简要总结
The objective of this study was to evaluate the effect of several ophthalmologic prophylactic treatment strategies for the management of ocular side effects (OSEs) in participants with epidermal growth factor receptor (EGFR)-amplified glioblastoma (GBM) who were being treated with depatuxizumab mafodotin (ABT-414).
详细描述
This Phase 3b open-label, randomized, exploratory study included 2 phases during the treatment period: chemoradiation therapy (radiation plus temozolomide [RT/TMZ]) and adjuvant therapy (TMZ). All participants received depatuxizumab mafodotin during both phases of the treatment period plus 1 of 3 prophylactic ophthalmologic treatments (standard steroids; standard steroids with vasoconstrictors and cold compress; and enhanced steroids with vasoconstrictors and cold compress. The study comprised a screening period of up to 7 weeks after surgery, a 6-week concomitant Chemoradiation Phase, an Adjuvant Phase beginning approximately 4 weeks after completion of chemoradiation, and a Follow-Up Phase.
