Unlabelled: KRAS is the most frequently mutated oncogene, harboring mutations in approximately one in seven cancers. Allele-specific KRASG12C inhibitors are currently changing the treatment paradigm for patients with KRASG12C-mutated non-small cell lung cancer and colorectal cancer. The success of addressing a previously elusive KRAS allele has fueled drug discovery efforts for all KRAS mutants. Pan-KRAS drugs have the potential to address broad patient populations, including KRASG12D-, KRASG12V-, KRASG13D-, KRASG12R-, and KRASG12A-mutant or KRAS wild-type-amplified cancers, as well as cancers with acquired resistance to KRASG12C inhibitors. Here, we review actively pursued allele-specific and pan-KRAS inhibition strategies and their potential utility.
Significance: Mutant-selective KRASG12C inhibitors target a fraction (approximately 13.6%) of all KRAS-driven cancers. A broad arsenal of KRAS drugs is needed to comprehensively conquer KRAS-driven cancers. Conceptually, we foresee two future classes of KRAS medicines: mutant-selective KRAS drugs targeting individual variant alleles and pan-KRAS therapeutics targeting a broad range of KRAS alterations.

Purpose: Therapeutic efficacy of KRASG12C(OFF) inhibitors (KRASG12Ci) in KRASG12C-mutant non-small cell lung cancer (NSCLC) varies widely. The activation status of RAS signaling in tumors with KRASG12C mutation remains unclear, as its ability to cycle between the active GTP-bound and inactive GDP-bound states may influence downstream pathway activation and therapeutic responses. We hypothesized that the interaction between RAS and its downstream effector RAF in tumors may serve as indicators of RAS activity, rendering NSCLC tumors with a high degree of RAS engagement and downstream effects more responsive to KRASG12Ci compared to tumors with lower RAS---RAF interaction.

Background: KRAS-G12C inhibitors mark a notable advancement in targeted cancer therapies, yet identifying predictive biomarkers for treatment efficacy and resistance remains essential for optimizing clinical outcomes.
Methods: This systematic meta-analysis synthesized studies available through September 2024 across PubMed, Cochrane Library, SpringerLink, and Embase. Using CRISPR/Cas9 technology, this study generated cells with KEAP1 and STK11 knockouts, and utilized lentiviral vectors to overexpress PD-L1.

KRAS is a potent oncogenic driver which results in downstream hyperactivation of MAPK signaling, while simultaneously increasing replication stress (RS) and accumulation of DNA damage. KRASG12C mutations are common and targetable alterations. Therapeutic inhibition of KRASG12C and eventual resistance to these inhibitors are also known to drive RS and DNA damage through adaptive mechanisms that maintain addiction to high MAPK signaling.

Sotorasib is a novel KRAS inhibitor that has shown robust efficacy, safety, and tolerability in patients with KRAS mutation. The objectives of the population pharmacokinetic (PK) analysis were to characterize sotorasib population PK in healthy subjects and patients with advanced solid tumors with KRAS mutation from 6 clinical studies, evaluate the effects of intrinsic and extrinsic factors on PK parameters, and perform simulations to further assess the impact of identified covariates on sotorasib exposures. A two-compartment disposition model with three transit compartments for absorption and time-dependent clearance and bioavailability well described sotorasib PK.
