NCT07122882
Currently, tyrosine kinase inhibitor (TKI) remains the standard of care for oncogene-driven non-small cell lung cancer (NSCLC). However, almost all oncogene-driven NSCLCs would develop acquired resistance against TKI in clinical practice. Therefore, understanding the molecular mechanisms underlying the acquired resistance is a critical issue in lung cancer. Based on the literature, acquired resistance mechanism against EGFR TKI includes EGFR secondary mutation (T790M, C797X, L792X, G796X, L718Q, and exon 20 insertions), MET amplification, HER2 amplification, acquired gene fusions, and other complex alterations. From the perspective of mutagenesis, the acquired resistance against TKI may be associated with APOBEC mutational processes, kataegis, chromothripsis, extrachromosomal DNA (ecDNA), and the interaction among them. However, still 30% to 50% of oncogene-driven NSCLCs had no identified mechanism attributed to the acquired resistance. Previous studies mostly used targeted-gene sequencing, which may overlook some structural variation and the transcriptomic dynamics. This study aims to investigate the genomic alterations, mutational processes, and the transcriptomic landscape underlying the acquired resistance using integrated genomics.
NCT07396467
This retrospective observational study evaluates immune checkpoint inhibitor (ICI)-related outcomes in lung cancer patients with concomitant pulmonary fibrosis/interstitial lung disease (ILD) and determines how fibrosis/ILD modifies immunotherapy effectiveness and safety. The study characterizes the clinical, radiographic, pathological, and molecular features of lung cancer with ILD and examines their associations with ICI response and survival. A comparator cohort of lung cancer patients without radiographic ILD from the same institution and time period is included to compare ICI effectiveness (e.g., response and survival outcomes) and pulmonary toxicity signals, including pneumonitis and acute ILD exacerbation. In a translational sub-study, archived lung tumor specimens undergo single-cell and spatial transcriptomic profiling to identify fibrosis-associated tumor-microenvironment programs that may underlie differential immunotherapy outcomes.
