AbstractPurpose: Non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion (Exon20ins) mutations exhibits inherent resistance to approved tyrosine kinase inhibitors. Amivantamab, an EGFR-MET bispecific antibody with…

AbstractBackground: Patients with EGFR-mutated non-small-cell lung cancer (NSCLC) given EGFR tyrosine kinase inhibitors (TKIs) inevitably become resistant to first-generation or second-generation drugs. We assessed the safety, tolerability, pharmacokineti…

AbstractBackground: Quavonlimab (MK-1308), a novel anti-CTLA-4 antibody, in combination with pembrolizumab was investigated in a phase I study.Patients and methods: Dose-escalation (DE) phase: patients with advanced/metastatic solid tumors received a…

AbstractEGFR exon 20 insertion driver mutations (Exon20ins) in non-small cell lung cancer (NSCLC) are insensitive to EGFR tyrosine kinase inhibitors (TKI). Amivantamab (JNJ-61186372), a bispecific antibody targeting EGFR-MET, has shown preclinical activit…

AbstractPurpose ROS1 rearrangement is a distinct molecular subset of non-small-cell lung cancer (NSCLC). We investigated the efficacy and safety of ceritinib in patients with ROS1-rearranged NSCLC. Patients and Methods We enrolled 32 patients with advanced NSC…

AbstractPurpose: To investigate the frequency and the prognostic role of fibroblast growth factor receptor 1 (FGFR1) amplification in patients with surgically resected squamous cell carcinoma of the lung (SCCL) and the association between smoking and FGFR…

AbstractImportance: Checkpoint inhibitors targeting programmed cell death 1 or its ligand (PD-L1) as monotherapies or in combination with anti-cytotoxic T-lymphocyte-associated antigen 4 have shown clinical activity in patients with metastatic non-small c…

AbstractIntroduction: Here we report efficacy and safety data of an Asian subset of the phase III FLAURA trial (NCT02296125), which compares osimertinib with standard of care (SoC) EGFR tyrosine kinase inhibitors (TKIs) in patients with previously untreat…

AbstractBackground: Targeted inhibition of the PD-L1-PD-1 pathway might be further amplified through combination of PD-1 or PD-L1 inhibitors with novel anti-TIGIT inhibitory immune checkpoint agents, such as tiragolumab. In the CITYSCAPE trial, we aimed t…

Abstract Background: We conducted co-clinical trials in patient-derived xenograft (PDX) models to identify predictive biomarkers for the multikinase inhibitor dovitinib in lung squamous cell carcinoma (LSCC).Methods: The PDX01-02 were establishe…
