clinical trial The goal of this clinical trial is to learn whether the treatment of advanced non-small cell lung cancer with EGFR-TKIs, when combined with bevacizumab in the presence of positive circulating tumor cells in the cerebrospinal fluid, has better therapeutic efficacy. The main questions it aims to answer are:1.When EGFR-TKIs are sequentially combined with bevacizumab along with EGFR-TKIs for first-line treatment of advanced non-small cell lung cancer, how long can the participants survive? 2.What medical problems do participants have when using EGFR-TKIs sequentially combined with bevacizumab in conjunction with EGFR-TKIs.
Participants will:
Receive EGFR-TKIs treatment for a duration of 3 months, and upon a positive cerebrospinal fluid tumor cell status, subsequently receive bevacizumab combined with EGFR-TKIs treatment until disease progression.
Visit the clinic for check-ups and tests every two weeks, and have follow-up visits every six weeks after the treatment ends.
Keep a record of their symptoms and disease progression.
This study is an open-label, single-arm, multicenter, exploratory clinical trial designed to evaluate and observe the first-line treatment of locally advanced/advanced non-small cell lung cancer that is positive for EGFR mutations, based on the early warning of a novel cerebrospinal fluid CTC capture technology. Subjects who meet all inclusion criteria and none of the exclusion criteria will first receive EGFR-TKIs (osimertinib, amivantamab, or futibatinib) treatment (as per the instruction manual). After a positive cerebrospinal fluid tumor cell status, they will then sequentially receive bevacizumab (7.5mg/kg, intravenous injection, once every 3 weeks) combined with EGFR-TKIs treatment.
Participants Aged 18 years or older (including 18 years old) and up to 75 years of age (including 75 years old); confirmed non-small cell lung cancer through histology or cytology; confirmed EGFR sensitive mutation (exon 19 deletion or L858R) prior to treatment; planned to receive first-line monotherapy with EGFR-TKIs (osimertinib, amivantamab, or futibatinib).
This study is an open-label, single-arm, multicenter, exploratory clinical trial. The primary research objective is to evaluate the overall survival time (OS) of patients with locally advanced/advanced EGFR-mutant non-small cell lung cancer (NSCLC) treated with EGFR tyrosine kinase inhibitors (EGFR-TKIs) sequentially combined with bevacizumab as a first-line treatment, based on the early warning of a novel cerebrospinal fluid circulating tumor cell (CSF CTC) capture technology. The study endpoint is the overall survival time (OS) of the patients. Referring to the results of our team's prospective study data and historical literature review study data, it is anticipated that the hazard ratio (HR) for overall survival (OS) of EGFR-TKIs sequentially combined with bevacizumab compared to EGFR-TKIs as a first-line treatment for high-risk patients with EGFR-mutant locally advanced/advanced NSCLC and leptomeningeal metastasis will be 0.78 (median OS improved from 18 months to 21 months). After the first subject is enrolled, with the longest observation period being 24 months, α set at two-sided 0.05, and a power of 80%, calculating with a 25% CSF tumor cell positivity rate and a 10% loss to follow-up rate, using the NCSS\&PASS 15.0 software and the single-sample Logrank test method, after sample correction, this study plans to enroll approximately 100 subjects.
Based on the investigator-assessed Overall Survival (OS) as the primary efficacy endpoint, the median survival time will be estimated using the Kaplan-Meier method, and the median event time along with its two-sided 95% confidence interval will be presented. Additionally, the hazard ratio and its 95% confidence interval will be estimated as the main analysis.

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.
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.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
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.
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.
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.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
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).
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Participants receive osimertinib orally at a dose of 80mg daily for a 28-day treatment period. After the start of treatment, cerebrospinal fluid is collected every 12 weeks for circulating tumor cell (CTC) examination and routine cytopathological assessment. If the routine cytopathological test is positive, participants are sequentially treated with continued osimertinib at 80mg daily, in combination with bevacizumab administered intravenously at a dosage of 7.5mg/kg of body weight, on the first day of each cycle, with medication given once every 3 weeks. A continuous treatment of 21 days constitutes one treatment cycle. After the initiation of treatment, cerebrospinal fluid is collected every 6 weeks for CTC testing and routine cytopathological examination.
