Osimertinib for Japanese patients with T790M-positive advanced non-small-cell lung cancer: A pooled subgroup analysis.
    Cancer science, 2019, Volume: 110, Issue:9

    Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) are the standard of care for non-small-cell lung cancer (NSCLC) patients harboring EGFR mutations. However, almost all patients develop resistance after approximately 1 y of treatment, with >50% of cases due to the T790M secondary mutation of the EGFR gene. A large global Phase III study (AURA3) demonstrated that osimertinib significantly prolonged progression-free survival (PFS) over platinum-doublet chemotherapy in patients with T790M-positive NSCLC who had progressed on previous EGFR-TKI therapy. However, it is not clear whether efficacy or safety of osimertinib in Japanese patients is similar to the overall population. We report a pre-planned subgroup analysis of pooled Phase II data from the AURA Extension and AURA2 trials to investigate the efficacy and safety of osimertinib in Japanese patients. This study included 81 Japanese patients. Patients were administered 80 mg osimertinib orally once daily until disease progression. The main endpoints were objective response rate (ORR), PFS, and safety. The ORR was 63.6% and median PFS was 13.8 mo. Overall survival rate at 36 mo was 54.0%. The most common all-cause adverse events (AEs) were rash (grouped term; 65.4%), diarrhea (51.9%), paronychia (grouped term; 49.4%), and dry skin (grouped term; 39.5%). Most AEs were grade 1-2. Five patients (6.2%) developed interstitial lung disease, resulting in two deaths (2.5%). Osimertinib demonstrated favorable ORR and PFS in Japanese patients, similar to the overall population. Additionally, osimertinib has good efficacy and a manageable safety profile in Japanese patients with NSCLC who had acquired resistance due to the T790M mutation.

    Osimertinib is a key drug for treating epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC). Genetic differences may be associated to adverse events (AEs) induced by osimertinib. This retrospective observational multicenter study evaluated the association of genotypes, including STAT3 -1697C>G, CYP3A5 6986A>G, and ABCG2 421C>A, with the incidence of osimertinib-induced AEs in patients with EGFR mutation-positive NSCLC.. A total of 85 patients treated with osimertinib (Institution A: 33 patients, Institution B: 52 patients) were enrolled in the study. Single nucleotide polymorphisms were determined by real-time PCR, and the incidence of AEs was compared for each genotype.. Paronychia incidence was 59% for the CC genotype, 19% for the CG genotype, and 19% for the GG genotype at STAT3 -1697C>G. A genotype-related trend was observed (Cochran-Armitage test, p=0.009). Multivariate analysis showed that the CC genotype at STAT3 -1697C>G and female sex were significant independent factors associated with paronychia [odds ratio (OR)=6.41, 95% confidence interval (CI)=1.94-21.20 and OR=3.40, 95%CI=1.03-11.22, respectively]. The incidence of diarrhea was 53% for the CC genotype, 30% for the AC genotype, and 29% for the AA genotype at ABCG2 421C>A, and a genotype-related trend was observed (p=0.048). However, the CC genotype at ABCG2 421C>A was not a significant independent factor associated with diarrhea in multivariate analysis. No significant associations were detected between other polymorphisms and the incidence of AEs.. STAT3 -1697C>G may be a novel risk factor for osimertinib-induced paronychia in patients with NSCLC.
