Abstract

BACKGROUND: . METHODS: p.G12C mutation. Patients received sotorasib orally once daily. The primary end point was safety. Key secondary end points were pharmacokinetics and objective response, as assessed according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. RESULTS: A total of 129 patients (59 with NSCLC, 42 with colorectal cancer, and 28 with other tumors) were included in dose escalation and expansion cohorts. Patients had received a median of 3 (range, 0 to 11) previous lines of anticancer therapies for metastatic disease. No dose-limiting toxic effects or treatment-related deaths were observed. A total of 73 patients (56.6%) had treatment-related adverse events; 15 patients (11.6%) had grade 3 or 4 events. In the subgroup with NSCLC, 32.2% (19 patients) had a confirmed objective response (complete or partial response) and 88.1% (52 patients) had disease control (objective response or stable disease); the median progression-free survival was 6.3 months (range, 0.0+ to 14.9 [with + indicating that the value includes patient data that were censored at data cutoff]). In the subgroup with colorectal cancer, 7.1% (3 patients) had a confirmed response, and 73.8% (31 patients) had disease control; the median progression-free survival was 4.0 months (range, 0.0+ to 11.1+). Responses were also observed in patients with pancreatic, endometrial, and appendiceal cancers and melanoma. CONCLUSIONS: p.G12C mutation. Grade 3 or 4 treatment-related toxic effects occurred in 11.6% of the patients. (Funded by Amgen and others; CodeBreaK100 ClinicalTrials.gov number, NCT03600883.).

  • Adagrasib and sotorasib are both selective covalent KRAS G12C inhibitors, but they differ pharmacologically, including half-life, dose-dependent exposure, and potential CNS penetration.

    “Adagrasib and sotorasib are both selective covalent inhibitors of KRAS G12C, but pharmacologic differences between the two drugs have been reported, including half-life (5 hours for sotorasib and 23 hours for adagrasib), dose-dependent exposure with adagrasib, and potential CNS penetration with adagrasib.22,29”

    From Adagrasib with or without Cetuximab in Colorectal Cancer with Mutated <i>KRAS</i> G12C (2023) · cites this paper as [29]

    The Abstract (Background) and Discussion identify sotorasib as a selective, covalent KRAS G12C inhibitor. Results (Pharmacokinetics; page unavailable) report its mean elimination half-life as 5.5 hours, consistent with the cited 5-hour figure. Our copy does not address adagrasib’s selectivity, half-life, dose-dependent exposure, or potential CNS penetration, so it does not establish the comparison between the drugs. (LLM, conf=0.91)

  • Sotorasib and adagrasib were effective at halting the growth of G12C-mutant cancer cells in 2-dimensional, 3-dimensional, and xenograft models.

    “Sotorasib and adagrasib, two prominent members of this class, were effective at halting the growth of G12C-mutant cancer cells in 2-dimensional, 3-dimensional, and xenograft models, clearing the path for clinical trials [48,49,50,51].”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [51]

    The introductory passage following the Abstract Conclusions reports that preclinical sotorasib treatment led to durable tumor regression in mice bearing KRAS p.G12C tumors, supporting part of the claim. Our copy does not report results for adagrasib or specify 2-dimensional, 3-dimensional, or xenograft models. Page numbers are not available in the supplied copy. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • In 2021, the FDA approved sotorasib for the treatment of adult patients with KRAS G12C-mutated NSCLC, while adagrasib received similar approval the following year.

    “In 2021, the FDA approved sotorasib for the treatment of adult patients with KRAS G12C-mutated NSCLC, while adagrasib received similar approval the following year [48,50,51,52,53].”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [51]

    The Methods and Results describe sotorasib treatment in adults with KRAS G12C-mutated NSCLC. The paper does not report FDA approval of sotorasib in 2021 or adagrasib in 2022; its Background says no KRAS-targeting therapies had been approved at the time of publication in 2020. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The data from CodeBreak 100 for sotorasib and KRYSTAL-1 for adagrasib led to the approval of these inhibitors to treat G12C-mutant NSCLC.

    “The data from both CodeBreak 100 for sotorasib and KRYSTAL-1 for adagrasib led to the approval of these inhibitors to treat G12C-mutant NSCLC [51,53,94].”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [51]

    The Results > Efficacy section reports responses to sotorasib in patients with KRAS G12C-mutant NSCLC, supporting the sotorasib-trial portion of the claim. This paper does not report KRYSTAL-1 data for adagrasib or establish that either trial’s data led to regulatory approval. Page numbers are not available in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Even in NSCLC, median response rates to single-agent KRAS G12C inhibitors were in the 6-7 month range before relapse occurred.

    “Even in NSCLC, where the compounds were approved, median response rates were in the 6–7 month range before relapse occurred, indicating that the vast majority of tumors develop resistance to single-agent KRAS G12C inhibitors [51,95].”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [51]

    The Results (Efficacy, NSCLC) report median progression-free survival of 6.3 months, which matches the cited 6–7-month range. But median duration of response was 10.9 months, not 6–7 months. The Discussion notes that some patients progressed soon after an initial response; it does not establish that the vast majority of tumors developed resistance. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
