RESUMEN
BACKGROUND: Advancements in the field of precision medicine have prompted the European Society for Medical Oncology (ESMO) Precision Medicine Working Group to update the recommendations for the use of tumour next-generation sequencing (NGS) for patients with advanced cancers in routine practice. METHODS: The group discussed the clinical impact of tumour NGS in guiding treatment decision using the ESMO Scale for Clinical Actionability of molecular Targets (ESCAT) considering cost-effectiveness and accessibility. RESULTS: As for 2020 recommendations, ESMO recommends running tumour NGS in advanced non-squamous non-small-cell lung cancer, prostate cancer, colorectal cancer, cholangiocarcinoma, and ovarian cancer. Moreover, it is recommended to carry out tumour NGS in clinical research centres and under specific circumstances discussed with patients. In this updated report, the consensus within the group has led to an expansion of the recommendations to encompass patients with advanced breast cancer and rare tumours such as gastrointestinal stromal tumours, sarcoma, thyroid cancer, and cancer of unknown primary. Finally, ESMO recommends carrying out tumour NGS to detect tumour-agnostic alterations in patients with metastatic cancers where access to matched therapies is available. CONCLUSION: Tumour NGS is increasingly expanding its scope and application within oncology with the aim of enhancing the efficacy of precision medicine for patients with cancer.

BACKGROUND: Successful immunotherapy is restricted to some cancers only, and combinatorial strategies with other drugs could help to improve their efficacy. Here, we monitor T cells in NSCLC model after treatment with cytotoxics (CT) and anti-VEGF drugs, to understand when immune checkpoint inhibitors should be best associated next. METHODS: In vivo study was performed on BALB/c mice grafted with KLN205 cells. Eight treatments were tested including control, cisplatin and pemetrexed as low (LD CT) and full (MTD CT) dose as single agents, flat dose anti-VEGF and the association anti-VEGF + CT. Full immunomonitoring was performed by flow cytometry on tumor, spleen and blood over 3 weeks. RESULTS: Immunomodulatory effect was dependent upon both treatments and time. In tumors, combination groups shown numerical lower Treg cells on Day 21. In spleen, anti-VEGF and LD CT group shown higher CD8/Treg ratio on Day 7; on Day 14, higher T CD4 were observed in both combination groups. Finally, in blood, Tregs were lower and CD8/Treg ratio higher, on Day 14 in both combination groups. On Day 21, CD4 and CD8 T cells were higher in the anti-VEGF + MTD CT group. CONCLUSIONS: Anti-VEGF associated to CT triggers notable increase in CD8/Tregs ratio. Regarding the scheduling, a two-week delay after using anti-VEGF and CT could be the best sequence to optimize antitumor efficacy.

BACKGROUND: Circulating tumor DNA (ctDNA) sequencing is a promising approach for tailoring therapy in patients with cancer. We report hereby the results from a prospective study where we investigated the impact of comprehensive molecular profiling of ctDNA in patients with advanced solid tumors. PATIENTS AND METHODS: Genomic analysis was performed using the FoundationOne Liquid CDx Assay [324 genes, tumor mutational burden (TMB), microsatellite instability status]. Each individual genomic report was reviewed and discussed weekly by a multidisciplinary tumor board (MTB). Actionable targets were classified by ESMO Scale for Clinical Actionability of Molecular Targets (ESCAT) tier leading to molecular-based treatment suggestions wherever it was possible. RESULTS: Between December 2020 and November 2021, 1772 patients with metastatic solid tumors underwent molecular profiling. Median time to assay results was 12 days. Results were contributive for 1658 patients (94%). At least one actionable target was detected in 1059 patients (64%) with a total of 1825 actionable alterations including alteration of the DNA damage repair response pathway (n = 336, 18%), high TMB (>16 mutations/Mb; n = 243, 13%), PIK3CA mutations (n = 150, 8%), ERBB family pathway alterations (n = 127, 7%), PTEN alterations (n = 95, 5%), FGFR alterations (n = 67, 4%) and MET activations (n = 13, 0.7%). The MTB recommended a matched therapy for 597 patients (56%) with a total of 819 therapeutic orientations: clinical trials (n = 639, 78%), off-label/compassionate use (n = 81, 10%), approved drug (n = 51, 6%), and early access program (n = 48, 6%). In total, 122 patients (21%) were treated. Among the assessable patients (n = 107), 4 (4%) had complete response, 35 (33%) had partial response, 27 (25%) had stable disease, and 41 (38%) a progressive disease as best response. The median progression-free survival and median overall survival were 4.7 months (95% confidence interval 2.7-6.7 months) and 8.3 months (95% confidence interval 4.7-11.9 months) respectively. CONCLUSIONS: ctDNA sequencing with a large panel is an efficient approach to match patients with advanced cancer with targeted therapies.

BACKGROUND: The development of targeted agents, such as osimertinib for EGFR-mutated non-small-cell lung cancer (NSCLC), has drastically improved patient outcome, but tumor resistance eventually always occurs. In osimertinib-resistant NSCLC, the emergence of a second molecular driver alteration (such as ALK, RET, FGFR3 fusions or BRAF, KRAS mutations) has been described. Whether those alterations and the activating EGFR mutations occur within a single cancer cell or in distinct cell populations is largely debated. PATIENTS AND METHODS: Tumor sequencing was used to identify the acquired resistance mechanisms to osimertinib in the MATCH-R trial (NCT0251782). We implemented single-cell next-generation sequencing to investigate tumor heterogeneity on patient's frozen tissues in which multiple alterations have been identified. Patient-derived models, cell lines, and patient-derived xenografts were exposed to specific inhibitors to investigate combination treatment strategies. RESULTS: Among the 45 patients included in MATCH-R who progressed on osimertinib, 9 developed a second targetable alteration (n = 2 FGFR3-TACC3, n = 1 KIF5B-RET, n = 1 STRN-ALK fusions; n = 2 BRAFV600E, n = 1 KRASG12V, n = 1 KRASG12R, n = 1 KRASG12D mutations). Single-cell analysis revealed that the two driver alterations coexist within one single cancer cell in the four patients whose frozen samples were fully contributive. A high degree of heterogeneity within samples and sequential acquisitions of molecular events were highlighted. A combination treatment concomitantly targeting the two driver alterations was required on the corresponding patient-derived models to restore cell sensitivity, which was consistent with clinical data showing efficacy of brigatinib in the patient with ALK fusion after progression to osimertinib and crizotinib administered sequentially. CONCLUSIONS: Distinct molecular driver alterations at osimertinib resistance coexist with initial EGFR mutations in single cancer cells. The clonal evolution of cancer cell populations emphasized their heterogeneity leading to osimertinib relapse. Combining two targeted treatments is effective to achieve clinical benefit.

BACKGROUND: The discovery of immune checkpoint inhibitors (ICIs) has revolutionized the systemic approach to cancer treatment. Most patients receiving ICIs, however, do not derive benefits. Therefore, it is crucial to identify reliable predictive biomarkers of response to ICIs. One important pathway in regulating immune cell reactivity is L-arginine (ARG) metabolism, essential to T-cell activation. We therefore aimed to evaluate the association between baseline plasma ARG levels and the clinical benefit of ICIs. PATIENTS AND METHODS: The correlation between ARG levels and clinical ICI activity was assessed by analyzing plasma samples obtained before treatment onset in two independent cohorts of patients with advanced cancer included in two institutional molecular profiling programs (BIP, NCT02534649, n = 77; PREMIS, NCT03984318, n = 296) and from patients in a phase 1 first-in-human study of budigalimab monotherapy (NCT03000257). Additionally, the correlation between ARG levels and ICI efficacy in preclinical settings was evaluated using a syngeneic mouse model of colorectal cancer responsive to ICIs. Using matched peripheral blood mononuclear cell (PBMC) plasma samples, we analyzed the correlation between ARG levels and PBMC features through multiplexed flow cytometry analysis. RESULTS: In both discovery and validation cohorts, low ARG levels at baseline (<42 µM) were significantly and independently associated with a worse clinical benefit rate, progression-free survival, and overall survival. Moreover, at the preclinical level, the tumor rejection rate was significantly higher in mice with high baseline ARG levels than in those with low ARG levels (85.7% versus 23.8%; P = 0.004). Finally, PBMC immunophenotyping showed that low ARG levels were significantly associated with increased programmed death-ligand 1 expression in several immune cell subsets from the myeloid lineage. CONCLUSIONS: We demonstrate that baseline ARG levels predict ICI response. Plasma ARG quantification may therefore represent an attractive biomarker to tailor novel therapeutic regimens targeting the ARG pathway in combination with ICIs.

BACKGROUND: We evaluated MK-4621, an oligonucleotide that binds and activates retinoic acid-inducible gene I (RIG-I), as monotherapy (NCT03065023) and in combination with the anti-programmed death 1 antibody pembrolizumab (NCT03739138). PATIENTS AND METHODS: Patients were ≥ 18 years with histologically/cytologically confirmed advanced/metastatic solid tumors with injectable lesions. MK-4621 (0.2â0.8 mg) was administered intratumorally as a stable formulation with jetPEI™ twice weekly over a 4-week cycle as monotherapy and weekly in 3-week cycles for up to 6 cycles in combination with 200 mg pembrolizumab every 3 weeks for up to 35 cycles. Primary endpoints were dose-limiting toxicities (DLTs), treatment-related adverse events (AEs), and treatment discontinuation due to AEs. RESULTS: Fifteen patients received MK-4621 monotherapy and 30 received MK-4621 plus pembrolizumab. The only DLT, grade 3 pleural effusion that subsequently resolved, occurred in a patient who received MK-4621/jetPEI™ 0.8 mg plus pembrolizumab. 93% of patients experienced ≥ 1 treatment-related AE with both monotherapy and combination therapy. No patients experienced an objective response per RECIST v1.1 with MK-4621 monotherapy; 4 (27%) had stable disease. Three (10%) patients who received combination therapy had a partial response. Serum and tumor biomarker analyses provided evidence that MK-4621 treatment induced an increase in gene expression of interferon signaling pathway members and associated chemokines and cytokines. CONCLUSIONS: Patients treated with MK-4621 monotherapy or in combination with pembrolizumab experienced tolerable safety and modest antitumor activity, and there was evidence that MK-4621 activated the RIG-I pathway. At the doses tested, MK-4621 did not confer meaningful clinical benefit. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03065023 and NCT03739138.

Rat sarcoma (RAS) is the most frequently mutated oncogene in human cancer, with Kirsten rat sarcoma (KRAS) being the most commonly mutated RAS isoform. Overall, KRAS accounts for 85% of RAS mutations observed in human cancers and is present in 35% of lung adenocarcinomas (LUADs). While the use of targeted therapies and immune checkpoint inhibitors (CPIs) has drastically changed the treatment landscape of advanced non-small-cell lung cancer (NSCLC) in recent years, historic attempts to target KRAS (both direct and indirect approaches) have had little success, and no KRAS-specific targeted therapies have been approved to date for patients in this molecular subset of NSCLC. With the discovery by Ostrem, Shokat, and colleagues of the switch II pocket on the surface of the active and inactive forms of KRAS, we now have an improved understanding of the complex interactions involved in the RAS family of signaling proteins which has led to the development of a number of promising direct KRASG12C inhibitors, such as sotorasib and adagrasib. In previously treated patients with KRASG12C-mutant NSCLC, clinical activity has been shown for both sotorasib and adagrasib monotherapy; these data suggest promising new treatment options are on the horizon. With the stage now set for a new era in the treatment of KRASG12C-mutated NSCLC, many questions remain to be answered in order to further elucidate the mechanisms of resistance, how best to use combination strategies, and if KRASG12C inhibitors will have suitable activity in earlier lines of therapy for patients with advanced/metastatic NSCLC.

Next-generation sequencing (NGS) allows sequencing of a high number of nucleotides in a short time frame at an affordable cost. While this technology has been widely implemented, there are no recommendations from scientific societies about its use in oncology practice. The European Society for Medical Oncology (ESMO) is proposing three levels of recommendations for the use of NGS. Based on the current evidence, ESMO recommends routine use of NGS on tumour samples in advanced non-squamous non-small-cell lung cancer (NSCLC), prostate cancers, ovarian cancers and cholangiocarcinoma. In these tumours, large multigene panels could be used if they add acceptable extra cost compared with small panels. In colon cancers, NGS could be an alternative to PCR. In addition, based on the KN158 trial and considering that patients with endometrial and small-cell lung cancers should have broad access to anti-programmed cell death 1 (anti-PD1) antibodies, it is recommended to test tumour mutational burden (TMB) in cervical cancers, well- and moderately-differentiated neuroendocrine tumours, salivary cancers, thyroid cancers and vulvar cancers, as TMB-high predicted response to pembrolizumab in these cancers. Outside the indications of multigene panels, and considering that the use of large panels of genes could lead to few clinically meaningful responders, ESMO acknowledges that a patient and a doctor could decide together to order a large panel of genes, pending no extra cost for the public health care system and if the patient is informed about the low likelihood of benefit. ESMO recommends that the use of off-label drugs matched to genomics is done only if an access programme and a procedure of decision has been developed at the national or regional level. Finally, ESMO recommends that clinical research centres develop multigene sequencing as a tool to screen patients eligible for clinical trials and to accelerate drug development, and prospectively capture the data that could further inform how to optimise the use of this technology.

BACKGROUND: BRAF mutations occurring in 1%-5% of patients with non-small-cell lung cancer (NSCLC) are therapeutic targets for these cancers but the impact of the exact mutation on clinical activity is unclear. The French National Cancer Institute (INCA) launched the AcSé vemurafenib trial to assess the efficacy and safety of vemurafenib in cancers with various BRAF mutations. We herein report the results of the NSCLC cohort. PATIENTS AND METHODS: Tumour samples were screened for BRAF mutations in INCA-certified molecular genetic centres. Patients with BRAF-mutated tumours progressing after ≥1 line of treatment were proposed vemurafenib 960 mg twice daily. Between October 2014 and July 2018, 118 patients were enrolled in the NSCLC cohort. The primary outcome was the objective response rate (ORR) assessed every 8 weeks (RECIST v1.1). A sequential Bayesian approach was planned with an inefficacy bound of 10% for ORR. If no early stopping occurred, the treatment was of interest if the estimated ORR was ≥30% with a 90% probability. Secondary outcomes were tolerance, response duration, progression-free survival (PFS), and overall survival (OS). RESULTS: Of the 118 patients enrolled, 101 presented with a BRAFV600 mutation and 17 with BRAFnonV600 mutations; the median follow-up was 23.9 months. In the BRAFnonV600 cohort, no objective response was observed and this cohort was stopped. In the BRAFV600 cohort, 43/96 patients had objective responses. The mean Bayesian estimated success rate was 44.9% [95% confidence intervals (CI) 35.2%-54.8%]. The ORR had a 99.9% probability of being ≥30%. Median response duration was 6.4 months, median PFS was 5.2 months (95% CI 3.8-6.8), and OS was 10 months (95% CI 6.8-15.7). The vemurafenib safety profile was consistent with previous publications. CONCLUSION: Routine biomarker screening of NSCLC should include BRAFV600 mutations. Vemurafenib monotherapy is effective for treating patients with BRAFV600-mutated NSCLC but not those with BRAFnonV600 mutations. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02304809.

BACKGROUND: In 2013, the French National Cancer Institute initiated the AcSé program to provide patients with secure access to targeted therapies outside of their marketed approvals. Efficacy and safety was then assessed using a two-stage Simon phase II trial design. When the study design was designed, crizotinib was approved only as monotherapy for adults with anaplastic lymphoma kinase plus non-small-cell lung cancers (NSCLC). PATIENTS AND METHODS: Advanced NSCLC patients with c-MET ≥6 copies, c-MET-mutated, or ROS-1-translocated tumours were enrolled in one of the three cohorts. Patients were treated with crizotinib 250 mg twice daily. Efficacy was assessed using the objective response rate (ORR) after two cycles of crizotinib as primary outcome. Secondary outcomes included disease control rate at four cycles, best ORR, progression-free survival, overall survival, and drug tolerance. RESULTS: From August 2013 to March 2018, 5606 patients had their tumour tested for crizotinib targeted molecular alterations: 252 patients had c-MET ≥6 copies, 74 c-MET-mutation, and 78 ROS-1-translocated tumour. Finally, 25 patients in the c-MET ≥6 copies cohort, 28 in the c-MET-mutation cohort, and 37 in the ROS-1-translocation cohort were treated in the phase II trial. The ORR was 16% in the c-MET ≥6 copies cohort, 10.7% in the mutated, and 47.2% in the ROS-1 cohort. The best ORR during treatment was 32% in the c-MET-≥6 copies cohort, 36% in the c-MET-mutated, and 69.4% in the ROS-1-translocation cohort. Safety data were consistent with that previously reported. CONCLUSIONS: Crizotinib activity in patients with ROS1-translocated tumours was confirmed. In the c-MET-mutation and c-MET ≥6 copies cohorts, despite insufficient ORR after two cycles of crizotinib, there are signs of late response not sufficient to justify the development of crizotinib in this indication. The continued targeting of c-MET with innovative therapies appears justified. CLINICAL TRIAL NUMBER: NCT02034981.

BACKGROUND: Anti-PD1/PD-L1 directed immune checkpoint inhibitors (ICI) are widely used to treat patients with advanced non-small-cell lung cancer (NSCLC). The activity of ICI across NSCLC harboring oncogenic alterations is poorly characterized. The aim of our study was to address the efficacy of ICI in the context of oncogenic addiction. PATIENTS AND METHODS: We conducted a retrospective study for patients receiving ICI monotherapy for advanced NSCLC with at least one oncogenic driver alteration. Anonymized data were evaluated for clinicopathologic characteristics and outcomes for ICI therapy: best response (RECIST 1.1), progression-free survival (PFS), and overall survival (OS) from ICI initiation. The primary end point was PFS under ICI. Secondary end points were best response (RECIST 1.1) and OS from ICI initiation. RESULTS: We studied 551 patients treated in 24 centers from 10 countries. The molecular alterations involved KRAS (n = 271), EGFR (n = 125), BRAF (n = 43), MET (n = 36), HER2 (n = 29), ALK (n = 23), RET (n = 16), ROS1 (n = 7), and multiple drivers (n = 1). Median age was 60 years, gender ratio was 1 : 1, never/former/current smokers were 28%/51%/21%, respectively, and the majority of tumors were adenocarcinoma. The objective response rate by driver alteration was: KRAS = 26%, BRAF = 24%, ROS1 = 17%, MET = 16%, EGFR = 12%, HER2 = 7%, RET = 6%, and ALK = 0%. In the entire cohort, median PFS was 2.8 months, OS 13.3 months, and the best response rate 19%. In a subgroup analysis, median PFS (in months) was 2.1 for EGFR, 3.2 for KRAS, 2.5 for ALK, 3.1 for BRAF, 2.5 for HER2, 2.1 for RET, and 3.4 for MET. In certain subgroups, PFS was positively associated with PD-L1 expression (KRAS, EGFR) and with smoking status (BRAF, HER2). CONCLUSIONS: : ICI induced regression in some tumors with actionable driver alterations, but clinical activity was lower compared with the KRAS group and the lack of response in the ALK group was notable. Patients with actionable tumor alterations should receive targeted therapies and chemotherapy before considering immunotherapy as a single agent.

Background: Long-term data with immune checkpoint inhibitors in non-small-cell lung cancer (NSCLC) are limited. Two phase III trials demonstrated improved overall survival (OS) and a favorable safety profile with the anti-programmed death-1 antibody nivolumab versus docetaxel in patients with previously treated advanced squamous (CheckMate 017) and nonsquamous (CheckMate 057) NSCLC. We report results from ≥3 years' follow-up, including subgroup analyses of patients with liver metastases, who historically have poorer prognosis among patients with NSCLC. Patients and methods: Patients were randomized 1 : 1 to nivolumab (3 mg/kg every 2 weeks) or docetaxel (75 mg/m2 every 3 weeks) until progression or discontinuation. The primary end point of each study was OS. Patients with baseline liver metastases were pooled across studies by treatment for subgroup analyses. Results: After 40.3 months' minimum follow-up in CheckMate 017 and 057, nivolumab continued to show an OS benefit versus docetaxel: estimated 3-year OS rates were 17% [95% confidence interval (CI), 14% to 21%] versus 8% (95% CI, 6% to 11%) in the pooled population with squamous or nonsquamous NSCLC. Nivolumab was generally well tolerated, with no new safety concerns identified. Of 854 randomized patients across both studies, 193 had baseline liver metastases. Nivolumab resulted in improved OS compared with docetaxel in patients with liver metastases (hazard ratio, 0.68; 95% CI, 0.50-0.91), consistent with findings from the overall pooled study population (hazard ratio, 0.70; 95% CI, 0.61-0.81). Rates of treatment-related hepatic adverse events (primarily grade 1-2 liver enzyme elevations) were slightly higher in nivolumab-treated patients with liver metastases (10%) than in the overall pooled population (6%). Conclusions: After 3 years' minimum follow-up, nivolumab continued to demonstrate an OS benefit versus docetaxel in patients with advanced NSCLC. Similarly, nivolumab demonstrated an OS benefit versus docetaxel in patients with liver metastases, and remained well tolerated. Clinical trial registration: CheckMate 017: NCT01642004; CheckMate 057: NCT01673867.

WHAT IS KNOWN AND OBJECTIVE: With the increasing use of cancer chemotherapy agents, hypersensitivity reactions are commonly encountered. The allergic clinical symptoms are variable and unpredictable. The aim of this study was to identify the characteristics of hypersensitivity reactions and to assess the value of skin tests for platinum salts and pemetrexed in the treatment of patients with non-small cell lung cancers or malignant pleural mesothelioma. METHODS: A single-centre retrospective study was performed for 2 years. Patients treated with the drugs of interest for an advanced or metastatic non-small cell lung cancers or malignant pleural mesothelioma and who experienced hypersensitivity reactions symptoms were eligible for this study. Clinical symptoms of hypersensitivity reactions, population characteristics and administered chemotherapy regimens were identified. RESULTS: The hypersensitivity reactions frequency was rare (1.2%) and concerned 17 patients in our study. Typical clinical features of immediate hypersensitivity reactions associated with treatment were observed for nine patients (anaphylactic reactions for three cases, angioedema and hypotension associated with asthenia and heat in one case, respectively, and other cutaneous symptoms in the remaining four cases). Skin tests were positive in three patients, but only for platinum salts. The outcome after reintroduction of a negatively tested platinum salt allowed us to calculate a negative predictive value for platinum salt skin tests of 100%. For pemetrexed, skin tests were negative for all patients. WHAT IS NEW AND CONCLUSION: Skin tests could be used to diagnose hypersensitivity reactions with platinum salts or to evaluate the possibility of cross-reactions between two platinum salts. A negative skin test may predict with reasonable reliability the absence of future hypersensitivity reactions in case of reintroduction of drug infusion. Because the IgE-mediated mechanism has never been demonstrated for pemetrexed, skin tests are not valid and have no diagnostic value for this molecule. Because hypersensitivity reactions are potentially fatal adverse events, we recommend that patients who experience a hypersensitivity reactions onset should be monitored closely and clinicians must be aware of hypersensitivity reaction signs.

BACKGROUND: Small-cell lung cancer (SCLC) represents one of the most aggressive forms of lung cancer. Despite the fair sensitivity of SCLC to chemotherapy and radiotherapy, the current standard treatment regimens have modest survival rates and are associated with potential life-threatening adverse events. Therefore, research into new optimised regimens that increase drug efficacy while respecting toxicity constraints is of primary importance. METHODS: A PK/PD model for the combination of cisplatin and etoposide to treat extensive-stage SCLC patients was generated. The model takes into consideration both the efficacy of the drugs and their haematological toxicity. Using optimisation techniques, the model can be used to propose new regimens. RESULTS: Three new regimens with varying timing for combining cisplatin and etoposide have been generated that respect haematological toxicity constraints and achieve better or similar tumour regression. The proposed regimens are: (1) Protocol OP1: etoposide 80 mg m-2 over 1 h D1, followed by a long infusion 12 h later (over 3 days) of 160 mg m-2 plus cisplatin 80 mg m-2 over 1 h D1, D1-D1 21 days; (2) Protocol OP2: etoposide 80 mg m-2 over 1 h D1, followed by a long infusion 12 h later (over 4 days) of 300 mg m-2 plus cisplatin 100 mg m-2 over 1 h D1, D1-D1 21 days; and (3) Protocol OP3: etoposide 40 mg m-2 over 1 h, followed by a long infusion 6 h later (3 days) of 105 mg m-2 plus cisplatin 50 mg m-2 over 1 h, D1-D1 14 days. CONCLUSIONS: Mathematical modelling can help optimise the design of new cisplatin plus etoposide regimens for managing extensive-stage SCLC patients.

BACKGROUND: Eribulin is a microtubule dynamics inhibitor with a novel mechanism of action. This phase 3 study aimed to compare overall survival (OS) in patients with heavily pretreated non-small cell lung cancer (NSCLC) receiving eribulin to treatment of physician's choice (TPC). PATIENTS AND METHODS: Patients with advanced NSCLC who had received ≥2 prior therapies, including platinum-based doublet and epidermal growth factor receptor tyrosine kinase inhibitor, were randomly assigned to receive eribulin or TPC (gemcitabine, pemetrexed, vinorelbine, docetaxel). The primary endpoint was OS. Secondary endpoints were progression-free survival and objective response rate. RESULTS: Five hundred and forty patients were randomized to either eribulin (n = 270) or TPC (n = 270). Median OS for eribulin and TPC was the same: 9.5 months [hazard ratio (HR): 1.16; 95% confidence interval: 0.95-1.41; P = 0.13]. Progression-free survival for eribulin and TPC was 3.0 and 2.8 months, respectively (HR: 1.09; 95% confidence interval: 0.90-1.32; P = 0.39). The objective response rate was 12% for eribulin and 15% for TPC. Clinical benefit rate (eribulin, 57%; TPC, 55%) and disease control rate (eribulin, 63%; TPC, 58%) were similar between treatment arms. The most common adverse event was neutropenia, which occurred in 57% of eribulin patients and 49% of TPC patients at all grades. Other non-hematologic side-effects were manageable and similar in both groups except for peripheral sensory neuropathy (all grades; eribulin, 16%; TPC, 9%). CONCLUSION: This phase 3 study did not demonstrate superiority of eribulin over TPC with regard to overall survival. However, eribulin does show activity in the third-line setting for NSCLC.

BACKGROUND: Adjuvant treatment in resected stage I non-small-cell lung cancer (NSCLC) is generally not recommended. Pazopanib is an oral tyrosine kinase inhibitor of VEGFR-1/2/3 and PDGFR-α/ß. We explored the feasibility and efficacy of adjuvant pazopanib in this population. PATIENTS AND METHODS: In this double-blind phase II/III trial, patients with resected stage I NSCLC were randomized to placebo or pazopanib 800 mg/day (P800) for 6 months with a two-step Fleming design. The primary endpoint was compliance (percentage of patients receiving ≥3 months pazopanib). From the interim analysis after 64 patients were included, the IDMC recommended reducing to pazopanib 400 mg/day (P400) due to insufficient compliance, with a one-step Fleming. Although unplanned, survival data were analyzed. RESULTS: A total of 71 patients were enrolled in each arm; 61% were male, 91% were smokers, median age was 60 years, 80% had pathological stage IA, and 16% had squamous cell carcinoma. Pazopanib compliance was 38% [95% confidence interval (CI) 23-55] with P800, increasing to 69% (95% CI 50-84; P = 0.027) with P400. Two patients had grade 4 toxicities with P800. The most common grade 3 toxicities were increased transaminases (16%), hypertension (13%), and diarrhea (9%) with P800, and gastrointestinal disorders (16%; 6% diarrhea) and hypertension (6%) with P400. Median follow-up was 47 months. Three-year recurrence-free survival was 76% (95% CI 65%-86%) with pazopanib and 83% (95% CI 74%-92%) with placebo [hazard ratio = 1.3 (95% CI 0.6-2.7), P = 0.53]. Five-year overall survival was 83% (95% CI 72-94) with pazopanib and 94% [95% CI 88-100] with placebo [hazard ratio = 1.8 (95% CI 0.6-5.5), P = 0.26]. CONCLUSIONS: In resected stage I NSCLC patients adjuvant 400 mg/day pazopanib but not 800 mg/day was feasible, although possibly infra-therapeutic and failed to improve relapse-free survival.

BACKGROUND: EGFR mutations cause inconsistent response to EGFR tyrosine-kinase inhibitors (TKI). To better understand these features, we reviewed all cases of EGFR-mutated non-small-cell lung cancer collected in the Biomarkers France database. PATIENTS AND METHODS: Of 17 664 patients, 1837 (11%) with EGFR-mutated non-small-cell lung cancer were retrospectively analyzed for clinical and molecular characteristics. Results were correlated with survival and treatment response for the 848 stage IV patients. RESULTS: EGFR exon 18, 19, 20 and 21 mutations were found in 102 (5.5%), 931 (51%), 102 (5.5%) and 702 (38%) patients, respectively. Over 50% of exon 18 and 20 mutated patients were smokers. The median follow-up was 51.7 months. EGFR mutation type was prognostic of overall survival (OS) versus wild-type {exon 19: hazard ratio (HR)=0.51 [95% confidence interval (CI): 0.41-0.64], P < 0.0001; exon 21: HR = 0.76 (95% CI: 0.61-0.95), P = 0.002; exon 20: HR = 1.56 (95% CI: 1.02-2.38), P = 0.004}. EGFR mutation type was prognostic of progression-free survival versus wild-type [exon 19: HR = 0.62 (95% CI: 0.49-0.78), P < 0.0001; exon 20: HR = 1.46 (95% CI: 0.96-2.21), P = 0.07]. First-line treatment choice did not influence OS in multivariate analysis. First-line TKI predicted improved progression-free survival versus chemotherapy [HR = 0.67 (95% CI: 0.53-0.85), P = 0.001]. OS was longer for del19 versus L858R, which was associated with better OS compared with other exon 21 mutations, including L861Q. TKI improved survival in patients with exon 18 mutations, while chemotherapy was more beneficial for exon 20-mutated patients. CONCLUSION: EGFR mutation type can inform the most appropriate treatment. Therapeutic schedule had no impact on OS in our study, although TKI should be prescribed in first-line considering the risk of missing the opportunity to use this treatment.

BACKGROUND: HER2 mutations have been identified as oncogenic drivers in lung cancers and are found in 1-2% of lung adenocarcinomas. There is, to date, no standard of care for these patients. We thus aim to study the therapeutic outcomes of patients harboring HER2 mutations and establish the efficacy of various drug regimens. PATIENTS AND METHODS: This retrospective cohort study in European centers assessed patients with advanced non-small-cell lung cancer (NSCLC), a known HER2 exon-20 insertion, treated with chemotherapy and/or HER2-targeted drugs. RESULTS: We identified 101 eligible patients from 38 centers: median age 61 years (range: 30-87), 62.4% women, 60.4% never-smokers. All tumors were adenocarcinomas. Concomitant EGFR mutations, ALK translocations, and ROS translocations were observed in 5, 1, and 1 patients, respectively. The median number of treatment lines was 3 (range: 1-11). The median overall survival was 24 months. Overall response rate (ORR) and the median progression-free survival (PFS) with conventional chemotherapy (excluding targeted therapies) were 43.5% and 6 months in first-line (n = 93), and 10% and 4.3 months in second-line (n = 52) therapies. Sixty-five patients received HER2-targeted therapies: trastuzumab = 57, neratinib = 14, afatinib = 9, lapatinib = 5, T-DM1 = 1. ORR was 50.9% and PFS was 4.8 months with trastuzumab or T-DM1. CONCLUSION: This series shows the chemosensitivity of HER2-driven NSCLC, and the potential interest of HER2-targeted agents. Our results should help to define the best therapeutic strategy for these patients and to orient future clinical trials.
