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.

A simplified scoring system for predicting treatment response in limited-stage small-cell lung cancer (EAST score).

Aims: This study aimed at developing a scoring system (EAST score) to predict recurrence after chemoradiotherapy in limited-stage small-cell lung cancer (LS-SCLC).

Patients & Methods: Treatment-naïve LS-SCLC patients receiving concurrent chemoradiotherapy (CCRT) ( = 234) or sequential chemoradiotherapy ( = 53) were retrospectively reviewed. Using data from CCRT population, clinical and radiological variables associated with disease progression were identified.

Observational study of the efficacy and safety of first-line osimertinib and later treatments for uncommon epidermal growth factor receptor-activating mutation-positive advanced non-small cell lung cancer.

Introduction: Osimertinib, a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, is a first-line therapy for advanced or metastatic non-small cell lung cancer (NSCLC) with EGFR mutations, including both sensitizing and T790M resistance mutations. Its real-world efficacy against uncommon EGFR mutations remains under-researched.

Methods: The REIWA study, a multicentric, prospective, observational study conducted in Japan from September 2018 to August 2020, enrolled patients with advanced or recurrent EGFR mutation-positive NSCLC receiving osimertinib.

Clinical outcomes of patients with EGFR-mutated NSCLC developing interstitial lung disease during first-line osimertinib therapy: a sub-analysis of the Reiwa study.

Introduction: Osimertinib-induced interstitial lung disease in untreated EGFR-mutated, advanced non-small cell lung cancer is being reported at a higher rate in Japan than elsewhere. However, data on the interstitial lung disease incidence during first-line osimertinib therapy and the course of lung cancer treatments administered after interstitial lung disease onset in the real-world setting are scarce.

Materials And Methods: The present study reviewed the data from the Reiwa study, a multicentric, observational study examining the efficacy and safety of first-line osimertinib therapy in the clinical setting.

Outcome of osimertinib-treated patients with epidermal growth factor receptor mutation-positive nonsmall cell lung cancer requiring dose reduction: a secondary analysis of the Reiwa study.

Background: Osimertinib is effective in patients with epidermal growth factor receptor (EGFR) mutation-positive nonsmall cell lung cancer (NSCLC). However, some patients require osimertinib dose reduction because of adverse events. This study assessed the characteristics of osimertinib dose reduction and compared the efficacies of reduced-dose and regular-dose osimertinib.
