Pulsatile High-dose Furmonertinib in EGFR-mutant NSCLC With Leptomeningeal Metastasis
The goal of this clinical trial is to clarify the efficacy and safety of the high-dose alternate-day furmonertinib in NSCLC with leptomeningeal metastasis. It will also explore the mechanism by which the high-dose alternate-day administration regimen enhances efficacy from a pharmacokinetic perspective, and investigate the impact of co-occurring mutations on the efficacy and prognosis of furmonertinib in the treatment of EGFR-mutant NSCLC with leptomeningeal metastasis. The main questions it aims to answer are: Does the high-dose alternate-day administration regimen have definite efficacy? Does the high-dose alternate-day administration regimen have favorable safety? Does the high-dose alternate-day administration regimen improve efficacy by increasing the cerebrospinal fluid (CSF) concentration and CSF penetration rate of the drug? Which co-occurring mutations may affect the efficacy and prognosis of patients with EGFR-mutant NSCLC and leptomeningeal metastasis? Participants will enter Cohort A (320mg qod po) or Cohort B (160mg qd po) to receive furmonertinib based on their own willingness and the clinician's decision, until disease, progression or uncontrollable adverse reactions occur. All patients in Cohort A will undergo efficacy and safety evaluation, with some also participating in pharmacokinetic study; patients in Cohort B will only undergo pharmacokinetic study. Efficacy and safety evaluation will be conducted through imaging examinations, neurological function assessment scales, quality of life self-assessment scales, and adverse event records. Pharmacokinetic study will be carried out by detecting the plasma concentrations and CSF concentrations of furmonertinib and its active metabolites, and calculating the CSF penetration rate for evaluation.

Intrathecal Pemetrexed for Leptomeningeal Metastasis in EGFR-Mutant NSCLC
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.

Double-Dose Third-Generation EGFR-TKI Plus Bevacizumab and Intrathecal Chemotherapy for Refractory Leptomeningeal Metastatic NSCLC: A Phase II Study
The goal of this clinical trial is to explore the efficacy and safety of double-dose third-generation EGFR-TKI combined with bevacizumab and intrathecal chemotherapy in treating advanced non-small cell lung cancer (NSCLC) patients with leptomeningeal metastasis that progressed after prior standard-dose third-generation EGFR-TKI treatment. It also aims to investigate the correlation between cerebrospinal fluid genetic characteristics and prognosis as well as subsequent efficacy prediction in patients with leptomeningeal metastasis after resistance to standard-dose third-generation EGFR-TKI. The main questions it intends to answer are: Does this combined treatment regimen improve leptomeningeal metastasis response rate (LM-ORR) evaluated by RANO-LM? What adverse events occur in patients during the treatment with this combined regimen? Researchers will conduct a single-arm phase II prospective study to assess the effectiveness and safety of the combined treatment, without a control group comparison. Participants will: Receive double-dose third-generation EGFR-TKI (osimertinib 160mg qd, furmonertinib 160mg qd, or almonertinib 220mg qd) + intrathecal pemetrexed (induction phase: 10mg twice a week for 4 weeks; maintenance phase: 10mg once a week for 4 weeks; consolidation phase: 30mg every 4 weeks until disease progression or intolerable toxicity) + bevacizumab 7.5mg/kg. Undergo screening assessments within 28 days before enrollment, including tumor imaging, laboratory tests, and cerebrospinal fluid examination. During the treatment period, conduct regular checkups and tests (such as blood routine, blood biochemistry, electrocardiogram, and imaging examinations) according to the protocol (once every 4 weeks in the first two treatment cycles, then once every 8 weeks). Complete quality of life assessment using the QLQ-C30 scale every 4 weeks and record changes in neurological symptoms and ECOG scores.

Intrathecal Pemetrexed for Leptomeningeal Metastasis From Lung Adenocarcinoma That Progressed After Osimertinib.
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.

Intra-pemetrexed Plus Third-generation Small Molecule TKI Drugs (e.g. 'Osimertinib') Versus Third-generation Small Molecule TKI Drugs Alone for Leptomeningeal Metastasis From Epidermal Growth Factor Receptor Mutation-Positive Non-Small-cell Lung Cancer
Intrathecal chemotherapy is one of the mainstay treatment options for leptomeningeal metastases. 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 the treatment of non-small cell lung cancer patients with epidermal growth factor receptor (EGFR) mutations. Due to its small molecule properties, it can effectively penetrate the central nervous system barrier and deliver an effective antitumor effect. 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, whether third-generation small molecule TKI drugs (e.g. 'osimertinib') combined with intrathecal pemetrexed could benefit patients with LM from EGFR- mutant NSCLC remains undetermined.

Firmonertinib Combined With Intrathecal Injection for the Treatment of EGFR Mutant NSCLC With Leptomeningeal Metastases
Leptomeningeal metastases (LM) are a relatively rare site of metastasis in advanced non-small cell lung cancer (NSCLC), and LM patients have a poor prognosis. Numerous retrospective studies have reported that high-dose Firmonertinib can also effectively increase patient prognosis and have tolerable side effects, but there is a lack of prospective studies to confirm this. In addition, there are currently no good biomarkers for monitoring the efficacy of LM treatment. cfDNA testing can be used for early cancer screening, monitoring tumor progression, evaluating treatment response, and discovering drug resistance mechanisms. Due to the influence of the blood-brain barrier, the level of cfDNA in the plasma of LM patients is often very low, and the detection of cfDNA in cerebrospinal fluid (CSF) is more advantageous. Therefore, exploring the dynamic monitoring of LM treatment efficacy using CSF cfDNA is of great significance for improving patient prognosis. Based on this, the applicant intends to conduct a prospective, multicenter, single-arm, post-market exploratory clinical trial on the treatment methods and efficacy monitoring of NSCLC-LM patients. The aim was to explore whether cfDNA has the potential to become a biomarker for LM efficacy monitoring and to validate the efficacy and safety of high-dose fumatinib combined with intrathecal injection in the treatment of NSCLC-LM patients.
