KRAS G13

The patient received first-line and maintenance therapy comprising carboplatin/pemetrexed, camrelizumab, and Endostar/bevacizumab...Our findings suggest that the combination of chemotherapy, immunotherapy, and anti-angiogenic agents may represent a viable therapeutic strategy for patients with KRAS G13C/TP53 co-mutated NSCLC. This case report suggests a potentially promising therapeutic strategy to improve long-term survival in this difficult-to-treat patient population.

The pan-RAS mRNA vaccine demonstrates structural stability and strong immunogenic potential for PDAC. Synergistic immune activation with R848 may enhance anti-tumor efficacy, warranting experimental validation and toxicity assessment for clinical translation.

This patent provides novel macrocycle compounds that inhibit key mutants (G12D/G13D) of the KRAS oncogene, which is the most frequently mutated in human cancers. These compounds, along with their pharmaceutical compositions and protein complexes, are intended for the treatment of cancers driven by these mutations.

We conclude that ddPCR testing of plasma supernatant achieved high overall agreement with tumour KRASmt status. There was varying abundance of KRAS detected in the plasma fractions.

Across a CRC panel that included SNU-C5/WT and its 5-fluorouracil- and oxaliplatin-resistant derivatives, HT-29 (KRAS-wild-type), and HCT-8 and LoVo (KRAS-mutant), co-immunoprecipitation showed that PrPC forms complexes with the 37/67 kDa laminin receptor (RPSA), with PrPC-RPSA association particularly increased in KRAS-mutant HCT-8 and LoVo cells. Taken together, these findings suggest that extracellular PrPC supports RAS-AKT signaling, proliferation, and tumor-associated angiogenesis in KRAS-mutant colorectal cancer, and that PrPC neutralization additively enhances 5-fluorouracil activity in KRAS-mutant models. The data provide a preclinical basis for evaluating PrPC antibodies in combination with fluoropyrimidine-based regimens in patients with KRAS-mutant CRC.

In this phase I study, we test a pooled synthetic long peptide vaccine targeting the six KRAS mutations (G12V, G12A, G12R, G12C, G12D, G13D) with ipilimumab and nivolumab in resected pancreatic adenocarcinoma. The vaccine also generates cross-reactive T cells that recognize more than one mutant KRAS antigen. These findings support the safety and diverse anti-tumor immunity of mutant KRAS vaccines (NCT04117087).

The cancer was refractory to regimens extrapolated from rectal cancer management (capecitabine with oxaliplatin, and irinotecan). Pelvic recurrence and osseous metastases were clearly radiosensitive. Tumor molecular profile showed microsatellite stable cancer with KRAS p.G13D and TP53 p.C176W mutations.
