Background: The role of adding immune checkpoint inhibitors to chemotherapy in tyrosine kinase inhibitor (TKI)-resistant, epidermal growth factor receptor (EGFR)-mutant non-small-cell lung cancer (NSCLC) remains unknown. We carried out a meta-analysis to comprehensively assess the role of chemoimmunotherapy combinations, with and without vascular endothelial growth factor (VEGF) inhibition, in TKI-resistant, EGFR-mutant NSCLC., Materials and Methods: We systemically searched PubMed/MEDLINE and the proceedings of key annual meetings between 2018 and 2024 to identify randomized studies that evaluated chemoimmunotherapy combinations and included patients with EGFR-mutant NSCLC. Six randomized, phase III trials (CheckMate-722, KEYNOTE-789, ORIENT-31, IMpower150, IMpower151, and ATTLAS) were included in the meta-analysis. To compare progression-free survival (PFS) and overall survival (OS) outcomes, we extracted hazard ratio (HR) and 95% confidence interval (CI) for PFS and OS for EGFR-mutant subgroups from each study. We used the fixed effects model with inverse variance weighting to estimate the overall effect sizes for PFS and OS for chemoimmunotherapy combinations (with and without VEGF inhibitors) versus control arms., Results: A total of 1772 patients with EGFR-mutant NSCLC were included. Adding programmed death-ligand 1 [PD-(L)1] inhibitors to chemotherapy significantly improved PFS (HR 0.77, 95% CI 0.67-0.88, P = 0.0002). This effect was greater when both PD-(L)1 and VEGF inhibition were utilized (PFS: HR 0.62, 95% CI 0.52-0.73, P < 0.0001). The pooled OS HR was 0.86 (95% CI 0.75-1.00, P = 0.0429) with the chemotherapy + PD-(L)1 combinations and 0.98 (95% CI 0.79-1.22, P = 0.8463) with dual PD-(L)1/VEGF inhibition., Conclusions: Despite modest improvements in PFS, most pronounced when both PD-(L)1 and VEGF inhibitors are added to chemotherapy, neither strategy led to clinically meaningful improvements in OS. Our results do not support the broad use of chemoimmunotherapy combinations in TKI-resistant, EGFR-mutant lung cancer. Novel immunotherapy approaches are urgently needed for oncogene-driven NSCLC., (Copyright © 2024 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Purpose: The phase III CheckMate 722 trial (ClinicalTrials.gov identifier: NCT02864251) evaluated nivolumab plus chemotherapy versus chemotherapy in patients with epidermal growth factor receptor ( EGFR )-mutated metastatic non-small-cell lung cancer (NSCLC) after disease progression on EGFR tyrosine kinase inhibitors (TKIs)., Methods: Patients with disease progression after first- or second-generation EGFR TKI therapy (without EGFR T790M mutation) or osimertinib (with/without T790M mutation) were randomly assigned 1:1 to nivolumab (360 mg once every 3 weeks) plus platinum-doublet chemotherapy (once every 3 weeks) or platinum-doublet chemotherapy alone (once every 3 weeks) for four cycles. Primary end point was progression-free survival (PFS). Secondary end points included 9- and 12-month PFS rates, overall survival (OS), objective response rate (ORR), and duration of response (DOR)., Results: Overall, 294 patients were randomly assigned. At final analysis (median follow-up, 38.1 months), PFS was not significantly improved with nivolumab plus chemotherapy versus chemotherapy (median, 5.6 v 5.4 months; hazard ratio [HR], 0.75 [95% CI, 0.56 to 1.00]; P = .0528), with 9- and 12-month PFS rates of 25.9% versus 19.8%, and 21.2% versus 15.9%, respectively. Post hoc PFS subgroup analyses showed a trend favoring nivolumab plus chemotherapy in patients with tumors harboring sensitizing EGFR mutations (HR, 0.72 [95% CI, 0.54 to 0.97]), one line of previous EGFR TKI (0.72 [95% CI, 0.54 to 0.97]), or both (0.64 [95% CI, 0.47 to 0.88]). Median OS was 19.4 months with nivolumab plus chemotherapy versus 15.9 months with chemotherapy, while ORR was 31.3% versus 26.7%, and median DOR was 6.7 versus 5.6 months, respectively. Grade 3/4 treatment-related adverse events occurred in 44.7% and 29.4% of patients treated with nivolumab plus chemotherapy and chemotherapy alone, respectively., Conclusion: Nivolumab plus chemotherapy did not significantly improve PFS versus chemotherapy in patients with EGFR- mutated metastatic NSCLC previously treated with EGFR TKIs. No new safety signals were identified.

TGF-β induces senescence in embryonic tissues. Whether TGF-β in the hypoxic tumor microenvironment (TME) induces senescence in cancer and how the ensuing senescence-associated secretory phenotype (SASP) remodels the cellular TME to influence immune checkpoint inhibitor (ICI) responses are unknown. We show that TGF-β induces a deeper senescent state under hypoxia than under normoxia; deep senescence correlates with the degree of E2F suppression and is marked by multinucleation, reduced reentry into proliferation, and a distinct 14-gene SASP. Suppressing TGF-β signaling in tumors in an immunocompetent mouse lung cancer model abrogates endogenous senescent cells and suppresses the 14-gene SASP and immune infiltration. Untreated human lung cancers with a high 14-gene SASP display immunosuppressive immune infiltration. In a lung cancer clinical trial of ICIs, elevated 14-gene SASP is associated with increased senescence, TGF-β and hypoxia signaling, and poor progression-free survival. Thus, TME-induced senescence may represent a naturally occurring state in cancer, contributing to an immune-suppressive phenotype associated with immune therapy resistance., Competing Interests: Declaration of interests A.

Background: First-line nivolumab plus ipilimumab prolongs survival versus chemotherapy in advanced non-small-cell lung cancer (NSCLC). We further characterized clinical benefit with this regimen in a large pooled patient population and assessed the effect of response on survival., Patients and Methods: Data were pooled from four studies of first-line nivolumab plus ipilimumab in advanced NSCLC (CheckMate 227 Part 1, 817 cohort A, 568 Part 1, and 012). Overall survival (OS), progression-free survival (PFS), objective response rate, duration of response, and safety were assessed. Landmark analyses of OS by response status at 6 months and by tumor burden reduction in responders to nivolumab plus ipilimumab were also assessed., Results: In the pooled population (N = 1332) with a minimum follow-up of 29.1-58.9 months, median OS was 18.6 months, with a 3-year OS rate of 35%; median PFS was 5.4 months (3-year PFS rate, 17%). Objective response rate was 36%; median duration of response was 23.7 months, with 38% of responders having an ongoing response at 3 years. In patients with tumor programmed death-ligand 1 (PD-L1) <1%, ≥1%, 1%-49%, or ≥50%, 3-year OS rates were 30%, 38%, 30%, and 48%. Three-year OS rates were 30% and 38% in patients with squamous or non-squamous histology. Efficacy outcomes in patients aged ≥75 years were similar to the overall pooled population (median OS, 20.1 months; 3-year OS rate, 34%). In the pooled population, responders to nivolumab plus ipilimumab at 6 months had longer post-landmark OS than those with stable or progressive disease; 3-year OS rates were 66%, 22%, and 14%, respectively. Greater depth of response was associated with prolonged survival; in patients with tumor burden reduction ≥80%, 50% to <80%, or 30% to <50%, 3-year OS rates were 85%, 72%, and 44%, respectively. No new safety signals were identified in the pooled population., Conclusion: Long-term survival benefit and durable response with nivolumab plus ipilimumab in this large patient population further support this first-line treatment option for advanced NSCLC., Competing Interests: Disclosure HB reports advisory/consulting fees, travel, accommodation, and expenses from Amgen, Bristol Myers Squibb, Genentech, Lilly, Merck, and Novartis; advisory/consulting fees from AbbVie, AstraZeneca, BioNTech AG, Boehringer Ingelheim, Cantargia AB, EMD Serono, Genmab, HUYA Bioscience International, Nuclaei, Pfizer, PharmaMar, Regeneron, Rgenix, Sonnet, Takeda, and Trovagene; honoraria from Amgen, Axiom Biotechnologies, Bristol Myers Squibb, Celgene, and Pfizer; research funding from Bristol Myers Squibb, Celgene, Lilly, Merck, and Millennium; stock interest with Nuclaei, Rgenix, and Sonnet; travel, accommodation, and expenses from Clovis Oncology; data safety monitoring board with Incyte and University of Pennsylvania; and ad boards with Guardant, Natera, and OncoCyte.

Background: RET fusions are present in 1%-2% of non-small-cell lung cancer (NSCLC). Pralsetinib, a highly potent, oral, central nervous system-penetrant, selective RET inhibitor, previously demonstrated clinical activity in patients with RET fusion-positive NSCLC in the phase I/II ARROW study, including among treatment-naive patients. We report an updated analysis from the ARROW study., Patients and Methods: ARROW is a multi-cohort, open-label, phase I/II study. Eligible patients were ≥18 years of age with locally advanced or metastatic solid tumours and an Eastern Cooperative Oncology Group performance status of 0-2 (later 0-1). Patients initiated pralsetinib at the recommended phase II dose of 400 mg once daily until disease progression, intolerance, consent withdrawal, or investigator's decision. The co-primary endpoints (phase II) were overall response rate (ORR) by blinded independent central review and safety., Results: Between 17 March 2017 and 6 November 2020 (data cut-off), 281 patients with RET fusion-positive NSCLC were enrolled. The ORR was 72% [54/75; 95% confidence interval (CI) 60% to 82%] for treatment-naive patients and 59% (80/136; 95% CI 50% to 67%) for patients with prior platinum-based chemotherapy (enrolment cut-off for efficacy analysis: 22 May 2020); median duration of response was not reached for treatment-naive patients and 22.3 months for prior platinum-based chemotherapy patients. Tumour shrinkage was observed in all treatment-naive patients and in 97% of patients with prior platinum-based chemotherapy; median progression-free survival was 13.0 and 16.5 months, respectively. In patients with measurable intracranial metastases, the intracranial response rate was 70% (7/10; 95% CI 35% to 93%); all had received prior systemic treatment. In treatment-naive patients with RET fusion-positive NSCLC who initiated pralsetinib by the data cut-off (n = 116), the most common grade 3-4 treatment-related adverse events (TRAEs) were neutropenia (18%), hypertension (10%), increased blood creatine phosphokinase (9%), and lymphopenia (9%). Overall, 7% (20/281) discontinued due to TRAEs., Conclusions: Pralsetinib treatment produced robust efficacy and was generally well tolerated in treatment-naive patients with advanced RET fusion-positive NSCLC.

Background: Tumor infiltrating lymphocytes (TILs) reflect adaptive antitumor immune responses in cancer and are generally associated with favorable prognosis. However, the relationships between TILs subsets and their spatial arrangement with clinical benefit from immune checkpoint inhibitors (ICI) in non-small cell lung cancer (NSCLC) remains less explored., Methods: We used multiplexed quantitative immunofluorescence panels to determine the association of major TILs subpopulations, CD8 + cytotoxic T cells, CD4 + helper T cells and CD20 + B cells, and T cell exhaustion markers, programmed cell death protein-1 (PD-1),lymphocyte-activation gene 3 (LAG-3) and T cell immunoglobulin mucin-3 (TIM-3) with outcomes in a multi-institutional cohort of baseline tumor samples from 179 patients with NSCLC treated with ICI. The analysis of full-face tumor biopsies including numerous fields of view allowed a detailed spatial analysis and assessment of tumor immune heterogeneity using a multiparametric quadratic entropy metric (Rao's Q Index (RQI))., Results: TILs were preferentially located in the stromal tissue areas surrounding tumor-cell nests and CD8 + T cells were the most abundant subset. Higher density of stromal CD8 + cytotoxic T cells was significantly associated with longer survival, and this effect was more prominent in programmed death ligand-1 (PD-L1) positive cases. The role of baseline T cell infiltration to stratify PD-L1 expressing cases was confirmed measuring the T cell receptor-burden in an independent NSCLC cohort studied with whole-exome DNA sequencing. High levels of LAG-3 on T cells or elevated RQI heterogeneity index were associated with worse survival in the cohort., Conclusion: Baseline T cell density and T cell exhaustion marker expression can stratify outcomes in PD-L1 positive patients with NSCLC treated with ICI. Spatial immune heterogeneity can be measured using the RQI and is associated with survival in NSCLC., Competing Interests: Competing interests: JG has served as a compensated consultant or received honoraria from Bristol Myers Squibb, Takeda, Loxo/Lilly, Blueprint, Oncorus, Regeneron, Gilead, Moderna, AstraZeneca, EMD Serono, Pfizer, Novartis, Merck, and GlydeBio; research support from Novartis; institutional research support from Bristol Myers Squibb, Tesaro, Moderna, Blueprint, Jounce, Array Biopharma, Merck, Adaptimmune, Novartis, and Alexo; and has an immediate family member who is an employee with equity at Ironwood Pharmaceuticals.

Background: Alectinib, a second-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI), is highly effective in advanced ALK-rearranged non-small-cell lung cancer and represents a standard first-line therapy. New strategies are needed, however, to delay resistance. We conducted a phase I/II study to assess the safety and efficacy of combining alectinib with bevacizumab, a monoclonal antibody against vascular endothelial growth factor., Patients and Methods: Patients with advanced ALK-rearranged non-squamous non-small-cell lung cancer were enrolled. The phase I portion employed a dose de-escalation strategy with alectinib and bevacizumab starting at the individual standard doses. The primary objective was to determine the recommended phase II dose (RP2D). In phase II, the primary objective was to evaluate the safety of the combination at the RP2D; the secondary objective was to determine extracranial and intracranial efficacy., Results: Eleven patients were enrolled between September 2015 and February 2020. Most patients (82%) had baseline brain metastases. Six patients (55%) were treatment-naive; five (46%) had received prior ALK TKIs (crizotinib, n = 3; ceritinib, n = 1; crizotinib then brigatinib, n = 1). No dose-limiting toxicities occurred. RP2D was determined as alectinib 600 mg orally twice daily plus bevacizumab 15 mg/kg intravenously every 3 weeks. Three patients experienced grade 3 treatment-related adverse events: pneumonitis related to alectinib, proteinuria related to bevacizumab, and hypertension related to bevacizumab. Treatment-related intracranial hemorrhage was not observed. Six (100%) of six treatment-naive patients and three (60%) of five ALK TKI-pretreated patients had objective responses; median progression-free survival was not reached (95% confidence interval, 9.0 months-not reached) and 9.5 months (95% confidence interval, 4.3 months-not reached), respectively. Intracranial responses occurred in four (100%) of four treatment-naive and three (60%) of five TKI-pretreated patients with baseline brain metastases. The study was stopped prematurely because of slow accrual., Conclusions: Alectinib plus bevacizumab was well tolerated without unanticipated toxicities or dose-limiting toxicities., Competing Interests: Disclosure JJL has served as a compensated consultant for Genentech, C4 Therapeutics, Blueprint Medicines, Nuvalent, Bayer, Novartis, and Turning Point Therapeutics; received honorarium and travel support from Pfizer; received institutional research funds from Roche/Genentech, Hengrui Therapeutics, Turning Point Therapeutics, Neon Therapeutics, Relay Therapeutics, Bayer, Elevation Oncology, Linnaeus Therapeutics, and Novartis; received CME funding from OncLive, MedStar Health, and Northwell Health.

Background: ADP-A2M10 specific peptide enhanced affinity receptor (SPEAR) T cells (ADP-A2M10) are genetically engineered autologous T cells that express a high-affinity melanoma-associated antigen A10 (MAGE-A10)-specific T-cell receptor (TCR) targeting MAGE-A10 + tumors in the context of human leukocyte antigen (HLA)-A*02. ADP-0022-003 was a phase I dose-escalation trial that aimed to evaluate the safety and antitumor activity of ADP-A2M10 in non-small cell lung cancer (NSCLC) (NCT02592577)., Methods: Eligible patients were HLA-A*02 positive with advanced NSCLC expressing MAGE-A10. Patients underwent apheresis; T cells were isolated, transduced with a lentiviral vector containing the TCR targeting MAGE-A10, and expanded. Patients underwent lymphodepletion with varying doses/schedules of fludarabine and cyclophosphamide prior to receiving ADP-A2M10. ADP-A2M10 were administered at 0.08-0.12×10 9 (dose group 1), 0.5-1.2×10 9 (dose group 2), and 1.2-15×10 9 (dose group 3/expansion) transduced cells., Results: Eleven patients (male, n=6; female, n=5) with NSCLC (adenocarcinoma, n=8; squamous cell carcinoma, n=3) were treated. Five, three, and three patients received cells in dose group 1, dose group 2, and dose group 3/expansion, respectively. The most frequently reported grade ≥3 adverse events were lymphopenia (n=11), leukopenia (n=10), neutropenia (n=8), anemia (n=6), thrombocytopenia (n=5), and hyponatremia (n=5). Three patients presented with cytokine release syndrome (grades 1, 2, and 4, respectively). One patient received the highest dose of lymphodepletion (fludarabine 30 mg/m 2 on days -5 to -2 and cyclophosphamide 1800 mg/m 2 on days -5 to -4) prior to a second infusion of ADP-A2M10 and had a partial response, subsequently complicated by aplastic anemia and death. Responses included: partial response (after second infusion; one patient), stable disease (four patients), clinical or radiographic progressive disease (five patients), and not evaluable (one patient). ADP-A2M10 were detectable in peripheral blood and in tumor tissue. Peak persistence was higher in patients who received higher doses of ADP-A2M10., Conclusions: ADP-A2M10 demonstrated an acceptable safety profile and no evidence of toxicity related to off-target binding or alloreactivity. There was persistence of ADP-A2M10 in peripheral blood as well as ADP-A2M10 trafficking into the tumor. Given the discovery that MAGE-A10 and MAGE-A4 expression frequently overlap, this clinical program closed as trials with SPEAR T cells targeting MAGE-A4 are ongoing., Competing Interests: Competing interests: AG holds stock options in Adaptimmune.
