Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Further study details as provided by Sun Yat-sen Memorial Hospital, Sun Yat-sen University / Yameitang.
Primary outcome measure: The primary endpoint is the brain injury remission at week 15. In brief, the brain lesion will be evaluated by using brain MRI scan before and after thalidomide regimen. The clinical efficacy is defined as ≥ 25% reduction in brain edema volume on FLAIR images at week 15, as compared with that before thalidomide usage.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Primary objectives: This phase II clinical trial aims to evaluate the indications, therapeutic effects and safety of thalidomide in radiation-induced brain injury.
OUTLINE: This is a phase II, open-label, single arm clinical trial. Patients are enrolled and administrated with thalidomide. Thalidomide is supplied as 25 mg per pill to be taken by mouth.
Arm І: Patients receive thalidomide with a dosage of 25 mg at bedtime daily one week (days 1-7), then 50 mg at bedtime daily for one week (days 8-14), then 75 mg at bedtime daily for one week (days 15-21), then 100 mg at bedtime daily for 12 weeks (days 22-105), in the absence of unacceptable toxicity or severe deterioration.
