Pulsatile High-dose Furmonertinib in EGFR-mutant NSCLC With Leptomeningeal Metastasis
Source: ClinicalTrials.gov · Last updated 2 Apr 2026
Brief summary (registry, in English)
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.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Patients with a severe allergic diathesis, especially those who have experienced severe drug allergies or other serious adverse reactions during previous treatment with tyrosine kinase inhibitors (TKIs).
Other illness
- Complicated with severe or uncontrolled systemic diseases, including active infection, electrolyte disturbance, bleeding tendency, etc.
- Suffering from other malignant tumors or having a history of other malignant tumors
- Complicated with severe brain diseases or mental illnesses that affect the patient's ability to report symptoms by themselves
Other
- Unable to complete the baseline assessment form
- Pregnant or lactating women, or those with planned pregnancy during the study or within 6 months after the study ends
- Presence of central nervous system complications requiring emergency neurosurgical intervention
- Individuals without legal capacity, or those for whom medical or ethical reasons affect the continuation of the study
- Other circumstances deemed unsuitable for participation in this study by the researcher.
Who the study is looking for
- Patients with non-small cell lung cancer (NSCLC) confirmed by histopathological or cytopathological examination
- Patients with EGFR exon 19 deletion or exon 21 L858R mutation
- Patients with leptomeningeal metastasis (LMD) confirmed by positive cerebrospinal fluid (CSF) cytology (within 28 days prior to the first dose administration) and with at least 1 LMD lesion that can be repeatedly evaluated by magnetic resonance imaging (MRI)
- Patients with disease progression after first-line tyrosine kinase inhibitor (TKI) treatment
- Aged ≥18 years and ≤85 years, with no gender restrictions.
- Sufficient organ function, defined as: absolute neutrophil count ≥ 1.5×10⁹/L, platelet count ≥ 75×10⁹/L, hemoglobin ≥ 90g/L total bilirubin ≤ 1.5×upper limit of normal (ULN) alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5×ULN (for patients with liver metastasis, total bilirubin can be relaxed to ≤ 3×ULN, and ALT/AST can be relaxed to ≤ 5×ULN) serum creatinine ≤ 1.5×ULN or creatinine clearance ≥ 50 mL/min (calculated by the Cockcroft-Gault formula)
- For patients enrolled in the pharmacokinetic study: no prior treatment with furmonertinib (either in combination or as monotherapy)
- Patients who have signed the informed consent form, are willing to receive treatment under this protocol, can adhere to medication administration, and have good compliance.
