Filter by:Leptomeningeal metastasis (LM) is a fatal complication of advanced non-small cell lung cancer (NSCLC) associated with poor prognosis and rapid deterioration of performance status. The incidence of LM is increasing, reaching 3.8% in molecularly unselected NSCLC patients, being more frequent in adenocarcinoma subtype and up to 9% in epidermal growth factor receptor mutation (EGFRm) lung cancer patients, one-third of patients have concomitant brain metastasis . This increased incidence may in part be conducive to the increased survival of patients with EGFRm advanced NSCLC since the introduction of EGFR-tyrosine kinase inhibitions (TKIs).Currently, no standard therapeutic regimen for LM has been established because of its rarity and heterogeneity[11], and no approved therapies exists to specifically target LM in patients with EGFRm NSCLC. TKIs therapy is the first-line treatment of patients with EGFRm of NSCLC. The leptomeningeal space is a sanctuary site for tumour cells and therapeutic agents due to the presence of an active blood-brain barrier (BBB), so CSF concentration is an important factor affecting treatment of LM by TKIs. Standard-dose first- and second-generation EGFR-TKIs have good systemic efficacy but sub-optimal CNS penetration, as evidenced by preclinical studies of brain distribution and clinical reports of CSF penetration[15, 16]. Osimertinib is a third-generation EGFR-TKI, irreversible, oral EGFR-TKI that potently and selectively inhibits both EGFR-TKI sensitizing and EGFR T790M resistance mutations, which has demonstrated efficacy in NSCLC CNS metastasis[17-22]. Preclinical, I/II clinical studies and AURA program (AURA extension, AURA2, AURA17 and AURA3) have shown that Osimertinib has higher brain permeability than the first- and second-generation. Bevacizumab is a recombinant humanized monoclonal antibody against vascular endothelial growth factor (VEGF), animal studies and autopsy specimens show that VEGF plays an important role in LM. VEGF and EGFR share many overlapping and parallel downstream pathways. The biological rationale shows that inhibiting of EGFR and VEGR signaling pathways could improve the efficacy of antitumor and remove the resistance of EGFR inhibition. Besides, preclinical researches have shown the similar results. Based on these, numbers of clinical trials have confirmed that VEGF inhibitors in combination with EGFR-TKI significantly prolong patients' survival.
Treatment of non-small cell lung cancer (NSCLC) with Epidermal Growth Factor Receptor (EGFR) mutation is mainly based on tyrosine kinase inhibitors (TKIs) targeting EGFR. 1st or 2nd generation inhibitors have been shown to be superior to chemotherapy in terms of Progression-Free Survival (PFS) when used as 1st line treatment. In case of progression at several metastatic sites, systemic treatment will be considered and will depend on the presence of the TKI resistance mutation, the T790M mutation. In the presence of the T790M mutation, osimertinib is superior to chemotherapy in terms of progression-free survival, while in the absence of the T790M mutation, platinum salt chemotherapy is recommended. In case of local progression, treatment of the site in progression by radiotherapy and/or surgery is considered. As these local treatments can cause long-term adverse effects, systemic treatments are increasingly being considered in this indication. Brain and leptomeningeal metastases are the most frequent isolated site of progression in EGFR mutated patients treated with TKI. The high frequency of isolated cerebral and leptomeningeal progression is a consequence of the lower diffusion of 1st and 2nd generation TKIs in the central nervous system (CNS). Osimertinib is a 3rd generation TKI that has the particularity of overcoming the T790M mutation and having greater brain penetration than 1st or 2nd generation TKIs, which could make it an attractive therapeutic option in the event of brain progression or leptomeningeal progression. However, its efficacy in patients with cerebral or leptomeningeal metastases is still poorly understood.
Leptomeningeal metastasis (LM) is a devastating and terminal complication of advanced non-small-cell lung cancer (NSCLC), especially in patients harboring epidermal growth factor receptor (EGFR) mutations. Osimertinib is an oral,third-generation, irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that selectively inhibits both EGFR-TKI-sensitizing and EGFR T790M resistance mutations .AURA I/II study and other preclinical study suggested that Osimertinib exhibited a better blood-brain barrier(BBB) penetration than the other EGFR-TKIs (gefitinib, erlotinib, or afatinib).The BLOOM 、AURA and FLURA study demonstrated that osimertinib showed encouraging activity and manageable tolerability in pretreated EGFR-mutant NSCLC patients with LM. Bevacizumab is a monoclonal antibody against vascular endothelial growth factor (VEGF). Animal study and autopsy specimens showed that VEGF is an essential factor in LM. Recently study showed EGFR-TKIs plus bevacizumab prolonged PFS and OS in patients with EGFR-mutant NSCLC and multiple brain mteastasis when compared with EGFR-TKIs alone. Howerver osimertinib combined with bevacizumab could benefit patients with LM from EGFR- mutant NSCLC remains undetermined. Therefore, the purpose of the study is to evaluate the safety and efficacy of osimertinib combined with bevacizumab for EGFR- mutant non-small cell lung cancer with leptomeningeal metastasis
The concomitant co-mutation with epidermal growth factor receptor (EGFR) mutation might influence the clinical outcomes. The investigators will identify the impact of concommitant mutation on clinical outcome in patients with advanced -EGFR mutated adenocarcinoma. The investigators will compare the genetic alterations between tumors of pre and post Tyrosin Kinase Inhibitor(TKI) treatments and predict the resistance mechanism for EGFR-TKIs by next-generation sequencing(NGS) analysis.
This project will recruit 40 EGFR-mutant metastatic non-small cell lung cancer patients who failed any EGFR tyrosine kinase inhibitors. All recruited patients will receive 1200mg Azetolizumab administered over 60 minutes (1st cycle) and 30 minutes (2nd cycle onwards) intravenously, as well as 7.5mg/kg bevacizumab administered over 90 minutes (1st cycle), 60 minutes (2nd cycle) and 30 minutes (3rd cycle onwards) for every 3 weeks, until radiographically documented disease progression, unacceptable toxicity as judged by investigators or patient withdrawal. The primary objective is to assess the progression-free survival of this treatment population, and to identify potential genomic and immunologic biomarkers for treatment response. Objective response rate (ORR) will be the primary efficacy endpoint.
To compare the efficacy of simultaneous EGFR-TKI and chemotherapy with that of sequential treatment after patients gradually progressed from first-line EGFR-TKI treatment. Patients who had gradual progression and EGFR-T790M mutation-negative were randomly divided into two groups: in concurrent group, patients were treated with pemetrexed plus cisplatin along with the same EGFR-TKI; in sequential group, patients continued with EGFR-TKI until the disease progressed again according to the RECIST criteria, and then switched to chemotherapy. We evaluated progression-free survival (PFS) and overall survival (OS) time of patients. For sequential group, PFS was PFS1 (gradual progression to discontinue EGFR-TKI) plus PFS2 (chemotherapy alone).
This phase II trial studies how well targeted therapy works in treating patients with incurable non-small cell lung cancer with a genetic mutation. Giving drugs that target other genetic mutations or other specific proteins may work better when a patient has cancer caused by a driver mutation and the treatment that targets that mutation stops working.
This phase I/II trial studies the side effects and best dose of plinabulin when given together with nivolumab and to see how well they work in treating patients with stage IIIB-IV non-small cell lung cancer that has come back or spread to other places in the body. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as plinabulin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab and plinabulin together may work better at treating patients with non-small cell lung cancer.
