(PRECISION) A Phase II Study of the Optune System, Enhanced by Genomic Analysis to Identify the Genetic Signature of Response in the Treatment of Recurrent Glioblastoma Multiforme


The purpose of this research study is to collect information on how people respond to treatment with Optune and to see if their response to treatment relates to the genetic make-up of their tumor. Each person who participates in this study will have tumor tissue and blood tested for genetic sequencing, meaning that the exact genetic code of the tumor and blood will be identified.


  • Disease: Brain tumor
  • Disease type: Recurrent Glioblastoma Multiforme (GBM)
