Filter by:Pemetrexed is one of the first-line chemotherapeutic agents for non-squamous non-small cell lung cancer (NSCLC). Since 2017, intrathecal pemetrexed has shown good efficacy for patients with leptomeningeal metastases from NSCLC. It has been recommended as the preferred drug for intrathecal chemotherapy by the Chinese Society of Clinical Oncology (CSCO) guidelines. Tyrosine kinase inhibitors (TKIs) play a promising role in treating non-small cell lung cancer patients with epidermal growth factor receptor (EGFR) mutations. An international multi-center clinical study published in 2019 confirmed that double dose of osimertinib showed significant improvement in leptomeningeal metastases from NSCLC with EGFR exon 19 deletion or exon 21 L858R/T790M mutation. It makes TKIs the mainstay of treatment for patients with EGFR-mutant NSCLC with leptomeningeal metastases. However, the choice of treatment after resistance to targeted therapy is a hot topic in clinical practice, with 78% of patients in the study above who responded to double-dose osimertinib still showing progression at the time of follow-up. The purpose of this study was to observe the safety and efficacy of intrathecal pemetrexed for leptomeningeal metastasis from lung adenocarcinoma that progressed after a double dose of a third-generation TKI such as osimertinib.
This study is an investigator-initiated, prospective, open-label, single-arm, multicenter clinical trial aimed at exploring the antitumor activity of Lorlatinib in ALK-positive NSCLC patients with brain/ leptomeningeal metastases.
This is a prospective, single-arm, open clinical study, which was designed to evaluate the efficacy and safety of an immune checkpoint inhibitor combined with pemetrexed intrathecal injection in the treatment of patients with NSCLC associated with leptomeningeal metastases.
Leptomeningeal metastasis (LM) is a complication of advanced non-small cell lung cancer (NSCLC). The incidence of LM in NSCLC patients is around 3-5 %, reaching 9.4 % of those with an epidermal growth factor receptor (EGFR) mutation. Generally, the efficacy of systemic treatment for LM is limited due to the blood-brain barrier. Osimertinib has a high central nervous system penetration rate, making it the preferred first-line treatment for EGFR-mutant NSCLC. Previous studies indicated that osimertinib had shown promising efficacy in pretreated patients harboring EGFR mutations and LM. However, intracranial disease progression eventually develops, and the prognosis of patients with LM progression after osimertinib is poor. Recently, intrathecal chemotherapy with pemetrexed (IP) was reported to be an alternative treatment in patients with NSCLC and LM. The results from a phase I/II trial examining the efficacy and safety of IP in patients with EGFR-mutant NSCLC after the failure of previous TKI, and 83% of study enrollees received osimertinib before IP. The clinical response rate was 84.6%, and the median overall survival was 9.0 months. Despite initial promising efficacy, further trials are needed to verify these results. Therefore, the investigators plan to conduct a prospective study to examine the safety and effectiveness of IP combined with EGFR-TKI for patients with EGFR mutant NSCLC after osimertinib failure.
A prospective, open-label, multi-center, single-arm study of Almonertinib combined With Bevacizumab for EGFR-mutant NSCLC patients with leptomeningeal metastasis.
The purpose of this study is to observe the clinical efficacy and safety of Durvalumab combined with intrathecal chemotherapy in non-small cell lung cancer with leptomeningeal metastasis
The purpose of this study is to observe the clinical effect and safety of Recombinant Human Endostatin in non-small cell lung cancer with leptomeningeal metastasis
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
This is an open-label Phase 3 study to see if ANG1005 can prolong survival compared to a Physician Best Choice control in HER2-negative breast cancer patients with newly diagnosed leptomeningeal disease and previously treated brain metastases.
The main purpose of this study is to compare the effect of 10 mg and 15 mg methotrexate in the treatment of meningeal carcinomatosis.
