Brief Report: Preventing Infusion-related Reactions With Intravenous Amivantamab: Results From SKIPPirr, a Phase 2 Study.

Introduction: Amivantamab, an EGFR-MET bispecific antibody, is approved for multiple indications in EGFR-mutated advanced non-small cell lung cancer (NSCLC) as monotherapy or combined with other agents. Intravenous amivantamab is associated with a 67% infusion-related reactions (IRR) rate.

Methods: The phase 2 SKIPPirr study (NCT05663866) enrolled patients with EGFR-mutated (Ex19del/L858R) advanced NSCLC after progression on osimertinib and platinum-based chemotherapy who received intravenous amivantamab plus oral lazertinib (amivantamab-lazertinib), a third-generation tyrosine kinase inhibitor.

Detailed characterization of combination treatment with MET inhibitor plus EGFR inhibitor in -mutant and -amplified non-small cell lung cancer.

Background: Detailed clinical data about combination treatment with MET inhibitor (METi) and EGFR inhibitor (EGFRi) is lacking in patients with -mutant, -amplified, and EGFRi-resistant non-small cell lung cancer (NSCLC). This study aimed to report longitudinal data on the efficacy and safety of this combination treatment.

Methods: We retrospectively analyzed 44 patients with advanced -mutant and -amplified NSCLC who were treated with any types of METi plus EGFRi after progression with EGFRi at the National Cancer Center Hospital.

Capmatinib in MET exon 14-mutated non-small-cell lung cancer: final results from the open-label, phase 2 GEOMETRY mono-1 trial.

Background: Capmatinib has previously shown activity in treatment-naive and previously treated patients with non-small-cell lung cancer (NSCLC) and a MET exon 14-skipping mutation (METex14). Here, we report the final outcomes from the phase 2 GEOMETRY mono-1 study with an aim to provide further evidence for the activity of capmatinib.

Methods: In this non-randomised, multi-cohort, open-label, phase 2 trial conducted in 152 centres and hospitals in 25 countries, with patients treated in 95 centres in 20 countries, eligible patients (aged ≥18 years) with MET-dysregulated, EGFR wild-type, and ALK rearrangement-negative advanced NSCLC (stage IIIB/IV) and an Eastern Cooperative Oncology Group performance status of 0 or 1 were assigned to cohorts (1a, 1b, 2, 3, 4, 5a, 5b, 6 and 7) based on their MET status (METex14 or MET amplification) and previous therapy lines.

ctDNA Dynamics and Mechanisms of Acquired Resistance in Patients Treated with Osimertinib with or without Bevacizumab from the Randomized Phase II ETOP-BOOSTER Trial.

Purpose: The ETOP 10-16 BOOSTER study was a randomized phase II trial of osimertinib and bevacizumab therapy versus osimertinib therapy in patients with an acquired EGFR T790M mutation. The mechanisms of acquired resistance to osimertinib and bevacizumab have not been described previously.

Experimental Design: Next-generation sequencing (Guardant360) was conducted in serial plasma samples.

Longitudinal Analyses of Circulating Tumor DNA for the Detection of EGFR Mutation-Positive Advanced NSCLC Progression During Treatment: Data From FLAURA and AURA3.

Introduction: EGFR tyrosine kinase inhibitor (EGFR-TKI)-sensitizing and -resistance mutations may be detected in plasma through circulating tumor DNA (ctDNA). Circulating tumor DNA level changes reflect alterations in tumor burden and could be a dynamic indicator of treatment effect. This analysis aimed to determine whether longitudinal EGFR-mutation ctDNA testing could detect progressive disease (PD) before radiologic detection.

Seasonal influences on the efficacy of anti-programmed cell death (ligand) 1 inhibitors in lung cancer.

Background: Seasonal variations in systemic immunity have been reported. This study aimed to evaluate whether seasonality affects the efficacy of anticancer immunotherapy.

Methods: A total of 604 patients with lung cancer receiving single anti-programmed cell death (ligand) 1 (anti-PD-[L]1) inhibitors from two prospective observational cohorts were screened.

Prognostic Model for High-Grade Neuroendocrine Carcinoma of the Lung Incorporating Genomic Profiling and Poly (ADP-ribose) Polymerase-1 Expression.

Purpose: High-grade neuroendocrine carcinoma (HGNEC) of the lung is an aggressive cancer with a complex biology. We aimed to explore the prognostic value of genetic aberrations and poly(ADP-ribose) polymerase-1 (PARP1) expression in HGNEC and to establish a novel prognostic model.

Materials And Methods: We retrospectively enrolled 191 patients with histologically confirmed HGNEC of the lung.

Proteogenomic Characterization Reveals Estrogen Signaling as a Target for Never-Smoker Lung Adenocarcinoma Patients without EGFR or ALK Alterations.

Unlabelled: Never-smoker lung adenocarcinoma (NSLA) is prevalent in Asian populations, particularly in women. EGFR mutations and anaplastic lymphoma kinase (ALK) fusions are major genetic alterations observed in NSLA, and NSLA with these alterations have been well studied and can be treated with targeted therapies. To provide insights into the molecular profile of NSLA without EGFR and ALK alterations (NENA), we selected 141 NSLA tissues and performed proteogenomic characterization, including whole genome sequencing (WGS), transcriptomic, methylation EPIC array, total proteomic, and phosphoproteomic analyses.

Efficacy and safety of tepotinib in Asian patients with advanced NSCLC with MET exon 14 skipping enrolled in VISION.

Background: Tepotinib, a MET inhibitor approved for the treatment of MET exon 14 (METex14) skipping NSCLC, demonstrated durable clinical activity in VISION (Cohort A + C; N = 313): objective response rate (ORR) 51.4% (95% CI: 45.8, 57.

Drug Response of Patient-Derived Lung Cancer Cells Predicts Clinical Outcomes of Targeted Therapy.

Intratumor heterogeneity leads to different responses to targeted therapies, even within patients whose tumors harbor identical driver oncogenes. This study examined clinical outcomes according to a patient-derived cell (PDC)-based drug sensitivity test in lung cancer patients treated with targeted therapies. From 487 lung cancers, 397 PDCs were established with a success rate of 82%.

Infection-related Hospitalizations During Immune Checkpoint Inhibitor Treatment Without Immunosuppressants.

Immunosuppressants are increasingly being used in the clinic to manage immune-related adverse effects. Consequently, the incidence of secondary infections associated with immunosuppression is increasing. However, little is known about primary infections during immune checkpoint inhibitor (ICI) treatment without immunosuppressants.

Pan-Tumor Analytical Validation and Osimertinib Clinical Validation in EGFR Mutant Non-Small-Cell Lung Cancer, Supporting the First Next-Generation Sequencing Liquid Biopsy in Vitro Diagnostic.

Comprehensive genotyping is necessary to identify therapy options for patients with advanced cancer; however, many cancers are not tested, partly because of tissue limitations. Next-generation sequencing (NGS) liquid biopsies overcome some limitations, but clinical validity is not established and adoption is limited. Herein, clinical bridging studies used pretreatment plasma samples and data from FLAURA (NCT02296125; n = 441) and AURA3 (NCT02151981; n = 450) pivotal studies to demonstrate clinical validity of Guardant360 CDx (NGS LBx) to identify patients with advanced EGFR mutant non-small-cell lung cancer who may benefit from osimertinib.

Tepotinib in patients with non-small cell lung cancer with high-level MET amplification detected by liquid biopsy: VISION Cohort B.

High-level MET amplification (METamp) is a primary driver in ∼1%-2% of non-small cell lung cancers (NSCLCs). Cohort B of the phase 2 VISION trial evaluates tepotinib, an oral MET inhibitor, in patients with advanced NSCLC with high-level METamp who were enrolled by liquid biopsy. While the study was halted before the enrollment of the planned 60 patients, the results of 24 enrolled patients are presented here.

TARGET: A Phase II, Open-Label, Single-Arm Study of 5-Year Adjuvant Osimertinib in Completely Resected EGFR-Mutated Stage II to IIIB NSCLC Post Complete Surgical Resection.

Introduction: Osimertinib is a central nervous system (CNS)-active, third generation, irreversible, epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that potently and selectively inhibits EGFR-TKI sensitizing and EGFR T790M resistance mutations, with demonstrated efficacy in EGFR-mutated (EGFRm) non-small cell lung cancer (NSCLC). We present the rationale and design for TARGET (NCT05526755), which will evaluate the efficacy and safety of 5 years of adjuvant osimertinib in patients with completely resected EGFRm stage II to IIIB NSCLC.

Materials And Methods: TARGET is a phase II, multinational, open-label, single-arm study.

Nivolumab after Induction Chemotherapy in Previously Treated Non-Small-Cell Lung Cancer Patients with Low PD-L1 Expression.

This study aimed to investigate whether cyclophosphamide (C) and adriamycin (A) induction therapy (IT) prior to nivolumab could enhance the efficacy of nivolumab in previously treated patients with non-squamous (NSQ) non-small-cell lung cancer (NSCLC) with less than 10% programmed death-ligand 1 (PD-L1) expression. Twenty-two enrolled patients received four cycles of CA-IT every 3 weeks. Nivolumab was given 360 mg every 3 weeks from the second cycle and 480 mg every 4 weeks after four cycles of CA-IT.
