Datopotamab Deruxtecan in Advanced or Metastatic Non-Small Cell Lung Cancer With Actionable Genomic Alterations: Results From the Phase II TROPION-Lung05 Study.

Purpose: Datopotamab deruxtecan (Dato-DXd) is a trophoblast cell-surface antigen-2-directed antibody-drug conjugate with a highly potent topoisomerase I inhibitor payload. The TROPION-Lung05 phase II trial (ClinicalTrials.gov identifier: NCT04484142) evaluated the safety and clinical activity of Dato-DXd in patients with advanced/metastatic non-small cell lung cancer (NSCLC) with actionable genomic alterations progressing on or after targeted therapy and platinum-based chemotherapy.

Sunvozertinib monotherapy in EGFR tyrosine kinase inhibitor-resistant non-small cell lung cancer with EGFR mutations.

Background: Multiple agents can be used to treat patients with EGFR mutated non-small cell lung cancer (NSCLC) who develop resistance to EGFR tyrosine kinase inhibitors (TKIs), but the clinical outcome was not satisfactory, especially in patients with multiple lines of prior therapies. Therefore, there is an unmet medical need for these patients. Sunvozertinib is an oral, potent, irreversible, and mutant-selective EGFR TKI targeting EGFR mutations with weak activity against wild-type EGFR.

β-d-Ribofuranose as a Core with a Phosphodiester Moiety as the Enzyme Recognition Site for Codrug Development.

An ideal codrug design should be able to control drug release, offer selectivity during drug delivery, and break down into non-toxic fragments after biodegradation. Our design incorporates d-ribofuranose as the core, with carbamate and carbonate groups as linking joints, a phosphodiester moiety as an enzyme recognition site, and lenalidomide and paclitaxel as the constituent drugs. The codrug synthesis involves seven steps with a 33% overall yield.

Registry of Genetic Alterations of Taiwan Non-Small Cell Lung Cancer by Comprehensive Next-Generation Sequencing: A Real-World Cohort Study-Taiwan Cooperative Oncology Group T1521.

Purpose: Tissue-based next-generation sequencing (NGS) analysis is highly recommended for patients with advanced/metastatic non-small cell lung cancer (NSCLC). We investigated a specific patient population with NSCLC that required tissue-based NGS analysis.

Materials And Methods: We enrolled 500 patients with advanced/metastatic (1) epidermal growth factor receptor () mutations or anaplastic large-cell lymphoma kinase () rearrangement-positive NSCLC who had failed at minimum one line of tyrosine kinase inhibitor (TKI) therapy, (2) -negative nonsquamous, and (3) non- or light-smoker patients with squamous NSCLC who were treatment-naïve or had failed at maximum two lines of systemic treatment.

Defective N-glycosylation of IL6 induces metastasis and tyrosine kinase inhibitor resistance in lung cancer.

The IL6-GP130-STAT3 pathway facilitates lung cancer progression and resistance to tyrosine kinase inhibitors. Although glycosylation alters the stability of GP130, its effect on the ligand IL6 remains unclear. We herein find that N-glycosylated IL6, especially at Asn73, primarily stimulates JAK-STAT3 signaling and prolongs STAT3 phosphorylation, whereas N-glycosylation-defective IL6 (deNG-IL6) induces shortened STAT3 activation and alters the downstream signaling preference for the SRC-YAP-SOX2 axis.

A rare case of an endobronchial mass due to Neurospora intermedia.

The ascomycete filamentous fungus Neurospora intermedia is commonly used in the food industry and considered nonpathogenic to humans. This study characterizes four N. intermedia isolates recovered from three patients.

Rab37 mediates trafficking and membrane presentation of PD-1 to sustain T cell exhaustion in lung cancer.

Background: Programmed cell death protein 1 (PD-1) is an immune checkpoint receptor expressed on the surface of T cells. High expression of PD-1 leads to T-cell dysfunction in the tumor microenvironment (TME). However, the mechanism of intracellular trafficking and plasma membrane presentation of PD-1 remains unclear.

Distinct Features of Plasma Ultrashort Single-Stranded Cell-Free DNA as Biomarkers for Lung Cancer Detection.

Background: Using broad range cell-free DNA sequencing (BRcfDNA-Seq), a nontargeted next-generation sequencing (NGS) methodology, we previously identified a novel class of approximately 50 nt ultrashort single-stranded cell-free DNA (uscfDNA) in plasma that is distinctly different from 167 bp mononucleosomal cell-free DNA (mncfDNA). We hypothesize that uscfDNA possesses characteristics that are useful for disease detection.

Methods: Using BRcfDNA-Seq, we examined both cfDNA populations in the plasma of 18 noncancer controls and 14 patients with late-stage nonsmall cell lung carcinoma (NSCLC).

Overall Survival with Osimertinib in Resected -Mutated NSCLC.

Background: Among patients with resected, epidermal growth factor receptor ()-mutated, stage IB to IIIA non-small-cell lung cancer (NSCLC), adjuvant osimertinib therapy, with or without previous adjuvant chemotherapy, resulted in significantly longer disease-free survival than placebo in the ADAURA trial. We report the results of the planned final analysis of overall survival.

Methods: In this phase 3, double-blind trial, we randomly assigned eligible patients in a 1:1 ratio to receive osimertinib (80 mg once daily) or placebo until disease recurrence was observed, the trial regimen was completed (3 years), or a discontinuation criterion was met.

Three-Year Safety, Tolerability, and Health-Related Quality of Life Outcomes of Adjuvant Osimertinib in Patients With Resected Stage IB to IIIA EGFR-Mutated NSCLC: Updated Analysis From the Phase 3 ADAURA Trial.

Introduction: In ADAURA, adjuvant osimertinib significantly improved disease-free survival versus placebo in resected stage IB to IIIA EGFR-mutated NSCLC. We report in-depth analyses of three-year safety, tolerability, and health-related quality of life (HRQoL) from ADAURA.

Methods: Patients were randomized 1:1 to osimertinib 80 mg or placebo once daily for up to 3 years.
