Abstract
OBJECTIVE To evaluate the safety and efficacy of the novel KRAS-targeting agents, sotorasib and adagrasib, in treating KRAS G12C-mutated non-small cell lung cancer (NSCLC). DATA SOURCES A comprehensive English-based literature search of PubMed and Clinicaltrials.gov between January 2000 and July 2023 was conducted using the terms sotorasib, Lumakras, AMG 510, adagrasib, Krazati, and MRTX849. STUDY SELECTION AND DATA EXTRACTION Relevant prescribing information, clinical trials, and treatment guidelines were evaluated. DATA SYNTHESIS Sotorasib and adagrasib received accelerated US Food and Drug Administration (FDA) approval following pivotal phase I/II clinical trials. Sotorasib, a first-in-class KRAS inhibitor, demonstrated an overall response rate (ORR) of 41% and a progression-free survival (PFS) of 6.3 months. In a phase III confirmatory trial, sotorasib showed significantly longer PFS compared with docetaxel (5.6 vs. 4.5 months; P = 0.0017). Adagrasib produced an ORR of 42.9% and a PFS of 6.5 months. Both drugs present unique safety profiles, with common toxicities, including diarrhea, musculoskeletal pain, fatigue, and hepatotoxicity. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE With KRAS mutations being among the most common oncogenic alterations in NSCLC, sotorasib and adagrasib offer new therapeutic avenues for this previously "undruggable" target. Current treatment guidelines list sotorasib and adagrasib as second-line options in patients with confirmed KRAS G12C-mutated NSCLC. Additional studies are required to further differentiate the safety and efficacy profiles of these 2 agents and identify their optimal place in therapy. CONCLUSION Sotorasib and adagrasib demonstrated promising outcomes in targeting the constitutively active KRAS G12C oncogenic driver, underscoring the need for further research to optimize their therapeutic application in this high-risk population.

[PMID: 38734764 DOI: 10.1038/s41417-024-00778-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 03/22/2024] [Accepted: 04/22/2024] [Indexed: 05/13/2024]
Abstract
Lung malignant tumors are a type of cancer with high incidence and mortality rates worldwide. Non-small cell lung cancer (NSCLC) accounts for over 80% of all lung malignant tumors, and most patients are diagnosed at advanced stages, leading to poor prognosis. Over the past decades, various oncogenic driver alterations associated with lung cancer have been identified, each of which can potentially serve as a therapeutic target. Rat sarcoma (RAS) genes are the most commonly mutated oncogenes in human cancers, with Kirsten rat sarcoma (KRAS) being the most common subtype. The role of KRAS oncogene in NSCLC is still not fully understood, and its impact on prognosis remains controversial. Despite the significant advancements in targeted therapy and immune checkpoint inhibitors (ICI) that have transformed the treatment landscape of advanced NSCLC in recent years, targeting KRAS (both directly and indirectly) remains challenging and is still under intensive research. In recent years, significant progress has been made in the development of targeted drugs targeting the NSCLC KRASG12C mutant subtype. However, research progress on target drugs for the more common KRASG12D subtype has been slow, and currently, no specific drugs have been approved for clinical use, and many questions remain to be answered, such as the mechanisms of resistance in this subtype of NSCLC, how to better utilize combination strategies with multiple treatment modalities, and whether KRASG12D inhibitors offer substantial efficacy in the treatment of advanced NSCLC patients.

Impact of KRAS G12D subtype and concurrent pathogenic mutations on advanced non-small cell lung cancer outcomes. Clin Transl Oncol 2024; 26:836-850. [PMID: 37490263 PMCID: PMC10981588 DOI: 10.1007/s12094-023-03279-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 07/09/2023] [Indexed: 07/26/2023]
Abstract
PURPOSE Mutations in the Kirsten rat sarcoma viral (KRAS) oncogene constitute a significant driver of lung adenocarcinoma, present in 10-40% of patients, which exhibit heterogeneous clinical outcomes, mainly driven by concurrent genetic alterations. However, characterization of KRAS mutational subtypes and their impact on clinical outcomes in Latin America is limited. METHODS A cohort study was conducted at the National Cancer Institute (INCan) of Mexico. Individuals with advance-staged of adenocarcinoma and KRAS mutations, detected by next-generation sequencing, having undergone at least one line of therapy were included for analysis. Clinical and pathological characteristics were retrieved from institutional database from June 2014 to March 2023. RESULTS KRAS was identified in fifty-four (15.6%) of 346 patients, among which 50 cases were included for analysis. KRASG12D (n = 16, 32%) and KRASG12C (n = 16, 32%) represented the most prevalent subtypes. KRASG12D mutations were associated with female (p = 0.018), never smokers (p = 0.108), and concurrences with EGFR (25.0% vs. 17.6%, p = 0.124) and CDKN2A (18.8% vs. 14.7%, p = 0.157). KRASG12D patients showed a better ORR (66.6% vs. 30.0%; OR 4.66, 95% CI 1.23-17.60, p = 0.023) and on multivariate analysis was significantly associated with better PFS (HR 0.36, 95% CI 0.16-0.80; p = 0.012) and OS (HR 0.24, 95% CI 0.08-0.70; p = 0.009). CONCLUSIONS To our knowledge, this study represents the first effort to comprehensively characterize the molecular heterogeneity of KRAS-mutant NSCLC in Latin American patients. Our data reinforce the current view that KRAS-mutated NSCLC is not a single oncogene-driven disease and emphasizes the prognostic impact of diverse molecular profiles in this genomically defined subset of NSCLC. Further validation is warranted in larger multicenter Latin American cohorts to confirm our findings.

Abstract
KRAS is the most commonly mutated oncogene in advanced, non-squamous, non-small cell lung cancer (NSCLC) in Western countries. Of the various KRAS mutants, KRAS G12C is the most common variant (~40%), representing 10-13% of advanced non-squamous NSCLC. Recent regulatory approvals of the KRASG12C-selective inhibitors sotorasib and adagrasib for patients with advanced or metastatic NSCLC harboring KRASG12C have transformed KRAS into a druggable target. In this review, we explore the evolving role of KRAS from a prognostic to a predictive biomarker in advanced NSCLC, discussing KRAS G12C biology, real-world prevalence, clinical relevance of co-mutations, and approaches to molecular testing. Real-world evidence demonstrates significant geographic differences in KRAS G12C prevalence (8.9-19.5% in the US, 9.3-18.4% in Europe, 6.9-9.0% in Latin America, and 1.4-4.3% in Asia) in advanced NSCLC. Additionally, the body of clinical data pertaining to KRAS G12C co-mutations such as STK11, KEAP1, and TP53 is increasing. In real-world evidence, KRAS G12C-mutant NSCLC was associated with STK11, KEAP1, and TP53 co-mutations in 10.3-28.0%, 6.3-23.0%, and 17.8-50.0% of patients, respectively. Whilst sotorasib and adagrasib are currently approved for use in the second-line setting and beyond for patients with advanced/metastatic NSCLC, testing and reporting of the KRAS G12C variant should be included in routine biomarker testing prior to first-line therapy. KRAS G12C test results should be clearly documented in patients' health records for actionability at progression. Where available, next-generation sequencing is recommended to facilitate simultaneous testing of potentially actionable biomarkers in a single run to conserve tissue. Results from molecular testing should inform clinical decisions in treating patients with KRAS G12C-mutated advanced NSCLC.

Abstract
In non-small cell lung cancer (NSCLC) the most common alterations are identified in the Kirsten rat sarcoma viral oncogene homolog (KRAS) gene, accounting for approximately 30% of cases in Caucasian patients. The majority of mutations are located in exon 2, with the c.34G > T (p.G12C) change being the most prevalent. The clinical relevance of KRAS mutations in NSCLC was not recognized until a few years ago. What is now emerging is a dual key role played by KRAS mutations in the management of NSCLC patients. First, recent data report that KRAS-mutant lung AC patients generally have poorer overall survival (OS). Second, a KRAS inhibitor specifically targeting the c.34G > T (p.G12C) variant, Sotorasib, has been approved by the U.S. Food and Drug Administration (FDA) and by the European Medicines Agency. Another KRAS inhibitor targeting c.34G > T (p.G12C), Adagrasib, is currently being reviewed by the FDA for accelerated approval. From the description of the biology of KRAS-mutant NSCLC, the present review will focus on the clinical aspects of KRAS mutations in NSCLC, in particular on the emerging efficacy data of Sotorasib and other KRAS inhibitors, including mechanisms of resistance. Finally, the interaction between KRAS mutations and immune checkpoint inhibitors will be discussed.

Abstract
Background In patients with non‐small cell lung cancer (NSCLC) harboring driver alterations, the efficacy of immune checkpoint inhibitors (ICIs) remains uncertain. Our study aimed to examine the first‐line ICI efficacy in patients with NSCLC harboring KRAS, MET, FGFR, RET, BRAF, and HER2 alterations in a real‐world setting. Methods This single‐center, retrospective cohort study included patients with advanced NSCLC harboring KRAS, MET, FGFR, RET, BRAF, HER2 alterations or driver‐negative, and were treated with first‐line ICI therapy. Best overall response, progression‐free survival (PFS), and overall survival (OS) were evaluated. Results Seventy‐eight patients with NSCLC were included (median age, 72 years): 67% were men, 15% were never‐smokers, and 83% had adenocarcinoma. The driver alterations involved KRAS (n = 21), MET (n = 6), FGFR (n = 3), RET (n = 2), BRAF (n = 2), HER2 (n = 1), and driver‐negative (n = 43). The partial responses for KRAS, MET, FGFR, RET, BRAF, HER2, and driver‐negative were 57%, 50%, 100%, 50%, 100%, 0%, and 47%, respectively. The median PFS (months) was 16.2 (95% confidence interval [CI]: 6.3– not reached [NR]) for KRAS, 2.8 (95% CI: 2.7–NR) for MET, 11.7 (95% CI: 5.9–NR) for other alterations (FGFR, RET, BRAF, and HER2), and 10.0 (95% CI: 3.7–14.3) for driver‐negative, respectively. The median OS (months) was 31.3 (95% CI: 9.0–NR) for KRAS, not reached for MET, 23.5 (95% CI: 18.3–NR) for other alterations, and 21.1 (95% CI: 15.2–NR) for driver‐negative, respectively. Conclusions The benefit of the first‐line ICI was similar in advanced NSCLC regardless of the driver alterations, except for MET alterations.
