Real-World Experience of Nivolumab in Non-small Cell Lung Cancer in Korea.

ABSTRACT: PURPOSE:The introduction of immune checkpoint inhibitors represents a major advance in the treatment of lung cancer, allowing sustained recovery in a significant proportion of patients. Nivolumab is a monoclonal anti-programmed death cell protein 1 antibody licensed for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) after prior chemotherapy. In this study, we describe the demographic and clinical outcomes of patients with advanced NSCLC treated with nivolumab in the Korean expanded access program. Materials and Methods:Previously treated patients with advanced nonsquamous and squamous NSCLC patients received nivolumab at 3 mg/kg every 2 weeks up to 36 months. Efficacy data including investigator-assessed tumor response, progression data, survival, and safety data were collected. RESULTS:Two hundred ninety-nine patients were treated across 36 Korean centers. The objective response rate and disease control rate were 18% and 49%, respectively; the median progression-free survival was 2.1 months (95% confidence interval [CI], 1.87 to 3.45), and the overall survival (OS) was 13.2 months (95% CI, 10.6 to 18.9). Patients with smoking history and patients who experienced immune-related adverse events showed a prolonged OS. Cox regression analysis identified smoking history, presence of immune-related adverse events as positive factors associated with OS, while liver metastasis was a negative factor associated with OS. The safety profile was generally comparable to previously reported data. CONCLUSION:This real-world analysis supports the use of nivolumab for pretreated NSCLC patients, including those with an older age.

Project description:Postmarketing surveillance of Japanese patients with unresectable, previously treated, advanced or recurrent non-small-cell lung cancer treated with nivolumab was undertaken during the conditional approval period. The study aim was to evaluate the occurrence of treatment-related adverse events of nivolumab in the real world. Patients were registered between December 2015 and March 2016 at 536 sites. Nivolumab was given intravenously (3 mg/kg every 2 weeks); the observation period was 12 months after the first dose of nivolumab. Patients were evaluated for safety (n = 3601; 18.2% ≥75 years, 22.4% ECOG performance status ≥2) and effectiveness (n = 3570). The frequencies of any grade and grade 3 or higher treatment-related adverse events were 47.1% and 15.9%, respectively. The most frequent treatment-related adverse events (any grade) were interstitial lung disease (6.4%), hypothyroidism (5.7%), and diarrhea (4.4%). Treatment-related adverse events of special interest (priority items) occurring at a frequency of 5% or more were adverse events related to interstitial lung disease, thyroid dysfunction, liver dysfunction, colitis/severe diarrhea, infusion reaction, and infusion reaction within 24 hours. Significant risk factors for these priority items were identified by competing risk analysis: interstitial lung disease (previous/comorbid interstitial lung disease, abnormal findings on chest imaging, and smoking history); liver dysfunction (previous/comorbid liver disease, smoking history, and metastasis); thyroid dysfunction (previous/comorbid thyroid disease and performance status); and colitis/severe diarrhea (treatment line 2 vs ≥3). The 12-month survival rate was 40.7%. In conclusion, the safety profile of nivolumab in this postmarketing surveillance was similar to that in clinical trials, and no new safety signals were identified. The study was registered with the Japan Pharmaceutical Information Center (clinicaltrials.jp: Japic-163271).

Project description:ObjectivesWe aimed to examine clinical data and baseline blood test results as potential predictive biomarkers for benefit from nivolumab, in advanced non-small cell lung cancer patients (NSCLC).Materials and methodsA chart review was performed of 108 advanced NSCLC patients who commenced treatment with nivolumab between 2015-6 at three Israeli cancer centers, and for whom laboratory tests results were available. Data collected included sex, age, ECOG-PS, histology and number of previous lines of treatment. Baseline blood test results collected: absolute lymphocyte and neutrophil count (ANC), white blood cells (WBC), hemoglobin, platelets, albumin and lactate dehydrogenase (LDH). Neutrophil to Lymphocyte Ratio and 'derived NLR' (dNLR = (ANC/[WBC-ANC])) were calculated. Disease control at six months (DC6) was defined as any tumor shrinkage or stable disease during the first six months of nivolumab treatment. The association between clinical/laboratory variables and survival was tested with a Cox proportional hazard model. Data cut-off occurred in November 2019.Results35 patients (32.4%) achieved DC6. Median overall survival (OS) of entire study population was 5.4 months. Four year survival rate was 16%. Achievement of DC6 strongly correlated with longer OS (HR 0.12, 95% C.I. 0.07-0.21, p<0.001). In univariate and multivariate analysis, dNLR, albumin and LDH correlated significantly with OS. No variables correlated significantly with DC6 in multivariate analysis. Based on albumin and LDH, we produced a score called CLAS (combined LDH and albumin score), including four prognostic groups of patients. Patients having low albumin and high LDH had the worst prognosis.ConclusionIn real-life setting, long-term efficacy of nivolumab in advanced line treatment of NSCLC is consistent with clinical trials. Response or stability of disease during first six months of treatment is associated with prolonged survival. We propose a novel score (CLAS) that may be useful for predicting outcome in nivolumab-treated NSCLC patients, but further validation is required.

Project description:BackgroundTargeted agents have improved the outcome of a subset of non-small cell lung cancer (NSCLC). Molecular profiling by next-generation sequencing (NGS) allows screening for multiple genetic alterations both in tissue and in plasma, but limited data are available concerning its feasibility and impact in real-world clinical practice.MethodsPatients with advanced NSCLC consecutively referring to our Institution for potential eligibility to VISION trial (NCT02864992) were prospectively enrolled. They were already screened with standard method, and EGFR/ALK/ROS-1 positive cases were excluded. NGS was performed in plasma and tissue using the Guardant360 test covering 73 genes and the Oncomine Focus Assay covering 59 genes, respectively.ResultsThe study included 235 patients. NGS was performed in plasma in 209 (88.9%) cases; 78 of these (37.3%) were evaluated also in tissue; tissue only was analyzed in 26 cases (11.1%). Half of the tissue samples were deemed not evaluable. Druggable alterations were detected in 13 (25%) out of 52 evaluable samples and 31 of 209 (14.8%) of plasma samples. Improved outcome was observed for patients with druggable alterations if treated with matched targeted agents: they had a longer median overall survival (not reached) compared with the ones who did not start any targeted therapy (9.1 months; 95% confidence interval, 4.6-13.6; p = .046). The results of NGS testing potentially also affected the outcome of patients treated with immunotherapy.ConclusionSystematic real-life NGS testing showed the limit of tissue analysis in NSCLC and highlighted the potentiality of genetic characterization in plasma in increasing the number of patients who may benefit from NGS screening, both influencing the clinical decision-making process and affecting treatment outcome.Implications for practiceGenetic characterization of cancer has become more important with time, having had positive implications for treatment specificity and efficacy. Such analyses changed the natural history of advanced non-small cell lung cancer (aNSCLC) with the introduction of drugs targeted to specific gene alterations (e.g., EGFR mutations, ALK and ROS-1 rearrangements). In the field of cancer molecular characterization, the applicability of the analysis of a wide panel of genes using a high-throughput sequencing approach, such as next-generation sequencing (NGS), is still a matter of research. This study used NGS in a real-world setting to systematically and prospectively profile patients with aNSCLC. The aim was to evaluate its feasibility and reliability, as well as consequent access to targeted agents and impact on clinical outcome whenever a druggable alteration was detected either in tumor tissue samples or through liquid biopsy.
