A Study of the Boron Neutron Capture Therapy (BNCT) Using B10 L-BPA in Malignant Brain Tumors

Exclusion Criteria

• •1. Patients with malignant brain tumors complicated by any of the following conditions:
• •* Extracranial metastases.
• •* Multiple intracranial lesions on both sides.
• •2. The investigator assesses that the subject has concurrent infections or other malignant tumors and is not suitable to participate in the trial.
• •3. Patients with malignant brain tumors are considered eligible for standard surgical treatment that is effective against the tumor.
• •4. A time interval less than 3 months from previous radiation therapy for intracranial region.
• •5. A time interval less than 3 months from last brain surgery (excluding drainage procedures and biopsy) and less than 1 month from previous chemotherapy.
• •6. The adverse event of previous anti-tumor therapy were NCI-CTCAE V5.0 grade evaluation ≧ Class 3 (excluding alopecia and peripheral neuropathy).
• •7. Received or expect to receive any investigational drug, biologic or device within 1 month prior to the scheduled BNCT.
• •8. Patients receiving or expected to receive vascular endothelial growth factor inhibitors (except bevacizumab) or live attenuated vaccines within 1 month prior to the scheduled BNCT.
• •9. Patients received major surgery within 1 month prior to the scheduled BNCT or are still recovering from a previous surgery. The investigator will evaluate the subject's condition when the subject receives major surgery. Major surgery is defined as procedure that requires general anaesthesia and/or anticipated hospitalization longer than 24 hours, with significant risk of blood loss or complications. Examples include heart surgery, organ transplants, and prolonged operations such as certain back surgeries. Procedures such as stent implantation, biopsy, endoscopy, and day surgery are excluded.
• •10. Patients who had radiation myelitits or radiation necrosis of the brain/brain stem.
• •11. Patient who is prone to vascular rupture during the trial as assessed by the investigator. The Patient will be eligible for the study if they have undergone stent implantation and obtained consent from the investigator.
• •12. Patients with severe congestive heart failure or renal failure, as well as myocardial infarction, unstable angina, or poorly controlled arrhythmia within 6 months prior to the scheduled BNCT.
• •13. Severe comorbidities, including but not limited to poorly controlled epilepsy, poorly controlled diabetes mellitus, poorly controlled hypertension; chronic lung diseases (e.g., obstructive pneumonia, interstitial pneumonia, pulmonary fibrosis, and severe emphysema); kidney diseases (e.g., chronic renal failure, acute renal failure and nephrotic syndrome); cardiac diseases (e.g., New York Heart Association \[NYHA\] Functional Classification Class III or IV); phenylketonuria; and/or other severe conditions in the opinion of the investigator.
• •14. Suspected or known hypersensitivity (including allergy) to boron or any component of the study drug or contrast media.
• •15. Subject with hereditary fructose intolerance.
• •16. With a cardiac pacemaker or will interfere with MRI-based or CT-based dose-planning or tumor response evaluation.
• •17. Restless subjects who are unable to lie or sit in a cast for more than 30 minutes.
• •18. Any medical or psychiatric conditions that, in the opinion of the investigator, may interfere with optimal participation in the study or place the subject at increased risk of adverse events (AEs).
• •19. Female subject who is planning to be pregnant or lactating during the study period.
• •20. Subject who is considered unfit to participate in the clinical study as assessed by the investigator.
• •21. Subject who has received prior BNCT.
