About this study
Official title: Phase I Study of Whole Brain Low Dose Radiotherapy Combined With ICI and Intrathecal Chemotherapy for Treatment of Refractory Meningeal Metastasis of Lung Cancer
This phase I study aims to investigate the safety and efficacy of whole brain low dose radiotherapy (WB-LDRT) combined with ICI and intrathecal chemotherapy for treatment of refractory meningeal metastasis of lung cancer.
Read the detailed description
This exploratory phase I study will be conducted in West China Hospital, Sichuan University. Three cohorts of whole brain low dose radiotherapy (3 patients per cohort) will be enrolled to determine the safety and efficacy of whole brain low dose radiotherapy combined with ICI and intrathecal chemotherapy for treatment of refractory meningeal metastasis of lung cancer.
Subjects who fulfil all the inclusion criteria and none of the exclusion criteria will be enrolled and receive treatment with WB-LDRT at same dose (4 Gy/2f) with diffent cycles (decried as below), PD-1 inhibitor, pemetrexed chemotherapy, and intrathecal pemetrexed every 3 weeks (Q3w) for 4 cycles.
Patients will receive WB-LDRT at 3 cohorts with increasing dose fractions: 4 Gy/2f of one cycle in group 1; 4 Gy/2f of two cycles in group 2; 4 Gy/2f of four cycles in group 3.
- Being tested
- Whole Brain Low Dose Radiotherapy, Pemetrexed, Sintilimab, Chemotherapy

What is being measured
The primary outcome is the main question the study is designed to answer.
Clinical response rate
The RANO proposal for response criteria of leptomeningeal metastasis was used to assess the clinical response in this study.
Measured: 48 months
Incidence of treatment-related adverse events
The incidence of treatment-related adverse events were measured for determing tolerability and safety. Adverse events (AEs) are evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE, version 5.0). Events of grade 3-5 are defined as moderate and severe adverse events.
Measured: 48 months
Secondary outcomes (2)
Neurological progression-free survival (NPFS)
NPFS was defined as time from the start of treatment until neurological progression or death. The neurological progression was determined based on the RANO proposal evaluation criteria which have been established and published on Neuro Oncol.
Measured: 48 months
Overall survival
Survival time was recorded since the date of patient enrollment. All patients were followed up until death or the end of the study.
Measured: 48 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Whole Brain Low Dose Radiotherapy, Pemetrexed and Sintilimab in people with NSCLC and Low Dose Radiotherapy, run by Sichuan University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact You Lu, MD (18980601763 ext. +86, radyoulu@hotmali.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Clinical response rate (time frame: 48 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06431685, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2026.
