Safety and Efficacy Study of SL-701, a Glioma-Associated Antigen Vaccine To Treat Recurrent Glioblastoma Multiforme

This is a multicenter, open-label Phase 1/2 study evaluating the efficacy and safety of SL-701 as a treatment for recurrent GBM, divided into 2 stages. Seventy-four (74) participants were treated in the study, 46 in Stage 1 and 28 in Stage 2, men and women at least 18 years of age, all of whom showed unequivocal evidence of either a first tumor recurrence or progression during or following an initial treatment regimen before enrollment in this study. At least 54 of the 74 treated participants had measurable disease based on contrast-enhanced magnetic resonance imaging or computed tomography scans.
