Glecirasib in KRAS-mutated nonsmall-cell lung cancer: a phase 2b trial.

Glecirasib (JAB-21822) is a new covalent oral KRAS-G12C inhibitor. This multicenter, single-arm phase 2b study assessed the efficacy and safety of glecirasib administered orally at 800 mg daily in patients with locally advanced or metastatic KRAS-mutated nonsmall-cell lung cancer. The primary endpoint was the objective response rate (ORR) assessed by an independent review committee (IRC).

Real-world studies of crizotinib in patients with ROS1-positive non-small-cell lung cancer: experience from China.

The treatment of non-small-cell lung cancer (NSCLC) has progressed from histology-oriented cytotoxic therapy to the era of molecular biology-oriented targeted therapy and immunotherapy. As the first tyrosine kinase inhibitor (TKI) targeting the pathway, crizotinib is widely used as a first-line regimen for -rearranged NSCLC. However, due to the paucity of solid data from randomized, controlled phase III clinical studies, clinicians often require more systematic, real-world data-based guidance for its optimal clinical use.

First-line treatments for KRAS-mutant non-small cell lung cancer: current state and future perspectives.

mutations are common in non-small cell lung cancer (NSCLC) and are associated with patient prognosis; however, targeting has faced various difficulties. Currently, immunotherapy, chemotherapy, and chemoimmunotherapy play pivotal roles in the first-line treatment of -mutated NSCLC. Here, we summarize the current evidence on first-line therapies and compare the treatment outcomes and biomarkers for different regimens.

Lower respiratory tract microbiome is associated with checkpoint inhibitor pneumonitis in lung cancer patients.

Background: The gut microbiome is associated with the occurrence and severity of immune-related adverse events (irAEs) in cancer patients undergoing immunotherapy. However, the relationship between the lower respiratory tract (LRT) microbiome and checkpoint inhibitor pneumonitis (CIP) in lung cancer patients who underwent immunotherapy is unclear. The aim of the present study was to investigate the associations between the LRT microbiome and CIP in lung cancer patients receiving immunotherapy.

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.

Clinicopathological Characteristics of Inflammatory Myofibroblastic Tumor: A Single Center Retrospective Cohort Study.

Background: Inflammatory myofibroblastic tumor (IMT) is a rare intermediate-grade neoplasm. It presents a great challenge in diagnosis and treatment. This study aims to identify the clinicopathological characteristics of IMT.

Tocilizumab for Advanced Non-Small-Cell Lung Cancer With Concomitant Cachexia: An Observational Study.

Background: Cancer cachexia significantly contributes to morbidity and mortality in patients with non-small-cell lung cancer (NSCLC). Inflammatory pathways mediated by interleukin-6 (IL-6) play a crucial role in the development of cancer cachexia. This study aimed to investigate the use of tocilizumab in the management of NSCLC with coexisting IL-6-elevated cachexia.

Gut microbiome metabolites, molecular mimicry, and species-level variation drive long-term efficacy and adverse event outcomes in lung cancer survivors.

Background: The influence of the gut microbiota on long-term immune checkpoint inhibitor (ICI) efficacy and immune-related adverse events (irAEs) is poorly understood, as are the underlying mechanisms.

Methods: We performed gut metagenome and metabolome sequencing of gut microbiotas from patients with lung cancer initially treated with anti-PD-1/PD-L1 therapy and explored the underlying mechanisms mediating long-term (median follow-up 1167 days) ICI responses and immune-related adverse events (irAEs). Results were validated in external, publicly-available datasets (Routy, Lee, and McCulloch cohorts).

Effectiveness and safety of azvudine versus nirmatrelvir-ritonavir in adult patients infected with COVID-19 omicron strains: a retrospective study in Beijing.

The study was to evaluate the clinical outcomes of azvudine versus nirmatrelvir-ritonavir against omicron strains of coronavirus disease 2019 infections and determine their comparative effectiveness. This retrospective study included 716 patients who received nirmatrelvir-ritonavir (NR group) or azvudine (FNC group) at Peking Union Medical College Hospital between 1 November 2022 and 27 February 2023. Patients in the FNC group (n = 304) were younger, exhibited less severe symptoms, started antiviral therapy later, received corticosteroids more frequently, and used tocilizumab less frequently than patients in the NR group (n = 412).

Bronchoalveolar lavage fluid analysis in patients with checkpoint inhibitor pneumonitis.

Background: Checkpoint inhibitor pneumonitis (CIP) is a relatively uncommon but potentially life-threatening immune-related adverse event (irAE). Lung biopsies have not been commonly performed for CIP patients. Bronchoalveolar lavage fluid (BALF) analysis is a useful diagnostic approach for interstitial lung disease.

Development and validation of a UPLC-MS/MS method for rapid and simultaneous quantification of BPI-460372 and its metabolites BPI-460444 and BPI-460456 in human plasma.

In cancer development and progression, the Hippo signaling pathway functions. The transcriptional enhanced associate domain (TEAD) stands out as a pivotal transcription factor within this pathway, and the suppression of TEAD represents a promising approach for cancer treatment. The primary aim of the study was to establish an analytical method for the concurrent quantification of a novel TEAD target inhibitor, BPI-460372, and its principal metabolites, BPI-460444 and BPI-460456, in human plasma.

Clinical manifestation and outcome of lung cancer patients with ocular metastasis: 16 case reports and systematic review.

Ocular metastasis is a rare type of distant metastasis of lung cancer. Limited information is available regarding ocular symptoms, diagnosis, treatment, and prognosis. We reported 16 patients diagnosed with ocular metastasis from lung cancer treated at our hospital from January 1988 to March 2024 and conducted a systematic review of 100 patients retrieved from the PubMed database from January 2014 to December 2023.

Enhancement of sweetpotato tolerance to chromium stress through melatonin and glutathione: Insights into photosynthetic efficiency, oxidative defense, and growth parameters.

Melatonin (MT) and reduced glutathione (GSH) roles in mitigating chromium (Cr) toxicity in sweetpotato were explored. Plants, pre-treated with varying MT and GSH doses, were exposed to Cr (40 μM). Cr severely hampered growth by disrupting leaf photosynthesis, root system, and oxidative processes and increased Cr absorption.

Efficacy and safety of azvudine in symptomatic adult COVID-19 participants who are at increased risk of progressing to critical illness: a study protocol for a multicentre randomized double-blind placebo-controlled phase III trial.

Background: Severe acute respiratory syndrome coronavirus 2 will coexist with humans for a long time, and it is therefore important to develop effective treatments for coronavirus disease 2019 (COVID-19). Recent studies have demonstrated that antiviral therapy is a key factor in preventing patients from progressing to severe disease, even death. Effective and affordable antiviral medications are essential for disease treatment and are urgently needed.

Nivolumab Plus Chemotherapy in Epidermal Growth Factor Receptor-Mutated Metastatic Non-Small-Cell Lung Cancer After Disease Progression on Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors: Final Results of CheckMate 722.

Purpose: The phase III CheckMate 722 trial (ClinicalTrials.gov identifier: NCT02864251) evaluated nivolumab plus chemotherapy versus chemotherapy in patients with epidermal growth factor receptor ()-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 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.
