Non-Small-Cell Lung Cancer (NSCLC) Harboring ALK Translocations: Clinical Characteristics and Management in a Real-Life Setting: a French Retrospective Analysis (GFPC 02–14 Study)

Background

Chromosomal translocations involving the anaplastic lymphoma kinase gene (ALK) are rare oncogenic events found in 3–5% of non-small-cell lung cancers (NSCLC). Limited data have been published on the management of these patients outside clinical trials.

Objective

To investigate the clinical characteristics and management of patients with NSCLC harboring ALK translocations (ALK+) in a real-life setting in France.

Methods

This multicenter, observational, retrospective study included all NSCLC patients harboring ALK translocations diagnosed in participating centers between January 2012 and December 2014. Patient data include clinical characteristics, disease management, and outcomes [progression-free survival (PFS) and overall survival (OS)].

Results

The 31 participating centers reported data on 132 patients, of whom 51% (n = 67) were male. The median age was 60.1 ± 14.5 (standard deviation) years; 89% (n = 106/119) had performance status 0/1 at diagnosis; 79% (n = 103/130) were non- or former smokers; 93% (n = 120/129) had adenocarcinomas and 74%(n = 97)/19%(n = 25)/7%(n = 10) had disease stages IV/III/I-II at diagnosis, respectively; co-mutations included EGFR (n = 2), BRAF (n  = 2), KRAS (n = 1), and HER2 (n = 1). Of the patients with stage IV NSCLC (n = 97), 96% received first-line treatment [75% chemotherapy-based, 21% ALK tyrosine kinase inhibitor (TKI)], with an associated response rate (RR), disease-control rate (DCR), and PFS of 42%, 64%, and 7.5 [95% confidence interval (CI) 5.9–9.5] months, respectively; 62% received second-line treatment (28% chemotherapy, 72% ALK TKI) with an associated RR, DCR, and PFS of 43.4%, 70%, and 4.7 (95% CI 4.0–8.1) months, respectively. The 2-year OS was 56.7% (95% CI 45.5–70.4%); median OS was not reached.

Conclusion

The results of this real-life analysis suggest that the prognosis of NSCLC patients with theALK translocation may be better than that of the overall NSCLC population, but the outcomes were poorer than those of ALK+ NSCLC patients included in clinical studies.

Efficacy and Safety of Anti-PD-1 Immunotherapy in Patients Aged ≥ 75 Years With Non–small-cell Lung Cancer (NSCLC): An Italian,Multicenter, Retrospective Study

IntroductionNon–small-cell lung cancer (NSCLC) is predominantly a disease of the elderly population. Over the past few years, immunotherapy with monoclonal antibodies named checkpoint inhibitors (ICIs) greatly improved the clinical management of a significant proportion of patients with metastatic NSCLC. However, pivotal trials excluded older patients, although, given the favorable clinical profile of ICIs, this treatment may be revealed to be a most valuable option also for these patients. To this aim, a multicenter retrospective analysis was performed on patients aged ≥ 75 years with NSCLC treated with anti-programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) immunotherapy.Material and MethodsInclusion criteria were: diagnosis of locally advanced or metastatic NSCLC (stage IIIB or IV, according to the American Joint Committee on Cancer (AJCC) classification system, version 8.0); age ≥ 75 years; treatment with anti-PD-1/PD-L1 monoclonal antibodies in first or subsequent lines of treatment; absence of epidermal growth factor receptor-activating mutations or anaplastic lymphoma kinase and ROS-1 rearrangements. The primary endpoints of the study were the efficacy, in terms of overall response rate, progression-free survival, and overall survival, and safety, by means of evaluations of the incidence of immune-related adverse events.ResultsEighty-six patients were considered for the final analysis; 71 (82.6%) were male. The mean age was 78.5 years (range, 75-86 years; SD, 3.12 years). Of the 86 patients, 69 (80.2%) of patients had a performance status of 0 or 1. The overall median progression-free survival was 5.6 months (range 1-36 months; SD, 7.5 months,) whereas the median overall survival was 10.1 months (range, 1.7-34.8 months; SD, 8 months). At the Cox regression analysis, the only parameter significantly associated with survival was the smoking status (P = .008). No difference in survival was found between patients younger and older than 80 years.ConclusionsIn the present real-world retrospective cohort, efficacy and toxicity profiles of ICIs in older patients with advanced NSCLC were comparable with those observed in younger patients enrolled in clinical trials.     

Cost Analysis of Erlotinib Versus Chemotherapy for First-Line Treatment of Non–Small-Cell Lung Cancer in Frail Elderly Patients Participating in a Prospective Phase 2 Study (GFPC 0505)

BackgroundA large proportion of elderly patients (>70 years) with newly diagnosed NSCLC are shown to be frail by a comprehensive geriatric assessment. This population is more vulnerable to adverse effects of chemotherapy and might thus benefit more from targeted therapy. The objective of this study was to assess the cost-effectiveness of erlotinib followed by chemotherapy after progression, compared with the reverse strategy, in frail elderly patients with advanced NSCLC participating in a prospective randomized phase II trial (GFPC 0505).Materials and MethodsOutcomes (progression-free survival and overall survival) and costs (limited to direct medical costs, from the third-party payer perspective) were collected prospectively until second progression. Costs after progression and health utilities (based on disease states and grade 3-4 toxicities) were derived from the literature.ResultsMedian overall survival, QALYs, and total costs for the erlotinib-first strategy were 3.9 months, 0.33, and €15,233, respectively, compared with 4.4 months, 0.35, and €15,363 for the chemotherapy-first strategy. There was no significant difference between the 2 strategies in term of cost-effectiveness (respectively €47,381 and €44,350 per QALY).ConclusionNo difference in cost-effectiveness was found between an erlotinib-first strategy and a chemotherapy-first strategy in frail elderly patients with NSCLC.     

Clinical Implications of the T790M Mutation in Disease Characteristics and Treatment Response in Patients With Epidermal Growth Factor Receptor (EGFR)-Mutated Non–Small-Cell Lung Cancer (NSCLC)

Background

The secondary T790M mutation accounts for more than 50% of acquired tyrosine kinase inhibitor (TKI) resistance in patients with EGFR-mutated non–small-cell lung cancer (NSCLC). Recent reports suggest this resistance mutation may be more common among patients with longer progression-free survival (PFS) on first-line TKI therapy, but much is still unknown.

Ventana ALK (D5F3) in the Detection of Patients Affected by Anaplastic Lymphoma Kinase-positive Non–Small-cell Lung Cancer: Clinical and Budget Effect

Background

To ensure identification of anaplastic lymphoma kinase-positive (ALK⁺) patients, the Italian Drug Agency suggested a testing algorithm based on the use of fluorescence in situ hybridization (FISH) and/or immunohistochemistry. The aim was to evaluate the clinical and economic effects of adopting an immunohistochemical test (Ventana ALK D5F3) as an option for detecting ALK protein expression in advanced non–small cell lung cancer (NSCLC) patients.

Treatment Satisfaction of Patients With Advanced Non–Small-cell Lung Cancer Receiving Platinum-based Chemotherapy: Results From a Prospective Cohort Study (PERSONAL)

Introduction

In patients with advanced non–small-cell lung cancer, the treatment benefits and risks need to be constantly weighed. We explored patient-reported satisfaction with therapy (SWT) and assessed its value in addition to quality of life (QoL) and adverse events (AEs).

Predictive and Prognostic Potential of TP53 in Patients With Advanced Non–Small-Cell Lung Cancer Treated With EGFR-TKI: Analysis of a Phase III Randomized Clinical Trial (CTONG 0901)

BackgroundMutations in TP53 are commonly found in patients with epidermal growth factor receptor (EGFR) mutant advanced non–small-cell lung cancer (NSCLC). In this study, we determined the predictive and prognostic potential of different subtypes of TP53 using data from a phase III randomized trial (CTONG 0901).Patients and MethodsThe trial enrolled 195 patients who had undergone next-generation sequencing of 168 genes before treatment with EGFR tyrosine kinase inhibitors. Mutations in TP53 (exon 4 or 7, other mutations, and wild-type) were analyzed based on the therapeutic response and survival. A Cox proportional hazards model was used to determine the potential of the predictive and prognostic factors.ResultsAll 195 patients harbored activating EGFR mutations: the most common concomitant mutations were TP53 (134/195, 68.7%), CTNNB1 (20/195, 10.3%), and RB1 (16/195, 8.2%). The genetic profiles between patient subgroups administered first-line (132, 67.7%) or later-line (63, 32.3%) treatments did not significantly differ. The median progression-free survival in patients with mutations in exon 4 or 7 of TP53, other TP53 mutations, and wild-type TP53 were 9.4, 11.0, and 14.5 months (P = .009), respectively. Overall survival times were 15.8, 20.0, and 26.1 months (P = .004), respectively. Mutations in exon 4 or 7 of TP53 served as independent prognostic factors for progression-free (P = .001) and overall survival (P = .004) in patients.ConclusionMutations in exon 4 and/or 7 in TP53 are promising predictive and prognostic indicators in EGFR-mutated NSCLC.     

ASCEND-8: A Randomized Phase 1 Study of Ceritinib, 450 mg or 600 mg,Taken with a Low-Fat Meal versus 750 mg in Fasted State in Patients with Anaplastic Lymphoma Kinase (ALK)-Rearranged Metastatic Non–Small Cell Lung Cancer (NSCLC)

IntroductionCeritinib, 750 mg fasted, is approved for treatment of patients with ALK receptor tyrosine kinase gene (ALK)-rearranged (ALK-positive) NSCLC previously treated with crizotinib. Part 1 of the ASCEND-8 study determined whether administering ceritinib, 450 mg or 600 mg, with a low-fat meal may enhance gastrointestinal (GI) tolerability versus 750 mg fasted in patients with ALK-positive NSCLC while maintaining similar exposure.MethodsASCEND-8 is a multicenter, randomized, open-label, phase 1 study. Part 1 investigated the steady-state pharmacokinetics (PK) and safety of ceritinib, 450 mg or 600 mg, taken with a low-fat meal versus 750 mg fasted in patients with advanced ALK-positive NSCLC who were either treatment naive or pretreated with chemotherapy and/or crizotinib. Part 2 will assess efficacy and safety of ceritinib in treatment-naive patients.ResultsAs of June 16, 2016, 137 patients were randomized (450 mg fed [n = 44], 600 mg fed [n = 47], and 750 mg fasted [n = 46]); 135 patients received ceritinib. Median follow-up duration was 4.14 months. At steady state, relative to 750 mg fasted, 450 mg with food demonstrated comparable PK as assessed by maximum (peak) concentration of drug in plasma and area under the plasma concentration–time curve from time zero to 24 hours, whereas 600 mg with food demonstrated approximately 25% higher PK. Relative to 750 mg fasted, 450 mg with food was associated with a lower proportion of patients with GI toxicities, mostly grade 1 (diarrhea [43.2%], nausea [29.5%], and vomiting [18.2%]); there were no grade 3 or 4 events, study drug discontinuations, or serious AEs due to GI toxicities.ConclusionCeritinib, 450 mg with food, had similar exposure and a more favorable GI safety profile than ceritinib, 750 mg in fasted patients with ALK-positive NSCLC.     

Clinical Relevance of EGFR- or KRAS-mutated Subclones in Patients With Advanced Non–small-cell Lung Cancer Receiving Erlotinib in a French Prospective Cohort (IFCT ERMETIC2 Cohort - Part 2)

IntroductionEvaluation of EGFR Mutation status for the administration of EGFR-TKIs in non-small cell lung Carcinoma (ERMETIC) was a prospective study designed to validate the prognostic value of EGFR/KRAS mutations in patients with advanced non–small-cell lung cancer (NSCLC), all receiving a first-generation tyrosine kinase inhibitor, erlotinib. ERMETIC2 was an ancillary project evaluating the clinical value of common EGFR/KRAS-mutated subclones regarding prognosis using highly sensitive molecular detection methods.Materials and MethodsTumor samples from 228 patients with NSCLC (59% adenocarcinoma, 37% women, and 19% never/former smokers) were available for reanalysis using alternative highly sensitive molecular techniques. A multivariate Cox model was used for prognostic analysis.ResultsUsing alternative highly sensitive techniques, 16 EGFR and 51 KRAS supplementary mutations were newly identified, all still exclusive, leading to an overall rate of 12.3% (n = 28) and 33.3% (n = 76), respectively. Using real-time polymerase chain reaction (hybridization probe), they were significantly associated with progression-free survival (P = .02) and overall survival (OS) (P = .01), which were better for EGFR-mutated patients for progression-free survival (hazard ratio [HR], 0.46; 95% confidence interval [CI], 0.28-0.78) and OS (HR, 0.56; 95% CI, 0.31-1), and worse for KRAS mutations and OS (HR, 1.63; 95% CI, 1.09-2.44). Using the most sensitive technique detection for KRAS–clamp polymerase chain reaction–KRAS mutated subclones did not impact OS.ConclusionsKRAS and EGFR mutations were detected in higher proportions by alternative highly sensitive molecular techniques compared with direct Sanger sequencing. However, minor KRAS-mutated subclones offered no prognostic value when representing less than 1% of the tumor cells.     

Treatment Rationale and Design of a Phase III Study of Afatinib or Chemotherapy in Patients with Non–small-cell Lung Cancer Harboring Sensitizing Uncommon Epidermal Growth Factor Receptor Mutations (ACHILLES/TORG1834)

We describe the treatment rationale and design of our randomized phase III study, the ACHILLES trial (Japan Registry of Clinical Trials: jRCTs031180175). The aim of this study is to investigate the superiority of afatinib over chemotherapy as first-line treatment in patients with advanced nonsquamous non–small-cell lung cancer with sensitizing uncommon or compound epidermal growth factor receptor (EGFR) mutations, with the exception of de novo T790M mutations and exon 20 insertions. Eligible patients will be randomized at a 1:2 ratio to receive either chemotherapy or afatinib until disease progression or unacceptable toxicity. Patients in the chemotherapy arm will receive pemetrexed 500 mg/m² + cisplatin 75 mg/m² or carboplatin area under the curve (AUC) 5 or 6 every 3 weeks × 4 cycles, followed by pemetrexed 500 mg/m² every 3 weeks. In the afatinib arm, investigators will choose the starting dose of afatinib (30 mg or 40 mg orally daily). The primary endpoint is progression-free survival. A total of 106 patients will be enrolled in this trial over a 30-month registration period with a 15-month follow-up. Enrollment began in March 2019. The results of this trial will establish the superiority of afatinib over chemotherapy in a cohort with a large variety of EGFR mutations.     

Weekly Paclitaxel in Elderly Patients (Aged ≥ 70 Years) with Advanced Non–Small-Cell Lung Cancer: An Alternative Choice? Results of a Phase II Study

PURPOSE: Paclitaxel and platinum-based chemotherapy is considered to be a standard approach for locally advanced and metastatic non-small-cell lung cancer (NSCLC). In recent years, weekly paclitaxel has been widely used for its safety profile, especially in breast and ovarian cancer. Otherwise, only a few studies are available in NSCLC. The aim of our study was to investigate the activity and safety of weekly paclitaxel in elderly patients with locally advanced (stage IIIB) and metastatic (stage IV) NSCLC. PATIENTS AND METHODS: Twenty-seven patients entered the study; 10 had stage IIIB disease (5 "wet" and 5 "dry"), and 17 had stage IV disease. Median age was 73 years (range, 70-83 years). Sixteen patients (59%) presented with comorbidities. The schedule was weekly paclitaxel 80 mg/m2 for 6 weeks with 2 weeks of rest (1 cycle). RESULTS: All patients were evaluable for response and toxicity; a median of 1 cycle was administered (range, 1-5 cycles). Partial responses were recorded in 9 patients (37.5%; 33.3%, according to intention-to- treat analysis; 95% CI, 15.5%-51.1%); 7 had stable disease (29%), and 8 had progressive disease (33.5%). Median time to progression was 5 months (range, 1-23 months), and median survival was 12 months (range, 1-36 months). Grade 2/3 asthenia was the main toxicity in 7 patients (29%); a hypersensitivity reaction presented in 1 patient. No other episode of grade 3/4 toxicity was recorded. CONCLUSION: Our study confirmed that paclitaxel 80 mg/m2 weekly is active in patients with locally advanced and metastatic NSCLC with a good safety profile; this schedule might be considered an alternative choice to gemcitabine or vinorelbine as first-line treatment in elderly patients, particularly patients with comorbidities. Phase III studies that compare these third-generation drugs are warranted to draw definitive conclusion about the best approach in these patients.     

A Dose-finding Study Followed by a Phase II Randomized,Placebo-controlled Trial of Chemoradiotherapy With or Without Veliparib in Stage III Non–small-cell Lung Cancer: SWOG 1206 (8811)

BackgroundWe conducted a 2-part study to evaluate the incorporation of veliparib, a PARP inhibitor, into chemoradiotherapy (CRT) for stage III non–small-cell lung cancer.Patients and MethodsIn the phase I part, patients were treated successively at 3 dose levels of veliparib (40, 80, and 120 mg) twice daily during CRT. In the phase II part, patients were randomized to receive veliparib or placebo during thoracic radiotherapy with concurrent weekly carboplatin and paclitaxel, followed by 2 cycles of consolidation carboplatin and paclitaxel with veliparib or placebo. The study was prematurely discontinued owing to the emergence of adjuvant immunotherapy as standard of care.ResultsOf 21 patients enrolled in phase I, 2 patients developed dose-limiting toxicities (DLTs): 1 grade 3 esophagitis with dysphagia (at 40 mg) and 1 grade 3 esophagitis with dehydration (at 80 mg). No DLTs were seen at veliparib dose of 120 mg twice daily, which was selected for the phase II part that enrolled 31 eligible patients. Progression-free survival (PFS) was not different between the 2 arms (P = .20). For the veliparib and placebo arms, response rates were 56% and 69%, PFS at 1 year 47% and 46%, and overall survival at 1 year 89% and 54%, respectively.ConclusionVeliparib with CRT was feasible and well tolerated. Efficacy could not accurately be determined because of early study closure. Nonetheless, there is enthusiasm for the evaluation of PARP inhibitors in lung cancer as predictive biomarkers are being developed and combinations with immunotherapy are attractive.     

ROS1-rearranged Non–small-cell Lung Cancer is Associated With a High Rate of Venous Thromboembolism: Analysis From a Phase II,Prospective, Multicenter,Two-arms Trial (METROS)

BackgroundPatients with cancer are at increased risk for venous thromboembolism (VTE), and 8% to 15% of patients with advanced non–small-cell lung cancer (NSCLC) experience a VTE event during the course of their disease. The incidence of VTE in molecularly defined NSCLC subgroups is still unclear. In this study, we investigated the incidence and the clinical correlates of VTE in patients with ROS1-rearranged NSCLC enrolled in the METROS trial (NCT02499614).Patients and MethodsThe METROS trial is a prospective phase II study designed to assess efficacy, safety, and tolerability of crizotinib in patients with pre-treated metastatic NSCLC ROS1 rearrangement (cohort A) or with MET amplification or MET exon 14 mutation (cohort B). Patients with ROS1-rearranged NSCLC enrolled within cohort A and the expansion cohort of the trial were included in the primary analysis.ResultsAmong 48 patients with ROS1-rearranged NSCLC enrolled in the METROS study, 20 (41.6%) of 48 had at least 1 VTE event. Among them, 7 (35%) of 20 patients had ≥ 2 VTE events. VTE events consisted of pulmonary embolism (46.4%), deep vein thrombosis (39.2%), renal vein thrombosis (7.1%), internal jugular thrombosis (3.5%), and peripheral inserted central catheter-related thrombosis (3.5%). VTE events occurred at disease progression in 35.7% of cases, at diagnosis in 32.1% of cases, and during chemotherapy or crizotinib in 17.8% and 14.2%, respectively.ConclusionThe incidence of VTE is 3- to 5-fold higher in patients harboring ROS1-rearrangment than previously observed for the general population with NSCLC. Larger studies are warranted to confirm our findings and determine whether the molecular profile of NSCLC should be incorporated into a risk-stratification tool and decision-making algorithm for VTE diagnosis and prophylaxis.     

A Phase II Study of Regorafenib With a Lower Starting Dose in Patients With Metastatic Colorectal Cancer: Exposure–Toxicity Analysis of Unbound Regorafenib and Its Active Metabolites (RESET Trial)

BackgroundRegorafenib demonstrated survival benefits as salvage therapy for patients with metastatic colorectal cancer. However, severe toxicities frequently occurred early in the treatment with the standard dose (160 mg/day), resulting in a dose reduction or interruption. To improve the tolerability and maintain sufficient efficacy, we conducted a phase II study of regorafenib with a lower starting dose (120 mg/day).Patients and MethodsRegorafenib was initiated at 120 mg/day, and the dosage was increased to 160 mg/day on day 15 of the first cycle for patients who had met the dose escalation criteria. The primary endpoint was the disease control rate (DCR). The pharmacokinetics of the total and unbound regorafenib and its active metabolites (M2, M5) were assessed.ResultsA total of 70 patients were enrolled from September 2016 to December 2017. Only 6 patients achieved dose escalation to 160 mg on day 15 as planned. For the 68 evaluable patients, the DCR was 32.4% (95% confidence interval, 21.5%-44.8%), which was less than the threshold (30%) of our statistical hypothesis. The serum concentrations of total regorafenib for patients whose dose was escalated to 160 mg/day were significantly lower than those of the patients whose dose was not escalated (median, 3978 vs. 7244 nM; P = .027). The serum unbound concentrations of the sum of regorafenib and the active metabolites correlated significantly with the maximum grade of regorafenib-related symptomatic adverse events in the first cycle (11,138 vs. 19,096 pM; P = .035).ConclusionRegorafenib with a low starting dose of 120 mg/day did not achieve the expected DCR. A relationship of unbound exposure with toxicity was found.     

Temporal Profiles of Symptom Scores After Palliative Radiotherapy for Bleeding Gastric Cancer With Adjustment for the Palliative Prognostic Index: An Exploratory Analysis of a Multicentre Prospective Observational Study (JROSG 17–3)

AimsAlthough palliative radiotherapy for gastric cancer may improve some symptoms, it may also have a negative impact due to its toxicity. We investigated whether symptoms improved after radiotherapy with adjustment for the Palliative Prognostic Index (PPI) considering that patients with limited survival tend to experience deterioration of symptoms.Materials and methodsThis study was an exploratory analysis of the Japanese Radiation Oncology Study Group study (JROSG 17-3). We assessed six symptom scores (nausea, anorexia, fatigue, shortness of breath, pain at the irradiated area and distress) at registration and 2, 4 and 8 weeks thereafter. We tested whether symptoms linearly improved after adjusting for the baseline PPI. Shared parameter models were used to adjust for potential bias in missing data.ResultsThe present study analysed all 55 patients enrolled in JROSG 17-3. With time from registration as the only explanatory variable in the model, a significant linear decrease was observed in shortness of breath, pain and distress (slopes, ?0.26, ?0.22 and ?0.19, respectively). Given that the interaction terms (i.e. PPI × time) were not significantly associated with symptom scores in any of the six symptoms, only PPI was included as the main effect in the final multivariable models. After adjusting for the PPI, shortness of breath, pain and distress significantly improved (slope, ?0.25, ?0.19 and ?0.17; P < 0.001, 0.002 and 0.047, respectively). An improvement in fatigue and distress was observed only in patients treated with a biologically effective dose ≤14.4 Gy.ConclusionShortness of breath, pain and distress improved after radiotherapy. Moreover, a higher PPI was significantly associated with higher symptom scores at all time points, including baseline. In contrast, PPI did not seem to influence the improvement of these symptoms. Regardless of the expected survival, patients receiving radiotherapy for gastric cancer can expect an improvement in shortness of breath, pain and distress over 8 weeks. Multiple-fraction radiotherapy might hamper the improvement in fatigue and distress by its toxicity or treatment burden.     

Biomarker-Driven Studies With Multi-targets and Multi-drugs by Next-Generation Sequencing for Patients With Non–Small-Cell Lung Cancer: An Open-Label,Multi-center,Phase II Adaptive Umbrella Trial and a Real-World Observational Study (CTONG1702&CTONG1705)

BackgroundWith rare genetic variations having been increasingly recognized at a preclinical stage, a variety of early-phase clinical trials have been launched. Due to the low incidence rate of these variations, although the sample size of trials are small, it still needs a large number of patients for screening. With the advent of next-generation sequencing (NGS), multiple genetic variations can be detected simultaneously. Multiple biomarkers and agents can be evaluated using umbrella clinical trials, which rapidly and effectively screen and enroll patients for parallel sub-studies using NGS.Patients and MethodsWe designed an open-label, multi-center, phase II clinical trial CTONG1702. This is an adaptive umbrella trial that will evaluate the efficacy and safety of several biomarker-driven agents, including tyrosine kinase inhibitors (TKIs) and a PD-1 inhibitor, in stage IIIB to IV patients (eighth AJCC) with non-small-cell lung cancer (NSCLC) patients. Patients will be enrolled in parallel sub-studies based on the results of NGS and PD-L1 IHC analysis. Patients who are not eligible for CTONG1702 will be enrolled in the observational real-world study CTONG1705. This study aims to develop a large-scale genomic database and explore the relationship between genetic variations in NSCLC patients and clinical outcomes.ConclusionsThe adaptive umbrella trial will evaluate multi-targets and multi-drugs in advanced NSCLC patients (CTONG1702). In addition, the simultaneously initiated real-world study will provide additional data for clinical practice (CTONG1705).
