/BRAF/KRAS mutations (m) and ALK/ROS1 rearrangements (r). We evaluated progression-free survival (PFS) and overall survival (OS) based on dGA. RESULTS: Out of 323 patients included, 43 patients had one dGA: KRASm (n = 26; 8 G12C), EGFRm (n = 8; 6 del19/ex21), BRAFm (n = 5; 4 V600E) and ALKr (n = 4). The median age was 66 years [39-84], gender ratio 1:1, with 98% performance status (PS) 0-1 and 19% non-smokers; 88% had adenocarcinoma. PD-L1 was positive in 85% (n = 4 missing). In the whole cohort, the median PFS was 17.5 months (mo.) (95% CI, 13.2-24.9) and median OS 47 mo (95%CI, 47-not reached [NR]). No statistically significant differences in terms of the median PFS were observed between patients with dGA vs. non-dGA: 14.9 mo (95% CI, 8.1-NR) vs. 18 mo. (95% CI, 13.4-28.3) (P = 1.0); however, when analysed separately: the median PFS was NR (11.3-NR) in the KRASm G12C vs. 8.1 mo (5.8-NR) in the EGFRm del19/ex21 vs. 7.8 mo (7.7-NR) in the BRAFm V600E/ALKr (P = 0.02). CONCLUSIONS: We observed limited activity of durvalumab consolidation in patients with stage III unresectable NSCLC with EGFR/BRAFm and ALKr but not for those harbouring KRASm. Larger prospective studies are needed to confirm these findings.

INTRODUCTION: In CheckMate 227, nivolumab plus ipilimumab prolonged overall survival (OS) versus chemotherapy in patients with tumor programmed death-ligand 1 (PD-L1) greater than or equal to 1% (primary end point) or less than 1% (prespecified descriptive analysis). We report results with minimum 4 years' follow-up. METHODS: Adults with previously untreated stage IV or recurrent NSCLC were randomized (1:1:1) to nivolumab plus ipilimumab, nivolumab, or chemotherapy (PD-L1 ≥1%); or to nivolumab plus ipilimumab, nivolumab plus chemotherapy, or chemotherapy (PD-L1 <1%). Efficacy included OS and other measures. Safety included timing and management of immune-mediated adverse events (AEs). A post hoc analysis evaluated efficacy in patients who discontinued nivolumab plus ipilimumab due to treatment-related AEs (TRAEs). RESULTS: After 54.8 months' median follow-up, OS remained longer with nivolumab plus ipilimumab versus chemotherapy in patients with PD-L1 greater than or equal to 1% (hazard ratio = 0.76; 95% confidence interval: 0.65-0.90) and PD-L1 less than 1% (0.64; 0.51-0.81); 4-year OS rate with nivolumab plus ipilimumab versus chemotherapy was 29% versus 18% (PD-L1 ≥1%); and 24% versus 10% (PD-L1 <1%). Benefits were observed in both squamous and nonsquamous histologies. In a descriptive analysis, efficacy was improved with nivolumab plus ipilimumab relative to nivolumab (PD-L1 ≥1%) and nivolumab plus chemotherapy (PD-L1 <1%). Safety was consistent with previous reports. The most common immune-mediated AE with nivolumab plus ipilimumab, nivolumab, and nivolumab plus chemotherapy was rash; most immune-mediated AEs (except endocrine events) occurred within 6 months from start of treatment and resolved within 3 months after, mainly with systemic corticosteroids. Patients who discontinued nivolumab plus ipilimumab due to TRAEs had long-term OS benefits, as seen in the all randomized population. CONCLUSIONS: At more than 4 years' minimum follow-up, with all patients off immunotherapy treatment for at least 2 years, first-line nivolumab plus ipilimumab continued to demonstrate durable long-term efficacy in patients with advanced NSCLC. No new safety signals were identified. Immune-mediated AEs occurred early and resolved quickly with guideline-based management. Discontinuation of nivolumab plus ipilimumab due to TRAEs did not have a negative impact on the long-term benefits seen in all randomized patients.

BACKGROUND: Nivolumab was the first anti-programmed cell death 1 drug approved in Argentina for non-small-cell lung cancer treatment in the second-line setting. MATERIALS AND METHODS: The present study was a multicenter, observational, retrospective study of patients with progression to stage IV NSCLC during platinum-based chemotherapy who had received nivolumab monotherapy in a drug-expanded access program in Argentina. RESULTS: The data from 109 patients were assessed retrospectively for safety and clinical outcomes. The follow-up period was 8.83 months (interquartile range, 3.4-12.67); 57.8% were men, 29.4% were current smokers, and 78.0% had a diagnosis of nonsquamous cell cancer. The median number of chemotherapy lines before nivolumab was 2 (range, 1-4). Also, 59.6% had received radiotherapy and 89% had received platinum-based chemotherapy. The drug-related toxicity rate was 78.9%, the grade 2-3 toxicity rate was 28.4%, and 33.9% of patients had required corticosteroids. The treatment response was evaluated in 104 patients. The best response was a complete response in 2 (2%), partial response in 28 (27%), stable disease in 33 (32%), and progressive disease in 41 (39%). Univariate analysis revealed that the absence of corticosteroid use (P = .034), toxicity grade 1-3 (P = .0025), and performance status of ≤ 1 (P = .049) were associated with longer disease-free survival, performance status of ≤ 1 (P < .001), and toxicity grade 1-3 (P = .001) were associated with longer overall survival. On multivariate Cox regression analysis, toxicity grade 1-3 (hazard ratio [HR], 0.44; 95% confidence interval [CI], 0.24-0.81; P = .008) and age ≤ 50 years (HR, 0.28; 95% CI, 0.13-0.61; P = .001) were associated with longer progression-free survival and corticosteroid use was associated with shorter progression-free survival (HR, 2.06; 95% CI, 1.22-3.48; P = .007). CONCLUSIONS: The use of nivolumab in the real world setting in patients with heavily pretreated NSCLC was well tolerated and showed promising clinical efficacy. The performance status, use of corticosteroids, and immune-mediated toxicity seem to be the conditions that can affect the clinical outcomes.

BACKGROUND: To compare survival outcomes of patients with advanced or metastatic non-small cell lung cancer (NSCLC) who received immunotherapy as first-, second- or beyond line, versus matched patients receiving standard chemotherapy with special characterization of hyperprogressors. METHODS: A retrospective cohort study of 296 patients with unresectable/metastatic NSCLC treated with either, first-, second-, third- or fourth-line of immunotherapy was conducted. A matched comparison with a historical cohort of first-line chemotherapy and a random forest tree analysis to characterize hyperprogressors was conducted. RESULTS: Median age was 64 years (range 34-90), 40.2% of patients were female. A total of 91.2% of patients had an Eastern Cooperative Oncology Group (ECOG) performance score ≤ 1. Immunotherapy as first-line was given to 39 patients (13.7%), second-line to 140 (48.8%), and as third-line and beyond to 108 (37.6%). Median overall survival was 12.7 months (95% CI 9.67-14 months) and progression-free survival (PFS) of 4.27 months (95% CI 3.97-5.0). Factors associated with increased survival included treatment with immunotherapy as first-line (P < 0.001), type of response (P < 0.001) and PD-L1 status (P = 0.0039). Compared with the historical cohort, immunotherapy proved to be superior in terms of OS (P = 0.05) but not PFS (P = 0.2). A total of 44 hyperprogressors were documented (19.8%, [95% CI 14.5-25.1%]). Leukocyte count over 5.300 cells/dL was present in both hyperprogressors and long-term responders. CONCLUSIONS: Patients who receive immune-checkpoint inhibitors as part of their treatment for NSCLC have better overall survival (OS) compared with matched patients treated with standard chemotherapy, regardless of the line of treatment.
