“In the Phase 1/2a dose escalation trial, we showed that a rhenium (186Re) obisbemeda radiation dose of 22.3 mCi in an infused volume of 8.8 mL can be safely administered and that there is a statistically significant correlation between overall survival and both absorbed radiation dose to the tumor and percent tumor volume in the treated volume,” said Andrew J. Brenner, M.D., Ph.D., Professor of Medicine, Neurology, and Neurosurgery, Kolitz/Zachry Endowed Chair Neuro-Oncology Research, and Co-Leader of the Experimental and Developmental Therapeutics Program at The University of Texas Health Science Center at San Antonio and principal investigator of the ReSPECT-GBM clinical trial. “The strength of this correlation is unusually positive for a Phase 1/2a trial and we are optimistic that these safety and efficacy signals will be confirmed in the ongoing Phase 2b trial.”
