ADRIATIC: When face value is enough.

The ADRIATIC study marks a major advancement in limited-stage small cell lung cancer (LS-SCLC), showing that consolidation therapy with durvalumab after chemoradiation significantly improves overall survival (OS) and progression-free survival (PFS). This establishes durvalumab as the new standard of care for LS-SCLC.

Use of Oncogene Overlap by Tissue-Based Next-Generation Sequencing to Explore the Mutational Landscape and Survival Impact of HER2, KRAS and MET Copy-Number Gain in Nonsmall Cell Lung Cancer.

Background: Gene copy number gain (CNG) is a continuous variable. The relevant cutpoint for HER2, KRAS and MET CNG in non-mall cell lung cancer remains uncertain. As de novo driver oncogenes are largely mutually exclusive, oncogene overlap analysis can be used to explore CNG thresholds.

NRG1 Fusions in NSCLC: Being eNRGy Conscious.

Fusions in neuregulin 1 () are rare oncogenic drivers that occur across a number of tumor types, including non-small cell lung cancer (NSCLC). has an EGF-like domain that serves as a ligand for HER3 receptors, inducing heterodimerization, usually with HER2, and subsequent activation of oncogenic downstream signaling pathways. Emerging evidence suggests that NSCLC harboring fusions do not respond as well to standard therapeutic options including chemotherapy and immunotherapy, and prognosis is poor.

Real-World Outcomes of First-Line Treatment With Anti-PD(L)1-Based Combination Therapy for Nonsquamous Metastatic Non-Small Cell Lung Cancer: A Multiregional Chart Review in Europe, Japan, and the United States.

Purpose: Anti-PD-1/PD(L)1-based combination therapy is the standard of care in first line (1L) for metastatic nonsquamous non-small cell lung cancer (mnsqNSCLC) without driver alterations. This study aimed to evaluate real-world clinical outcomes in this population.

Methods: Eligible physicians in the United States, Europe, and Japan abstracted information from medical charts of eligible adult patients with mnsqNSCLC (without /, no known alterations) who initiated 1L anti-PD(L)1-based combination therapy for mnsqNSCLC between 2017 and 2021.

Molecular profiling METex14+ non-small cell lung cancer (NSCLC): Impact of histology.

Objectives: MET exon 14 skipping alterations (METex14+) represent a heterogeneous subgroup of non-small cell lung cancer (NSCLC) with distinct biological and genomic features. We characterized this heterogeneity in a large cohort, integrating genomic and transcriptomic profiling with clinical outcomes, to elucidate the histologic and molecular traits and survival patterns of METex14+ NSCLC.

Materials And Methods: NSCLC tissue samples (n = 28,739) underwent DNA-based next-generation sequencing (592 genes, NextSeq) or whole-exome sequencing (NovaSeq), RNA-sequencing including whole transcriptome sequencing (WTS, NovaSeq), and PD-L1 IHC (Dako 22C3) at Caris Life Sciences.

A First-in-Human Study of cinrebafusp alfa, a HER2/4-1BB Bispecific Molecule, in Patients with HER2-Positive Advanced Solid Malignancies.

Purpose: 4-1BB (CD137) is a costimulatory immune receptor expressed on activated T cells, activated B cells, natural killer cells and tumor-infiltrating lymphocytes, making it a promising target for cancer immunotherapy. Cinrebafusp alfa, a monoclonal antibody-like bispecific protein targeting HER2 and 4-1BB, aims to localize 4-1BB activation to HER2-positive tumors. This study evaluated the safety, tolerability, and preliminary efficacy of cinrebafusp alfa in patients with previously treated HER2-positive malignancies.

Real-world treatment sequencing and effectiveness of second- and third-generation ALK tyrosine kinase inhibitors for ALK-positive advanced non-small cell lung cancer.

Introduction: With multiple targeted therapies approved for anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC), it is increasingly important to understand outcomes with various sequences of next-generation ALK tyrosine kinase inhibitors (TKIs). We describe contemporary sequencing patterns and treatment effectiveness of first-line (1L) and second-line (2L) treatments in patients who received second-generation ALK TKIs in the 1L treatment of ALK-positive NSCLC in the United States.

Methods: A cohort of adults with ALK-positive advanced NSCLC who initiated treatment with 1L alectinib or brigatinib between June 2017 and April 2021 in the Flatiron Health electronic health record-derived de-identified database were followed through April 2023.

Characteristics of Long-Term Survivors With EGFR-Mutant Metastatic NSCLC.

Introduction: Characteristics of long-term survivors in EGFR-mutant (EGFRm) NSCLC are not fully understood. This retrospective analysis evaluated a multi-institution cohort of patients with EGFRm NSCLC treated in the pre-osimertinib era and sought to describe characteristics of long-term survivors.

Methods: Clinical characteristics and outcomes were abstracted from the electronic medical records of patients with EGFRm metastatic NSCLC who started first-line therapy before 2015.

Genomic, immunologic, and prognostic associations of TROP2 (TACSTD2) expression in solid tumors.

Background: TROP2 (TACSTD2) expression is associated with decreased overall survival (OS) in some solid tumors, and the TROP2-targeting antibody-drug conjugate (ADC) sacituzumab govitecan has been approved in breast and urothelial carcinomas. We aimed to explore the multi-omic landscape associated with TACSTD2 gene expression in various solid tumors to identify patients most likely to benefit from this approach.

Methods: Breast (N = 11 246), colorectal (N = 15 425), hepatocellular (N = 433), pancreatic (N = 5488), and urothelial (N = 4125) tumors were stratified into quartiles by TACSTD2 gene expression, analyzed by next-generation DNA sequencing, whole transcriptome sequencing, and immunohistochemistry at Caris Life Sciences (Phoenix, AZ).

Tissue-specific thresholds of mutation burden associated with anti-PD-1/L1 therapy benefit and prognosis in microsatellite-stable cancers.

Immune checkpoint inhibitors (ICIs) targeting programmed cell death protein 1 or its ligand (PD-1/L1) have expanded the treatment landscape against cancers but are effective in only a subset of patients. Tumor mutation burden (TMB) is postulated to be a generic determinant of ICI-dependent tumor rejection. Here we describe the association between TMB and survival outcomes among microsatellite-stable cancers in a real-world clinicogenomic cohort consisting of 70,698 patients distributed across 27 histologies.

Real-World Treatment Patterns and Clinical Outcomes After Platinum-Doublet Chemotherapy and Immunotherapy in Metastatic Non-Small Cell Lung Cancer: A Multiregional Chart Review in the United States, Europe, and Japan.

Purpose: To characterize treatment patterns and real-world clinical outcomes of patients with metastatic non-small cell lung cancer (mNSCLC) who developed progression on an anti-PD-1/anti-PD-L1, herein referred to as anti-PD-(L)1, and platinum-doublet chemotherapy.

Methods: Eligible oncologists/pulmonologists in the United States, Europe (France, Germany, and United Kingdom), and Japan completed electronic case report forms for patients with mNSCLC (no evidence of alterations). Eligible patients had disease progression on/after an anti-PD-(L)1 and platinum-doublet chemotherapy (received concurrently or sequentially), initiated a subsequent line of therapy (LOT) between 2017 and 2021, and had an Eastern Cooperative Oncology Group (ECOG) performance status 0-2 at this subsequent LOT initiation (index date).

Immune heterogeneity in small-cell lung cancer and vulnerability to immune checkpoint blockade.

Atezolizumab (anti-PD-L1), combined with carboplatin and etoposide (CE), is now a standard of care for extensive-stage small-cell lung cancer (ES-SCLC). A clearer understanding of therapeutically relevant SCLC subsets could identify rational combination strategies and improve outcomes. We conduct transcriptomic analyses and non-negative matrix factorization on 271 pre-treatment patient tumor samples from IMpower133 and identify four subsets with general concordance to previously reported SCLC subtypes (SCLC-A, -N, -P, and -I).

The phase I/II eNRGy trial: Zenocutuzumab in patients with cancers harboring gene fusions.

Neuregulin 1 () fusions are oncogenic drivers that have been detected in non-small-cell lung cancer (NSCLC), pancreatic ductal adenocarcinoma (PDAC) and other solid tumors. fusions are rare, occurring in less than 1% of solid tumors. Patients with fusion positive (NRG1+) cancer have limited therapeutic options.

Influence of Comutation on the Tumor Immune Microenvironment and Clinical Outcomes With Immune Checkpoint Inhibitors in -Mutant Non-Small-Cell Lung Cancer.

Purpose: Non-small-cell lung cancer (NSCLC) with has inferior outcomes to immune checkpoint inhibitors (ICIs). Using multiomics, we evaluated whether a subtype of NSCLC with a uniquely inflamed tumor immune microenvironment (TIME) harboring comutations could have favorable outcomes to ICIs.

Patients And Methods: NSCLC tumors (N = 16,896) were analyzed by next-generation sequencing (DNA-Seq/592 genes).

Long-Term Survival and Stable Disease in a Patient with Extensive-Stage Small-Cell Lung Cancer after Treatment with Carboplatin, Etoposide and Atezolizumab.

Survival beyond 2 years is rare in patients with extensive-stage small-cell lung cancer (ES-SCLC) treated with chemotherapy alone. We describe a patient with ES-SCLC who was treated with carboplatin, etoposide and the programmed death-ligand 1 inhibitor atezolizumab in the IMpower133 study (ClinicalTrials.gov registration: NCT02763579) and who achieved exceptionally long-term survival.

Real-world outcomes associated with afatinib use in patients with solid tumors harboring NRG1 gene fusions.

Objectives: Neuregulin-1 (NRG1) fusions may drive oncogenesis via constitutive activation of ErbB signaling. Hence, NRG1 fusion-driven tumors may be susceptible to ErbB-targeted therapy. Afatinib (irreversible pan-ErbB inhibitor) has demonstrated activity in individual patients with NRG1 fusion-positive solid tumors.

Disparities in outcomes between Black and White patients in North America with thoracic malignancies and COVID-19 infection (TERAVOLT).

Background: Patients with thoracic malignancies who develop COVID-19 infection have a higher hospitalization rate compared to the general population and to those with other cancer types, but how this outcome differs by race and ethnicity is relatively understudied.

Methods: The TERAVOLT database is an international, multi-center repository of cross-sectional and longitudinal data studying the impact of COVID-19 on individuals with thoracic malignancies. Patients from North America with thoracic malignancies and confirmed COVID-19 infection were included for this analysis of racial and ethnic disparities.

SKYSCRAPER-02: Tiragolumab in Combination With Atezolizumab Plus Chemotherapy in Untreated Extensive-Stage Small-Cell Lung Cancer.

Purpose: The phase III SKYSCRAPER-02 study determined whether the benefits of atezolizumab plus carboplatin and etoposide (CE) could be enhanced by the addition of tiragolumab in untreated extensive-stage small-cell lung cancer (ES-SCLC). We report final progression-free survival (PFS) and overall survival (OS) analyses.

Methods: Patients received tiragolumab 600 mg/placebo, plus atezolizumab 1,200 mg and CE (four cycles), then maintenance tiragolumab/placebo plus atezolizumab.
