Trial Outcomes & Findings for Study of Intraoperative Radiotherapy for Patients With Large Brain Metastases Treated With Neurosurgical Resection (NCT NCT04040400)

NCT ID: NCT04040400

Last Updated: 2023-10-12

Results Overview

Maximum tolerated dose will be determined by classical 3+3 dose-escalation design. Toxicity will be measured using the National Cancer Institute Common terminology criteria for adverse events (version 5.0). The first dose of 18Gy will be administered to the first 3 subjects, after 90 days from treatment a safety assessment for dose limiting toxicities will be done to determine if the next 3 subject will escalation to dose of 21Gy or receive 18Gy. If escalation to 21Gy is permitted, then after 90 days from treatment a safety assessment for dose limiting toxicities will be done to determine if next cohort of 3 subjects will escalate to a dose of 24Gy or receive 21Gy. The highest dose level to be administered will be 24 Gy if permitted by safety assessments.
