Interventions

  • Bevacizumab (Angiogenesis Inhibitor)
  • Epacadostat (IDO1 Inhibitor)
  • Radiation therapy (Radiation)
  • Retifanlimab (Immune Checkpoint Inhibitor)
Trial OverviewThe study tests combining retifanlimab with radiation therapy and bevacizumab with/without epacadostat in treating recurrent brain tumors. It aims to enhance anti-tumor immune response and improve survival by leveraging the synergy between radiation therapy and immune modulators.
