Filter by:immune checkpoint inhibitor combined with recombinant human endostatin can improve the 3-month OS rate of leptomeningeal metastasis of lung cancer, and the combination is safe
Intrathecal chemotherapy is one of the mainstay treatment options for leptomeningeal metastases. Owing to the limited number of agents available for intrathecal chemotherapy, it is crucial to find a novel agent with efficacy and safety. In our phase 1 study, intrathecal pemetrexed showed controllable toxicities and potential promising efficacy for refractory leptomeningeal metastases from non-small-cell lung cancer patients. In our further study, intrathecal pemetrexed combined with involved-field radiation therapy was administered as the first-line intrathecal chemotherapy for leptomeningeal metastases from solid tumors. In this study, intrathecal pemetrexed combined with involved-field radiation therapy showed feasibility and controllable adverse events. It has been proved that pemetrexed as a novel intrathecal drug exhibited promising antitumor effects in cerebrospinal fluid. Moreover, the concomitant therapeutic modality is an optimal treatment option for leptomeningeal metastases from solid tumors. Central nervous system radiotherapy is a part of the specific treatment of leptomeningeal metastases. Radiotherapy has been proved to improve neurologic function and control of parenchymal brain metastases in leptomeningeal metastases treatment. Additionally, radiotherapy is revealed to improve the efficacy and attenuate toxicity of intrathecal chemotherapy as a result of normal cerebrospinal fluid reestablishing. However, it is still controversial whether radiotherapy can improve the overall survival. We conduct this study to further demonstrate the efficacy and safety of intrathecal pemetrexed administration for patients with leptomeningeal metastases from solid tumors by multicenter study. Furthermore, the study of effective treatment modality is of great significance. The safety and antitumor activity of intrathecal pemetrexed combined with involved-field radiation therapy and intrathecal pemetrexed alone were also compared to confirm an optimized therapeutic regimen.
Leptomeningeal disease is malignant seeding of the leptomeninges and presents with a variety of symptoms frequently impacting quality of life. With improvement in treatment options, rates of leptomeningeal disease are increasing and currently found in up to 9% of EGFR mutant NSCLC. Systemic therapy may be more effective if it can target the correct molecular aberration. The molecular characterization of central nervous system disease may differ from disease outside of the central nervous system. The aim of this pilot trial is to evaluate for molecular differences between cerebral spinal fluid (CSF) and blood circulating tumor DNA (ctDNA) through the use of ddPCR and BC Cancer NGS panel molecular testing.
To evaluate the efficacy and safety of TY-9591 tablets in the treatment of EGFR mutation-positive non-small cell lung cancer (NSCLC) patients with brain or leptomeningeal metastases.
This is an open-label Phase I clinical study that will administer a single dose of 186RNL via intraventricular catheter for treatment of Leptomeningeal Metastases (LM).
A prospective, open-label, multi-center, single-arm study of Almonertinib combined With Bevacizumab for EGFR-mutant NSCLC patients with leptomeningeal metastasis.
Clinical Efficacy and Safety of EGFR-TKI Combined With Nimotuzumab in the Treatment of Leptomeningeal Metastases From Lung Cancer.
Almonertinib is a three-generation epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI), which has shown competitive potential in the second-line treatment against first-generation TKIs. This study aims to explore the efficacy and safety of different doses of almonertinib in the first-line and second-line treatment of brain metastases/meningeal metastases in NSCLC patients.
The purpose of this research is to examine if an experimental drug combination impacts the survival rate of individuals with Leptomeningeal Metastases This research study involves an experimental drug combination. The names of the study drugs involved in this study are: - Pembrolizumab - Lenvatinib
The purpose of this study is to find out if radiation therapy followed by intrathecal trastuzumab and pertuzumab is safe and will result in improved survival in HER2 positive breast cancer which has metastasized to the leptomeninges.
