Date of first enrollment	08/05/2026
Target sample size	48
Countries of recruitment
Study type	Interventional
Intervention(s)	[Experimental Group: BNCT] Intravenous administration of Borofalan (10B), followed by neutron irradiation using an accelerator-based neutron capture therapy system. [Control Group: BPC (Best Physician's Choice)] Existing drug therapy (e.g., Bevacizumab) selected by the investigator, administered according to standard dosage and administration at each institution.

Outcome(s)

Primary Outcome	Overall Survival (OS)
Secondary Outcome	Progression-Free Survival (PFS) and 6-month PFS rate based on RANO criteria. Best Local Control Rate (LCR) based on RANO criteria. Disease Control Rate (DCR) and Duration of Disease Control (DCD) based on RANO criteria. Timepoint-specific survival rate (e.g., 1-year survival rate). Incidence and severity of adverse events and adverse drug reactions (based on CTCAE).

(3)Patients with active infectious diseases requiring systemic therapy (including HBV, HCV, and HIV). (4)Patients with severe comorbidities (Grade 3 or higher per CTCAE), including cardiac, pulmonary, renal, diabetes, or hypertension. (5)Patients with myocardial infarction, unstable angina, or uncontrolled arrhythmia/epilepsy within the past 6 months. (6)Patients with phenylketonuria, hereditary fructose intolerance, or severe hypersensitivity to drugs or contrast agents. (7)Patients with surgical resection within 30 days or treatment with unapproved drugs within 4 weeks. (8)Patients with contraindications to MRI, or those who are pregnant/lactating or do not agree to adequate contraception. (9)Patients with a history of previous BNCT treatment. (10)Other patients judged ineligible by the investigator or sub-investigator.
