KRAS G12

Garsorasib demonstrated encouraging antitumor activity and a tolerable safety profile in patients with KRAS G12C-mutated advanced pancreatic cancer.

Glecirasib monotherapy and its combination with cetuximab represent potential treatment options for patients with advanced, refractory colorectal cancer harbouring KRASG12C mutations. The promising efficacy and safety support further exploration of glecirasib-based combinations in earlier lines of treatment.

Molecular dynamics and NMR titration confirm the superior stability and binding affinity of the 10-mer. These results highlight how peptide length and conformation critically shape immune visibility, offering mechanistic insight for optimizing TCR-T therapies against elusive neoantigens like KRAS G12D.

Consistently, expression of IL-15 resulted in blockade of tumor progression in the TKP CCA model. These findings highlight the importance of oncogenic Kras in CCA tumor maintenance and underscore KRAS inhibition as a potential therapeutic approach for CCA.

This pooled analysis confirmed the robust efficacy and manageable safety of garsorasib in KRAS G12C-mutated NSCLC.

Glecirasib combined with sitneprotafib showed promising efficacy and manageable safety in patients with advanced KRASG12C -mutated NSCLC, particularly among those who had not received previous treatment. These findings support the evaluation of this combination in a phase 3 trial comparing this chemotherapy-free regimen to current standard of care in this patient group.

This is the first report of trametinib-nintedanib for a 57-year-old KRAS G12D-mutated recurrent pancreatic ductal adenocarcinoma. He had transient remission (lower CA19-9, stable lesions) but died of gastrointestinal bleeding, showing efficacy and bleeding risk.

Despite the historical challenges in targeting KRAS-mutant proteins, the findings of this study support the potential of natural products as scaffolds for anticancer drug discovery as a source for developing novel anticancer therapies. The identified phytochemicals from C. officinalis such as calendasaponin D and procyanidin A2 may serve as potential leads for future preclinical and experimental validation against KRAS-driven malignancies.

Olomorasib + pembrolizumab demonstrated manageable safety and promising antitumor activity in patients with KRAS G12C-mutant advanced NSCLC across PD-L1 expression levels, especially in the high PD-L1 first-line setting.

USP15 acts as a critical mediator of oncogenic KRAS-driven metabolic reprogramming in NSCLC by promoting glycolysis via the TGF-β/SMAD signaling cascade. These findings uncover a previously unrecognized role of USP15 in linking metabolic regulation to tumorigenic signaling in KRAS-mutant NSCLC and suggest that targeting USP15 may represent a promising therapeutic strategy for this aggressive cancer subtype.

Lipid-laden stellate cells promote fibrosis, immunosuppression, and epithelial-mesenchymal transition. NAFPD may represent an early, modifiable PDAC niche, warranting further imaging-omic studies and targeted prevention trials.

Immunophenotyping demonstrated TTF-1 nuclear positivity in the metastatic tumor alongside a classic colorectal profile: cytokeratin 7 (CK7) negativity, cytokeratin 20 (CK20) positivity, strong caudal-type homeobox transcription factor 2 (CDX2) and special AT-rich sequence-binding protein 2 (SATB2) nuclear expression, and absence of Napsin A. The patient underwent surgical resection of the primary sigmoid colon tumor and received 16 cycles of capecitabine plus bevacizumab chemotherapy. We discuss how the comprehensive immunohistochemical panel and genetic findings confirmed the colorectal origin of the lung lesions, emphasizing that combined marker profiles (TTF-1 +/CK7 -/CK20 +/CDX2 +/SATB2 +/Napsin A -) are more consistent with metastatic colorectal adenocarcinoma rather than an enteric-type adenocarcinoma of the lung, primary. The report reviews relevant literature and underscores the importance of correlating clinical history with pathology to avoid misdiagnosis.
