Osimertinib (AZD9291) is a third-generation EGFR-tyrosine kinase inhibitor (TKI) that selectively inhibits the activating EGFR mutation and T790M mutation, and is currently used globally to treat EGFR-mutant non-small cell lung cancer (NSCLC). However, acquired resistance to osimertinib is inevitable.
Epidermal growth factor receptor (EGFR) exon 20 insertions comprise 4-10 % of EGFR mutations in non-small cell lung cancer (NSCLC) and are associated with primary resistance to first and second generation EGFR tyrosine kinase inhibitors (TKIs). In vitro and preclinical animal studies have shown that osimertinib exerts antitumor activity against EGFR exon 20 mutation positive NSCLC. We report on a cohort of advanced stage NSCLC patients who harbor an EGFR exon 20 mutation and received osimertinib treatment.
Osimertinib (AZD9291), a third-generation, mutation-selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (EGFR-TKI), is an approved drug for patients who have non-small-cell lung cancer (NSCLC) with activating EGFR mutations or those harboring a resistant T790M mutation. Unfortunately, all patients eventually relapse and develop resistance to osimertinib. The current study addressed whether ERK inhibition exerts effects similar to those produced by MEK inhibition in overcoming acquire...
Osimertinib is a key drug for cancer patients with EGFR mutations. However, there is little information about its safety in cancer patients who require hemodialysis (HD) for chronic renal failure, despite notable increases in their numbers. Herein, we examined osimertinib safety in such a patient via pharmacokinetics analysis. A 66-year-old man was diagnosed with relapsed stage IV non-small cell lung cancer with an EGFR mutation in exon 21 (L858R) 2 years after stereotactic body radiotherapy. He was underg...
The understanding of histo-molecular mechanisms associated with resistance to osimertinib is a critical step to define the optimal treatment strategy in advanced EGFR-mutated Non-Small-Cell-Lung-Cancer (NSCLC).
This study assesses different technologies for detecting epidermal growth factor receptor (EGFR) mutations from circulating tumor DNA in patients with EGFR T790M-positive advanced non-small cell lung cancer (NSCLC) from the AURA3 study (NCT02151981), and it evaluates clinical responses to osimertinib and platinum-pemetrexed according to the plasma T790M status.
Intramedullary spinal cord metastases (ISCMs) of non-small cell lung cancer (NSCLC) constitute a serious if infrequent complication, characterised by rapid progression of neurological deficits, with poor prognosis. We describe a 52-year-old man with ISCMs secondary to lung adenocarcinoma who acquired the T790M mutation of the epidermal growth factor receptor (EGFR) after previous use of a first-generation EGFR tyrosine kinase inhibitor (TKI); he was successfully treated with osimertinib. This is the first r...
In an early-phase study involving patients with advanced non-small-cell lung cancer (NSCLC), the response rate was better with nivolumab plus ipilimumab than with nivolumab monotherapy, particularly among patients with tumors that expressed programmed death ligand 1 (PD-L1). Data are needed to assess the long-term benefit of nivolumab plus ipilimumab in patients with NSCLC.
Osimertinib is an effective third-generation tyrosine kinase inhibitor (TKI) for EGFR-mutant lung cancers. However, treatment for patients with acquired resistance to osimertinib remains challenging. We characterized a novel EGFR mutation in exon 20 that was acquired while on osimertinib.
The third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) osimertinib has demonstrated significant clinical benefit in EGFR T790M-mutated non-small-cell lung cancer (NSCLC) patients, with extensive research focusing on the mechanisms of acquired resistance. However, there are limited studies on second-line treatment options for EGFR T790M-negative patients and their clinical outcomes.
Approximately 10% of patients with epidermal growth factor receptor (EGFR) mutation-positive non-small-cell lung cancer (NSCLC) harbor uncommon mutations. Here, we report the efficacy and safety of osimertinib in patients with NSCLC harboring uncommon EGFR mutations.
Although osimertinib, an EGFR tyrosine kinase inhibitor, has become the standard therapy for treating non-small cell lung cancer (NSCLC) patients with EGFR-activating mutation, upregulation of MCL-1 induces acquired resistance to osimertinib. Bufalin, a natural digoxin-like ingredient isolated from a traditional Chinese medicine Chan Su, has been shown to downregulate MCL-1 in NSCLC cells. However, whether bufalin reverses this acquired resistance to osimertinib in NSCLC cells remains unclear. In this study...
In this phase I study (BLOOM), osimertinib, a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), was evaluated in patients with leptomeningeal metastases (LMs) from EGFR-mutated (EGFRm) advanced non-small-cell lung cancer (NSCLC) whose disease had progressed on previous EGFR-TKI therapy.
Brief Report: EGFR-mutated lung cancers resistant to osimertinib through EGFR-C797S respond to 1 generation reversible EGFR inhibitors but eventually acquire EGFR-T790M/C797S in preclinical models and clinical samples.
Osimertinib is approved for advanced epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC), and identification of on-target mechanisms of resistance (i.e. EGFR-C797S) to this 3 generation EGFR inhibitor are evolving. Whether durable control of subsequently osimertinib-resistant NSCLC with EGFR-sensitizing mutation (SM)/C797S is possible with 1 generation EGFR inhibitors (such as gefitinib or erlotinib) remains underreported, as does the resultant acquired resistance profile.
Osimertinib is the current recommended treatment for EGFR T790M-positive NSCLC following EGFR-TKI therapy. However, resistance to osimertinib therapy is inevitably acquired after a period of effective treatment. We had a patient suffering from EGFR L858R/T790M-positive NSCLC who initially responded to osimertinib therapy but eventually developed resistance. Plasma cell-free DNA analysis revealed the occurrence of exon-16-skipping HER2, which may resulted in the HER2 splice variant, HER2D16. HER2D16 has neve...
Epidermal growth factor receptor mutated (EGFRm) non-small cell lung cancer (NSCLC) tumors occasionally express programmed cell death ligand 1 (PD-L1), though frequency and clinical-relevance are not fully characterized. We report PD-L1 expression in patients with EGFRm advanced NSCLC and association with clinical outcomes following treatment with osimertinib or comparator EGFR tyrosine kinase inhibitors in the FLAURA trial (phase III, NCT02296125).
Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) are standard of care for non-small cell lung cancer (NSCLC) harboring EGFR mutations. However, almost all patients develop resistance after approximately one year 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-posit...
In the FLAURA trial, osimertinib demonstrated superior progression-free survival and a favorable toxicity profile to erlotinib or gefitinib as initial therapy in patients with EGFR-mutated advanced non-small-cell lung cancer. Patient-reported outcomes from FLAURA are discussed here.
Immunotherapies such as the cytotoxic T-lymphocyte-associated protein 4 inhibitor ipilimumab and the programmed cell death protein 1 inhibitor nivolumab have become ubiquitous in cancer treatment. Recently, the FDA approved nivolumab with or without ipilimumab for the treatment of refractory small cell lung cancer. Immunotherapies increase the immune response to cancer cells by interfering with inhibitory molecular pathways that prevent tumor cell killing, thus augmenting tumor cell death without many of th...
The T790M secondary mutation of epidermal growth factor receptor gene (EGFR) is the most common mechanism of acquired resistance to first- or second-generation EGFR tyrosine kinase inhibitors (TKIs). We investigated the association between gene mutation profile in EGFR mutation-positive non-small cell lung cancer (NSCLC) before EGFR-TKI treatment and T790M status after EGFR-TKI treatment.
Immune checkpoint inhibitors have dramatically changed the landscape of therapeutic management of non-small-cell lung cancer (NSCLC). Tumor mutation burden (TMB) is an important biomarker of the response to cancer immunotherapy. We investigated the relationship between TMB and the imaging, histologic, and genetic features in NSCLC.
This retrospective study was designed to investigate the ability of radiomics to predict the mutation status of epidermal growth factor receptor (EGFR) subtypes (19Del and L858R) in patients with non-small-cell lung cancer (NSCLC).
Epidermal growth factor receptor (EGFR) mutations are observed in approximately 15% of patients with non-small cell lung cancer (NSCLC) in the USA. Little is known about treatment patterns in EGFR mutation-positive NSCLC following progression on or after first-line (1L) treatment with first- or second-generation EGFR tyrosine kinase inhibitors (EGFR-TKIs). Osimertinib, a third-generation EGFR-TKI, is a treatment option for patients with EGFR T790M-positive NSCLC following progression on 1L EGFR-TKIs. This s...
Programmed death-ligand 1 (PD-L1) expression is tested by immunohistochemistry (IHC)-22C3, SP263, and SP142. The aim of this study is to evaluate the correlation among the three methods of PD-L1 IHC in non-small cell lung cancer (NSCLC) and clinical significance of PD-L1 expression in lung adenocarcinoma with an epidermal growth factor receptor (EGFR)-tyrosine kinase domain mutation.
