An interventional study of Furmonertinib 320mg qod po and Furmonertinib 160mg qd po in NSCLC (Advanced Non-small Cell Lung Cancer), Leptomeningeal Metastasis and Furmonertinib, sponsored by Guangzhou University of Traditional Chinese Medicine. Recruiting at 1 site in China. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2026-04-02.

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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.
Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Quality of life evaluation
Patient self-assessments of quality of life will be conducted using the Chinese versions of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). The EORTC QLQ-C30 is a 30-item questionnaire comprising 5 functional scales, 3 symptom scales, 1 global health/QoL scale and 6 single items. The score of this questionnaire ranges between 1 and 4 in functional scales, symptom scales, and single items. The score ranges between 1 and 7 in global health/QoL scale. The higher score indicates the worse quality of life.
Time frame: From date of enrollment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years.
Quality of life evaluation

Started Mar 2026 (actual). Primary completion is estimated for Sep 2028, 30 months after the start.
Of 343 non-industry interventional studies with no phase under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 52 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 98. This study's planned 30 months is below that.
Counting every sponsor, half of 359 studies reached it within 51 months; a quarter within 26 and three quarters within 97.
How these figures are worked out, and which studies are left out of them.
