A Prospective Single Arm Phase II Exploratory Study on the Combination of Whole Brain Radiotherapy, Thiotepa Intrathecal Injection and Systemic Treatment of Primary Diseases in the Treatment of Solid Tumor Leptomeningeal Metastasis

China58 participantsStarted 2024-01-06

Plain-language summary

The goal of this prospective, single-arm exploratory clinical study is to explore the safty and efficacy of whole-brain radiotherapy combined with Thiotepa intrathecal injection combined with systemic therapy for the primary disease in the treatment of leptoeningeal metastases in solid tumors How works well was the combined therapy？ How safe was combined therapy？ Participants will continue systemic treatment, receive HA-WBRT combined with intrathecal injection of Thiotepa. Evaluate the efficacy and safety every 6 cycles. Researchers will evaluate whether this combination treatment is safe and whether it is more effective than previous studies.

Inclusion criteria

. Blood routine: Absolute neutrophil count (ANC) ≥ 1.5'109/L (1500/mm3), platelet count ≥ 75'109/L, hemoglobin count ≥ 9 g/dL (if bone marrow is involved, platelet count ≥ 50'109/L, ANC ≥ 1.0'109/L, hemoglobin count ≥ 8 g/dL).
. Liver function: Serum bilirubin ≤ 1.5 times the upper limit of normal value, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 1.5 times the upper limit of normal value (if liver involvement occurs, AST is allowed, ALT ≤ 5 times the upper limit of normal value).
. Renal function: Serum creatinine ≤ 1.5 times the upper limit of normal value.
. Coagulation function: INR ≤ 1.5 times the upper limit of normal value; PT and APTT ≤ 1.5 times the upper limit of normal values (unless the subject is receiving anticoagulant treatment and PT and APTT are within the expected range of anticoagulant treatment during screening).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
