Non-Small Cell Lung Cancer: EGFR Exon 19 Deletion or Exon 21 L858R…First-line therapy...Osimertinib + pemetrexed + (cisplatin or carboplatin) (nonsquamous)…

All patients with nonsquamous NSCLC...New or revised recommendations include the following: Osimertinib is the optimal first-line treatment for patients with activating epidermal growth factor receptor mutations (exon 19 deletion, exon 21 L858R, and exon 20 T790M)…

the Food and Drug Administration approved osimertinib (Tagrisso, AstraZeneca Pharmaceuticals) for adult patients with locally advanced, unresectable (stage III) non-small cell lung cancer (NSCLC) whose disease has not progressed during or following concurrent or sequential platinum-based chemoradiation therapy and whose tumors have EGFR exon 19 deletions or exon 21 L858R mutations, as detected by an FDA-approved test.

...As confirmed by the central laboratory, the tumor contains one of the two common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19del, L858R), alone or in conjunction with other EGFR mutations, including T790M; 7....

...The tumor harbors 1 of the 2 common epidermal growth factor receptor (EGFR) mutations known to be associated with Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) sensitivity (Ex19del or L858R), either alone or in combination with other epidermal growth factor receptor (EGFR) mutations, which may include T790M....

...- A tumour which harbours one of the 2 common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19del, L858R), either alone or in combination with other EGFR mutations (ie, T790M, G719X, Exon20 insertions, S7681 and L861Q)....

...- A tumour which harbours one of the 2 common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19del, L858R), either alone or in combination with other EGFR mutations (eg., T790M, G719X, Exon20 insertions, S7681 and L861Q)....

...Histologically or cytologically confirmed stage IV or recurrent non-squamous non-small cell lung carcinoma with activating EGFR mutations (exon 19 deletion or exon 21 L858R point mutation) and concurrent TP53 mutations; 6....

...According to the ARMS or Super-ARMS or NGS test results of tumor tissue or plasma from a certified laboratory approved by Chinese regulatory authorities, the tumor carries at least one of the 4 rare EGFR mutations (G719X/L861Q/S768I/T790M) (single mutation or compound mutation), but not other EGFR mutations (including ex19del/L858R). ...

...For patients aged <20 years and enrolled in Japan, a written informed consent should be obtained from the patient and his or her legally acceptable representative.- Histologically or cytologically documented non-squamous NSCLC with completely resectable (Stage II - IIIB N2) disease (according to Version 8 of the IASLC Cancer Staging Manual [IASLC Staging Manual in Thoracic Oncology 2016]).- Complete surgical resection of the primary NSCLC must be deemed achievable, as assessed by a Mulit-disciplinary Team (MDT) evaluation (which should include a thoracic surgeon, specialised in oncologic procedures).- Eastern Cooperative Oncology Group (ECOG) PS of 0 or 1 at enrolment, with no deterioration over the previous 2 weeks prior to baseline or day of first dosing.- A tumour which harbours one of the 2 common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19del, L858R), either alone or in combination with other EGFR mutations (ie, T790M, G719X, Exon20 insertions, S7681 and L861Q).`...

...- Newly diagnosed, and histologically documented metastatic non-squamous NSCLC with sensitizing EGFR mutations positive, and classified as stage IV or recurrent NSCLC which are...

This multicenter phase 2 trial evaluated the safety and efficacy of osimertinib and platinum-based chemotherapy (OPP) in patients with previously untreated EGFR-mutated advanced non-squamous non-small cell lung cancer (NSCLC)….Patients received osimertinib 80 mg once daily (QD), with either cisplatin 75 mg/m2 (arm A) or carboplatin (area under the curve [AUC] = 5; arm B), plus pemetrexed 500 mg/m2 for four cycles and maintenance therapy of osimertinib 80 mg QD with pemetrexed 500 mg/m2 every 3 weeks....Overall, for patients with exon 19 deletions (n = 30), the ORR, median PFS, and median OS were 96.7% (95% CI, 90.2–100.0), 30.6 months (95% CI, 24.5–NR), and NR (95% CI, NR–NR). In contrast, for patients with exon 21 L858R (n = 35), the ORR, median PFS, and median OS were 85.7% (95% CI, 74.1–97.3), 33.4 months (95% CI, 18.9–NR), and NR (95% CI, NR–NR)...
