AZD4625 / AstraZeneca - LARVOL DELTA

Modeling response to the KRAS-G12C inhibitor AZD4625 in KRASG12C NSCLC patient-derived xenografts reveals insights into primary resistance mechanisms. (PubMed, Br J Cancer) - "Our findings confirm AZD4625 as a highly active KRASG12C inhibitor. This data also supports the use of PDX models in understanding resistance mechanisms that may be leveraged to develop more active combination therapies."

KRASG12C inhibitor resistance in patient-derived non-small cell lung cancer models (AACR 2024) - "We leveraged our patient-derived xenograft (PDX) and xenograft-derived organoid (XDO) development programs to study primary resistance to the novel G12Ci, AZD4625. Twelve KRASG12C PDX models were established which recapitulated patient tumor histology, and genomic, transcriptomic, and methylome profiles... PDX and XDO are useful models to study resistance to this novel class of inhibitor, with the KRASG12C NSCLC PDX models exhibiting a treatment response rate that is similar to those observed in clinical trials. Global proteomics suggests uniqueness of each model in our cohort, hinting that a universal combination of specific targeted agents to treat KRASG12C LUAD tumors may be insufficient."

AstraZeneca pays $24M to join race for next big KRAS opportunity, bagging Chinese rival to Mirati asset (FierceBiotech) - "The deal furthers AstraZeneca’s long-standing interest in KRAS. In 2012, the drug developer licensed an anti-KRAS antisense oligonucleotide, AZD4785, from Ionis. That candidate never progressed past phase 1, with AstraZeneca pulling the plug after wrapping up a trial in 2019, but the company’s research teams continued to work on the target...After discovering the KRAS G12C inhibitor AZD4625, AstraZeneca tweaked the molecule to generate the clinical candidate AZD4747...the potential for its molecule to penetrate the central nervous system could offer a point of differentiation."
