Development of bifunctional CRBN-SOS1 degraders for treatment of mutant KRAS cancers. (On Demand | Hall A; Poster Bd # 349) - Apr 26, 2023 - Abstract #ASCO2023ASCO_1851; Strong synergistic antiproliferative effects were observed when SOS1 degraders were co-treated with KRAS inhibitors AMG510 (G12C) and MRTX1133 (G12D) in respective KRAS-mutant cell lines as well as with MEK inhibition and EGFR inhibition. Together, these results highlight the potential of SOS1 degraders alone and in combination as therapeutic options for a variety of KRAS-driven cancers.

Impact of novel pan-RAS inhibitors on efficacy and resistance to AMG-510 and MRTX-1133 in pancreatic cancer cell lines. (Available On Demand; Poster Bd # 476) - Apr 26, 2023 - Abstract #ASCO2023ASCO_1281; Recently, several mutant KRAS-targeted therapies (sotorasib and adagrasib) have been developed and show promise in PDAC patients. We have developed a series of novel RAS inhibitors that directly bind preferentially to mutant KRAS that may serve as new mutant KRAS-targeted therapeutics, and that may also have the potential to enhance the efficacy or suppress the resistance of AMG-510 and MRTX-1133.

The first inhibitor, BI-1701963, is in clinical studies alone or in combination with a KRAS inhibitor, a MAPK inhibitor or chemotherapeutics...This PROTAC exhibited the highest SOS1-directed activity due to target destruction, recycling and removal of SOS1 as a scaffolding protein. Although other first PROTACs have entered clinical trials, each conjugate must be meticulously adapted as an efficient clinical drug.

Journal, Metastases: Kras oncogene ablation prevents resistance in advanced lung adenocarcinoma. (Pubmed Central) - Apr 4, 2023 Instead, sotorasib resistant tumors displayed amplification of the mutant Kras allele and activation of xenobiotic metabolism pathways, suggesting that reduction of the on-target activity of KRASG12C inhibitors is the main mechanism responsible for the onset of resistance. In sum, our results suggest that resistance to KRAS inhibitors could be prevented by achieving a more robust inhibition of KRAS signaling mimicking the results obtained upon Kras ablation.

Journal: Glimmers of hope for targeting oncogenic KRAS-G12D. (Pubmed Central) - Mar 16, 2023 Recently, through extensive structure-based drug design from Mirati Therapeutics, a novel non-covalent KRAS-G12D inhibitor, MRTX1133, showed significant preclinical antitumor activity in KRAS-G12D-bearing tumor cells, especially pancreatic ductal adenocarcinoma. Here, we discuss the selectivity, efficacy, toxicity, and potential application challenges of this novel targeted protein inhibitor.
